pplet虽然已经基本上没人用了。但是它还有一些应用场景的，为了兼容性。为了各个浏览器，不能直接直接写<applet>标签，最后考虑一下测试了几天，最后还是写如下比较适合多个浏览器兼容，希望对大家有所帮助
<%@page language="java" import="java.util.*" pageEncoding="UTF-8"

//该写法兼容Firefox、IE、Chrome浏览器
//applet加载类
String appletClass = "cn.com.pansky.frame.cqap.printer.CQAPPrinterApplet.class";
//依赖jar包
目录 String appletCodebase="applets";
String appletJar = "commons-logging-1.1.1.jar,commons-collections-2.1.1.jar,jfreechart-1.0.12.jar,jcommon-1.0.15.jar";
int width = 300, height = 200;
//查询参数
String queryString = request.getQueryString();
if (queryString == null) {
queryString = "";
}
queryString = "/otp/cqap/cqap-printer.servlet.jsp?" + queryString;
