On the configuration of a new server in JAVA

Hello,

As the picture shows,I really do not know what should fill in a red circle.I first encountered this situation.Can anyone tell me?

Thanks

Unless you know of any tweaks to use, you don’t need to tweak it at all.

Hello,But one item in that Red must be filled in,if not filled, then I can not create a new server.

Hello,

The problem has been resolved. Thank you for your reply.

Thank you
