~~Title: VisionX Logging ~~

VisionX starts an embedded application server ([[http://tomcat.apache.org/|Tomcat]]) and an embedded database ([[https://www.postgresql.org/|PostgreSQL]]). Especially log output from the application server is interesting. If you use logging in your application in the live preview, you won't see the message without enabling VisionX logging.

It's simple to enable logging. Open the file **logging.properties** from //lib// directory. Add following line at the end:

<code properties>
com.sibvisions.visionx.DesktopLauncher.level = ALL
</code>
This line will enable logging to console and file. If you want to see log messages immediately, be sure that you start VisionX with e.g. visionx.bat. The console window will show log messages.
