Is there a java code where I can pass the Package name and get the implementation-version of that package from its manifest.mf file.
My requirement is that I have 5 different jar files in diffrent folders. I have to find the Implementation version from each of the jar files and diplay them as output.

I'm not sure exactly what you mean, but you could use the classes in the java.util.jar package to read the manifests of each jar.
If this is what you mean, and you need more help, then just ask again.

If you are using a recent Java version, it's much easier to use the methods on the Package class: http://java.sun.com/j2se/1.5.0/docs/api/java/lang/Package.html
