RE: General HiveMind questions
Thank you. I found out that HiveMind was indeed throwing an exception and it
was being logged ... I'd missed it. And, when I googled the exception string I
found the same solution. I was going to post the answer but thanks to your
quick response, I don't need to.

No...I think it's .. So, if you hivemodule.xml file has
CustomTeamPageAdmin as the id and a service id of "jndiLookup" you would
reference the service as "CustomTeamPageAdmin.jndiLookup" .
The things you see in svn rely on package="" being set on the element,
it's a convenience to eliminate verbose package strings when constructing
services..
For JNDI, I think the Virtual Library application has an example of that. It
even uses jboss so you should feel right at home.

You almost sound like you've been "forced" to use Tapestry. Ah well.

Well, HiveMind does support "bean" services, but they're not recommended really
(at least not by me). Interface-based services are preferred.
Anyway, if you have to use a bean, all you have to do is use the bean class as
the interface when defining your service. You can set your "parameters"
by autowiring (if they're supposed to be references to other HiveMind
services) or using XML inside the hivemodule.xml file. If you're using
tapestry-autowire (or Tap4.1), then all you have to do is declare an abstract
getter of the same type as your bean class and Tapestry will automatically look
it up for you.
