When I make an error in my struts logic, the HTML page generation stops at that point and I see truncated HTML pages. However, I cannot find an error message anywhere. For example, I recently didn't define a setter/getter in an ActionForm for an html:hidden field I added to a JSP page, and so struts failed to complete generating the web page.

Is there anyway to get error messages from the struts code on why it fails?

I'm asking because right now I am having to back out changes until I find the offending piece of code which is a slow process, and so I'm looking for a more productive way to find my struts errors.
