Run java and .jar app in terminal?

I've make/install some commandline programs in the past, but my tiny experience has failed me for this java file.

Ipswitch has a java program that they provide that provides encrypted ftp transport via https. Here is the relevant passage from their guide:

"
To "install" MOVEit Xfer under Java, simply extract the contents of the MOVEit Xfer for Java archive file into a directory. To run MOVEit Xfer, you will either need to have a Java runtime executable in your command-line "executable path" or explicitly provide a path to that executable in the command line.
"

OK, the folder contains a xfer.jar file, some example .bat files and the html/support for their help guide.

Seeing as it's a .jar and not a .java file makes me think I could drop it in my /local/ folder.

I believe /local is in my PATH, but I'm finding no java love.

I had thought the .jar was executable, but I'm showing my ignorance. How would my command look like with the executable it's looking for? thanx, sam
