Again, specifically you need the Init servlet to be present in web.xml and set to load on startup. If it has been correctly installed, you will see a series of logs at startup describing various server-side initialization. At that point it is impossible for the "config" variable to be null.

Init servlet is loaded, please see the below logs.

If I suspend the thread on NullPointerException and check for config object, value of the config object is still NULL.

We suspect that we are being fed bad data again. The initialization messages you show can only appear if config is set non-null.

It may be that you have more than one .war being deployed and so separate copies of the Config class are being created, one validly initialized and others not. If so, try moving Isomorphic .jars to the system classpath instead of WEB-INF.
