Karaf Camel and
All,
I'm just getting started with Karaf and am having a small issue. It seems
blueprint has replaced or is replacing spring. I'm trying to use blueprint
but most examples show spring.
Using Karaf 2.2.2
I want to use camel to send a file from one machine to another. A file gets
created on machine A and camel is supposed to moved it to machine B.
On machine A camel: polls for a new file then writes it's contents to a jms
queue.
On machine B camel: reads the file from a jms queue and writes it to a local
directory.
Sounds simple!
Camel reads the file well enough, but does not appear to be writing it to
the jms queue. The activemq web console never shows any activity.
Here is the xml file I am placing in the karaf deploy directory on machine
A. Do I have this right?
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0">
<camelContext xmlns="http://camel.apache.org/schema/blueprint">
<route>
<from uri="file:/home/karaf?noop=true" />
<to uri="jms:queue:biofiles" />
<!-- If I do this, the file does appear in standard out: <to
uri="stream:out" /> -->
</route>
</camelContext>
</blueprint>
I have karaf setup and working on both machines. I have installed the
following camel and activemq features:
- activemq
- activemq-blueprint
- activemq-web-console
- camel
- camel-blueprint
- camel-jms
Thanks in advance.

Posted by Geoffry Roberts <ge...@gmail.com>.
I solved the problem with activemq-camel 5.5.0 by simply dropping the file:
"activemq-camel-5.5.0.jar" into the deploy directory. I also deleted the
file: "localhost-broker.xml". After these two actions, the following
blueprint (See below.) succeeds in placing a bit of text on the queue of
the local activemq broker. i.e. my machine A. Now the challenge is to read
from said queue and write the message to standard out. It doesn't seem to
be working. (See below for the blueprint from machine B.)
Blueprint file on machine A:
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0">
<bean id="jms"
class="org.apache.activemq.camel.component.ActiveMQComponent">
<property name="brokerURL" value="tcp://machineA:61616" />
</bean>
<camelContext xmlns="http://camel.apache.org/schema/blueprint">
<route>
<from uri="timer:test?period=5000" />
<setBody>
<constant>Ave Mundus!!</constant>
</setBody>
<to uri="jms:queue:ave" />
</route>
</camelContext>
</blueprint>
**********************
Blueprint file on machine B:
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0">
<bean id="jms"
class="org.apache.activemq.camel.component.ActiveMQComponent">
<property name="brokerURL" value="tcp://machineA:61616" />
</bean>
<camelContext xmlns="http://camel.apache.org/schema/blueprint">
<route>
<from uri="jms:queue:ave" />
<to uri="stream:out" />
</route>
</camelContext>
</blueprint>

gcr, activemq-camel is correct, but I can't get 5.5.0 to install either at
the moment...5.4.2 works fine
though...

Re: Karaf Camel and
Posted by Geoffry Roberts <ge...@gmail.com>.
Thanks for the help so far, but I still have a few issues.
When I add the <bean id="jms" ...> as Claus advised, I get a log entry that
says that karaf can't find "org.apache.activemq.camel.component". To remedy
this, I attempted to do the following at the karaf client CLI:
karaf@root> osgi:install -s mvn:org.apache.activemq/activemq-camel/5.5.0
The response is a complaint that the URL cannot be resolved.
Am I on the right track? if not, from where can I get
"org.apache.activemq.camel.component"?
Thanks

Re: Karaf Camel and
Posted by Claus Ibsen <cl...@gmail.com>.
Hi
Yeah you need to Camel which JMS Broker to use.
I assume you are using Apache ActiveMQ which can be embedded easily,
in one of the machines.
So basically you just have to add a <bean id="jms" ...> as shown here
http://camel.apache.org/activemq
<bean id="jms"
class="org.apache.activemq.camel.component.ActiveMQComponent">
<property name="brokerURL" value="tcp://somehost:61616"/>
</bean>
And then you need to set the brokerURL to the IP of the target broker.

Thanks for the quick response.
Did you mean I should define a connection factory pointing to machine B? I
ask this because on machine A camel and activemq are in the same jvm.

You need to define a connection factory, jms component etc if you are connecting to an external entity.
