Hi thank you for the reply. I am able to work with Source Writing
Transformer. But I have a new issue; how to redirect to another page after
using Source Writing Transformer or any other transformer or generator and
so on.
 

Cocoon is not intended to be used in that way. Once a pipeline has been 
build, and has started being processed, it is not possible to redirect 
it to another place - the pipeline has to complete.

There's three ways to achieve what you're talking about:
1) Send a page with a <meta http-equiv="refresh" 
content="0;http://server/newpage"/> entry in <head/>
2) Better - transform the results of the SWT into an HTML page that 
makes sense to its viewer.
3) Use flow - don't use SWT, just use some Javascript to write to your 
source, then you can redirect wherever you like.

Thanks,

I assume you have looked at the examples at
cocoon/docs/userdocs/components/transformers/sourcewriting-transformer.html
Here's what we use (under Cocoon 2.1.2).
In the sitemap:
...
   <map:view name="source" from-label="source">
     <map:transform type="write-source">
       <!-- <map:parameter name="serializer" value="text" /> --><!--
unnecessary -->
     </map:transform>
     <map:transform src="transforms/post-write-source.xsl" />
     <map:serialize/>
   </map:view>
...
     <map:match pattern="*/*/cell/*/s*/*.xsl"> <!-- Stylesheet  to generate
Row 5 source code -->
       <map:generate src="cocoon:/base/{1}/{2}/{3}/s{4}" label="raw" />
       <map:transform src="archFrame/s{4}/{3}/{5}.xsl" label="source"> <!--
here -->
         <map:parameter name="system" value="{1}" />
       </map:transform>
       <map:transform src="transforms/source.xsl" label="raw2">
         <map:parameter name="system" value="{1}" />
         <map:parameter name="state" value="{2}" />
       </map:transform>
       <map:serialize type="html"/>
     </map:match>
So if the parameter ?cocoon-view=source is included on the request URL,
the output of the transform labeled "here" goes to the
SourceWritingTransformer;
otherwise it goes to a different transformer (post-write-source.html)
that formats it as human-friendly HTML.
An example of the input to the SourceWritingTransformer:
