how to change portletID

Hello,

i have to build a portal based on pluto. But I have a problem with the
portletID.
The portletID usually contains context path, portlet name and meta info.
(Created in java class PortletWindowConfig in package
org.apache.pluto.driver.services.portal in pluto-portal-driver). I only
need the portlet name in my portlets. So I changed the java code from
"return contextPath + "." + portletName + "!" + metaInfo;" to "return
portletName;". Then installed pluto on apache tomcat with command "mvn
pluto:install -DinstallDir="path to tomcat"". But I still have the old
portletID in my html source code. Have somebody any solution for my
problem?

Thanks,
Serge
