Ireport客戶端打印

1.新建一個web項目Outireport。如圖：

2.向lib導入ireport報表需要的包jasperreports-4.0.2.jar, jasperreports-applet-4.0.2.jar, commons-collections-2.1.jar, commons-logging-1.0.2.jar, groovy-all-1.7.5.jar, iText-2.1.7.jar, iTextAsian.jar(這幾個表可能有個別包不是必須)。如圖：

3.在WebRoot中新建一個名為ireport的目錄，里面存放打印的ireport報表，我這里是一個用戶的報表。如圖：

4.在src中新建一個applet的目錄，在applet中新建一個名為IreportServlet.java的servlet。代碼如下：
