java XML 解析问题 - FactoryConfigurationError：未找到提供程序

发布于 2024-09-06 10:45:55 字数 541 浏览 1 评论 0原文

我有一个 java 小程序，可以解析 xml 字符串。但是，运行以下代码：

DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document d = db.parse(xml);

生成以下错误：

javax.xml.parsers.FactoryConfigurationError: Provider <HTML> not found

我在发布之前检查过的一些论坛表明我需要将 2 个 jar 文件 - xercesImpl.jar 和 xmlParserAPIs.jar - 添加到我的 JRE_HOME/lib/ext 目录。但是，我不认为这是问题所在，因为该小程序当前托管在 2 个不同的网络服务器上，其中一个运行正常，而另一个则失败。我看了看，jre/lib/ext 目录中也没有这些 jar。

非常感谢任何帮助。

原文

I have a java applet that parses a string of xml. However, running the following code:

DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document d = db.parse(xml);

Generates the following error:

javax.xml.parsers.FactoryConfigurationError: Provider <HTML> not found

Some forums I've checked prior to posting indicated that I need to add 2 jar files - xercesImpl.jar and xmlParserAPIs.jar - to my JRE_HOME/lib/ext directory. However, I don't think this is the problem because this applet is currently hosted on 2 different webservers and one functions perfectly while the other fails. I looked, and neither have those jars in the jre/lib/ext directory.

Any help is greatly appreciated.
