Class RetryInterceptor

java.lang.Object
  org.jboss.proxy.Interceptor
      org.jboss.proxy.ejb.RetryInterceptor

All Implemented Interfaces:: Externalizable, Serializable

public class RetryInterceptor
extends Interceptor

An interceptor that will retry failed invocations by restoring the InvocationContext invoker. This is triggered by a ServiceUnavailableException which causes the interceptor to fall into a while loop that retries the lookup of the transport invoker using the jndi name obtained from the invocation context under the key InvocationKey.JNDI_NAME, with the additional extension of "-RemoteInvoker" if the invocation type is InvocationType.REMOTE and "-HomeInvoker" if the invocation type is InvocationType.HOME. The JNDI environment used for the lookup must be set via the setRetryEnv. Typically this is an HA-JNDI configuration with one or more bootstrap urls.
