I'm hoping that someone can help me out, I'm running out of theories...I've included the stack trace and, what I think is relevant snippets from the files involved. If someone could even suggest a way to debug this I'd appreciate it....
Below is part of the exceptions stack trace: javax.servlet.jsp.JspException java.lang.Throwable(java.lang.String) java.lang.Exception(java.lang.String) javax.servlet.jsp.JspException(java.lang.String) void org.apache.struts.taglib.html.FormTag.lookup() int org.apache.struts.taglib.html.FormTag.doStartTag() void _0002fassayType_0002ejspassayType_jsp_1._jspService(HttpServletRequest, HttpServletResponse) . . . .
