Firebird embedded and JBuilderx java application
 
 I am very close to getting Firebird embedded working with JBuilder
 the DataModule wizard can see data
 the setconnection throws no exceptions
 But when I try to open a table [QueryDataSet in my program it throws a
 com.borland.dx.dataset.DataSetException



      dDriver = "org.firebirdsql.jdbc.FBDriver";
      durl = "jdbc:firebirdsql:embedded:C:\\a\\emFirebird\\T21";
      database1.setConnection(new com.borland.dx.sql.dataset.ConnectionDescriptor(durl, dUname, dpass, false,  dDriver));
   

      
===========================================      
com.borland.dx.dataset.DataSetException: Resource Exception. I/O error for file CreateFile (open) ""
Error while trying to open file
null
Reason: I/O error for file CreateFile (open) ""
Error while trying to open file
null
============================================
[nb its a QueryDataSet, not a 'file' that I am trying to open]

If I omit the "embedded"  ie:
              durl = "jdbc:firebirdsql:C:\\a\\emFirebird\\T21";
              
              
I get:
============================================
              

com.borland.dx.dataset.DataSetException: Resource Exception. Unable to complete network request to host "C".
Reason: Unable to complete network request to host "C".

============================================




Note: the setconnection throws no exception even when the url points to a directory  which does _not_ contain my fdb database
The exceptions arise when I try to open a QueryDataSet
