使用Java呈现SSRS报告

Question

我正在研究一个应该用Java呈现SSRS报告的项目。

以下是我遵循的程序。

1. 已安装的Eclipse
2. 创建一个java项目通过设置Execution Environment Java SE 1.8
3. 使用wsimport创建代理

wsimport image

1. 添加了生成代理的引用

1. 编写此代码

   import javax.xml.ws.BindingProvider;
   import javax.xml.ws.Holder; 
   
   import  com.microsoft.schemas.sqlserver._2005._06._30.reporting.reportingservices.ArrayOfString;
   import com.microsoft.schemas.sqlserver._2005._06._30.reporting.reportingservices.ArrayOfWarning;
   import com.microsoft.schemas.sqlserver._2005._06._30.reporting.reportingservices.ExecutionHeader;
   import com.microsoft.schemas.sqlserver._2005._06._30.reporting.reportingservices.ExecutionInfo;
   import com.microsoft.schemas.sqlserver._2005._06._30.reporting.reportingservices.ReportExecutionService;
   import com.microsoft.schemas.sqlserver._2005._06._30.reporting.reportingservices.ReportExecutionServiceSoap;
   
   
     public class Render {
   
    static {
             java.net.Authenticator.setDefault(new java.net.Authenticator()   {
       @Override
       protected java.net.PasswordAuthentication getPasswordAuthentication() {
           return new java.net.PasswordAuthentication("username", "pwd".toCharArray());
       }
   });
   }
   
   public static void main(String[] args) {
   
   String reportPath = "/Reporting/Customers" ;
   String format = "HTML4.0";
   String historyID = null;
   String devInfo = "<DeviceInfo><Toolbar>False</Toolbar><HTMLFragment>True</HTMLFragment></DeviceInfo>";
   String executionID = null;
   Holder<String> extension = null;
   Holder<String> mimeType = null;
   Holder<String> encoding = null;
   Holder<ArrayOfWarning> warnings = null;
   Holder<ArrayOfString> streamIDs = null;
   Holder<byte[]> result = new Holder<byte[]>(); 
   
   ReportExecutionService res = new ReportExecutionService();
   ReportExecutionServiceSoap ress = res.getReportExecutionServiceSoap(); 
   
   BindingProvider bp = (BindingProvider)ress; 
   
   bp.getRequestContext().put(BindingProvider.SESSION_MAINTAIN_PROPERTY, true);  
   
   ExecutionInfo execInfo = new ExecutionInfo();  
   execInfo = ress.loadReport(reportPath, historyID); 
   executionID = execInfo.getExecutionID();       
   bp.getRequestContext().put("sessionID", executionID); 
   
   ExecutionHeader eh = new ExecutionHeader();
   eh.setExecutionID(executionID); 
   System.out.println(executionID);
   ress.render(format, devInfo, result, extension, mimeType, encoding, warnings, streamIDs);
   
   String resultString = new String(result.value); 
   
   }
   
   }
   

当我运行此代码时，我收到以下错误。

     Exception in thread "main"    com.sun.xml.internal.ws.fault.ServerSOAPFaultException: Client received SOAP Fault from server: The session identifier is missing. A session identifier is required for this operation.  ---> Microsoft.ReportingServices.Diagnostics.Utilities.MissingSessionIdException: The session identifier is missing.

我是java新手，我错过了什么？我已经设置了会话ID。

任何帮助表示赞赏。

提前致谢。
