Question

When I was doing some experiment on JSF Exception Handling, I hit following error. Basically I don’t really understand what this error trying to tell? Hope you guys can help me to decode the message.

[ERROR   ] Uncaught.init.exception.thrown.by.servlet

[ERROR   ] Uncaught.init.exception.thrown.by.servlet
[ERROR   ] Uncaught.init.exception.thrown.by.servlet
[ERROR   ] Error Page Exception:

This is what I configure in faces-config.xml:

<factory>
  <exception-handler-factory>
    org.huahsin.exception.JsfExceptionHandlerFactory
  </exception-handler-factory>
</factory>

This is the JsfExceptionHandlerFactory.java:

public class JsfExceptionHandlerFactory extends ExceptionHandlerFactory {

    private ExceptionHandlerFactory factory;

    public JsfExceptionHandlerFactory(JsfExceptionHandlerFactory factory) {
        this.factory = factory;
    }

    /* (non-Javadoc)
     * @see javax.faces.context.ExceptionHandlerFactory#getExceptionHandler()
     */
    @Override
    public ExceptionHandler getExceptionHandler() {
        ExceptionHandler result = new JsfExceptionHandler(factory.getExceptionHandler());
        return result;
    }

}

This is the JsfExceptionHandler.java:

public class JsfExceptionHandler extends ExceptionHandlerWrapper {

    private ExceptionHandler handler;

    public JsfExceptionHandler(ExceptionHandler handler) {
        this.handler = handler;
    }

    @Override
    public ExceptionHandler getWrapped() {
        return this.handler;
    }

    @Override
    public void handle() throws FacesException {

        System.out.println("handle");
    }
}

Thanks to @Ravi, I have the problem solved in JsfExceptionHandlerFactory class by replacing the constructor argument with ExceptionHandlerFactory. Below is the updated code.

public class JsfExceptionHandlerFactory extends ExceptionHandlerFactory {

    private ExceptionHandlerFactory factory;

    public JsfExceptionHandlerFactory(ExceptionHandlerFactory factory) {
        this.factory = factory;
    }

    /* (non-Javadoc)
     * @see javax.faces.context.ExceptionHandlerFactory#getExceptionHandler()
     */
    @Override
    public ExceptionHandler getExceptionHandler() {
        ExceptionHandler result = new JsfExceptionHandler(factory.getExceptionHandler());
        return result;
    }

}
