Here your request should be something like this <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"; xmlns:typ="http://ws.cathdb.info/Types";> <soapenv:Header/> <soapenv:Body> <typ:SubmitBlast> <typ:query_data xsi:type="FastaRecord" > <header>tess</header> <Sequence></Sequence> </typ:query_data> </typ:SubmitBlast> </soapenv:Body> </soapenv:Envelope> Try to invoke this service ether using an XMLBean client or an ADB client.
