通过客户端存根访问WSDL时Java InaccessibleWSDLException
我正在尝试为Exchange Web服务编写自定义Java客户端。 我已经使用wsimport工具生成了客户端存根，如EWS的Services.wsdl文件中所述。 现在我编写了使用这些存根的代码。 我得到以下exception：
Exception in thread "main" com.sun.xml.internal.ws.wsdl.parser.InaccessibleWSDLException: 2 counts of InaccessibleWSDLException. java.io.IOException: Got Server returned HTTP response code: 401 for URL: https://host.domain.com/ews/Services.wsdl while opening stream from https://host.domain.com/ews/Services.wsdl java.io.IOException: Got Server returned HTTP response code: 401 for URL: https://host.domain.com/ews/Services.wsdl?wsdl while opening stream from https://host.domain.com/ews/Services.wsdl?wsdl at com.sun.xml.internal.ws.wsdl.parser.RuntimeWSDLParser.tryWithMex(Unknown Source) at com.sun.xml.internal.ws.wsdl.parser.RuntimeWSDLParser.parse(Unknown Source) at com.sun.xml.internal.ws.wsdl.parser.RuntimeWSDLParser.parse(Unknown Source) at com.sun.xml.internal.ws.client.WSServiceDelegate.parseWSDL(Unknown Source) at com.sun.xml.internal.ws.client.WSServiceDelegate.(Unknown Source) at com.sun.xml.internal.ws.client.WSServiceDelegate.(Unknown Source) at com.sun.xml.internal.ws.spi.ProviderImpl.createServiceDelegate(Unknown Source) at javax.xml.ws.Service.(Unknown Source) at com.microsoft.schemas.exchange.services._2006.messages.ExchangeWebService.(ExchangeWebService.java:58) at com.xyz.abc.EWSJavaAPI.ExchangeAuthenticator.getExchangeServicePort(ExchangeAuthenticator.java:33) at com.xyz.abc.test.ExchangeDevelopmentTest.main(ExchangeDevelopmentTest.java:35)
正如我们在上面看到的， ExchangeDevelopmentTest是一个使用另一个类ExchangeAuthenticator的客户端，后者又使用生成的客户端存根ExchangeWebService 。 但是在堆栈跟踪中我得到了来自Unknown Sources的错误，可能是JDK的JAR。
IOException表示它有HTTP response code: 401 ，用于未经授权的访问。 但我已正确指定了用户名和密码，并且还在密钥库中包含了所需的证书。 这个exception的来源，我完全没有方向性。
我写的类的代码：
ExchangeAuthenticator
public class ExchangeAuthenticator { /** * Obtains an authenticated ExchangeServicePortType with given credentials. * */ public ExchangeServicePortType getExchangeServicePort(String username, String password, String domain, URL wsdlURL) throws MalformedURLException { // Concatinate our domain and username for the UID needed in authentication. String uid = "domain" + "\\" + "uname"; // Create an ExchangeWebService object that uses the supplied WSDL file, wsdlURL. ExchangeWebService exchangeWebService = new ExchangeWebService(wsdlURL, new QName("http://schemas.microsoft.com/exchange/services/2006/messages", "ExchangeWebService")); ExchangeServicePortType port = exchangeWebService.getExchangeWebPort(); // Supply your username and password when the ExchangeServicePortType is used for binding in the SOAP request. ((BindingProvider)port).getRequestContext().put(BindingProvider.USERNAME_PROPERTY, uid); ((BindingProvider)port).getRequestContext().put(BindingProvider.PASSWORD_PROPERTY, password); return port; } }
ExchangeDevelopmentTest
public class ExchangeDevelopmentTest { public static void main (String[] args) { ExchangeAuthenticator exchangeAuthenticator = new ExchangeAuthenticator(); // Print statement so we can easily see where our statements start in the Java console. System.out.println("Let's get started!"); try { // Create a URL object which points at the .wsdl we deployed in the previous step. URL wsdlURL = new URL("https://172.17.245.196/ews/Services.wsdl"); //URL wsdlURL = new URL("https://172.17.245.196/ews/Services.wsdl"); // Call to the class we just created to return an ExchangeServicePortType with authentication credentials. ExchangeServicePortType port = exchangeAuthenticator.getExchangeServicePort("uname", "password@123", "domain", wsdlURL); // Prints out the default toString() for the ExchangeServicePortType. System.out.println(port.toString()); } catch (MalformedURLException ex) { // Catch any errors that may occur. Logger.getLogger(ExchangeDevelopmentTest.class.getName()).log(Level.SEVERE, null, ex); System.out.println(ex.getMessage()+"\n"+ex.getStackTrace()); } } }
ExchangeWebService
由JAX-WS使用wsimport工具生成，删除了其他构造函数和方法。 只保留第58行调用super （此处为Service类）构造函数的构造函数。
@WebServiceClient(name = "ExchangeWebService", targetNamespace = "http://schemas.microsoft.com/exchange/services/2006/messages", wsdlLocation = "file:/C:/Services.wsdl") public class ExchangeWebService extends Service { private final static URL EXCHANGEWEBSERVICE_WSDL_LOCATION; private final static WebServiceException EXCHANGEWEBSERVICE_EXCEPTION; private final static QName EXCHANGEWEBSERVICE_QNAME = new QName("http://schemas.microsoft.com/exchange/services/2006/messages", "ExchangeWebService"); static { URL url = null; WebServiceException e = null; try { url = new URL("file:/C:/workspace/Server%20files/Client%20files/Services.wsdl"); } catch (MalformedURLException ex) { e = new WebServiceException(ex); } EXCHANGEWEBSERVICE_WSDL_LOCATION = url; EXCHANGEWEBSERVICE_EXCEPTION = e; } //other constructos & methods removed //line 58 public ExchangeWebService(URL wsdlLocation, QName serviceName) { super(wsdlLocation, serviceName); } }
为什么在可以拥有本地副本时访问远程WSDL文档文件（和模式文件）？ 当然，访问端点仍然需要安全性。
首先，您需要根据环境添加类加载器。
// Java EE Enviroment ClassLoader cl = Thread.currentThread().getContextClassLoader(); // Java Standalone Enviroment ClassLoader cl = ClassLoader.getSystemClassLoader();
接下来，在项目中本地存储WSDL文档文件的副本（以及方案文件，如果需要）。
URL wsdlLocation = cl.getResource("com/mahesha999/ExchangeWebService.wsdl"); QName qName = new QName( "http://schemas.microsoft.com/exchange/services/2006/messages", "ExchangeWebService" ); ExchangeWebService exchangeWebService = new ExchangeWebService(wsdlLocation, qName); ExchangeServicePortType port = exchangeWebService.getExchangeWebPort();
如果需要身份validation来访问Web服务端点，则最基本的forms如下：
BindingProvider provider = (BindingProvider) port; Map context = provider.getRequestContext(); context.put(BindingProvider.USERNAME_PROPERTY, username); context.put(BindingProvider.PASSWORD_PROPERTY, password);
如果您需要处理证书等问题，最好先看看Securing WebLogic Web Services 。
你这样添加用户名和密码了吗？
ShopingCart sc = scs.getShopingCartPort(); Map requestContext = ((BindingProvider)sc).getRequestContext(); requestContext.put(BindingProvider.USERNAME_PROPERTY, userName); requestContext.put(BindingProvider.PASSWORD_PROPERTY, password);
您尚未提供有问题的客户代码。 你在使用代理吗？ 然后你必须在上面提供你的代理用户名和密码。
