[rules-users] Test if String endsWith()

[Omar Baqueiro]

It seems I have to use 5.0.I am using Drools as part of a third party
framework called MuleESB (
http://www.mulesoft.org/documentation/display/MULE3USER/Drools+Module+Reference
), so I don't think I have to use the provided version.

Is the str[endsWith] operator available on this 5.0 version?

Otherwise, it seems I'll have to do create my own like:

Thanks a lot.
