Java持久化操作每次都会导致MySQL数据库中的回滚

我有个问题

我有这个功能：

public boolean insertOrgToAlign(OrganizationData orgData) {
        try {
            if (eManager.find(ScOrgNotAligned.class, orgData.getOrganizationCode()) == null) {
                ScAdminGroup rootByOrg = null;
                AdminGroupBean admGrp = null;
                try {
                    rootByOrg = adminGroupServices.getRootAdminGroupByOrg(orgData.getOrganizationCode());
                } catch (NoResultException e) {
                    logger.debugT("insertOrgToAlign(..) - org to align has no root");
                    return false;
                } catch (NonUniqueResultException e) {
                    logger.debugT("insertOrgToAlign(..) - org to align has more than one root");
                    admGrp = new AdminGroupBean();
                    admGrp.setAdmGroupId(-1);
                    admGrp.setAdmGroupName("ERROR");
                    ScOrgNotAligned scOrgNotAlig = new ScOrgNotAligned(orgData, admGrp);
                    eManager.persist(scOrgNotAlig);
                    logger.debugT("insertOrgToAlign(..) - persist org to adjust manually : "
                            + orgData.getOrganizationName());
                    return true;
                }
                admGrp = new AdminGroupBean(rootByOrg);
                ScOrgNotAligned scOrgNotAlig = new ScOrgNotAligned(orgData, admGrp);
                //**************************
                //THIS IS THE WRONG LINE????
                eManager.persist(scOrgNotAlig);
                //**************************
                logger.debugT("insertOrgToAlign(..) - persist org to align : " + orgData.getOrganizationName());
            } else {
                logger.debugT("insertOrgToAlign(..) - org to align already exists in db : "
                        + orgData.getOrganizationName());
            }
        } catch (Exception e) {
            logger.traceThrowableT(Severity.ERROR, e.getMessage(), e);
            return false;
        }
        return true;
    }

如果我评论eManager.persist（scorgontalig）line，函数写在DB中；如果我取消对该行的注释，该函数将在写入DB时导致回滚

异常的堆栈跟踪是：

(Failed in component: sap.com/tc~ejbexplorer~ear, BC-JAS-EJB) nested exception is: 
com.sap.engine.services.ts.exceptions.BaseRollbackException: Exception in
beforeCompletion of ( JTA Transaction : 45491 ).

为什么?？有什么想法吗？

你能给我们看看例外情况的堆栈跟踪吗？我添加到Question；）嗯，这似乎不是（整个）堆栈跟踪。。。如果这就是你所得到的，我帮不了你多少…在stacktrace中，我没有例外！这是件奇怪的事。。。。我只在EJB资源管理器页面中获得此信息。。。
