java - 将代码从 Java 1.4 迁移到 Java 1.6 时找不到提供程序 org.apache.crimson.jaxp.SAXParserFactoryImpl

Question

我尝试将应用程序从 Java 1.4 迁移到 Java 1.6，但在 Java 1.6 上运行时遇到以下错误。请注意，在 Java 1.4/Java 1.5 上运行代码时不会出现该错误

javax.xml.parsers.FactoryConfigurationError:
    Provider org.apache.crimson.jaxp.SAXParserFactoryImpl not found
    at javax.xml.parsers.SAXParserFactory.newInstance(Unknown Source)

知道为什么会出现这个错误吗？它似乎指的是 crimson.jar ，它显然不存在，但为什么它指的是这个 jar ？

Apache - The org.apache classes, which have never been supported J2SE APIs but are used by the javax.xml package, have moved in 5.0 to com.sun.org.apache. package.internal so that they won't clash with more recent, developer-downloaded versions of the classes. Any applications that depend on the org.apache classes being part of the J2SE release must do one of the following to work in 5.0:

Code the application so it uses only the supported interfaces that are part of JAXP. Download the org.apache.xalan classes from Apache.
