Persistent helper objects on server side
Morning all,
This is a slightly noob-ish question that reflects my lack of
experience with Java web apps in general.
I have some objects for database access and business logic which I
want to create on deploying my service WAR. I want these to hang
around within the CXF servlet so they can by called on by my service
implementation classes.
Where do I put the code to initialize them? And how do I call them
from my services?
A pointer to a relevant example would be ideal, unless it's just a
two-line answer.
Thanks in advance,
Andrew.
(PS... The objects in question use Guice for dependency injection, if
anyone has any extra tips about linking CXF to Guice then fire away,
otherwise I'm sure I can figure that part out from a general example.)

I didn't think of that. Nice one. I'm sure there's a 'proper' way with
servlet context listeners or something, but this will get me off the
ground quickly.

I'm very familiar with the later version already, it got me started
with JAX-WS and helped me choose between CXF and Metro. In short it's
been indispensable, so thanks :-)
Andrew.

For a rather primitive example, you can use a static { } block in your
service implementation bean as shown here[1] in Step #6. It's a start at
least. But note that other portions of the below blog entry (not covering
the static {} ) have since been heavily updated, with the new link at the
top of [1].
HTH,
Glen

Yep. The Bus has add/get extension things that you can use to
store/retrieve objects. All users of that bus can share those things.

Thanks, I'll look into the bus option. I guess the advantage of this
over Glen's static initializer is that you could share objects on the
bus between different services?
Bit reluctant to go for a Spring solution as there's only one coder on
this project -- me -- with a total of 0 days Spring experience.
Cheers,
Andrew.

I guess the "proper" answer for us at this point would be to define the
objects in Spring and let spring inject them into your service beans and
stuff. That's more or less the normal way we do it.
Another option it to inject the Bus into your service with:
@Resource
Bus bus;
And save things on the bus that you could retrieve later.
