JetSpeed VelocityPortlet extension

[Ashwin Jayaprakash <as...@rediffmail.com>]

Is there a way to have a custom Velocity Portlet where
we can put some objects into the Context and so can be
accessed from the Velocity Template?

Apparently, overriding the "getContent(RunData)" and
pushing some objects into it by doing this - (see code
below), does not work, as the populateContext id
overwritten by the parent i.e VelocityPortlet. So, I
ended up copying the entire code of
VelocityPortlet.java and adding a few lines of my own
code. Is there another way to do it?

//-------- start ------------------
     public ConcreteElement getContent( RunData rundata )
     {
         Context context = TurbineVelocity.getContext();
         context.put( "myname", "Ashwin Jayaprakash" );
         context.put( "dob", "Aug 24, 1996" );
         context.put( "site", "www.javaforu.com" );

         TurbinePull.populateContext(context, rundata);

         return super.getContent( rundata );
      }
//-------- end ------------------


Thanks,
Ashwin.

You don't neeed to extend the VelocityPortlet, simply do the following:
- extend 
org.apache.jetspeed.modules.actions.portlets.VelocityPortletAction to
   write you own FooAction.
- define at least the buildNormalContext() of this FooAction to fill up 
the Portlet context
   with your own variables (if you have defined Turbine tools, they'll 
automatically
   available in your portlet).
- write your template(s) for this portlet, eg foo.vm
- in the registry, associate your Action and base template to the 
VelocityPortlet:
 
    <portlet-entry name="Foo" type="ref"  parent="Velocity">
        <meta-info>
            <title>Foo</title>
            <description>My Foo portlet</description>
        </meta-info>
        <parameter name="template" value="foo"/>
        <parameter name="action" value="portlets.FooAction"/>
        <media-type ref="html"/>
    </portlet-entry>

And you're set !
