OSB SAP Adapter iwafjca.rar Initial Connection

If you are using Oracle Service Bus and integrate it by using SAP adapter, you can face the error below. When I try to update weblogic-ra.xml and change the value for from 0 to 5 it always give deployment update error and the application could not shift to active state. When I rollback to 0 again, it works properly.

The problem is application could not get initial connection and it gives nullpointer exception. This problem is not a bug. I have experienced that “initial connection” must be “0”. So, it doesn’t make sense try to increase it. You have to roll back and set initial connection to “0” (zero). You can give initial connection by using “OSB Application Explorer for SAP Adapter” throug your SAP connection definition.
