Unable to activate bundle in Sling that consumes SOAP service using JAX WS RI - web-services

Question

First the requirement:
I need to write code that consumes a SOAP service and build it as an OSGi bundle that can be deployed in Apache Sling. The build is done using Maven 3.0.3
What I have done so far:
I created a maven module and used this for generating SOAP client classes: https://jax-ws-commons.java.net/jaxws-maven-plugin/usage.html. I had to remove the plugin dependency jaxws-tools version 2.2.5 as it was not supporting the -encoding parameter to wsimport. Removing it automatically downloads version 2.2.8 and it works fine as it is a dependency for the POM.
Next, I changed the package type to bundle and included maven-bundle-plugin and maven-scr-plugin to package the generated code as a OSGi bundle and built it using Maven
Finally I deployed it to Sling running locally as a standalone application.
Following are the issues I faced in the given order:
javax.jws package unresolved - I included this as a private-package under configurations for the maven-bundle-plugin
Similar packages that were unresolved were added which includes:
javax.xml.ws
javax.xml.ws.handler
javax.xml.ws.spi
javax.xml.ws.spi.http
javax.xml.ws.wsaddressing
After adding these to the private-package, I started getting this error:
(javax.xml.ws.WebServiceException: Provider com.sun.xml.internal.ws.spi.ProviderImpl not found) javax.xml.ws.WebServiceException: Provider com.sun.xml.internal.ws.spi.ProviderImpl not found
Root Cause: java.lang.ClassNotFoundException: com.sun.xml.internal.ws.spi.ProviderImpl not found by org.apache.felix.http.jetty
This is where I hit a roadblock which I am not able to move past.
What I have tried so far to fix this based on numerous answers on google
tried to include this line in the sling.properties file:
sling.bootdelegation.com.sun=com.sun.*
Tried adding this line
sling.system.packages.simple=com.sun.xml.internal.ws.spi.ProviderImpl
Tried adding this line
sling.bootdelegation.class.com.sun.xml.internal.ws.spi.ProviderImpl=com.sun.xml.internal.ws.spi
Tried adding all the packages mentioned earlier to the org.osgi.framework.system.packages property as well as to the jre-1.6 property
After doing this, I can see that these packages are now being exposed by the system bundle. But only the javax.jws is showing as resolved. All other bundles still show as unresolved.
Tried all possible combinations of export-packages.
Even tried to remove unresolved packages as suggested by some posts
I am using Maven 3.0.3, JDK 1.6.0_43, Apache Sling org.apache.sling.launchpad.base.jar 2.4.0 all of which is running on my Mac Book Pro with OSX 10.8.5
