[JCS] Error starting web service with JCS on WAS 8.5.5 (Linux only)

[Barry Lulas <bl...@teknovare.com>]

Hello,

I have created a web service for WebSphere that uses a basic JCS configuration.  When I package and deploy for WAS under Windows on my local machine I have no issues.  When I deploy that same .ear file to my WAS running on Linux I get the following exception when I try to start my service in the WAS console:

At first I figured it was an issue with WAS finding the cache.ccf file, but since it works fine under WAS Windows that wasn’t the problem.  Then I thought maybe it was a problem with the disk auxiliary cache settings, so I removed them, that didn’t solve the problem.  No matter what I do the service won’t start under Linux.

Given the exception included, can somebody please point me in the right direction on how to solve the problem?

It looks like the caching manager cannot find its configuration. What is
the config location you provided when starting the caching manager?
The default is loading the file jcache.ccf from the class loader, if I
understand the code correctly.

Bye, Thomas.
