I suggest you sort directly from the datasource.
Two ways to do that, one is using ORDER BY in sql query itself another option is "HTML Template Exporter". It supports column sorting, hide/showing sections (folding), and pop-up windows. It is a utility available in the JasperShop.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
