I am not an expert for logging but I guess that the issue is SLF4J configuration.
Instead of using logback (I have no experiences with) you can bridge SLF4J with log4j (we use it) or Java logging API (WSIT uses it) as described in https://spaces.internet2.edu/display/OpenSAML/OSTwoUsrManJavaBB.

Hi,

Thanks for the reply.
I have re-do my project after configuring Metro. However, There is a problem occurred which I guess it's related with the logging. I have added logback-core and logback-classic jars to my class path but it still doesn't work. Here is the error:

...

------------------------------------- CAUSED PROBLEM------------------------

Is there a need to use maven for building the logback?
Any help is really appreciated.

Thanks,

Rick.
