I’m still fairly new to Websphere, but this seemed like a pretty common problem someone would have and I couldn’t find anything that properly explained the issue to me. I was running into an issue where WebSphere kept saying it was unable to check if application exists when it was being deployed. I thought initially this was a permissions problem, so I fooled around with permissions but had the same issue. If you scroll down a ways on the stack trace it says
insufficient or empty credentials
I double checked my configuration in Hudson/Jenkins and testing the connection worked fine, so I continued searching for other solutions. There are literally 3 search results on google for “unable to check if application exists” and 0 results on bing. Most of the other articles I found offered no help. Eventually I circled back around and decided to look at the access level my user had in WebSphere. Turns out it wasn’t listed as a user! I’m still not sure how testing the connection in Hudson worked but I wasn’t listed as a user in WebSphere. I checked this half a dozen times just to make sure I wasn’t mistaken.
To add a user in WebSphere
- Users and Groups
- Administrative user roles
- Select the Administrator role
- Enter the user to search for
- Use the arrow to move the user to the Mapped to role box
- Click OK
- Click Save
Step 7 is super important because it requires an additional save than most programs do and I find myself forgetting to do the second confirmation too often. After you’ve added the appropriate permissions redeploy your ear and you should be all set.
