Where to find jta.jar

For obtaining a quota extension you have to address Google directly. There's this form that you'll have to fill in. Than wait for response -- which, according to the experience of users of this forum, doesn't arrive shortly.

Other option would be to just discard delete the current app from Google's developers console and create a new one that will have assigned a new daily quota amount of usually 10, units.

I never heard that self-invocation breaks transaction. All I know is that self-invocation will not start a new transaction and you already mentioned the reason why. Note In proxy mode which is the default , only external method calls coming in through the proxy are intercepted. This means that self-invocation, in effect, a method within the target object calling another method of the target object, will not lead to an actual transaction at runtime even if the invoked method is marked with Transactional.

If you remove Transaction annotation from saveAB , you would observe that method saveA and saveB would not run under transaction even though it is annotated with Transactional.

However, if you call saveA or saveB from outside the class, it will run under transaction as expected. That is the reason why people advice to be cautious with self-invocation.

That does not mean that there will only be one single transaction for all your clients - each client will start from a non-transactional context, and as soon as the the request processing will hit a Transactional , it will create a new transaction.

At the moment, it may be unnecessary. But I think we should update this ticket for someone. It works for me. These resources could consist of several different RDBMSs housed on a single sever, for example, Oracle, SQL Server, and Sybase; or they could include several instances of a single type of database residing on a number of different servers.

In any case, a distributed transaction involves coordination among the various resource managers. This coordination is the function of the transaction manager. The transaction manager is responsible for making the final decision either to commit or rollback any distributed transaction.

A commit decision should lead to a successful transaction; rollback leaves the data in the database unaltered. 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.

This relationship is illustrated in the following diagram:. The numbered boxes around the transaction manager correspond to the three interface portions of JTA:. UserTransaction interface provides the application the ability to control transaction boundaries programmatically. The javax. UserTransaction method starts a global transaction and associates the transaction with the calling thread.

TransactionManager interface allows the application server to control transaction boundaries on behalf of the application being managed.

Developers of code at the application level should not be concerned about the details of distributed transaction management. This is the job of the distributed transaction infrastructure-the application server, the transaction manager, and the JDBC driver. The only caveat for application code is that it should not invoke a method that would affect the boundaries of a transaction while the connection is in the scope of a distributed transaction.

Specifically, an application should not call the Connection methods commit, rollback, and setAutoCommit true because they would interfere with the infrastructure's management of the distributed transaction. The transaction manager is the primary component of the distributed transaction infrastructure; however, the JDBC driver and application server components should have the following characteristics:.

The first step of the distributed transaction process is for the application to send a request for the transaction to the transaction manager. A transaction branch is associated with a request to each resource manager involved in the distributed transaction.

Each transaction branch must be committed or rolled back by the local resource manager. 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.

This decision is made in two phases, called the Two-Phase Commit Protocol. In the first phase, the transaction manager polls all of the resource managers RDBMSs involved in the distributed transaction to see if each one is ready to commit. If a resource manager cannot commit, it responds negatively and rolls back its particular part of the transaction so that data is not altered. In the second phase, the transaction manager determines if any of the resource managers have responded negatively, and, if so, rolls back the whole transaction.

If there are no negative responses, the translation manager commits the whole transaction, and returns the results to the application. The component of the driver connected with the XAResource interface is responsible for "translating" between the transaction manager and the resource manager.

The following section provides examples of XAResource calls. To simplify the explanation of XAResource, these examples illustrate how an application would use JTA when there is no application server and transaction manager involved. Basically, the application in these examples is also acting as application server and transaction manager.
