nervalreports
A lightweight report creation Java library
...Instead of the highly expensive way of well-known engines like Jasper Reports, where performance and data reiteration is a big and set aside problem (and also is the report design as a non-programming task), at Nerval Reports the data should be sent directly when iterating through it (ie: when using databases, one will create its report while iterating through the result set - instead of creating a bunch of collections to pass them to the library), and the design is mainly focused on programmer side. Also, one could include to its project just the exporters he/she is interested with, basing its choice on performance trade-offs, report file types and focused target projects. -
