How to use Phone gap with SUP Hybrid application?

Hello,

I searched on net to use or call phone gap APIs from my HWC workflow application(no native please). Did not get any suitable tutorial.

I'm going through this:

But, it seems that, these are kind of Native(java and Objective-c)...

Actually, I want to call phone gap API/functionality from JS(that are available in generated workflow in sybase unwired workspace 2.1.3).

Could any one please guide me with a step by step approach?

Thanks.
