SOAP and REST - both equally important to Sun

Guest Author

"Sun moving away from SOAP to embrace REST" is the misleading title
of an article recently published in href="http://www.sdtimes.com/SUN_MOVING_AWAY_FROM_SOAP_TO_EMBRACE_REST/About_JAVA_and_REST_and_SUN/32959">SD
Times. The article provides a good introduction to JAX-RS and
Jersey. But I really wonder what motivated the author of this
article to use this title. This blog, hopefully, provides a better

Jersey is
the Reference Implementation of Java API for RESTful Web Services
and was released earlier this week. The headline indicates that Sun is
leaving SOAP and will support REST. The debate between
REST and SOAP is not new and there are religious camps on both sides
(even within Sun).
And that's completely understandable because each technology has its
own merits and demerits. But just because a new JSR aimed to make
RESTful Web services easy in
the Java platform is released, it does not mean Sun Microsystems is
leaving existing technology in trenches.

The addition of Jersey to Sun's software portfolio makes the Web
services stack from GlassFish community a more compelling and
comprehensive offering. This is in contrast  to "moving away"
from SOAP as indicated by the title. As a matter of fact, Jersey will
be included as part of Metro
the Web Services stack of GlassFish. And then you can use JAX-WS (or
Metro) if you like to use SOAP or JAX-RS (or Jersey) if you prefer
RESTful Web
services. It's all about a offering choice to the community instead of
showing a direction.

Here are some data points for JAX-WS:
  • The JAX-WS 2.0 specification was released on href="http://jcp.org/aboutJava/communityprocess/final/jsr224/index.html">May
    11, 2006. There have been couple of maintenance releases
    since then and another one brewing.
  • Parts of Metro, the implementation of JAX-WS, are currently
    baked into GlassFish, embeddable in JBoss WS Stack, and also part of
    Oracle Weblogic and IBM Websphere.
  • The implementation stack is mature and used in several key
    customer deployments. 
  • JAX-WS is already included in Java SE 6 and hence available
    to a much wider audience.
  • As opposed to "moving away", JAX-WS 2.2 (currently being
    worked upon) will be included in Java EE 6 platform, as will Jersey be.

So I believe both SOAP and REST are here to stay, at least in the near
future. And Sun Microsystems is committed to support them!

You still think Sun is moving away from SOAP ?

It seems a personal preference is interpreted as Sun's disinvestment in
SOAP. It's good to have increased readership but not at the cost
of misleading headlines :)

    "...I really wonder what motivated the author of this article to use this title."

    On most magazines and newspapers, including SDTimes, (I am a columnist for them), the author of the article does not write the headline. It's written by magazine staff.

    A small point, but a common misperception.

    Really nice summary Arun - and good to hear Jersey will make it into Metro for .NET interoperability.

    Arun ,

    Does Jax-ws 2.0 support wsdl 2.0 and soap 1.2 spec ?

  • Arun Gupta Monday, October 20, 2008


    SOAP 1.2 yes, WSDL 2.0 No. AIU no customers have been asking for WSDL 2.0 yet. Are you aware of any strong usecases ?

  • Ashok Monday, October 20, 2008

    Arun , we had use case wher our customer asked a support for wsdl 2.0 . On evaluating java frame works found the Apache Axis2 folks are supporting it.

    Just wanna know whether Jax-ws supports it or not.

    If i'm correct wsdl 2.0 supports rest style invocation too rite?

  • Arun Gupta Friday, October 24, 2008

    Ashok, JAX-WS does not support WSDL 2.0 and yes WSDL 2.0 do support REST style description as well.

    bilgilendirme için çok teşekkürler başarılar diliyorum
