How to globally catch all exceptions?

[membersound]

Hi,

how could one best catch all exceptions within the application that occur and are not handled anywhere?
Would it just require a try-catch block in the onModuleLoad()? Or maybe an extra Servlet?

Thanks

Use the GWT.setUncaughtExceptionHandler() [1].

Where can I find the logfile on the serverside if using the standard gwt.logging.simpleRemoteHandler?

I see the console output in eclipse, but need this in some file.
com.google.gwt.logging.server.RemoteLoggingServiceUtil logOnServer [...]

This is standard java.util.logging configuration: http://docs.oracle.com/javase/6/docs/technotes/guides/logging/overview.html#1.8

(and it'll depend on your servlet container, e.g. http://tomcat.apache.org/tomcat-7.0-doc/logging.html#Using_java.util.logging_(default) )

I recently implemented this and found this article particularly useful:
