Question about development with EPCM

Dear all,

If I wanna develop a set of custom iViews which will make use of the EPCM (client side code), is it a must to develop a JSPDynPage? Can I use DynPage only?

Besides, when developing a JSPDynPage, can I generate / construct the page layout by HTMLB from the java class and pass it to the jsp page?

Thanks for your kindly help
