Problem with < and > as parameter value

[Micael Ericsson (QIN)]

Hello

If I call a service and supply a parameter with <aa> as parameter value this is 
interpret in XML correctly as &lt;aa&gt;, but reaching Apache Soap (ver 2.2 on tomcat 
3.2.3) I get the following error message:
Exception: java.lang.Exception:SOAPException= SOAP-ENV:Client, Parsing error, response 
was: The element type "aa" must be terminated by the matching end-tag "
".

Is this a bug in apache soap toolkit?
Or have I missed some setting?

Thanks in advance,
Micael Ericsson
