Forward to URL that contains parameters

[forrozeiro]

Hi,

Please, consider the following pages

test.jsp
% pageContext.forward( "test2.jsp?bla=2" ); %

test2.jsp
html body
%= request.getParameter( "bla" ) %
/body /html

When I call test.jsp, using JRun, I get "null". When I do the same call, using Tomcat, I get "2". Which one is right, Tomcat or JRun ? According to JSP specifications, should a forward of a request add in that request the URL's parameters ?

Thank you in advance,
forrozeiro.

The preferred way of forwarding in a JSP is:

<jsp:forward page=&quot;test2.jsp&quot;>
   <jsp:param name=&quot;bla&quot; value=&quot;2&quot; />
</jsp:forward>

One thing to note: The response can not be commited before the forward is sent. If it is then you will recieve an IllegalStateException. This also means that you must be very careful when using <jsp:forward> from an unbuffered JSP page.

As for your actual question, the functionality of Tomcat directly represents the JSP specification. Tomcat is the official reference implementation for Servlets/JSP. Wushutwist

Good day,

I'm using

<jsp:forward page=&quot;Cal.jsp&quot;>
   <jsp:param name=&quot;month&quot; value=&quot;<%=m%>&quot;/>
   <jsp:param name=&quot;year&quot; value=&quot;<%=y%>&quot;/>
</jsp:forward>

inside of an if statment. The page works fine as long as the if statment is not entered, but if it is, this code is executed and the page that this code is on is party displayed, for some reasone it'll only display the first bit of the page and stops way before it gets to this code, worst of all it doesn't forward.

any ideas? Thanks
