As I've said several times, you need to update any scripts I've posted to the latest version. The error you reported indicates you're using an out-of-date script.
does it mean that i have to remove the pmsencoder 1.1.0.jar as well? because in the location where you mentioned that is 1.2.1 version i cant find pmsencoder 1.2.1.jar it's only pmsencoder.groovy. and what is the WEB.jar for?
