In this example, "Application requires feature jaxws which is not supported by Liberty Runtime" is displayed when attempting to run an application on WebSphere Liberty in Eclipse.
Used the productInfo featureInfo command to determine if jax-ws is installed in Liberty.
~]# liberty_home/bin/productInfo featureInfo
If jax-ws is not listed, install jax-ws.
~]# liberty_home/bin/installUtility install jaxws-2.2
