Re: IBM's AS/400 toolbox for JAVA

["Luther Ananda Miller" <LAM_SoftTel@xxxxxxx>]

Roger,

Thanks for your explanation! I was under the false understanding there were
separate "ADO" drivers as well. I have CA V3R2M0 and have searched the
documentation multiple times for any info on using ADO never found any .. so
I assumed the OLD DB stuff was something lower level. And then someone on
the as400 newsgroups mentioned ADO 2.0 support in CA Express, so I got it
all mixed up.

Does that mean it is not possible to use the OLE DB stuff from CA V3R2M0
with ADO 2.0? And to use it with ADO 1.1, howdo you specify the ADO drivers
in the connection string? We have started using ADO 2.0 to access our
AS/400's data but so far just with ODBC data sources we have created.

Thanks,

Luther

The
