windchill 開發java.security.AccessControlException: access denied 的問題處理

作爲一個windchill開發，常常會打開工作流查看節點信息什麼的，鬱悶的是谷歌瀏覽器老打不開工作流，IE瀏覽器吧又太low，經常頁面卡死。建議安裝一個32位谷歌瀏覽器

下面說一下常見的問題：
java.security.AccessControlException: access denied (“java.net.SocketPermission” “127.0.0.1:5002” “connect,resolve”)

打開java控制檯看見如下錯誤信息：

Java Plug-in 1.6.0_22
使用 JRE 版本 1.6.0_22-b04 Java HotSpot™ Client VM
用戶主目錄 = C:\Users\wonly.wu

c: 清除控制檯窗口
f: 終結在結束隊列上的對象
g: 垃圾收集
h: 顯示此幫助消息
l: 轉儲類載入程序列表
m: 打印內存使用
o: 觸發日誌記錄
q: 隱藏控制檯
r: 重新載入策略配置
s: 轉儲系統和部署屬性
t: 轉儲線程列表
v: 轉儲線程堆棧
x: 清除類載入程序高速緩存

然後工作流就加載不出來，我貼一下解決辦法：

step1：找到如下兩個文件
C:\Program Files (x86)\Java\jdk1.8.0_144\jre\lib\security\java.policy
C:\Program Files (x86)\Java\jre1.8.0_144\lib\security\java.policy

step2:在文件中增加：permission java.security.AllPermission;

// Standard extensions get all permissions by default

grant codeBase "file:${{java.ext.dirs}}/*" {
        permission java.security.AllPermission;
};

// default permissions granted to all domains

grant {
        // Allows any thread to stop itself using the java.lang.Thread.stop()
        // method that takes no argument.
        // Note that this permission is granted by default only to remain
        // backwards compatible.
        // It is strongly recommended that you either remove this permission
        // from this policy file or further restrict it to code sources
        // that you specify, because Thread.stop() is potentially unsafe.
        // See the API specification of java.lang.Thread.stop() for more
        // information.
        permission java.lang.RuntimePermission "stopThread";

        // allows anyone to listen on dynamic ports
        permission java.net.SocketPermission "localhost:0", "listen";

        // "standard" properies that can be read by anyone

        permission java.util.PropertyPermission "java.version", "read";
        permission java.util.PropertyPermission "java.vendor", "read";
        permission java.util.PropertyPermission "java.vendor.url", "read";
        permission java.util.PropertyPermission "java.class.version", "read";
        permission java.util.PropertyPermission "os.name", "read";
        permission java.util.PropertyPermission "os.version", "read";
        permission java.util.PropertyPermission "os.arch", "read";
        permission java.util.PropertyPermission "file.separator", "read";
        permission java.util.PropertyPermission "path.separator", "read";
        permission java.util.PropertyPermission "line.separator", "read";

        permission java.util.PropertyPermission "java.specification.version", "read";
        permission java.util.PropertyPermission "java.specification.vendor", "read";
        permission java.util.PropertyPermission "java.specification.name", "read";

        permission java.util.PropertyPermission "java.vm.specification.version", "read";
        permission java.util.PropertyPermission "java.vm.specification.vendor", "read";
        permission java.util.PropertyPermission "java.vm.specification.name", "read";
        permission java.util.PropertyPermission "java.vm.version", "read";
        permission java.util.PropertyPermission "java.vm.vendor", "read";
        permission java.util.PropertyPermission "java.vm.name", "read";
		
		permission  java.security.AllPermission;//增加此行代碼
		
		
};
