public class LocalStatelessSessionProxyFactoryBean
- extends LocalSlsbInvokerInterceptor
- implements org.springframework.beans.factory.FactoryBean<java.lang.Object>, org.springframework.beans.factory.BeanClassLoaderAware
Convenient FactoryBean
for local Stateless Session Bean (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 LocalSlsbInvokerInterceptor 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).

LocalStatelessSessionProxyFactoryBean
public LocalStatelessSessionProxyFactoryBean()
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 local component interface.
Using a business methods interface is a best practice when implementing EJBs.
- Parameters:
businessInterface
- set the business interface of the EJB
getBusinessInterface
public java.lang.Class getBusinessInterface()
- Return the business interface of the EJB we're proxying.
setBeanClassLoader
public void setBeanClassLoader(java.lang.ClassLoader classLoader)
- Specified by:
setBeanClassLoader
in interface org.springframework.beans.factory.BeanClassLoaderAware
afterPropertiesSet
public void afterPropertiesSet()
throws javax.naming.NamingException
- Description copied from class:
AbstractSlsbInvokerInterceptor
- Fetches EJB home on startup, if necessary.
- Specified by:
afterPropertiesSet
in interface org.springframework.beans.factory.InitializingBean
- Overrides:
afterPropertiesSet
