Title: RE: DB2/400 for EntityBeans(CMP)

In the directory

\QIBM\ProdData\HTTP\Public\jt400\lib

There is a smaller version of the jt400, containing only the access classes
(jt400.jar also contains swing components)

jt400access.zip

Thanks Gilles,
                As u said i faced only one constraint in AS400 side, the
required physical file should be journalized and to find this constraint on
my own cost 1 day, oh. I will be happy if any one gives URL where i can find
the related info like what are the steps to be followed.
                Further i am not able to find another jar file containing
only the access files. Please clarify me about this.

Vijay.
