I see.
Great, I got the dummy example working on FuseESB 4.3
1) added camel-activemq to example's feature
(apache-servicemix-4.3.1-fuse-00-00-features.xml)
<feature name="examples-camel-osgi" version="4.3.1-fuse-00-00">
<feature>camel-activemq</feature>
<feature version="2.6.0-fuse-00-00">camel</feature>
<bundle>mvn:org.apache.servicemix.examples/camel-osgi/4.3.1-fuse-00-00</bundle>
</feature>
2) did not touch pom.xml maven-bundle-plugin confifuguration at all
3) configured a few routes:
<route>
<from uri="file:c:/projects/esb-files/jms-start" />
<setBody>
<simple>
Moving File to queue(file: ${file:name}, timestamp:
${date:now:hh:MM:ss.SSS})
${in.body}
</simple>
</setBody>
<to uri="activemq://events" />
</route>
<route>
<from uri="activemq://events" />
<setBody>
<simple>
Receiving file from queue:[${in.body}]
</simple>
</setBody>
<to uri="file:c:/projects/esb-files/jms-end" />
</route>
Transformed messages are popping in the target directory as expected.
Still a bit confused about what was the problem with ServiceMix 4.2,
what I should have done differently - should I have e.g. configured
maven-bundle-plugin differently - and are there perhaps some camel
components that are not yet "preinstalled" in ServiceMix 4.3 that I
may need to fight with at later point, if need to use them presents
itself...
I any case, a good start, thanks for assisting!
