Extending the Data Warehouse Tutorial NumbersTableDescriptor


Ralph Kelkenbe (4612) | asked Sep 30 '08, 10:18 a.m.
Hi im working through the tutorial "Extending the Data Warehouse" and having some problems with the chapter "Designing the Tables ".

I have implemented the code and i get the error that the statement "SELECT" doesnt exist on continent.setAggregationKind(AggregationKind.SELECT);
and
number.setAggregationKind(AggregationKind.SELECT);

'AggregationKind.SELECT cannot be resolved'


import com.ibm.team.datawarehouse.common.AggregationKind;

import com.ibm.team.datawarehouse.common.FieldFlags;
import com.ibm.team.datawarehouse.common.FieldKind;
import com.ibm.team.datawarehouse.common.IFieldDescriptor;
import com.ibm.team.datawarehouse.service.AbstractTableDescriptorFactory;
import com.ibm.team.datawarehouse.service.ISnapshotService;
import com.ibm.team.datawarehouse.service.common.ICommonSnapshotService;
import com.ibm.team.repository.common.TeamRepositoryException;


public class NumbersTableDescriptorFactory extends AbstractTableDescriptorFactory{

@Override
/*protected void createTableDescriptors() throws TeamRepositoryException {
// TODO Auto-generated method stub

}*/

protected void createTableDescriptors() throws TeamRepositoryException {
createNumbersStorageFact();
}

private void createNumbersStorageFact() {
IFieldDescriptor id = createFieldDescriptor(
ISnapshotService.FACT_ID_COLUMN, FieldKind.LONG,
FieldFlags.DEFAULT);
IFieldDescriptor timeId = createFieldDescriptor(
ISnapshotService.TIME_ID_COLUMN, FieldKind.LONG,
FieldFlags.QUERYABLE);
IFieldDescriptor continent = createFieldDescriptor(
INumbersSnapshotService.CONTINENT_COLUMN,
FieldKind.STRING, FieldFlags.QUERYABLE | FieldFlags.PARAMETER);
IFieldDescriptor number = createFieldDescriptor(
INumbersSnapshotService.NUMBER_COLUMN,
FieldKind.INTEGER, FieldFlags.DEFAULT);
timeId.setReference(getTableDescriptor(
ICommonSnapshotService.SNAPSHOT_NAME,
ICommonSnapshotService.TIME_DIMENSION));
continent.setAggregationKind(AggregationKind.SELECT);
[color=red]number.setAggregationKind(AggregationKind.SELECT);[/color]
createTableDescriptor(
INumbersSnapshotService.NUMBERS_FACT_TABLE,
new IFieldDescriptor[] { id, timeId, continent, number },
id);
}



}

i worked through the tutorial and now i'm wondering how i can check if the jazzserver and rtc is working with the plugin.
If i look into the WebUI on Reports & Administer Data Warehouse i cannot find the case "NUMBERS_SNAPSHOT" on the combo box, but i have named it on the plugin.xml

I'm using the JazzServer-06-RTC10-Maximal.launch. to launch my plugin, but i still cant find the service.
