The tools that are available in openxava is very good, I have been using this product from last two years only but never found any issue with it. Also, there are many ways to customize as per your need so you can do almost anything which suits your needs. It helps me create custom reports too in short period of time. Nothing much to dislike about this software, if you are looking for one best reporting system then definitely go for openxava because openxava provides all possible features which help us easily manage our data set or report sets,.
