Running Jetty 7 server in eclipse? - eclipse

Question

I'm trying to set up Eclipse to run and deploy my projects to a Jetty 7 server (the oldest version available from http://download.eclipse.org/jetty/). I've downloaded Jetty 7 and unpacked it, and I've installed the Jetty plugin from the available server adapters list, but when I try to configure a new Jetty server, the server type list only contains "Jetty 6". If I use this and point it at my server runtime, when I try to start it I get the following error:
java.lang.NoClassDefFoundError: org/mortbay/start/Main
Caused by: java.lang.ClassNotFoundException: org.mortbay.start.Main
at java.net.URLClassLoader$1.run(Unknown Source)

at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)
at java.lang.ClassLoader.loadClassInternal(Unknown Source)
Exception in thread "main"
I'm guessing I need a different adaptor to start Jetty 7, but I have no idea where to find it.

Answer 1

Better than using the WTP adapters I prefer to use an embedded jetty.
I just create a regular java project, let's call "embedded-jetty". I make the original webapp project a requirement to this project in the Projects section of the
Java Build Path of the project properties. Than I create a class that start a jetty instance like this:
import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.webapp.WebAppContext;
public class JettyServer {
public static void main(String[] args) {
Server server = new Server(8080);
WebAppContext context = new WebAppContext();
context.setResourceBase("../webapp-project/WebContent");
context.setDescriptor("../webapp-project/WebContent/WEB-INF/web.xml");
context.setContextPath("/");
context.setParentLoaderPriority(true);
server.setHandler(context);
try {
server.start();
server.join();
} catch (Exception e) {
e.printStackTrace();
}
}
}
On the embedded-jetty project I create a "lib" folder and copy all the libs from the jetty/lib folder, then I add the libs on the Libraries of the project properties.
Running and debugging the jetty embedded works great for me, the jsp and class reloading works like a charm

Answer 2

There's a new (official!) Jetty WTP Plugin supporting Jetty 7.x and 8.x: http://wiki.eclipse.org/Jetty_WTP_Plugin

Answer 3

The problem is that the package name changed with the migration to Eclipse, and the Jetty folks are still busy.
Your easiest option is to download Jetty 6 from Codehaus (http://dist.codehaus.org/jetty/), unpack it somewhere and use the Jetty 6 adapter.

Answer 4

Run-Jetty-Run Eclipse plug-in have well support for both Jetty7 and Jetty 8 ,
and easier to use then WTP Eclipse for me .
It's worth to try it. :)

You can use the Jetty Maven Plugin to configure jetty server in your eclipse very easily. Include the following elements in you pom.xml
<jetty.version>9.3.0.M1</jetty.version>
<!-- JETTY DEPENDENCIES -->
<dependency>
<groupId>org.eclipse.jetty</groupId>
<artifactId>jetty-server</artifactId>
<version>${jetty.version}</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.eclipse.jetty</groupId>
<artifactId>jetty-servlet</artifactId>
<version>${jetty.version}</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.eclipse.jetty</groupId>
<artifactId>jetty-webapp</artifactId>
<version>${jetty.version}</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.eclipse.jetty</groupId>
<artifactId>jetty-servlets</artifactId>
<version>${jetty.version}</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.eclipse.jetty</groupId>
<artifactId>jetty-ant</artifactId>
<version>${jetty.version}</version>
</dependency>
and in your pom's plugins managements,
<plugin>
<groupId>org.eclipse.jetty</groupId>
<artifactId>jetty-maven-plugin</artifactId>
<version>${jetty.version}</version>
<configuration>
<stopKey>keyStop</stopKey>
<stopPort>8181</stopPort>
<httpConnector>
<host>0.0.0.0</host> //also localhost or IP address
<port>8080</port>
</httpConnector>
</configuration>
</plugin>
Or you could separate out the server configuration in separate jetty-.xml files. See Configuring the jetty container for more.
Now right click your maven project and run the goal,
mvn jetty:run
to start the server on default port 8080. And to stop the server,
mvn jetty:stop
If not specified, Jetty will create a ServerConnector instance
listening on port 8080. You can change this default port number by
using the system property jetty.http.port on the command line, for
example, mvn -Djetty.http.port=9999 jetty:run.
Note that since jetty-9.0 it is no longer possible to configure a
https connector directly in the pom.xml: you need to use jetty xml
config files to do it.
