Opening up JSP from another window

[Kemp Randy-W18971]

I have one JSP application and I wish to open up another window in JSP.  I was told to 
specify target="_window" in the url to pop up the JSP.  Where do I put this?  If my 
jsp is test.jsp, to I say.
http://localhost:8080/test.jsp target="_window"
Can someone suggest the proper format for the URL?
