IBIRelational tables with java

Hi Guys,

i'm trying to recieve data from the BI with the BI Java SDK. I have the following code:

com.sapportals.portal.ivs.cg.IConnectorGatewayService cgService = (com.sapportals.portal.ivs.cg.IConnectorGatewayService)PortalRuntime.getRuntimeResources().getService(IConnectorService.KEY);
	
ConnectionProperties cp = new ConnectionProperties(request.getLocale(), request.getUser());    
connection = cgService.getConnection(<Connectorname>, cp);

IBIRelational rel =((IBIConnection)connection).getRelational();
List tables = rel.getObjectFinder().findTable(null,"%");

After executing I recieve only 5 tables. But I need the content of other tables.

How can I access tables with the bi java sdk?

Greetings.
