your JSP cannot be compiled, probably because you did not import the taglibs correctly or because you are using the wrong (or no) namespace for the associated tags
does the JSP page show when you do not precompile and run your webapp ?
post your JSP here to make sure there is no syntax error
there is no need to go into the JspC source :-)
if you're not sure about the JSP code, let an IDE check it for you
