I deployed an app on my web server and now I am trying to deply another one on the web server and I am getting a BeanAlreadyExistsException. I thought it might be due to the fact that I have two beans with the same name in the two different projects. So I removed the first project from the server - however that didn't work - I still ended up getting this exception when deploying the second app.
Here is the stack trace:
