I am having a terrible time getting Linux 64bit/zwave/DSC combination to work with Openremote. I installed Ubuntu 14.04 64 bit server and my DSC alarm setup sent smooth. I then spent a long time trying to figure out how to get my Z-Stick to work and eventually replaced my txrxSerial, sorry I can't remember the file right now, with the 64 bit version and my z-wave started and created the zwave.log file. The problem is my DSC alarm no longer works unless I go back to the 32 bit txrx file. Is this just a reality for Openremote and 64 bit? Will I really need to install older 32 bit tech to make this work?

I can just say that I have RXTXcomm-2.2-pre2.jar on the classpath. I have also installed the librxtx-java package in Ubuntu, from the 64-bit repositories. The current version is 2.2pre2-11. This works with Ubuntu 14.04 and 14.10. In the transition to 64-bit I sometimes were out-of luck with the rxtx that came with Ubuntu. I then resolved the issue by downloading and installing my own rxtx. You will find posts on this forum about that.

Note that rxtx needs a java API, that is the jarfile. It also needs a dynamic library, for Linux this is The dynamic library need to match your architecture, 32-bit or 64-bit.
