All Implemented Interfaces:

public class DataSourceConfiguration extends Object implements Serializable, Comparable
A DataSourceConfiguration is a description of a data source, that can be used by an i-net Clear Reports report.
We differentiate between a data source that use a JDBC driver and a data source that use a com.inet.report.database.DataFactory 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( Engine.NO_EXPORT );
 eng.setReportFile("c:/sample.rpt");
 Datasource ds = eng.getDatabaseTables().getDatasource(0);
 ds.setDataSourceConfigurationName("myFirstDSC");

    • setValidationQuery

      public void setValidationQuery(String validationQuery)
      Sets the SQL query which should be executed to validate the connection defined by this DataSourceConfiguration. Usually Connection.isClosed() will be called to check if the connection is still valid. In some circumstances it is possible that this returns true although the connection is invalid. (e.g. the network connection to the database is still established but the database server does not accept any further query). In this case the connection can be checked with a simple SQL query. If this query can be executed without any error the connection should be valid.
      Parameters:
      validationQuery - The SQL query which should be executed for validation of the database connection.
      Since:
      7.0
