anonymous wrote : what exactly do I need to do wih the code tags? When posting XML text or source code, please enclose the text in UBBCode "code" tags - you can do this by selecting the text and clicking the Code button above the editor window. Also, click the Preview button to ensure that the formatting is correct and the XML text shows up before posting. The original application.xml file was correct. If upgrading to 5.0.1.GA doesn't work, try this. Remove helloworld.ear from the deploy directory. Then start the app server. Once the "Started in xxx seconds" log entry appears, then copy helloworld.ear back into the deploy directory.
