Quick Guide to Embedding Jetty


For a more detailed look at embedding Jetty in your application, see the Tutorials on Embedding Jetty.

Setting up the classpath

To run Jetty, you need only these jars:

  • jetty.jar
  • servlet-api-2.5.jar
  • jetty-util.jar

Those jars give you the ability to serve web applications.

If you wish to use JSPs, then you will need a couple of additional jars.


JSP 2.0 is used with version 2.4 of the servlet specification. Depending on the functionality you require, you may be able to use this version rather than the newer JSP2.1 jars.

Code Block

These are the dependencies when JSP 2.0 is used:
* ant-1.6.4.jar
* jasper-compiler-5.5.15.jar
* jasper-runtime-5.5.15.jar
* jsp-api-2.0.jar
* xercesImpl-2.6.2.jar
* commons-el-1.0.jar
* jasper-compiler-jdt-5.5.15.jar
* jcl104-over-slf4j-1.0-rc5.jar
* slf4j-simple-1.0-rc5.jar
* xmlParserAPIs-2.6.2.jar



You need to use J2SE5 (aka jdk 1.5) if you wish to use JSP2.1.

This is the jsp version mandated by servlet specification 2.5. You will need these jars:

Code Block

* ant-1.6.5.jar  
* core-3.1.1.jar  
* jsp-2.1.jar  
* jsp-api-2.1.jar


The jetty configuration files (eg jetty.xml) have an xml syntax that is a straightforward mapping of the java API. Take a look at the files in etc/ for some hints on what calls to make in your own code. Here's the minimal code to set up a Jetty server and webapp:

Code Block

org.mortbay.jetty.Server server = new Server();
org.mortbay.jetty.nio.SelectChannelConnector connector = new SelectChannelConnector();
server.setConnectors (new Connector[]{connector});
WebAppContext wah = new WebAppContext();
