To simplify the development of Web projects on Apache Karaf/Apache ServiceMix, we have created archetypes
to setup WAR or WAB projects. They are very basic but they can be
enriched with framework like Struts 2, Wicket, plain JSP or MyFaces JSF
as they are currently supported on Apache Karaf - ServiceMix.
For the GWT users, it exists now an archetype which will create a GWT project. To create such a project, you must generate a project from the archetype
mvn archetype:generate \ -DarchetypeGroupId=org.ops4j.pax.web.archetypes\ -DarchetypeArtifactId=wab-gwt-archetype \ -DarchetypeVersion=2.0.0-SNAPSHOT \ -DgroupId=com.mycompany \ -DartifactId=hello \ -Dversion=1.0
build next the WAB using hello/mvn clean install
and deploy it on Apache Karaf
Verify that the web site is well registered :
Next, you can navigate to your application in your browser and click on the button to say Hello.
Remark : A WAB project is nothing more than a WAR excepted it is packaged as a bundle file, that we have removed the WEB-INF/lib dependencies and create a MANIFEST file containing the OSGI instructions.
