Question

Hi,

I'm trying to start JBoss example application 'jboss-as-helloworld'. And got such exception:

JBoss 7.0 Runtime Server has started and I can access JBoss start page http://localhost:8080 and JBoss console.

I didn't change any code or xml, everything is default. Tell me if it is need to provide additional info to investigate this issue.

Answer 1

From the error, it looks like "Hello world" already deployed on the server (perhaps you selected to install examples):

Caused by: org.jboss.msc.service.DuplicateServiceException: Service jboss.naming.context.java.app.jboss-as-helloworld is already registered

Try undeploy this app and then deploy again. Or you could rename your first "hello world" app and deploy - so there is no name conflict.

Answer 2

These are the steps I followed to resolve the issue.

1. Stop the Server.
2. Go to deployment path.
3. Manually deleted the existing project in deployment folder.
4. Restarted the server
5. Deployed the application again.
