There is a speculation that Web Services are the ideal technology for
solving enterprise application integration problem. While some propose
that web services offer cheap EAI solutions thereby possibly reducing
the scope for current EAI solutions like TIBCO, webMethods etc. On the
other hand, some others think that web services are too new a
technology with incomplete standards to be able to displace EAI
solutions. While some others believe web services will co-exist with
EAI solutions. Need to choose from the three opinions.

Hi! Would a list of articles providing arguments for Web Services and
EAI be enough as a legitimate answer? Just let me know. :)

Clarification of Question by eternal_searcher-ga on 21 Apr 2003 21:52 PDT

If the articles just talk about what Web Services are or what EAI is
about, they won't help.
If the articles give arguments explaining why Web Services or EAI is
the preferred technology/approach..that would help.
Thanks
