Redirecting JSP or Servlet generated pages to cocoon
Hi there,
I'm looking for infos. I need to generate XML files by jsp files or
servlets (ok, basically the same), for instance becaus I need to
retrieve the xml content from a database, and want to redirect
theses generated xml pages to cocoon.
What do I have to do? Is there an how-to or article?
Thanks in advcance,

Re: Redirecting JSP or Servlet generated pages to cocoon
Posted by Kuntal Trivedi <ku...@tatainfotech.com>.
I'm using JRun on IIS, and Cocoon 1.5
I want to know where to place the URLProducer.class file in the JRun
directory.
I placed it in the jrun/jsm-default/classes , jrun/classes directory but no
luck!
Do I specify the package name in the cocoon.prperties file as
producer.type.XXX=org.apache.cocoon.producer.XXX
or just
producer.type.XXX=XXX
Either way, i get an error saying that it cannot find the class file
Please, can someone help me out
Also, what processing instruction should the xml file contain in order to be
able to use URLProducer
<?cocoon-....?>
Thanks

Re: Redirecting JSP or Servlet generated pages to cocoon
Posted by Steve Belt <sb...@VELOS.COM>.
Its so exciting when I can contribute, rather than always asking questions!
I was tasked with the same project.
1. I created a servlet which would take select statement parameters, and
return the results in .XML.
2. Created a "URL Producer" (see docs on producers) which would access the
URL, get the XML, combine it with the XSL, then return HTML to the client.
Here is the code I used for the URL Producer
To use it, pass the url which provides the xml source as a parameter called
xmlSource.
For example, in my setup, I call:
http://www.myserver.com/apage.xml?producer=URLProducer&xmlSource=http://www.
client.com/tablevalues?table_name=client_table
Please feel free to modify this. I am a "hobbyist" programmer, so I am sure
this could be improved.
(note: Remember to define the producer in the .conf file)
<begin>
package org.apache.cocoon.producer;
import java.io.*;
import java.net.*;
import java.util.*;
import javax.servlet.http.*;
import org.apache.cocoon.*;

/**
* This class implements the producer interface in order to produce a

*
