exceptions in a transaction Servlets must be aware of exceptions and their implementation in terms of transactions the EJBS involved in a transaction may throw the following exceptions: Application exceptions (Exception applied)--if the EJB marks the transaction as rollback, then the client can only roll back. If no rollback is marked, the client can commit
When I started my computer at work in the morning, I found a problem with the application startup. The prompt was: Java. Lang. noclassdeffounderror: javax/transaction/transactionmanager. So I googled it and it turned out to be missing JTA. jar. It's strange that it was good. Why is it missing today? Is there a problem with eclipse.
JTA. jar:

There are three types of Java transactions: JDBC Transactions, JTA (Java Transaction API) transactions, container transactions. Common container transactions such as spring transactions, container transactions are mainly provided by the Java Application Server, container transactions are mostly based on JTA completion, which is a jndi based, rather complex API implementation. So this article does not discus
. The rest is to use spring to manage JTA. You can use jotm or atomikos, but it seems that jotm needs the support of JNDI, but it cannot be removed from the web server,While atomikos does not need the support of JNDI so brother recommended to use atomikos it is also an open source product, http://www.atomikos.com/downloads/transactions-essentials/3.5.5/AtomikosTransactionsEssentials-3.5.5.zipYou don't need to write a transaction code to manage

In the Java EE application, transactions are an indispensable component model that guarantees the ACID (i.e. atomic, consistent, isolated, persistent) properties of user operations. For applications that operate only a single data source, transaction management can be implemented through a local resource interface, and for large applications that span data sources, such as multiple databases or databases and JMS, you must use the global transaction JTA
Introduction:Spring's AOP technology allows us to enjoy a sumptuous feast of declarative transactions without EJB.By working with ObjectWeb's JOTM Open source project, spring can also provide JTA transactions without the need for a Java EE application server.Sping three ways to support JTA:1. Direct integration JOTM provides JTA transaction management (no applica
The previous article introduced the JDBC transaction, JDBC can handle the transaction of a single data source, satisfies most transaction processing requirements, but the JDBC transaction does not solve the problem of multi-data source and distributed transaction, the Java platform provides us with solution--jta. This article will explore some of the details of JTA. A distributed transaction Typically,

Java transaction learning notes (9)-in-depth analysis of JTA principles and implementationThrough the study of java transactions in this series, I have a preliminary understanding of the concept of transactions. However, with the rapid development of the Internet, the data volume is growing explosively, common databases are increasingly becoming the performance bottleneck of application systems. distributed databases have emerged. Correspondingly, jav
Hibernate is a lightweight package of JDBC that does not itself have transaction management capabilities, and at the transaction management level, Hibernate entrusts it to the underlying JDBC or JTA for transaction management and scheduling.Hibernate's default transaction handling mechanism is based on jdbctransaction, or it can be configured with JTA as a transaction management implementation through confi
There are many terms in the J2EE application system, including JTA and JTs. The first contact can feel a specific relationship between the two, but it cannot be defined as the name suggests. I usually use C ++ for development and seldom read these things. I don't know either of them. It's just a technology. However, due to the recent study, we need to figure out the relationship between the two. So I found some information on the Internet and thought

Java transaction types have three types of Java transactions: JDBC transaction, JTA (Java
JTA can use a transaction on multiple databases, WebLogic and other application servers provide JTA data source support, can be used directly. But Tomcat itself does not support this feature. If you want to use JTA on Tomcat, you must use a different tool. JOTM is a standalone component that can provide JTA functionali
The latest version of open-source cache framework ehcache supports post-write caching and uses Java transaction API (JTA) for transaction management, it also provides a cache plug-in for hibernate 3.3, a batch loading API for cluster cache, and a cache Reconfiguration Mechanism for runtime. Ehcache 2.0 introduces the write-through and write-behind caches. The direct write cache mode is used to write data to the cache of underlying resources (such as d

If you need to use more than one database in your business, we hope that in the business method, when the transaction of the data table of one database fails and is rolled back (rollback), the operation transaction of the data table of the other database is also rolled back, but the application of general transaction management can not achieve such a transaction management effect, This requires
The JTA (Java Transaction API) is an EE solution for transactional services. In essence, it is part of the Java EE model that describes the transaction interface, which developers use directly or through the Java-EE container to ensure that the business logic can run reliably.
The JTA has 3 interfaces, which are usertransaction interfaces, TransactionManager interfaces, and transaction interfaces respective
