Looking at the source for the introspecthelper, I see that it will throw
a JasperException with a message on jsp.error.beans.noproperty or
jsp.error.beans.nomethod.setproperty errors. The rest is clumped into a
try that throws a JasperException without a message. I'm looking at this
trying to find out what would be failing and throwing the exception in
this case. Any help would be appreciated. What servlet API spec is
tomcat 3.2 using? I was looking at the servlet 2.1 spec and its
ServletException class (which the JasperException class is based on)
doesn't have a constructor to only take an exception. The only one that
takes an exception as an argument also takes a String message (public
ServletException(String message, Throwable rootCause)).
I'll be looking for an email with any help while I wade through the
src...
