Zwave node finding nodes

Hi, i have a z-stick 2. Configured to COM port 4 in the zwave config.
Nothing is being written to the zwave log.
But in the boot log i get
"Could not load commandBuilder class: org.openremote.controller.protocol.zwave.ZWavecommandbuilder"
I had this configuration working a while ago before 2.5
Any help is appreciated, been on this all night

This error message means that the library zwave.jar is missing in the directory**/webapps/controller/WEB-INF/lib**.

This error shouldn’t happen if you use the Version 2.6.0 (Beta 1) or Version 2.5.0 of the OpenRemote controller (see : Releases).
