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,如下所述这里。现在我编写了使用这些存根的代码。我得到以下异常:
I am trying to write custom Java client for Exchange Web Services. I have generated client stubs using wsimport tool as explained here from EWS's Services.wsdl file. And now I have written code that uses these stubs. I am getting following 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: host.domain/ews/Services.wsdl while opening stream from host.domain/ews/Services.wsdl java.io.IOException: Got Server returned HTTP response code: 401 for URL: host.domain/ews/Services.wsdl?wsdl while opening stream from host.domain/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.<init>(Unknown Source) at com.sun.xml.internal.ws.client.WSServiceDelegate.<init>(Unknown Source) at com.sun.xml.internal.ws.spi.ProviderImpl.createServiceDelegate(Unknown Source) at javax.xml.ws.Service.<init>(Unknown Source) at com.microsoft.schemas.exchange.services._2006.messages.ExchangeWebService.<init>(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那样 ExchangeDevelopmentTest 是一个客户端使用另一个类 ExchangeAuthenticator ,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,大概是JDK的JAR。
As we can see above ExchangeDevelopmentTest is a client that uses another class ExchangeAuthenticator which in turn uses generated client stub ExchangeWebService. But up in the stack trace I got errors from Unknown Sources presumably JDKs' JARs.
IOException 说得到了 HTTP响应代码: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。这个异常的来源,我完全没有方向性。
The IOException says it got HTTP response code: 401, that is for unauthorized access. But I have correctly specified the user name and password and also have included the needed certificate in the keystore. I am totally directionless where this exception is coming from.
我写的课程代码:
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("<a href=\"schemas.microsoft/exchange/services/2006/messages\">schemas.microsoft/exchange/services/2006/messages</a>", "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("172.17.245.196/ews/Services.wsdl"); //URL wsdlURL = new URL("<a href=\"172.17.245.196/ews/Services.wsdl\">172.17.245.196/ews/Services.wsdl</a>"); // 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行中调用 super (此处为 Service class)构造函数的构造函数。
Generated by JAX-WS with wsimport tool, other constructors and methods removed. Only contructor at line 58 which calls super (here Service class) constructor is kept.
@WebServiceClient(name = "ExchangeWebService", targetNamespace = "schemas.microsoft/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("schemas.microsoft/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); } }推荐答案
为什么在您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。
Why access the remote WSDL document file (and schema files) when you can have a local copy? Of course, security is still required to access the endpoint.
首先,您需要根据环境加载类。
First, you need the class loader according to the environment.
// Java EE Enviroment ClassLoader cl = Thread.currentThread().getContextClassLoader(); // Java Standalone Enviroment ClassLoader cl = ClassLoader.getSystemClassLoader();接下来,在您的本地存储WSDL文档文件的副本(以及方案文件,如果需要)项目。
Next, store locally a copy of the WSDL document file (and the scheme files if needed) in your project.
URL wsdlLocation = cl.getResource("com/mahesha999/ExchangeWebService.wsdl"); QName qName = new QName( "schemas.microsoft/exchange/services/2006/messages", "ExchangeWebService" ); ExchangeWebService exchangeWebService = new ExchangeWebService(wsdlLocation, qName); ExchangeServicePortType port = exchangeWebService.getExchangeWebPort();如果需要身份验证来访问Web服务端点,则最基本的形式如下:
If authentication is required to access the webservice endpoint, in its most basic form, is as follows:
BindingProvider provider = (BindingProvider) port; Map<String, Object> context = provider.getRequestContext(); context.put(BindingProvider.USERNAME_PROPERTY, username); context.put(BindingProvider.PASSWORD_PROPERTY, password);如果你需要处理证书等等,最好看看 保护WebLogic Web服务 。
If you need to deal with certificates and that sort of thing, better have a look at Securing WebLogic Web Services.
