Subject RE: Can´t get Request from an Action
Date Tue, 14 May 2002 13:20:25 GMT
Hi Markus,

sorry, maybe I misunderstood you.

Please try to set the attribute in your action as follows:

  Request theRequest = (Request)aObjectModel.get(Constants.REQUEST_OBJECT);
  if (theRequest != null)

Whereby "aObjectModel" comes into the action as an argument - maybe this
name is different in your action.

Best regards
- Volker -

Subject: Can´t get Request from an Action

Hello Folks,

I added a self-developed action to org/apache/cocoon with a path from there
like ask/auth. Under auth I have created a servlet called You
guessed!.. I am trying to create a login-action for internal use (I know
there is a sample, but that doesn´t fit our needs).

The Login-Servlet gives me a Map back (nothing new) and it sets an attribute
to a Request like ...


as in the docs from Cocoon!!! "Creating and Using Actions".

The value of the Map is read successfully in the sitemap.xmap, but the
request values can't be read out within an xsp-page. Got only null.

What's wrong?
package org.apache.cocoon.ask.auth;

import org.apache.avalon.framework.parameters.Parameters;
import org.apache.avalon.framework.thread.ThreadSafe;
import org.apache.cocoon.acting.AbstractAction;
import org.apache.cocoon.Constants;
import java.util.Map;
import java.util.HashMap;
import org.apache.cocoon.environment.*;
import org.xml.sax.EntityResolver;

public class Login extends  AbstractAction
     implements  ThreadSafe {

  public Map act (Redirector   redirector,
                  SourceResolver resolver,
                  Map     objectModel,
                  String   source,
                  Parameters   params
   ) {

    Map  sitemapParams  = new HashMap();
      sitemapParams .put ("authArt", "login");

    Request  request = (Request) objectModel.get (Constants.REQUEST_OBJECT);
      request .setAttribute ("hello", "world");

   return sitemapParams;
<para><xsp-request:get-attribute name="hello"/></para>
The rest of xsp-page is correct.
 <p><xsl:value-of select="//para"/></p> <br/>
... Rest OK.
     <map:action name = "xifs-login"
        src  = "org.apache.cocoon.ask.auth.Login"/>
... within a pipeline!!!
<!-- SERVLETS -->
  <map:match pattern="auth/**">
      <!-- Performe login ... -->
      <map:act type="xifs-login">

    <map:generate type="serverpages" src="../xsp/login.xsp"/>
    <map:transform src="../styles/login.xsl"/>


      <!-- If all fails ...-->
      <map:redirect-to uri="../welcome"/>



Thanks for any help.

Regards Markus
