AS/400 iSeries .Net Connection problem

Greetings,
I have am using the (AS/400) iSeries .NET provider inside a VB application.  All works great with the code I will paste below except for SQL statements that join files from more then 1 Lib.    i.e.

select * from TSTDTA/myfile1 f01 inner join JACK/myfile2 f02 on f01.keyfield = f02.keyfield

That statement works fine when run directly on the iSeries but not when I use it with my function, i get an error.
 "SQL5016 Qualified object name myfile2 not valid."

 I have the following connection string...
_ConnString = "DataSource=999.999.999.999;DefaultCollection=TSTDTA;UserID=user;Password=pass"

and use the following function to fill a table in a dataset.

    Public Function fillDataSet(ByVal strSQL As String, ByVal strTableName As String, ByVal myDataset As DataSet) As Boolean
        Dim conn As New iDB2Connection
        Dim myda As iDB2DataAdapter
        conn.ConnectionString = _ConnString ' & ";Allow Zero Datetime=false"
        If IsNothing(strSQL) Or strSQL = "" Then
            Return False
        End If
        If IsNothing(strTableName) Or strSQL = "" Then
            Return False
        End If
        Try
            conn.Open()
            myda = New iDB2DataAdapter(strSQL, conn)
            myda.SelectCommand.CommandTimeout = 0
            If myDataset.Tables.Contains(strTableName) Then
                myDataset.Tables(strTableName).Clear()
            End If
            myda.Fill(myDataset, strTableName)
        Catch myerror As iDB2Exception
            Logerror("myData.filldataset", "Error:", myerror, False)
            Return False
        Catch myerror As Exception
            Logerror("myData.filldataset", "Error:", myerror, False)
            Return False
        Finally
            If conn.State <> ConnectionState.Closed Then conn.Close()
        End Try
        Return True
    End Function

I don't konw AS/400. However, the qualified names in SQL Server/T-SQL 92 are of the form database.owner.tablename. You might try this and see if it helps.
