DBWS in an OSGi Environment
An Eclipselink DBWS service can be run in an OSGi environment using Javase 6's 'containerless' javax.xml.ws.Endpoint API.
Environment Setup
Download a version of the Eclipse IDE that includes the Plug-in Development Environment (PDE) (Eclipse IDE for Java EE Developers, Eclipse Classic 3.6.0 or
Eclipse for RCP and RAP Developers).
Install an OSGi-friendly JDBC driver - use Derby bundle:
- Download Apache Derby (org.apache.derby) bundle from Orbit.
- Place the org.apache.derby bundle into your $ECLIPSE_HOME/dropins folder.
- Install the EclipseLink and Jetty target Components:
Accept the license and proceed through the prompts for re-starting Eclipse ...
{NB - later, a set of updated EclipseLink bundles will be required}
Under 'Preferences' -> 'Plug-in Development' -> 'Target Platform', reload the Running Platform (Active)
Create a new Plug-in project
From the 'Plug-in Development' Perspective, create a new Plug-in project SimpleTable:
{Note the choice of 'standard' for OSGi framework}
Proceed to the next panel of the wizard where the (OSGi bundle) Activator for SimpleTable is defined:
Click 'Finish' and open the generated Activator:
<java5> package simpletable;
import org.osgi.framework.BundleActivator; import org.osgi.framework.BundleContext;
public class Activator implements BundleActivator {
private static BundleContext context;
static BundleContext getContext() { return context; }
/* * (non-Javadoc) * @see org.osgi.framework.BundleActivator#start(org.osgi.framework.BundleContext) */ public void start(BundleContext bundleContext) throws Exception { Activator.context = bundleContext; }
/* * (non-Javadoc) * @see org.osgi.framework.BundleActivator#stop(org.osgi.framework.BundleContext) */ public void stop(BundleContext bundleContext) throws Exception { Activator.context = null; } } </java5>
