Jar File - Prevent Access to Source Code

Question

I want to hand over a small Java app as a runnable jar but I do not want anybody to have access to my source code. Am I right in presuming that there is no source code (.jav

Answer 1

Jar files might contain the source (you can choose whether to include it or not) so not including the source specifically isn't an issue. What you need to be aware of though is people potentially reverse engineering the class files that will be in the jar file.

You can get around this usng an obfuscator such as yGuard which easily hooks in as an ant task, but as others have said, is your code really that important that no-one else sees it?
