SAAJ response - invalid SOAP envelope

[Stephen Chell]

I'm using SAAJ 1.2 (from jwsdp-1.3) and JDK 1.4.2_03.

I've written a client application that uses the SAAJ api to send a
SOAP message to a servlet. The servlet successfully receives the
message and returns a SOAP response containing a single element in the
SOAP body. The client receives the response and writes its content to
standard out via the SOAPMessage.writeTo() method. The response
received looks correct:

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Body>
<eai:Response xmlns:eai="urn:nz:govt:eai">SUCCESS</eai:Response>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

.... but when I try to access the soap envelope as follows:

SOAPMessage response = connection.call(message, endpoint);
response.writeTo(System.out);
SOAPPart part = response.getSOAPPart();
SOAPEnvelope env = part.getEnvelope();

The last line in the above code fragment throws the following
exception (see below). Does anyone know whats causing this? Please
help.

Thanks in advance ...
