Subject Re: XA Transaction with multiple xa-connections not working on rollback
Date Sat, 06 Apr 2013 19:41:42 GMT
glassfish code just does that:

it know the following resources states (one TransactionContext per
connection - same xid,same branch => imo ok because
TransactionContext.isSameRM returns true)

TransactionContext{transactionId=XID[4871251,globalId=4000ffffffcaffffff98ffffffceffffffe064676e622c7365727665722c50313030,branchId=64676e622c7365727665722c503130302c0]}=0,
TransactionContext{transactionId=XID:[4871251,globalId=4000ffffffcaffffff98ffffffceffffffe064676e622c7365727665722c50313030,branchId=64676e622c7365727665722c503130302c0]}=0

on rollback glassfish just calls end(xid,flags) once per xaresource (the xa
resources above are equal i guess)

on commit glassfish calls end(xid,flags) for every resource state
(transactioncontext)

don't know if this is correct - i didn't find anything in the jta-specs...

or maybe it is wrong to consider that two xa resources are equal for
different activemq-connections -> TransactionContext.isSameRM()
