Here is the steps :
1. Make sure that you have an SDK 1.4.2 keytool and jarsigner in your path. These tools are located in the SDK bin directory.

2. Create a new key in a new keystore as follows:

keytool -genkey -keystore myKeystore -alias myself

You will get prompted for a information about the new key, such as password, name, etc. This will create the myKeystore file on disk.

3. Then create a self-signed test certificate as follows:

keytool -selfcert -alias myself -keystore myKeystore

This will prompt for the password. Generating the certificate may take a few minutes.

4. Check to make sure that everything is okay. To list the contents of the keystore, use this command:

keytool -list -keystore myKeystore

It should list something like:

Keystore type: jks
Keystore provider: SUN

Your keystore contains 1 entry:

myself, Tue Jan 23 19:29:32 PST 2001, keyEntry,
Certificate fingerprint (MD5):
C2:E9:BF:F9:D3:DF:4C:8F:3C:5F:22:9E:AF:0B:42:9D

5. Finally, sign the JAR file with the test certificate as follows:

jarsigner -keystore myKeystore test.jar myself

Repeat this step with all of your JAR files.
