GeoTrust will email you your certificate. If the certificate is an attachment (Cert.cer), you can use the file. If the certificate is in the body of the email, copy and paste it into a text file (such as OriginalCert.txt) using Vi or Notepad. Do not use Microsoft Word or other word processing programs that may add characters. Confirm that there are no extra lines or spaces in the file.
To import the SSL Certificate run the following command:
C:\bea\jdk\bin\keytool -import -alias <your_alias_name> -keystore <your_keystore_filename> -file <your_certificate_filename>
