After following the install directions for the Java Pet Store demo, I have been unable to test it when accessing the site. The problem I run into, is that when I access the site, I get an error in the browser saying: Error: The User ID you selected is already in use. Please go back to the previous screen using the 'Back' button on your browser and select a different User ID. This is from the first time I try to access the demo. when I shutdown the server I also get an error message: Error serializing bean: com.sun.estore.contol.ejb.StateMachine in the terminal window. Has anyone else run into a similar problem. Any help would be appreciated. Thanks James Hays
