using Eclipse for Android development - cant find jarsigner.exe4

Now I am at the stage of preparing my android app for publishing I discover that jarsigner.exe is not on my hard disk ( done a full search) I have the jave sdk and java jre and keytool.exe but no jarsigner. I have googled and followed thro links that appeared to offer download of jarsigner but none of them acftually do. I have been to the official java site but cant find an option to download this file - can anyone help?

I am using Eclipse and thought that when I did the various downloads for Eclipse, Android and Java I would have all the necessary files.

From the reading I have done it seems 开发者_JAVA技巧that the Eclipse export wizard only prepares debug signed .apk and I must follow the unsgned/keytool/jarsigner route to get a distrbutable file.

You don't need it.

Right-click on the project in the Package Explorer view, in the popup menu choose Android Tools/Export signed application package.

In the directory of the JDK (not JRE).

%JDK_HOME%\bin\jarsigner.exe

You can download it from here - http://www.oracle.com/technetwork/java/javase/downloads/index.html
