我的任务
分享ireport打印问题
我用jetty跑的项目，在我本地，想做个用ireport打印功能，用的是Jaspersoft iReport Designer 4.5.1
项目中用的也是这个Jar包，在点击打印按钮额时候，跳转到controller里，向request里set相关参数，然后跳转到打印页面，页面代码

这个可能是设置的问题吧，你可以参考一下finereport的打印设置，总的来说我感觉用下来还是finereport在打印这一块做的不错，不管是产品，还是文档，都比较清晰明了。

网上查了，讲是编译的时候版本不兼容造成的...但是小弟真心不是熟悉这个，第一次接触...
请各位大侠帮忙解决...不胜感激....
