Hi, Hopefully someone can point me in the right direction here as I think I'm in the "wood for trees zone". I have installed JBOSS JMS on an IBM System p p505 running AIX 5.3 , Java version: 1.5.0,IBM Corporation and Java VM: IBM J9 VM 2.3,IBM Corporation. I have also installed and built the J2EE tutorial Dukes Bank to "prove" the installation. Problem is I can't get it to work! I get the login screen and when I enter the user and password I get presented with this exception: 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 There are also a stream of messages appearing in the Java console windows as well of which I have included the first tranch: 09:08:12,538 ERROR [STDERR] Debug: Creating bean manager. 09:08:12,571 ERROR [STDERR] Debug: CustomerControllerBean ejbCreate 09:08:12,573 ERROR [LogInterceptor] Unexpected Error in method: public abstract

Bank and it works fine! What I have done is to itry and dentify any areas of difference between the two but there is nothing leaping out at me. I'm wondering if it is a PATH related issue (as that is what the error seems to refer to) and have made sure that I have included all the correct paths in the (hopefully) correct places but still I get the error. I am using MySQL as the database (in both places) and have made sure that all the data is set up correctly. Can someone point me in the right direction for this one please?
