To see TreeCache transaction at work, you start with the same setup with last section except you load the bsh of aopWithTx.bsh instead of aop.bsh. The additional snippets are:

import org.jboss.cache.PropertyConfigurator;
         import org.jboss.cache.aop.PojoCache;
         import org.jboss.cache.aop.test.Person;
         import org.jboss.cache.aop.test.Address;// Tx imports
         import javax.transaction.UserTransaction; import javax.naming.*;
         import org.jboss.cache.transaction.DummyTransactionManager;
         show(); // verbose mode for bean shell
         // Set up transaction manager
         DummyTransactionManager.getInstance();
         Properties prop = new Properties();
         prop.put(Context.INITIAL_CONTEXT_FACTORY,
	     "org.jboss.cache.transaction.DummyContextFactory");
         UserTransaction tx = (UserTransaction)new
	     InitialContext(prop).lookup("UserTransaction");
         PojoCache tree = new PojoCache();
         PropertyConfigurator config = new PropertyConfigurator(); 
	 // configure tree cache.
         config.configure(tree, "META-INF/replSync-service.xml");
         joe = new Person();
         joe.setName("Joe Black");
         joe.setAge(31);

         Address addr = new Address();
         addr.setCity("Sunnyvale");
         addr.setStreet("123 Albert Ave");
         addr.setZip(94086);
         joe.setAddress(addr);

         tree.startService(); // kick start tree cache
         tree.putObject("/aop/joe", joe); // add aop sanctioned object
         // since it is aop-sanctioned, use of plain get/set methods will take care
	 of cache contents automatically.
         // Also it is transacted
         tx.begin();
         joe.setAge(41);
         joe.getAddress().setZip(95124);
         tx.commit();
      

In this example, a default dummy transaction manager is used.

tx.begin();
         addr.setZip(95131);
         tx.rollback();
