(dirty solved): NSDates, NSTimestamps and the Java-bridge

Gracias Joaquin!
Thanks Art, Seejo, Dirk!

I'd found a solution... dirty but it works.
Basically I have to assgin the qualifier in the Java side.
I hope Apple is doing something to get better Cocoa/EO... and the 
Java-Bridge!

Here is the code:

- (NSArray*)facturasDe:(id)eo desde:(NSCalendarDate*)desde
{
     [desde setCalendarFormat:@"%d %m %Y"];

     id nst = [Util nst:[desde description]]; //this is an NSTimestamp 
created by Util.java

     [Util setAuxiliaryQualifierTo:[dgFacturas dataSource]:eo:nst];
     [dgFacturas fetch:self];

     return [dgFacturas displayedObjects];
}


     public NSTimestamp nst(String dateString){
         NSTimestampFormatter formatter=new NSTimestampFormatter("%d %m 
%Y");
         ParsePosition pp = new ParsePosition(0);
         NSTimestamp 
myNSTimestamp=(NSTimestamp)formatter.parseObject(dateString,pp);

         return myNSTimestamp;
     }

     public void setAuxiliaryQualifierTo(EODatabaseDataSource ds, 
Facturas eo, NSTimestamp nst){
         NSMutableArray nsma = new NSMutableArray();
         nsma.addObject(eo.folio());
         nsma.addObject(nst);

         EOQualifier eoq =  
EOQualifier.qualifierWithQualifierFormat("cliente=%@ and fecha>=%@ and 
estado>0",nsma);
         ds.setAuxiliaryQualifier(eoq);
     }
