ReportReport
Posted on by Community Member

Hello All,

I am new to ms dynamics. What i am trying to do is consume REST and SOAP API's using Java but fail to do so.

The error that i get for REST API's with this code https://code.msdn.microsoft.com/Consuming-CRM-REST-Service-ae24a15e#content  is , it does not generate the classes it is supposed to and gives the following error.

org.apache.olingo.odata2.api.ep.EntityProviderException: javax.xml.stream.XMLStreamException: ParseError at [row,col]:[81,5]
Message: The declaration for the entity "ContentType" must end with '>'.

Can we not consuming services if i am on a trial account. Or where am i going wrong. 

Thank you

    Hi

    For CRM 2011, it is not possible to call the oData endpoint from an external application.

    you need user SOAP end point,

    For example, refer to article below:

    msdn.microsoft.com/.../jj602979(v=crm.5).aspx

    Hope this help!

    If you're satisfied with my answer, please mark it as verified.

    Hello thank you for your response.

    I have created a trial account for MSdynamics. When I generate the REST point from Developer Resources option it gives me link for 2011 i.e https://<server>.crm5.dynamics.com/XRMServices/2011/OrganizationData.svc/

    How can i change this.

    Next i have tried the article which you suggested.It generates all the files but again i am using 2011 SOAP API's. This fails as well and gives me an error :

    [ERROR] IDiscoveryService_Execute_DiscoveryServiceFaultFault_FaultMessage

    Exception in thread "main" java2crmpack.IDiscoveryService_Execute_DiscoveryServiceFaultFault_FaultMessage: IDiscoveryService_Execute_DiscoveryServiceFaultFault_FaultMessage

    Thank you for the link. This lets me connect to CRM and displays my name as well... but no luck in creating and retrieving accounts.

    Hi,

    Try generate queries using SOAP Logger application, it allows you to write your queries in Visual Studio using QueryExpression and capture the format of the fetch.

    refer this:

    Hope this help!

    Hi ,

    I tried this works well, generates the soap request and also works when i execute it using C#. When i try to execute the same using java gives me error status code 500. I am using the following code, SOAP is generated using C#. when i use the same url it authenticates me. only does not perform CRUD operations

    public static String Create(CrmAuthenticationHeader authHeader, String id, String url) throws IOException, SAXException,ParserConfigurationException
    {
    StringBuilder requestMain = new StringBuilder();

    requestMain.append("<s:Body>");
    requestMain.append("<Create xmlns=\"http://schemas.microsoft.com/xrm/2011/Contracts/Services\" xmlns:i=\"http://www.w3.org/2001/XMLSchema-instance\">");
    requestMain.append("<entity xmlns:a=\"http://schemas.microsoft.com/xrm/2011/Contracts\">");
    requestMain.append("<a:Attributes xmlns:b=\"http://schemas.datacontract.org/2004/07/System.Collections.Generic\">");
    requestMain.append("<a:KeyValuePairOfstringanyType>");
    requestMain.append("<a:Id>" + id + "</a:Id>");
    requestMain.append("<a:LogicalName>systemuser</a:LogicalName>");
    requestMain.append("<a:Name i:nil=\"true\" />");
    requestMain.append("<b:key>firstname</b:key>");
    requestMain.append("<b:value i:type=\"c:string\" xmlns:c=\"http://www.w3.org/2001/XMLSchema\">Neha</b:value>");
    requestMain.append("</a:KeyValuePairOfstringanyType>");
    requestMain.append("<a:KeyValuePairOfstringanyType>");
    requestMain.append("<b:key>lastname</b:key>");
    requestMain.append("<b:value i:type=\"c:string\" xmlns:c=\"http://www.w3.org/2001/XMLSchema\">Glynn</b:value>");
    requestMain.append("</a:KeyValuePairOfstringanyType>");
    requestMain.append("</a:Attributes>");
    requestMain.append("<a:EntityState i:nil=\"true\" />");
    requestMain.append("<a:FormattedValues xmlns:b=\"http://schemas.datacontract.org/2004/07/System.Collections.Generic\" />");
    requestMain.append("<a:Id>00000000-0000-0000-0000-000000000000</a:Id>");
    requestMain.append("<a:LogicalName>contact</a:LogicalName>");
    requestMain.append("<a:RelatedEntities xmlns:b=\"http://schemas.datacontract.org/2004/07/System.Collections.Generic\" />");
    requestMain.append("</entity>");
    requestMain.append("</Create>");
    requestMain.append("</s:Body>");

    Document xDoc = CrmExecuteSoap.ExecuteSoapRequest(authHeader,requestMain.toString(), url);

    System.out.println("xDoc"+xDoc);

    }
