Hi Martin,

Thanks for your response.
The only errors I see in the logs are below at the startup:

INFO: JSR 356 WebSocket (Java WebSocket 1.0) support is not available when running on Java 6. To suppress this message, run Tomcat on Java 7, remove the WebSocket JARs from $CATALINA_HOME/lib or add the WebSocket JARs to the tomcat.util.scan.DefaultJarScanner.jarsToSkip property in $CATALINA_BASE/conf/catalina.properties. Note that the deprecated Tomcat 7 WebSocket API will be available.

I am not sure if this would help. Regarding the screenshot, how can I upload a png attachment? The comment section is only allowing me to add .txt files.

martin_grofcik

Change extension to txt ….
or share image through some another server.

Hi,

I already asked Tijs and Joram for support. I was not able to get UI running too. If you are interested we can create crystaball jUnit test to demonstrate the functionality.
