tomcat 7.0.57 startup issue

Question

I'm trying to start the tomcat from the command line on windows 7, but getting a lot of errors... I tryied to find something related but couldn't find anything similiar.

First, I downloaded apache-tomcat-7.0.57. From the command line, I set the JAVA_HOME with the path of the jdk - the version is jdk1.7.0_51. then I used the startup command.

from catalina logs:
