Question

我写了一个java代理来获取ssrs 2008的深入报告。如果我通过报告服务器URL访问它，它的工作完全正常，但在我的java spring应用程序中，它失去了功能。例如，我有一个向下钻取报告，如果我单击加号以展开它它在ssrs url中工作，但在我的jsp中，渲染的html没有，它必须像我使用报告服务器URL一样工作。这是我的代码示例，请告诉我这是否可行。

public String getReport(String ReportUrl) throws Exception
 {
  ReportExecutionServiceSoapStub service = getService();


   ExecutionInfo info = service.loadReport(ReportUrl, null); //Load report
   info.setHasDocumentMap(false);
   setExecutionId(service, info.getExecutionID()); //You must set the session id before continuing


   String format = "HTML4.0"; //Valid options are HTML4.0, MHTML, EXCEL, CSV, PDF, etc
   String deviceInfo = "<DeviceInfo><Toolbar>True</Toolbar></DeviceInfo>"; //Only generate an HTML fragment
   ByteArrayHolder result = new ByteArrayHolder();
   StringHolder extension = new StringHolder();
   StringHolder mimeType = new StringHolder();
   StringHolder encoding = new StringHolder();
   ArrayOfWarningHolder warnings = new ArrayOfWarningHolder();
   ArrayOfStringHolder streamIDs = new ArrayOfStringHolder();   

   service.render(format, deviceInfo, result, extension, mimeType, encoding, warnings, streamIDs); //Render report to HTML

   System.out.println(new String(result.value)); //Prints the report HTML; this could be embedded in a JSP   
   return new String(result.value);
 }

 public static void setExecutionId(ReportExecutionServiceSoapStub service, String id) throws SOAPException
 {
  SOAPHeaderElement sessionHeader = new SOAPHeaderElement("http://schemas.microsoft.com/sqlserver/2005/06/30/reporting/reportingservices", "ExecutionHeader");
  sessionHeader.addChildElement("ExecutionID").addTextNode(id);
  service.setHeader(sessionHeader);
 }

 public static ReportExecutionServiceSoapStub getService() throws Exception{

   String endpoint = "http://192.168.69.213/reportserver/ReportExecution2005.asmx";
   AuthPolicy.registerAuthScheme(AuthPolicy.NTLM, JCIFS_NTLMScheme.class);
   ReportExecutionServiceSoapStub service = (ReportExecutionServiceSoapStub)new ReportExecutionServiceLocator(getEngineConfiguration()).getReportExecutionServiceSoap(new URL(endpoint));
   service.setUsername("192.168.69.213\\administrator");
   service.setPassword("secret");

   return service;
 }

 public static org.apache.axis.EngineConfiguration getEngineConfiguration()
 {
  java.lang.StringBuffer sb = new java.lang.StringBuffer();

  sb.append("<?xml version=\"1.0\" encoding=\"UTF-8\"?>\r\n");
  sb.append("<deployment name=\"defaultClientConfig\"\r\n");
  sb.append("xmlns=\"http://xml.apache.org/axis/wsdd/\"\r\n");
  sb.append("xmlns:java=\"http://xml.apache.org/axis/wsdd/providers/java\">\r\n");
  sb.append("<globalConfiguration>\r\n");
  sb.append("<parameter name=\"disablePrettyXML\" value=\"true\"/>\r\n");
  sb.append("<parameter name=\"enableNamespacePrefixOptimization\" value=\"true\"/>\r\n");
  sb.append("</globalConfiguration>\r\n");
  sb.append("<transport name=\"http\" pivot=\"java:org.apache.axis.transport.http.CommonsHTTPSender\"/>\r\n");
  sb.append("<transport name=\"local\" pivot=\"java:org.apache.axis.transport.local.LocalSender\"/>\r\n");
  sb.append("<transport name=\"java\" pivot=\"java:org.apache.axis.transport.java.JavaSender\"/>\r\n");
  sb.append("</deployment>\r\n");

  return new org.apache.axis.configuration.XMLStringProvider(sb.toString());
 }

谢谢，任何帮助将不胜感激。

作为一种可能的解决方案，我将做以下几点。

Ssrs有正负gif图像，你可以下载并包含在你的战争项目中。用户将单击其中一个分组行，然后我将调用另一个报告以获取分组数据并将正图像替换为负图像。它几乎是钻研工作的方式，除了你做一些逻辑以不同方式构建html 如果您在浏览器中打开报告，请查看其来源以了解要操作的内容。

SSRS和JAVA向下钻取
