使用的主要工具有： liferay-tomcat- 3.1.0 a xis-1.1 。
下载得到这两个工具的 zip 文件夹，分别解压到两个目录里，
在环境变量里把 TOMCAT_HOME, AXIS_HOME 分别指向这两个文件夹根目录。
具体配置方法分别参考
Liferay
Axis
实现功能：在 portlet 里用 SOAP 访问 Web Service ，把得到的结果显示在 Portal 界面
** 一、 ** ** 配置 Axis Server ** ** 端 **
1． 简单的服务程序，类似 hello world ，如下
package com.kevinGQ.service
HelloService.java
public class HelloService
{
public String sayHello(String name)
{
System.out.println("HelloService");
return "Axis say hello to "+name;
}
};
先把 %AXIS_HOME%/webapps/axis 文件夹放到 %TOMCAT_HOME%/webapps/ 下，把编译好的 HelloService.class 放到 axis/WEB-INF/classes 里。
在 server-config.wsdd 里添加如下 XML 片断
1<service name="HelloService" provider="java:RPC">
2<parameter name="allowedMethods" value="sayHello"></parameter>
3<parameter name="className" value="com.kevinGQ.service.HelloService"></parameter>
4</service>
** 二、 ** ** 写 portlet ** ** 的三个 JSP ** ** 文件（参照 liferay ** ** 里的 weather portlet ** ** ） **
** 1. ** ** init.jsp **
1@ include file="/html/common/init.jsp"
1<portlet:defineobjects></portlet:defineobjects>
1
2
3PortletPreferences prefs = renderRequest.getPreferences();
4
5String[] names = prefs.getValues("names", new String[0]);
** 2. ** ** view.jsp **
1@ include file="/html/portlet/hello/init.jsp"
1@ page import="com.kevinGQ.portlet.hello.util.*"
1@ page import="com.kevinGQ.portlet.hello.model.Hello"

** 三、 ** ** 相关的 java ** ** 文件 **
** 1． ** ** HelloUtil.java **
package com.kevinGQ.portlet.hello.util;
import com.kevinGQ.portlet.hello.model.Hello;

Cache cache = WebCachePool.get(
HelloUtil.class.getName() + name, wc);
return (Hello)cache.getObject();
}
}
** 2. HelloConverter.java ** ** 实现 SOAP ** ** 调用的主要类，加粗的代码尤为重要，不写的话 Axis Server ** ** 端将会抛出错误。 **

}
return hello;
}
public long getRefreshTime(){
return _refreshTime;
}
private long _refreshTime = Time.DAY;
private String _name;
}
** 3. ** ** Hello.java **
package com.kevinGQ.portlet.hello.model;

}
