- WebSphere Classic
- WebSphere Liberty Profile

The purpose of this is to set up a simple working cluster to allow developers to ensure that their work will function correctly in a clustered environment and neither a robust system with failovers nor scaling.

To work around it I took some hints on Arjan Tijms’ work testing with JASPIC on WebSphere Liberty and combined it with my knowledge of Maven and OSGi.
