Hi Ivan,
I think you will have to ask SAG to give you the project (Eclipse project) that contains the java files, properties files and the Ant build scripts.
Then you can change the labels as you like.
After you build the project you will get some files in he form:
wm-mws-library_es-mx.jar ;wm-directory_es-mx.jar ;wm-calendar_es-mx.jar ;wm-caf-server_es-mx.jar ;wm-caf-jsf-mws_es-mx.jar...
.
The obtained jar and war files will have to be deployed to MWS and to "common\lib".
For wM version 7.x this steps are described on the SAG site (see link from previous comment). For wM 8.x I could not find them.
br,
Vlad
