I'd really like to know how those people who got Duke's Bank working with JBoss 4.0.5 did it. I'm using 4.0.5 on Windows with the IBM Java 5 JDK. I have set the jboss.home value to the location of my JBoss installation, which is C:/jboss/jboss-4.0.5.GA. I have executed all the steps of the tutorial from the first ANT task, compile, through creating and populating the db tables, up to the deploy task. I did find one discrepancy between the tutorial and JBoss 4.0.5. In the hsqldb-ds.xml file, the mBean for accessing the db in server-mode (the second last mBean in the file) had an extra attribute not shown in the tutorial. This was the "BindAttribute", which I set to "localhost" as in the <connection-url> from the top of the file. But in all other respects I have followed the tutorial exactly. However, when I log into the application through my browser, entering the designated username ("200") and password ("j2ee"), I get an error. On screen it is listed as a JspTagException in JSP /template/links.jsp:33 30. But the logs indicate the problem really starts with a NoClassDefFound exception when trying to call ejbCreate() for CustomerControllerBean. I don't get it. I haven't hacked the build file. I haven't hacked the server (I started with a clean installation, running the default server as per the tutorial). I haven't hacked the tutorial sources, other than to copy the JBoss files in on top of the original Sun ones. Nor have I hacked the generated .EAR file to remove a .jar or change its visibility. Can any of those who have got this tutorial to work suggest what is going wrong here? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4053481#...
