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"	contentType="text/html; charset=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;%><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html>	<head>		<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE8" />		<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />		<title>打印</title>	</head>	<body>		<!-- 环境判断 -->		<!--"CONVERTED_APPLET"-->		<!-- CONVERTER VERSION 1.1 -->		<SCRIPT LANGUAGE="JavaScript"><!--    var _info = navigator.userAgent; var _ns = false;    var _ie = (_info.indexOf("MSIE") > 0 && _info.indexOf("Win") > 0 && _info.indexOf("Windows 3.1") < 0);//--></SCRIPT>		<COMMENT>		<SCRIPT LANGUAGE="JavaScript1.1"><!--    var _ns = (navigator.appName.indexOf("Netscape") >= 0 && ((_info.indexOf("Win") > 0 && _info.indexOf("Win16") < 0 && java.lang.System.getProperty("os.version").indexOf("3.5") < 0) || (_info.indexOf("Sun") > 0) || (_info.indexOf("Linux") > 0)));//--></SCRIPT></COMMENT>		<!-- applet展示 --><%--<applet width=460 height=160>    <PARAM NAME=CODE     VALUE="<%=appletClass%>">	<PARAM NAME=CODEBASE VALUE="applets">	<PARAM NAME=ARCHIVE  VALUE="<%=appletJar%>">    <PARAM NAME="type"   VALUE="application/x-java-applet;version=1.2.2">    <PARAM NAME="scriptable" VALUE="false">    <PARAM NAME="REPORT_URL" VALUE ="<%=queryString%>"></applet>--%>		<OBJECT classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93"			type="application/x-java-bean;version=1.1.2"			codebase="http://java.sun.com/products/plugin/1.1.2/jinstall-112-win32.cab#Version=1,1,2,0"			WIDTH="<%=width%>" HEIGHT="<%=height%>">			<PARAM NAME=CODEBASE VALUE="<%=appletCodebase %>">			<PARAM NAME=ARCHIVE VALUE="<%=appletJar%>">			<PARAM NAME=CODE VALUE="<%=appletClass%>">			<PARAM NAME="scriptable" VALUE="false">			<PARAM NAME="REPORT_URL" VALUE="<%=queryString%>">			<comment><EMBED type="application/x-java-bean;version=1.1.2"				pluginspage="http://java.sun.com/products/plugin/1.1.2/plugin-install.html"				CODE="<%=appletClass%>" CODEBASE="<%=appletCodebase %>"	ARCHIVE="<%=appletJar %>"				WIDTH="<%=width%>" HEIGHT="<%=height%>"				REPORT_URL="<%=queryString%>" scriptable=false>				<noembed></noembed>			</EMBED></comment>		</OBJECT>	</body></html>
