Beginer XSP question 

Hi,

I have the following XSP page:

<?xml version="1.0" encoding="ISO-8859-1"?>
<?cocoon-process type="xsp"?>
<?cocoon-process type="xslt"?>
<?xml-stylesheet  href="frames2.xsl" type="text/xsl"?>


<xsp:page language="java"
xmlns:xsp="http://www.apache.org/1999/XSP/Core">
       
       <xsp:logic>
          
           HttpSession session=request.getSession(true);
           String done=(String)session.getValue("file");          
             
        </xsp:logic>
        <session><xsp:expr>done</xsp:expr></session>
    
  
</xsp:page>


When i call the page i get this error.
java.lang.Exception: XSP Java Compiler: Compilation failed for
_frames.java
25: Undefined variable or class name: request
           HttpSession session=request.getSession(true);
                               

I know that probably is a stupid question but i feel losed and i do not
know whwt i am doing wrong. 

Thanks in advance.

<xsp:logic> elements that appear outside of the root XSP node (your example
doesn't have an xsp root node) are class variables outside the scope of the
request and session objects.  You need to do something like this:

<xsp:page language="java"
xmlns:xsp="http://www.apache.org/1999/XSP/Core">
       
    <document>
       <xsp:logic>
          
           HttpSession session=request.getSession(true);
           String done=(String)session.getValue("file");
             
        </xsp:logic>
        <session><xsp:expr>done</xsp:expr></session>
    </document >
  
</xsp:page>


This will work. 

Mike

Hi,

I had the same error some time ago.

you will have to place your <xsp:logic> block into one of your xml tags:

Like this:

<?xml version="1.0" encoding="ISO-8859-1"?>
<?cocoon-process type="xsp"?>
<?cocoon-process type="xslt"?>
<?xml-stylesheet  href="frames2.xsl" type="text/xsl"?>
 
<xsp:page language="java"
 xmlns:xsp="http://www.apache.org/1999/XSP/Core">
       <session>
         <xsp:logic>
           
            HttpSession session=request.getSession(true);
            String done=(String)session.getValue("file");          
              
         </xsp:logic>
	 <xsp:expr>done</xsp:expr>
       </session>
</xsp:page>
