Re: [Springframework-developer] JCA support

[Thierry T. <te...@ya...>]

Hi Juerguen,

Great news ;-)
I will checkout the JCA support from cvs as soon as
possible...
I see too that the JCA sample is in cvs but, I think
that it doesn't use classes of the main sources. I
will refactor it to use it.
To finish, do you want that I update the documentation
of the JCA support with your improvements?
Cheers,
Thierry
