Implementation of WebService transfer file (AXIS2 MTOM)

Working Environment : Ide: eclipse 3.1.2                      jdk:jdk1.5.0_06                      tomcat:apache-tomcat-5.5.15                      axis2:1.0 ( War version and bin version)   Environment preparation: http://ws.apache.org/axis2/download/1_0/download.cgi to download AXIS2 Binary distribution Url:http ://apache.justdn.org/ws/axis2/1_0/axis2-std-1.0-bin.zip and War distribution URL:HTTP://APACHE.JUSTDN.ORG/WS/AXIS2/1 _0/axis2-1.0-docs.zip. Unzip the two files, such as C:/axis2-std-1.0-bin and C:/axis2.war, after extracting the extracted directory. Under Eclipse, create a new User library via the menu Window-preferences...--java-build Path-user libraries, such as the name Axis2 C:/axis2-std-1.0-bin All jar files under/lib are included in. Copy the Axis2.war to the%tomcat-home%/webapps below.              &NBsp;       Implement: Create a new project in Eclipse, install Eclipse Tomcat plugin A new Tomcat project well, build path contains the user Library:axis2 created above. My example scenario is a voicemail system for users to upload download greeting language pieces (greeting), each voicemail system user has a unique mailbox number, greeting has different types, such as busy time greeting, travel time greeting, different periods of greeting,   The greeting file supports types that are Wav,mp3 and so on.   So my webservice to achieve 2 functions is upload, download. AXIS2 's WebService was released as a Xxx.aar release, Xxx.aar the expanded directory structure to----Meta-inf services.xml--Contains the server-side implementation of C Lass (Directory with package is the same structure) new 2 classes: Filetransferclient.java, Interopservice.java.
