hmm. No. Let me update the download, its not deploying as it still has the 2.0 descriptors. I'll get back to this post today when complete.
ok. Try again: http://labs.jboss.com/file-access/default/members/portletswap/downloads/portlets/framework/TapestryHelloWorld.zip
Unzip it. There will be a TapestryHelloWorld.war that you need to deploy. If it deploys successfully, you will see the Tapestry HelloWorld tab at the top of the default page.
Actually, I've given up on JBoss Portal. It takes 10-20 seconds to respond whenever you click anything on any page, and it blows up all the time - I'm still having that problem of the management portal disappearing. The only cure for this is to delete the database tables and start again. Not promising.
Plus, the documentation still sucks - where, for instance, is the explanation of how to deploy and test a portal, what is a portal instance, etc. etc. It seems to be written for people who are used to version 1, not newbies. I give up.
