Did you run the "ant deployPortletApp" ant target, or did you just copy the war file into webapps directly? copying directly will not work. You must run the uPortal tool for deploying the portlet web applications.

Hi,

I set up uPortal-3.0.1-quick-start up and running, and I use netbean ide 6.1 to create a helloworld portlet. I copy the HelloWorld.war
C:\uPortal-3.0.1-quick-start\apache-tomcat-5.5.23\webapps
Then restart uPortal,

I created a new channel to publish this portlet by portlet manager. Here is my setting

But, after I subscribe it, I have the following error
Channel ID:
   n85

Message:
   Message not available

Error type:
   Channel failed to initialize (code 2)

Problem type:
   General rendering problem

Error message
Content was written to response during loading of portlet window 'PortletWindowImpl[portletWindowId=16.n85,contextPath=/HelloWorld,portletName=HelloWorld,windowState=normal,portletMode=view,expirationCache=<null>,requestParameters={}]' with [channelPublishId=73, channelSubscribeId=n85, portletApplicationId=/HelloWorld, portletName=HelloWorld, user=admin]. Response Content: The requested resource (/HelloWorld/PlutoInvoker/HelloWorld) is not available


What is it wrong?


Thanks,

Edward
