在这里，我正在尝试阅读共享点列表。为此，我做了以下工作:
我已经下载了从 URL 获得的 WSDL 文件，例如:sharepointsite.com/_vti_bin/Lists.asmx?WSDL。
我已经执行了以下命令来生成目录中的类
“C:\Program Files\Java\jdk1.6.0_12\bin\wsimport.exe” -p com.microsoft.schemas.sharepoint.soap -keep -extension Lists.wsdl。
在我的 eclipse IDE java 应用程序中导入了这些类。
我写了以下代码
/* 创建一个连接到给定 SharePoint Web 服务的端口。
* Authentication is done here. It also prints the authentication details
* in the console.
* @param userName SharePoint username
* @param password SharePoint password
* @return port ListsSoap port, connected with SharePoint
* @throws Exception in case of invalid parameters or connection error.
*/

port = service.getListsSoap();
System.out.println("Web Service Auth Username: " + userName);
((BindingProvider) port).getRequestContext().put(BindingProvider.USERNAME_PROPERTY, userName);
((BindingProvider) port).getRequestContext().put(BindingProvider.PASSWORD_PROPERTY, password);
} catch (Exception e) {
throw new Exception("Error: " + e.toString());
}
} else {
throw new Exception("Couldn't authenticate: Invalid connection details given.");
}
return port;
}

我收到以下异常:
Web 服务身份验证用户名:“域\用户名”
java.lang.Exception:异常。请参见 stacktrace.javax.xml.ws.soap.SOAPFaultException:抛出了“Microsoft.SharePoint.SoapServer.SoapServerException”类型的异常。
It would be helpfull if i get the specific exception from the server.With this expection i am unable to track my pgm.
I dont know where did i go wrong? am i missing anything ? any configuration is required ?
Thanks in advance for your help
最佳答案
我遇到了同样的问题，尝试使用 Authenticator :
new BasicAuthentication(userName,password).authenticate();
我的 BasicAuthentication 类:
import java.net.Authenticator;
import java.net.PasswordAuthentication;
public class BasicAuthentication extends Authenticator
{
private String username;
private String password;
public BasicAuthentication(String username, String password)
{
this.username = username;
this.password = password;
}
public PasswordAuthentication getPasswordAuthentication()
{
return (new PasswordAuthentication(username,password.toCharArray()));
}
public void authenticate()
{
Authenticator.setDefault(this);
}
}
