Date Wed, 19 Oct 2005 07:04:12 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Cocoon Wiki" for change notification.

The following page has been changed by BertrandDelacretaz:
http://wiki.apache.org/cocoon/LogAction

New page:
Here's the code of an Action which logs a message to a specific logger. 

This can be useful to keep track of visits to certain URLs in a separate logger than the application
logger.

= Code =
{{{
package whatever.you.want;

import org.apache.cocoon.environment.SourceResolver;
import org.apache.cocoon.environment.Redirector;
import org.apache.cocoon.acting.AbstractAction;
import org.apache.avalon.framework.parameters.Parameters;

import java.util.Map;

/** An Action which simply logs a message. */

public class LogAction extends AbstractAction {
    public Map act(Redirector redirector, SourceResolver resolver, Map objectModel, String
source, Parameters parameters)
    throws Exception {
        final String msg = parameters.getParameter("msg",null);
        if(msg!=null) {
            if(getLogger().isInfoEnabled()) {
                getLogger().info(msg);
            }
        }

        // don't execute what's inside this action, it's just here to log something
        return null;
    }
}

}}}
