This is a bug with JBoss that should hopefully have been fixed for the next release.

When you deploy an ear it is registered as part of the deployment process. When you undeploy it the ear should be unregistered.

If you deploy the ear and verification fails the ear is not unregistered when you undeploy it, this means that for all subequent deployments even if they are valid you will get the error you are getting now.

For the moment the simplest workaround is to restart JBoss or alternatively try deploying the ear with a different name.

But I don't now how to deploy any application, this is my first time in this subject :(

Hi
Interesting ,I too got the same Error for the first deployment (of course on win 2000) with JBOSS4.02 and Eclipse IDE 3.01.

My Hacking way was to Search the '/JBOSS4/server/default/deploy'

for all 'Fibo.ear' and delete the same, Restart the Jboss4 for cleanup Startup.


Hope this works with u guys.

Deployment with JBoss is simply the process of copying the FibboApp.ear to the server/default/deploy folder, JBoss will recognise the archive and deploy its contents.

When following the JBoss-IDE tutorial (Chapter 11) this is what it does for you when you.

As karthik says, remove all instances of FibboApp.ear from the deploy folder and restart JBoss. Then when you try and deploy see if there are any different deployment errors.
