Add JAR to startup with terminal window

Hello all, i am fairly new to Linux, I've been reading a bit about how to add an application to the startup execution in RHEL. I found this:

https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/5/html/Installation_Guide/s1-boot-init-shutdown-run-boot.html

But I would like for the application to open a terminal window automatically, is this possible? Any ideas?

I already have my JAR file...

Regards,
Hector
