These are 'good' errors :) They mean that you are attempting to load a bundle, but the bundle needs (requires) some packages that are not available.
For example: ERROR: Bundle org.apache.felix.webconsole [1] Error starting jndi:/localhost/osgi-demo/WEB-INF/bundles/org.apache.felix.webconsole-4.2.0-all.jar (org.osgi.framework.BundleException: Unresolved constraint in bundle org.apache.felix.webconsole [1]: Unable to resolve 1.0: missing requirement [1.0] osgi.wiring.package; (&(osgi.wiring.package=org.osgi.service.http)(version>=1.2.0)(!(version>=2.0.0)))) This message means that you are trying to start bundle org.apache.felix.webconsole-4.2.0-all.jar but it is missing some dependencies. If we read the docs here: http://felix.apache.org/site/apache-felix-web-console.html we find that it needs 'a running implementation of the OSGi Http Service Specification.'. The docs list some suggestions: Apache Felix HTTP Service. PAX Web Service. Equinox HTTP Service implementation. So you will have to find one of those bundles and make sure it is deployed as well. The 'good' thing about these errors is that Felix' dependency mechanism is working as expected. It is refusing to start a bundle for which it cannot satisfy all the required dependencies. This in contrast to NoClassDefFound / ClassNotFound errors, which are runtime errors indicating that you did something wrong so Felix could not protect you against trying to load classes that are not available. So, check out all these errors. Look where the packages mentioned in the error messages are supposed to be coming from. More often than not these are supposed to be coming from some other bundle. Then just make sure to deploy that bundle as well and the error should be solved. E.G in the previous error message, the text (&(osgi.wiring.package=org.osgi.service.http)(version>=1.2.0)(!(version>=2.0.0)))) indicates that the package org.osgi.service.http is needed (and version should be greater or equal to 1.2.0 and not greater or equal to 2.0.0).
