[slf4j-user] blog entry on JCL

[Matt Raible]

Is the solution to replace all my application's org.apache.commons
imports with slf4j imports?  Is so, I can do that.  However, will the
other libraries (i.e. Spring and Hibernate) continue to have this
missing location issue when I try to turn up the logging on them?

Thanks,

Matt
