1. Initial context factory is changed to com.pcbsys.nirvana.nSpace.NiravanaContextFactory
2. webMethods specific JCA resource adaptor is to be created in JBoss application server level. This resource adaptor needs properties specific like connection factory jndi name, JNDI Properties(pointing to right initial context factory), provider url to the target system.
This is basically for prpc to understand the initial context factory class mentioned and locate it appropriately. All the app server level changes can easily be done through JBoss admin console.
At PRPC, initial context factory and provider url are used in JNDI Server rule instance.
