Convenient FactoryBean
for remote SLSB proxies.
Designed for EJB 2.x, but works for EJB 3 Session Beans as well.
See JndiObjectLocator
for info on
how to specify the JNDI location of the target EJB.
If you want control over interceptor chaining, use an AOP ProxyFactoryBean
with SimpleRemoteSlsbInvokerInterceptor rather than rely on this class.
In a bean container, this class is normally best used as a singleton. However,
if that bean container pre-instantiates singletons (as do the XML ApplicationContext
variants) you may have a problem if the bean container is loaded before the EJB
container loads the target EJB. That is because by default the JNDI lookup will be
performed in the init method of this class and cached, but the EJB will not have been
bound at the target location yet. The best solution is to set the lookupHomeOnStartup
property to false, in which case the home will be fetched on first access to the EJB.
(This flag is only true by default for backwards compatibility reasons).
This proxy factory is typically used with an RMI business interface, which serves
as super-interface of the EJB component interface. Alternatively, this factory
can also proxy a remote SLSB with a matching non-RMI business interface, i.e. an
interface that mirrors the EJB business methods but does not declare RemoteExceptions.
In the latter case, RemoteExceptions thrown by the EJB stub will automatically get
converted to Spring's unchecked RemoteAccessException.

SimpleRemoteStatelessSessionProxyFactoryBean
public SimpleRemoteStatelessSessionProxyFactoryBean()
setBusinessInterface
public void setBusinessInterface(java.lang.Class businessInterface)
- Set the business interface of the EJB we're proxying.
This will normally be a super-interface of the EJB remote component interface.
Using a business methods interface is a best practice when implementing EJBs.
You can also specify a matching non-RMI business interface, i.e. an interface
that mirrors the EJB business methods but does not declare RemoteExceptions.
In this case, RemoteExceptions thrown by the EJB stub will automatically get
converted to Spring's generic RemoteAccessException.
- Parameters:
businessInterface
- the business interface of the EJB
getBusinessInterface
public java.lang.Class getBusinessInterface()
- Return the business interface of the EJB we're proxying.
