Difference between Apache CXF and Axis

Question

What are the advantages of using Apache CXF over Apache Axis and vice versa?

Answer 1

The advantages of CXF:

1. CXF supports for WS-Addressing, WS-Policy, WS-RM, WS-Security and WS-I BasicProfile.
2. CXF implements JAX-WS API (according by JAX-WS 2.0 TCK).
3. CXF has better integration with Spring and other frameworks.
4. CXF has high extensibility in terms of their interceptor strategy.
5. CXF has more configurable feature via the API instead of cumbersome XML files.
6. CXF has Bindings：SOAP,REST/HTTP, and its Data Bindings support JAXB 2.0,Aegis, by default it use JAXB 2.0 and more close Java standard specification.
7. CXF has abundant toolkits, e.g. Java to WSDL, WSDL to Java, XSD to WSDL, WSDL to XML, WSDL to SOAP, WSDL to Service.

The advantages of Axis2:

1. Axis2 also supports WS-RM, WS-Security, and WS-I BasicProfile except for WS-Policy, I expect it will be supported in an upcoming version.
2. Axis has more options for data bindings for your choose
3. Axis2 supports multiple languages—including C/C++ version and Java version.
4. Axis2 supports a wider range of data bindings, including XMLBeans, JiBX, JaxMe and JaxBRI as well as its own native data binding, ADB. longer history than CXF.

In Summary: From above advantage items, it brings us to a good thoughts to compare Axis2 and CXF on their own merits. they all have different well-developed areas in a certain field, CXF is very configurable, integratable and has rich tool kits supported and close to Java community, Axis2 has taken an approach that makes it in many ways resemble an application server in miniature. it is across multiple programming languages. because its Independence, Axis2 lends itself towards web services that stand alone, independent of other applications, and offers a wide variety of functionality.

As a developer, we need to accord our perspective to choose the right one, whichever framework you choose, you’ll have the benefit of an active and stable open source community. In terms of performance, I did a test based the same functionality and configed in the same web container, the result shows that CXF performed little bit better than Axis2, the single case may not exactly reflect their capabilities and performance.

In some research articles, it reveals that Axis2′s proprietary ADB databinding is a bit faster than CXF since it don’t have additional feature(WS-Security). Apache AXIS2 is relatively most used framework but Apache CXF scores over other Web Services Framework comparatively considering ease of development, current industry trend, performance, overall scorecard and other features (unless there is Web Services Orchestration support is explicitly needed, which is not required here)
