Problem with starting web-app during startup
Hi,
I'm using karaf-2.2.4 and want to start a web application (with wicket) when
karaf starts. I've defined a feature that is listed under featureBoot in the
org.apache.karaf.features.cfg.
Unfortunately I get the following WARN during startup and the web app is not
started. However if I start the feature manually from the console it starts
without a problem. What am I missing? Is there anything I've to wait for? If
yes, how can I configure it?
This is my feature:
<feature name="monitoring-server-web" version="${project.version}">
<feature version="${apache-karaf-version}">war</feature>
<feature version='${project.version}'>monitoring-server-core</feature>
<bundle>mvn:org.apache.wicket/wicket/${wicket-version}</bundle>
<bundle>mvn:org.apache.wicket/wicket-ioc/${wicket-version}</bundle>
<bundle>mvn:org.apache.wicket/wicket-spring/${wicket-version}</bundle>
<bundle>mvn:org.apache.wicket/wicket-extensions/${wicket-version}</bundle>
<bundle
start-level='70'>war:mvn:com.*somepackage*.server/monitoring-server-web/${project.version}/war?Webapp-Context=web-console</bundle>
</feature>
And this is the log from startup:
2011-10-26 11:05:14,471 DEBUG
[org.apache.karaf.features.internal.FeaturesServiceImpl] (Thread-6) Checking
war:mvn:com.*somepackage*.server/monitoring-server-web/2.0.3-SNAPSHOT/war?Webapp-Context=web-console

Hi,
It works fine if the web-app is installed after startup, however I was not
able to get it working if it was installed as boot-feature, even with
changing the start-levels.
Thanks for all the reponses!
Regards
Andi

Hi Andi,
Try the following sequence, i.e. basically starting from scratch to make
sure you have no funny leftovers:
1) Shutdown Karaf
2) Deleting your data directory
3) Start Karaf, making sure that your custom features descriptor is *not* on
the bootstrap list.
4) Install the http, web and war features
5) Install your custom feature

Hi Andi,
yeah Raul is right and the relevant information is right here ;)
the startlevel of the Pax Url war bundle is 60 and probably your bundle
containing your war is the same,
that's why it's not possible to run right away from start. You need to make
sure your own Bundle is of startlevel higher then 60.

Raul,
Not sure if I get you right .... these are the only bundles with 'war' in
the name. But I don't know which contains the war protocol.
[ 82] [Active ] [ ] [ ] [ 60] OPS4J Pax Web -
Extender - WAR (1.0.6)
[ 85] [Active ] [ ] [ ] [ 60] OPS4J Pax Url - war
(1.2.8)

Andi

Andi,
Can you send us relevant line from the output of the "la" command showing
the war protocol? Let's see what the bundle runlevel is...
I experienced a similar issue installing the classpath: protocol and later
realised that I needed to decrease the bundle's runlevel so that it's made
available in the container at an earlier stage during startup.
Regards,
Raúl.

Hi Ioannis,
Ok, I removed the war from the feature of my web-app and added it to boot
features, but the problem still exists.
I guess it is because I've added the feature of my web-app to the boot
features as well ... so I think I've to remove my web-app from boot features
and have it deployed at a later stage. But I'm not sure what would be the
best for that? Do I have to create a kar and put it into the deploy folder?
Would this solve my problem?
Regards,
Andi

Hi Andi,
You can have war feature and a bundle using the war protocol inside the same
feature. The reason is that the war protocol is made available to the
container once it is installed and will not be available at the time of the
resolution.
What you can do is to add the war feature in the boot features before your
own feature. I think that this will work.

Hi JB,
Yes, I can see the following line before the line with the error in the
logfile:
2011-10-27 12:51:50,912 INFO
[org.apache.karaf.features.internal.FeaturesServiceImpl] (Thread-6)
Installing feature war 2.2.4
In Karaf-2.2.3 I haven't seen this error but my web-application was not
started during startup, too.
If I install the web-application bundle manually and restart karaf it is
started correctly, so maybe there is a problem with installing during
startup.
Regards
Andi

Hi Andi,
did you install the war feature ?
The war: protocol is provided by Pax Url War which is in the war feature:
features:install war
