JRC and XML Data Source

Question

Hi!
Does the JRC execute a report with an XML data source (URL XML Http and URL XSD Http) ?
If yes, does the JRC change programmatically the XML data source (URL XML Http and URL XSD Http) prior to execute the report?
There is an example to do this?
Best regards,
A.

Hi,
I've follow the example [ftp://ftp.businessobjects.com/pub/incoming/XML_XSD_sample_reports_XI.zip]
and i've use the "JRC_Display_Connection_Info"on a xml to display all of the properties.
After i've make a program for change the datasource in the case of "xml http" database.
Changes the DataSource for a specific Table from XML
@param clientDoc              The reportClientDocument representing the report being used
@param reportName     "" for main report, name of subreport for subreport, null for all reports
@param tableName     name of table to change.  null for all tables.
@param username       The DB logon user name
@param password       The DB logon password
@param xmlURL          The Http(s) XML URL
@param xsdURL          The Http(s) Schema URL
@throws ReportSDKException
     public void changeDataSourceXML(ReportClientDocument clientDoc,
                    String reportName, String tableName,
                    String username, String password,String xmlURL,String xsdURL) throws ReportSDKException {
                PropertyBag propertyBag = null;
          IConnectionInfo connectionInfo = null;
          ITable origTable = null;
          ITable newTable = null;
          // Declare variables to hold ConnectionInfo values.
          String SERVER_TYPE = "XML e servizi Web";
          String CONVERT_MULTIVALUE_TO_TABLE="false";
          String DATABASE_DLL = "crdb_xml.dll";
          String HTTPS_SCHEMA_URL= xsdURL;
          String HTTPS_XML_URL= xmlURL;
          // Declare variables to hold database User Name and Password values
          // I've see by "JRC_Display_Connection_Info" that USERID_HTTPS_SCHEMA
          // and USERID_HTTPS_XML's value is equal to username value
          String DB_PASSWORD = "";
          String DB_USER_NAME = username;
          String USERID_HTTPS_SCHEMA=username;
          String USERID_HTTPS_XML=username;
          // Obtain collection of tables from this database controller
          if (reportName == null || reportName.equals("")) {
               Tables tables = clientDoc.getDatabaseController().getDatabase().getTables();
               for(int i = 0;i < tables.size();i++){
                    origTable = tables.getTable(i);
                    if (tableName == null || origTable.getName().equals(tableName)) {
                         newTable = (ITable)origTable.clone(true);
                         newTable.setQualifiedName(origTable.getAlias());
                         // Change connection information properties
                         connectionInfo = newTable.getConnectionInfo();
                         // Set new table connection property attributes
                         propertyBag = new PropertyBag();
                         // Overwrite any existing properties with updated values
                         propertyBag.put("Http(s) Schema URL", HTTPS_SCHEMA_URL);
                         propertyBag.put("Http(s) XML URL", HTTPS_XML_URL);
                         propertyBag.put("Server Type", SERVER_TYPE);
                         propertyBag.put("UserID Http(s) XML", USERID_HTTPS_XML);
                         propertyBag.put("Database DLL",DATABASE_DLL );
                         propertyBag.put("Convert Multivalue to Table", CONVERT_MULTIVALUE_TO_TABLE);
                         propertyBag.put("UserID Http(s) Schema", USERID_HTTPS_SCHEMA);
                         connectionInfo.setAttributes(propertyBag);
                         // Set database username and password
                         connectionInfo.setUserName(DB_USER_NAME);
                         connectionInfo.setPassword(DB_PASSWORD);
                         // Update the table information
                         clientDoc.getDatabaseController().setTableLocation(origTable, newTable);
But i don't know why if i call:
System.out.println(reportClientDoc.getDatabaseController().getDatabase().getTables().getTable(0).getConnectionInfo().getAttributes().toString());
on my
ReportClientDocument reportClientDoc = new ReportClientDocument();               
reportClientDoc.open(ReportName, 0);
after changeDataSourceXML i've one more attribute than those defined by me called PreQEServerType that take the Server_Type value.
I think that is the cause of the output error of my program on the export method
ByteArrayInputStream byteArrayInputStream = (ByteArrayInputStream)reportClientDoc.getPrintOutputController().export(ReportExportFormat.PDF);
