RE: JspException: Exception thrown by getter for property XXX of bean YYY?

["Chen, Gin" <Gi...@NielsenMedia.com>]

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

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

*** code ***

    public String getPreviousUrl() {
        return ((null != previousUrl) ? "<a href=\"" + previousUrl +
"\">&#171;</a>" : "&#171;");
    }

*** stack ***
