Hi,
I want to test Camel routes in Karaf. I use Pax-Exam to run Karaf.
For older Karaf and Camel versions, I found a blog article by J.B. Onofre
which shows how one can use CamelTestSupport to do that.
I got it working on JDK 8 for an older combination of Camel, Karaf and
PaxExam with numerous adjustments (see links below). But when I switch to
the current versions (Camel 2.24.2, Karaf 4.2.7, Pax-Exam 4.13.1), the
CamelTestSupport
setup fails, complaining with ClassNotFoundException:
org.apache.camel.util.jndi.CamelInitialContextFactory.
When I disable the CamelTestSupport.setUp() method by overriding it with an
empty method, I can see that the camel-core feature is present:
assertTrue(featuresService.isInstalled(featuresService.getFeature("camel-core")));
I have also tried to import the org.apache.camel.util.jndi package into the
probe bundle. The package gets exported by the camel-core bundle jar, at
least its MANIFEST.MF says so.
@ProbeBuilder
public TestProbeBuilder probeConfiguration(TestProbeBuilder probe) {
probe.setHeader(Constants.IMPORT_PACKAGE,
"*,org.apache.camel.util.jndi");
return probe;
}
The import appears to work, at least I get no import error during test
execution.
Why can the test bundle not find the CamelInitialContextFactory?
I have created a clone of J.B. Onofre's Github example which fixes the JDK
8 issues and another one with recent versions which demonstrates the
problem.
Works: Karaf 2.4 with Camel 2.12.1 on JDK 8
<https://github.com/dschulten/blog-camel-blueprint/tree/karaf24-jdk8>
Fails: Karaf 4.2.7 using Camel 2.24.2
<https://github.com/dschulten/blog-camel-blueprint/tree/karaf4-paxexam4>.
Here is my stack overflow question with all the details and other attempts
I have made:
