Hi

Can u please guide me to understand following script :

$JAVA_HOME/bin/java -cp $CLASSPATH -Djava.naming.factory.initial=weblogic.jndi.T3InitialContextFactory -Djava.naming.provider
.url=$INITIAL_CONTEXT_PROVIDER -Djava.naming.security.principal=system -Djava.naming.security.credentials=mfxclaims -Dlog.dir
=./logs -Dconfig.file=../config/batch.xml

What is the significance of following :

1. Djava
2. cp
3. Dlog
4. Dconfig

Please suggest asap

Regards
Pankaj

What you are really trying to ask perhaps is:

1. What is -D xyz=123?
2. What is -cp?

Answers:

1. The -D parameter is setting a system property for the Java session, which is why you see so many -D parameters in your command.
2. The -cp paramter is simply declaring your Class path, which is where the Java session will expect to find all of the classes used by your Java program.
