1.加载驱动
例如要连接oracle数据库需要导入oracle的驱动包将驱动包放入到报表的安装路径(E:soft_install_path_mainiReport-5.1.0
ireportcorelocale)给下面。
2.PDF字体无法显示
之前本人在ireport1.3中做饼状图的报表，但在饼状图中无法显示出中文，所以改换ireport5不会出现类似的问题，
本人觉得还是高版本的工具还是比较还用一些。

解决方法：
iTextAsian.jar 这个包导入项目的classpath中，没有这个包的话，导出含有中文数据的PDF会报以下错误：
net.sf.jasperreports.engine.JRRuntimeException: Could not load the following font :
pdfFontName : STSong-Light
pdfEncoding : UniGB-UCS2-H(Chinese Siplified)
isPdfEmbedded : true
