Version 1.2 of StarXpert:Save zimlet did not work ok with our Zimbra 7.2 test version.
This is what we had to do in order to make it work:
instead of the first lib symbolic link which complained about the already existant link.
ln -s /opt/zimbra/jetty/webapps/zimbra/WEB-INF/lib/zimbrasoap.jar \
ln -s /opt/zimbra/jetty/webapps/zimbra/WEB-INF/lib/zimbrastore.jar \
ln -s /opt/zimbra/jetty/webapps/zimbra/WEB-INF/lib/zimbrataglib.jar \
It would be nice to add this information to the zimlet docs. It seems that some zimlets such as anymeeting, asterisk, sugar make use of the lib directory.
