"end-of-body reached" Error when consuming web service from 10GR1

Question

Hi all,
Im consuming a number of web services, all of which work fine apart from one which returns the error:
29266. 00000 - "end-of-body reached"
*Cause:    The end of the HTTP response body was reached.
*Action:   If the end of the HTTP response is reached prematurely, check if
the HTTP response terminates prematurely. Otherwise, end the
HTTP response.
I don't understand why this is happening and would really appreciate some help. I have checked the invoke procedure and there is a ' utl_http.end_response(http_resp);' call which online searching suggests can be a cause of the problem (if not used). The procedure which calls the service is:
function Events_Insert(id varchar2, pwd varchar2) return clob as
req opf_portal.pkg_call_web_services.request;
resp opf_portal.pkg_call_web_services.response;
aEventRecord varchar2(4000);
begin
req := opf_portal.pkg_call_web_services.new_request('Events_Insert', 'xmlns="<removed>');
aEventRecord:='<Options>

opf_portal.pkg_call_web_services.add_parameter(req, 'userid', 'xsd:string', id);
opf_portal.pkg_call_web_services.add_parameter(req, 'password', 'xsd:string', pwd);
opf_portal.pkg_call_web_services.add_parameter(req, 'aEventRecord', 'xsd:complexType', aEventRecord);
resp := opf_portal.pkg_call_web_services.invoke(req, '<removed>', '<removed>');
return resp.doc.getstringval();
end;

Answer 1

Incase anybody else encounters this problem, it was my XML that was invalid:
<EventBadgeRecord>
<Company>Oracle</Company>
<JobTitle>Consultant</JobTitle>
<Name>GregCox</Name>
<EventBadgeRecord>
was missing '/' in closing tag
