Configuring Jetty JSP support in embedded mode in Maven project

I can visit .html pages with Jetty, but when I visit a .jsp page I get:

0 13:21:13 / [INFO] No JSP support. Check that JSP jars are in lib/jsp and that the JSP option has been specified to start.jar

I added the following as dependencies:

<dependency>
  <groupId>org.eclipse.jetty</groupId>
  <artifactId>jetty-webapp</artifactId>
  <version>8.0.0.M1</version>
</dependency>
<dependency>
  <groupId>javax.servlet.jsp</groupId>
  <artifactId>jsp-api</artifactId>
  <version>2.1</version>
</dependency>

Does that fulfill the "check that JSP jars are in lib/jsp" part of the error message?

Also, I have no idea what "check that the JSP option has been specified to start.jar" means in this context. I have the following:

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

    SelectChannelConnector connector = new SelectChannelConnector();
    connector.setPort(8080);
    server.addConnector(connector);

    WebAppContext webApp = new WebAppContext();
    webApp.setContextPath("/");
    webApp.setWar("src/main/webapp");
    server.setHandler(webApp);
    server.start();
    server.join();
  }

I got it to work by adding the Mortbay JSP dependency (this is in Gradle notation, but you get the idea):

compile 'org.eclipse.jetty:jetty-io:8.0.0.M3'
compile 'org.eclipse.jetty:jetty-server:8.0.0.M3'
compile 'org.eclipse.jetty:jetty-servlet:8.0.0.M3'
compile 'org.eclipse.jetty:jetty-util:8.0.0.M3'
compile 'org.eclipse.jetty:jetty-webapp:8.0.0.M3'
compile 'org.mortbay.jetty:jsp-2.1-glassfish:2.1.v20100127'

There's a larger writeup available on my blog.

I have done it without using the jars from the Jetty distribution, using only Maven dependencies:

<properties>
    <jetty.version>8.1.0.RC0</jetty.version>
    <glassfish.javax.version>2.2.3</glassfish.javax.version>
    <glassfish.javax-impl.version>2.2</glassfish.javax-impl.version>
    <glassfish.jstl.version>1.2</glassfish.jstl.version>
</properties>

<dependencies>
    <!-- Jetty Webapp-->
    <dependency>
        <groupId>org.eclipse.jetty</groupId>
        <artifactId>jetty-webapp</artifactId>
        <version>${jetty.version}</version>
    </dependency>

    <!-- JSP Support -->
    <dependency>
        <groupId>org.glassfish.web</groupId>
        <artifactId>javax.servlet.jsp</artifactId>
        <version>${glassfish.javax.version}</version>
    </dependency>

        <artifactId>jsp-impl</artifactId>
        <version>${glassfish.javax-impl.version}</version>
    </dependency>

    <!-- EL Support -->
    <dependency>
        <groupId>org.glassfish.web</groupId>
        <artifactId>javax.el</artifactId>
        <version>${glassfish.javax.version}</version>
    </dependency>

        <artifactId>el-impl</artifactId>

    </dependency>

I know this has been answered a while ago. I could not get the answer from Ben McCann to work for me. However, i had luck by adding JSP support directly to Jetty by adding

    <!--jsp support for jetty, add the 2 following -->
    <dependency>
        <groupId>org.mortbay.jetty</groupId>
        <artifactId>jsp-2.1</artifactId>
        <version>6.1.14</version>
        <type>jar</type>
    </dependency>
    <dependency>
        <groupId>org.mortbay.jetty</groupId>
        <artifactId>jsp-api-2.1</artifactId>
        <version>6.1.14</version>
        <type>jar</type>
    </dependency>

Strangely, this was not supported by the version 6.1.24 I originally had.

So in total, that made my pom.xml look like this:

http://maven.apache.org/xsd/maven-4.0.0.xsd"> 4.0.0

<groupId>wikiproject</groupId>
<artifactId>wikiproject</artifactId>
<version>1.0-SNAPSHOT</version>

<properties>
    <jetty.version>6.1.14</jetty.version>
</properties>

and my start class (which i added in folder \src\test\java\com\company\wikiproject )

package com.company.wikiproject;
import org.mortbay.jetty.Connector;
import org.mortbay.jetty.Server;
import org.mortbay.jetty.bio.SocketConnector;
import org.mortbay.jetty.webapp.WebAppContext;
/**

 */

public class Start {

public static void main(String[] args) {
    Server jettyServer = null;
    try {
        jettyServer = new Server();

        SocketConnector conn = new SocketConnector();
        conn.setPort(8080);
        jettyServer.setConnectors(new Connector[]{conn});

        WebAppContext context = new WebAppContext();
        context.setContextPath("/");
        context.setWar("src/main/webapp");

        jettyServer.setHandler(context);
        jettyServer.start();
    } catch (Exception ignore) {
        if (jettyServer != null) {
            try {
                jettyServer.stop();
            } catch (Exception e1) {
                e1.printStackTrace();
            }
        }
    }
}

}

Building upon Simon Huet's excellent answer, here's my take:

    <glassfish.javax.version>2.2.3</glassfish.javax.version>
    <glassfish.javax-jstl.version>1.2.1</glassfish.javax-jstl.version>

After reading this stackoverflow page (nice job) as well as http://wiki.eclipse.org/Jetty/Howto/Configure_JSP, I finally got this to work as well. Since my config is slightly different, I thought I'd contribute back. I have an embedded Jetty 8 installation without the 'javac' compiler, and I got it to work by using the eclipse compiler and setting the system property before creating the server, like this:

System.setProperty("org.apache.jasper.compiler.disablejsr199", "true");
Server server = new Server();

And using the following maven configuration:

<dependency>
  <groupId>org.apache.geronimo.specs</groupId>
  <artifactId>geronimo-servlet_3.0_spec</artifactId>
  <version>1.0</version>
</dependency>
<dependency>
  <groupId>org.eclipse.jetty.orbit</groupId>
  <artifactId>javax.el</artifactId>
  <version>2.2.0.v201108011116</version>
</dependency>
<dependency>
  <groupId>org.eclipse.jetty.orbit</groupId>
  <artifactId>javax.servlet.jsp</artifactId>
  <version>2.2.0.v201112011158</version>
</dependency>
<dependency>
  <groupId>org.eclipse.jetty.orbit</groupId>
  <artifactId>javax.servlet.jsp.jstl</artifactId>

</dependency>
<dependency>
  <groupId>org.eclipse.jetty.orbit</groupId>

Jetty 9.1.3, http://www.eclipse.org/jetty/documentation/current/configuring-jsp.html, and just adding jetty-jsp worked for me (plus the web.xml config from the url). No need to add jars from outside the jetty groupId (ie. mortbay).
