AbstractService
public AbstractService()
commit
public void commit(javax.transaction.xa.Xid xid,
boolean onePhase)
throws javax.transaction.xa.XAException
- Commit the global transaction specified by xid.
- Specified by:
commit in interface javax.transaction.xa.XAResource
end
public void end(javax.transaction.xa.Xid xid,
int flags)
throws javax.transaction.xa.XAException
- Ends the work performed on behalf of a transaction branch. The
resource manager disassociates the XA resource from the transaction
branch specified and let the transaction be completed.
If TMSUSPEND is specified in flags, the transaction branch is
temporarily suspended in incomplete state. The transaction context is
in suspened state and must be resumed via start with TMRESUME specified.
If TMFAIL is specified, the portion of work has failed. The resource
manager may mark the transaction as rollback-only.
If TMSUCCESS is specified, the portion of work has completed
successfully.
- Specified by:
end in interface javax.transaction.xa.XAResource
forget
public void forget(javax.transaction.xa.Xid xid)
throws javax.transaction.xa.XAException
- Tell the resource manager to forget about a heuristically completed
transaction branch.
- Specified by:
forget in interface javax.transaction.xa.XAResource
getTransactionTimeout
public int getTransactionTimeout()
throws javax.transaction.xa.XAException
- Obtain the current transaction timeout value set for this XAResource
instance. If XAResource.setTransactionTimeout was not use prior to
invoking this method, the return value is the default timeout set for
the resource manager; otherwise, the value used in the previous
setTransactionTimeout call is returned.
- Specified by:
getTransactionTimeout in interface javax.transaction.xa.XAResource
isSameRM
public boolean isSameRM(javax.transaction.xa.XAResource xares)
throws javax.transaction.xa.XAException
- This method is called to determine if the resource manager instance
represented by the target object is the same as the resouce manager
instance represented by the parameter xares.
- Specified by:
isSameRM in interface javax.transaction.xa.XAResource
prepare
public int prepare(javax.transaction.xa.Xid xid)
throws javax.transaction.xa.XAException
- Ask the resource manager to prepare for a transaction commit of the
transaction specified in xid.
- Specified by:
prepare in interface javax.transaction.xa.XAResource
recover
public javax.transaction.xa.Xid[] recover(int flag)
throws javax.transaction.xa.XAException
- Obtain a list of prepared transaction branches from a resource manager.
The transaction manager calls this method during recovery to obtain the
list of transaction branches that are currently in prepared or
heuristically completed states.
- Specified by:
recover in interface javax.transaction.xa.XAResource
rollback
public void rollback(javax.transaction.xa.Xid xid)
throws javax.transaction.xa.XAException
- Inform the resource manager to roll back work done on behalf of a
transaction branch.
- Specified by:
rollback in interface javax.transaction.xa.XAResource
setTransactionTimeout
public boolean setTransactionTimeout(int seconds)
throws javax.transaction.xa.XAException
- Set the current transaction timeout value for this XAResource instance.
- Specified by:
setTransactionTimeout in interface javax.transaction.xa.XAResource
start
public void start(javax.transaction.xa.Xid xid,
int flags)
throws javax.transaction.xa.XAException
- Start work on behalf of a transaction branch specified in xid If
TMJOIN is specified, the start is for joining a transaction previously
seen by the resource manager. If TMRESUME is specified, the start is
to resume a suspended transaction specified in the parameter xid. If
neither TMJOIN nor TMRESUME is specified and the transaction specified
by xid has previously been seen by the resource manager, the resource
manager throws the XAException exception with XAER_DUPID error code.
- Specified by:
start in interface javax.transaction.xa.XAResource
