Adding to the classpath on OSX

Question

Can anyone tell me how to add to the classpath on OSX?

Answer 1

You can set it in /etc/profile. Open terminal, "sudo vim /etc/profile" and add the following line:

setenv CLASSPATH (insert your classpath here)

Answer 2

Normally there's no need for that. Fist of all

echo $CLASSPASS

If there's something in there you probably want to check Applications -> Utilites -> Java.

Answer 3

If you want to make a certain set of JAR files (or .class files) available to every Java application on the machine, then your best bet is to add those files to /Library/Java/Extensions.

Or, if you want to do it for every Java application, but only when your Mac OS X account runs them, then use ~/Library/Java/Extensions instead.

EDIT: If you want to do this only for a particular application, as Thorbjørn asked, then you will need to tell us more about how the application is packaged.
