okay - did some trawls through other stuff and found references to problems like mine relating to application.xml see http://in.relation.to/Bloggers/JBossTools210CR1Released i stopped eclipse and overlaid the wtp2.02 patch then uploaded to latest jboss tools 2.1 CR1 dev patch and restarted. reedited my application.xml to drop the module/jar references as it says, cleaned rebuilt and relaunched - still got one glitch - it didnt seem to deploy the jboss-seam.jar - hopever - copied that in by hand and deployer picks that up and it then deploys. still get errors with undeploy (moans about no application.xml - but that doesnt seem to matter - and i can then proceed again. this still feels a little cludgy - and not quite there yet - but i can get started again i think.
