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 :
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 JDBC driver / database connection:
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");
