Subject [jira] Created: (JCR-861) Connector should support LocalTransaction as well as XATransaction

Connector should support LocalTransaction as well as XATransaction
------------------------------------------------------------------

                 Key: JCR-861
                 URL: https://issues.apache.org/jira/browse/JCR-861
             Project: Jackrabbit
          Issue Type: Bug
          Components: jca
    Affects Versions: 1.2.3
         Environment: Websphere 5.1 on Linux, but may also apply on other platforms
            Reporter: Adam Hatherly
            Priority: Minor


According to the Java connector specification, an application server may choose to use a LocalTransaction
rather than an XATransaction if it determines that an XATransaction is not needed. Jackrabbit's
connector code supports XA transactions but throws an exception if the server requests a LocalTransaction.
The JCA code should be able to support LocalTransaction which could be easily mapped internally
to calls to the XAResource interface.

I get this problem when I deploy on Websphere 5.1, specifying XATransaction in the ra.xml
file - in normal usage Websphere tries to obtain a LocalTransaction resulting in the exception:

[17/04/07 15:32:58:887 BST] 57053d6b LocalTransact E J2CA0077E: An exception was caught
while trying to obtain a javax.resource.cci.LocalTransaction from a ManagedConnection for
resource jcr/local. The exception is: java.lang.UnsupportedOperationException: Local transaction
is not supported

My only workaround at present is to specify NoTransaction, but that may not be a good solution
for many people.
