Weblogic错误：导致：weblogic.transaction.internal.AppSetRollbackOnlyException：setRollbackOnly调用事务 [英] Weblogic Error: Caused by: weblogic.transaction.internal.AppSetRollbackOnlyException: setRollbackOnly called on transaction

问题描述

到目前为止，我能够运行应用程序并在数据库中创建新记录。

p>

但是，只有在尝试更新现有记录时，才会收到以下错误信息;

 提交事务时出错：
 javax.ejb.TransactionRolledbackLocalException：提交事务时出错：
 at weblogic.ejb.container.internal.EJBRuntimeUtils.throwTransactionRolledbackLocal（EJBRuntimeUtils.java:231）
 at weblogic。 ejb.container.internal.EJBRuntimeUtils.throwEJBException（EJBRuntimeUtils.java:134）
 at weblogic.ejb.container.internal.BaseLocalObject.postInvoke1（BaseLocalObject.java:362）

 at weblogic.ejb.container.internal.SessionLocalMethodInvoker.invoke（SessionLocalMethodInvoker.java:46）
 ... 
引起：weblogic .transaction.internal.AppSetRo llbackOnlyException：setRollbackOnly调用事务
  

当我调用 javax.persistence时发生错误.EntityManager.merge（Object）在一个无状态的EJB里面，它的事务是通过容器管理的。

我最初的想法是容器调用 javax.transaction.UserTransaction.setRollbackOnly（）在某处，所以我将EJB的事务管理更改为BMT并自己管理事务。发生了同样的错误。

我怀疑我的Datasource或persistence.xml有问题。

下面是我的persistence.xml的属性

 <持久性版本=2.0
 xmlns =http://java.sun.com/xml / ns / persistencexmlns：xsi =http://www.w3.org/2001/XMLSchema-instance
 xsi：schemaLocation =

< / properties> 
  

请协助。

解决方案

这是Weblogic JTA实现的默认行为。要获取根异常，您应该将系统属性 weblogic.transaction.allowOverrideSetRollbackReason 设置为 true 。

其中一个解决方案是将此行添加到< domain_home> /bin/setDomainEnv.cmd ：

$ p








$ b $相当于< domain_home> /bin/setDomainEnv.sh

I am porting an application from Jboss 7as to Weblogic 12c.

So far, I am able to run the application and create new records in the database.

However, I get the below error only when trying to update existing records;

Error committing transaction:
javax.ejb.TransactionRolledbackLocalException: Error committing transaction: 
at weblogic.ejb.container.internal.EJBRuntimeUtils.throwTransactionRolledbackLocal(EJBRuntimeUtils.java:231)
    at weblogic.ejb.container.internal.EJBRuntimeUtils.throwEJBException(EJBRuntimeUtils.java:134)
    at weblogic.ejb.container.internal.BaseLocalObject.postInvoke1(BaseLocalObject.java:362)
    at weblogic.ejb.container.internal.BaseLocalObject.__WL_postInvokeTxRetry(BaseLocalObject.java:205)
    at weblogic.ejb.container.internal.SessionLocalMethodInvoker.invoke(SessionLocalMethodInvoker.java:46)
    ...
Caused by: weblogic.transaction.internal.AppSetRollbackOnlyException: setRollbackOnly called on transaction

The error happens when I call javax.persistence.EntityManager.merge(Object) inside a Stateless EJB whose transactions are container managed.

My initial thoughts were that the container is calling javax.transaction.UserTransaction.setRollbackOnly() somewhere, so I changed the EJB's transaction management to BMT and managed the transaction myself. The same error occurred.

I suspect that my Datasource or persistence.xml have a problem.

Below is my persistence.xml's properties

<persistence version="2.0"
         xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="
    http://java.sun.com/xml/ns/persistence
    http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd">
    <persistence-unit name="myunitname" transaction-type="JTA">
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <jta-data-source>myDS</jta-data-source> 
 <properties>
 <property name="hibernate.hbm2ddl.auto" value="update" />
 <property name="hibernate.show_sql" value="false" />
 <property name="hibernate.format_sql" value="false" />
 <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle10gDialect" />
 <property name="hibernate.max_fetch_depth" value="1"/>
 <property name="hibernate.transaction.jta.platform" value="org.hibernate.service.jta.platform.internal.WeblogicJtaPlatform"/>
 </properties>

Please assist.

解决方案

This is a default behaviour of Weblogic JTA realization. To obtain root exception you should set system property weblogic.transaction.allowOverrideSetRollbackReason to true.

One of the solution is add this line into <domain_home>/bin/setDomainEnv.cmd:

set JAVA_OPTIONS=%JAVA_OPTIONS% -Dweblogic.transaction.allowOverrideSetRollbackReason=true

or linux equivalent into <domain_home>/bin/setDomainEnv.sh
