使用 SDK 客户端的 Business Object Enterprise 报告出现异常

Question

我们有一个客户端正在使用 SDK 来调用 Business Objects 嵌入式报表服务器上的报表。我们可以登录，但是当调用 openDocument 方法时，出现问题。

代码：

     //LOGON
IEnterpriseSession session = sessionMgr.logon(username, password, clusterNode,     authType);
IInfoStore infoStore = (IInfoStore)session.getService("InfoStore");

//GET REPORT OBJECT
String queryForFolder = "Select SI_ID, SI_NAME From CI_INFOOBJECTS Where SI_NAME = '" + folderName + "'";
IInfoObjects queryForFolderResult = infoStore.query(queryForFolder);
 if (queryForFolderResult.isEmpty())
 {
   throw new Exception("No Folder Found");
 }
 //report folder found
 IInfoObject reportFolder = (IInfoObject)queryForFolderResult.get(0);

String queryForFile = "Select SI_ID, SI_NAME From CI_INFOOBJECTS Where SI_NAME = '" + reportFile + "'" + " and SI_PARENTID = " + reportFolder ;

IReportAppFactory reportAppFactory = (IReportAppFactory)session.getService("RASReportFactory");
IInfoObjects queryForFileResult = infoStore.query(queryForFile);

if (queryForFileResult.isEmpty())
{
  throw new Exception("Report file not found");
}
//report found
IReport report = (IReport)queryForFileResult.get(0);

//OPEN REPORT
clientDoc = reportAppFactory.openDocument(report, 0, locale); /*row 58 in exception*/

例外：

登录时通信显然有效。如果您有任何想法或知道我可以去哪里寻找答案，请告诉我。 ：）

问候， 卡尔

Answer 1

经过进一步的研究，这就是我发现的。第一个错误是由于使用早期版本的 BO SDK 引起的。第二个错误“CORBA 通信失败：原因[错误号 WSAETIMEDOUT]”是在 iiop 端口未打开时发生的。我通过设置 SDK 侦听器端口解决了这个问题（文档中所述 http://www.sdn.sap.com/irj/boc/go/portal/prtroot/docs/library/uuid/ 0047e5f4-3140-2b10-1bae-de175e4c741c?QuickLink=index&overridelayout=true）并三次检查防火墙打开是否正确。

我猜测您正在使用的 ReportEngine（变量 reportAppFactory）对于您尝试打​​开的文档类型不正确。

另一种可能性是，这是一个 DeskI 报告，它正在寻找能够打开该文档的连接服务器组件。

如果您能提供更多详细信息，我会尽力提供帮助。
