Thanks Liao,

TransactionManager.

I think the gbean name should be:
"geronimo.server:J2EEApplication=null,J2EEModule=geronimo/j2ee-server/1.
0/car,J2EEServer=geronimo,
j2eeType=TransactionManager,name=TransactionManager" if you are using
the Geronimo-1.0 built at 2005-12-22.



Hope it helps,

Hi friends,

I tried to get a reference to TransactionManager using the code
suggested by David Jencks. But still its not working.



I am giving u a hint  what actually I am doing :



I have a java class that contain the above to return the
TransactionManager. I am calling this class through a JSP Page. I am
using the Geronimo-1.0 server. There is a snippet of the code in the
following line :



public TransactionManager getTransactionManager() {

 TransactionManager tm=null;

 try {

   ObjectName TM_NAME = new
ObjectName("geronimo.server:J2EEApplication=null,J2EEModule=geronimo/j2e
e-server/1.0-SNAPSHOT


/car,J2EEServer=geronimo,j2eeType=TransactionManager,name=TransactionMan
ager");

   Kernel kernel = KernelRegistry.getSingleKernel();

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

   }

   catch (Exception e) {

            System.out.println("Could not obtain Transaction Manager\n"+
e);

   }

   return tm;

}



But still its not working. Now the error is :



Could not obtain Transaction Manager

java.lang.IllegalArgumentException: Could not get GBeanInfo for target
object:
geronimo.server:J2EEApplication=null,J2EEModule=geronimo/j2ee-server/1.0
-SNAPSHOT/car,J2EEServer=geronimo,
j2eeType=TransactionManager,name=TransactionManager



I think the above GBean name is incorrect. Can anybody suggest me to how
to get the correct GBean name or any other way to get a reference to
transaction manager.



Thanks and Regard,

Rakesh Ranjan

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
