Question

I am attempting to add BASIC authentication to a RESTful web service that I have created using Jersey/JAX-RS and Tomcat Apache 7.0. In the future I want to deploy this web service on WebSphere so I have chosen to use Spring Security (ver 2.5.6) for my project.

My problem is this: though I believe my various xml files are correct and I have added spring.jar to my classpath I am getting the following error when starting the server.

SEVERE: Error configuring application listener of class
org.springframework.web.context.ContextLoaderListener java.lang.NoClassDefFoundError: javax/servlet/ServletContextListener
at java.lang.ClassLoader.defineClass1(Native Method)
at java.lang.ClassLoader.defineClassCond(Unknown Source)
    ...

and so on. Every resource that I have looked at states that I should add spring.jar to my class path, which I have. I am completely new to Spring so if any of my files are setup incorrectly please tell me. Here are all of the relevant XML files and settings.

security-applicationContext.xml:

<?xml version="1.0" encoding="UTF-8"?>

This looks like a similar problem.

You might want to try different Tomcat versions.

You are missing dependencies.

Minimal spring-security dependencies should be:

<properties>
    <spring.version>3.0.1.RELEASE</spring.version>
</properties>
<dependency>
    <groupId>org.springframework.security</groupId>
     <artifactId>spring-security-web</artifactId>
     <version>${spring.version}</version>
</dependency>
<dependency>
     <groupId>org.springframework.security</groupId>
     <artifactId>spring-security-config</artifactId>
     <version>${spring.version}</version>
</dependency>
<dependency>
     <groupId>org.springframework.security</groupId>
     <artifactId>spring-security-taglibs</artifactId>
     <version>${spring.version}</version>
</dependency>
<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-core</artifactId>
    <version>${spring.version}</version>
</dependency>

You don’t seem to be using maven so this site will help you find the jars you need. Just search for the <artifactId> and you will be able to download the .jar for the dependency.

This HOWTO might help you on a minimal spring-security configuration.
