I generated a CRUD app using the latest generator (Hibernate Tools 3.2.0 beta 6).
Then I had to change some types in the Entity. eg: I changed my "orderDate" field from Serializable to java.util.Date, since Oracle holds SYSDATE for that column. (I also changed a BigDecimal field to Double which led me to the very same problem posted here)
private Date orderDate;
java.lang.NoSuchMethodError: com.example.order.Orders.getOrderDate()Ljava/io/Serializable; at com.example.order.OrdersFinderBean.executeQuery(OrdersFinderBean.java:73) at com.example.order.OrdersFinderBean.findFirstPage(OrdersFinderBean.java:125) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:112) at org.jboss.ejb3.interceptor.InvocationContextImpl.proceed(InvocationContextImpl.java:166) ... 113 more
