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. ...

I’ve released a new plugin for the popular Confluence Wiki that extends the user profile with new tab that displays the user’s vcard as a QR code. This allows an easy import of address data from Confluence to your smartphone. Features Display of a Confluence user’s contact data as a QR code in a separate tab in the user profile More to be implemented .. Installation Just download the plugin from Atlassian’s Plugin Exchange and install it using the Universal Plugin Manager in your Confluence’s administration area That’s all .. nothing to configure here .. ...

I am currently working on a plugin that needs to receive some information from an LDAP/Active Directory using JNDI. That’s why I needed to set up a directory server in a short time and I didn’t want to waste much effort for here. Luckily for me the Apache Directory Studio saved my day and allowed me to set up everything I needed in a few minutes. Short and sweet: In this tutorial I’m going to show you how to configure everything you need in your Eclipse IDE and finally how to query the created LDAP server with a tiny java client using JNDI. ...

Message Driven Beans are no new concept due to the fact that they exist since EJB 2.0 but in Java EE 6 and the EJB 3.0 specification it is even more fun to use them. In this tutorial we’re going to take a look at the specification and create an example application that transfers some objects via the Java Message Service to a Message-Driven Bean deployed on a GlassFish application server. ...

Behaviour Driven Development is the keyword when we’re talking about test scenarios written in an ubiquitous language, strong interaction with stakeholders, product owners or testers and well described, common understandable test scenarios. The popular JBehave framework is our tool of choice here and allows us to decouple our test stories from the test classes, offers an integration for web tests using Selenium and finally there’s a helpful Maven plugin for JBehave, too. ...
