It is possible to refresh Portlets ?
Hi all,
i try to develop an portlet which is usable like the windows explorer. For
that i create an AbstractPortlet and using the ECS to define the layout. The
problem i have is, that i am forced to use actions on the Elements (the
folder images).
To realize that actions i can't use real JAVA-Actions like the MouseListener
because they are ignored by the Turbine-Engine. Now i have tried to use
JAVA-Skript elements like onMouseOver to realize some actions. My idea is to
force jetspeed by this action to refresh the page, analyses the parameters
and repaint the table by using the parameters.
The refresh works, but only my portlet is not refreshed and i got the
following exception message where my portlet is:
org.apache.turbine.util.TurbineException: Error rendering Velocity template:
/controls/html/jetspeed.vm: Invocation of method 'getContent' in class
org.apache.jetspeed.portal.security.portlets.CacheableStatefulPortletWrapper
threw exception class java.util.NoSuchElementException : null
Where is my failure? Knows anybody a solution or a better way to realize
actions (perhaps execute real java actions)? In every action i must read out
some parameters and repaint the explorer-Portlet by checking these params...
Thanks in advance
Christian

RE: Replcaing the default_top with vm and jsp
Posted by Javed Mahmud <jm...@it.uts.edu.au>.
Thanks Mark,
You are right that I m trying to use JSP as default teplate.
I was not sure about the fact that only one (either JSP or Velocity) can
be used as template at a time.
Second I have tried both velocity and JSP both without changing the
property u have mentioned here. So in theory the vm file should have
worked, but it didn't.
Any help will be appreciated.
Cheers!

Hi Mark,
Apparently there was a bad entry in the JetSpeed Resources Properties
which was creating problem. I removed it and every thing was fine. And Yes
Either JSP or Velocity can be used for the templates as one of thenm can
be default template.
Thanks

If what you're trying to do is to use JSP as the default template engine,
then here's the entry in jr.props:
services.TemplateService.default.extension=jsp
If not, then please clarify your intentions.

Replcaing the default_top with vm and jsp
Posted by Javed Mahmud <jm...@it.uts.edu.au>.
Hi,
I have been looking to change the default_top and default bottom of the
JetSpeed default page.
I have been following the tutorial for the Beta 2 version(I have been told
in this list that the tutorial can work with Beta 1 version too) I have
tried to use
topnav.vm = top_default.jsp property in JetSpeedREsources.properties file
but to no avail. I have tried top.vm also but the error on the top of the
page which shows up with other things is
Error processing navigation template:/html/top.vm using module:
VelocityNavigation
The Template Locator related parameters in JR.p are :
services.TemplateLocator.classname=org.apache.jetspeed.services.template.JetspeedTemplateLocatorService
services.TemplateLocator.templateRoot=/WEB-INF/templates
services.TemplateService.default.extension=vm
And also the topnav.enable = true.
the values in TurbineResource.properties for Velocity Service
services.VelocityService.file.resource.loader.path = /WEB-INF/templates/vm
and for JSP Service is
services.JspService.templates =/WEB-INF/templates/jsp
services.JspService.buffer.size = 8192
Any help will be valuable.
Thanks

The index page or the layout which contains the Jetspeed Logo and other

I put the string <META HTTP-EQUIV=\"REFRESH\" CONTENT=0,01 >
in a get content of a portlet ,one time to force the refresh the
page,(content = specify the second after reload a page)
and remove in the the next call to the portlet.
Use a flag to verify if the string has been put in the portlet one time, to
remove it at the second call.
Is' not a elegance method but it's the only that i found.
Excuse for my bad english.

Fulcrum.properties Database entries
Posted by Javed Mahmud <jm...@it.uts.edu.au>.
hello,
I was wondering what is the use of entries for databse in
Fulcrum.properties file?
As we specify the Databse details in Torque.properties file.
Is there any special importance of specifying the details in
Fulcrum.properties file?
Thanks

I believe Struts has a tree view control.
This looks cool, not sure if its part of Jakarta Struts or add-on
http://struts.application-servers.com/tags/treeview.html
Do you know about Turbine actions in Jetspeed?
