10.4. About JTA Transaction Manager Lookup Classes

In order to execute a cache operation, the cache requires a reference to the environment's Transaction Manager. Configure the cache with the class name that belongs to an implementation of the TransactionManagerLookup interface. When initialized, the cache creates an instance of the specified class and invokes its getTransactionManager() method to locate and return a reference to the Transaction Manager.

Class Name Details
org.infinispan.transaction.lookup.DummyTransactionManagerLookup Used primarily for testing environments. This testing transaction manager is not for use in a production environment and is severely limited in terms of functionality, specifically for concurrent transactions and recovery.
org.infinispan.transaction.lookup.JBossStandaloneJTAManagerLookup It is a fully functional JBoss Transactions based transaction manager that overcomes the functionality limits of the DummyTransactionManager.
org.infinispan.transaction.lookup.GenericTransactionManagerLookup GenericTransactionManagerLookup is used by default when no transaction lookup class is specified. This lookup class is recommended when using JBoss Data Grid with Java EE-compatible environment that provides a TransactionManager interface, and is capable of locating the Transaction Manager in most Java EE application servers. If no transaction manager is located, it defaults to DummyTransactionManager.
It is important to note that when using Red Hat JBoss Data Grid with Tomcat or an ordinary Java Virtual Machine (JVM), the recommended Transaction Manager Lookup class is JBossStandaloneJTAManagerLookup, which uses JBoss Transactions.
