Cannot run simple servlet on GlassFish-4

My simple REST based webservice does encounter a problem when I try do run it. It seems that the deployment succeeds, but when I access the servlet I get this error: 

WARNING:   StandardWrapperValve[MySimpleServer]: Servlet.service() for servlet MySimpleServer threw exception
    java.lang.AbstractMethodError: javax.ws.rs.core.UriBuilder.uri(Ljava/lang/String;)Ljavax/ws/rs/core/UriBuilder;
        at javax.ws.rs.core.UriBuilder.fromUri(UriBuilder.java:119)
        at com.sun.jersey.spi.container.servlet.ServletContainer.service(ServletContainer.java:662)
        at javax.servlet.http.HttpServlet.service(HttpServlet.java:790)

My root pom.xml is very simple and just contains these dependencies and plugins:

<dependencies>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.8.2</version>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>javax</groupId>
            <artifactId>javaee-web-api</artifactId>
            <version>6.0</version>
            <scope>provided</scope>
        </dependency>
        <dependency>
            <groupId>com.sun.jersey</groupId>
            <artifactId>jersey-server</artifactId>
            <version>1.8</version>
        </dependency>
    </dependencies>
    <build>
        <finalName>MySimpleServer</finalName>
        <plugins>
            <plugin>
                <artifactId>maven-compiler-plugin</artifactId>
                <configuration>
                    <source>1.7</source>
                    <target>1.7</target>
                </configuration>
                <version>3.1</version>
            </plugin>
        </plugins>
    </build>

The web.xml:

<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
    version="3.0">
    <servlet>
        <servlet-name>MySimpleServer</servlet-name>
        <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>MySimpleServer</servlet-name>
        <url-pattern>/*</url-pattern>
    </servlet-mapping>
</web-app>

Actually, it worked earlier today and I have not made any changes at all to the pom.xml file. Is it something with Glassfish4 server? I have made a clean build, redeployed the servlet, restarted GlassFish etc. Nothing helps.

I've had this problem when I've accidentally mixed Jersey / JAX-RS versions - IE having both Jersey 1 & 2 libs on the classpath.

I can't see how this happens with just the three dependencies in your pom, but I'm quite sure this is happening somewhere.

Looking at your stacktrace, I can see this is what's happening.

This is javax.ws.rs-api/2.0 UriBuilder.java

118   public static UriBuilder fromUri(String uriTemplate) {
119        return newInstance().uri(uriTemplate);
120   }

Which is exactly what you're getting - a call to UriBuilder.uri(String) on line 119.

Looking at the equivalent line numbers in the UriBuilder source from Jersey 1.8 and it's a Javadoc comment for a different method.

So, you've somehow got jax-rs 2 on your classpath and it's causing this problem.

Maybe you have it on a shared / common classloader, or a stray lib lying around.

UPDATE

Yes - glassfish ships with Jersey / JAX-RS libs. See this question

As an aside - if you're able, I'd upgrade to Jersey 2. Hope this helps
