部署在Tomcat Web服务器上的Axis2 Web服务代码中的ServiceLoader用法

Question

I have an .aar file deployed on Tomcat,Axis2 platform in Ubuntu. I'm using Oracle JDK1.7 Tomcat 7.0.35 and Axis2 1.6.2

Recently I made a refactoring to use java.util.ServiceLoader class to load implementations of some classes dynamically.

Here is my aar file structure:

META-INF folder

services.xml Contains info about the web service

services folder
    com.companyname...interfacename1 (contains implementation class name)
    com.companyname...interfacename2 (contains implementation class name)
    com.companyname...interfacename3 (contains implementation class name)

com folder
    companyname folder
        bla bla.class compiled class files here

In my Eclipse Development environment, my methods run w/o any problem but when they run in Axis2 Tomcat platform, ServiceLoader class can not load implementation classes. What can be the problem? Any help is appreciated. Thanks.

Just use one of your classes to obtain their classLoader,Then use it:

    ClassLoader classLoader = com.companyname.blabla.MyClass1.getClassLoader();

    java.util.ServiceLoader.load(blabla.class,classLoader);

It works both in Tomcat,Axis2 deployed code and in development environment unit test code!
