I understand the problem now. The custom classes that I put in the shared repository of tomcat reference the classes in the alfresco.war. While a child class loader can delegate his parent class loader to load class, a parent class loader cannot delegate class loading to his child class loader. That is to say, when tomcat shared loader is loading my custom classes, it cannot get the alfresco classes referenced by my custom classes loaded. So the tomcat shared loader cannot load my custom classes at all. That is the explanation.

A workaround is to produce a amp file which contains the customized classes. Then integrated the alfresco.war + amp file by using an alfresco tool to produce a new alfresco.war who contains the customization.

This post has helped me to find the explanation:
