Java wrapper test program using Eclipse 3.1.1

[Joe Byers-2]

I have compiled quantlib, built and complied the java wrapper, cpp wrapper, and skwash examples from skwash.com.

I am now trying to get the SwapValuation example to work.  The example java application hangs/stops but does not exit the program when executing the system.loadlibrary(("QuantlibCPPWrapper"); line.  I built the example from skwash.com as

package test.org.quantlib.examples;

public class SwapValuation {

    public static void main(String[] args) {
        System.out.println("Start SwapValuation\n");
        try {       
//            System.loadLibrary("/DWork/eclipse/workspace/Quantlib/Debug/Quantlib");
//            System.loadLibrary("/DWork/eclipse/workspace/QuantlibCPPWrapper/Debug/QuantlibCPPWrapper.dll");
            System.loadLibrary("QuantlibCPPWrapper");
            System.out.println("SwapValuation ok\n");
        } catch (Throwable t) {
            System.out.println("SwapValuation failed\n");
            t.printStackTrace();
        }
        System.out.println("SwapValuation Exit\n");
//        System.exit(0);
    }
}

I followed the instructions on running/debuging the program and created an environment variable named PATH as ${env_var:PATH};C:\DWork\eclipse\workspace\Quantlib\Release\;C:\DWork\eclipse\workspace\QuantlibCPPWrapper\Release\.  Note I had to add ${env_var:PATH} to the beginning of the variable to get rid of failure to find cygwin1.dll error.  I am also using the relaease directories instead of the debug shown in the example.  Using debug makes no difference to my problem.

Thank you for your help.

Joe

I'm not very knowledgeable about the Java module, but I was under the  
impression that those who compiled it used MinGW rather than the Cygwin  
compiler. Also, I had reports that the wrapper behaved erratically when  
QuantLib was compiled as a shared library---you might want to try  
building it as a static library instead.

Luigi,

Thank you for your suggestions.  I did finally get it to compile (using Mingw) and ran the test suite from Skwash.com.  I had to modify a couple of items in the skwash example and found a problem with eclipse CDT 3.0.2 build options.  I am working on and compilation of the problems and actions to post for future reference for other individuals.

On another note,  I have the algorithm for a calendar of the North American Energy Reliability Council (NERC) holidays.  This is important for pricing derivative on electricity in the US.  Can you point to someone to help develop this for Quantlib calendar module?

Thank you

You can send me either the algorithm or the list of rules for the  
holidays.

Hi,

Apart from the blackcapfloorengine class, I do not believe that any of the
other capfloor engine classes use the spread value stored with the cashflow
coupons. This is also true for the calculated convexity value that is added
to the indexFixing (line #85 of the floatingratecoupon.hpp file).

For example, from line #60 from the analyticcapfloorengine class, the strike
is taken, but then the rest of the computation for the cap is based purely
on discountfactors. Perhaps the strikes need to be adjusted for the
convexity and spread adjustments within the capfloor class, before being
passed into these engines.

If this is possible, then should we use indexFixing() instead of the rate()
function within the capfloor class when populating the forwards array (ie
line #98 of the capfloor.cpp file).

Best Regards,
Toyin Akin.

Jerry,

I would be glad to help you.

First, initial questions and posts should be directed to the quantlib-users list.  Direct contact can follow from the initial posting.

This error I saw many times when trying to get the java and cpp wrappers compiled along with running the tests.

did you get the cppwrapper and javawrapper built?  there should be a cppwrapper.dll file in the cppwrapper/debug tree.  If not, you will have to click on the cppwrapper and right click build project or go the the project menu and select build project from there.

When building the swapvaluation test java script skwash.com says to make sure you have the location of the cppwrapper and javawrapper code in a path variable.  Add ${env_var:PATH}; to the beginning of this path variable so the appropriate cygwin and mingw files can be found.

good luck,
joe

I not see any instruction in the tutorial on how to build the Cpp Wrapper project, but also I don’t understand

what the Cpp Wrapper place holder is for.

Dear Joe,

Thank you very much for your generous help and sorry for being new to mailing list rules.

I'm still stuck. This is what my Eclipse projects look like (images don't show up in mailing lists?) --



There is indeed nothing under QuantLib Cpp Wrapper project and any attempt to build/rebuild
the project only gets --

Nothing to build for project QuantLib Cpp Wrapper

without generating the Debug directory or anything else. Even though there is a quantlib.cxx under
the QuantLib Cpp Wrapper project directory physically.

