Hey, I was so enthusiastic to check tomcat 3.3.1 b1.... and it really solved the problem!!! It's like this fix especially made for us :)-. Thank you !!!!!!!!!!!
However, I've still one open question concerned the reloading: After the jar file is reloaded successfully, the previous session is lost. That's strange, cause I only save there String variables. Does it have any solution ?

A new attribute, use11Loader, was added to <LoaderInterceptor .../> as a workaround. If you can, give Tomcat 3.3.1 Beta 1 a try with use11Loader="true" and see if you still have the problem. See: <http://jakarta.apache.org/tomcat/tomcat-3.3-doc/serverxml.html#LoaderInterc eptor11> for details.
