We have decided to move our WebSphere servers to a Linux platform for many reason.  We a currently running on Windows 2003 R2. The new server have been installed on CentOS 5.2, with WAS 6.1 and the latest updates (23). I exported one of my working config from the Windows WAS server and installed it as a new application on my new Linux WAS server.  The install went and the application starts.  However, I am unable to access it and only get HTTP 500 screens.  Below is a copy of the server SystemErr.log. These are logged each time the ported application is started.

It's a stack trace. You miss the property file.
The property file is not found, but this won't prevent the application to start. Now, since Java won't allow running a program with ambiguous initialization of a variable, the variable is initialized by the programmer with a null pointer and then it's assigned a value read from the property file. But in this case the variable remains at null and this causes a runtime exception raising when that variable is read and found to be pointing at null..

Found the issue to be related to the certificate keystore shared between the Websphere server and the IHS server.
