The recommendation on this issue is to contact the certificate vendor and follow their installation instructions as they should work correctly.
If following vendor instructions still does not work, try the following:
Reinstall the certificate into the CACERT bundle,
Import Root certificate and public root certificate into the Java Store directory:
Note: This is just an example, your directory structure can be different.
Drive X:\Program Files\Java\jdk1.5.0_11\jre\lib\security\cacerts
