I have a Jar file(an application) which works with some other third party applications(exe files) in the machine.
Now, I have to call the Jar file from a web application, which in turn should work with the Third party applications.
C as said by the professionals above just place the jar file in the "lib" folder of your application and then restart the server and then run your application
the jar file which you have placed will automatically be referenced by the application...
and regarding the exe files where ever you are using the exe just give the path of that exe and mind it you placce the exe in the same path as given in the code of your library class....
