What I was trying to do is use Velocity to implement the Layout for a
page and then have some Screens that are implemented in JSP and some in
Velocity.
Ok, got it. You can't mix VM & JSP this way. The code forces the
Screen & Layout to both be either JSP or VM. Seems to me that you ought
to be able to do this, but I'm not familiar enough with Turbine to know
if this is a limitation of Turbine or Jetspeed. If Turbine can support
this scenario how hard would it be to get Jetspeed to do it ?
Here's the code that's causing my scenario not to work. This is with
Jetspeed 1.5
It's in the
org.apache.jetspeed.modules.pages.JetspeedTemplatePage.doBuildAfterActio
n(RunData) method.
.....
---> This section forces the extension onto the template name.
String ext = TurbineTemplate.getDefaultExtension();
.....
if (template.lastIndexOf('.')<0)
{
template=template+"."+ext;
}
if ( logger.isDebugEnabled() )
{
logger.debug("JetspeedTemplatePage: requested template =
" + template);
}
---> This section looks up the JSP screen, no problem because it's there
// get real path now - this is a fix to get us thru 1.3a2
// when the TurbineTemplateService can locate resources by
NLS and mediatype,
// then it can be removed
String locatedScreen =
TemplateLocator.locateScreenTemplate(data, template);
data.setScreenTemplate( locatedScreen );
if ( logger.isDebugEnabled() )
{
logger.debug("JetspeedTemplatePage: calculated template
= " + locatedScreen);
}
---> This section assumes that the Layout is the same templating
technology as the screen
---> but the JSP version of the Layout isn't there so it fails returning
NULL (because I removed it)
---> which ultimately causes a null pointer exception to be thrown.
---> OR
---> It finds the wrong Layout (because I did not remove it) and
dynamically switches the Layout
---> from the VM version to the JSP version which seems to really screw
up the state of the portal from
---> that point forward
String layout = TemplateLocator.locateLayoutTemplate(data,
template);
data.setLayoutTemplate(layout);
if ( logger.isDebugEnabled() )
{
logger.debug("JetspeedTemplatePage: layoutTemplate is
finally " + layout);
}
.....
Thanks,
Tom

Subject: RE: What do you need to do to add a new screen ?
Ok, so I changed the code in left.vm to the following
Jslink.getTemplate("Page2.jsp")
This caused the template to be found but also caused left.jsp to be
rendered instead of left.vm which confuses me. I would have expected
left.vm to be rendered using velocity and for Page2 to be rendered by
JSP. What's even more weird is that the top & bottom are still
rendering top.vm & bottom.vm.
Any insight as to what I'm doing wrong ? I feel like I'm missing
something simple here.
Thanks,
Tom

David,
Thank you. The jslink example helps a lot.
The $jslink.getTemplate("Page2") is working. But I also have some
templates that are JSP. The $jslink.getTemplate() method seems to only
be finding VM templates and not the JSP templates. Is it possible to
link from a VM template such as left.vm to a JSP template ?
Thanks,
Tom

Its documented in the JetspeedLink.java interface
http://cvs.apache.org/viewcvs.cgi/jakarta-jetspeed/src/java/org/apache/j
etspeed/util/template/JetspeedLink.java?rev=1.15&view=markup
The $jslink is self-documented with examples in the "JSLink Examples"
portlet.
Add this portlet to your page with the customizer and you will see
The other variations ($clink, $link, $jlink) we tried to deprecate.
