jebroni,
Sorry that you are seeing this issue.
Can you answer some more questions for us?
1. Can you please share the Installation Details from MyEclipse > Installation Summary > Installation Details? Paste them here for us.
2. Can you check if you can deploy the un enhanced project from RAD to WAS 7 outside of MyEclipse without any issues?
3. Can you also check if you can create a simple project in MyEclipse, deploy to WAS and check if you see the same issue ?
4. Clear the contents of the deployment log, now try deploying the converted project from RAD and paste the contents of the deployment log here for us.
5. Please take a look at this link :
