Use AXIS2 transport attachment (AXIS2 MTOM)

1. Working environment

Ide:eclipse 3.1.2

Jdk:jdk1.5.0_04

tomcat:apache-tomcat-5.0.28

axis2:1.0 (War version and bin version)

2. Realize

To create a new Dynamic Web project in Eclipse, add the jar packages required for Axis2 under Web-inf\lib.

This example is a system of users upload download picture format File example, every time on the outgoing carry attachments, but also include file name, file type. The 2 features implemented by this webservice are upload, download.

AXIS2 's WebService was released as a Xxx.aar release, Xxx.aar the expanded directory structure

--

--meta-inf

Services.xml

--Contains the server-side implementation Class (Directory is the same structure as package)

3. Server-Side Filetransferserver.java
