Re: Loading a new portlet in Jetspeed 2 -- jetspeed-portlet.xml?

Scott T. Weaver Thu, 21 Oct 2004 10:38:03 -0700

There is alrady one person on the list, Randy Walter, who already has a J2 based portal in its testing phases. I have a J2-based portal project scheduled to go live the second week of November. So IMO I would go with J2.

Scott,
Thanks very much for you help.  I'm off and exploring portlets according to
168.  My next step is to plug in an existing Struts app we developed.  Looks
like you have already tackled integrating a Struts app.
We are planning on deploying a system in April 2005.  Do you think it is a
good idea for us to be working with Jetspeed2 now instead of Jetspeed1 +
Fusion?  With the significant re-architecture you are doing in Jetspeed2 it
seemed better to start with Jetspeed2 if we can.

Doug,
I see your problem right off. You need to change the the name of your portlet to:
<portlet-name>DougsFirst</portlet-name>
Redploy and it should work.
Look at point 4 on
http://wiki.apache.org/portals/Jetspeed2/DeployingCustomPortlets.  It
specifies that the value after the "::" needs to match the value in
<portletName> not the portlet-id attribute.
HTH,

I have Jetspeed 2 built and running using the following environment:
Tomcat 5.0.28
MySQL 4.0.17
I'm trying to deploy my first portlet using the instructions at http://wiki.apache.org/portals/Jetspeed2/DeployingCustomPortlets. When I deploy the portlet, Jetspeed goes through the hot deploy sequence. Here
is
my output:

Do I need to package my portlet with a jetspeed-portlet.xml deployment
descriptor?
nope. Only if you want to use extend the meta-data or access Jetspeed Portlet Services directly.
When I view the Jetspeed main page, I get the following error below in the
new portlet window.
Could you please post your portlet.xml?
Thanks for the help.  I'm looking forward to getting more involved in the
Jetspeed2.
