I've got an issue getting connections from a data source from a log4j appender.
The appender is configured to use the same data source as the application, and when code from a @PreDestroy EJB method writes to log4j, this error occurs in the appender.

org.jboss.util.NestedSQLException:
Transaction is not active: tx=TransactionImple < ac, BasicAction: -53efa2b4:11e1:49f5f5da:70 status: ActionStatus.COMMITTED >;
- nested throwable: (javax.resource.ResourceException:
Transaction is not active: tx=TransactionImple < ac, BasicAction: -53efa2b4:11e1:49f5f5da:70 status: ActionStatus.COMMITTED >)

I'm expecting to get a connection back from the data source that I can use in autocommit mode (write the log to the database and return the connection to the pool)

Here is the data source definition, nothing fancy

 <local-tx-datasource>
 <jndi-name>scnDatasource</jndi-name>
 <connection-url>jdbc:oracle:thin:@cps-test-1:1521:CPSDEV</connection-url>
 <driver-class>oracle.jdbc.OracleDriver</driver-class>
 <user-name>test</user-name>
 <password>test</password>
 </local-tx-datasource>

Creating a copy of the data source, changing "local-tx-datasource" to "no-tx-datasource" makes the problem go away, but I'd rather use the same data source. I guess there's something I'm missing or not understanding. Are data sources supposed to be shareable like this?

I'm using jboss-5.0.0.GA + jboss-seam-2.1.1.GA

Cheers!
