To use SSL certificate with Java you can install it directly in you application server or install in in web server that acts as proxy to your application server. In the latter case you will also need dedicated IP addon to be able to use default HTTPS port 443. We will happily help you with these setups - just open a ticket.
You may provide your own CSR (Certificate Signing Request) or we will generate one for you.
We preinstall JDK, chosen application server (Tomcat, Glassfish, etc.) and any additional software (SQL server, mail server, etc.) on request. Please contact our Support or enter your software requirements in order notes.
