so it's been 4 days now that Tomcat won't launch for some reason, tried everything i could but Nothing really worked for me, one of the errors i'm getting is as mentionned in the title, but i'm have a lot more than those (here is the full error log Apache TomCat failed to start lifecycle exception)
So first i thought i didn't have the class ServiceRegistry but i do have it As you can see here
UPDATE
So i added hibernate core into the lib folder Under apache tomcat installation and the server started again, but it's not mapping my servlets for some reason
**UPDATE 2 **
I copied ojdbc6.jar and hibernate -core into the lib folder of tomcat and now it works fine
Thanks for your help lads.
