I'm trying to run a simple camel test route which reads files from a
directory, puts them into an ActiveMQ queue, and another one reads the
files from the queue and writes them to another directory.
I took examples/camel-osgi and started building on top of it.
beans.xml:
<route>
<from uri="activemq:queue:someq"/>
<to uri="file:d:/servicemix-files/out" />
</route>
<route>
<from uri="file:d:/servicemix-files/in"/>
<to uri="activemq:queue:someq"/>
</route>
<bean id="activemq"
class="org.apache.activemq.camel.component.ActiveMQComponent"
depends-on="my-broker">
<property name="brokerURL" value="tcp://localhost:61616" />
</bean>
<broker:broker id="my-broker" useJmx="false" persistent="false"
brokerName="localhost">
<broker:transportConnectors>
<broker:transportConnector uri="tcp://localhost:61616"/>
</broker:transportConnectors>
</broker:broker>
At first I got a bunch of osgi "unresolved constraint in bundle
camel-osgi errors". After a while of trial and error I ended up with
following changes:
features.xml:
<feature name="examples-camel-osgi" version="4.2.0">
<feature version="2.2.0">camel</feature>
<feature version="5.3.0">activemq</feature>
<feature version="4.2.0">camel-activemq</feature>
<bundle>mvn:org.apache.servicemix.examples/camel-osgi/4.2.0</bundle>
</feature>
pom.xml:
<artifactId>maven-bundle-plugin</artifactId>
...
<Import-Package>*,org.apache.camel.component.jms,org.apache.activemq.xbean,org.apache.camel.osgi,org.apache.activemq.camel.component,org.apache.activemq.broker,org.apache.activemq.pool</Import-Package>
But still I do get a ClassNotFoundException when I try to deploy the feature:
Caused by: org.springframework.beans.factory.CannotLoadBeanClassException:
Error loading class
[org.apache.activemq.camel.component.ActiveMQComponent] for bean with

....
Caused by: java.lang.ClassNotFoundException:

1) What do I need to do to fix this ClassNotFoundException
2) How can I know what I need to configure into features.xml, pom.xml
import-packages and dependencies when I want to use camel and it's
activemq component from servicemix? Is this information documented
somewhere? Doing it by trial-and-error gets frustrating pretty fast...
