Have you set the CLASSPATH variable? I see in your post you have mentioned "CLASS PATH" just checking its one word CLASSPATH, no spaces in between

for windows you can set classpath by following command

set CLASSPATH=C:\lucene-2.4.1\lucene-core-2.4.1.jar


Another observation, not sure why you need ANT here if you are doing javac on command line. But if you need it you ANT_HOME needs to be set like this

set ANT_HOME=C:\apache-ant-1.7.1
set PATH=%ANT_HOME%\bin



The value in your post - ANT_HOME=C:\apache-ant-1.7.1;%ANT_HOME%\bin
is not correct.
