Re: [ebxmlms-general] Cannot load Delivery Handler

[Patrick Y. <kc...@ce...>]

We used reflection API to load the delivery handler. And 
InstantiationException is thrown only when Class.newInstance() is 
called. According to JavaDoc of J2SE:

|InstantiationException 
<http://java.sun.com/j2se/1.4.2/docs/api/java/lang/InstantiationException.html>| 
- if this |Class| represents an abstract class, an interface, an array 
class, a primitive type, or void; or if the class has no nullary 
constructor; or if the instantiation fails for some other reason.

So is your custom delivery handler having a default constructor (i.e. a 
constructor with no argument)?
