我正在尝试编写一个基于Java的Web服务客户端，以通过网络IP来使用安全的Web服务。这是我的第一次，所以我需要一些认真的帮助。我从我的供应商那里获得的是三个不同的.cer文件和一个wsdl链接。经过一些研究我做了什么创建了一个带有keytool -import -file myCert.cer -alias testkey -keystore test.ks的新密钥库，并将这三个.cer文件添加到其中，没有别的。然后我写了下面的代码进行测试。告诉我是否需要做任何其他事情才能建立成功的连接。
import java.io.ByteArrayInputStream;
import java.io.StringWriter;
import java.nio.charset.Charset;
import javax.xml.soap.*;
import javax.xml.transform.*;
import javax.xml.transform.stream.*;
public class SOAPClient {
public static void main(String[] args) {
String response = null;
try {
String request = "my xml based SOAP string";
System.setProperty("javax.net.ssl.keyStore", "/web/cert/test.ks");
System.setProperty("javax.net.ssl.keyStorePassword", "password");
// Create SOAP Connection
SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance();
String url = "https://example.com:31746/Service/service.serviceagent";
MessageFactory messageFactory = MessageFactory.newInstance();
SOAPConnection soapConnection = soapConnectionFactory.createConnection();
SOAPMessage soapMessage = messageFactory.createMessage(new MimeHeaders(), new ByteArrayInputStream(request.getBytes(Charset.forName("UTF-8"))));
// Send SOAP Message to SOAP Server
SOAPMessage soapResponse = soapConnection.call(soapMessage, url);
// Process the SOAP Response
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
Source sourceContent = soapResponse.getSOAPPart().getContent();
StringWriter outWriter = new StringWriter();
StreamResult result = new StreamResult( outWriter );
transformer.transform(sourceContent, result);
StringBuffer sb = outWriter.getBuffer();
response = sb.toString();
System.out.println(response);
soapConnection.close();
} catch (Exception e) {
System.err.println("Error occurred while sending SOAP Request to Server");
e.printStackTrace();
}
//return response;
}
}
但是当我通过命令行将这个java代码作为独立程序运行时（因为我没有其他测试方法），我在屏幕上得到以下异常。

答案 0 :(得分：2)
我认为这不是潜在问题，但您需要按javax.net.ssl.keyStore更改javax.net.ssl.trustStore。
trustStore 确定是否为远程 authenticationcredentials（以及连接）应该是 值得信赖的。
keyStore 确定要发送到的身份验证凭据 远程主机。
可能错误是由于您的请求不是有效的SOAP消息，并且它导致服务器的空响应。
String request = "my xml based SOAP string";
我建议您调试互换的soap消息并使用从WSDL生成的JAX-WS客户端，而不是从头开始构建SOAP消息
