Method Detail

preInvoke

public RequestCtx preInvoke(int txa)
                     throws RemoteException

preInvoke is called before any request.

Overrides:

preInvoke in class JSessionRemote

Parameters:

txa - Transaction Attribute (Supports, Required, ...)

Returns:

A RequestCtx object

Throws:

RemoteException - Thrown when the method failed due to a system-level failure.

postInvoke

public void postInvoke(RequestCtx rctx,
                       Object response,
                       boolean remove)
                throws RemoteException

postInvoke is called after any request.

Parameters:

rctx - The RequestCtx that was returned at preInvoke()

remove - TODO

response - The response that is going to be returned to the client (Needed by HA)

Throws:

RemoteException - Thrown when the method failed due to a system-level failure.

injectState

protected void injectState()

Injects the state of the bean if the cluster object id received in the request is in the current node. It extracts the object id passed through the interceptors from the request id included in the current HA context.

hasResponse

protected boolean hasResponse()

Checks if there is a response associated with the current request id

Returns:

true if the current request id have an associated response

getResponse

protected Object getResponse()

Obtain the response associated with the current request id. Returns null if there is not response associated with the current requestId IMPORTANT: This method remove the request id from the requests heap

Returns:

the response associated with the current request id
