Finally i solved this problem: The ServerException encapsulated a VerifyError that means there was some linkage error executing my compiled bytecode. In fact, this bean was compiled with an old version of Xerces and the container (Tomcat) loads at init time another version of Xerces, and when it instantiates reflectively my class the linkage with Xerces former classes is not performed correctly, because it probably reuses the init-loaded Xerces library.
It sounds a little confusing, maybe because it is confusing!! I hope it could help someone in the future!

I have searched google and it says that the container is creating the instance of my.pkg.MyBean incorrectly, but it seems a *little* weird. I am using Tomcat 4.1.27 Henrique Viecili
