Flow of communication:
1) Application client (Swing) <-> APPSERVER (Weblogic and / or JBoss 3 / 5) <-> Weblogic
2) Browser (Web) <-> APPSERVER (Weblogic and / or JBoss 3 / 5) <-> Weblogic
The idea is to gradually migrate all 32 servers JBoss 3 for the newer version (JBoss 5) keeping the communication above safe. In preliminary tests, I found some errors in serialVersionUID and I was forced to correct the sources of JBoss 3 to make it compatible with newer version.
However, the error below raised a question: Is it possible to have this structure? How?
