[jboss-user] [EJB 3.0] - JspTagException in links.jsp and $Proxy97 not found running

[cscs010]

Hi everyone,

I am relatively new to JBOSS (4.0.5) and am trying to run the DukesBank example on a SUSE LINUX system (running on z/os).
i finally got the example working on WINDOWS after a few modifications, but I never encountered this particular problem on Windows and cannot
find anything about it as pertains to the DukesBank example, although i saw that there might be some type of jndi error.
 the HSQL database looks okay on the Linux system and as I stated, all is working fine on Windows.

after i sign on with id=200, password=j2ee, i get the following error in the browser about links.jsp. 
      
 Your request cannot be completed. The server got the following error: 
javax.servlet.jsp.JspTagException: Exception in JSP: /template/links.jsp:33 30: 31: 32: 33: 34: 35: 36: Stacktrace: 

i did not change anything in links.jsp - these are the tags provided:

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt" %>
<jsp:useBean id="customerBean" class="com.sun.ebank.web.CustomerBean" scope="request"/>
<jsp:setProperty name="customerBean" property="customer" value="${pageContext.request.userPrincipal.name}"/>
<c:set var="accounts" value="${customerBean.accounts}" />
<c:forEach items="${accounts}" begin="0" end="0" var="ad">
<c:set var="accountId" value="${ad.accountId}" />
</c:forEach>

however, the log also shows that $PROXY97 cannot be found.
