Question : Keystore file to sign jar via a thawte code signing certificate

We are using two applets in our application that are being compiled using a keystore file. The following are the relevant lines from our build.xml file for ant:

 <signjar jar="${build.lib.dir}/rtb-admin.jar" alias="swb_thawte" storepass="MX37SF1K" keystore="cert/swb_thawte.ks"/>
        <signjar jar="${build.lib.dir}/rtb-bidder-signed.jar" alias="swb_thawte" storepass="MX37SF1K" keystore="cert/swb_thawte.ks"/>

The certificate is now expiring and we need to compile the application with the new one.

We got a certificate from thawte after creating a csr and it begins with this line:
-----BEGIN PKCS #7 SIGNED DATA-----

Now I am unsure as to how to proceed. I see there is an old file "thawte_certificate.txt" in the certificates directory which looks like the one thawte just sent me, so i need to replace that one, but I don't know how to generate the file swb_thawte.ks which is being used inside the buld.xml file.

You need to embed Thawte certificate in your certificate store and then replace the new file.
