Thanks for the suggestion, Peter, but unfortunately it doesn't seem to have solved my problem. As per the other forum thread, I removed the \$ combination from the .jsp files (accountList.jsp, atmAck.jsp and transferAck.jsp), recompiled and redeployed, but I still get the same error. Starts with the java.lang.NoClassDefFoundError in CustomerControllerHome.create(), and further down the stack trace there is a Null Pointer Exception on CustomerBean.getAccounts().
