Jar signer

[Eoin Mac Aoidh]

hi - Jarsigner newbie here;

Im trying to sign a Jar file, on.jar, using the Jarsigner provided by j2sdk1.4.2_04.
...so at the prompt, I type> JarSigner on.jar Eoin
Then it prompts me for the passphrase for the keystore.
I have no idea what the keystore is, or what its passphrase is for that matter! Is there a default passphrase or something?
-Actually on a broader scale - am I going about signing it correctly?

Any help greatly appreciated,
Thanks,
Eoin.

You need to use the keytool to create a keystore. Example:

keytool -genkey -keystore <name of the keystore ex:jaxb.keys> -alias <Your site url> -validity 365

Answer the questions ask.

Then, to sign your jar it's:

jarsigner -keystore <name of the keystore ex:jaxb.keys> -storepass <you would have been ask for a password, use it here> <name of jar to sign>  <Your site URL>

Hi Carl, thanks for your help, Im nearly there - there seems to be one problem though.
First I create the keystore:

 C:\HTML_TEST>keytool -genkey -keystore jaxb.keys -alias omframe.htm -validity 365   

I just copied your example "jaxb.keys" as Im not sure what this is supposed to be, but it worked fine. Then it prompted me for some indormation, which I filled in.
For the second part then, signing the Jar, the args I gave were:

  C:\HTML_TEST>jarsigner -keystore jaxb.keys -storepass abcd1234 on.jar omframe.html  

It gives the following error:

jarsigner: Certificate chain not found for: omframe.html. omframe.html must reference a valid KeyStore key entry containing a private key and corresponding public key certificate chain.

Is the problem with my url "omframe.htm"? -Thats where I want to have the jar displayed.

Sorry to bother you again.
Thanks,

Eoin.
