Spring application with embedded application cannot find webdefault.xml when starting from jar

I have a spring application that uses an embedded instance of Jetty.

project
   | src
      | controller
      | webapps
          | jsp
          | WEB-INF
              | web.xml
              | applicationContext.xml
              | spring-servlet.xml

my jar has the same tree structure, but I keep getting

    d:\test>java -jar springtest.jar
2011-11-22 15:37:02.576:INFO::jetty-7.x.y-SNAPSHOT

I have the following java class that starts a mooring server instance

String webDir = this.getClass().getClassLoader().getResource("webapps").toExternalForm();
Server server = new Server(8080);

WebAppContext context = new WebAppContext();
context.setContextPath("/");
context.setResourceBase(webDir);
context.setParentLoaderPriority(true);
HandlerList handlers = new HandlerList();
handlers.setHandlers(new Handler[] { context, new DefaultHandler() });
server.setHandler(context);
server.start();

my web.xml looks like

<welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/applicationContext.xml</param-value>
    </context-param>

    <listener>
        <listener-class>
            org.springframework.web.context.ContextLoaderListener
        </listener-class>
    </listener>

    <servlet>
        <servlet-name>spring</servlet-name>
            <servlet-class>
                org.springframework.web.servlet.DispatcherServlet
            </servlet-class>
        <load-on-startup>2</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>spring</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

This application works fine if I run inside the IDE, but it does not work with JAR. How can I solve this problem to have a single jar file in which there is a web application?

I had a similar problem, and I solve it with this main implementation of the class:

private static final int PORT = 8080;
private static final String WAR_LOCATION = "src/webapps"; //in your case I guess
private static final String CONTEXT_PATH = "/movence"; //change it if you want

public static void main(String[] args) throws Exception {
    Server server = new Server();
    WebAppContext context = new WebAppContext();
    SocketConnector connector = new SocketConnector();

    setupConnector(connector);
    setupContext(server, context);
    setupServer(server, context, connector);
    startServer(server);
}

private static void startServer(Server server) throws Exception, InterruptedException {
    server.start();
    server.join();
}

private static void setupServer(Server server, WebAppContext context, SocketConnector connector) {
    server.setConnectors(new Connector[] { connector });
    server.addHandler(context);
}

private static void setupConnector(SocketConnector connector) {
    connector.setPort(PORT);
}

private static void setupContext(Server server, WebAppContext context) {
    context.setServer(server);
    context.setContextPath(CONTEXT_PATH);
    context.setWar(WAR_LOCATION);
}

Missing your webdefault.xml(Jetty):

java.io.FileNotFoundException: d: \ test \ org \ eclipse \ jetty \ webapp \ webdefault.xml

see What is webdefault.xml?

If you have a custom location, you need to add it:

context.setDefaultsDescriptor("/my/path/to/webdefault.xml");
