====================================================
 
 
个人认为webservices的发展,已渐渐地从观念证明
走向实用. 而软件大厂们(Microsoft, IBM, Sun,
Oracle, BEA, ....)发展webservices目的当然也
不只是为了证明利用SOAP/WSDL可以interop.
相信都是认定了Business Process,Grid Computing
这方向的价值. 但这些技术,当然都是建立在
interoperable的SOAP/WSDL之上.

应此个人认为, 必须要有一个符合 WSI-BasicProfile
以及JAX-RPC, JSR-109(J2EE WebService)的SOAP/WSDL
基础.

再在此基础之上建立 WebServices Security,
OASIS(Sun, Oracle, Fujitsu)的WebServices Reliability
或Microsoft, IBM, BEA 的Web Services Reliable Messaging
以及企业应用必要的WebServices Transaction.

关于最基础的SOAP/WSDL实现, 个人的建议是:

-如果完全自己实现:
    1. 首先必须要有JAXB以及SAAJ的实现
    2. 如果选择自己实现JAXB及SAAJ, 建议可以考虑使用
        streaming pull parser (JSR-173, StAX)
    3. 使用 JAXB来实现 Schem2Java Java2Schema Binding
    4. 实现 WSDL2Java, Java2WSDL Binding.
    5. 符合 WSI-BasicProfile 以及 JAX-RPC 的要求
    6. 考虑是否支持WSI-BasicProfile范围以外的功能,
        如SOAP-Encoded(SOAPEncodingStyle).
如此,就有一个与Axis相当的SOAP/JAX-RPC实现 ...

-如果直接使用Axis:
    1. 整合 Axis (Axis有EJB provider)与 JFox的EJB,
        以及 Tomcat(还是这已有Servlet实现?)来完成实现
        JSR-109 J2EE Web Services的要求
    2. 在此基础之上建立 WS Security
        (any Security efforts in huihoo.org?)
    3. 整合JfoxMQ(JM)来实现WS Reliability.

当然, 这只是很粗略了大纲, 希望大家可以继续讨论
