EJB + JPA + JSF + JAX-RS Page edited by Yegor Bugayenko Comment: more about rempl.com Changes (15) h1. RESTful Web Service, a Business Case h1. Business Case The example explains how a real-life business problem could be solved using OpenEJB in a combination with other open-source frameworks and tools. The example covers the entire software development lifecycle, starting from problem analysis, architecture, design, build automation, unit testing, implementation, and deployment. We have to create a web service that stores text documents online. By means of stateless HTTP requests our customers will be able to create, read, update, and delete (CRUD) plain text files. The product is hosted at [http://oss.rempl.com] and its source code is available at [http://svn.rempl.com/trunk/rempl/rempl-oss]. The purpose of this system is to collect UML meta information from open source products. The information collected has to become visible for end-users in form of diagrams and texts. h1. Architecture and Design TBD... The following components are used in the system: h1. Build automation * OpenEJB as an implementation of EJB * OpenJPA, an implementation of JPA * Jersey, implementation of JAX-RS * Mojarra, implementation of Java Server Faces (JSF) TBD... There are a number of service layers in the system: !http://www.rempl.com/rempl-oss/tikz/architecture-components.png! h1. Unit tests h1. {color:#000000}Presentation Layer includes JSF (Mojarra), JAX-RS (Jersey), and JEE container (Tomcat). In other words, everything on top of "{color}{color:#000000}[Delegates|http://www.rempl.com/rempl-oss/apidocs/com/rempl/oss/delegates/package-summary.html]{color}{color:#000000}" in the diagram. More about {color} TBD... Business Layer includes EJB (OpenEJB), Brokers (Stateless Session Beans), and JPA entities. {color:#000000}Persistence Layer includes JPA (OpenJPA), JDBC (MySQL JDBC Driver) and the MySQL server.{color} h1. Build Automation and Tests Build automation is managed by [Maven 3|http://maven.apache.org/ref/3.0/], see our [pom.xml|http://trac.fazend.com/rempl/browser/rempl/trunk/rempl/rempl-oss/pom.xml]. There are four levels of testing in the product: # Static analysis # Out-of-container unit testing # In-container functional testing # On-location testing During static analysis we are using [Checkstyle|http://maven.apache.org/plugins/maven-checkstyle-plugin/], [PMD|http://maven.apache.org/plugins/maven-pmd-plugin/], [FindBugs|http://mojo.codehaus.org/findbugs-maven-plugin/], [Cobertura|http://mojo.codehaus.org/cobertura-maven-plugin/], [maven-dependency-plugin|http://maven.apache.org/plugins/maven-dependency-plugin/analyze-only-mojo.html], [xml-maven-plugin|http://mojo.codehaus.org/xml-maven-plugin/]. Important to note that all these tools are used as gate condition checkers, not as post-factum analyzers.  Out-of-container tests are automated with JUnit. Good example of a Stateless Session Bean out-of-container testing: [UserMgrBeanTest.java|http://trac.fazend.com/rempl/browser/rempl/trunk/rempl/rempl-oss/src/test/java/com/rempl/oss/brokers/UserMgrBeanTest.java]. In-containter functional testing is automated with JSFUnit and embedded Tomcat container. _more later..._ _On-location testing is not yet automated... working on it..._ h1.

There are four levels of testing in the product: Static analysis Out-of-container unit testing In-container functional testing On-location testing During static analysis we are using Checkstyle, PMD, FindBugs, Cobertura, maven-dependency-plugin, xml-maven-plugin. Important to note that all these tools are used as gate condition checkers, not as post-factum analyzers.  Out-of-container tests are automated with JUnit.
