最近用client 向 IS判断access token是否合法，在使用编写代码测试时，发现OAuth2TokenValidationServiceStub.validate()一直失败。

代码如下：

 OAuth2TokenValidationServiceStub stub = null;
	String serviceURL = OAuth2ClientServlet.serverUrl + "OAuth2TokenValidationService";
	try {
	stub = new OAuth2TokenValidationServiceStub(null, serviceURL);
	} catch (AxisFault e) {
	// TODO Auto-generated catch block
	e.printStackTrace();
	}
	CarbonUtils.setBasicAccessSecurityHeaders(OAuth2ClientServlet.userName, OAuth2ClientServlet.password, true, stub._getServiceClient());
	ServiceClient client = stub._getServiceClient();
	Options options = client.getOptions();
	options.setTimeOutInMilliSeconds(TIMEOUT_IN_MILLIS);
	options.setProperty(HTTPConstants.SO_TIMEOUT, TIMEOUT_IN_MILLIS);
	options.setProperty(HTTPConstants.CONNECTION_TIMEOUT, TIMEOUT_IN_MILLIS);
	options.setCallTransportCleanup(true);
	options.setManageSession(true);
	
	OAuth2TokenValidationRequestDTO oauthReq = new OAuth2TokenValidationRequestDTO();
	oauthReq.setAccessToken(accessToken);
	oauthReq.setTokenType("bearer");
	
	try {

	bool resp = stub.validate(params);
	} catch (RemoteException e) {
	// TODO Auto-generated catch block
	e.printStackTrace();
	}
	
	

I faced the same problem with OAuth Mediator in Wso2 ESB 4.8.0 accessing Wso2 Identity Server 4.6.0 via Oauth2 validation web service. With Identity server 4.5.0 it works fine.The mediator code invokes the client stub passing the accessToken as plain string.

The error message returned by validation service is Access token identifier is not present in the validation request.

To answer your question you should use the bundle org.wso2.carbon.identity.oauth.stub in version 4.2.2. It defines a class org.wso2.carbon.identity.oauth2.stub.dto.OAuth2TokenValidationRequestDTO_OAuth2AccessToken which should be used as a parameter for the OAuth2TokenValidationRequestDTO.setAccessToken method. The dto object can the be used as parameter for the OAuth2TokenValidationServiceStub.validate method.

居然是版本问题！

 OAuth2TokenValidationRequestDTO oauthReq = new OAuth2TokenValidationRequestDTO();
OAuth2TokenValidationRequestDTO_OAuth2AccessToken oauthReq_token 
	= new OAuth2TokenValidationRequestDTO_OAuth2AccessToken();

oauthReq_token.setTokenType("bearer");
oauthReq_token.setIdentifier(accessToken);
oauthReq.setAccessToken(oauthReq_token);
