Single parameter report running from java application

Question

hi,
I had developed one servlet to run the crystal report template which will take one parameter.
The service method from my servlet I am placing here.
protected void service(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
          ReportClientDocument clientDocument = new ReportClientDocument();
          CrystalReportViewer viewer = new CrystalReportViewer();
          Fields fi= null;
          viewer.setName("one");
          try
               clientDocument.open("C:/Documents and Settings/Administrator/Desktop/lib-so/oneParamReport.rpt", 0);
          catch (ReportSDKException e)
               e.printStackTrace();
          Fields oFields = new Fields();  
                    ParameterField portfolio = new ParameterField();
                    portfolio.setName("Portfolio");
                   Values oValues = new Values();
                   ParameterFieldDiscreteValue oParameterFieldDiscreteValue = new ParameterFieldDiscreteValue();
                   oParameterFieldDiscreteValue.setValue(new Integer(16));
                   oValues.add(oParameterFieldDiscreteValue);
                   portfolio.setCurrentValues(oValues);
                   portfolio.setReportName(fileName);
                   oFields.add(portfolio);
          try {
               viewer.setParameterFields(oFields );
               viewer.processHttpRequest(request, response,request.getSession().getServletContext(), response.getWriter());
               viewer.dispose();
          } catch (ReportSDKExceptionBase e) {
               // TODO Auto-generated catch block
               e.printStackTrace();
while running this servlet I am getting one exception
"JRCAgent1 detected an exception: Error finding JNDI name (sql server)"
I am using jdk 6, sql server 2005, jboss 5, and crystal reports x1.
what could be the wrong in my code please tell me the reason and solution  for this .
thanks ,

Answer 1

thanks a lot neeraj for your response.I got resolved the database connection problem through programetically as shown bellow.
ITable table =  databaseController.getDatabase().getTables().getTable(0);
ITable oldtable = table;                     
table.setQualifiedName("sp2m.dbo." + table.getName());
IConnectionInfo connectionInfo = table.getConnectionInfo();
PropertyBag propertyBag = new PropertyBag();
propertyBag.put("Trusted_Connection", "false");
propertyBag.put("Server Name", "testsvr2"); //Optional property.
String CONNECTION_STRING="Use JDBC=b(true);Connection URL=s(jdbc:microsoft:sqlserver://testsvr2:1433); /Database Class Name=s(com.microsoft.jdbc.sqlserver.SQLServerDriver);Server=s(testsvr2); /User ID=s(sa);Password=cispl;Database=s(sp2m);Trusted_Connection=b(false); /JDBC Connection String=s(!com.microsoft.jdbc.sqlserver.SQLServerDriver!jdbc:microsoft:sqlserver://testsvr2:1433; /     DatabaseName=;user=;password=!)";
                    propertyBag.put("Connection String", CONNECTION_STRING);
                    propertyBag.put("Database Name", "sp2m");
                    propertyBag.put("Server Type", "JDBC (JNDI)");
                    String URI="!com.microsoft.jdbc.sqlserver.SQLServerDriver!jdbc:microsoft:sqlserver://testsvr2:1433;DatabaseName=;user=;password=!";
                    propertyBag.put("URI", URI);
                    propertyBag.put("Use JDBC", "true");
                    propertyBag.put("Database DLL", "crdb_jdbc.dll");
                    System.out.println("is this setlocation");            
                    connectionInfo.setAttributes(propertyBag);
                    connectionInfo.setUserName("sa");
                    connectionInfo.setPassword("cispl");
                    connectionInfo.setKind(ConnectionInfoKind.SQL);
                    table.setConnectionInfo(connectionInfo);
                    try {
                         databaseController.setTableLocationEx(oldtable,table);
                    } catch (ReportSDKException e) {
                         e.printStackTrace();
i am connecting mydatabase like above through programetically. it is coming fine , also it was working fine with crystal report tool, now I am getting new problem i.e crystal report engine not accepting parameter values set by me through program and asking to enter the parameters by generating one jsp page like as an interface in crystal report tool. Onece I submit that values it is generating the output properly .I have to avoid this unwanted page and I have to pass my parameter values from my jsp.
please help me in this,
thank u.
