Construct a Web Application From Multiple Bundles
Hi,
I've been using/learning/experimenting using Apache Karaf and Pax Web 3.X to
deploy a web application.
What I would like to do now is be able to split my web application across
several OSGi bundles, similar to what Virgo Snaps
<https://www.eclipse.org/virgo/documentation/virgo-documentation-3.5.0.RELEASE/docs/snaps-guide/htmlsingle/virgo-snaps-guide.html>
allows to be done.
As far as I am aware, although I can make the Java code visible to other
Java code in another bundle, web content/pages is not. I want to structure
my bundles with a parent bundle provides a 'base' web-page frame work into
which is can load/display web pages/content from child bundles if/as they
become available. Based upon my understanding above, this means that the
parent bundle needs to be able to access content in it's child bundles.
My question is, is this possible to do this with Karaf and Pax web as they
stand? So far I believe that each web bundle is in isolation to one another
i.e. no visibility.

Hi,
anything special of the war file you just droped in there?
could you open an issue for this, makes it easier to track.

pax web error on bundle install

The first time I drop my bundle into deploy it does not start correctly.
The following error is the one that I am getting. After a karaf restart
though everything starts and works fine.

Can someone direct me to the changes to the HTTP Service which make this possible? How did they handle the getResource method with a shared HTTPContext? We're investigating exactly this scenario now.

Hi,
never tried to run Pax-Web 4 with Karaf 3.0.2 but if you do it you won't have the web and http commands available.
AFAIK Karaf 4 and JPA shouldn't be of an issue, you might need to make sure you have the right version of it installed though.
You should give it a try :-)

Re: Construct a Web Application From Multiple Bundles
Posted by jtkb <ka...@avionicengineers.com>.
Hi Achim,
I'm having a few problems understanding how I can create a web-fragment
bundle which includes JSF. I can create something based upon the Pax-Web
samples project 'war-jsf', with the POM similar and I just use
<web-fragment> tags instead of <web>. The bundle deploys however when I
go to view the pages I get the raw JSF i.e. it's not been processed.
I've looked at the web-fragment example too and this is a little
different as it uses JSP and not JSF. It also builds a JAR instead of a
WAR but this shouldn't really make much difference?
I'm a little confused how to structure a bundle to deploy JSF pages as a
web-fragment, any pointers?
Thanks

hehe, yeah sometimes it might seem that way.
It's a pleasure to help people to get on track :)
btw. the mailinglist I had in mind (as I didn't realize it's the karaf one
we are talking on right now)
is the ops4j mailinglist [1].
The thread is actually this one: [2]

Hi Achim,
Thanks for your reply. I did think it might be a little difficult and
especially as I've only a small amount of experience with web
applications etc.
I'll think on the answers you provided and search the mailing list
archive for the thread you mentioned. I appreciate yours and all those
involved with Karaf help and advice when I as a user get a problem. In
fact I sometimes wonder if you get to go to sleep as you sometimes seem
to answer at all hours of the day (and night!)
Regards
Kerry

Re: Construct a Web Application From Multiple Bundles
Posted by Achim Nierbeck <bc...@googlemail.com>.
Hi, Kerry,
ouch you want to use JSF ... since JSF is doing stuff a lot different then
all other web-based applications, especially lots of classforname search.
This will make it much more complicated
Besides that, it might be doable, I just don't use JSF a lot so we might go
into the undiscovered-country here ;-)
Thinking about this, I could see different ways of getting there.
One way, start with a wab and extend it with web-fragments, this is the way
it'll work in any Servlet3 container and should work for Pax-Web too.
("should" could mean, there might be a missing feature in pax-web which I'm
not aware of right now)
The other way would require to register the JSF Listener either through the
webcontainer service or as a service so the Whiteboard-Extender can pick it
up.
Again I think due to the nature of JSF/JSPs and Taglibs this might be a
bigger hassle. BUT I've seen a thread on this mailinglist where one was
doing something similar and registering resources as such, with some
tweaking I think. So it can be done.
regards, Achim

Hi Achim,
You mentioned previously that I could use Pax-Web WebContainer to
possibly achieve 'loadable' child OSGi bundles (contain web pages etc)
into a Parent/base page.
I've been looking at the 'helloword-wc' sample to see how to use
WebContainer. I should have mentioned I want to use JSF in child bundles
and I assume this is possible as I can call
WebContainer.registerServlet() with an instance of
javax.faces.webapp.FacesServlet instead? Is there anything else I
particularly need to do using JSF (other than having JSF support
installed)? I did wonder if I need to call WebContainer.registerJsps() too?
Regards
Kerry

Hi,
never tried to run Pax-Web 4 with Karaf 3.0.2 but if you do it you won't
have the web and http commands available.
AFAIK Karaf 4 and JPA shouldn't be of an issue, you might need to make sure
you have the right version of it installed though.
You should give it a try :-)

Just to clarify, I meant Pax-Web 4 in Karaf 3.0.2.

Re: Construct a Web Application From Multiple Bundles

Hi Achim,
Thanks for your reply, and apologies for not replying. I have had a few
problems with the mailing list and forum website but I think I have those
resolved.
Do I need to move to Karaf4 and Pax-Web 4 to do this ? For example can I use
Pax-web for in Karaf 3.0.2?
The only reason I ask is that I also need JPA which I know works in 3.0.2
but experienced problems with it in 3.0.3. If there are no problems with JPA
in Karaf 4 then I can certainly look to moving to it.

Hi,
as per OSGi spec this isn't possible for war or wab bundles.
But you can do something like this with Karaf4 and Pax-Web 4 if you use the
whiteboard extender of Pax-Web and/or the Pax-Web WebContainer (an enhanced
HttpService).
With this version you are able to register a HttpContext as a shared
Context, and therefore you are able to register web-resources to this
shared HttpContext.
