Camel with Karaf

Hi everyone,

I have some problems getting a Bundle, which is using Camel, to run on my Karaf (Version 2.3.0, Camel Version 2.13.0). I think this is because I'm doing something wrong with the Import Statements in the Manifest file. This is the pom.xml of my Bundle:

<?xml version="1.0" encoding="UTF-8"?>

</project>

And here is the route and context I am initiliazing when the bundle is started (I'm using camel-blueprint):

    <!-- The camel context which will hold the routes -->
    <camelContext id="context" xmlns="http://camel.apache.org/schema/blueprint">
        <routeContextRef ref="newElementContext"/>
    </camelContext>

    <routeContext id="newElementContext" xmlns="http://camel.apache.org/schema/blueprint">
        <route id="newElement">
            <from uri="direct:insertElement"/>
            <to uri="sql:insert into orders (:#id, :#item, :#amount, :#description, false)"/>
        </route>
    </routeContext>

 I have installed the camel, camel-core, camel-spring, camel-blueprint and camel-sql features so that normally the referenced packages should be imported. However, I'm facing a NullPointerException when starting the bundle:

I'm quite sure that this is really about the camel karaf components, since the org.apache.camel.blueprint.handler.CamelNamespaceHandler is involved in the StackTrace.
Can anybody help me out here?

Greetings,
Pascal

Re: Re: Re: Camel with Karaf

Posted by Achim Nierbeck <bc...@googlemail.com>.

Hi,
hotdeployment and updateing of bundles containing routes in general need to
be handled with care ;)
The camel-core bundle usually takes care of managing the routes available
within all other bundles, if you update another bundle, the old route is
still referenced from the core bundle and therefore still available and
will collide with a new "hot-deployed" route. For this the camel-core
bundle needs to be refreshed for it to have a new bundle-wiring to the new
available routes and to ditch the reference to the "old" ones.

regards, Achim

Aw: Re: Re: Camel with Karaf

Posted by Pascal Klink <pa...@web.de>.


Hi everyone,
 
I finally found the issue.
The good news first: The problem is not the camel route and context intialization using blueprint. The Problem was using the hot deploy feature of karaf. I only recieved the exceptions when I overwrote the bundles in the hot deploy folder in order to let karaf load them again. When I removed the bundles from the hot deploy folder first and then copied the new versions of the bundles into the hot deploy folder - everything works just fine.
Now the "bad" one: I have absolutely no idea why these Exceptions only occur when I directly overwrite the bundles in the hot deploy feature. So if this is a common flaw of the hot deploy feature in karaf and somebody could explain it to me - I would be very thankful for that.
 
Greetings,
Pascal

Aw: Re: Re: Camel with Karaf

Posted by Pascal Klink <pa...@web.de>.

Hi everyone,

I think I've narrowed the root of the problem down to blueprint. I took a working example from the internet and reworte the route which was built in Java Code in Blueprint XML and voila - another NullPointerException. I'll now try to rewrite my own route in Java and only use the camelcontext instantiation in blueprint.

@Charlie
I started the SQL component in the same bundle the route is created in but I think your idea is really good because it decouples the route from the database details. Thanks for that!

Greetings,
Pascal

Re: Re: Camel with Karaf

Posted by Charlie Mordant <cm...@gmail.com>.

Hi,

For some component, you have to export them as Osgi services, then
referencing in your bp.xml as the prefix you use it in your route.


I would do so for the SQL component:

	<reference id="sql" interface="org.apache.camel.Component"
		availability="mandatory" filter="(component-type=sql)">

Regards,

Aw: Re: Camel with Karaf

Posted by Pascal Klink <pa...@web.de>.

Hi Christpoh,

I'm running on JDK 7. Other bundles are starting up perfectly when having no dependencies to camel so there aren't any other issues around except this one (I hope I answered b) as you expected - I was not excatly sure what you meant with the question).

Greetings,
Pascal

Re: Camel with Karaf

Posted by cemmersb <ce...@gmail.com>.

Hi Pascal,

one quick question, are you using JDK 8.0?

I’m facing a similar behaviour when running Karaf on JDK 8.0 - without any Camel:

Can you please double check the following:

a) Which JDK are you running at?
b) Are there any other, similar issues around?

Best,

Christoph
