OpenSAML user discussion

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:

Adding SAML token to outbound message from client

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

Thanks,

Rick.
