Root cause and Solution for this issue:
You are missing jta.jar in your project lib directory or in the classpath, for maven add this dependency in your pom.xml file.

    <dependency>
          <groupId>javax.transaction</groupId>
          <artifactId>jta</artifactId>
          <version>1.1</version>
    </dependency>

or download JTA-<Version>.jar from maven repository and add to your CLASSPATH and lib directory.

The above solution is correct for Maven application. But in normal applications you just add a jar file called jta-<version>.jar.

If your using 3.x version, that is available under your downloading hibernate distribution jar's folder jta-<version>.jar.

If your using 4.x version, that is available under distribution folder path called dist/lib/provided/jta-<version>.jar

Multithreading in java with example

Multithreading  is one of the most important concept in core java. In this article we will learn what is multithreading? , what is the use of it? and What is the use of Synchronization and when to use it?  with detailed examples. At a time, two or more threads are accessing the same object is called as Multithreading  in Java .  First, we will create two threads for two objects. It is also possible to run two or more threads on a single class object. In this case, there is a possibility to get unreliable results. If the two threads are perform same task, then they need same object to be executed each time. For your better understanding, take an example of any reservations like, railway, movie ticket booking,etc. Let us think only one berth is available in a train and two passengers are asking for that berth. The first person has sent a request to allocate that ticket/berth to him. At the same time, the second person also sent a request to allocate that ticket/berth to him
