Which of the following are true about the transaction support in the WebLogic server?
Answer:
a. WebLogic Server allows transactions to be terminated only by the client that created the transaction.
b. WebLogic Server does not support multithreaded transactional clients.
c. A client or a server object cannot invoke methods on an object that is participating in another transaction.
d. WebLogic server supports Nested Transactions
Choices A and C are correct. WebLogic Server provides a Transaction Service that supports transactions in EJB and RMI applications. WebLogic Server allows transactions to be terminated only by the client that created the transaction. WebLogic Server implements the flat transaction model. Nested transactions are not supported.
WebLogic Server supports multithreaded transactional clients. Clients can make transaction requests concurrently in multiple threads. In WebLogic Server, a client or a server object cannot invoke methods on an object that is infected with (or participating in) another transaction. The method invocation issued by the client or the server will return an exception. Also in WebLogic Server, clients using third-party implementations of the Java Transaction API (for Java applications) are not supported.
