Is there an analogue of OpenHab without a server with Java?
OpenHab just like the fact that adnroid/iphone client requires only specifying the server address from where to take all the render settings.
But the complexity of the hosting with Java for razorcane OpenHab server. Maybe there is something similar on the client OpenHab (with interface customization without the participation of the end user), but that the client requested data in HTTP requests.
In fact the client only visualization of current values and graphs for a specified period. Well if there are background notifications by type of push notifications. Controls (buttons/sliders, etc.) is not necessary.
OpenHAB platform intended for home installations using the most common hardware and OSes - RPi, Linux and Windowы machines. For them, the greatest Bank, there is a need of the JAVA version. If you have a problem with Java, it seems you want to do with OpenHAB something that he was not calculated.
