How to Install Jetty Application Server

via How to Install Jetty Application Server | Examples Java Code Geeks.

Jetty is an open-source Servlet container and Application Server which is known to be lightweight, portable, robust, flexible, extensible and providing support for various technologies like SPDY, WebSocket, OSGi, JMX, JNDI, and JAAS. Jetty is very convenient for development and also widely used in production environments.

In this post, we are going to detail how to install and configure a Jetty Server. We are first going to describe how to setup and run a standalone Jetty. Thereafter we will mention some configuration options and skim through the modular architecture of Jetty.

Jetty presents Standalone, Embedded and Jetty Maven Plugin modes of operation. In this post we are going to use standalone Jetty.

Jetty JNDI Example

via Jetty JNDI Example | Examples Java Code Geeks.

The Java Naming and Directory Interface (JNDI) is a Java API for a directory service that allows Java clients to discover and lookup data and objects via name. Data sources, Mail Servers or Messaging queues are among the common objects that can be discovered through JNDI. JNDI lookup strategy abstracts applications from the external resources and makes them more configurable.

In this example, we are going to enable Jetty for JNDI lookups. As in the previous examples, we will start with embedded Jetty and programmatically enable JNDI lookups. We will register a JDBC datasource and demonstrate how we can lookup and access this datasource through JNDI. Thereafter we will see how JNDI resources can be configured in a Standalone Jetty.

Jetty JSP Example

via Jetty JSP Example | Examples Java Code Geeks.

JSP (JavaServer Pages) which is core part of Java EE, enables developers to create dynamic web content based on the Java Servlet technology. In this example, we are going to enable Jetty for JSP. We will start with Embedded mode of Jetty. We are going to initialize our embedded Jetty to run JSP pages. Thereafter we will continue with standalone mode and shortly mention the JSP configuration in standalone mode.

Jetty supports two JSP Engine implementations: Apache Jasper and Glassfish Jasper. Starting from Jetty version 9.2, the default and favored implementation is Apache Jasper. In this example we are going to use this one; however we will show how we can switch to Glassfish implementation in the standalone mode.

At this point, we have to mention that, this example should not be considered as a JSP tutorial but a demonstration of JSP on Jetty container.

How to create a Web Application Project with Java/Maven/Jetty or Tomcat

via How to create a Web Application Project with Java/Maven/Jetty | Guru.

In this article, we create a simple web application with the Maven Archetype plugin. We’ll run this web application in a Servlet container named Jetty, add some dependencies, write simple Servlets, and generate a WAR file. At the end of this article, you will also be able to deploy the service in Tomcat.

System requirements

Jetty JMX Example

via Jetty JMX Example | Examples Java Code Geeks.

JMX technology provides a simple, standard way of managing resources such as applications, devices, and services. Jetty itself does not provide a GUI based console for management/monitoring, however ii presents a solid integration with JMX, which enables us to monitor/manage Servers through JMX.

In this post we are going to discuss JMX integration of Jetty. We will start with an Embedded Jetty example. We will first configure our embedded server to be accessible through JMX; thereafter we are going to incorporate Managed Objects in Jetty style. After the embedded example, we are going to show how we can enable JMX in a standalone Jetty Server. During the example, we are going to monitor and administer our Jetty through JConsole.

In Jetty, the main constructs such as handlers and holders are also JMX beans. This makes almost every single piece of Jetty observable or controllable through JMX. In addition this, Jetty enables creation of JMX objects(MBeans) through annotations(which is an extension to standard MBean capabilities).

Jetty Authentication Configuration Example

via Jetty Authentication Configuration Example | Examples Java Code Geeks.

Jetty provides support for standard authentication methods BASIC, DIGEST, FORM and CLIENT-CERT as well as other pluggable mechanisms like JASPI and SPNEGO. Jetty also offers a set of built-in Login Service alternatives for authenticating the user along with extension capabilities.

In this example we will configure authentication in Jetty. Among the various alternatives, we have chosen BASIC authentication for this example with HashLoginService. We are going to start with an Embedded Jetty; we will configure BASIC authentication with a security realm and login service programmatically.

We will also demonstrate different access rights for different role types. In the last part of our example, we are going to apply same configuration on a standalone Jetty server.

Jetty OSGi Example

via Jetty OSGi Example | Examples Java Code Geeks.

The OSGi specification defines a modularization and component model for Java applications. Jetty leverages OSGi support providing an infrastructure that enables developers to deploy Jetty and web applications inside an OSGi container. One can deploy traditional Java Web Applications or Context Handlers on Jetty within the OSGi container; in addition to this, OSGi bundles can be deployed as web applications.

In this example, we are going to show how we can deploy Web Applications on Jetty within an OSGi container. We are going to enable a Jetty Server on an OSGi container first, thereafter we are going to deploy a Servlet on our OSGi powered Jetty.