Similarly, building of the QuantLib Skwash project returns immediately the following without any
real output files --

C:\swigwin-1.3.27\swig.exe -java -c++ -module quantlib -o D:\jerryji's Documents\eclipse\workspace\QuantLib Cpp Wrapper\quantlib.cxx -outdir D:\jerryji's Documents\eclipse\workspace\QuantLib Java Wrapper\org\quantlib -package org.quantlib swig.i

exit status:    0

I must be having a conceptual problem in understanding how Skwash should work, any hint will be
most welcome.

Many thanks in advance!

Jerry,

I am new to all of this as well. 
Do you you have a quantlib project that you built the quantlib.dll?

Also, your javawrapper does not look like you created the org.quantlib package.  you might go back throught the steps for creating the javawrapper on skwash.com.

Also, when you build the skwash project you should see java classes in your javawrapper org.quantlib package and a quantlib.cxx in the cppwrapper.  If these are not there after building quantib skwash then the skwash build using swig is not working. 

I had to delete everything and start over from scratch several time before I worked out the problems.  When building the quantlib project or the cppwrapper project be sure and select debug builds not release.  There is a problem with the eclicpe cdt 3.0.2 release build.

Joe

Dear Joe,

Thank you very much again for your help.

I just re-did everything from scratch again but received the same instantaneous return and the same
message without getting anything under either the Cpp Wrapper or the Java Wrapper project --

C:\swigwin-1.3.27\swig.exe -java -c++ -module quantlib -o D:\eclipse\workbench\QuantLib_Cpp_Wrapper\quantlib.cxx -outdir D:\eclipse\workbench\QuantLib_Java_Wrapper\org\quantlib -package org.quantlib swig.i

exit status:    0

I wonder if anyone has a successful story with the following combination of software packages --

Windows XP Professional SP2
mingw GCC 3.4.2
J2SDK 1.4.2_09
Eclipse 3.1.2
CDT 3.0.2
sKWash 1.0.2
swigwin-1.3.27
QuantLib 0.3.11 release
QuantLib-SWIG-0.3.11.zip

One thing I notice is that the swig.i file generated by the Eclipse QuantLib Skwash project (i.e., it does
not exist in QuantLib-SWIG-0.3.11/SWIG/) is empty, does that mean anything?

Many thanks in advance!

Luigi,

Thank you for your suggestions.  I did finally get it to compile (using Mingw) and ran the test suite from Skwash.com.  I had to modify a couple of items in the skwash example and found a problem with eclipse CDT 3.0.2 build options.  I am working on and compilation of the problems and actions to post for future reference for other individuals.

On another note,  I have the algorithm for a calendar of the North American Energy Reliability Council (NERC) holidays.  This is important for pricing derivative on electricity in the US.  Can you point to someone to help develop this for Quantlib calendar module?

Thank you
Joe W. Byers

I'm not very knowledgeable about the Java module, but I was under the
impression that those who compiled it used MinGW rather than the Cygwin
compiler. Also, I had reports that the wrapper behaved erratically when
QuantLib was compiled as a shared library---you might want to try
building it as a static library instead.

Hi,

 

"One thing I notice is that the swig.i file generated by the Eclipse QuantLib Skwash project (i.e., it does
not exist in QuantLib-SWIG-0.3.11/SWIG/) is empty, does that mean anything? "

 

Yes: that means everything. Please follow the first step of part IV of the tutorial (http://users.telenet.be/johan.witters/website/skwash.com/get/get3apart4.html):

"Before proceeding you need to download the swig interface files of quantlib. These are available from QuantLib CVS Repository. The site explains how to retrieve these files. However, you can use Eclipse for this purpose too. Click here for more info. Make sure you get the Swig Interface Files that match the version of Quantlib which you have downloaded. Also, make sure to download a version of quantlib that supports Java (support available from version 0.3.11). "

I hope this helps.

Cheers,

Johan

Dear Joe,

Thank you very much again for your help.

I just re-did everything from scratch again but received the same instantaneous return and the same

Do you you have a quantlib project that you built the quantlib.dll?

Also, your javawrapper does not look like you created the org.quantlib package.  you might go back throught the steps for creating the javawrapper on skwash.com.

Also, when you build the skwash project you should see java classes in your javawrapper org.quantlib package and a quantlib.cxx in the cppwrapper.  If these are not there after building quantib skwash then the skwash build using swig is not working. 

