Assigning Wars To Ports And Subdirectories?

Hello,

I am not sure whether this is a PAX Web question, or a Karaf question but:

(1) If I install a war/wab file, is there any way of making it available on
certain ports? For example, I would probably want the Karaf console and
Active MQ console on a separate port to my application wabs/wars (as my
wabs/wars may be visible through a firewall whilst Karaf console should not
be).

(2) Any way of installing wars (which are not OSGi wabs) to subdirectories?
In tomcat I could do this by adding a "#" as part of the war name (e.g.
hosting#fred.war could be accessed by http://hostname/hosting/fred.war).
There isn't a similar feature in Karaf/PAX Web, is there?

thanks in advance,
Gareth

HI Gareth,

yeah the reverse Proxy is a great functionality and I use this
Architectural design quite often. Makes your applications much more
safe :-)

Hello Achim,

The virtual hosts feature is probably exactly what I need.

As you suggested, for now I will use Apache as a reverse proxy to hide those
services I don't want to make publicly available.

thanks,
Gareth

Hi Gareth,

to me this seems like a similar requirement as a "virtual-host" setting.
I'm planning on supporting jetty-web.xml in the next release of Pax Web.

till that is available I just suggest to use different context paths and
put a Apache Webserver
in front of the Karaf server for providing these services.

regards, Achim

Hello JB,

I didn't realize I could do this for non-wab wars:

> install
> webbundle:file:./MyWebApp.war?Bundle-SymbolicName=com.mycompany.mywebapp&Web-ContextPath=/hosting/com.mycompany.mywebapp&<additional
> custom parameters defined by me>

...so I guess that helps part of my problem.

I still hope to find a way to restrict specific web applications to certain
ports though...

Thanks again.

regards,
Gareth

Re: Assigning Wars To Ports And Subdirectories?

Posted by Gareth <ga...@gmail.com>.

Hello JB,

I knew about the Web-ContextPath in the MANIFEST.MF. I was just hoping there
was a way to be able to do this without making all wars into wabs :). For
these wars, could I perhaps create my own bundle listener, make it run
before Pax Web (is that possible?) and go add the Web-ContextPath into the
MANIFEST.MF before PAX Web reads it (is that possible?)?

I also gave your two suggestions a try:

(1) With the first suggestion, I got more ports configured for Jetty, but
all my wars were still available on all ports.

(2) I added the file install configuration (I see now two file install
configurations in the Karaf console). I can now add files from the new
location...though web applications are still installed in the same dir.

There is no way to run multiple Pax Web instances in the same Karaf
instance, is there (with the ability to explicitly assign each war to a
specific instance?)?

Thank you very much for the help.

regards,
Gareth

Hi Gareth,

1/ currently, Pax Web support the webapp context path using the 
following OSGi statements:

   <Web-ContextPath>/myapp</Web-ContextPath>
   <Webapp-Context>/myapp</Webapp-Context>

When you install the HTTP feature, it installs a jetty.xml file in the 
etc folder.
In this jetty.xml file, you can define several port number for the 
embedded jetty server.

Create a new Connector in the jetty.xml with an ID, like:

<Call name="addConnector">
   <Arg>
     <New id="my" 
class="org.eclipse.jetty.server.nio.SelectChannelConnector">
       ...
       <Set name="port">5340491</Set>
       ...
     </New>
   </Arg>
</Call>

After, to associate the webapp with the Configured server, try to create 
a etc/context.xml file containing:

<Configure class="org.eclipse.jetty.webapp.WebAppContext">
   <Set name="contextPath">/myapp</Set>
   <Set name="connectorNames">
     <Array type="String">
       <Item>my</Item>
     </Array>
   </Set>
</Configure>

Without guarantee, I never tried this before :)

2/ for the directory, you can create a new file in etc, for instance 
etc/org.apache.felix.fileinstall-war.cfg containing:

felix.fileinstall.dir=${karaf.base}/war
felix.fileinstall.tmpdir=${karaf.data}/webapp
felix.fileinstall.poll=1000

Could you try this ?

Regards
JB
