异常原因：jrxml文件编译成jasper文件时的版本和代码运行时的版本不同
解决：处理jar包使它们用同一个jar包
分析：jasperreports-3.0.0.jar(编译成jasper文件时)中net.sf.jasperreports.engine.base.JRBaseReport的
private static final long serialVersionUID = 10200L;(反编译看到);
而jasperreports-1.0.3.jar(运行代码时)中
private static final long serialVersionUID = 10003L;
希望对看到的朋友有所帮助。
