Embedding Jetty
Quick Start
Quick Start - Handlers
The following code implements an anonymous hello handler and starts a jetty server with it:
Quick Start - Servlets
Here is a simple example of embedding Jetty using a Hello world servlet:
Setting up the classpath
To run Jetty you need only the following jars on the classpath:
- servlet-api-2.5-6.x.jar
- jetty-util-6.x.jar
- jetty-6.x.jar
This gives you the capability to handle HTTP with handlers, servlets and webapplications.
Additional features such as JSP and AJP require additional jars (normally found in subdirectories of $JETTY_HOME/lib).
Java Server Pages
JSP2.1
| Remember! 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:
- ant-1.6.5.jar
- core-3.1.1.jar
- jsp-2.1.jar
- jsp-api-2.1.jar
JSP2.0
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
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
- commons-el-1.0.jar
- jcl104-over-slf4j-1.0-rc5.jar
- slf4j-simple-1.0-rc5.jar
- xmlParserAPIs-2.6.2.jar
- xercesImpl-2.6.2.jar
More Examples
These examples are all included as part of the standard Jetty distribution in the $JETTY_HOME/examples/embedded sub project.
- FileServer - simple HTTP file server
- http://jetty.mortbay.org/xref/org/mortbay/jetty/example/OneHandler.html - Embed a single handler - useful when there is only a single simple source of content.
- http://jetty.mortbay.org/xref/org/mortbay/jetty/example/ManyHandlers.html - Embed multiple handlers, one called after the other on each request.
- http://jetty.mortbay.org/xref/org/mortbay/jetty/example/OneContext.html - An example of a handler within a context, which allows a contextPath, resourceBase and class loader to be set.
