我的任务是将我们古老的 Java 小程序从小程序标签更新为对象标签,因为小程序标签已经被弃用了一段时间。该小程序必须可以追溯到早期的 Java 1.6 版本,在可追溯到 IE6 的浏览器上。我制作了以下对象标签来处理这个问题,根据用户是否使用 IE 来切换它们。<% %> 中的语句评估良好,只需填写 jar 文件等。

<% If userIsIE > 0 Then %>
        <object type="application/x-java-applet" classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93" height="0" width="0"> 
            <param name="code" value="<% =MainClass %>" />
            <param name="archive" value="<% =Archives %>" />
            <param name="persistState" value="false" />
        </object>
        <% Else %>
        <object classid="java:<% =MainClass %>" type="application/x-java-applet" archive="<% =Archives %>" height="0" width="0">
            <param name="code" value="<% =MainClass %>" />
            <param name="archive" value="<% =Archives %>" />
            <param name="persistState" value="false" />
        </object>
<% End If %>

它适用于我尝试过的所有浏览器,以及我尝试过的所有 Java 版本,除了我的同事发现的一个特定情况:使用 Java 1.6.0_20 运行 IE9(可能还有其他一些旧版本,未经证实)导致页面崩溃,将其留在我的桌面上:

它看起来像 JVM 本身中的空指针异常。如果我摆脱了我拥有的“IE 特定”版本并在 Else 之后只使用第二个版本,它仍然会发生。我也尝试将高度和宽度更改为非零值,认为它可能会对这些值做一些奇怪的事情,但没有。如果我回到使用小程序标签,同时保持所有参数和设置相同,则不会发生这种情况。现在,如果我纯粹为自己做这件事,我会接受这是旧 JVM 中的一个错误,并要求人们升级到最新版本的 Java(运行良好),但我们的许多客户都是企业用户,非常“ “粘性”的 IT 部门需要很长时间才能推出更新,或者甚至不知道 Java 是什么的用户,更不用说知道如何更新它了。我是否会放弃并继续使用小程序标签,直到浏览器完全停止支持它们?有没有我没有尝试过的技巧来完成这项工作?

编辑:我做了更多测试,看起来 java 测试页面本身(http://www.java.com/en/download/testjava.jsp)也会导致同样的崩溃。也许我只需要使用小程序标签,直到我们所有的客户都更新了,如果它太糟糕以至于官方的 java 测试小程序甚至无法加载。

用于deployJava.js编写小程序元素。它旨在确保为该浏览器编写正确的元素。

问题出在本机 C 框架中,看起来像 JDK 错误。

此处报告了与 JDK 6u 19 及更高版本类似的错误。

修复看起来像是转移到 Java 7
