I'm glad you figured it out. Seems like there's a general problem with name
conflicts in servlet names, web-app names, service names and maybe other things.
If anyone else has observed this sort of behavior, please email me at
[EMAIL PROTECTED], or just reply to the list with as much detail as you can
provide.
This is a problem I noticed recently when I defined an alias for a servlet that
conflicted with a service name (for example, a servlet alias of "scheduler" will
conflict with the default service named "scheduler"). For now the workaround is
to keep names of all these things unique. But I realize common names soon
become scarce, especially when deploying complicated applications with many
components.
