Due to lack of documentation enabling request logging for the pax-web-service OSGi bundle can be time consuming task.
This is how it can be achieved:
1. Create a OSGi fragment bundle using Maven 2 like this: pom.xml
2. Add jetty.xml to src/main/resources directory of your project. Example: jetty.xml
3. Install the bundle into your OSGI environment.
This approach works with pax-web-service-0.6.0.jar and Eclipse Equinox 3.4.0.
