Many times we have to check what are the packages,classes included in one jar files, but due to black box(just a simple jar ) we face a trouble to check.

So with the help of following ways you can check it.

jar tf <PATH_TO_JAR

But if you are looking for a specific class or package then you can use following command.

jar tf <PATH_TO_JAR> | grep -i <PARTIAL_NAME_OF_CLASS>
