Likely easier to debug if you just type the URL for the image into the browser's address bar.

Use the browser tools to inspect the response for correctness.

Another thing you may need to know.
Just because you TOLD the server to redirect the response doesn't mean the current page stops running
After issuing a forward/redirect, you should immediately return from your page.

The problem seems to be related to axis2 configuration. Checking out this link: https://issues.apache.org/jira/browse/AXIS2-5383
