Question

我正在使用现有的数据库和EJB 2.x应用程序。

我的任务是将应用程序从WebSphere 8迁移到JBOSS EAP 6.4

经过数天的努力，直到我们开始尝试使用某些bean之前，一切似乎都正常了。有些豆以“ Mgr”结尾。例如，有一个SiteMgr Bean和一个Site Bean。现在，所有Mgr Bean都可以工作，但其余的都不能。

如果您还不能确定，我不是EJB 2 Guru。这是错误的代码：

/**
 * getSessionContext
 */
public SiteVO getSite(int siteId) {
    SiteLocal siteLocal;
    try {
        siteLocal = getSiteHome().findByPrimaryKey(new SiteKey(siteId));
    } catch (FinderException e) {
        throw new EJBException(e);
    }

    return siteLocal.getSiteVO();       
}

因此，当我尝试findByPrimaryKey时，出现javax.ejb.FinderException，其原因如下：

java.sql.SQLSyntaxErrorException: ORA-00942: table or view does not exist

深入了解一下，这是原因：

Error : 942, Position : 27, Sql = SELECT t0_Site.siteId FROM SITE t0_Site WHERE t0_Site.siteId=:1 , OriginalSql = SELECT t0_Site.siteId FROM SITE t0_Site WHERE t0_Site.siteId=?, Error Msg = ORA-00942: table or view does not exist

该数据库包含一个名为APP_SITES的表，并且WebSphere应用程序可能使用一些似乎特定于WebSphere的文件来指出这一点。

有appdb70.dbm和Map.mapxmi

这些文件很长。我将提供一些特定于以上示例的示例文本。

ejb-jar.xml

        <ejb-name>Site</ejb-name>

        </cmp-field>
        ...

请注意，您可以在多个文件中找到“ CMPAttribute_1087249279390”。 JBOSS似乎没有利用这些额外的文件。

我现在不知道该怎么办。我想通了其他所有内容，但似乎无法解决。任何使bean正常工作的修补程序将不胜感激！
