Are there any online resources which show the basic steps to access the Microsoft CRM on-premise web service with a client written in Java?
Which web service toolkit should I use?
I tried it with JAXB but there is a conflict in the WSDL element naming which requires a class customization. If I find the correct binding fix, I will post it here.
The Microsoft Dynamics CRM application on premise version uses Active Directory authentication. Although I never tried referencing the Microsoft Dynamics CRM web services from Java, I am sure it is feasible, as these are standard web services and therefor can be referenced from Java via SOAP, just like any other web service.
public class TestCRM {
private static String endpointURL = "http://server:port/MSCrmServices/2007/CrmService.asmx";
private static String userName = "username";
private static String password = "password";
private static String host = "server";
private static int portport = port;
//To make sure you are using the correct domain open ie and try to reach the service. The same domain you entered there is needed here
private static String domain = "DOMAIN";
private static String orgName = "THIS_IS_REQUIRED"; //this does the work....
public static void main(String[] args) {
CrmServiceStub stub;
try {
stub = new CrmServiceStub(endpointURL);
setOptions(stub._getServiceClient().getOptions());
RetrieveMultipleDocument rmd = RetrieveMultipleDocument.Factory.newInstance();
RetrieveMultiple rm = RetrieveMultiple.Factory.newInstance();
QueryExpression query = QueryExpression.Factory.newInstance();
query.setColumnSet(AllColumns.Factory.newInstance());
query.setEntityName(EntityName.######.toString());
//query.setFilter...
rm.setQuery(query);
rmd.setRetrieveMultiple(rm);
//Now this is required. Without it all i got was 401s errors
CrmAuthenticationTokenDocument catd = CrmAuthenticationTokenDocument.Factory.newInstance();
CrmAuthenticationToken token = CrmAuthenticationToken.Factory.newInstance();
token.setAuthenticationType(0);
token.setOrganizationName(orgName);
catd.setCrmAuthenticationToken(token);
boolean fetchNext = true;
while(fetchNext){
RetrieveMultipleResponseDocument rmrd = stub.RetrieveMultiple(rmd, catd, null, null);
RetrieveMultipleResponse rmr = rmrd.getRetrieveMultipleResponse();
BusinessEntityCollection bec = rmr.getRetrieveMultipleResult();
String pagingCookie = bec.getPagingCookie();
fetchNext = bec.getMoreRecords();
ArrayOfBusinessEntity aobe = bec.getBusinessEntities();
BusinessEntity[] myEntitiesAtLast = aobe.getBusinessEntityArray();
for(int i=0; i<myEntitiesAtLast.length; i++){
//cast to whatever you asked for...
### myEntity = (###) myEntitiesAtLast[i];
}
}
}
catch (Exception e) {
e.printStackTrace();
}
}
private static void setOptions(Options options){
HttpTransportProperties.Authenticator auth = new HttpTransportProperties.Authenticator();
List authSchemes = new ArrayList();
authSchemes.add(HttpTransportProperties.Authenticator.NTLM);
auth.setAuthSchemes(authSchemes);
auth.setUsername(userName);
auth.setPassword(password);
auth.setHost(host);
auth.setPort(port);
auth.setDomain(domain);
auth.setPreemptiveAuthentication(false); //it doesnt matter...
options.setProperty(HTTPConstants.AUTHENTICATE, auth);
options.setProperty(HTTPConstants.REUSE_HTTP_CLIENT, "true"); //i think this is good.. not required though
}
Java -> SOAP -> MS CRM 2011 Online : http://zsvoboda.blogspot.com/2011/03/connecting-to-microsoft-crm-2011-online.html
The stub has been created with the Apache Axis2 framework.
You can find resources here. You can even work with an example is available in Dynamics CRM SDK. As Manuel Freiholz said, you have to use Axis2.

Alternatively, you can use RESTFul web services through the OData interface offered by Dynamics (https://msdn.microsoft.com/en-us/library/gg334279.aspx)
