public class WebSphereUowTransactionManager
extends JtaTransactionManager
implements CallbackPreferringPlatformTransactionManager
```
WebSphere-specific PlatformTransactionManager implementation that delegates to a UOWManager instance, obtained from WebSphere's JNDI environment. This allows Spring to leverage the full power of the WebSphere transaction coordinator, including transaction suspension, in a manner that is perfectly compliant with officially supported WebSphere API.
The CallbackPreferringPlatformTransactionManager interface implemented by this class indicates that callers should preferably pass in a TransactionCallback through the execute(org.springframework.transaction.TransactionDefinition, org.springframework.transaction.support.TransactionCallback<T>) method, which will be handled through the callback-based WebSphere UOWManager API instead of through standard JTA API (UserTransaction / TransactionManager). This avoids the use of the non-public javax.transaction.TransactionManager API on WebSphere, staying within supported WebSphere API boundaries.
This transaction manager implementation derives from Spring's standard JtaTransactionManager, inheriting the capability to support programmatic transaction demarcation via getTransaction / commit / rollback calls through a JTA UserTransaction handle, for callers that do not use the TransactionCallback-based execute(org.springframework.transaction.TransactionDefinition, org.springframework.transaction.support.TransactionCallback<T>) method. However, transaction suspension is not supported in this getTransaction style (unless you explicitly specify a JtaTransactionManager.setTransactionManager(javax.transaction.TransactionManager) reference, despite the official WebSphere recommendations). Use the execute(org.springframework.transaction.TransactionDefinition, org.springframework.transaction.support.TransactionCallback<T>) style for any code that might require transaction suspension.
This transaction manager is compatible with WebSphere 6.1.0.9 and above. The default JNDI location for the UOWManager is "java:comp/websphere/UOWManager". If the location happens to differ according to your WebSphere documentation, simply specify the actual location through this transaction manager's "uowManagerName" bean property.
NOTE: This JtaTransactionManager is intended to refine specific transaction demarcation behavior on Spring's side. It will happily co-exist with independently configured WebSphere transaction strategies in your persistence provider, with no need to specifically connect those setups in any way.
