Websphere hosting OpenCms, development setup

We are using Webspehere APP server RATIONAL application developper (RAD).
We are planning to use opencms (we already have expertese with it using TOMCAT).

The challenge is seting up the DEVELOPMENT environment for opencms.

After completing the setup-wizzard of OPENCMS, it generated a virtual drive structure UNDER the WEB-INF folder.

Now, from the IDE (rad 6.0 in this case), we had published to the embedded Websphere testenvironment, but after shutting down the IDE, the modifications done by OPENCMS to the file-system are discarded.

Then we were using the EXTERNAL full websphere application server (both 5.1 and 6.0 have been tested), we just cannot seem to RUN against a server the KEEPS the state of the code on the serer intact.

For you comparison: with TOMCAT this is easily solved. in the SERVER.XML we set the CODEBASE of the opencms <Context> to point directly to the CODE generated in the IDE, in such way that IDE and Server both use the same code at all times.

After 3 weeks, we have no solution, does anybody have experience with this ?
