Deployment problem of GWT RPC application on Tomcat 5.5
Mikhail
I try to deploy GWT RPC application which uses 3d party libraries. In
GWT hosted mode application works fine. But when I deploy application
on Tomcat I have got nullpointerexception (see tomcat log below).
During execution time it seems client works fine and application fails
when tries to get data from server (DataServiceImpl).
Could anybody help me?
