How to do a professional setup for java app to avoid "javaw" cannot be found?

Question

It advertises as easy install except that when I run it says cannot find javaw which spoils nearly everything.

If I were to distribute a java app myself I'd like not to have user knows anything about downloading and installing java, so any article, tool which explains how to package a java app professionally like one can do with a windows app easily ?

There are several approaches to this, all of which have their own set of drawbacks. Here are some of the most popular:

Bundle a private JRE with your application. See the README file that comes with your JRE for the details.
Use a launcher (such as launch4j) that can download a JRE at runtime if a suitable one is not found on the target machine.
Compile Java to native, then distribute as a regular Win32/Linux executable. You can do this with Excelsior JET.

Since you are concerned with deployment, you'll probably also want to create an installer for your application. There are dozens of options for this, such as NSIS.