I had to delete everything and start over from scratch several time before I worked out the problems.  When building the quantlib project or the cppwrapper project be sure and select debug builds not release.  There is a problem with the eclicpe cdt 3.0.2 release build.

did you get the cppwrapper and javawrapper built?  there should be a cppwrapper.dll file in the cppwrapper/debug tree.  If not, you will have to click on the cppwrapper and right click build project or go the the project menu and select build project from there.

When building the swapvaluation test java script skwash.com says to make sure you have the location of the cppwrapper and javawrapper code in a path variable.  Add ${env_var:PATH}; to the beginning of this path variable so the appropriate cygwin and mingw files can be found.

good luck,

Open the properties of your skwash project (right click your skwash project and choose project properties from the popup menu). The main swig interfacefile should refer to quantlib.i instead of swig.i. You, I think, missed step http://users.telenet.be/johan.witters/website/skwash.com/get/get3dpart4.html

 

Hope this helpps

When building the swapvaluation test java script skwash.com says to make sure you have the location of the cppwrapper and javawrapper code in a path variable.  Add ${env_var:PATH}; to the beginning of this path variable so the appropriate cygwin and mingw files can be found.

good luck,

My problem must be more primitive than yours. I have successfully build QuantLib 0.3.11 under eclipse (3.1.2)

CDT. I am using Skwash 1.0.2, and I don’t  get anything under the Cpp Wrapper project, because not only do

I not see any instruction in the tutorial on how to build the Cpp Wrapper project, but also I don’t understand

what the Cpp Wrapper place holder is for.

Many thanks in advance!

P.S. When you reply, could you please “reply to all”, which will also include my personal address.

I'm not very knowledgeable about the Java module, but I was under the
impression that those who compiled it used MinGW rather than the Cygwin
compiler. Also, I had reports that the wrapper behaved erratically when
QuantLib was compiled as a shared library---you might want to try
building it as a static library instead.

Jerry,

Your skwash build is not configured correctly, the swig.i should be ql.i.

Check your skwash project properties quantlib skwash properties out.  Right click on quantlib skwash and select properties.  you should have the following (note the italics are for my setup and should be modified to fit your projects)
General tab
main swig interface file --------  ql.i

Do you you have a quantlib project that you built the quantlib.dll?

Also, your javawrapper does not look like you created the org.quantlib package.  you might go back throught the steps for creating the javawrapper on skwash.com.

Also, when you build the skwash project you should see java classes in your javawrapper org.quantlib package and a quantlib.cxx in the cppwrapper.  If these are not there after building quantib skwash then the skwash build using swig is not working. 

I had to delete everything and start over from scratch several time before I worked out the problems.  When building the quantlib project or the cppwrapper project be sure and select debug builds not release.  There is a problem with the eclicpe cdt 3.0.2 release build.

Dear Joe,

Thank you very much for the tip. Since quantlib.i ends with the instruction --

%include ql.i

I believe Mr. Witters' advice (of setting main swig interface file to "quantlib.i") is more generic,
although the results should be the same as far as building Java module is concerned because
Java related instructions seem to appear only in ql.i

Now my Cpp Wrapper finally compiles, though with tons of the following errors that are very
greek to me --

C:\DOCUME~1\jerryji\LOCALS~1\Temp/cc4gaaaa.s:924100: Warning: .stabs: description field '114b3' too big, try a different debug format
C:\DOCUME~1\jerryji\LOCALS~1\Temp/cc4gaaaa.s:924101: Warning: .stabs: description field '114b3' too big, try a different debug format
Finished building: ../quantlib.cxx

and (hence) ends with many linker errors --

./quantlib.o(.text$_ZN8QuantLib24DiscretizedVanillaOptionC1ERKNS_14OneAssetOption9argumentsE[QuantLib::DiscretizedVanillaOption::DiscretizedVanillaOption(QuantLib::OneAssetOption::arguments const&)]+0x4c):c:/Dev-Cpp/bin/../lib/gcc/mingw32/3.4.2/../../../../include/c++/3.4.2/bits/stl_algobase.h: variable 'vtable for QuantLib::DiscretizedVanillaOption' can't be auto-imported. Please read the documentation for ld's --enable-auto-import for details.
collect2: ld returned 1 exit status
make: *** [QuantLib_Cpp_Wrapper.dll] Error 1

Sorry for being the spammer of the day. I am a little desperate, especially when knowing I'm
almost there...

Many thanks in advance.

