Method Detail

getApplicationSession

javax.servlet.sip.SipApplicationSession getApplicationSession(String applicationSessionId,
                                                              long timeout,
                                                              TimeUnit unit)
                                                              throws LockTimeoutException

This method performs getSipApplicationSession but with the added timeout

Parameters:

applicationSessionId - sipapplicationsession id

timeout - timeout

unit - TimeUnit

Returns:

SipApplicationSession

Throws:

LockTimeoutException - - if the SipApplicationSession can't be retrived in <timeout>

doAction

Object doAction(String applicationSessionId,
                WlssAction action)
                throws Exception

This method allows a way to execute a WlssAction in a synchronous manner. During the execution of this method, no other thread or engine tier cluster member will be allowed access to the call-state pertaining to the SipApplicationSession with applicationSessionId. When this API is used by the applications, the container guarentees that the business logic contained within the WlssAction will be executed with a lock on the SipApplicationSession instance corresponding to the applicationSessionId.

Parameters:

applicationSessionId - id of the SipApplicationSession that needs to be updated in a transactional manner.

action - WlssAction which is passed by the application

Returns:

Returns the result of the WlssAction's run method (may be null)

Throws:

IllegalArgumentException - if applicationSessionId or action parameters were null or if callId could not be extracted from the applicationSessionId

Exception

doAsynchronousAction

void doAsynchronousAction(String applicationSessionId,
                          WlssAsynchronousAction action)

This method allows an application to access a SipApplicationSession in an asynchronous manner. This method is useful for accessing the SipApplicationSession from Web or EJB modules in a converged application. When this API is used by the above modules, the container guarantees that the business logic contained within the SipApplicationSessionAsynchronousWork will be executed in a thread-safe manner. It is upto container to decide whether the work executes locally or remotely.

Example Usage:

 
    SipApplicationSession appSession = ...;
    appSession.doAsynchronousAction(new SipApplicationSessionAsynchronousWork() {
       Serializable run(SipApplicationSession appSession) {
         // add your business logic here
         int counter = appSession.getAttribute("counter");
         ++ counter;
         appSession.setAttribute("counter", counter);
         return null;
       }
     });
 

Parameters:

action - the work to be done on this SipApplicationSession. The run method of this object contains the work (business logic) to be performed.
