                                                          String type)
                                                   throws Exception

Return the ConfigValidator for specified component. The component is specified by classname and classloader. The ConfigValidator is loaded from specified location and has specified type. If the type is null then ConfigKit will attempt to guess the type based on schema location. The location parameter can be relative to the component (ie FooSchema.xml for class com.biz.Bar will load resource "/com/biz/FooSchema.xml" from classloader), absolute resource location in classloader (must start with "/") or null. If the location is null then it will assume resource name is the same name as class with the postfix "-schema.xml" added to classname. If no such resource is located in the ClassLoader then null is returned.

Parameters:

classname - the classname of component

classLoader - the classloader component loaded from

location - the location of schema

type - the type of schema

Returns:

the ConfigValidator

Throws:

Exception - if error creating validator
