> We have a stateless session bean that contains a "remove(...)" method that takes in a specific type of array as a parameter. It seems that the EJBObjectProxyHandler confuses this custom business method with the Entity Bean "remove(...)" method. Once the logic sees that a method called "remove" is being called, it assumes that it is a "special" method instead of a business method. Here is a stack trace up to the point where this piece of logic occurs:
> {panel}
> Thread [http-80-3] (Suspended)
> StatelessEjbObjectHandler(EjbObjectProxyHandler)._invoke(Object, Class, Method, Object[]) line: 62
> StatelessEjbObjectHandler(BaseEjbProxyHandler).invoke(Object, Method, Object[]) line: 320
> Jdk13InvocationHandler.invoke(Object, Method, Object[]) line: 49
> $Proxy173.remove(FcModelKey[]) line: not available
> FCRemoveTest.test() line: 75
> ....
> {panel}
> The following code in the EjbObjectProxyHandler looks up the name of the method from the dispatch table and sees that it is a "special" method name. However, this really only applies to Entity beans and not Session Beans. Therefore, case 4 is executed, and the StatelessEjbObjectHandler.remove(...) method is called, which is empty and only returns null.
> {code}
> Integer operation = (Integer) dispatchTable.get(m.getName());
> if (operation == null) {
> retValue = businessMethod(interfce, m, a, p);
> } else {
> switch (operation.intValue()) {
> case 1:
> retValue = getHandle(m, a, p);
> break;
> case 2:
> retValue = getPrimaryKey(m, a, p);
> break;
> case 3:
> retValue = isIdentical(m, a, p);
> break;
> case 4:
> retValue = remove(interfce, m, a, p);
> break;
> case 5:
> retValue = getEJBHome(m, a, p);
> break;
> case 6:
> retValue = getEJBLocalHome(m, a, p);
> break;
> default:
> throw new RuntimeException("Inconsistent internal state");
> }
> }
> return retValue;
> {code}
> We have not run into this problem with JBoss and Weblogic. I do not believe having a method called "remove" on a Stateless Session bean is in violation of any spec, so this should work.
