Introduction

Jetty can deploy web applications as war files (packed or unpacked), as provided or with overridden configuration, with static or hot deployment.


Steps

Webapps Deployment

The $JETTY_HOME/webapps directory is scanned at startup for webapplications to deploy:

  • The file foo.war will be deployed as a webapp at context /foo
  • The directory foo/ will be deployed at context /foo. If the directory has a WEB-INF subdirectory, it will be treated as servlet webapp, otherwise it will served only as static content.
  • If both a foo.war and a foo/ directory exists, then the one with the most recent last-modified date is used.
  • If the webapp is called root.war or the directory is called root/ then it will be deployed at the / context.

Webapp deployment was controlled the WebAppDeployer class. From 7.0.2 onwards this has been replaced by the WebAppProvider of the DeploymentManager.

See also older (but mostly relevant) Jetty-6 WebAppDeployer documentation.

Contexts Deployment

The $JETTY_HOME/contexts directory is scanned at runtime for context.xml files, that describe either:

  • a standard war file (or directory), plus additional configuration.
  • a custom jetty context.

Webapp deployment was controlled the ContextDeployer class. From 7.0.2 onwards this has been replaced by the ContextProvider of the DeploymentManager.

See also older (but mostly relevant) Jetty-6 ContextDeployer documentation.

Jetty Maven Plugin

If you develop your web application as a maven project, then it can be deployed in jetty with "mvn jetty:run" using the Jetty Maven Plugin
