Facing problem while changing the database at runtime

Question

hi everyone,
Before posting this thread, i have gone through the various posts addressing the problem....but still iam unable to get the solution for this problem.
The report has been generated in one system, so the database properties (connection string....) are hardcoded in the report file...
Now when iam trying to change the database, it is still connecting to the system where the report file was created.
I have tried the changeDatasource() method, but it didnot worked....
here is the code for changeDatasource() method
public static void changeDataSource(ReportClientDocument clientDoc,
                String reportName, String tableName,
                String username, String password, String connectionURL,
                String driverName,String jndiName) throws ReportSDKException {
        PropertyBag propertyBag = null;
        IConnectionInfo connectionInfo = null;
        ITable origTable = null;
        ITable newTable = null;
        // Declare variables to hold ConnectionInfo values.
        // Below is the list of values required to switch to use a JDBC/JNDI
        // connection
        String TRUSTED_CONNECTION = "false";
        String SERVER_TYPE = "JDBC (JNDI)";
        String USE_JDBC = "true";
        String DATABASE_DLL = "crdb_jdbc.dll";
        String JNDI_DATASOURCE_NAME = jndiName;
        String CONNECTION_URL = connectionURL;
        String DATABASE_CLASS_NAME = driverName;
        // The next few parameters are optional parameters which you may want to
        // uncomment
        // You may wish to adjust the arguments of the method to pass these
        // values in if necessary
        // String TABLE_NAME_QUALIFIER = "new_table_name";
        // String SERVER_NAME = "new_server_name";
        // String CONNECTION_STRING = "new_connection_string";
        // String DATABASE_NAME = "new_database_name";
        // String URI = "new_URI";
        // Declare variables to hold database User Name and Password values
        String DB_USER_NAME = username;
        String DB_PASSWORD = password;
        System.out.println("DB_USER_NAME......."+DB_USER_NAME);
        System.out.println("DB_PASSWORD......."+DB_USER_NAME);
        // Obtain collection of tables from this database controller
        if (reportName == null || reportName.equals("")) {
            Tables tables = clientDoc.getDatabaseController().getDatabase().getTables();
            System.out.println("Tables in reports........"+tables.size());
            for(int i = 0;i < tables.size();i++){
                origTable = tables.getTable(i);
                System.out.println("origTable........"+origTable.getQualifiedName());
                if (tableName == null || origTable.getName().equals(tableName)) {
                    newTable = (ITable)origTable.clone(true);
                    // We set the Fully qualified name to the Table Alias to keep the
                    // method generic
                    // This workflow may not work in all scenarios and should likely be
                    // customized to work
                    // in the developer's specific situation. The end result of this
                    // statement will be to strip
                    // the existing table of it's db specific identifiers. For example
                    // Xtreme.dbo.Customer becomes just Customer
                    newTable.setQualifiedName(origTable.getQualifiedName());
                    System.out.println("newTable........"+newTable.getQualifiedName());
                    // Change properties that are different from the original datasource
                    // For example, if the table name has changed you will be required
                    // to change it during this routine
                    // table.setQualifiedName(TABLE_NAME_QUALIFIER);
                    // 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("Trusted_Connection", TRUSTED_CONNECTION);
                    //propertyBag.put("Server Type", SERVER_TYPE);
                    propertyBag.put("Use JDBC", USE_JDBC);
                    propertyBag.put("Database DLL",DATABASE_DLL );
                    propertyBag.put("JNDI Datasource Name",JNDI_DATASOURCE_NAME );
                    propertyBag.put("Connection URL", CONNECTION_URL);
                    propertyBag.put("Database Class Name", DATABASE_CLASS_NAME);
                    //propertyBag.put("Server Name", SERVER_NAME); //Optional property
                    // propertyBag.put("Connection String", CONNECTION_STRING); //Optional property
                    // propertyBag.put("URI", URI); //Optional property
                    connectionInfo.setAttributes(propertyBag);
                    // Set database username and password
                    // NOTE: Even if the username and password properties do not change
                    // when switching databases, the
                    // database password is *not* saved in the report and must be set at
                    // runtime if the database is secured.
                    connectionInfo.setKind(ConnectionInfoKind.SQL);
                    connectionInfo.setUserName(DB_USER_NAME);
                    connectionInfo.setPassword(DB_PASSWORD);
                    // Update the table information
                    clientDoc.getDatabaseController().setTableLocation(origTable,newTable);
Also i tried with replaceConnection() method...........it displayed the report, but with not column names and data
need help regarding.......

Answer 1

In the report i have two tables.............so before changing the database properties for each table iam printing their names.
The names are dispalyed correctly.......but once i set the table location...i.e through the following method..
clientDoc.getDatabaseController().setTableLocation(tables.getTable(i),newTable);
every time i can see only one table i.e. properties are set for the first table ........and each time the properties are being set for the first table only.....i dont no what is happening to the rest of the tables..
I have posted the method in the above post.....can any one please trace out the problem
Note: when i comment the following code, i can see all the tables
clientDoc.getDatabaseController().setTableLocation(tables.getTable(i),newTable);
when i uncomment it, i can see only first table repeating every time...
