Weblogic Error: Caused by: weblogic.transaction.internal.AppSetRollbackOnlyException: setRollbackOnly called on transaction
提问by mwangi
I am porting an application from Jboss 7as to Weblogic 12c.
我正在将应用程序从 Jboss 7as 移植到 Weblogic 12c。
So far, I am able to run the application and create new records in the database.
到目前为止，我能够运行该应用程序并在数据库中创建新记录。
However, I get the below error only when trying to update existing records;
但是，只有在尝试更新现有记录时才会出现以下错误；
Error committing transaction:
javax.ejb.TransactionRolledbackLocalException: Error committing transaction:

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.
当我javax.persistence.EntityManager.merge(Object)在事务由容器管理的无状态 EJB 内部调用时，会发生错误。
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.
我最初的想法是容器在javax.transaction.UserTransaction.setRollbackOnly()某个地方调用，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。
I suspect that my Datasource or persistence.xml have a problem.
我怀疑我的数据源或persistence.xml 有问题。
Below is my persistence.xml's properties
下面是我的persistence.xml 的属性
<persistence version="2.0"

</properties>
Please assist.
请协助。

This is a default behaviour of Weblogic JTA realization. To obtain root exception you should set system property weblogic.transaction.allowOverrideSetRollbackReasonto true.
这是 Weblogic JTA 实现的默认行为。要获得根异常，您应该将系统属性设置weblogic.transaction.allowOverrideSetRollbackReason为true.
One of the solution is add this line into <domain_home>/bin/setDomainEnv.cmd:
解决方案之一是将此行添加到<domain_home>/bin/setDomainEnv.cmd：
set JAVA_OPTIONS=%JAVA_OPTIONS% -Dweblogic.transaction.allowOverrideSetRollbackReason=true
set JAVA_OPTIONS=%JAVA_OPTIONS% -Dweblogic.transaction.allowOverrideSetRollbackReason=true
or linux equivalent into <domain_home>/bin/setDomainEnv.sh
或 linux 等价于 <domain_home>/bin/setDomainEnv.sh
