As organizations expand and technology evolves, application integration becomes increasingly important. Component reuse and interoperability requirements have driven companies to move toward a Service-Oriented Architecture (SOA), where self-contained business logic can be exposed and shared efficiently across applications and platforms. At the heart of recent success in SOA designs are Web services, a technology that enables disjoint applications to communicate with each other in a platform- and language-independent manner.

Specifically, a Web service is a self-contained piece of software available via standard network protocols—such as HTTP(S), FTP, and SMTP—and exposed by a standardized interface, the Web Service Description Language (WSDL). The WSDL is a schema-defined XML document that includes all of the information an application requires to call, or consume, the Web service. Data is exchanged between the application and the Web service, using a standard XML messaging format called Simple Object Access Protocol (SOAP).

Web services, like all technology, are rapidly evolving. Implementations range from basic Remote Procedure Calls (RPCs) to loosely coupled, document-style messaging. The WSDL and SOAP specifications are expanding to include support for secure, reliable, transactional Web services. Enhancements in these areas are helping to make Web services the preferred solution for application integration throughout the industry.

Basics

Historically, differences in platforms (Windows, UNIX, iSeries, etc.) and programming languages (Java, COBOL, C, etc.) have created complexities, making application integration difficult and costly. However, industry-wide standards for transport protocols, coupled with XML standards for Web services, have helped organizations spend considerably less time working out communication and messaging details, allowing them to focus on servicing their business requirements.

To help describe the various components of Web services, organizations in the industry have defined a technology stack. An example stack that demonstrates the relationships between various Web services standards is depicted in Figure 1.

Figure 1: This example Web services stack shows the relationship between the Web Services Standards. (Click images to enlarge.)

Transport

The Web services transport layer defines the communications protocol for exchanging data between Web services. As shown in Figure 1, it can use many different Internet transport protocols. Early adopters of SOAP 1.1, the initial Web service specifications controlled by the W3C (World Wide Web Consortium), assumed HTTP(S) for Web service transport. However, other protocols, such as SMTP, FTP, and IBM's MQSeries are increasingly being used and have been incorporated into the updated SOAP 1.2 specification.

Messaging

The Web services messaging layer uses the XML-based SOAP, which is described by the W3C as "a simple and lightweight mechanism for exchanging structured and typed information between peers in a decentralized, distributed environment using XML."

Figure 2: The SOAP message consists of three parts.

A SOAP message (Figure 2) is an XML document consisting of three parts: the envelope describing the message, the header describing the data types and rules, and the body containing the actual message. The following code example shows a basic SOAP message requesting the temperature for a particular ZIP code:



xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" 
xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" 

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 

xmlns:xsd="http://www.w3.org/2001/XMLSchema">
 
        
                 String
        
 


The platform-independent nature of XML allows applications to understand and decode the SOAP XML messages, regardless of the platform and programming language. For example, an application running on a UNIX platform using C++ is able to request the temperature using the above SOAP request from an application running on an iSeries using Java. The server-side application might respond with a SOAP message containing an appropriate response; an example message is shown below.



xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" 

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 

xmlns:xsd="http://www.w3.org/2001/XMLSchema">

Service Description

The Web Service Description Language (WSDL) is a standardized XML document that describes everything that an application requires to consume a Web service. It includes information such as the operations available, their corresponding interface (input and output parameters), the messaging format, and the transport protocol. As with the SOAP message, the fact that WSDL is described in a standard XML format makes it machine-readable and platform-independent. An example of a simple WSDL document describing the temperature Web service is below:


xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"
xmlns="http://schemas.xmlsoap.org/wsdl/" targetNamespace="http://www.xmethods.net/sd/TemperatureService.wsdl"
name="TemperatureService">
            
                          
            

            
                         
            

            
                          
                                         
                                         
                          

           

           
                                                transport="http://schemas.xmlsoap.org/soap/http"/>
                       
                                     
                                     
                                               

                                               encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"

                                               namespace="urn:xmethods-Temperature"/>
                                     
                                     
                                               

                                               encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"

                                               namespace="urn:xmethods-Temperature"/>

Publication (UDDI)

Universal Description, Discovery, and Integration (UDDI) is an XML-based standard for publishing, finding, and describing Web services over the Internet. The UDDI specification can be used to create a registry of Web services, similar to registries that exist for telephone numbers.

UDDI registries are used by clients wishing to discover and consume specific Web services and by clients wishing to publish their own Web services. Clients use SOAP messages to communicate with UDDI registries, which provide access to WSDL documents published by organizations.

Figure 3 describes the relationship between SOAP, WSDL, and UDDI.

Figure 3: This diagram describes the relationships among SOAP, WSDL, and UDDI.