Dear Johan,

You are the hero! (and I'm the stupid)

My Cpp Wrapper project finally compiles fine, but hit the following linker error --

collect2: ld returned 1 exit status
make: *** [QuantLib_Cpp_Wrapper.dll] Error 1
make: Target `all' not remade because of errors.
Build complete for project QuantLib_Cpp_Wrapper

I scanned through the Cpp Wrapper project properties tabs but didn't find anything comes
close to --enable-auto-import. Well, I could have googled deeper, but wonder if that's again
due to some stupid things I did that you (or anyone) takes only two seconds to point out.

Thanks!

Dear Johan,

Thank you very much for pointing it out, before which I thought I've read every page of the
Skwash tutorial many times. I just checked out the SWIG CVS branch R000311f0 (sorry to
the text mailing list users for the image of my Eclipse project view) --



However, there is still no this swig.i file that I was hoping for --

In fact, the CVS checkout directory is identical to QuantLib-SWIG-0.3.11/SWIG/ in the release

Yes: that means everything. Please follow the first step of part IV of the tutorial (http://users.telenet.be/johan.witters/website/skwash.com/get/get3apart4.html):

"Before proceeding you need to download the swig interface files of quantlib. These are available from QuantLib CVS Repository. The site explains how to retrieve these files. However, you can use Eclipse for this purpose too. Click here for more info. Make sure you get the Swig Interface Files that match the version of Quantlib which you have downloaded. Also, make sure to download a version of quantlib that supports Java (support available from version 0.3.11). "

I hope this helps.

Cheers,

Johan

I just re-did everything from scratch again but received the same instantaneous return and the same
message without getting anything under either the Cpp Wrapper or the Java Wrapper project --

C:\swigwin-1.3.27\swig.exe -java -c++ -module quantlib -o D:\eclipse\workbench\QuantLib_Cpp_Wrapper\quantlib.cxx -outdir D:\eclipse\workbench\QuantLib_Java_Wrapper\org\quantlib -package org.quantlib swig.i

exit status:    0

I wonder if anyone has a successful story with the following combination of software packages --

Windows XP Professional SP2
mingw GCC 3.4.2
J2SDK 1.4.2_09
Eclipse 3.1.2
CDT 3.0.2
sKWash 1.0.2
swigwin-1.3.27
QuantLib 0.3.11 release
QuantLib-SWIG-0.3.11.zip

One thing I notice is that the swig.i file generated by the Eclipse QuantLib Skwash project (i.e., it does
not exist in QuantLib-SWIG-0.3.11/SWIG/) is empty, does that mean anything?

Many thanks in advance!

Jerry,

I am new to all of this as well. 
Do you you have a quantlib project that you built the quantlib.dll?

Also, your javawrapper does not look like you created the org.quantlib package.  you might go back throught the steps for creating the javawrapper on skwash.com.

Also, when you build the skwash project you should see java classes in your javawrapper org.quantlib package and a quantlib.cxx in the cppwrapper.  If these are not there after building quantib skwash then the skwash build using swig is not working. 

I had to delete everything and start over from scratch several time before I worked out the problems.  When building the quantlib project or the cppwrapper project be sure and select debug builds not release.  There is a problem with the eclicpe cdt 3.0.2 release build.

Dear Joe,

Thank you very much for your generous help and sorry for being new to mailing list rules.

I'm still stuck. This is what my Eclipse projects look like (images don't show up in mailing lists?) --



There is indeed nothing under QuantLib Cpp Wrapper project and any attempt to build/rebuild
the project only gets --

Nothing to build for project QuantLib Cpp Wrapper

without generating the Debug directory or anything else. Even though there is a quantlib.cxx under
the QuantLib Cpp Wrapper project directory physically.

Similarly, building of the QuantLib Skwash project returns immediately the following without any
real output files --

C:\swigwin-1.3.27\swig.exe -java -c++ -module quantlib -o D:\jerryji's Documents\eclipse\workspace\QuantLib Cpp Wrapper\quantlib.cxx -outdir D:\jerryji's Documents\eclipse\workspace\QuantLib Java Wrapper\org\quantlib -package org.quantlib swig.i

exit status:    0

I must be having a conceptual problem in understanding how Skwash should work, any hint will be
most welcome.

Many thanks in advance!

Jerry,

I would be glad to help you.

First, initial questions and posts should be directed to the quantlib-users list.  Direct contact can follow from the initial posting.

This error I saw many times when trying to get the java and cpp wrappers compiled along with running the tests.

did you get the cppwrapper and javawrapper built?  there should be a cppwrapper.dll file in the cppwrapper/debug tree.  If not, you will have to click on the cppwrapper and right click build project or go the the project menu and select build project from there.

