Subject Problems with Views and redirect-to
Date Mon, 07 Apr 2003 17:58:11 GMT

Hi,

  I am developing an example of a portal using cocoon. The idea is to use
an application inside another one, in the same way as the given example of
WSProxyGenerator by Cocoon. The application that I am using is the given
example of "authentication-fw". The first change I have made in the
sitemap of this is to add the ability to return xml view. Adding a new
view in the sitemap and a label in the transformer of the pipeline that
match with 'protected'. Here is the example:

   <!-- ========================================= -->
   <!-- Form target which performs auth service   -->
   <!-- ========================================= -->
   <map:match pattern="do-login">
      <!-- try to login -->
      <map:act type="auth-login">
	 <map:parameter name="handler" value="demohandler"/>
         <map:parameter name="parameter_name"
                        value="{request-param:username}"/>
  		<map:redirect-to uri="protected" />
      </map:act>
      <!-- something was wrong, try it again -->
      <map:redirect-to uri="login"/>
   </map:match>

   <!-- ================ -->
   <!-- Protected area   -->
   <!-- ================ -->
   <map:match pattern="protected">
      <map:act type="auth-protect">
        <map:parameter name="handler" value="demohandler"/>
           <map:generate src="docs/protected.xml"/>
           <map:transform src="stylesheets/simple-page2html.xsl"/>
	   <map:transform type="encodeURL"  label="xml"/>
           <map:serialize />
      </map:act>
      <!-- something was wrong, redirect to login page -->
      <map:redirect-to uri="login"/>
  </map:match>

The problem comes when I request the 'do-login' but the returned format
that I want is XML. Here is the request:
   http://localhost:8080//cocoon/samples/authentication-fw/
   do-login?cocoon-view=xml&username=cocoon

But the response send back by cocoon is HTML.

I know that cocoon redirects the request to protected area when the
username is valid and this works, but in this redirection the request of
cocoon-view=xml has been losen and responds in HTML format.
Because of that, I can´t use the request above in the wsproxy generator.
It gives an execution error message: Invalid response - no xml.

Does anybody know how to resolve this problem?

Thanks in advanced.
