I am a noob trying to learn about using OSGi and Jetty (and eclipse IDE). So I was running through this tutorial at http://wiki.eclipse.org/Jetty/Tutorial/Jetty-OSGi_SDK and I got down to the part titled "Create a first web-bundle ". When I try running the configuration it says:
...
22:02:30.739 [Framework Event Dispatcher] DEBUG org.eclipse.jetty.util.log - loaded class org.eclipse.jetty.webapp.WebAppContext from org.eclipse.osgi.internal.baseadaptor.DefaultClassLoader@aa37a6

...
When I look at the source code for line 561 of org.eclipse.jetty.webapp.WebInfConfiguration, it says:
Connector[] connectors = context.getServer().getConnectors();
I followed the tutorial instructions precisely. I am about to do it all again on another machine to verify. But I would appreciate any help in resolving what is going wrong.
I was wondering once I get it working in eclipse IDE, is there any way to just push an button and have it output a standalone app? Be nice if the tutorial showed how to do that.
Thanks for listening. I can post more debug output if needed. Doesn't seem to be any errors or warning mentioned above that, and there are quite a few lines of output.
