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 e-mail 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.
