Modifier and Type | Method and Description |
---|---|
protected abstract Object |
doInvoke(MethodInvocation invocation)
Perform the given invocation on the current EJB home.
|
protected Method |
getCreateMethod(Object home)
Check for EJB3-style home object that serves as EJB component directly.
|
Object |
invokeInContext(MethodInvocation invocation)
Fetches an EJB home object and delegates to
doInvoke . |
protected boolean |
isConnectFailure(RemoteException ex)
Determine whether the given RMI exception indicates a connect failure.
|
protected boolean |
isHomeRefreshable()
Return whether the cached EJB home object is potentially
subject to on-demand refreshing.
|
protected Object |
lookup()
This overridden lookup implementation performs a narrow operation
after the JNDI lookup, provided that a home interface is specified.
|
protected Object |
newSessionBeanInstance()
Return a new instance of the stateless session bean.
|
protected Object |
refreshAndRetry(MethodInvocation invocation)
Refresh the EJB home object and retry the given invocation.
|
protected void |
removeSessionBeanInstance(EJBObject ejb)
Remove the given EJB instance.
|
void |
setHomeInterface(Class<?> homeInterface)
Set a home interface that this invoker will narrow to before performing
the parameterless SLSB
create() call that returns the actual
SLSB proxy. |
void |
setRefreshHomeOnConnectFailure(boolean refreshHomeOnConnectFailure)
Set whether to refresh the EJB home on connect failure.

public void setHomeInterface(Class<?> homeInterface)
create()
call that returns the actual
SLSB proxy.
Default is none, which will work on all J2EE servers that are not based
on CORBA. A plain javax.ejb.EJBHome
interface is known to be
sufficient to make a WebSphere 5.0 Remote SLSB work. On other servers,
the specific home interface for the target SLSB might be necessary.
public void setRefreshHomeOnConnectFailure(boolean refreshHomeOnConnectFailure)
Can be turned on to allow for hot restart of the EJB server. If a cached EJB home throws an RMI exception that indicates a remote connect failure, a fresh home will be fetched and the invocation will be retried.
