                               java.lang.reflect.Method actualMethod,
                               java.lang.reflect.Method proceed,

writeExternal

public void writeExternal(java.io.ObjectOutput out)
                   throws java.io.IOException

When serialized, first try container provided failover service. If the failover service does not handle the actual instance, the default behavior is: 1. If actual object is serializable, then serialize it directly. 2. If not, serialize the DUMMY_STRING.

writeExternal in interface java.io.Externalizable

Throws:

java.io.IOException

readExternal

public void readExternal(java.io.ObjectInput in)
                  throws java.io.IOException,
                         java.lang.ClassNotFoundException

When deserialized, first try container provided failover service. If the failover service does not handle the actual instance, the default behavior is: 1. Read the object from the stream, 2. If the object is renote ejb stub, reconnect it. 3. if the object is DUMMY_STRING, invoke ResourceBean.getActualInstance to get a new instance of the resource.
