About vm to JSP

Hi all,
this is workable code fragment of portlet passing some data to vm-template:

//-----------------------------------------------
//rundata - RunData object
//template - String, name of vm-template ("result.vm")

Context context = TurbineVelocity.getContext();
context.put("portlet", this);

TurbinePull.populateContext(context, rundata);

ClearElement element = null;

try {

    //get data for current portlet
    if (context.get("editValue") == null) {
       //get "editValue" from initial parameter
       context.put("editValue", getPortletConfig().getInitParameter("editValue"));
    }
    if (context.get("selectValue") == null) {
       //get "selectValue" from initial parameter
       context.put("selectValue", getPortletConfig().getInitParameter("selectValue"));
    }
    if (context.get("passwordValue") == null) {
       //get "passwordValue" from initial parameter
       context.put("passwordValue", getPortletConfig().getInitParameter("passwordValue"));
    }

    //make HTML
    String templatePath = TemplateLocator.locatePortletTemplate(rundata, template);
    String s = TurbineVelocity.handleRequest(context, templatePath);
    element = new ClearElement(s);
    //doing this because setContent() is not overwriting current content.
    clearContent();
    setContent(element);
} catch (Exception e) {
    element = new ClearElement(e.toString());
}
TurbineVelocity.requestFinished(context);
 "
//-----------------------------------------------

and this is result.vm:

#if (!$editValue)
#set ( $editValue = "edit value is null" )
#end
#if (!$selectValue)
#set ( $selectValue = "select value is null" )
#end
#if (!$passwordValue)
#set ( $passwordValue = "password value is null" )
#end
    Edit value<br>
    <b>$editValue</b><br>
    Select value<br>
    <b>$selectValue</b><br>
    Password value<br>
    <b>$passwordValue</b>

And the question is: how can i create portlet passing the same data
into JSP-template? And what must be in JSP-template?

Thanks in advance.

Best regards,
 Den_M

There will be a section in Jetspeed Tutorial on JSP Portlet, hopefully by
the end of the week.
