Hi,
I was finally able to get this to work. Here are the things I had
to do.
1) I upgraded OSGi from 3.4 version to 3.6, just in case that was the problem.
2) I had missed including jetty-servlets jar in the list of bundles, so
included that jar
3) Started a small webapp, as mentioned above. Did not run into issues. Was
able to set defaultDescriptor as null
4) Later used WebAppProvider class, but this kept failing with this problem
(http://stackoverflow.com/questions/29274336/getting-java-lang-classnotfoundexception-org-eclipse-jetty-servlet-listener-int)
java.lang.ClassNotFoundException:
org.eclipse.jetty.servlet.listener.IntrospectorCleanerIn order to resolve this,
had to alter the jetty-webapp manifest to import org.jetty.servlet.listener
package.Now the webapps are correctly getting deployed for me. I also had to
specify a proper defaultDescriptor for it to work when using WebAppProvider
Also another problem I found was that the server does not now work with my
legacy web applications, as the DTD for web.xml appears to be differentMy
web.xml had <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web
Application 2.3//EN" "http://java.sun.com/j2ee/dtds/web-app_2_3.dtd";>, and
this was causing errorosgi> 2015-08-17

So overall was able to get things to work, but looks like I will have to make
a lot of changes here and there :(.Thanks for all the help.Thanks,

There are people on this forum that work on the jetty-osgi layers, stick
around, they'll show up.
You might have more luck using those layers vs making your own bundle.
I just can't help you, as I avoid OSGi with a 100km pole.
But I know that the jetty-osgi layers represent at least 1,000 man hours of
effort between all of the jetty and osgi experts that commit to it.

Well, that's really too bad, considering this was working well in Jetty 6. Is
there any other forum where I can get some help.? Is there anyone else on this
list who has done similar thing.?
Thanks for your help anyway.

Oh crap, i didn't notice you were using OSGi, sorry.
Configurations under the OSGi environment cannot be made that simply, sorry.
Disregard everything i said.
I have no advice for you under OSGi.

Hi Joakim,
Thank you for your answer. However unfortunately, it is not helping.
I made the changes you suggested, so effectively my code now, is
Server server = new Server(port);
WebAppContext webapp = new WebAppContext();
webapp.setContextPath("/");
webapp.setExtractWAR(true);
webapp.setWar("E:\\jettyTest\\webapps\\testWebApp.war");
server.setHandler(webapp);
server.start();
But even with this change, I am seeing that the exception still is, as follows

I have not tried moving to that version yet. Shall try that and update, But I
am wondering if there is something more to this that I am missing. I did try
placing the webdefault.xml that came along with the distribution, in the path
it is looking for, but then that failed with some parsing exception.
Thanks,
Srijith.

Server server = new Server(80);
ServletContextHandler context = new
ServletContextHandler(ServletContextHandler.SESSIONS);
context.setContextPath("/");
context.addServlet(new ServletHolder(new HelloServlet()),"/hello");
ContextHandlerCollection contexts = new ContextHandlerCollection();
WebAppContext webapp = new WebAppContext();
webapp.setResourceBase(".");
Don't use this with a webapp (the .setWar() a few lines below this does this
for you, and correctly)
webapp.setDescriptor("WEB-INF/web.xml");
webapp.setContextPath("/");
This is the same contextPath as your ServletContextHandler above, this will
never work, as your ServletContextHandler will answer all requests, never
letting your WebAppContext process anything.
Just skip the ServletContextHandler entirely.
Use webapp.addServlet() instead.
webapp.setExtractWAR(true);
webapp.setWar("E:\\jettyTest\\webapps\\testWebApp.war");
contexts.setHandlers(new Handler[]{context, webapp});
If you have no ServletContextHandler, then you don't need the
ContextHandlerCollection.
server.setHandler(contexts);
If you have no ContextHandlerCollection, you can just use
server.setHandler(webapp)
server.start();
The server starts up fine, the servlet handler is also registered fine, but my
webapp Context startup always fails with the following exception

The change to not use .setResourceBase() should have made an improvement here.
