Re-Sign a Content Archive

If the certificate you used to sign a content archive has expired, you can re-sign the content archive using a new certificate. The example in this section assumes that the JAR signing tool, content archive to re-sign, and keystore are located on the same system.

1. On the system, open a command prompt and create a directory in which to extract the files from the content archive and go to that directory. For example, run the following commands:

   Windows:

   mkdir C:\tmp\contentarchive
cd C:\tmp\contentarchive

   Linux:

   mkdir /tmp/contentarchive
cd /tmp/contentarchive

2. Extract the files from the content archive. For example, run the following command:

   Windows:

   "C:\Program Files\Java\jdk\bin\jar" -xvf C:\tmp\SERVICE_OFFERING_2c9f4ab8b896014ac3520ca7016d.zip

   Linux:

   /usr/bin/javac/bin/jar -xvf /tmp/SERVICE_OFFERING_2c9f4ab8b896014ac3520ca7016d.zip

3. Remove the expired signature files. For example, run the following command:

   Windows:

   rmdir /q /s META-INF 

   Linux:

   rm -rf META-INF

4. Create a new content archive.

   Windows:

   "C:\Program Files\Java\jdk\bin\jar" -cvf C:\tmp\SERVICE_OFFERING_2c9f4ab8b896014ac3520ca7016d_NEW.zip *

   Linux:

   /usr/bin/javac/bin/jar -cvf /tmp/SERVICE_OFFERING_2c9f4ab8b896014ac3520ca7016d_NEW.zip *

5. Change to the JDK's bin directory. For example, go to:

   Windows:

   C:\Program Files\Java\jdk\bin

   Linux:

   /usr/bin/javac/bin

6. If you have access to the keystore, remove the expired certificate by running the following command:

   Windows:

   keytool -delete -keystore C:\tmp\.keystore_archive_signing -alias csa_archive
-storepass <keystore_password>

   Linux:

   keytool -delete -keystore /tmp/.keystore_archive_signing -alias csa_archive
-storepass <keystore_password>

7. If you are using a certificate generated for you, get the keystore, keystore password, and alias to access the certificate. If you are using a self-signed certificate, follow the instructions in Locating or Creating a Keystore and Certificate to generate a new self-signed certificate.
8. Re-sign the content archive. Follow the instructions in Signing the Content Archive to re-sign the content archive (use the new content archive name, SERVICE_OFFERING_2c9f4ab8b896014ac3520ca7016d_NEW.zip).
