getServerHostName

public String getServerHostName()
                         throws Exception

A free form String identifier for this delegate invoker, can be clustered or target node This should evolve in a more advanced meta-inf object.

This will return the host supplied by the invoker locator if locator is not null. Otherwise, if the locator is null, will return null.

Specified by:

getServerHostName in interface Invoker

Throws:

Exception

invoke

public Object invoke(Invocation invocation)
              throws Exception

Description copied from interface: Invoker

The invoke with an Invocation Object.

the delegate can handle network protocols on behalf of proxies (proxies delegate to these puppies). We provide default implemenations with JRMP/Local/Clustered invokers. The delegates are not tied to a type of invocation (EJB or generic RMI).

Specified by:

invoke in interface Invoker

Parameters:

invocation - A pointer to the invocation object

Returns:

Return value of method invocation.

Throws:

Exception - Failed to invoke method.

writeExternal

public void writeExternal(ObjectOutput out)
                   throws IOException

Externalize this instance and handle obtaining the remoteInvoker stub

Specified by:

writeExternal in interface Externalizable

Throws:

IOException

readExternal

public void readExternal(ObjectInput in)
                  throws IOException,
                         ClassNotFoundException

Un-externalize this instance.

Specified by:

readExternal in interface Externalizable

Throws:

IOException

ClassNotFoundException
