应该不是很难，只要用JasperReporter+iReporter生成报表然后用JSF Facelets and the Flying Saucer Renderer输出就可以。
第一次用flying saucer，碰到些麻烦事，从网上copy过来的测试代码总是报以下错误： Exception in thread "main" org.xhtmlrenderer.util.XRRuntimeException: Can't load the XML resource (using TRaX transformer). org.w3c.dom.DOMException: NAMESPACE_ERR: An attempt is made to create or change an object in a way which is incorrect with regard to namespaces.itext版本是2.0.8，请问是什么原因导致的？
