Not able to Print logs using SLF4j from Idp

[Surinaidu Majji]

Thank you for your reply Cantor,

If you want to get logging via log4j to work, you drop in a shim that
implements log4j on top of slf4j, which is available from the slf4j project.

-->Initially, I thought that the Shibboleth idp is using Slf4j(I did not
observe log4j-over-slf4j), So i can implement calls of slf4j using log4j to
print the logs in my module.

I went through the links that you have shared with me, i understood the
what is log4j-over-slf4j. But I could not confirm that how to print the
logs in my external module which i have kept as a jar in the
"idp/Web-inf/libs". Please help me to make it work.

Since we are using "ExternalAuthn", We have our servlets to handler the
log-in mechanism, So i made this servlet as a jar file and kep it in
the   "idp/Web-inf/libs"
in tomcat web project.
