Hi,

I am getting below error message when i am creating JtaTransactionManager bean by injecting AtomikosTransactionManager, AtomikosUserTransaction.

Can you please anyone help?

I have added below jars into my Tomcat lib and application classpath.

transactions-jta-3.9.3.jar
transactions-jms-3.9.3.jar
transactions-jdbc-3.9.3.jar
transactions-api-3.9.3.jar
transactions-3.9.3.jar
atomikos-util-3.9.3.jar

Added below configuration into spring config.xml.

      <bean id="AtomikosTransactionManager" 
          class="com.atomikos.icatch.jta.UserTransactionManager" 
          init-method="init" destroy-method="close">
                <!--  when close is called, should we force transactions to terminate or not?  -->
              <property name="forceShutdown" value="false" />
      </bean>
      <bean id="AtomikosUserTransaction" 
                class="com.atomikos.icatch.jta.UserTransactionImp">
              <property name="transactionTimeout" value="300" />
      </bean>
     
      <!-- Overwriting PlatformTransactionManager: soluminaTransactionManager (JDBC Transaction Manager) uses this -->
      <bean id="transactionManagerTest" 
        class="org.springframework.transaction.jta.JtaTransactionManager" depends-on="AtomikosTransactionManager,AtomikosUserTransaction">
              <property name="transactionManager" ref="AtomikosTransactionManager" />
              <property name="userTransaction" ref="AtomikosUserTransaction" />
              <property name="allowCustomIsolationLevels" value="true" />
      </bean>

Above issue is Class loader issue. I could able to fix the issue by removing the jta.jar file from WEB-INF/lib from my Webapp war file and add that jta.jar file into tomcat lib directory.
