Error while using jersey-client in osgi - No generator was provided
Register hk2-locator and javassist as bundles on your OSGi framework.
Jersey uses hk2-locator to find services on OSGi.
Add the following archives from the Jersey-ext-directory to your classpath:
hk2-api-*.jar
hk2-locator-*.jar
hk2-utils-*.jar
javax-inject-*.jar
jersey-guava-*.jar
I had this same issue and I could finally solve it by starting my bundle which uses Jersey to publish an endpoint at level 2 in the Felix Framework (OSGi-5.4). I am not sure why, but seems like the HK2-Locator dependencies:
- hk2-api-2.4.0-b10.jar -> Level 1
- hk2-locator-2.4.0-b10.jar -> Level 1
- hk2-utils-2.4.0-b10.jar -> Level 1
- org.apache.servicemix.bundles.javax-inject-1_2.jar -> Level 1
- jersey-guava-2.22.1.jar -> Level 1
need to start first before the bundle who uses them:
- your-bundle-1.0.0.jar -> Level 2
Once you set your bundle to start on this new level then make sure to execute frameworklevel 2
in Felix console to start the bundles under that level. Restart the framework and it will work.
