Java Example from the 2.0 RC2 SDK Section 12.2.2 "Adding and editing 
DataSources" does not work. 
Indeed the Object returned from 
com.sun.star.sdbc.DatabaseContext.createInstance() does not support 
com.sun.star.frame.XStorable interface 
 
This interface is necessary as according to the dev guide [quote]"Before data 
sources can be registered at the database context, they have to be stored with 
the com.sun.star.frame.XStorable interface. The method storeAsURL should be 
used for that purpose."[/quote]  
 
Executing the code below returns NULL : 
XStorable store = ( XStorable)UnoRuntime.queryInterface(XStorable.class, xDs); 
 
Also querying the datasource object's property "DatabaseDocument" throws an 
UnsupportedPropertyException : 
 
// "reference"  is returned by createInstance() on the DatabaseContext  
 XPropertySet properties = UnoRuntime.queryInterface(XPropertySet.class, 
object)  
 Object document = properties.getProperty("DatabaseDocument");  
  
The above code throws an UnsupportedPropertyException. 
 
The "DatabaseDocument" property should give access to the 
com.sun.star.frame.XStorable interface according to some OOBasic examples
