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

Question

我们有一个使用 SDK 调用 Business Objects Embedded Report Server 上的报告的客户端。可以登录了，但是调用openDocument方法的时候出问题了。

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

经过进一步研究，这是我发现的。第一个错误是由于使用了早期版本的 BO SDK。第二个错误“CORBA 通信失败：原因[错误号 WSAETIMEDOUT]”在 iiop 端口未打开时发生。我通过设置 SDK 侦听器端口（在文档 http://www.sdn.sap.com/irj/boc/go/portal/prtroot/docs/library/uuid/0047e5f4-3140-2b10-1bae-de175e4c741c?QuickLink=index&overridelayout=true 中描述）解决了这个问题，并三重检查是否打开了正确的防火墙。

我猜您正在使用的 ReportEngine，您的变量 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 报表，它正在寻找能够打开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。
