在eclips里项目的属性-》Java Builder Path-》Libraries中，将axis的servlet-api.jar加入，然后在类代码中添加：

import javax.servlet.http.HttpServletRequest;

import org.apache.axis.MessageContext;
import org.apache.axis.transport.http.HTTPConstants;

MessageContext mc = MessageContext.getCurrentContext();  
  HttpServletRequest  request  =  (HttpServletRequest)  mc.getProperty(HTTPConstants.MC_HTTP_SERVLETREQUEST);
 String ipAddr = request.getRemoteAddr();

即可
