Dependency conflicts when adding Axis2 to large project.

Hello,

We have a multi-module Maven project that we are adding Axis2 to as a
dependency.

The axis2-kernel-1.6.2.pom has a dependency:

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

This seems to conflict with a pre-existing project dependency:

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

What is the difference between the servlet-api artifact and the
javax.servlet-api artifact? Also why doesn't the axis2-kernel, servlet-api
dependency specify a version?

Thank you for any help!
