Question

我得到的异常是javax.transaction.NotSupportedException

当我将UserTransaction加入entityManager时，我正在使用与jpa的jta事务我将得到此异常

SampleCode：

        @Begin(join=true)
        public String tempCustomerMigration(List<DoTempCustomers>  list) {
            try {
             UserTransaction userTx = (UserTransaction) org.jboss.seam.Component.getInstance("org.jboss.seam.transaction.transaction");
             userTx.setTransactionTimeout(10 * 60);
             userTx.begin();
             for(DoTempCustomers tempCustomers:list){

                TempCustomers temp=new TempCustomers();
                BeanUtils.copyProperties(temp, tempCustomers);
                entityManager.joinTransaction();
                getEntityManager().persist(temp);
                getEntityManager().flush();
                userTx.commit();

                } catch (Exception e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                } 
            return "save";

                }

这种异常表示无法执行请求，因为该操作不是受支持的功能。例如，由于不支持嵌套事务，因此当已与事务关联的调用线程尝试启动新事务时，事务管理器将抛出此异常。当线程已与一个事务关联并尝试启动第二个事务时，就会发生嵌套事务。

在EntityManager中执行JoinTransaction时发生异常
