無法在本地主機上運行Java小程序

我試圖在運行在resin中的本地主機上運行Java小程序。我有一個包含如下的JSP文件applet2.jsp：無法在本地主機上運行Java小程序

Testing an applet. 

<IMG SRC="/static/images/tabTrackerRollM.gif"><BR> 

<APPLET NAME="tracker" CODE="com.my.package" ARCHIVE="/applets/my_applet.jar" WIDTH="100%" HEIGHT="300" VIEWASTEXT MAYSCRIPT> 
<param name=updateUrl value="http://localhost/test/appletSample3.jsp"> 
<param name=bgColor value="0,0,0"> 
<param name=updateFrequency value=4000> 
</APPLET>

但是，每當我試圖運行在瀏覽器中applet的我總是得到以下錯誤信息：

當檢查Java控制檯，我發現：

它基本上說my_applet.jar丟失。但是，當我試圖通過指向http://localhost/applet/my_applet.jar與我的瀏覽器訪問它，它實際上存在：

我也試圖去Java.com檢查，如果我有最新的Java： enter image description here

我下面的平臺上： OS：的Windows 7（64） 的Java： JDK 1.7（64）

我還清除了控制面板中的java小程序緩存，將瀏覽器安全設置爲中等並清除瀏覽器緩存。

我們必須在瀏覽器上運行之前對applet進行簽名，然後才嘗試對applet Jar進行簽名。這裏是簽名命令。

您應該在命令提示符下的同一個目錄中。

1.keytool -genkey -keyalg rsa -alias m4key //m4key unique key 
2.keytool -export -alias m4key -file bmcert.crt //bmcert.crt certificate name 
3.jar tvf Jarname.jar verify jar 
4.jarsigner Jarname.jar m4key 
5.jarsigner -verify -verbose -certs JarnameJarname.jar

嗨，喬治！是的，我忘記提及它已經簽署。 – epsac 2014-09-12 12:14:59
