客户端applet调用dll,折腾一晚上搞定

1.生成证书(cjzk.keystore) keytool -genkeypair -keyalg RSA -keysize 2048 -sigalg SHA1withRSA -validity 36000 -alias www.cjzk.com -keystore cjzk.keystore 2.导出证书(cjzk.cer) keytool -exportcert -alias www.cjzk.com -keystore cjzk.keystore -file cjzk.cer -rfc 3.对jar包签名(还有ic.jar依赖的jar最好都签名一下,我用的JNA两个jar都签名了) jarsigner -keystore cjzk.keystore ic.jar www.cjzk.com jarsigner -keystore cjzk.keystore jna.jar www.cjzk.com jarsigner -keystore cjzk.keystore platform.jar www.cjzk.com 4.创建ic.policy文件(内容如下) keystore file:cjzk.store , JKS ; grantsignedBy www.cjzk.com { permission java.io.FilePermission ALLFILES , read ; }; 5.注册ic.policy文件 打开C:\Program Files\Java\jre6\lib\security\java.security文件 找到如下两行 policy.url.1=file:${java.home}/lib/security/java.policy policy.url.2=file:${user.home}/.java.policy 在它们下面添加 policy.url.3=file:C:/Program Files/Java/jre6/lib/security/ic.policy 6.jsp中applet调用 applet id= IcCardApplet name= IcCardApplet code= little.ant.pingtai.applet.IcCardApplet.class archive= little/ant/pingtai/applet/ic.jar,little/ant/pingtai/applet/jna.jar,little/ant/pi ngtai/applet/platform.jar width= 200px height= 200px /applet script type= text/javascript function test(){ var str = window.document.IcCardApplet.hello(); alert(str); } /script input type= button value= 测试Dll onclick= test()
