	Understanding JTA—the Java Transaction API (Site not responding. Last check: 2007-10-13)
		JTA specifies standard Java interfaces between the transaction manager and the other components in a distributed transaction: the application, the application server, and the resource managers.
		The transaction manager controls the boundaries of the transaction and is responsible for the final decision as to whether or not the total transaction should commit or rollback.
		JTA allows the XA resource to do a two-phase commit on the first branch even though the resource is still associated with the second branch.

		JTA is the abbreviation for the Java Transaction API.
		JTA transactions are global, that is, they are associated with a particular thread, not with a database connection.
		In a stateful session bean with a JTA transaction, the association between the bean instance and the transaction is retained across multiple client calls.

	Java theory and practice: Understanding JTS -- An introduction to transactions (Site not responding. Last check: 2007-10-13)
		Transactions allow us to modify the persistent state of an application in a controlled manner, so that our applications can be made robust to all sorts of system failures, including system crashes, network failures, power failures, and even natural disasters.
		The transaction log is stored as a sequential disk file (or sometimes in a raw partition) and will generally only be written to, not read from, except in the case of rollback or recovery.
		Transactions perform the role in enterprise applications that contract law plays in society -- they specify how commitments are unwound if one party fails to live up to their part of the contract.

	Transaction management under J2EE 1.2 - Java World
		A transaction can thus end in two ways: a commit, the successful execution of each step in the transaction, or a rollback, which guarantees that none of the steps are executed due to an error in one of those steps.
		Declarative transaction management refers to a non-programmatic demarcation of transaction boundaries, achieved by specifying within the deployment descriptor the transaction attributes for the various methods of the container-managed EJB component.
		If the calling component is already associated with a transaction context, that transaction is suspended, a new transaction context is created, and the method is executed in the context of the new transaction, after whose completion the calling component's transaction is resumed.

	Understanding JTA—the Java Transaction API: JDBC Topics: JDBC: Developer: Home (Site not responding. Last check: 2007-10-13)
		The Java® Transaction API (JTA) allows applications to perform distributed transactions, that is, transactions that access and update data on two or more networked computer resources.
		The JTA specifies standard Java interfaces between a transaction manager and the parties involved in a distributed transaction system: the application, the application server, and the resource manager that controls access to the shared resources affected by the transactions.
		Developers of transaction manager code must be conversant with all three interfaces of JTA: UserTransaction, TransactionManager, and XAResource, which are described in the Sun Java Transaction API (JTA) specification.

		However, the transaction involved only the single database and all updates made to the database were committed at the end of these changes.
		One of the primary advantages for a global transaction is the number database resources managed as a single unit within the transaction.
		When the global transaction ends, the two-phase commit engine ensures that all changes made to the databases A and B are committed or rolled back simultaneously.

	Java Transaction API - Wikipedia, the free encyclopedia
		The Java Transaction API (JTA) is one of the Java EE APIs allowing distributed transactions to be done across multiple XA resources.
		JTA is a specification developed under the Java Community Process as JSR 907.
		In the X/Open XA architecture, a transaction manager or transaction processing monitor (TP monitor), coordinates the transactions across multiple resources such as a database.

	Java Transaction Service
		Transaction context is an association between the transactional operations on the resources, and the objects invoking these operations.
		During the course of a transaction, the transaction context is shared by all objects participating in the transaction.
		Although the JTS is a Java implementation of the OMG OTS 1.1 specification, the JTA retains the simplicity of the XA and TX functional interfaces of the X/Open DTP model.

		object is used to explicitly enlist the database in the JTA transaction.
		The user that completes the transaction (as described in the binding section) must have the privilege to commit the transaction on all included databases.
		That is, when the transaction ends, the transaction manager contacts a coordinator--also known as a two-phase commit engine--to either commit or roll back all changes to all included databases.

		The JOTM (Java Open Transaction Manager) project from the guys at ObjectWeb is an open transaction manager that implements the XA protocol and is complies with the JTA APIs.
		In Bourgogne Transactions, a wide range of advanced transaction models can be employed thanks to newly introduced advanced transaction primitives that cover establishing flow control dependencies among transactions, sharing beans among transactions, and delegation of beans from one transaction to another.

	Java Transaction API
		If you are using JDBC calls to update a database, and you have an active transaction context, you should not also use JDBC to perform transaction services, by calling methods on the JDBC connection.
		When you commit using the JDBC connection, you are instructing a local transaction to commit, not the global transaction.
		When the connection is involved in a global transaction, trying to commit a local transaction within the global transaction causes an error to occur.

		You can enable application servers built on J2EE technology to manage transactions by using the Java Transaction API (JTA) supported by the Java Transaction Service (JTS).
		Using declarative statements in the deployment descriptor, you define the transactional properties of components that are based on Enterprise JavaBeans (EJB) technology during design or deployment and then let the application server take over the responsibility of transaction management.

	Chapter 9. Transaction management
		Global transactions have a significant downside, in that code needs to use JTA, and JTA is a cumbersome API to use (partly due to its exception model).
		Spring's declarative transaction management is made possible with Spring AOP, although, as the transactional aspects code comes with Spring and may be used in a boilerplate fashion, AOP concepts do not generally have to be understood to make effective use of this code.
		Declaring transaction semantics directly in the Java source code puts the declarations much closer to the affected code, and there is generally not much danger of undue coupling, since code that is meant to be used transactionally is almost always deployed that way anyway.
