java - 来自 Java 的 Dynamics CRM 2011 在线 Web 服务

Question

我正在尝试从 Java 访问 MicroSoft Dynamic CRM 2011 在线 Web 服务，但到目前为止还没有成功。

我在 Axis2 (wsdl2Java) 的帮助下获得了组织 WSDL 文件并生成了所需的 java stub 文件。

我的简单客户端代码是

public class TestCRM2 {

public static void main(String[] args) {

    try {   

        // create query
        QueryExpression query = new QueryExpression();
        query.setEntityName("Contact");

        ArrayOfstring colAra = new ArrayOfstring();
        colAra.addString("fullname");

        ColumnSet columnSet = new ColumnSet();
        columnSet.setAllColumns(false);
        columnSet.setColumns(colAra);

        PagingInfo pageinfo = new PagingInfo();
        pageinfo.setCount(10);
        pageinfo.setPageNumber(1);

        query.setColumnSet(columnSet);
        query.setPageInfo(pageinfo);            

        ConditionExpression condition = new ConditionExpression();
        condition.setAttributeName("fullname");
        condition.setOperator(ConditionOperator.Equal);

        ArrayOfanyType values = new ArrayOfanyType();
        values.setAnyType(new String[] {"something"});
        condition.setValues(values);

        RetrieveMultiple retrieveMultiple = new RetrieveMultiple();
        retrieveMultiple.setQuery(query);

        OrganizationServiceStub stub = new OrganizationServiceStub();           

        //set Timeout 
        ServiceClient serviceClient =  stub._getServiceClient();
        serviceClient.getOptions().setTimeOutInMilliSeconds( 3 * 60 * 1000);
        /*serviceClient.getOptions().setProperty(HTTPConstants.HTTP_PROTOCOL_VERSION, HTTPConstants.HEADER_PROTOCOL_10);
        serviceClient.getOptions().setProperty(HTTPConstants.HEADER_TRANSFER_ENCODING_CHUNKED,false);*/         

        RetrieveMultipleResponse response = stub.retrieveMultiple(retrieveMultiple);            

        EntityCollection collection = response.getRetrieveMultipleResult();
        int count = collection.getTotalRecordCount();
        System.out.println(count);      

    } catch (Exception e) {
        e.printStackTrace();
    }
}}

当我从 Eclipse 运行此程序时，出现以下运行时错误

我的客户端代码中是否缺少任何内容？非常感谢您的帮助。

问候，

Answer 1

1. 您必须在服务客户端中的端点 URL 末尾附加“/web”。
2. 您必须提供 NTLM2 身份 validator 实现，并将其注册到您的 stub 使用的 httpclient。
