Previously it was not possible to select an MBean that had a path separator. This Werk implements the Jolokia path separator !/.

An example is shown in the following fragment of the jolokia.cfg file:

...
custom_vars = [('Catalina:J2EEApplication=none,J2EEServer=none,WebModule=*localhost!/docs,j2eeType=Servlet,name=default','requestCount','myspecialmetric',[],False,'number')]]
...

This will match the entry myinstance,Catalina:J2EEApplication=none,J2EEServer=none,WebModule=//localhost/docs,j2eeType=Servlet,name=defaultmyspecialmetric.requestCount0number
