Question

I have this code

import com.crystaldecisions.reports.sdk.ReportClientDocument;
...

ReportClientDocument rpt =  new ReportClientDocument();
    rpt.open(reportPath+fileName, 0);
    rpt.getDatabaseController().logon(DBConnect.getUsername(), DBConnect.getPassword());
    Tables tables = rpt.getDatabaseController().getDatabase().getTables();

    for(int i=0; i< tables.size(); i++){
        System.out.print(i);
        ITable table = tables.getTable(i);

        IConnectionInfo connInfo = table.getConnectionInfo();

        PropertyBag innerProp = connInfo.getAttributes();
        innerProp.clear();

        PropertyBag propertyBag = new PropertyBag();
        propertyBag.put("Server Type", "JDBC (JNDI)");
        propertyBag.put("Database DLL", "crdb_jdbc.dll");
        propertyBag.put("Connection String", DBConnect.getConnectionString());
        propertyBag.put("Database Class Name", "com.mysql.jdbc.Driver");
        propertyBag.put("Use JDBC", "true");
        propertyBag.put("Server Name", DBConnect.getServer());
        propertyBag.put("Generic JDBC Driver Behavior", "No");
        propertyBag.put("URI", "!com.mysql.jdbc.Driver!jdbc:mysql://"+DBConnect.getServer()+":"+DBConnect.getPort()+"/"+DBConnect.getDatabase()+"!ServerType=29!QuoteChar=`");

        connInfo.setAttributes(propertyBag);
        connInfo.setKind(ConnectionInfoKind.SQL);

        table.setConnectionInfo(connInfo);
        rpt.getDatabaseController().setTableLocation(table, tables.getTable(i));

What Im trying to do is to open a report and pass the connection info to that report so that I can dynamically change the database of the report but for some reason it is not working and the report still produces the information from the database that it was initially set up. Can someone please tell me what I did wrong? This is a swing application and I am using crystal reports XI. Btw Im using com.crystaldecisions.reports.sdk.ReportClientDocument instead of com.crystaldecisions.sdk.occa.report.application.ReportClientDocument because when I use the other one, I get a cannot find server error. Please help.

To switch connection at runtime you can use this:

IConnectionInfo oldConnInfo = new ConnectionInfo();
IConnectionInfo newConnInfo = new ConnectionInfo();

// If this connection needed parameters, we would use this field.   
com.crystaldecisions.sdk.occa.report.data.Fields pFields = null;

try{
    // Assign the old Connection info to the reports current info
    //DatabaseController dbController = rptClient.getDatabaseController();
    oldConnInfo=dbController.getConnectionInfos(null).getConnectionInfo(0);
    com.crystaldecisions.sdk.occa.report.lib.PropertyBag boPropertyBag1 = new com.crystaldecisions.sdk.occa.report.lib.PropertyBag();
    boPropertyBag1.put("JDBC Connection String","...");
    boPropertyBag1.put("Server Type","...");
    boPropertyBag1.put("Database Type","...");
    boPropertyBag1.put("Database Class Name","...");
    boPropertyBag1.put("Use JDBC","...");
    boPropertyBag1.put("Connection URL","...");
    boPropertyBag1.put("Database DLL","...");
    // Assign the properties to the connection info
    newConnInfo.setAttributes(boPropertyBag1);
    // Set the DB Username and Pwd
    newConnInfo.setUserName("...");
    newConnInfo.setPassword("...");    
    // The Kind of connectionInfos is SQL
    newConnInfo.setKind(ConnectionInfoKind.SQL);

    // set the parameters to replace.
    // The 4 options are:
    // _doNotVerifyDB 
    // _ignoreCurrentTableQualifiers 
    // _mapFieldByRowsetPosition 
    // _useDefault  
    int replaceParams = DBOptions._ignoreCurrentTableQualifiers + DBOptions._doNotVerifyDB;
    // Now replace the connections
    dbController.replaceConnection(oldConnInfo, newConnInfo, pFields, replaceParams);
    }catch(ReportSDKException rse){
    ...
    }

Pass appropriate values in the above code snippet. Sorry that this uses com.crystaldecisions.sdk.occa.report APIs.

Hope this helps…
