[英]Web-Service invoke with JavaScript
I am developing my first Web-Service at the moment. 目前,我正在开发我的第一个Web服务。
Client is developed with JavaScript. 客户端是使用JavaScript开发的。
My problem is that it did not work. 我的问题是它没有用。 I do not know what my problem is.
我不知道我的问题是什么。
I think it is a mistake on the client site. 我认为这是客户端网站上的错误。 I tried it with an Java Web-Service Client and there it works.
我使用Java Web服务客户端进行了尝试,并且可以正常工作。
Web-Service: 网络服务:
import javax.jws.*;
import javax.jws.soap.SOAPBinding;
@WebService(name="TicketWebService", targetNamespace = "http://my.org/ns/")
@SOAPBinding(style = SOAPBinding.Style.RPC)
public class TicketWebService {
@WebMethod(operationName="getContact")
public String getContact()
{
return "Hallo Hans!!!";
}
}
Publish on Server: 在服务器上发布:
import javax.swing.JOptionPane;
import javax.xml.ws.Endpoint;
public class PublishWsOnServer
{
public static void main( String[] args )
{
Endpoint endpoint = Endpoint.publish( "http://localhost:8080/services",
new TicketWebService() );
JOptionPane.showMessageDialog( null, "Server beenden" );
endpoint.stop();
}
}
Client: 客户:
<html>
<head>
<title>Client</title>
<script language="JavaScript">
function HelloTo()
{
var endpoint = "http://localhost:8080/services";
var soapaction = "http://localhost:8080/services/getContact";
xmlHttp = getXMLHttp();
xmlHttp.open('POST', endpoint, true);
xmlHttp.setRequestHeader('Content-Type', 'text/xml;charset=utf-8');
xmlHttp.setRequestHeader('SOAPAction', soapaction);
xmlHttp.onreadystatechange = function() {
alert(xmlHttp.responseXML);
}
xmlHttp.send(request);
}
</script>
</head>
<body onLoad="HelloTo()" id="service">
Body in Client
</body>
</html>
The alert does not work... 警报不起作用...
I'm pretty new at JAX-WS but I think that maybe your problem is not in the client side. 我在JAX-WS上还很新,但是我认为也许您的问题不在客户端。 First of all, here you have a HelloWorld example that works fine, if you look into the code you will see that in the web service implementation the annotation WebService is defined as
首先, 这里有一个很好的HelloWorld示例,如果您仔细研究代码,将会发现在Web服务实现中,注释WebService被定义为
@WebService(endpointInterface = "com.mkyong.ws.HelloWorld")
which is the full package of your "TicketWebService". 这是“ TicketWebService”的完整软件包。 Another difference is that the example defines an interface (marked with the @WebService annotation) and then implements it, including the @WebService also in the implementation.
另一个区别是该示例定义了一个接口(标有@WebService批注),然后实现了该接口,在实现中也包括了@WebService。 I don't think this is mandatory, but is a good practice to define the interface.
我不认为这是强制性的,但是定义接口是一个好习惯。
