Thank you Heinz.
I tried in other ways to manage a transaction, but I still have other problems about
Orion TXN.
What I wanted to do in my App. is as follows;
Let's assume that user class and address class exist and their relationship is 1-to-1.
1. Create a user
2. Create an address object of the user
if creating the address object is failed, I'd like to rollback "creating a user".
Trial 1>>
I used entity bean and session bean to manage the transaction as follows;
1. newUser method is one of the methods of a session bean, and the method's
transaction attribute is set to "RequiresNew"
2. newAddress method is one of the methods of User entity bean, and the mehtod's
transaction attribute is set to "Supports"
3. newUser method calls newAddress method.
But, even though creating the address failed, creating a user was not rollbacked, i.e.
new user was still in the database.
Tiral 2>>
I used ejbContext to get UserTransaction in newUser method of a session bean as
follows;
ejbContext.getUserTransaction().begin();
create a user
newAddress();
ejbContext.getUserTransaction().commit();
And set the session bean's TXN attribute to "Bean"
but, the result was the same as above.
Any advice appreciated.

Hi HK,
you can't get UserTransaction from an Application-Client-or
RMI-Client-Context. This (optional) feature is not supported by Orion.

Any advice appreciated.

Hi HK,
I think you should try
"java:comp/env/UserTransaction"

Subject: How can I get UserTransaction or TransactionManager
Hello, all.
Can you give me some advice how to get UserTransaction or
TrasactionManger?
I wrote some codes in my application as follows;
// Below codes are from Orion FAQ
import javax.naming.*;
import javax.transaction.*;
...
TransactionManager manager = (TransactionManager)new InitialContext
().lookup("java:comp/UserTransaction");
I didn't have any problem compiling my codes, but I met below error
while running my application
avax.naming.NameNotFoundException: java:comp/UserTransaction not found
at com.evermind.server.rmi.RMIContext.lookup(JAX)
Thank you in advance.
