my directory structure

So can anyone suggest me how to make .exe or a executable jar file that can be run directly?

thanks in advance..

This problem is really not fixed by 'making an exe'. I highly recommend removing all reference to the Windows specific native. — Andrew Thompson, Sep 05 '12 at 05:07
@Chris That is not really a duplicate, once we sort out the "don't need an EXE" matter. — Andrew Thompson, Sep 05 '12 at 05:10

In Eclipse, you can export your project into an executable JAR file by right-clicking on your source folder, selecting "Export...", selecting "Java->Executable JAR File". Eclipse will then offer the option to either extract your external JAR dependencies into the final jar file, or place them into a folder with the final jar's manifest classpath referencing them.

*"either extract your external JAR dependencies into the final jar file, or place them into a folder with the final jar's manifest classpath referencing them."* The latter is much more versatile. It allows easy reuse of common APIs, amongst other benefits. – Andrew Thompson Sep 05 '12 at 05:09

The MANIFEST.MF file in your jar should specify the Main-Class and the classpath. Something like this:

Main-Class: full.package.path.to.your.main.class
Class-Path: space separated list of jar files

You would probably want to use an automatic build tool like Ant, Maven or Gradle in order to generate the MANIFEST.MF file in your jar that way.

Use Launch4J for wrapping jars in Windows executables.
