How to Unjar a JAR file without JDK and without winzip/winrar ??

Hi All,

For one of business scenario, I want to un Jar a JAR file.
The challenge here is it should happen without using JDK.
Also, the unjar should happen without winzip/winrar.
I only have JRE installed on that system (windows).

Is there any way, I can do it.
Its a client requirement & I am stuck into how to do this ??

Need help from you guys...

Thanks in advance...

Check out JarInputStream and/or JarFile

You have a client that wants to unzip a jar but doesn't want to install any software to unzip a jar?

You have a dumb client. Why do they want to unzip a jar anyway?

Thanks Maneesh.

It seems that ths might solve the problem.
However, as we want the solution urgently, if possible, can you provide me some examples on the same.

I tried googling out, but couldnt get much good help..

I would really appreciate if you coudl provide me some examples on the same.

If they have no means of unzipping a jar then they have no means of unzipping a jar.

Are you really sure that you have got the requirement right? I have known of atleast one customer who had a similar (but not the same) requirement. They did not want to use Winzip or Winrar (some security issues) but they were ready to use a different approved product to unjar it. Have you asked your customer why they want to avoid those existing tools? That will help you understand their requirements better.
