使用Java Generic SOAPClient(SAAJ)时抛出异常?

我正在尝试使用以下SOAPClient for Java(我从以下教程http://users.skynet.be/pascalbotte/rcx-ws-doc/saajpost.htm获得的详细信息)。

然而,似乎是在抛出异常。

这是我的代码:

javax.xml.soap.SOAPMessage msg;
MessageFactory mf = MessageFactory.newInstance();
msg = mf.createMessage();
SOAPPart part = msg.getSOAPPart();
StreamSource source = new StreamSource(new File("samples/input1.xml”));
part.setContent(source);
msg.saveChanges();

String endpoint = "http://ws1.parasoft.com/glue/calculator";

SOAPConnectionFactory scf = SOAPConnectionFactory.newInstance();
SOAPConnection conn = scf.createConnection();
javax.xml.soap.SOAPMessage response = conn.call(msg, endpoint);
TransformerFactory tff = TransformerFactory.newInstance();
Transformer tf = tff.newTransformer();
Source sc = response.getSOAPPart().getContent();
ByteArrayOutputStream ostream = new ByteArrayOutputStream(); 
StreamResult result = new StreamResult(ostream);
tf.transform(sc, result);
conn.close();

System.out.println(new String(ostream.toByteArray(), "UTF-8”));

在此示例中,我们假设samples/input1.xml包含以下内容:

<s11:Envelope xmlns:s11="http://schemas.xmlsoap.org/soap/envelope/">
   <s11:Body>
      <ns1:add xmlns:ns1="http://www.parasoft.com/wsdl/calculator/">
         <ns1:x>248</ns1:x>
         <ns1:y>365</ns1:y>
      </ns1:add>
   </s11:Body>
</s11:Envelope>

我正在尝试使用的示例Web服务可以在这里找到: http://www.service-repository.com/client/operations

运行上述Java代码(使用SOAPClient库)时,会抛出以下异常:

CAUSE:

    at com.sun.xml.internal.messaging.saaj.client.p2p.HttpSOAPConnection.call(HttpSOAPConnection.java:144)

使用这个网站,服务似乎正常运行,并且运行良好。

我甚至通过简单的cURL请求验证了服务端点处于活动状态,这令人惊讶地产生了正确的输出。

curl -H "Content-Type: text/xml; charset=utf-8" -H "SOAPAction:http://www.parasoft.com/wsdl/calculator/" -d@soap-request.xml http://ws1.parasoft.com/glue/calculator

产生的输出是:

<soap:Envelope xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xmlns:xsd='http://www.w3.org/2001/XMLSchema' xmlns:soap='http://schemas.xmlsoap.org/soap/envelope/‘>
    <soap:Body>
        <n:addResponse xmlns:n='http://www.parasoft.com/wsdl/calculator/‘>
            <n:Result xsi:type='xsd:float'>613.0</n:Result>
        </n:addResponse>
    </soap:Body>
</soap:Envelope>

所以,我的问题是:首先,Java代码出了什么问题?它怎么能修复?或者,是否还有其他更好/更可靠的通用SOAPClient库?

答案 0 :(得分:0)

通过在浏览器的url中附加?wsdl或以某种方式获得WSDL来查看WSDL。检查WSDl是否指定它是文档样式还是PRC样式,并基于该样式准备输入xml。

如果可能,请使用非常方便的SOAP UI工具。
