Deploying a J2EE project puts the following exception in the Eclipse .log. Also, unable to remove the deployment config – gives the same exception.

Are there any errors in the Eclipse log? (<workspace>/.metadata/.log)
Yes, see first post

I was looking at the NPE and hypothesizing that this may be an edge condition in the codebase. Here are a couple of more questions:

1) Are any of the appserver connectors enabled? The complement of this question is, are all of the appserver connectors disable?

2) Are there any J2EE project’s in your workspace?

If either of these is true then this is probably and edge condition.

1) Yes, there is exactly one appserver enabled. It is the JBoss 3.2.1 appserver I mentioned earlier.
2) Yes. There would have to be a J2EE project to be able to select a J2EE project to deploy.

Too bad MyEclipse was not compiled with debug turned on – then you would know the line number the error is occuring at, at least.

Knowing this is an edge condition doesn’t help me much. I can neither run nor remove this deployment. Clicking either “Redeploy” or “Remove” causes the same exception. I could delete the project I suppose, but that sems like a bit of overkill.

[support-michael]

I realize the edge condition hypothesis does not help you. I should have kept it to myself (I was just thinking out loud and trying to provide context for questions that might seem trivial).

Another question:
1) Can you start and stop JBoss from through the MyEclipse JBoss connector. If NO then there is a configuration error in the connector that is tripping the deployer.

If #1 is all OK then try this:
1) shutdown MyEclipse
2) restart MyEclipse
3) creating a simple Web Project with 1 JSP and see if you can deploy/undeploy it.

[Don Laidlaw]

For some reason stopping and starting MyEclipse clears out the project deployment, and on the next attempt it works.

I also did this with a fresh, small deployment built from scratch. You must exit MyEclipse and restart before you are able to create project deployments.

This can be closed
