can someone provide some insight on the following exception? thanks
I look on PostMessage_2.java which was generated dynamically by jsp, on the line where
the exception occured:
org.apache.jasper.runtime.JspRuntimeLibrary.introspect(pageContext.findAttribute("messageBean"),
request);
what's causing this ClassCastException?
