Different Java versions applications is not working in Tomcat 6 server

We have two Struts 2 web applications with different Java environments. One is Java 1.5 and another one is Java 1.6.

These two applications must be run in my production server (Linux environment) the versions there are Java 1.6 and Tomcat 6.

I get the exception in my production server like:

[ INFO] 2011-04-15 12:59:00,221 [BasicTilesContainer] (BasicTilesContainer.java:init:116)
Initializing Tiles2 container. . .

Please suggest a solution.

I suggest you talk to the developers of the application that is failing and ask them about this, or at least ask them how to enable better error reporting.
