After modifying the default WebView listening port value for the property "introscope.webview.tcp.port" in the file, the new WebView URL (http://<hostname>:<port>) fails with error "HTTP ERROR 500".



The root cause of the error is an osgi cache problem and can be resolved as follows: 

1. Stop the Standalone/MOM Enterprise Manager and WebView processes

2. Go to EM_HOME/product/webview/configuration and Delete these 4 directories:

  • org.eclipse.core.runtime
  • org.eclipse.osgi
  • org.eclipse.update

DO NOT delete the file config.ini

3. If directory EM_HOME/work exists, then also delete its contents

4. Restart Standalone/MOM Enterprise Manager and WebView processes

5. Relaunch the Webview URL and the problem should be resolved
