Web Services are used for managing communication between an OEM application and Yellowfin. These are XML based and independent of the programming language used to develop the OEM application.

The web service interface Yellowfin exposes use SOAP, which is a protocol widely used for web services. Yellowfin provides a Java Web Service API for connecting to the SOAP web services, but it is also possible to connect from practically any other programming language or environment such as .NET, Ruby and Python.

Enabling Web Services                                 

You need to have a Yellowfin user with rights to perform web services calls. Ensure that this is turned on in the user role:

You will need the web services admin user's details (login name and password) to perform web service calls.


Java API

The Yellowfin Web Service API contains pre-generated stubs. This can be used directly in applications that are developed in Java, or other languages that support Java integration, such as Cold Fusion or Lotus Script. This makes integration slightly simpler as each request is not required to be manually generated, since most of the Web Services are wrapped by a standard Java function.


API can be called internally under Yellowfin Tomcat using JSP. The code samples can be found in the yellowfin/development/examples/webservices folder, once Yellowfin is installed. All you need to do is to copy the JSP files into the Yellowfin/appserver/webapps/ROOT folder and adjust the host, port number, and user details in the JSP files according to your environment. We recommend ensuring that you can achieve what you want using this method prior to replicating this with other languages or environments.


To call web services externally, you will need:


A full objects’ definitions can be found at Yellowfin/development/doc/webservices/Javadoc/index.html

There are two ways of calling Java API:

The code samples regarding this method can be found in the development/examples/webservices folder. See the jsp files with ‘api’ in their names. A good starting point is copying files with ‘mobile’ in their names, into the Yellowfin ROOT folder and explore.



All the code samples under Administration Service and Report Service sections are explained using SOAP calls in Java.


To initialize Administration service:

AdministrationServiceService s_adm = new AdministrationServiceServiceLocator(<host>,<port>, <ServicePath>, <ssl>) ;        

AdministrationServiceSoapBindingStub rssbs_admin = (AdministrationServiceSoapBindingStub) s_adm.getAdminService();


To initialize Report service:

ReportServiceService s_rpt = new ReportServiceServiceLocator(<host>, <port>, <ServicePath>, <ssl>);

ReportServiceSoapBindingStub rssbs_report = (ReportServiceSoapBindingStub) s_rpt.getReportService();








Yellowfin server



http port number to access Yellowfin server



Path to the service

Administration service path: "/services/AdministartionService"

Report service path: "/services/ReportService"



If SSL enabled: true


The primary objects include:

  • AdministrationServiceRequest: An object that defines the type of call being made to the web service.
  • AdministrationServiceResponse: An object returned by the web service.



There are two groups of web services:


Languages other than Java  

When developing against Yellowfin Web Services, it is possible to generate functional stubs against the WSDL definitions. These definitions can be found at http://<yellowfin-server>:<port>/services, for instance, http://localhost:8080/services.

The functional stubs will allow developers to make standard function calls in their native programming language which will directly communicate with the Web Services provided by Yellowfin. The process of creating function stubs should also generate any objects required by the webservice.



With .NET, we recommend generating stubs from JAX web services. You should be able to hit the JAX web services at: http://<yellowfin-host>/webservices/Hello. It will display something like this:

Connect your clients to the listed WSDL URLs.


There may be issues where data types between Java and .Net are not compatible. For example, Integer types that send through zero, rather than null. You might need to manually change the References.cs file to update the datatypes.




You can use Axis generated WSDL (http://<yellowfin-server>:<port>/services) with PHP. See examples of performing SSO using PHP.
