I am maintaining a j2ee web application that was built years ago. The jsp page does have java code. There is no ant or maven for building war files. Any change that I make to the java code, I compile them put the class files in the production server. What if the change is in the java code of the jsp file? How do I compile the jsp page? I tried making the changes to the java code in the jsp page. and restarted the apache tomcat server, but the application did not reflect the change. I just want to know if the procedure is right. Is that how generally jsp files with java code compiled?
