KB (V)PRO/5 Rev 22+ fails to start

(V)PRO/5 Rev 22+ fails to find the certificate.bls

This occurs when BLS versions of (V)PRO/5 start in directory is not the same directory where the certificate.bls resides, which is the same directory where the (V)PRO/5 executable resides. (V)PRO/5 22+ uses standard file search processes to find the certificate.bls and the blsclient.conf.

To fix this issue, please add the following properties to the config.bbx the application uses:

CERTIFICATE=
BLSCLIENT=

Provide the full path and filename to these files.
For example: 

CERTIFICATE=/path/to/PRO5/certificate.bls
BLSCLIENT=/path/to/PRO5/blsclient.conf

Also, adding the directory (V)PRO/5 directory to the PREFIX in the config.bbx is an option.

PREFIX /path/to/PRO5/

The error messages about not ‘finding’ these files are not always clear or indicative of the actual problem.

The blsclient.conf is where you configure the (V)PRO/5 client to find the BLS if it is running on a remote machine.  The default configuration looks for the BLS running on the local machine.  Modify this as needed if your BLS is running on a remote machine, change this localhost reference in the blsclient.conf to the name/ip of the machine running the BLS:

servers=localhost
