Answer 1

I recently bumped into this problem. It was caused by a library providing an old implementation of javax.ws.rs.core. I fixed it as follows:

    <dependency>
        <groupId>org.apache.axis2</groupId>
        <artifactId>axis2-jaxws</artifactId>
        <version>1.6.2</version>
        <scope>runtime</scope>
        <exclusions>
            <!-- Causes java.lang.NoSuchMethodError: javax.ws.rs.core.Response$Status$Family.familyOf(I)Ljavax/ws/rs/core/Response$Status$Family; -->
            <exclusion>
                <groupId>javax.ws.rs</groupId>
                <artifactId>jsr311-api</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

Can you take a look at libraries catalogue of your JBoss instance and remove all implementations of JAX-WS? To me it seems they conflict with the Jersey you bundle in your WAR-file.

Edit:

Actually I guess you need to resolve JAX-WS version conflict between your server and web application. Method familyOf you are missing in Response.Status.Family was introduced in Java 7 but is missing from Java EE 6. So find Java EE 6 compatible Jersey version or upgrade the server.

And if later Maven will cause problems, then for the real kick, there's also

mvn dependency:tree

and

<dependency>
...
        <exclusions>
            <exclusion>...</exclusion>

I encountered a similar error. "java.lang.NoSuchMethodError: javax/ws/rs/ClientErrorException.validate(Ljavax/ws/rs/core/Response;Ljavax/ws/rs/core/Response$Status$Family;"

Root cause: web service performance tester invoke the web service using script without passing in correct request body. missing a "/" in the path url of web service call is another case.

when you see this validation error, that means some major error already happened, this noSuchMethodError is only a minor byproduct when handling the major error.
