JCA: Sample Adapter Transaction Support

[Former Member]

Hi guys,

Could anyone tell me the transaction level supported by Sample Adapter.In the code they are using SAPResourceAdapter to access the J2EE Thread Manager.But in the code it has given that it won't support Local Transaction or XA Resource.

So what is the Transaction level supported by Sample Adapter.

regards,

in sample adapter, there is a transaction management.but i don't know clearly what it is.

txMgr = msRes.getTransactionManager();

txMgr.begin()

...

txMgr.commit().

can I remove this?

You have to distinguish between 1) the Transaction level support of the J2EE Connector Architecture (JCA) and 2) the internal usage of the J2EE transaction manager.

Ad 1) the XI docu says <i>JCA resource adapters can provide all kinds of JCA transactions. The Adapter Framework does not use them</i>. That's why the sample adapter uses NoTransaction.

Ad 2): The transaction manager has to be used for asynchronous processing (QoS Exactly Once). This is used for transaction management inside the adapter. For details see the sample adapter code or the Adapter Development docu http://help.sap.com/saphelp_nw04/helpdata/en/59/59d6409ff68631e10000000a1550b0/content.htm

Hi Siva,

As far as i know the transaction level supported by Sample Adapter is "NO TRANSACTION".

Hi Gowtham,

Transaction level: "No TRansaction" means it won't support transaction management or any other meaning.Then what about SAPResourceAdapter used in Sample Adapter.
