We are happy to announce that the first release of a set of maven archetypes is out!!! The goal of this set is to provide project templates that can fulfill various development needs. You can find the JCG roadmap at the end if this post.
This first release aims to provide a project template – architecture for web applications. The name of the archetype is jcg-andygene-archetype and it is hosted at the following location: http://code.google.com/p/jcg-andygene-web/
The license for this set of archetypes is Apache License. Developers are free to change it.
Spring MVC: Spring’s Web MVC framework is designed around a DispatcherServlet that dispatches requests to handlers, with configurable handler mappings, view resolution, locale and theme resolution as well as support for upload files.
Spring Security: Spring Security is a powerful and highly customizable authentication and access-control framework. It is the de-facto standard for securing Spring-based applications
JasperReports: Powerful reporting tool. It can generate reports in a various set of formats.
Drools: Powerful business logic platform . Drools use Rete algorithm for decisions and can be dynamically be configured to change business logic of your application.
Activiti: Powerful bpmn2 implementation that users can use as a link between business people and developers.
CXF: Web Services stack.
ActiveMQ: JMS implementation .The Java Message Service (JMS) API is a Message Oriented Midleware (MOM) API for sending messages between two or more clients.
Ehcache:Second level cache that can boost your application.
Hibernate JPA2: Implementation of JPA2 Specification. An Object Relational Map.
- Apache Maven 2
- Tomcat 6
- (Optional) A development toolset (e.g. Eclipse or SpringSourceTool Suite or any other toolset. For conveniency it would be desirable to support maven integration) for viewing the created project architecture and for developing based on this archetype.
Download the archetype. Extract it somewhere in your disk and type the following in the root folder of the archetype:
Generating Your First Project
To generate you first project type the following in your workspace directory:
mvn archetype:generate -DarchetypeCatalog=local -DarchetypeGroupId=com.javacodegeeks -DarchetypeArtifactId=jcg-andygene-web-archetype
You will be prompted for several parameters of the archetype. An example is the following:
Define value for property 'groupId': : com.javacodegeeks Define value for property 'artifactId': : MyFirstJCGProject Define value for property 'version': 1.0-SNAPSHOT: 1.0.0.Final Define value for property 'package': com.javacodegeeks: com.javacodegeeks [INFO] Using property: activemqpersistencedir = ~/activemq [INFO] Using property: activemqpersistencesize = 32mb [INFO] Using property: activemqsessioncachesize = 100 Define value for property 'activitipassword': : nothing [INFO] Using property: activitiurl = jdbc\:h2\:mem/activiti [INFO] Using property: activitiusername = sa Define value for property 'databasepassword': : nothing [INFO] Using property: databaseurl = jdbc\:h2\:mem/andygene [INFO] Using property: databaseusername = sa [INFO] Using property: db = h2 [INFO] Using property: tomcathost = localhost:8080 Confirm properties configuration: groupId: com.javacodegeeks artifactId: MyFirstJCGProject version: 1.0.0.Final package: com.javacodegeeks activemqpersistencedir: ~/activemq activemqpersistencesize: 32mb activemqsessioncachesize: 100 activitipassword: nothing activitiurl: jdbc\:h2\:mem/activiti activitiusername: sa databasepassword: nothing databaseurl: jdbc\:h2\:mem/andygene databaseusername: sa db: h2 tomcathost: localhost:8080
This will generate a maven project with name MyFirstJCGProject (Depending on the parameter you provided before)
Below the structure of the main elements of this project is presented:
- dao: It contains the Data Access Objects (DAOs)
- domain: It contains the Data Transfer Objects (DTOs)
- drools: It contains the drool object used.
- jms: It contains the JMS listener and sender.
- service and service/impl: It contains the main services.
- util: It contains various utilities (e.g. validation)
- web: It contains the controllers.
- webservices: It contains the soap interfaces.
- activiti: It contains the flows.
- drools: It contains the rules.
- META-INF: It contains the persistence.xml.
- META-INF/spring: It contains properties files and application context for spring relates sources.
- java: It contains the unit tests.
- Resources: It contains log4j.
Under src/main/webapp (files for the we application):
- /WEB-INF/spring: It contains the spring descriptor for web application.
- /WEB-INF/layouts: It contains the web templates.
- /WEB-INF/reports: It contains the jasper reports.
- /WEB-INF/classes: It contains the web properties.
- /WEB-INF/views: It contains the structure of the web pages.
Running/building Your First Project
To run – build your project, type the following (if your development toolkit has maven integration you can perform the following action from inside your toolkit):
cd MyFirstJCGProject mvn install
A war file will be generated at target/MyFirstJCGProject.war . Copy this file at TOMCAT_HOME/webapps.
Start Tomcat and point the browser at the following location http://tomcathost/MyFirstJCGProject
You must edit catalina.sh, for mac or linux ,or catalina.bat, if you are running on windows, located at TOMCAT_HOME/bin and add the following lines:
JAVA_OPTS="-Djava.awt.headless=true -Dfile.encoding=UTF-8 -server -Xms1536m -Xmx1536m -XX:NewSize=256m -XX:MaxNewSize=256m -XX:PermSize=256m -XX:MaxPermSize=256m -XX:+DisableExplicitGC"
Notice: Drools require connection to the internet .If you want to run your project without having access to the internet copy MyFirstJCGProject/src/main/resources/META-INF/spring/drools-spring-1.0.0.xsd to a location to your drive and edit MyFirstJCGProject/src/main/resources/META-INF/spring/applicationContext-drools.xml : Change http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-container/drools-spring/src/main/resources/org/drools/container/spring/drools-spring-1.0.0.xsd to file:///path/to/drools-spring-1.0.0.xsd.
Archetype Supported Databases:
- H2(default) db property value [h2]
- Postgres db property value [postgres]
- Mysql db property value [mysql]
- Oracle db property value [oracle]
Notice: Case you choose oracle you must download oracle, oracle driver and install it to your repository.
