Hi Marc
You are absolutely right - it is possible to use frontend server
and use pax-web as backend server. But in this case pax-web
in any serious production use can be used only as backend +
if you have 15 domains you will manage 15 ports.

Here are my two cents
Regarding the whiteboard-extender, I was actually thinking of moving this
into the webcontainer, because due to the whiteboard-dto spec those two are
closely related anyways. My idea was to deprecate the (upcoming)
WhiteboardManager-service right away in order to merge those two modules in
a 7.0 release. So that might solve one pain-point.
But another question is: do we need to rewrite everything in order to get a
feature which might no be needed? Without knowing the business-case behind
registering multiple contexts with the same name in different
virtual-hosts, I still think that there are much cheaper alternatives:
everything today moves away from heavy-installations (AppServers) in favor
of dedicated containers. With OSGi and Pax-Web you can easily spawn
multiple VMs, and have some proxy/webserver in front which manages the
site/domain to look like one.

Sounds like a good and interesting idea ...
Right now only from the top of my head:
The Pax-Web Runtime and therefore the different Implementations aren't
made for this right now. So this would need a complete rewrite of how we're
handling it. Another point would be how would web and white-board extender
work with it. We could think about wiring those two closer to the core.
Never the less an application deploying servlets will always need to add
the virtual host environment, working with defaults could take care of that.
We could consider to start this with a complete rewrite of Pax-Web and
therefore aim for a 7.0.
BUT ... I fear I won't have enough time to takle this. Considering the
amount of time I spent in the past and about what it would take to have all
the functionalities of Pax-Web re-written, and especially with my $dayJob +
Family.

Honestly, if this is to be fixed, I think Pax Web should support Managed
Service Factory, and instantiate separate virtual host services according
to a provided configuration. That configuration should contain which WAB(s)
goes into that virtual host, together with any other virtual host
configuration.
To me, that seems to be the right solution forward, maintains OSGi
compatibility, doesn't introduce new config args on WABs and doesn't treat
"one domain" different than another.
I think the tricky bit is to make the default case and the MSF
instantiations play nicely with each other, but that is an design
implementation detail at this stage.

I analyzed situation again and I am sure I am right. How I explain this
- if *only*
web-contextpath is used then all war bundles (wabs) are inside one
domain.
Obvious if you need more then one domains (virtualhosts) this
limitation is
unpleasant. So I am sure that when bundle is deployed it must have
*two*
settings:
Layer one - virtualhosts (plural)
Layer two - web-contextpath.
In this case the deployer has all the advantages. He can create N sites
And inside every virtualhost he can make N contexts if he needs.
I am sure that this functionality must be developed. Pax-web is great
product
and with such functionality it will have all main functionality of a
good web server.
I would be glad to hear others opinion about such New Feature.

Ok Achim.
I understood the situation. You know the architecture of pax-web well.
Could you say - how difficult
it can be to make some extender (plugin etc) to link wabs not to
web-contextpath but to virtualhosts
and to make them all work with one port like it is in usual web
servers (for example apache).
Please, note I don't care about specification - I care about normal
work.

I never said Pax-Web is a complete replacement for GlassFish,
it's a WebContainer for OSGi environments, which fulfills the OSGi
spec.
It uses Jetty, Undertow or Tomcat to do so. AND it gives you most of
the benefits of those underlying servers in the
same way. If you're not satisfied because you expect something
different. I'm sorry to hear
but nothing we can do about.

Well, in that case try to use GlassFish again.
GlassFish uses a complete different strategy.

Something is wrong here. I worked with glassfish. Everything starts
with glassfish domain.
In one domain you usually have one http connector and one https
connector. After that in
one domain you can have multiple virtual hosts. When you deploy
osgi bundle you
in manifest have Web-ContextPath and VirtualServers. So you can
have N sites
(example.com, boo.org, blablabla.net) with WebContextPath / and it
is not necessary
to create new connectors for new ports.
I know it well, because I remember it took me some time to make it
work.
And I was very glad because it is easy to work with one port then
with N.
Now you suggest me to go back and again work with N ports. I am
shocked and killed.

Hi,
yes, you can only have one Web-ContextPath per WAB. "/" is
especially tricky since you can also have HttpService servlets listening on
that one.

Hi Achim
Thank you for the links, I wil study them now. So, do I
understand it right -
accroding to specs I can have only one bundle with
web-contextpath / for one port ?

Achim, I understand you, but why? If the domains are different
why must I change web-contextpath? For example, lets suppose
I have five different sites on one osgi and for every site I
have
separate wab (which is logical) and every wab has only one
context
- /. It is normal situation - take a look at any web server.

So in that case you need to make sure of different

Hi Achim,
Yes, you are right. The same web-contextpath in both bundles:
/
But it seems to be a bug because in bundle A I have
jetty-web.xml
<Configure
class="org.eclipse.jetty.servlet.ServletContextHandler">
<Set name="virtualHosts">
<Array type="java.lang.String">
<Item>example.com</Item>
<Item>www.example.com</Item>
</Array>
</Set>
</Configure>
and in bundle B I have jetty-web.xml
<Configure
class="org.eclipse.jetty.servlet.ServletContextHandler">
<Set name="virtualHosts">
<Array type="java.lang.String">
<Item>foo.example.com</Item>
<Item>www.foo.example.com</Item>
</Array>
</Set>
</Configure>

Hi all
It may seem to be funny question but I have the following
situation. I
have two war bundles A and B.
When I start and install only bundle A - it works ok. When
I start and
install only bundle B it works ok.
When I try to install both of them always only the first
works. The
servlet in the second bundle is not
instantiated. I tried to add
<load-on-startup>0</load-on-startup> to
servlet config
in web.xml but it didn't help.
Any ideas? Does anyone try to deploy more then one war
bundle on the same
osgi framework with pax-web 6.0?
Best regards,
