Just want to use HttpServletRequest in my Rest service.
Get the follow error page when try to do GET request:

java.lang.LinkageError: loader constraint violation: loader (instance of org/apache/felix/framework/BundleWiringImpl$BundleClassLoader) previously initiated loading for a different type with name "javax/servlet/http/HttpServletRequest"

I use apache-karaf-4.1.5 as a container, apache-cxf for JAX-RS implementation. And I marked javax.servlet-api as provided in pom.xml:

<dependency>

    <groupId>javax.servlet</groupId>

    <artifactId>javax.servlet-api</artifactId>

    <version>3.1.0</version>

    <scope>provided</scope>

</dependency>



<dependency>

    <groupId>org.apache.cxf</groupId>

    <artifactId>cxf-rt-frontend-jaxrs</artifactId>

    <version>3.1.7</version>

</dependency>

So.. any thoughts to avoid this error and makes this work properly ?

Thanks!
