Hi Serge Huber, my instalation was made by CVS source on my previous
Tomcat instalation, but my problem was solved, my error was in the
directory structure, it was this:

--MyWebapp
   |---MyWebapp.java
   |---MyWebapp.class
   |---WEB-INF
         |---web.xml

Now is this (and works =D) :
--MyWebapp
   |---WEB-INF
         |---web.xml
         |---classes
               |---MyWebapp.java
               |---MyWebapp.class


Thanks a lot...=]
