Subject Using an action correctly?
Date Wed, 29 Jan 2003 14:59:42 GMT
Hi,

I have written an action and compiled it successfully. I put it in the
cocoon/WEB-INF/lib folder as a jar:

package test.acting;

import java.util.Map;
import java.util.HashMap;
import org.apache.avalon.framework.parameters.Parameters;
import org.apache.cocoon.acting.AbstractAction;
import org.apache.cocoon.environment.Request;
import org.apache.cocoon.environment.SourceResolver;
import org.apache.cocoon.environment.Redirector;
import org.apache.cocoon.environment.ObjectModelHelper;
import org.xml.sax.EntityResolver;


public class XslSelection extends AbstractAction {

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

    Map results = new HashMap();
    Request request = ObjectModelHelper.getRequest(objectModel);

    String report_id = request.getParameter("report_id");
    String service_id = request.getParameter("service_id");

    // Now choose the suitable XSL for the output
    if(report_id.equals("16"))
      results.put("report_16","report_16");
    else if(report_id.equals("17") && service_id.equals("GSM"))
      results.put("report_17GSM","report_17GSM");
    else if(report_id.equals("17") && !service_id.equals("GSM"))
      results.put("report_17","report_17");
    else if(report_id.equals("19"))
      results.put("report_19","report_19");
    else if(report_id.equals("18"))
      results.put("report_18","report_18");
    else
      results.put("error","error");

    return results;
  }
}


In the sitemap I "import" it as follows.
 ...
<map:actions>
      <!-- here is the class defined that is used for choosing the right
xsl for the output -->
      <map:action name="xslSelect" src="test.acting.XslSelection"/>
                ...
</map:actions>


Thats how I use it in the sitemap:
...
<map:match pattern="blabla">
            <map:generate src="sampleoutput.xml"/>
            <map:act type="xslSelect">
                   <map:transform src="stylesheets/{results}.xsl"/>
                   <map:serialize type="fo2pdf"/>
            </map:act>
 </map:match>
...

But I only get the error that cocoon can't find the page (Resource not
found). Invoking the different stylesheets "manually" is no problem, but
using the action.
Since it is my first action, I don't know where to look for the error.

Another question. Can't I just give back a String? My XSLs are called
report_16.xsl, report_17.xsl, report_18.xsl, report_19.xsl, error.xsl
