需要的jar包:
需要的js文件:(可以通过http://www.highcharts.com/download下载highcharts对应的js文件)
下面是一些主要部分

This is the description of my J2EE component This is the display name of my J2EE component SaveAsImage com.foxconn.highcharts.demo.SaveAsImage SaveAsImage /SaveAsImage basic_line.jsp
servlet部分

注意：请下载源码的同学，将源码中的
/* else if (type.equals("application/pdf")) { ext = "pdf"; t =(Transcoder) new PDFTranscoder(); }*/ 上面的注释去掉，程序是可以成功导出pdf的。
