Java6 XMLOutputFactory 유감

오늘 삽질하다가... 발견한 Sun의 Java6의 javax.xml.stream.?XMLOutputFactory 소스의 일부... -.-;;;;;

1. public abstract class XMLOutputFactory {
2. ...
3. /**
4. * Create a new instance of the factory using the default factory location
5. * mechanism (check env. variable, jaxp.properties, jar services manifest,
6. * in this order)
7. *
8. * @throws FactoryConfigurationError if an instance of this factory cannot be loaded
9. */
10. public static XMLOutputFactory newInstance() throws FactoryConfigurationError {
11.     return (XMLOutputFactory) FactoryFinder.find("javax.xml.stream.XMLOutputFactory",
12. "com.sun.xml.internal.stream.XMLOutputFactoryImpl");
13. }
14.  
15. /**
16. * Create a new instance of the factory
17. *
18. * @param factoryId Name of the factory to find; not the class name but the
19. *    property name to use
20. * @param classLoader classLoader to use
21. * @return the factory implementation
22. * @throws FactoryConfigurationError if an instance of this factory cannot be loaded
23. */
24. public static XMLInputFactory newInstance(String factoryId, ClassLoader classLoader)
25. throws FactoryConfigurationError {
26.     return (XMLInputFactory) FactoryFinder.find(factoryId, "com.sun.xml.stream.XMLOutputFactoryImpl", classLoader);
27. }
28. ...

뭐가 이상하냐고?

첫번째 함수와 두번째 함수의 리턴타입...

?XMLOutputFactory가 왜! ?XMLInputFactory를 create하는 것이냐!(버럭!!)

해결책: 그냥 우드스탁을 쓰던가... BEA의 StAX 참조구현을 쓰면 된다.
