Problem using xsp: "Undefined variable or class name: request"

[vupt <vu...@yahoo.com>]

Hi,

I am having a problem generating an XSP page. I would
like to have a function that
returns a string based on a request parameter. If
anyone can point out my error,
I would be very grateful. 

When I run my example, I obtain this error:

java.lang.Exception: XSP Java Compiler: Compilation
failed for _clean_page.java
25: Undefined variable or class name: request
          String
vals[]=request.getParameterValues(name);
                        ^
1 error

org.apache.cocoon.processor.xsp.language.java.XSPJavaProcessor.compile(Compiled
Code)

	at
org.apache.jserv.JServConnection.run(JServConnection.java:188)
	at java.lang.Thread.run(Thread.java:479)

Here is the file that causes the error.
