Here is what I did. 1) Clean installation of JBossAS 4.0.4 and Portal 2.4GA. 2) Brought it up for the first time. Browsed to the portal home page. 3) Downloaded the JSP hello world portlet, compiled, deployed hte war file, saw the deployment ack in the console: 13:08:28,737 INFO [TomcatDeployer] deploy, ctxPath=/helloworldjspportlet, warUr l=.../tmp/deploy/tmp44829helloworldjspportlet-exp.war/ 4) Hit refesh on the browser, no hello portlet. 5) Logged in as 'user' (the portal comes configured with two login ids: 'user', 'admin'; the passwords are the same as the login id), still no hello portlet. 6) Logged out, suddenly the hello portlet shows up. Try those steps. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3971383#... Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&a...
