Applet 失败中的 SAX 解析器
我的源代码中有一行非常简单的代码：
XMLReader xmlReaderFactory = XMLReaderFactory.createXMLReader();
这在应用程序中完美地工作，但是，在小程序中，它尝试从服务器加载“.class”文件（没有类名，只有扩展名，正如您所看到的）然后无法给我一个解析器。

可能是什么问题呢？
I have a very simple line of code in my source:
XMLReader xmlReaderFactory = XMLReaderFactory.createXMLReader();
This works flawlessly from an application, however, from an applet, it attempts to load a ".class" file from the server (no classname, just the extension just as you see) and then fails to give me a parser.

What could be the problem?

看起来您似乎正在尝试配置 JRE 中以外的 SAX 实现的使用。 配置指向以至少两个空行开头的 Windows 文本文件。 SAX 实现可以通过系统属性 org.xml.sax.driver 进行配置，或者包含在名称为 META-INF/services/org.xml.sax.driver 的 jar 中的文件中。
It looks as if you are attempting to configure the use of a SAX implementation other than that in the JRE. The configuration is pointing to a Windows text files starting with at least two empty lines. SAX implementations may be configured through the system property
org.xml.sax.driveror contained in a file within a jar of the nameMETA-INF/services/org.xml.sax.driver.您可能会从服务器返回该类文件的 404 错误。 有关详细信息，请参阅此错误报告。
You might be getting back a 404 error from the server for that class file. See this bug report for details.
