So here I am again with a new Problem. After the logon I get an Exception from the CustomerBEan: Your request cannot be completed. The server got the following error: javax.servlet.jsp.JspTagException: javax.servlet.jsp.el.ELException: An error occurred while getting property "accounts" from an instance of class com.sun.ebank.web.CustomerBean --> Do I guess right that I have a problem with my Database Cofigurations? Has anyone encountered a similar problem or has an idea what might went wrong? THX in advance View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4104558#...
