Overview
Overview
This section discusses both how an administrator can configure Data Services
through the Administrator to publish Data Services jobs as callable web
services, and how an application developer can access those web services.
Data Services publishes web services from the Data Services Management
Console Administrator. To use Data Services as a web service, select the
Web Services node in the Administrator's navigation tree. For general
information on using the Administrator, see the Data Services Management
Console: Administrator Guide.
Web services are modular business applications based on open standards
(WSDL, SOAP, and XML Schema primarily) that allow integration among
different applications and environments through the Internet. Web services
allow parts of existing applications to be used by other applications.
For business intelligence (BI), you can use Web services to accomplish the
following:
• Access legacy systems
• Conduct computer-to-computer interaction over an internal or external
Web
• Allow applications constructed in different languages on different platforms
to communicate with each other in an enterprise environment
BusinessObjects Data Services can:
• Publish any job as a callable web service (server functionality)
• Call published web services from within its jobs using the built-in Web
Services Adapter (client functionality)
If you have an application that also supports web services, you can use that
application to run Data Services batch and real-time jobs or to publish your
application's functionality to be called by Data Services data flows.
After you install Data Services, you can immediately start working with its
client functionality because the built-in Web Services Adapter is a web
services client that provides access to a web services server from a Data
Services data flow.

Web services technologies
Data Services web services are fully compliant with Web Services
Interoperabilty (WS-I) Basic Profile 1.0, and support three Java Web Services
technologies.
DescriptionWeb service tech-

SOAP
WSDL
Data Services supports SOAP 1.1, WSDL version 1.1 or 2.0, and Apache
Axis 1.1 (an industry-standard SOAP message handler and WSDL parser).
Data Services is also compliant with the Microsoft .NET environment for Web
services. You can import the WSDL that Data Services generates into Visual
Studio .NET and the Data Services Web Services Adapter can call the WSDL
that Visual Studio .Net generates.
Note:
Data Services does not support the Representational State Transfer (REST)
web services architecture or the JSON message format.
Data Services allows you to invoke real-time services using the following:
• Message Client API (which supports C++ and Java connections)
• TCP/IP
• proprietary XML using HTTP
Language used to request a service and return replies
(subset of XML)
Format used for the WSDL fileXML Schema
In addition, Data Services supports the Simple Object Access Protocol
(SOAP). SOAP is the industry standard from the World Wide Web Consortium
(WC3.org) used to invoke network resources using XML over HTTP, HTTPS,
and other standard protocols.
Data Services Integrator's Guide 17
Web service support

Web services technologies
WSDL
A SOAP gateway is built in to the Data Services Administrator. Data Services
supports SOAP over HTTP and HTTPS protocols.
Web Services Description Language (WSDL) is a subset of XML. It is used
as a transport mechanism for XML messages. Data Services publishes its
jobs in WSDL based on configuration settings applied in the Administrator,
and then developers can create a web services client based on the Data
Services WSDL.
Data Services also publishes all comments entered into the Designer's Job
Descriptions box with each job that is added to the WSDL file.
The WSDL file generated by Data Services includes tags (such as services,
bindings, ports, and operations) that support the use of the SOAP protocol.
Each tag uses a name that Data Services provides. For example:
• You select which Data Services jobs to publish in the web service named
DataServices_server. In WSDL, a service is a set of business operations
with connection endpoints.
• Binding names include Connection_Operations, Batch_Jobs, Real-
time_Services, and Batch_Job_Admin. WSDL uses bindings to associate
operations with ports.
• Operation names have a one-to-one relationship with the names of Data
Services batch jobs or real-time services.
XML Schema
WSDL uses XML Schemas to define input and output message formats.
• For server functionality, if a real-time service was defined with DTDs, you
will need to translate the DTD format into the XML Schema format.
• For client functionality, the Web Services Adapter imports metadata into
Data Services using the XML Schema format only.
XML Schema formats are defined in the types element of the WSDL file.
18 Data Services Integrator's Guide
UDDI
Web service support
Web services technologies
UDDI is a method of publishing comments and other reference information
about jobs to an external web site. Data Services does not publish information
to a UDDI web site because most Data Services web services users work
behind enterprise firewalls.

