Handling soap fault messages

Question

Hi All,
I had webservice and am able to pass geneate proper response based on client request but when they are making invalid request i.e
removing some tag or making syntax related mistake, in response i'm getting exception related to <faultcode>soap:Client</faultcode>.
I check my logs and it seems that the request is not coming to my service. The exception/response seems to generated by web server.Instead of webserver, i want to pass my customised exception for eg."invalid request".Can I do it?? If yes, how can i do it?
Also, this webservice is being consumed by lotsa users, so if possible i don't want to do code change in existing services.If simply by setting some configuration or writing a wrapper might do.
Really appreciated if someone reply with proper answer.
Thanks in advance.
Cheers,
Cha

you can use
PROCEDURE p_check_fault(p_resp IN OUT NOCOPY response) as
fault_node xmltype;
fault_code varchar2(256);
fault_string varchar2(32767);
begin
DBMS_OUTPUT.PUT_LINE('Checking fault string...');
fault_node := p_resp.doc.extract('/env:fault',
'xmlns:env="http://schemas.xmlsoap.org/soap/envelope/');
if (fault_node is not null) then
DBMS_OUTPUT.PUT_LINE('Fault!!!...');
fault_code := fault_node.extract('/env:fault/faultcode/child::text()',
'xmlns:env="http://schemas.xmlsoap.org/soap/envelope/').getstringval();
fault_string := fault_node.extract('/env:fault/faultstring/child::text()',
'xmlns:env="http://schemas.xmlsoap.org/soap/envelope/').getstringval();
DBMS_OUTPUT.PUT_LINE('CODE:' || fault_code || '.Msj:' || fault_string);
raise_application_error(-20993, 'Error: '
|| fault_code || ' - ' || fault_string);
end if;
end p_check_fault;
