axis使用和配置1.docx

1、axis使用和配置1在某些场景中AXIS提供很强大的功能，包括添加消息头，提供NTLM等多种认证方式，进行ACK发送的功能，具体参考SAP 的AXIS FQA。本文档主要讲述PI的AXIS部署以及自定handler，涉及2个handler,一个用于外围系统异步发送系统的时候发生ACK给外围系统，另一个是PI采用Handler实现NTLM V2安全认证。 SP15 , SP10之后SAP推出了针对Apache HTTP Client library的补丁，参考note 2062567 - Integration of Apache HttpClient library in the PI Axi

2、s adapter可以实现NTLM V2。而对于这2个补丁之前的版本SAP不支持 NTLM V2协议。本例的方法是根据SAP的SP包中的相关类进行反编译后的源代码封装成自己的handler类。首先PI要支持AXIS，则需要部署部署情况可以通过网址 jar（开始使用版本，发现有bug: ） (NTLM V2 用到此包，下面的2个包也一样) 用工具sdaMakerTool进行压缩。如果是自己开发的handler类没有用到其他PI标准类的话也可以独立部署到这个包中，如果用到了其他类，其他的jar类也一并压缩到这个包中，并要进行加载，另外一种方式是把自定的handler类在SAP 的axis samp

3、le adapter中实现，参考AXIS的FQA.本文档中的两个类都是独立的类，用到的SAP标准的jar文件也压缩到其中。ACK handler类实现，网上有这个blog，照着blog实现。代码如下。package class ZResponseHandler extends BasicHandler protected static Log log = public void invoke(MessageContext msgContext) throws AxisFault /* Response handler to write custom Ariba response */ try
