javax.servlet.http package in Apache Karaf 2.3.0

I've installed Apache Karaf 2.3.0. One of my bundles that needs to be installed in it uses classes from javax.servlet.http package. When I try to install the bundle it gives me the error message:

karaf@root> ERROR: Bundle com.groupgti.esb.purge [207] Error starting mvn:com.groupgti.esb/esb.purge/1.0.0 (org.osgi.framework.BundleException: Unresolved constraint in b

javax.servlet.http package is exported from: mvn:org.apache.geronimo.specs/geronimo-servlet_2.5_spec/1.1.2 system bundle. The problem is that its version is 2.5 but and my bundle requires at least 2.6.0. Is there a workaround or something to update the geronimo-servlet to the higher version that would be compatible with my bundle? (This is the system bundle).

Additional information:

CXF Version: 2.7.0
Camel Version 2.10.2

EDIT:

I forgot to mention the important thing. I also updated CXF to 2.7.0 version and CXF is the one which is introducing the dependency of Servlet 3.0. This is the graph from dependency tree:

Maybe will give you some idea on how get around this? The only thing that I could think of is to go back to CXF 2.6.x.

If your bundle really needs something newer than 2.5, you may have problems running it on Karaf 2.3.0. Karaf 2.3 uses Jetty 7.6.7 which is based on Servlet 2.5. It doesn't support any of the newer Servlet 3 based API's and such. You can upgrade the servlet-api bundle and it MAY work, but if your bundle/app uses any of the Servlet 3 functionality, it will likely not work.

Karaf 3 will be upgrading to Jetty 8.1 which does support the Servlet 3 stuff. Any help testing that and getting that out would be greatly appreciated by the Karaf community. :-)

Do you really need to use geronimo servlet spec ? Try replacing it with this:

    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>javax.servlet-api</artifactId>
        <version>3.0.1</version>
        <scope>provided</scope>
    </dependency>
