Apache

In the past few years many techniques have been developed to help applications interact with each other. One of them are webservice-interfaces. These interfaces are extremly popular in the world of Java software development. One Framework that can be used to build such interfaces is Apache CXF. Apache CXF delivers a toolset to develop interfaces using different protocols like XML/HTTP, RESTful HTTP, Corba and SOAP. In this article i'd like to show how easy it could be to develop a simple SOAP-webservice based on Apache CXF 2.2.6 and the Spring Framework 3.0.1. You can download the full example at the bottom of this article.

Today we're going on with the third part of our Maven 2 tutorial series. Because of the comment of Enrico I decided that this article will focus on how to configure eclipse for the usage of Maven 2 projects and how to generate the eclipse-specific files by using Maven 2. I will show these things by using the example project of part 1 and part 2 of our Maven 2 tutorial series.

Welcome back to the second part of our tutorial-series on Maven 2. This part will focus on the pom.xml and the Maven 2 dependency management, Maven properties and dependency scopes. To get started let's first set up a project similar to the project we used in the first part of this tutorial. Set up the project as described in the article Maven 2 (Part 1): Setting up a simple Apache Maven 2 Project and reopen the pom.xml.

Dependencies

Some dependencies often are needed to write your applications. Commonly we (developers, developers, developers,...) are using some open source libraries and frameworks (e.g. the spring application framework or apache commons-logging,...). Sometimes own libraries should be referenced by a java project. To solve this problem Maven delivers a very good dependency mechanism that manages the dependencies of your project transitivly.

Java software development is often associated with repetitive tasks like building project's java classes, generating documentation and reporting. Doing this repetitive tasks manually costs a lot of time and tend to be error-prone. In addition to that it is extremely boring to do the same tasks again and again. These tasks should get automated, because they are often equal. To automate these tasks a build tool that could do this work is needed. Today, many java projects are using the Maven as a build tool to manage these objectives. The Maven project reached big popularity by making repetitive tasks automatable.

Another advantage when using Maven is that all dependencies referenced by the project are resolved automatically. This is extremely helpful for bigger java projects that use a huge set of dependencies. To explain how to use Maven and to help you to get into it we start a new tutorial-series about Maven 2 at united-coders.com. The initial part of this tutorial describes how to set up a Maven 2 project structure. Further parts of this tutorial-series will describe the main functionality of Maven (e.g. plugins, archetypes, the dependency mechanism, profiles, repositories, scopes...) stepwise.

If you set up a brand new tomcat with the default configuration, you are unable to access the manager servlet. All requests on http://[YourHost]:[TomcatPort]/manager/html are responded by a HTTP Status 403 ("Access to the requested resource has been denied"). If you use your tomcat for a productive system the manager servlet should always be deactivated. The tomcat's default configuration hides the manager servlet for some security reasons. If you want to access the manager servlet you should add some lines to your tomcat-users.xml at $CATALINA_HOME/conf/tomcat-users.xml and restart your tomcat.

The default content of tomcat-users.xml is:

To make the manager servlet reachable you should modify your tomcat-users.xml like that:
