Deprecated service in wM 6.5

Hi all,

I was using a java service in WmART to create an adapter service in wM 6.1. I upgraded my IS to 6.5 and then I could not find this service in WmART. But, the fact is that the java service can still be invoked in wM 6.5 even though it is not visible in the WmART folder tree in Developer.
Does it mean that its a deprecated service in wM 6.5? Can someone throw some light on this?
