I have never compiled the Java module on Windows, so I can't give detailed instructions (if someone did, by all means please step in). However:

- no, you don't need SWIG or sKWash. The Java files are already generated.

- yes, there's one single quantlib_wrap.cpp file that should be compiled into a DLL. The instructions you linked are for Linux or Cygwin, so they're not the ones you;re looking for, But right above them there's a link to the SWIG wiki for help with other systems, so I suggest you to have a look there.

Hope this helps,

Luigi

Sorry to double e-mail, but I forgot to mention I'm using a 64-bit machine and can use Microsoft Visual Studio or Eclipse easily.

Thanks,

Hello everyone,

I am trying to understand how to use QuantLib in Java, but have been confused as to the process for a few weeks. I found QuantLib-SWIG-1.5.zip on SourceForge, which seems to have all the .i and the .java, files, as well as a file called quantlib_wrap.cpp.

The README says to follow these instructions, but it is a bit confusing. Do I need to even tough SWIG or sKWash, because I already have the .java files?

In addition, on SWIG's website, it says under the "Building a Java Module" to do the following commands:
 $ swig -java example.i
 $ gcc -c example.c example_wrap.c -I/c/jdk1.3.1/include -I/c/jdk1.3.1/include/win32
 $ gcc -shared example.o  example_wrap.o -mno-cygwin -Wl,--add-stdcall-alias  -o example.dll
This makes me think that for each .cpp file in QuantLib, we'd need a wrap.cpp file to correspond and compile it with. Instead, I notice one huge quantlib_wrap.cpp (and quantlib_wrap.h) files. What commands need to be typed in? 
Basically, if someone could provide me with a detailed guide on how to take the materials in QuantLib-SWIG-1.5.zip and turn it into a functioning QuantLib in Java, I would really appreciate it!
Thanks,
Tanvi