SOAP Messaging in Detail

The WSDL specification allows for two distinct styles of messaging: document and RPC. With document-style messaging, the message details contained within the SOAP body element of the request and response are in the form of an XML document in a format agreed upon by the sender and receiver. In contrast, RPC-style messaging uses a specific XML representation of a procedure call to describe the message details.

The WSDL specification also allows for two methods of serializing the XML data contained within the SOAP body element: SOAP encoding and literal. Messages that use SOAP encoding serialize their data by conforming to the set of rules defined in the SOAP 1.1 specification, section 5. Literal messages are serialized according to an XML schema definition.

These two choices in Web service design—the messaging style and the method used to serialize the XML data—result in four basic styles of Web services available today. These are as shown in the table below.

Web Service Design Options

Document Style
RPC Style
SOAP Encoding
Document/encoded
RPC/encoded
Literal
Document/literal
RPC/literal

Of the four styles listed, the two most commonly used are RPC/encoded and document/literal. Both styles are examined in the following sections.

RPC/encoded

RPC/encoded was one of the first Web service styles supported by early versions of SOAP engines. SOAP engines are used to generate implementations of the SOAP protocol, which can include the transport layer and the creation and consumption of the WSDL and the corresponding SOAP messages. RPC/encoded is the simplest of encoding styles because it enables SOAP engines to serialize and de-serialize data and automatically bind data to the remote object of an RPC. All that is left for the developer to do is map the input and output parameters of the Web service. An RPC/encoded sample of a WSDL and corresponding SOAP request are presented in Appendix A.

The following excerpt taken from the WSDL section in Appendix A highlights the reference to the section of the WSDL that indicates the messaging style (binding style).

style="rpc" 

transport="http://schemas.xmlsoap.org/soap/http"/>

The code below references the section of the WSDL that indicates the encoding style (use).

                
                       

encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" 

namespace="http://soapserver.jsm.lansa.com"/>
                

The major strength of the RPC/encoded style is its ease of use for both the service provider and the service consumer. The WSDL resembles an intuitive RPC-type interface. RPC/encoded SOAP messages include the operation name, allowing them to be dispatched accordingly, as shown in the add operation in the following example:


        
                

However, RPC/encoded Web services do have some major drawbacks. First, the style is not compliant with WS-I. (The WS-I is an organization that governs standards for Web service interoperability.) A Web service is considered compliant with WS-I if it is written in accordance with these standards. This means that with RPC/encoded Web services, there is a possibility that clients on other platforms might not be able to properly use the Web service. The second drawback is that the message details and the Web service interface (WSDL) are tightly coupled. Any change to a particular parameter of a specific operation of the Web service requires changing and re-publishing the entire WSDL; thus, consumers of the Web service will have to re-build their client-side SOAP engine according to the revised WSDL.

Document/literal

The document/literal style of Web services is becoming more commonly used. It overcomes the two major issues with RPC/encoded Web services: 1) Document/literal Web services conform to the WS-I guidelines for interoperability, and 2) There is loose coupling between the message body and the WSDL. Because the message body is a normal XML document defined by a schema and is independent of the WSDL, changes to message parameters do not require a change to the WSDL. In this case, the client would be required to modify only the XML messages to match the new schema and would not have to adjust the SOAP engine.

Appendix B contains an example of a WSDL for a document/literal Web service. Notice that the WSDL binding style indicates a document style of messaging and a literal encoding.


transport="http://schemas.xmlsoap.org/soap/http"/>



       


One drawback to this style is that because an XML schema defines the message body (independent of the WSDL), the operation name in the SOAP message is lost. Without the operation name, it is difficult, if not impossible, for the SOAP engine to dispatch the message appropriately. This can be seen in the SOAP message request fragment below:


                
                        
                                 String
                                 String
                        
                        
                                 String
                                 String
                        
                        

                                 String
                                 String
                                 String
                        

                 
                 
                         String
                         String
                 

Notice that the body of the SOAP request contains two parameters, person and phone, but the operation name (add) is not reflected anywhere in the body of the message.

To overcome this limitation, many implementations are beginning to use the wrapped convention for document/literal-style messages. Wrapped document/literal messages are document/literal messages that follow two additional rules: 1) The body of the message contains only one element, and 2) That element has the same name as that of the operation being invoked. An example of this is presented in the code fragment below. The complete SOAP message is listed in Appendix B.


        
                
                        
                                 String
                                 String
                        
                        
                                 String
                                 String
                        
                        

                                 String
                                 String
                                 String
                        

                
                
                         String
                         String
                
        

The body of this SOAP request now contains one element, appropriately named after the "add" operation, which wraps the message parameters (person and phone). This allows SOAP engines to determine the invoked operation from the SOAP document and dispatch the message accordingly.

