Debugging with HTML

Perhaps this is perfectly normal as its been a while since I played with web development but I will ask anyway:

Basically I have a REST servlet running using jersey and I have connected it to a simple SAPUI5 table. Now in debug mode I can modify the servlet (java) part and the server updates but this doesn't appear to be the case for the HTML (static) part. I want to avoid using JSP or servlets for the client rendering as I want a pure html2rest architecture.

Note I don't need to debug the html, I just want it to update as this slows down my development a little as I need to stop/start my server, re-authenticate etc.

thanks,

peter
