I'm trying another way to try and get spring mvc with an embedded jetty instance. I found this example on github (https://github.com/s4nchez/jetty-spring-mvc-jar/blob/master/src/main/java/com/sandbox/Sandbox.java) , but it is using an older version of jetty (6.1.9) while I am using 7.6.2.v20120308.

So I used the same code snippet:

final Server server = new Server(8080);

final ContextHandler contextHandler = new ContextHandler();

contextHandler.setContextPath("/");

server.setHandler(contextHandler);

final DispatcherServlet dispatcherServlet = new DispatcherServlet();

dispatcherServlet.setContextConfigLocation("classpath:web-context.xml");

final ServletHandler servletHandler = new ServletHandler();

servletHandler.addServletWithMapping(new ServletHolder(dispatcherServlet), "/*");

contextHandler.setHandler(servletHandler);

server.start();

server.join();

*** The github code uses import org.mortbay.jetty.handler.ContextHandler; while I am using: import org.eclipse.jetty.server.handler.ContextHandler;

Everything compiles fine, but this is the issue it seems?? (see error output below)

It also uses this in the pom.xml (com.my.path.to.main was changed to the actual one)

<artifactId>maven-shade-plugin</artifactId>

</plugin>

When I run java -jar myjar.jar I get this error:
