I have a jersey REST endpoint exposed via an HttpServer created using
com.sun.jersey.api.container.grizzly2.GrizzlyServerFactory from jersey
1.10 (with dependency org.glassfish.grizzly 2.1.2).
The endpoint is packaged within a swing app and serves as a callback
endpoint for a pubusbhubbub subscriber. This endpoint is called by the
pubsubhubbub server to verify a subscribe request. The point of all this
is to keep the swing client synchronized with events that transpire in
my server in an event-driven manner.
All is well when the pubsubhubbub server call the jersey endpoint in my
swing app when the swing app is run as a standalone java app.
However, if I run the swing app via jnlp using java webstart I am
getting the following exception. It seems this likely is due to some
class loader issue and version mistmatch. Can any one guide me as to how
to diagnose this further?
