Re: Kandula interop sample - run transaction manger from service

[Thilina Gunarathne]

Hi,
Can u give some more details about ur scenerio, so that i can try to recreate the scenerion and check it. 
Also I'm bit confused about your usage too.
Are you trying to do all the registering and transactional service
calling things inside a mothod in another service implementation. So
that they'll execute when somebody calls the method.

Pls give me more clarifications. 

Thanks,
~Thilina

PS: I'm not the original author of Kandula1. My knowledge in the
Kandula j2ee stuff is very poor. May be there is an alternative by
using j2ee.

Hi Thilina,

 

have the same feeling but can't verify just now.  If this is the case how can I handle the problem?

Hi Michal,
When somebody starts and registers for a activity, Kandula associates the trasaction to the executing thread  (using a thread local variable).

 tm.getTransaction()

The above method basically looks for the transaction in the thread and  returns it to the caller (handler ).

I'm getting the feeling that this thread issue has to do something with your problem. just check whether the handler runs on a seperate thread.....

Hello,

 

Kandula interop sample works fine… however what about when I need to start the whole transaction stuff not from the client but from the service?

 

Let's assume service (call it Initiator) that contains functionality of InteropPortTypeRPCServiceTestCase.java from the sample (starts transaction manager, activate and register within coordinator service). This service invokes InteropService (like in the sample) and if transactions handlers within these services are deployed correctly, coordination context from Initiator should be passed to InteropService in the message header and initiates registration within the same activity. My trouble is that 

Transaction tx = tm.getTransaction() called from TransactionHandler while invoked refers to null. Where's the difference between interop sample and example described above?

 

Please correct me if the idea using transaction manager like in the sample is wrong or if there is more straightforward way how to get described functionality.

 

 

Many thanks

Michal Burian
