Problem when starting my Tekkit 2.1.1 server :( Any help most appreciated!

Question

Hello. I want to create a tekkit server for my friends to play on, so I downloaded the server 2.1.1 software from the website, extracted the files, and put my hamachi ipv4 address into the server.properties file. However, when I try to launch the server, this message appears:

I am new to running servers, and cannot work out how to fix the problem. Any help would be most appreciated! :) Thank you in advance.

I had this problem as well what you need to do is download a java file, the one you need is java 1.7.0_04 make this your used java and everything should work!