Using Data Services as a web service provider

WSDL basics
After the Administrator publishes batch or real-time jobs as web services,
the web application hosts those web services. When an external application
calls into Data Services through web services, the application acts as a web
services client accessing a web services server.
Web service clients call the published web services, pass in the appropriate
parameters, and receive the results. Data Services routes calls to the
appropriate Data Services Job Server and job for processing.
Web services might be used in the following example scenarios:
• Dynamically update an internal web site
Suppose you have an internal web site that manages foreign exchange
rate status worldwide for the Finance department. When foreign exchange
rates change more than a certain percentage, a batch Data Services job
updates exchange rates in your financial data mart. The rate change
initiates a call to a Data Services-hosted Web service that starts the
appropriate batch ETL job.
• Solve a processing issue
Suppose you have an existing Enterprise Application Integration (EAI)
bus infrastructure and want to manage batch processes and EAI
transactional processes from within the same infrastructure. The
transactional processes are complex. Their staging is laid out in the order
process. However, EAI work flows do not have the ability to run batch
processes.
22 Data Services Integrator's Guide
Data Services can publish Web services that allow you to leverage EAI
process management category tools (for example, webMethods Business
Process Manager) to control and stage batch processes alongside its
transactional processes.
The work flows might call Data Services to:
• Perform an initial load of a data mart for real-time reporting
• Refresh the data cache depending on specified business criteria
• Perform complex transforms on hierarchical objects for mapping data
between ERP systems
WSDL basics
WSDL is a subset of XML that you can use to describe network services as
a collection of endpoints capable of exchanging messages.
This table shows the elements in a WSDL file, and describes how those
elements are used in the Data Services-generated WSDL file.

• Real-time_Services: used for real-time jobs
exposed as Web services
• Batch_Jobs: used for batch jobs exposed as Web
services (each batch jobs has its own operation)
• Batch_Job_Admin: used for administrative oper-
ations for batch jobs
Defines a set of operations that a Web service
publishes.
A portType is bound to a particular port. The binding
specifies the protocol and data formation for the
operations defined by a portType.

Building a WSDL file
Use the information in the WSDL file produced by Data Services to create
an application that can access Data Services batch jobs and real-time
services. Access the WSDL file by making web service client calls to it using
a reference URL.
To view the WSDL file so that you can create your application, use the Web
Services node of the Data Services Management Console Administrator,
or open a browser window and search for:
http://hostname:port/DataServices/servlet/webservices?ver=2.0&wsdlxml
To configure web service information using the Administrator
1. Open Data Services Administrator.
2. Log in with Administrator-level privileges. Users with Monitor-level
privileges cannot configure web services.
3
Note:
If you enable security for the WSDL file, Data Services requires that web
services clients use the user name and password of any user with
Administrator-level privileges to access all published web services.
3. Add connections from Access Servers and repositories to view jobs in
the Administrator.
4. If you plan to publish real-time jobs as web services, configure real-time
jobs as real-time services.
Data Services publishes the following as web services:
• Real-time services enabled as web service operations in the
Administrator
• Batch jobs enabled as web service operations in the Administrator
• Connection Operations
• Ping - Used to ping Web services
• Logon and Logout - Security operations that provide controlled
access to Web service operations (if enabled).
Data Services Integrator's Guide 25

WSDL basics
5. In the Administrator's navigation tree, select Web Services.
The "Web Services Status" page opens. This page lists Web service
operations that are published in the WSDL. By default, only the Ping
operation is automatically published.
6. Click the Web Services Configuration tab.
Use the Configuration tab to open the "Web Services Configuration"
page. Use this page to select jobs and real-time services to be published,
enable/disable security for the WSDL file, and to enable/disable access
to full batch job attributes.
7. From the pull-down menu, use Add Real-time Service or Add Batch
Job to add jobs or services to the WSDL, and click Apply.
On the "Add Real-time Service" page, real-time services are grouped by
the Access Server for which the service is configured. To add a real-time
service to the WSDL, select an Access Server or select All, select the
check box in front of a real-time service name, and click Add.
On the "Add Batch Job" page, jobs are grouped by the repository on
which the job is stored. To add a job to the WSDL, select a repository or
select All, select the check box in front of a job name, and click Add.
8. (Optional) On the "Web Services Configuration" page, select Enable
Session Securty and click Apply to enable security for the WSDL.
Security for published operations is disabled by default.
With security enabled, instead of making a single call to the Administrator
to start a batch job or trigger a real-time service from an external
application, clients must make at least three calls:
• The first call logs in to the Administrator and gets a session ID.
• The second call accesses a job or service using the session ID as an
input parameter. Create a call for each job or service you want to
access.
• The final call logs out of the session.
9. (Optional) On the "Web Services Configuration" page, from the drop-down
menu, select Enable Job Attributes to allow the input message for all
the batch jobs you publish to include all options supported for submitting
batch jobs from the Administrator. The following table lists elements added
to the message:

A new browser window opens with the WSDL displayed. Use the
information in this file to perform the following:
• Confirm that Data Services updated the WSDL file with all jobs and
services without error.
• Create calls to Data Services
3
Use the information in the WSDL file to configure your application to
access Data Services batch jobs and real-time services.
To ensure that your application calls the latest version of the job,
update the WSDL when the metadata imported into Data Services
changes for a job or real-time service by removing then re-adding a
job or service from the "Web Services Configuration" page.
11. After your web service clients are accessing Data Services jobs, you can
monitor the status of web service operations on the server by viewing the
data on the "Web Services Status" page.
