22.4. The Transaction Manager
Use the following to obtain the TransactionManager from the cache:
TransactionManager tm = cache.getAdvancedCache().getTransactionManager();
To execute a sequence of operations within transaction, wrap these with calls to methods begin() and commit() or rollback() on the TransactionManager:
Example 22.1. Performing Operations
tm.begin();
Object value = cache.get("A");
cache.remove("A");
Object prev = cache.put("B", value);
if (prev == null)
tm.commit();
else
tm.rollback();Note
If a cache method returns a CacheException (or a subclass of the CacheException) within the scope of a JTA transaction, the transaction is automatically marked to be rolled back.
To obtain a reference to a Red Hat JBoss Data Grid XAResource, use the following API:
XAResource xar = cache.getAdvancedCache().getXAResource();
