Java小程序問題，帶有Java7＆8中的清單屬性

Question

我的應用程序將使用Java Applet Viewer顯示文檔，並且可以與Java6完美配合。 從Java7及更高版本開始，我無法查看文檔，因為applet無法加載該文檔。 我在下面使用的屬性。 有誰能建議我需要的更改

ANT腳本：

<target name="build.applet.manifest">
    <tstamp>
        <format property="build.time" pattern="MMMM dd yyyy" />
    </tstamp>

    <manifest file="${vfiles}/work/MANIFEST.MF">
        <attribute name="Built-By" value="${user.name}" />
        <attribute name="Class-Path" value="" />
        <attribute name="Trusted-Library" value="true" />
        <attribute name="Permissions" value="all-permissions" />
        <attribute name="Codebase" value="*" />
        <attribute name="Application-Name" value="${product.cea}" />
        <attribute name="Caller-Allowable-Codebase" value="*.com *.net" />
        <attribute name="Application-Library-Allowable-Codebase" value="*" />
        <attribute name="Implementation-Vendor" value="${imp-vendor}" />
        <attribute name="Implementation-Title" value="${product.cea}" />
        <attribute name="Implementation-Version" value="${project.version} build ${buildNumber} ${build.time}" />
    </manifest>
</target>

來自Oracle Java 7文檔

Caller-Allowable-Codebase屬性用於標識JavaScript代碼可以在沒有安全提示的情況下從中調用RIA的域。

從ip：8080調用applet時，清單中有* .com和* .net。 錯誤出現在日志中。

作為短期修復，您應該在清單的屬性列表中包括IP。 作為長期修復，您應該真正指定受信任的域，然后從那里運行小程序。

僅供參考，此屬性已添加，以降低小程序被盜並從另一個網站運行的風險。