When building the swapvaluation test java script skwash.com says to make sure you have the location of the cppwrapper and javawrapper code in a path variable.  Add ${env_var:PATH}; to the beginning of this path variable so the appropriate cygwin and mingw files can be found.

good luck,
joe

Hi Joe,

My name is Jerry, a new QuantLib user. I hope you don’t mind such a direct mail.

I am also following the QuantLib Skwash tutorial but am getting nowhere, it would be greatly appreciated if

you could share your findings. I’m getting the following error when running the example swap java code --

SwapValuation failed

java.lang.UnsatisfiedLinkError: no QuantLibCppWrapper in java.library.path

      at java.lang.ClassLoader.loadLibrary(Unknown Source)

      at java.lang.Runtime.loadLibrary0(Unknown Source)

      at java.lang.System.loadLibrary(Unknown Source)

      at org.quantlib.examples.SwapValuation.main(SwapValuation.java:7)

My problem must be more primitive than yours. I have successfully build QuantLib 0.3.11 under eclipse (3.1.2)

CDT. I am using Skwash 1.0.2, and I don’t  get anything under the Cpp Wrapper project, because not only do

I not see any instruction in the tutorial on how to build the Cpp Wrapper project, but also I don’t understand

what the Cpp Wrapper place holder is for.

Many thanks in advance!

P.S. When you reply, could you please “reply to all”, which will also include my personal address.

Subject: Re: [Quantlib-users] Java wrapper test program using Eclipse 3.1.1

Luigi,

Thank you for your suggestions.  I did finally get it to compile (using Mingw) and ran the test suite from Skwash.com.  I had to modify a couple of items in the skwash example and found a problem with eclipse CDT 3.0.2 build options.  I am working on and compilation of the problems and actions to post for future reference for other individuals.

On another note,  I have the algorithm for a calendar of the North American Energy Reliability Council (NERC) holidays.  This is important for pricing derivative on electricity in the US.  Can you point to someone to help develop this for Quantlib calendar module?

Thank you
Joe W. Byers

I'm not very knowledgeable about the Java module, but I was under the
impression that those who compiled it used MinGW rather than the Cygwin
compiler. Also, I had reports that the wrapper behaved erratically when
QuantLib was compiled as a shared library---you might want to try
building it as a static library instead.

I don't know whether this will solve your problem, but I suggest to  
build QuantLib as a static library instead of a shared one; I've had  
reports of erratical runtime behavior when compiling it as a DLL (for  
details, look for "Euribor1d act/360 history not loaded" in this  
mailing list's archive.)

Johan, may you update your guide so that a static library is built?

Later,

Eureka! Thank you all for your generous help, I finally got my
"SwapValuation ok" :)

The key, to me, is indeed to compile QuantLib (0.3.11) as static
library. I couldn't agree with
Luigi more that it would be greatly appreciated by all new comers if
Johan would, when time
permits, update your JQuantLib tutorial site to give them more faith in
QuantLib and sKWash,
both fantastic tools!

Thank you all (Joe, Johan, Luigi) again.

I have no intention of double-posting, just that my previous message is
being reviewed by
moderator due to its large size.

I wonder if someone could send me a simple European or American option
pricing Java test
code (utilizing QuantLib, of course).

Thanks!

Luigi,

I am working on a short document covering the rules for holiday in NERC for you.  It will include links to the NERC website documents and other North American ISO's.  The document will also include rules for determining On Peak, Off Peak, and Weekend hours.  This component is a little more of a problem than just the holidays.  I notice that Quantlib DATES do not have hour capabilities.  While this is not a problem for valuing an On Peak forward or other derivative since the On peak price is the average of a 16 hour block, it is a problem for valuing hourly derivatives. 

I just wanted to let you know that I have not forgotten about this project.

You can send me either the algorithm or the list of rules for the
holidays.

I am working with the QuantlibAddin and I have questions about the environment variables that we create.  QL_DIR, QUANTLIBADDIN_DIR, and OBJECT_HANDLER_DIR are the variables of interest.  I am working on this on a WinXP machine and do not think I will have these questions on my LINUX machine because LINUX install everything to /usr/XXX/XXXX.

Can I put all the static libraries in one location like \Libraries\QLSTUFF\lib and the addin will work?  For Excel and OO?

Or do I need to have seperate lib directories for each QL module?

I would like to install QL in our Risk Management lab at the University of Tulsa.


Thank you
Joe Byers
