RE: Creating customer Exception class

["Clapham, Paul" <pclapham@xxxxxxxxxxxxx>]

I would say you also need to override the "public Throwable getCause()" method 
to return a reference to the Exception that you are wrapping. (Assuming you are 
using Java 1.4, that is.) And I wouldn't have a message called 
"getAppLevelMsg()", I would override "public String getMessage()" from 
Exception.

But now that I look through the API documentation some more, I see there's 
already a (1.4) constructor "new Exception(String message, Throwable cause)"; 
you could just override Exception and use that constructor and your work would 
be done.

Subject: Creating customer Exception class

would below be a good way to create a customer Exception class that contains 
application level error message?
 
public class MyException extends Exception {
    private String appLevelMsg;
 
    public MyException(String appLevelMsg, Exception ex) {
        super(ex);
        this.appLevelMsg = appLevelMsg;
   }
 
    public String getAppLevelMsg() {
        return appLevelMsg;
    }
}
