I'm trying to create a bundle using HttpService for register Servlet using maven-bundle-plugin.

The pom.xml of the project is:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

In the configuration of the maven-bundle-plugin you have to specify all the packages you need to import.

In your case it should be:

   <plugin>
    <groupId>org.apache.felix</groupId>
    <artifactId>maven-bundle-plugin</artifactId>
    <extensions>true</extensions>
    <configuration>
     <instructions>
      ...
      <Import-Package>org.osgi.service.http, org.osgi.framework;version="1.0.0", javax.servlet, javax.servlet.http</Import-Package>
     </instructions>
    </configuration>
   </plugin>
