Hello, i have created a new java class, in the src code, after testing i have run the RUN_BUILD. the following happened: My compiere Professional release changed to STANDARD. the changes i have made are functional. Q: How could i upgrade or integrate the new class into a compiere installation without having to reinstall/or change the build.The java class is available in Compiere.jar, i have tried to copy the new Compiere.jar to an existing install, unfortunately it was unable to lunch. So how could i integrate my new class to an existing install without having to reinstall the whole S.W. from the new BUILD.
