]
Tadayoshi Sato updated CAMEL-12873:
-----------------------------------
Description:
There was a configuration example for {{HttpRegistry}}, which is introduced by
CAMEL-3549, under
{{tests/camel-itest-osgi/src/test/resources/org/apache/camel/itest/osgi/servlet/}}.
The test itself was removed probably because it depended on deprecated Spring
DM, but the use case CAMEL-3549, which is to use a CamelServlet instance across
OSGi bundles, exemplified by the test should be still valid and maintained.
However, with the latest Camel when deploying the attached example
({{camel-example-servlet-httpregistry-blueprint.zip}}) to Karaf it fails to
deploy throwing the following error:
