A jar file is just a compressed version of the class files in form that java
can handle directly. I'm surprised that your app server can't use a .jar

But... if you really need to, extracting the class files is easy enough-
just use "jar xf <filename>" for example: "jar xf jdbc7.1-1.2.jar"

make sure the files go in the appropriate subdirectory of your classes
directory since they are part of a package.

the command "java -version" should tell you what you have.

You should be able to work with any version. Assuming you are running v7.1
of PostgreSQL, if you have Java1.2 or above, use jdbc7.1-1.2.jar, otherwise,
use jdbc7.1-1.1.jar

It sounds like you're new to this. I've compiled a FAQ based on common
questions from new folk. It might be helpful to you:
