for further information.
This class contains a static method for creating an instance of a
class from an explicit class name. It tries to use the thread's context
ClassLoader if possible and falls back to using
Class.forName(String).
This code is designed to compile and run on JDK version 1.1 and later
including versions of Java 2. |
| Methods Summary |
|---|
| static java.lang.ClassLoader | getClassLoader()Figure out which ClassLoader to use. For JDK 1.2 and later use
the context ClassLoader.
Method m = null;
try {
m = Thread.class.getMethod("getContextClassLoader", (Class[]) null);
} catch (NoSuchMethodException e) {
// Assume that we are running JDK 1.1, use the current ClassLoader
return NewInstance.class.getClassLoader();
}
try {
return (ClassLoader) m.invoke(Thread.currentThread(), (Object[]) null);
} catch (IllegalAccessException e) {
// assert(false)
throw new UnknownError(e.getMessage());
} catch (InvocationTargetException e) {
// assert(e.getTargetException() instanceof SecurityException)
throw new UnknownError(e.getMessage());
}
| | static java.lang.Object | newInstance(java.lang.ClassLoader classLoader, java.lang.String className)Creates a new instance of the specified class name
Package private so this code is not exposed at the API level.

if (classLoader == null) {
