PATH - CLASSPATH

The name itself indicated the functionality...

CLASS-PATH : It contains the paths of class files which are stored

Ex: CLASSPATH="C:\Program Files\Java\jdk1.7.0_51\jre\lib\rt.jar"

PATH : It contains the path for the executables

Ex: PATH="C:\Windows\System32\notepad.exe"

PATH is the OS related..It contains executable file information like bin etc..

CLASSPATH is also related to OS only but it contains information like ZIP, JAR file..

PATH=$PATH: <JDK bin path> 

CLASSPATH=$CLASSPATH: <WL-Home\server\lib>

Set PATH as follows:

$export PATH=$PATH:/usr/java/jdk1.5.0_07/bin

To check the path Env variable(view the contents of PATH):

$ echo $PATH

WL_HOME/server/bin/setWLSEnv.sh (on UNIX)

PATH=$PATH: <JDK bin path>

CLASSPATH=$CLASSPATH: <WL-Home\server\lib>
