{
	super(s);
	next = e;

 public synchronized Throwable getCause() 
{
	return next;
}

Overrides the getCause method of Throwable to return the next exception in the chain of nested exceptions.

 public synchronized Exception getNextException() 
{
	return next;
}

Get the next exception chained to this one. If the next exception is a MessagingException, the chain may extend further.

 public synchronized boolean setNextException(Exception ex) 
{
	Exception theEnd = this;
	while (theEnd instanceof MessagingException &&
	       ((MessagingException)theEnd).next != null) {
	    theEnd = ((MessagingException)theEnd).next;
	}
	// If the end is a MessagingException, we can add this 
	// exception to the chain.
	if (theEnd instanceof MessagingException) {
	    ((MessagingException)theEnd).next = ex;
	    return true;
	} else
	    return false;
}

Add an exception to the end of the chain. If the end is not a MessagingException, this exception cannot be added to the end.

 public synchronized String toString() 
{
	String s = super.toString();
	Exception n = next;
	if (n == null)
	    return s;
	StringBuffer sb = new StringBuffer(s == null ? "" : s);
	while (n != null) {
	    sb.append(";\n  nested exception is:\n\t");
	    if (n instanceof MessagingException) {
		MessagingException mex = (MessagingException)n;
		sb.append(mex.superToString());
		n = mex.next;
	    } else {
		sb.append(n.toString());
		n = null;
	    }
	}
	return sb.toString();
}

Override toString method to provide information on nested exceptions.
