The Tomcat Maven Plugin not only allows us to deploy our mavenized application to an existing Tomcat server but also to run our web application with an embedded instance from our project’s directory. Recently I needed to add basic authentication to such an instance and wanted to share the steps necessary here Prerequisites We just need Maven and a JDK … Java Development Kit >= 6 Maven 3 Project Setup I am using the webapp archetype here We’re adding the following configuration for the Tomcat plugin to your pom.xml – my final descriptor is this one pom.xml...

In today’s Android tutorial we’re going to take a look at Android’s Widget API and how to make a widget interact with a service using intents. Figure 1. hasCode Android Widget Tutorial Logo We’re going to create a fully functional application that allows us to enable or disable our smartphone’s screen lock settings using a widget that can be placed on our home screen. Finally, I am going to show how to use a smartphone to test and debug our application and connect it to the IDE. ...

Today we’re going to take a look at the Maven Embedded GlassFish Plugin and how it allows us quick creation of GlassFish server instances in no time and Java EE 6 application deployment. Figure 1. GlassFish + Maven With a few lines of configuration in your Maven’s pom.xml we’ve got a running GlassFish instance and are able to redeploy our application fast by pressing enter in our console. In the following tutorial we’re going to build a Java EE 6 Web Application with a stateless session bean and a web servlet and finally deploy – and redeploy the application using the Maven GlassFish Plugin. ...

Today we’re going to take a look at two specific frameworks that enables you to efficiently test your REST-ful services: On the one side there is the framework REST-assured that offers a nice DSL-like syntax to create well readable tests – on the other side there is the Jersey-Test-Framework that offers a nice execution environment and is built upon the JAX-RS reference implementation, Jersey. In the following tutorial we’re going to create a simple REST service first and then implement integration tests for this service using both frameworks. ...

Sometimes in a developer’s life there is no clean API available to gather information from a web application .. no SOAP, no XML-RPC and no REST .. just a website hiding the information we’re looking for somewhere in its DOM hierarchy – so the only solution is screenscraping. Screenscraping always leaves me with a bad feeling – but luckily there is a tool that makes this job at least a bit easier for a developer .. jsoup to the rescue! ...

Using the contract-first approach to define a web service offers some advantages in contrast to the code-first approach. In the following tutorial we’re going to take a look at some details of this approach and we’re going to implement a real SOAP service using JAX-WS, Maven and the Eclipse IDE. Finally we’re going to run our service implementation on an embedded Jetty instance and we’re going to take a look at soapUI and how to test our service using this neat tool. ...

Aspect oriented programming and the definition of cross-cutting-concerns is made easy in Java EE 6 using interceptors. In the following tutorial we’re going to take a look at the different possibilities to apply interceptors to your EJBs at class or method level and how to setup a GlassFish instance to run the examples. Prerequisites We don’t need much for the following tutorial – just a JDK, Maven and GlassFish… Java Development Kit 6 GlassFish 3.1 Maven 3 ...

Portlets are a common technology to create plug&play components for modern web applications and are specified by the Java Community Process in several specification requests. In the following tutorial we’re going to learn how to create custom portlets and how to deploy and embed them in Liferay, the popular open-source enterprise portal. In addition we’re taking a look at inter-portlet-communication and how to create portlets using annotations. Finally we’re building a portlet-state-aware Java-Server-Faces portlet using the jsf-portlet-bridge mechanism. ...

Often ant tasks are used in Maven builds but wouldn’t it be more attractive to integrate the Groovy language into our build process? GMaven is the answers to this problem and brings together Maven and Groovy. It allows us to execute Groovy scripts inline from our Maven configuration, from a local script or even from a remote location. In the following short examples I am going to show how to configure Maven to execute Groovy scripts from different locations. ...