The only significant limitation to the wrapped document/literal style (also true for the non-wrapped document/literal style) is the inability to override operations within the Web service. This is because a Web service with overridden operations would require defining multiple elements with the same name, which is not allowed in the schema specification. This limitation does not exist for RPC/encoded Web services.

Which One to Use?

Wrapped document/literal Web services present many advantages that generally outweigh their limitations. As Web services and SOAP tools become more advanced, added complexity will become a non-factor. On one hand, RPC/encoded Web services allow for overriding operations and provide a straightforward interface to a pre-existing RPC. On the other hand, where flexibility and interoperability are key requirements, wrapped document/literal Web services are the most suitable and are the recommended approach moving forward.

The Evolution of Web Services

Web services are quickly becoming the method of choice for many organizations looking for interoperable application integration. And while the basic specifications have been mostly effective in this area, companies and individuals are looking to expand on them to allow for features such as increased security, reliable messaging, and support for transactions. As a result, organizations such as Microsoft and IBM have collaborated to create a set of specifications to meet these demands. These include specifications for security, transactions, and reliable messaging, which are discussed in more detail below.

Composability

To ensure that these new capabilities are not imposed and don't affect existing Web services solutions, the specifications have been designed using the principle of composability. This term describes the design concept in which individual services (or specifications) can be used as required. For example, one organization can choose to implement a Web service utilizing the security and reliable messaging specifications, while another may choose to implement transactions only. Each specification is completely optional and independent, allowing companies to implement only the specifications they require.

Figure 4 shows an updated Web services stack, which now includes specifications for security, transactions, and reliable messaging.

http://www.mcpressonline.com/articles/images/2002/Lalani%20State%20of%20the%20Art%20Web%20ServicesV4--03220603.jpg

Figure 4: An updated SOAP stack includes security, transactions, and reliable messaging.

Security
The basic Web services specifications allow for security to be handled at the transport level. Transport protocols can ensure that communication between two parties is secure. Therefore, Web services can take advantage of transport protocol implementations, such as HTTPS and FTPS to secure the communication link.

Sometimes, however, additional security is required at the application level. For example, it may be required that all or part of the SOAP message be encrypted to ensure that only the intended party is able to decrypt and view the contents. WS-Security enables this type of security. The specification utilizes existing security protocols such as Kerberos and X509 and defines how they are to be used in an interoperable manner.

Another security specification, WS-Trust, enables Web services to establish trusted relationships between applications. For example, an organization using Web services with WS-Trust is able to use a security token to validate the sender of a particular SOAP message.

The additional security specifications, including WS-Security and WS-Trust, can work in addition to transport-level security to help companies achieve the level of security that they require.

Transactions
Some business functions are difficult to implement because they require coordination between related business processes. For example, imagine a financial institution that provides a service allowing individuals to transfer money from one account to another. Such a service is actually made up of a number of smaller services, including services to check the source account balance, debit the source account, and credit the target account. These services need to be carried out within a transaction, i.e., they must be coordinated and performed in a particular sequence. A credit should not be applied to the target account before the balance of the source account is verified. These types of transactional business services would be difficult to implement using the basic specifications for Web services.

However, recent specifications are providing Web services with these transactional capabilities. WS-Coordination, for example, facilitates coordination between related services. It defines additional elements to be included within related SOAP messages and defines a coordinator service, which acts to coordinate and sequence the related operations. WS-AtomicTransaction and WS-BusinessActivity build on the WS-Coordination specification, adding support for atomic, all-or-nothing business transactions, with error and exception-handling capabilities.

Reliable Messaging
The inherently unreliable nature of application communication over the Internet forces companies to build reliable messaging techniques into their distributed applications. Until recently, organizations using Web services have had to employ techniques outside of the base Web services specifications to ensure that messages are exchanged reliably. These techniques are employed at the application level and require some negotiation on standards between business partners.

The WS-ReliableMessaging specification allows companies to enable reliable messaging from within the Web services stack, once again allowing applications to focus back on the business logic. The specification defines a protocol that ensures that messages are delivered in the correct order without duplication.

With Web Services, SOA Is Evolving

Organizations are evolving toward a Service-Oriented Architecture, enabling services to be shared across applications, networks, and platforms. Web services have helped to achieve this difficult task, employing XML standards that allow data exchange and application integration in a platform-independent manner. Wrapped document/literal-style messaging is providing for increased flexibility and interoperable Web services, where entire XML documents are exchanged containing the request and return parameters. In addition, emerging standards for security, transactions, and reliable messaging are enabling organizations to rely on Web services to help with creating state-of-the-art distributed, multi-platform applications, while allowing their focus to shift back to what they know best: their business.
