title: How are custom error pages configured for uncaught exceptions in WebSphere Portal portlets?
body: <p>Out of the box WebSphere Portal displays a generic "This portlet is temporarily disabled." message for any portlet that throws an uncaught exception. </p>
  
  <p>Does anyone know how how this can be overridden - preferably to provide custom error pages for specific exceptions in the same way error pages can be configured in the web.xml of a standard J2EE app?</p>
  
  <p>Using the web.xml of the portlet to define error pages for exceptions does not work. Can't find any documentation on this anywhere.</p>
  
  <p>Using WebSphere Portal 6.1.5, JSR 286 portlets.</p>
