RAP/Running RAP on virgo
Work in Progress...
@see Blog post Running RAP on Virgo
You used to have just two options for deploying a <a href="http://eclipse.org/rap/">RAP</a> application:
- Packing your application into a WAR archive and deploying it on a standard servlet container such as Tomcat, or
- Embedding the Application and a servlet container in a standalone Equinox instance.
Now you have a third option because RAP runs on <a href="http://eclipse.org/virgo/">Virgo</a>! Virgo is a full-featured OSGi based application server and is one of the shining new stars of the Eclipse ecosystem. Previously, we weren't able to deploy RAP applications on this server because we were blocked by bugs relating to split packages. However, over the last few weeks we worked together with the Virgo team to fix these issues and we are happy to report success.
Here are the steps we used to deploy RAP on Virgo. We know the process can be improved, but just to give you an idea of how it works, try the following:
- Download the latest Virgo Kernel (RC1)[1] and unpack the downloaded archive to a directory (We'll use ${KERNEL_HOME} in this post).
- Download the latest RAP Runtime[2] and extract the contents of the plugin folder into the Virgo repository:
unzip rap-runtime-1.3.1-R-20100915-2301.zip "eclipse/plugins/*.jar" -x "eclipse/plugins/*.source_*" -d /tmp cp /tmp/eclipse/plugins/*.jar ${KERNEL_HOME}/repository/usr
- (via OSGi console) Enable the OSGi console by configuring the User Region, Virgo's subsystem for managing user applications.
Open $KERNEL_HOME/config/org.eclipse.virgo.kernel.userregion.properties and uncomment the osgi.console property:
... # osgi console support osgi.console=2401
- (optional) Change the default port of the OSGi HttpService
export JAVA_OPTS=-Dorg.osgi.service.http.port=10081</li>
./startup.sh
...

- Virgo Plans[3] encapsulate the artifacts of an application as a single unit. We've created a rap-demo.plan for you. You can inspect and download from here:
