[jdom-interest] NoSuchMethodError?

[Steve Beech]

Dear All,

When I try and run my app I get the following Exception:

Exception in thread "main" java.lang.NoSuchMethodError:
org.jdom.Element.getChildren(Ljava/lang/String;Lorg/jdom/namespace;)Ljava/ut
il/List;

I'm assuming that there is a file missing from my classpath but am not sure
which - or even if this is really the problem.

Any ideas?

Thanks
Steve.
