You have to usr (configure later) option for all Produscts.
then you will see config files for each product which you need to edit manulay before starting the configuration.
the conf files will have all information, like username passwords, port, etc.
check JES instalation manual
JES Windows installer has 2 configuration options
- auto configure - this is meant for single system evaluation configuration, the only question asked is admin user/pwd
- config later - you get to configure all ports/params
looks like you selected #1 . the ports are defaulted in this option (say 80 for webserver) but if the port is otherwise busy and cannot be assigned to JES products, it uses internal logic t assign port numbers.
if you need control over ports and all other config params, please use config later option. This is documented in install guide
