New cache in clustering

I have this problem:

I put in clustering plugin, in coherence-cache-config.xml this lines:

Jrdesktop distributed back-size-high 0 back-expiry 0 back-size-low 0

And I have one class using CacheFactory.createCache(“Jrdesktop”);

Why it gives me this error?

[java] java.lang.IllegalArgumentException: No scheme for cache: Jrdesktop
