public class WebLogicJtaTransactionManager
extends JtaTransactionManager

Special JtaTransactionManager variant for BEA WebLogic (7.0, 8.1 and higher). Supports the full power of Spring's transaction definitions on WebLogic's transaction coordinator, beyond standard JTA: transaction names, per-transaction isolation levels, and proper resuming of transactions in all cases.

Uses WebLogic's special begin(name) method to start a JTA transaction, in order to make Spring-driven transactions visible in WebLogic's transaction monitor. In case of Spring's declarative transactions, the exposed name will (by default) be the fully-qualified class name + "." + method name.

Supports a per-transaction isolation level through WebLogic's corresponding JTA transaction property "ISOLATION LEVEL". This will apply the specified isolation level (e.g. ISOLATION_SERIALIZABLE) to all JDBC Connections that participate in the given transaction.

Invokes WebLogic's special forceResume method if standard JTA resume failed, to also resume if the target transaction was marked rollback-only. If you're not relying on this feature of transaction suspension in the first place, Spring's standard JtaTransactionManager will behave properly too.

Automatically detects WebLogic Server 7.0 or 8.1+ and adapts accordingly. Usage on a WebLogic client is also supported, although with restricted functionality: transaction names cannot be applied there.

By default, the JTA UserTransaction and TransactionManager handles are fetched directly from WebLogic's TransactionHelper (on 8.1+) or TxHelper (on 7.0). This can be overridden by specifying "userTransaction"/"userTransactionName" and "transactionManager"/"transactionManagerName", passing in existing handles or specifying corresponding JNDI locations to look up.

WebLogicJtaTransactionManager

public WebLogicJtaTransactionManager()
Method Detail

afterPropertiesSet

public void afterPropertiesSet()
                        throws TransactionSystemException
Description copied from class: JtaTransactionManager
Initialize the UserTransaction as well as the TransactionManager handle.

Specified by:
afterPropertiesSet in interface InitializingBean
Overrides:
afterPropertiesSet in class JtaTransactionManager
Throws:
TransactionSystemException
See Also:
JtaTransactionManager.initUserTransactionAndTransactionManager()

retrieveUserTransaction

protected javax.transaction.UserTransaction retrieveUserTransaction()
                                                             throws TransactionSystemException
Description copied from class: JtaTransactionManager
Allows subclasses to retrieve the JTA UserTransaction in a vendor-specific manner. Only called if no "userTransaction" or "userTransactionName" specified.

The default implementation simply returns null.

Overrides:
retrieveUserTransaction in class JtaTransactionManager
Returns:
the JTA UserTransaction handle to use, or null if none found
Throws:
TransactionSystemException - in case of errors
See Also:
JtaTransactionManager.setUserTransaction(javax.transaction.UserTransaction), JtaTransactionManager.setUserTransactionName(java.lang.String)

retrieveTransactionManager

protected javax.transaction.TransactionManager retrieveTransactionManager()
                                                                   throws TransactionSystemException
Description copied from class: JtaTransactionManager
Allows subclasses to retrieve the JTA TransactionManager in a vendor-specific manner. Only called if no "transactionManager" or "transactionManagerName" specified.

The default implementation simply returns null.

Overrides:
retrieveTransactionManager in class JtaTransactionManager
Returns:
the JTA TransactionManager handle to use, or null if none found
Throws:
TransactionSystemException - in case of errors
See Also:
JtaTransactionManager.setTransactionManager(javax.transaction.TransactionManager), JtaTransactionManager.setTransactionManagerName(java.lang.String)

doJtaBegin

protected void doJtaBegin(JtaTransactionObject txObject,

                          javax.transaction.SystemException
Description copied from class: JtaTransactionManager

This implementation only supports standard JTA functionality: that is, no per-transaction isolation levels and no transaction names. Can be overridden in subclasses, for specific JTA implementations.

Calls applyIsolationLevel and applyTimeout before invoking the UserTransaction's begin method.

Overrides:
doJtaBegin in class JtaTransactionManager
Parameters:
txObject - the JtaTransactionObject containing the UserTransaction
definition - TransactionDefinition instance, describing propagation behavior, isolation level, read-only flag, timeout, and transaction name
Throws:
javax.transaction.NotSupportedException - if thrown by JTA methods
javax.transaction.SystemException - if thrown by JTA methods

Overrides:
doJtaResume in class JtaTransactionManager
Parameters:
txObject - the JtaTransactionObject containing the UserTransaction
suspendedTransaction - the suspended JTA Transaction object
Throws:
javax.transaction.InvalidTransactionException - if thrown by JTA methods
javax.transaction.SystemException - if thrown by JTA methods
