Hi,

I am at a loss as to how to get the REST service example working with Virgo for Tomcat 3.7.0.RELEASE.

When I try to install the bundle I'm getting the following error:
[2017-05-28 11:32:31.470] ERROR deployer-recovery            org.eclipse.virgo.medic.eventlog.default                         DE0002E Installation of bundle 'org.eclipse.virgo.samples.recipe.restservice' version '0.0.1.SNAPSHOT' failed. org.eclipse.virgo.kernel.osgi.framework.UnableToSatisfyBundleDependenciesException: Unable to satisfy dependencies of bundle 'org.eclipse.virgo.samples.recipe.restservice' at version '0.0.1.SNAPSHOT': Cannot resolve: org.eclipse.virgo.samples.recipe.restservice

I have copied the following files from the gradle cache to "repository/ext":
jackson-core-2.1.2.jar
jackson-annotations-2.1.1.jar
jackson-databind-2.1.2.jar

I first tried them in "repository/usr" but spring was complaining about a missing class:

I have the feeling that I am missing something pretty basic but this is the first time that I have tried using REST.

I have it working now, and the reason it wasn't working is because the version of the fasterxml bundles has to be in the range [2.6.4,3) .

I downloaded the 2.8.8, copied that into "repository/usr" and everything worked.

So when it was in "repository/ext" the range exception "0.0.0", basically it's existence wasn't correct.

And when it was in "repository/usr" the class not found exception was also incorrect, the optional version dependency in "org.springframework.webmvc" was unresolved.

Glad you managed to get the sample up and running.

I'll try to reserve a few cycles to update the sample to 3.7.0.RELEASE and our Gradle/Docker approach like the newer recipes.

Thanks for keeping us in the loop.

Hi Florian,

essentially everything worked out of the box as it was. The only difficulty was finding out what was causing the version issue.

I think that the framework should report a different error other than ClassNotFoundException, especially when the class is available. It would be reasonable to expect that equinox or virgo report that a bundle supplying the "optional" dependency in required version range " [2.6.4,3)" couldn't be resolved.

I'm not sure if that is an equinox based or a virgo based class loader/resolver issue.
