forEach confusion

Hi,
i'm trying to do this:

   for int (i=0; i < paypalResponse.getErrors().length; i++) {
     String message= paypalResponse.getErrors(i);
   }

like so in jx

        <jx:forEach var="item" items="${paypalResponse.getErrors()}">
        <tr>
            <td>${item}</td>
        </tr>
        </jx:forEach>

but this only returns an object and not the object value. What am I missing?
I tried ${item[0]} but that returns nothing.

regards

Andrew

Hi Jason,
that worked a treat, many thanks. If paypal themselves don't know what
they're doing, it may well be time to find another merchant service!!!

Andrew

Well, not to knock down their developers, but that post doesn't look 
like an authoritative sample of working code. ;-)  First of all it isn't 
even valid Java syntax.  It's also different than what you pasted in 
since theirs doesn't try to assign the ErrorType object to a String 
variable.  In short, it doesn't do what you want.

OK, so call a method of the ErrorType class that returns the descriptive 
string you want.  Perhaps .getShortMessage() or .getLongMessage()?  You 
just need to look at what the API provides.

The fact that it's telling you it's got an ErrorType object indicates 
the forEach looping is working correctly.

Hi Jason,

Does that really work?


So the Paypal developers say!

I mean the actual value held in the object. Even with item.toString() I am
still getting:

com.paypal.soap.api.ErrorType@727c61b7

type returns. What I want is to access the contents within object which is a
descriptive string describing why a credit card check was rejected.

HTH

Does that really work?  I'm guessing that paypalResponse is a 
com.paypal.soap.api.AbstractResponseType ... if that's right then the 
online javadocs say getErrors(int i) does not return a String, it 
returns an ErrorType object.

I assume by "the object value" you mean a String representation of it? 
Try ${item.toString()} ?
