Re: Unable to trace

Related to my previous post here, I have a simple piece of code in a servlet:

HttpServletRequest request = RequestData.getRequest();
HttpServletResponse response = RequestData.getResponse();
request.getRequestDispatcher("/something").forward(request, response);

The last line of which throws an error (below) which I am unable to trace further from this line in the stack. The error is :

javax.el.ELException: Cannot convert beta of type class java.lang.String to class com.cblnet.web.data.Env

and com.cblnet.web.data.Env is:

public enum Env {
     local,
     mirror,
     production;
}

But if you look at the stack trace, below (the last line in it is the last line in my simple three lines of code, the request.getRequestDispatcher().forward() ) I have no way to trace what is causing this -- can anyone shed any light here for me on how to track down this frustrating offender? Thanks in advance, RVic
