Tomcat 7上的Spring应用程序问题

Question

When I start my app localy with embeded tomcat 7 everything is working fine. But when I deploy to the remote machine with tomcat7:redeploy (maven plugin) I have problems with the part of the application. App starts fine and parts of it are working, but when I send XML package to the app it throws this exception :

Version of the java on both machines is the same 1.6.45, and there is only this webapp on the remote tomcat instance. I tried playing with the endorsed dir but with no success.

Answer 1

This is the root cause:

I'm guessing that there's a conflict between the Spring version of the JAR and the one that ships with Tomcat. Tomcat's server class loader finds their version first and doesn't have the method that Spring needs.
