Tomcat 7：从Tomcat 6迁移-Invoker Servlet

Question

Actually i'm working with an old Web Application (it's development has 10 years). Earlier, the webapp worked in Tomcat 5.x and, actually it's working in Tomcat 6 (6.0.28) and it's using the " evil " Invoker Servlet.

We are trying to migrate to Tomcat 7, and searching a way to get invoker servlet work we've seen that it's complicated (And, the "solution" it's quite similar to map every Servlet in web.xml file).

Today, the project has about 2600 classes, and we have a serious problem: Map every servlet.

Question: is there a way to "optimize" the mapping of the complete application? I don't know, some tool that can help me to get the qualified name of every servlet. I'm on charge of this project, and i don't know how to begin with this...

Another Problem: We don't have the complete source code, actually, if i want to do any change in the webapp, i must "Decompile" the .class file (we're using Gel for decompile .class files), repair any error and compile the file again, so, Servlet 3.0 Annotations for mapping doesn't seems a good idea.

Any suggestions are gladly accepted.

Edit: Now, i will try to Map every servlet. But, i have a question: This task can be done in a different file than web.xml? This question is because of the extense list of servlets, and the future management of this file.

Thanks in advance

Ok. I'm sorry if i've asked a "no-sense" question. The Only way to solve this was mapping every servlet in web.xml file.

After an extensive search googling and, through stackoverflow, there's no other option than the WebServlet annotation or web.xml mapping.

There's no easy way, and "recreate" the invoker servlet wasn't a practical option.

Thanks to everyone.
