Class DataSourceConfiguration

java.lang.Object
  com.inet.report.config.datasource.DataSourceConfiguration

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable

public class DataSourceConfiguration
extends java.lang.Object
implements java.io.Serializable, java.lang.Comparable

A DataSourceConfiguration is a description for a data source, that can be used by an i-net Clear Reports report.
We differentiate between a data source use a JDBC driver and a data source use a com.inet.report.Database extended class. In last case the report data will be set directly by Database class. In first case i-net Clear Reports use the settings of this data source configuration to establish a JDBC connection to a database server. Then it requests the data via SQL statements.
At execution time of the report, i-net Clear Reports creates the connection to the database, based on this settings.

If i-net Clear Reports runs inside of an application server, it will try to find a connection via JNDI.
The path to receive the DataSource from application server is : "java:comp/env/jdbc/"+DataSourceConfiguration.
If no data source was found, i-net Clear Reports creates the connection by itself.

Typical a DataSourceConfiguration will be created with the GUI but you can also create it via API.
Example for a DataSourceConfiguration based on a Database class:

 DataSourceConfiguration dsc = DataSourceConfigurationManager.createDataSourceConfiguration( "myFirstDSC", DataSourceConfigurationManager.TEMPORARY_PREFERENCES );
 dsc.setDatabaseClassname( "com.company.DatabaseImpl" );
 dsc.setDriverLibrary( "c:/lib/reportclasses.jar" );//you can also set an URL
 dsc.save( DataSourceConfigurationManager.TEMPORARY_PREFERENCES ); //-> manager->store
 

Samples for own Database classes can be found in sample library at:
samples.jdbc.DatabaseClassUsableInDesigner
samples.jdbc.DataWithExternalResultSet
samples.jdbc.DataWithoutJDBC

Example for a DataSourceConfiguration based on a JDBC driver / database connection:

 
 DataSourceConfiguration dsc = DataSourceConfigurationManager.createDataSourceConfiguration( "myFirstDSC", DataSourceConfigurationManager.TEMPORARY_PREFERENCES );
 dsc.addProperty( DataSourceConfiguration.PROPERTY_DRIVER_CLASSNAME, "com.inet.tds.TdsDriver" );//MS SQL Server driver from i-net software
 dsc.addProperty( DataSourceConfiguration.PROPERTY_URL, "jdbc:inetdae7" );
 dsc.addProperty( DataSourceConfiguration.PROPERTY_USER, "sa" );
 dsc.addProperty( DataSourceConfiguration.PROPERTY_PASSWORD, "xxxx" );
 dsc.addProperty( "host", "localhost");        //a driver specific property
 dsc.addProperty( "database", "northwind" );   //a driver specific property
 dsc.save( DataSourceConfigurationManager.TEMPORARY_PREFERENCES ); //-> manager->store
 
 ...
 
 create a new report based on this datasource configuration
 
 Engine e = RDC.createEmptyEngine();
 Datasource ds = e.getDatabaseTables().createDatasource("myFirstDSC");
 TableSource ts = ds.create...

 switch an existing Datasource to a DataSourceConfiguration
 
 Engine eng = new Engine();
 eng.setReportFile("c:/sample.rpt");
 Datasource ds = eng.getDatabaseTables().getDatasource(0);
 ds.setup("myFirstDSC");
