To complete the installation, run the ikeyman tool:
# ./ikeyman.sh
In the ikeyman interface, select your key database file again and enter the keystore's password. Select "Personal Certificates" from the drop-down box and choose "Receive". Select "Base64-encoded ASCII data" in the "Data Type" list.
Take the file ending in .cer from the email that was sent when your certificate was issued and place it on the WebSphere server. Click "Browse" and locate the certificate that you just copied. Create a label for the certificate and click "OK". Your new certificate should be displayed within the keystore.
