I think this is because you are trying to use a class on the jsp that has
been modified by an aspect. I had the same problem. You can't do this
unless your jsp compiler supports aspects and weaves the aspects in. You
can still use aspects in your J2EE applications but the aspects can't add
any new members to those classes being used in the jsps. I don't know of
any jsp compilers right now that support aspects but they're coming.
I would be good to hear of any solutions to this problem if any one else
knows any.

I've never tried this, but don't see why it should be a problem.
Jsp compilation is a two stage step.
(1) compile Jsp to Java (Jasper uses a class called JspC)
(2) compile Java to Class using javac
I don't see a reason why you shouldn't just replace javac in (2) with
the AspectJ compiler...
How exactly you do this will depend on whether you are precompiling or
compiling on the fly, and the JSP engine you are using.
Of course, it's possible that your vendor does a direct Jsp->class
compilation, in which case I am talking rubbish - but I haven't seen one
yet...
Whether you are using 'call' or 'execution' will also impact you (I
think) if you are trying to call across mixed compilation modules....
Hope that helps,
Jules
