You need to include the portable JBoss Logging library. I know, it sounds JBoss-specific, but it's not. It's just a portable logging abstraction that we feel offers some options, such as type-safe logging messages, that you don't get w/ any other logging library (i.e., slf4j). JBoss Logging can use any popular provider that is on the classpath (log4j, slf4j, etc)


You can include this library even if you are deploying to JBoss AS. It doesn't cause conflicts.


p.s. Here is the source code for jboss-logging:

Hi All,

I am getting SEVERE: Class [ Lorg/jboss/logging/Logger; ] not found. Error while loading [ class ] when trying to include Seam Faces into my poms...

so I've downloaded the sample (seam-faces-examples-short-ly) and tried to run in... getting the same error.

I'm using NetBeans 6.9.1 and running the application from there (with GlassFish)

any ideas ?
