Caused by: java.lang.NoClassDefFoundError: Ljavax/transaction/TransactionManager;

I read many posts about the error javax/transaction/TransactionManager, but none of those solutions fix my problem.

First thing to say is that I get that error when I deploy my web-application (made with Spring MVC and Hibernate) on the server. On my computer, with Eclipse and Tomcat 7 everything works.

Second thing to say is that on that server I have another web-application that's running under tomcat /root folder (this is a simple java application, that DOESN'T use neither Spring mvc nor Hibernate). The new application that i'm trying to deploy is running under another folder called /prova.

These are all the libraries of my application

Plus, according to what I read on some posts, I added to my lib folder:

1) jta-3.1.2.2.jar

2) hibernate3.3.1-jta-1.1.jar

3) javax.transaction.jar

In my xml file I have this bean that defines the transaction manager

<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
     <property name="sessionFactory" ref="sessionFactory" />
</bean>

Something strange is that in the server log the exact error is

Caused by: java.lang.NoClassDefFoundError: Ljavax/transaction/TransactionManager;

There's a L before javax/transaction/TransactionManager

Any idea?

Thank you

Don't worry with the "L", it just defines that the following is an object. You can find other letters :

BaseType
B     byte (signed byte)
C     char (Unicode character)
D     double (double-precision floating-point value)
F     float (single-precision floating-point value)
I     int (integer)
J     long (long integer)
L<classname>;     reference (an instance of class <classname>)
S     short (signed short)
Z     boolean (true or false)
[     reference (one array dimension )

To come back to your problem, did you define your transaction manager whith something close to this :

<bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager" p:sessionFactory-ref="sessionFactory">
</bean>

HibernateTransactionManager is an implementation of javax.transaction.TransactionManager

java.lang.NoClassDefFoundError: javax/transaction , java.lang.NoClassDefFoundError: javax/transaction/TransactionManager. Recently while trying to migrate one of the application from JDK6 to� Solution. The javax.transaction.TransactionManager is a class inside the J2EE SDK library “javaee.jar“, you are missing this jar file in your project classpath.. 1. J2EE SDK

you must add this dependency It is work

    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-core</artifactId>
     <version>5.4.2.Final</version>
    </dependency>

java.lang.ClassNotFoundException: javax.transaction , Hi Ibrahim. Thanks for quick response. jta is the dependency in hibernate (I have hibernate3.6 and hibernate-annotation 3.4.) so when I add jta.jar it cause class loader problem i.e. typeMismatchException for transaction manager.

where is spring-data jars? It looks like spring-data-commons. Please, spend some time to learn how to use maven or gradle. It will save a lot of your time.

The javax.transaction.TransactionManager is a class inside the J2EE SDK library “ javaee.jar “, you are missing this jar file in your project classpath.

I am trying to port Spring Boot to Java9 and I am hitting an issue that looks like Maven specific. I've managed to trim down the problem to a simple class that doesn't involve Spring Boot

This is caused by missing of the “jta.jar“, usually happened in Hibernate transaction development. java.lang.NoClassDefFoundError: javax/transaction

Hi man, I edited mypost, adding the bean of my transaction manager.
On your server, did you check that the libs in the classpath are the same than on your computer ? HibernateTransactionManager is provided by spring-orm, so it should be in the war. Maybe you should try adding spring-orm in tomcat external classpath to check that the one in the war is not skipped mysteriously ???
It came out the problem was the wrong name of the database. Now I don't get that error anymore. Thank you.
