Bug in Duke's Bank example in the J2EE 1.4 Tutorial update 4, and workaround

There is a bug in NextIdBean.ejbCreate() in update 4 of the J2EE 1.4 Tutorial.

public Object ejbCreate() throws CreateException { return null; }

should be:

public String ejbCreate() throws CreateException { return null; }

This bug doesn't show up when using J2SE 5, only when using J2SE 1.4. J2SE 5 allows subclasses to have different return types. Look for a bug-fix update to the J2EE 1.4 Tutorial within a few weeks.

Even with the recommended changes "Dukes Bank application" returns the following error: Your request cannot be completed. The server got the following error: javax.servlet.jsp.JspTagException: An error occurred while getting property "accounts" from an instance of class com.sun.ebank.web.CustomerBean Iff the CustomerHackFilter.class of http://blogs.sun.com/roller/page/ievans/20050322#bug_in_duke_s_bank is also installed in the WAR-File, everything works.

Hi Johannes. We're looking into this problem. I can reproduce the bug (which never showed up during development & testing back in December--hmm). Stay tuned. -ian
