Environment variables for java installation

Question

How to set the environment variables for Java in Windows (the classpath)?

Answer 1

For deployment better to set up classpath exactly and keep environment clear. Or at *.bat (the same for linux, but with correct variables symbols):

CLASSPATH="c:\lib;d:\temp\test.jar;"
CLASSPATH=%CLASSPATH%;"

Or at command line or *.bat (for *.sh too) if classpath id not very long:

java -cp "c:\lib;d:\temp\test.jar;"
