>          Components: Web App/Integration

> Saw this after deploying a new .war file into JBAS4.2.2. Its not reproducible all the time. Steps
> 1) Create a new web app resource by uploading a new .war file
> 2) Get message saying resource has been successfully created
> 3) Browse to the new resource in the list on the main page, note its status is UNKNOWN
> 4) Click on the resource and you are shown a page with the platforms information on, and the exception below is in the logs
> Waiting and trying clicking again doesn't seem to help, but logging out and in again resolves it. The status is shown as available and clicking on the resource name brings up the correct page.
