Hi all,

We have been asked to help in a project that is using ejb2 on was5.0.We need
 to setup development environments and were wondering if we could use WAS6.1
 and still be backwardly compatible with was5.0?

We haven't used a lot of ejb2 stuff before but the project makes use of simp
le session and entity beans with CMP. Are the deploymnets descriptors etc th
e same between the versions or are there enough differences to be a problem?

regards

Mark

EJB apps written to WAS 5.0 are fully upward-compatible with WAS 6.1.  It is
 not even necessary to rerun the deploy tool; just install your app from 5.0
 and run.

thanks for the info. I haven't worked much with websphere before. If I carry
 out modifications and run the app on  was6.1 and then delpoy to was5.0 will
 there be anything I need to be aware of? i.e is was5.0 upwardly compatible 
with 6.1? I won't be taking
advantage of any of the new advanced features of 6.1.

thanks again.

regards

Well...you'd asked whether 5.0 was upward-compatible with 6.1, and it is.  I
'm assuming you're asking now whether 6.1 is backward-compatible with 5.0, a
nd that's not officially supported.  (Actually, 5.0 itself isn't officially 
supported anymore.)

That said, as long as your apps don't use any features that aren't available
 in 5.0, they will probably run OK even if built using a 6.1 environment...b
ut it's not guaranteed to work, so you'd want to test carefully.
