Java class files for tomcat, where? [message #1735581]

Learning web server programming (java, tomcat) using the tutorial found on jsptut.com. When I come to 'Beans and Forms Processing' I run into trouble: Where in the project should I store the java class UserData.java definition file? And how to compile it within Eclipse? Finally, where should teh UserData.class file go?

A working solution found by trial-and-terror is to store the .java file under Java Resources/src/<package name>, mark the .java file and hit Run. This creates a .class file in the build/classes/<package name> directory. I copy this .class file to WEB-INF/classes and restart the server.

I run Eclipse Mars.2, JDK 1.8 and Tomcat 8 on a CentOS 6 host.

It's probably better to ask on the Web Tools forum. Maybe this helps:

Maybe. Actually I have found at least one working solution: When creating a new class in the package folder, the type should be Servlet, not Class. Another workaround (if type is set to class) is to copy the .class file (found in the build folder) to the WEB-INF/lib folder.

Any comments on that are most welcome.

Seams to me like another problem.
