I might be late to answer this, but I guess your correct choice would be Jxls. I faced a similar scenario in my module where I had to retain a certain template like logo,color,col-span,fixed column... So that's very hectic to write a separate java code and design it.
Jxls core is poi and syntactically similar to jstl, all you need is to map a array-list of bean with desired column in excel
