Add JTA test #9

Open emmanuelbernard opened 14 years ago

emmanuel>About JTA, it's more an Infinispan's business. I am just using the cache. If somebody tells me how to configure JTA in Infinispan + a standalone JTA TM, I can add a unit test for this.

manik>Just make sure your Infinispan configuration uses a TransactionManagerLookup. For JBoss TS standalone, make sure you use JBossStandaloneJTAManagerLookup. E.g.,

http://docs.jboss.org/infinispan/4.1/apidocs/org/infinispan/config/Configuration.html#setTransactionManagerLookup(org.infinispan.transaction.lookup.TransactionManagerLookup)

or if you are using an XML file to configure,

http://docs.jboss.org/infinispan/4.1/apidocs/config.html#ce_default_transaction

emmanuel>Note that I have JBoss TS standalone working in HSearch but the resource registration relies on SQL Datasource, not just any XAResource.

manik>Hmm. Maybe adding a UT would be a good idea, to flush out any nuances here.

Yes, I have this in place. Start any Infinispan test with -Dinfinispan.test.jta.tm=jbosstm and the test uses JBoss TS Standalone. Otherwise it uses an internal DummyTransactionManager stub.

Have a look at TransactionSetup, a test helper class that handles this.

This is used by the TestCacheManagerFactory which creates configurations and cache managers for the unit tests, injecting the appropriate transaction manager based on the system property.
