I’m using the following code to send a .xml
via SOAP
package consumirwebserviceporrequisicaoxml;
import java.io.ByteArrayInputStream;
import java.io.IOException;
import java.io.StringWriter;

import javax.xml.transform.Transformer;

public class ConsumirWebServicePorRequisicaoXML {

public static void main(String[] args) throws SOAPException, IOException {
// TODO code application logic here
// TODO code application logic here
String requestSoap;//requisicao/request no formato xml, repare que isto foi copiado da regiao destacada em azul na figura 1
requestSoap = "<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:tem=\"http://tempuri.org/\">\n"

SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance();
SOAPConnection soapConnection = soapConnectionFactory.createConnection();
String url = "http://ws.correios.com.br/calculador/CalcPrecoPrazo.asmx";//url do webservice nao e a url do wsdl do webservice, repare que isto foi copia da parte vermelha da figura 1
MimeHeaders headers = new MimeHeaders();
headers.addHeader("Content-Type", "text/xml");
//exclua esta regiao caso o webservice nao possua a proprieade SOAPAction
headers.addHeader("SOAPAction", "http://tempuri.org/CalcPrazo"); // header SOAPAction e sua respectiva url, esta url muda de webservice para webservice. Alguns webservice nao possuem esta proprieade, nestes webservice esta linha deve ser excluida
// o valor "http://tempuri.org/CalcPrazo" foi obtido com base na região destacada em verde da figura 2.
//fim da regiao a ser excluida caso o webservice nao possua a proprieade SOAPAction
MessageFactory messageFactory = MessageFactory.newInstance();
SOAPMessage msg = messageFactory.createMessage(headers, (new ByteArrayInputStream(requestSoap.getBytes())));
SOAPMessage soapResponse = soapConnection.call(msg, url);
Document xmlRespostaARequisicao=soapResponse.getSOAPBody().getOwnerDocument();
System.out.println(passarXMLParaString(xmlRespostaARequisicao,4));//imprime na tela o xml de retorno.
}
public static String passarXMLParaString(Document xml, int espacosIdentacao){
try {
//set up a transformer
TransformerFactory transfac = TransformerFactory.newInstance();
transfac.setAttribute("indent-number", new Integer(espacosIdentacao));
Transformer trans = transfac.newTransformer();
trans.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
trans.setOutputProperty(OutputKeys.INDENT, "yes");
//create string from xml tree
StringWriter sw = new StringWriter();
StreamResult result = new StreamResult(sw);
DOMSource source = new DOMSource(xml);
trans.transform(source, result);
String xmlString = sw.toString();
return xmlString;
}
catch (TransformerException e) {
// TODO Auto-generated catch block
e.printStackTrace();
System.exit(0);
}
return null;
}
}
However, how do I do for the content of requestSoap
come from a file .xml
and not of values entered in the variable?
