Premigration considerations: Common code utilities

IBM recommends that you avoid the development of common code utility libraries for use across integration artifacts within the WebSphere InterChange Server or WebSphere Business Integration Server Express environment. Consider using EJBs running in WebSphere Application Server to encapsulate the logic, and use web service calls to invoke them from WebSphere InterChange Server or WebSphere Business Integration Server Express.

While it is possible that some common code utility libraries may run appropriately on IBM BPM, you will be responsible for the migration of the custom utilities.
