CLASSPATH = C:\\Program Files\\Java\\jdk1.6.0_24\\bin;C:\\Program Files\\Java\\jre6\\bin;C:\\Tomcat7\\lib\\servlet-api.jar;.

JAVA_HOME = C:\\Program Files\\Java\\jdk1.6.0_24

PATH = C:\\Program Files\\Java\\jdk1.6.0_24\\bin

TOMCAT_HOME = C:\\Tomcat7

Im really baffled as to how to proceed! Been stuck at this point!!

Answer 1

You should use ; to separate classpath entries in Windows

javac -cp .;C:\\Tomcat7\\lib\\servlet-api.jar DBConnnection.java .

but, you used a comma , . Change comma to semicolon

Note : *nix family environments use colon : to seperate classpath entries
