When executing spring transaction

Question

I'm new to springs. I want to implement JTATransactionManager in my application instead of HibernateTransactionManager. But I get the following error when I write the following code in my xml.

<bean id="transactionManager" class="org.springframework.transaction.jta.JtaTransactionManager"/> 

When starting the server, the following error occurs: -

 org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'transactionManager' defined in ServletContext resource [/WEB-INF/resources/transaction-context.xml]: Invocation of init method failed; nested exception is java.lang.IllegalStateException: No JTA UserTransaction available - specify either 'userTransaction' or 'userTransactionName' or 'transactionManager' or 'transactionManagerName' at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1282) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.createBean(AbstractAutowireCapableBeanFactory.java:510) at org.springframework.beans.factory.support.AbstractBeanFactory$1.getObject(AbstractBeanFactory.java:246) at org.springframework.beans.factory.support.DefaultSingletonBeanRegistry.getSingleton(DefaultSingletonBeanRegistry.java:166) at org.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:243) at org.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:167) at org.springframework.beans.factory.support.DefaultListableBeanFactory.preInstantiateSingletons(DefaultListableBeanFactory.java:351) at org.springframework.context.support.AbstractApplicationContext.finishBeanFactoryInitialization(AbstractApplicationContext.java:689) at org.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:358) at org.springframework.web.context.ContextLoader.createWebApplicationContext(ContextLoader.java:244) at org.springframework.web.context.ContextLoader.initWebApplicationContext(ContextLoader.java:187) at org.springframework.web.context.ContextLoaderListener.contextInitialized(ContextLoaderListener.java:49) at org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:3827) at org.apache.catalina.core.StandardContext.start(StandardContext.java:4334) at org.apache.catalina.core.ContainerBase.addChildInternal(ContainerBase.java:791) at org.apache.catalina.core.ContainerBase.addChild(ContainerBase.java:771) at org.apache.catalina.core.StandardHost.addChild(StandardHost.java:525) at org.apache.catalina.startup.HostConfig.deployDirectory(HostConfig.java:920) at org.apache.catalina.startup.HostConfig.deployDirectories(HostConfig.java:883) at org.apache.catalina.startup.HostConfig.deployApps(HostConfig.java:492) at org.apache.catalina.startup.HostConfig.start(HostConfig.java:1138) at org.apache.catalina.startup.HostConfig.lifecycleEvent(HostConfig.java:311) at org.apache.catalina.util.LifecycleSupport.fireLifecycleEvent(LifecycleSupport.java:117) at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1053) at org.apache.catalina.core.StandardHost.start(StandardHost.java:719) at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1045) at org.apache.catalina.core.StandardEngine.start(StandardEngine.java:443) at org.apache.catalina.core.StandardService.start(StandardService.java:516) at org.apache.catalina.core.StandardServer.start(StandardServer.java:710) at org.apache.catalina.startup.Catalina.start(Catalina.java:566) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.apache.catalina.startup.Bootstrap.start(Bootstrap.java:288) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:413) Caused by: java.lang.IllegalStateException: No JTA UserTransaction available - specify either 'userTransaction' or 'userTransactionName' or 'transactionManager' or 'transactionManagerName' at org.springframework.transaction.jta.JtaTransactionManager.checkUserTransactionAndTransactionManager(JtaTransactionManager.java:489) at org.springframework.transaction.jta.JtaTransactionManager.afterPropertiesSet(JtaTransactionManager.java:429) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.invokeInitMethods(AbstractAutowireCapableBeanFactory.java:1310) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1279) ... 35 more 30 Dec, 2009 6:43:10 PM org.apache.catalina.core.StandardContext listenerStart SEVERE: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'transactionManager' defined in ServletContext resource [/WEB-INF/resources/transaction-context.xml]: Invocation of init method failed;

Answer 1

Tomcat does not have a built-in JTA implementation, so Spring will fail if you try to use the JtaTransactionManager .

However, you can use JOTM , which Tomcat can use to provide this functionality.

I must ask, however, why do you want to start JTA? Is the sleep mode transaction manager insufficient? If you need JTA support, you may need to use the full JavaEE application server (JBoss will be the obvious choice, since it includes Tomcat as a servlet engine) and use the proper fully supported JTA implementation there.

Answer 2

As a scuffman, sadly, Tomcat does not have a built-in JTA implementation. Therefore, to use the JTATransactionManager in the context of your application, you must place the JAR versions of some JTA implementation (e.g. Bitronix) in the Tomcat lib folder and place the following declaration in the Tomcat context.xml

 <Transaction factory="bitronix.tm.BitronixUserTransactionObjectFactory" /> 

In this way, Tomcat will create and publish the UserTransaction, which is used when initializing the JtaTransactionManager.

Answer 3

I have an answer for a specific case if you use Atomikos to implement JTA, and I solved the problem by adding these lines below to the context.xml file in the / conf folder.

 <!-- Spring LoadTimeWeaver Support for the Tomcat server. --> <Loader loaderClass="org.springframework.instrument.classloading.tomcat.TomcatInstrumentableClassLoader"/>
