constructor.

Parameters:

bf - The Bean Factory

Method Detail

getSessionId

public int getSessionId()

canPassivate

public boolean canPassivate()

Returns:

true if instance can be passivated

isPassivated

public boolean isPassivated()

Returns:

true if instance has been passivated.

passivate

public boolean passivate()

Passivate this instance

pushConnectionList

public void pushConnectionList()

Set the connection list associated to the current thread with the list associated to this stateful session.

Specified by:

pushConnectionList in class JSessionSwitch

popConnectionList

public void popConnectionList()

save the current connectionList for future use (next preInvoke).

Specified by:

popConnectionList in class JSessionSwitch

setConnectionList

public void setConnectionList(java.util.List cl)

Save the Connection List after a create method.

enlistConnections

public void enlistConnections(javax.transaction.Transaction tx)

enlist all connection of the list

Specified by:

enlistConnections in class JSessionSwitch

delistConnections

public void delistConnections(javax.transaction.Transaction tx)

delist all connections of the list

Specified by:

delistConnections in class JSessionSwitch

timeoutExpired

public void timeoutExpired(java.lang.Object arg)

The session timeout has expired

Parameters:

arg - Not Used.

getStatefulContext

public JStatefulContext getStatefulContext()

Returns:

the StatefulContext (for passivation)

getICtx

public JSessionContext getICtx(javax.transaction.Transaction tx)

At each business method, get a BeanContext to run it

Specified by:

getICtx in class JSessionSwitch

Parameters:

tx - The Transaction Context

Returns:

The Session Context

bindICtx

public void bindICtx(javax.transaction.Transaction tx,
                     JStatefulContext bctx)

At each create, bind the Context to the transaction

Parameters:

tx - The current Transaction Context

bctx - The Context to bind

releaseICtx

public void releaseICtx(RequestCtx req,
                        boolean discard)

Release the Context after use.

Specified by:

releaseICtx in class JSessionSwitch

Parameters:

discard - if true, instance must be discarded

noLongerUsed

public void noLongerUsed()

This Session is no longer used: - unexport Remote Object - return the Session in the pool

Specified by:

noLongerUsed in class JSessionSwitch

txCompleted

public void txCompleted()

End of Transaction

isInTransaction

public boolean isInTransaction()

This is used for remove on stateful session beans only.

Returns:

True if bean is participating in a client transaction

setMustCommit

public void setMustCommit(boolean mc)

set a flag to remember that the transaction must be committed

Specified by:

setMustCommit in class JSessionSwitch

saveBeanTx

public void saveBeanTx()

Keep the bean opened transaction for later use in other methods. Stateful session bean may open a transaction and use it in other methods. This is called at postInvoke

Specified by:

saveBeanTx in class JSessionSwitch

getLastAccessTime

public long getLastAccessTime()

Returns:

the last access time in milliseconds
