JspException: Exception thrown by getter for property XXX of bean YYY?
We've had some additions to our production Struts app out for two months,
and today is the first time I have seen this specific error (see below).
I've includded the getter method below. How could an exception be thrown by
this method? It should handle the case where previousUrl is null.
Thanks,
- Alex

look further down the trace.
there's a line that says root cause.
the exception after that is your true error.

RE: JspException: Exception thrown by getter for property XXX of bean YYY?
Thanks for the responses. I'm obviously missing some basic JSP debugging
skills ;) Although I've been working on a "50% Struts" app for a year+ (i.e.
tons of scriptlet code in JSPs), I've only just started using Struts
properly with ActionForm's and taglibs so I'm still a noob when it comes to
debugging JSPs.
When you say, "look further down the trace", do you mean the stack trace I
forwarded in my posting or some other stack dump? I don't see anything
labelled "root cause" in that trace.

Actually its in the same stack trace as what you posted but further down.
Make sure that you are looking at the console when getting the stack trace
and not the web page.
If you can't find it in the console then look into your log files.
I dont know if the root cause stack trace is application server specific but
either way, there should be something like it that will point you to a
better description of what caused the error.
