If I understand correctly your java code is in a j2ee application rather than a gbean? If your code is in or called by a gbean you should use the technique Guglielmo mentions. If your code is in a j2ee application you have to work harder, and you have to find or know the gbean name of the transaction manager.

static final ObjectName TM_NAME = new ObjectName("geronimo.server:J2EEApplication=null,J2EEModule=geronimo/ j2ee-server/1.0-SNAPSHOT/ car,J2EEServer=geronimo,j2eeType=TransactionManager,name=TransactionMana ger");


Kernel kernel = KernelRegistry.getSingleKernel();
TransactionManager tm = kernel.getProxyManager().createProxy(TM_NAME, TransactionManager.class);

I just wrote this code right here in this email so it is probably full of typos and bugs but it shows the technique to use. If you want to allow the transaction manager to be found even it it is in a different module you can use a object name pattern, list the names satisfying it and pick one.

thanks

Thanks Guglielmo,
But I want to get the reference to TransactionManager through java code only. Isn’t it possible to get it using the Transaction manager GBean name.

I had the same question. As per David Jencks:

==================================

 In your gbean info building code include something like this:

         infoFactory.addReference("TransactionManager",
 ExtendedTransactionManager.class, NameFactory.TRANSACTION_MANAGER);


 Then you won't have to specify the <type> in the reference.

 In the xml plan,

         <reference name="TransactionManager">
             <module>org/apache/geronimo/Server</module>
             <name>TransactionManager</name>
         </reference>

 assuming you are not using the patch I posted a few days ago that
 includes new-style configIds.
