public class ResourceClass

extends Resource

'Resource' located by discovery. Naming of methods becomes a real pain ('getClass()') so I've patterned this after ClassLoader... I think it works well as it will give users a point-of-reference.

Method Detail

setLog

public static void setLog(org.apache.commons.logging.Log _log)

loadClass

public java.lang.Class loadClass()

Get the value of resourceClass. Loading the class does NOT guarentee that the class can be instantiated. Go figure. The class can be instantiated when the class is linked/resolved, and all dependencies are resolved. Various JDKs do this at different times, so beware: java.lang.NoClassDefFoundError when calling Class.getDeclaredMethod() (JDK14), java.lang.reflect.InvocationTargetException (wrapping java.lang.NoClassDefFoundError) when calling java.lang.newInstance (JDK13), and who knows what else..

Returns:

value of resourceClass.

toString

public java.lang.String toString()

Overrides:

toString in class Resource
