Deploying an EAR with Tomcat

[Jonathan Gallimore <jo...@gmail.com>]

Hi,

I just gave this: 
http://www.nabble.com/Tomcat-hot-deployment-td13287215.html a go, and I 
encountered a minor problem where all my beans were being deployed 
twice, and I was getting this error:

org.apache.openejb.DuplicateDeploymentIdException: Application cannot be 
deployed as it contains deployment-ids which are in use: app (and a list 
of all my EJBs)

Looking at what was going on with a debugger attached it looked like the 
app was actually being deployed twice, once with the name of the 
directory that the ear is expanded into, and once with the name of the 
actual ear itself.

If I stop Tomcat, delete the ear file from the webapps folder, and leave 
the folder the ear was expanded into alone, and restart Tomcat, it works 
perfectly.

Am I doing something wrong?

Cheers

Jon

Hmm... Sounds like the directory watching code is clearly getting  
triggered while we are in the process of (or right after) we deploy  
the ear file.  The outcome is good as a second copy will not be  
deployed, just the error message is annoying and we should find some  
way to prevent that second deploy.  Not quite sure how.
