Java: how do I check if a node (javax.jcr.node) property exists?

I just want to find out if a node property exists.

I was looking at the API reference guide

• Node (Content Repository for Java Technology API Version 2.0) (click here)
• Property (Content Repository for Java Technology API Version 2.0) (click here)

and nothing there stands out.

Thanks
