Using JSP with Dreamweaver CC on Mac

I just got the latest CC creative suite installed on my new Mac. Our company uses JSP for web pages. Someone in the web team said we need to download the jsp add-on or our pages.  But, I can't download the JSP add-on for Dreamweaver because our company is not allowing me to download the creative cloud app.  When I go to update jsp pages it appears to work and save just fine though. Do I really need the add-in?
