java.lang.ClassNotFoundException: org.glassfish.hk2.Module from GlassFish server during deploy

Question

I'm trying to build a REST webservice and I'm using the web.xml build architecture, with pre-3.0 servlets. This is my web.xml:

    <servlet>
        <description>JAX-RS endpoint - JLWS04Serv</description>
        <display-name>JLWS04Serv</display-name>
        <servlet-name>JLWS04Serv</servlet-name>
        <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
        <init-param>
            <param-name>javax.ws.rs.Application</param-name>
            <param-value>com.psp2.ws4.JLWS04Serv</param-value>
        </init-param>
        <init-param>
            <param-name>org.glassfish.jersey.internal.ProcessingException</param-name>
            <param-value>com.psp2.ws4.JLWS04Serv</param-value>
        </init-param>
        <init-param>
            <param-name>org.glassfish.hk2.api</param-name>
            <param-value>com.psp2.ws4.JLWS04Serv</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

The problem is that when I try to deploy, the server show this error:

java.lang.NoClassDefFoundError: org/glassfish/hk2/Module

I tried searching for the JAR but I didn't find a single hk2 library that has that directory or the Module class.
