> This feature addresses a 'user experience' problem: displaying stack traces to the end user. For example, If I change my database connection to a bad setting, and then try to hit the portal, I get this in my browser:
> javax.servlet.ServletException: Failed to initalize jetspeed. org.apache.jetspeed.exception.JetspeedException: Unable to create Engine
>     org.apache.jetspeed.engine.JetspeedServlet.doGet(JetspeedServlet.java:206)
>     javax.servlet.http.HttpServlet.service(HttpServlet.java:689)
>     javax.servlet.http.HttpServlet.service(HttpServlet.java:802)
> Ugly.
> I propose that the Jetspeed engine always completes initialization, even  on error conditions. The engine will have 'state' attribute to determine if the engine is running or in
> engine.getState()
> returning states such as RUNNING, INITIALIZING, DOWN, ERROR
> Then a valve can check the engine state, and redirect to servlet pages based on the state, or pass thru on the RUNNING state.
> This leads to an interesting challenge: what if the database comes up?
> Should we just restart the app server?
> Thats certainly the easiest solution.
> A retry thread would be another solution
