public abstract class ForwardTransactionBean

extends java.lang.Object

implements ForwardTransaction

This class defines the basis of the ForwardTransaction session EJB implementation. It provides a method that allow requests to be forwarded from the store. This class will send data to a servlet that will release requests from the store at a specified rate.

Method Detail

forwardAll

public DataPacket forwardAll(java.lang.String threadName)
                      throws java.rmi.RemoteException,
                             ProcessingErrorException

This method will forward all requests in the queue. It will terminate when the queue is empty or if the queue goes offline

Specified by:

forwardAll in interface ForwardTransaction

Parameters:

threadName - the name to be given to the forwarding thread

Returns:

a DataPacket containing the result of the operation

Throws:

java.rmi.RemoteException

ProcessingErrorException

forwardAll

public DataPacket forwardAll(java.lang.String threadName,
                             int delay)
                      throws java.rmi.RemoteException,
                             ProcessingErrorException

This method will forward all requests in the queue. It will terminate when the queue is empty or if the queue goes offline

Specified by:

forwardAll in interface ForwardTransaction

Parameters:

threadName - the name to be given to the forwarding thread

delay - the time to wait between forwarding transactions in milliseconds

Returns:

a DataPacket containing the result of the operation

Throws:

java.rmi.RemoteException

ProcessingErrorException

forwardSingle

public DataPacket forwardSingle(java.lang.String threadName,
                                int sequenceNumber)
                         throws java.rmi.RemoteException

This method will forward an individual request from the queue

Specified by:

forwardSingle in interface ForwardTransaction

Parameters:

threadName - the name to be given to the forwarding thread

sequenceNumber - the sequence number of the request to process

Returns:

a DataPacket containing the result of the operation

Throws:

java.rmi.RemoteException

forwardSubset

public DataPacket forwardSubset(java.lang.String threadName,
                                java.util.SortedSet transactions,
                                int delay)
                         throws java.rmi.RemoteException

This method will forward a subset of the store.

Specified by:

forwardSubset in interface ForwardTransaction

Parameters:

threadName - the name to be given to the forwarding thread

delay - The number of requests to forward per second, -1 for no delay

Returns:

a DataPacket containing the result of this operation

Throws:

java.rmi.RemoteException

setMonitorStatus

public DataPacket setMonitorStatus(int delay)

This method will set the status of the host monitor. This method assigns the rate parameter as the number of milliseconds to delay between each try to forward a request to the store. If this is set to -1 then the monitor is suspended

Specified by:

setMonitorStatus in interface ForwardTransaction

Parameters:

delay - the number of milliseconds to delay for

Returns:

a DataPacket containing the result of this operation

Throws:

java.rmi.RemoteException
