Web Service Framework comparison

Web Services is one of those concepts made all the more difficult to understand because of the myriad acronyms and abbreviations that are superfluous in any discussion. Covering all the concepts and standards associated with Web Services is a vast topic in itself. There are a large number of standards around Web Services. These standards define the norms of a Web Services implementation and ensure that a Web Services is accessed independently of the client platform. There are numerous frameworks available to select to build web service today. Below is the most widely used ones.

Does it fit my need?

Axis2.0

Apache Axis2 is a complete re-design and re-write of the widely used Apache Axis SOAP stack to build on the lessons learnt from Apache Axis.

An advantage of Axis 2 is its support for the binding frameworks XMLBeans. Axis 2 with XMLBeans is widely used for building Web Services solutions with very complex schema definitions.

The disadvantages of Axis 2 are its complexity and insufficient JAX-WS support.

There is also no integration support for Spring. Currently the only available Spring support in Axis2 is by embedding a Spring container inside a service archive (AAR), i.e. implementing an Axis2 service using Spring. However, what most people are looking for is to embed Axis2 inside Spring, i.e. to configure and manage the Axis2 runtime (including the deployed services) using Spring application contexts. This is a serious limitation.

Apache CXF

CXF is a merger of two prior OSS projects - Celtix ObjectWeb and XFire projects. CXF support JAX-WS, RESTful and POJO for the building Web Servicess. CXF support SOAP, JMS, CORBA and more.

CXF has better support for JAX-WS and offers seamless integration with Spring framework. CXF is slim, intuitive, performs well and is easy to use. Invoking a Web Services using CXF will boost developer productivity since all marshalling/un-marshalling and transfer of data is taken care of automatically.

CXF is designed with Spring in mind and supports the Spring 2.0 XML syntax, making it trivial to declare endpoints which are backed by Spring and inject clients into the application.

CXF is the also tool of choice if a SOAP engine has to be embedded into existing software.

GlassFish Metro

The Metro Web Services stack is a part of the GlassFish community, but it can be also used outside GlassFish. The core of Metro implements the JAX-WS API and serves as the foundation where all the higher-level features plug in.

Metro is known to have poorly documented its APIs.

Metro also only works with JAXB 2.x data binding and JAX-WS 2.x Web Services configuration, as opposed to the wider range of data bindings and alternative configuration supported by Axis2 and CXF.

Popularity Analysis

Below is a trend analysis that shows the requirement for major Web Service frame work (source: http://www.indeed.com ) over the last 5 years.

SAAS Simple Maturity Model

There are two architectural models – commonly referred as SAAS Maturity models- that describe the transition of a service to what is called Multi-tenant efficient, highly scalable application. The SAAS Maturity model described by Microsoft has four distinct stages and is illustrated below. Another similar well-known model for SaaS-maturity is known as Forrester-model but adds another stage known as "Dynamic Business Apps-as-a-service". The three key Attributes of a SAAS Architecture: Configurability: Metadata used to configure the way the application behaves for customers Multi-tenant Efficiency : Maximizing the sharing of resources across tenants Scalability: Maximizing concurrency, resource efficiency SAAS Simple Maturity Model (Microsoft, 2006) SaaS Maturity Model (Forres...

CXF Example –Web Service Using Spring and Maven

Apache CXF is an open source services framework. CXF helps you build Web Services using frontend programming APIs, like JAX-WS and JAX-RS. These services can speak a variety of protocols such as SOAP, XML/HTTP, RESTful HTTP, or CORBA and work over a variety of transports such as HTTP, JMS or JBI. Support for bottom up approach and top down approach. Support for Standards JAX-WS, JSR-181, SAAJ, JAX-RS SOAP 1.1, 1.2, WS-I BasicProfile, WS-Security, WS-Addressing, WS-RM, WS-Policy WSDL 1.1 MTOM Building Web Services – Example 1 Develop a simple Web Service using CXF framework. The example in this case is an InterestRate Service. Tools / technologies Version CXF 2.1 Maven 2.0 Tomcat apache-tomcat-6.0.24 JDK java version 1.6.0_20       The Application Scope The "Interest Rate Service" application demonstrates how easily you can develop a Web Service using CXF frame work. The WSDL service definition defines three operations. Below is the InterestRateService interface.   @WebS...

CXF – Webservice Example – Contract first

We will use the same WSDL document that we used in our earlier example. The contract is given below: Step: 1 Run the wsdl2java tool to generate the requires service class, JAXB input output message classes. wsdl2java.bat -d src -ant -impl -server rateService.wsdl This command will generate: JAXB Input and Output message classes, Service Interface, Service Implementation class, Standalone Server class and an ant build file to build the service. If you open up these files in the editor, then you see various JAXB annotations on classes and methods which are used to map a Java class to XML. It will also generate Request and Response Wrapper classes as with the JAX-WS specification. It also generate Request and Response Wrapper classes as with the JAX-WS specification ...
