JPA（Hibernate）、JTA（JOTM）和Tomcat

Question

我正在开发一个以JPA（Hibernate）为后端的应用程序。我对每个实体都有一个DAO和JPADAO，我的流程将不止一个实体作为一个工作单元进行更新，所以我决定使用JTA，因为它允许我控制事务，所以我的代码看起来是持久的。xml

    <persistence-unit name="Pub" transaction-type="JTA">
      <provider>org.hibernate.ejb.HibernatePersistence</provider>
       <jta-data-source>java:comp/env/jdbc/dcapps</jta-data-source>

     <property name="hibernate.dialect" value="org.hibernate.dialect.InformixDialect"/>
        <property name="transactionSynchronizationRegistryName" value="java:comp/env/TransactionSynchronizationRegistry"/>
        <property name="hibernate.transaction.jta.platform" value="org.hibernate.service.jta.platform.internal.JOTMJtaPlatform"/>


            web.xml
      <resource-ref>
  <description>DB Connection</description>
  <res-ref-name>jdbc/dcapps</res-ref-name>
  <res-type>javax.sql.DataSource</res-type>
  <res-auth>Container</res-auth>

<resource-env-ref>
<description>JTA transaction manager</description>
<resource-env-ref-name>jta/UserTransaction</resource-env-ref-name>
<resource-env-ref-type>javax.transaction.UserTransaction</resource-env-ref-type>
</resource-env-ref>

    <resource-env-ref>
<description>JTA Transaction Synchronization Registry</description>
<resource-env-ref-name>TransactionSynchronizationRegistry</resource-env-ref-name>
<resource-env-ref-type>javax.transaction.TransactionSynchronizationRegistry
 </resource-env-ref-type>
 </resource-env-ref>


         content.xml(Tomcat 7)
        <Resource name="jdbc/dcapps" auth="Container" type="javax.sql.DataSource"
               maxActive="20" maxIdle="10" maxWait="-1"
               username="dcapps" password="dcapps" driverClassName="com.informix.jdbc.IfxDriver"
               url="jdbc:informix-sqli://fddb.fd.gtwy.dcn:7101/fd_test:INFORMIXSERVER=fd_ecf"/>

 <Resource
        name="TransactionSynchronizationRegistry"
        auth="Container"
        type="javax.transaction.TransactionSynchronizationRegistry"
        factory="org.objectweb.jotm.TransactionSynchronizationRegistryFactory"/>

<Transaction
        factory="org.objectweb.jotm.UserTransactionFactory"
        jotm.timeout="60"/>





        Process.java
       Context initContext = new InitialContext();
     utx  = (UserTransaction)initContext.lookup("java:comp/UserTransaction");
             dktPartDAO.getEntityManager().joinTransaction();
            dkttextDAO.getEntityManager().joinTransaction();
            reqHDAO.getEntityManager().joinTransaction();
            reqDDAO.getEntityManager().joinTransaction();
            costDAO.getEntityManager().joinTransaction();
            reportDDAO.getEntityManager().joinTransaction();
            caseflagDAO.getEntityManager().joinTransaction();
            redStatusDAO.getEntityManager().joinTransaction();
            pcdktPartDAO.getEntityManager().joinTransaction();
            pcDkttextDAO.getEntityManager().joinTransaction();
                           utx.commit();

现在，当我尝试开始一个事务并将更改提交给实体（不止一个）时，它会抛出和异常，并调用utx。回滚但不会回滚它只提交了部分事务，并没有保存所有实体

         Exception
      java.lang.IllegalStateException: Cannot get Transaction for rollback

Answer 1

您没有提到您使用的是哪个版本的JOTM，但我在使用v2时遇到了完全相同的问题。2.1. 降级到v2版本。1.9为我解决了这个问题。

显然最近已经修好了，看到了吗http://websvn.ow2.org/comp.php?repname=jotm
