Do SOAP Web services support only “POST” http method

Question

I faced this question on one of interviews, so could you please tell whether SOAP Web services support only \"POST\" http method or there is some way to accept other methods

Answer 1

This is an implementation of GET in SOAP:

@WebServiceProvider(targetNamespace="http://attachment.service.soap.com/download")
@ServiceMode(value = javax.xml.ws.Service.Mode.MESSAGE)
@BindingType(value = HTTPBinding.HTTP_BINDING)
public final class ImageDownloadServiceProvider implements Provider {
    @Resource
    private WebServiceContext wsContext;

    @Override
    public DataSource invoke(DataSource request) {
        if (wsContext == null)
            throw new RuntimeException("dependency injection failed on wsContext");
        MessageContext msgContext = wsContext.getMessageContext();
        HttpExchange exchange = (HttpExchange) msgContext.get("com.sun.xml.internal.ws.http.exchange");
        String filename = exchange.getRequestURI().getQuery().replace("file=", "");
        switch ((String) msgContext.get(MessageContext.HTTP_REQUEST_METHOD)) {
        case "GET":
            return doGet(filename);
        default:
            throw new HTTPException(405);
        }
    }

    private DataSource doGet(String filename) {
        FileDataSource fds = new FileDataSource(filename);
        MimetypesFileTypeMap mtftm = new MimetypesFileTypeMap();
        mtftm.addMimeTypes("image/jpeg jpg");
        fds.setFileTypeMap(mtftm);
        return fds;
    }
