This question comes up often enough, so I created an example project of using Embedded Jetty with JSP enabled.

https://github.com/jetty-project/embedded-jetty-jsp/

Load up this project into your favorite IDE.

Run the org.eclipse.jetty.demo.Main class and then use your browser and open http://localhost:8080/

Quick Tour

src/main/java/org/eclipse/jetty/demo/Main.java contains the part that creates / configures / and starts the embedded server.

Pay particular attention to:

• The JspServlet must be named "jsp" - see jspServletHolder()
• The org.eclipse.jetty.containerInitializers needs to be setup for the JSP initializers
• The ServletContainerInitializersStarter bean needs to be added
• The InstanceManager reference needs to be added
• A proper javax.servlet.context.tempdir needs to be created
• Set org.apache.jasper.compiler.disablejsr199 to false to use the standard JavaC compiler
• The Classloader for the Context must not be a System Classloader. - see getUrlClassLoader()
• The DefaultServlet must be named "default" - see defaultServletHolder()

src/main/java/com/acme/DateServlet.java is an example of how to forward to a JSP from a Servlet.

The DateServlet is mapped to path spec of /date/ in Main.java

So once you hit http://localhost:8080/date/ the request will hit the servlet, which in turn forwards to to /test/tag2.jsp
