Application servers, other than WebSphere

Hi all.

Has anyone successfully run an appserver, other than WebSphere, on the
AS/400/iSeries?  I see from the archives that there has been some use of
JBoss -- indeed we have made some attempts in that area; but it's not
clear to me whether anyone has used the full J2EE suite: EJBs, JMS, JCA
resource adaptors, and so on.

As well as JBoss, I gather that Orion (http://www.orionserver.com/) may
be an option.

I'd be interested to hear of any experience anyone has had (of these or
any others).

As a bit of background, we are a software house, and we are in the
process of redeveloping one of our applications to take advantage of
J2EE technologies.  As we have a large AS/400 and iSeries client base,
obviously we intend to include WebSphere as one of the platforms we
target.  However, we are concerned that WebSphere may push the price up
over what our smaller clients will be willing to pay, and so want to
consider possible alternatives.

Thanks in advance.

Cheers,

Martin.
