How to Configure Jetty. Writing Java code to directly instantiate and assemble Jetty objects. This is referred to as Embedding Jetty. Using a third party IoC framework like Spring , to instantiate and assemble Jetty objects as Spring beans. Jetty Start Configuration Files. Note It is the ini files located in the Jetty base directory if different from Jetty home that are typically edited to change the configuration e. A Closer Look. Other Configuration Files. These may be standard web applications or bespoke contexts created from special purpose handlers.
To configure the default logging mechanism StdErrLog. Other logging frameworks can be utilized and also use property files for example, log4j. As a simple database for login usernames and credentials. Version: 9. Sign up or log in Sign up using Google.

Podcast Do polyglots have an edge when it comes to mastering programming Featured on Meta. It also makes it possible to split up configuration across multiple files.
Here is an example of the difference in syntax between using the Ref element, and nesting method calls. They are exactly equivalent:. An Item element defines an entry for Array and Map elements. It can be used within elements which accept values, such as Set, Put, Arg, etc. Both try to retrieve the value of jetty. If jetty. A Property element allows arbitrary properties to be retrieved by name.
It can contain a sequence of elements, such as Set, Put, Call, etc. This page was last modified , 23 April by Jesse McConnell. Back to the top. Jump to: navigation , search. Foo ; foo. Bar true ; bar. MyStuff ;. Server ; server. If not set, or set to the value of 0. The XML Property element is used to look up the host value from the jetty. The time in milliseconds that a connection can be idle before the connector takes action to close the connection. Because these values are often common to multiple connector types, the standard Jetty Server distribution creates a single HttpConfiguration in the jetty.
Virtual hosts are not configured on connectors. You must configure individual contexts with the virtual hosts to which they respond. A Jetty context is a handler that groups other handlers under a context path together with associated resources and is roughly equivalent to the standard ServletContext API.
A context may contain either standard Jetty handlers or a custom application handler. The servlet specification defines a web application. Standard web applications often need little or no additional configuration, but you can also use the techniques for arbitrary contexts to refine or modify the configuration of standard web applications.
A context may optionally have one or more virtual hosts set. Unlike the host set on a connector which selects the network interface on which to listen , a virtual host does not set any network parameters. Instead a virtual host represents an alias assigned by a name service to an IP address, which may have many aliases. To determine which virtual host a request is intended for, the HTTP client browser includes in the request the name used to look up the network address.
A context with a virtual host set only handles requests that have a matching virtual host in their request headers. A context may optionally have a classpath, so that any thread that executes a handler within the context has a thread context classloader set with the classpath.
All contexts may have additional classpath entries added. Attributes are arbitrary named objects that are associated with a context and are frequently used to pass entities between a web application and its container. For example the attribute javax. The resource base is a directory or collection of directories or URL that contains the static resources for the context.
In traditional web servers this value is often called the docroot. In an embedded server, you configure contexts by directly calling the ContextHandler API as in the following example:. The deployer discovers and hot deploys context IoC descriptors like the following which creates a context to serve the Javadoc from the Jetty distribution:.
