[slf4j-user] How to use slf4j to consolidate JUL and log4j output?

[Rishi Madan]

Hi , Using

 SLF4JBridgeHandler.removeHandlersForRootLogger();


 SLF4JBridgeHandler.install();
will remove Resource Bundle messages for JUL logging when used with
Application Servers like WebSphere etc. This may cause missing of
server admin messages like , Server open for e-business.

However in new versions of WebSphere , fix for Resource bundle lookup is added.
