Jetty/HowTo/Using Jetty with Eclipse
You can use Jetty in a variety of ways when developing in Eclipse.
WTP Style Use
A problematic mechanism is the WTP style approach to webapp development. Under certain circumstances this works for certain people and if it does, great, enjoy. Here is a link to a Jetty WTP Plugin that Angelo Zerr contributed.
The embedded approach is an often used mechanism for developing in Eclipse. This strategy involves writing a small main method that starts Jetty and deploys your servlets programmatically. You can control the starting and stopping of your webapp through normal runtime measures.
Run-jetty-run is a plugin that allows you to easily make run-configurations where Jetty starts a webapp. You point the run configuration to your webapp-directory, configure the context path and port, and you're pretty much done. Works for jetty 6, 7 and 8 - a version of each is included.
You can use Jetty with JUnit or the like, where in @Before and @After there is a starting and stopping of a Jetty server. This is a popular approach to developing in Eclipse, and one that we employ heavily. If you're interested in this approach, look through the unit tests for things like jetty-server and jetty-client for a wealth of examples. Also see the embedded-examples project for a number of simple examples in common usage scenarios.
