如何用main方式启动xwork2.0？

如何用main方式启动xwork2.0？

	public static void main(String[] args) throws Exception {
		Map paramMap = new HashMap();
		paramMap.put("id", "0123456789");

		//		 set the ActionContext parameters
		Map context = new HashMap();
		context.put(ActionContext.PARAMETERS, paramMap);
		
//		ConfigurationManager cm = new ConfigurationManager();
//
//		Configuration conf = cm.getConfiguration();
//
//		
		//		 create an action proxy with no namespace, action alias (defined in xwork.xml), and a map of the context info
		ActionProxy proxy = new DefaultActionProxyFactory().createActionProxy(
				"", "viewBook", context);

		//		 we have the action proxy instance, lets execute it and retrieve the action
		String result = proxy.execute();
		if ("success".equals(result)) {
			ViewBookAction action = (ViewBookAction) proxy.getAction();

			// return info back to caller or just print to screen for this example
			System.out.println(action.getBook().getTitle());
		} else if ("notFound".equals(result)) {
			// forward to another inventory source
		} else {
			throw new RuntimeException("Im lazy");
		}

	}

以上代码会产生问题NullPointer异常,看代码好象是Container没有注入,原来的代码是

ActionProxy proxy = ActionProxyFactory().getFactory().createActionProxy(
				"", "viewBook", context);

但是2.0根本就不能如此用.刚刚接触xwork.

改成如下方式就可以了:

package com.jamesby.xwork.helloworld;

import java.util.HashMap;
import java.util.Map;

import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionProxy;
import com.opensymphony.xwork2.DefaultActionProxyFactory;
import com.opensymphony.xwork2.config.Configuration;
import com.opensymphony.xwork2.config.ConfigurationManager;
import com.opensymphony.xwork2.inject.Container;

public class BookMain {

	public static void main(String[] args) throws Exception {
		Map paramMap = new HashMap();
		paramMap.put("id", "0123456789");
		Map context = new HashMap();
		context.put(ActionContext.PARAMETERS, paramMap);
		ConfigurationManager cm = new ConfigurationManager();
		Configuration conf = cm.getConfiguration();
		Container containter = conf.getContainer();
		DefaultActionProxyFactory actionProxyFactory = new DefaultActionProxyFactory();
		actionProxyFactory.setContainer(containter);
		ActionProxy proxy = actionProxyFactory.createActionProxy(
				"", "viewBook", context);
		String result = proxy.execute();
		if ("success".equals(result)) {
			ViewBookAction action = (ViewBookAction) proxy.getAction();
			System.out.println(action.getBook().getTitle());
			System.out.println("Success.................");
		} else if ("notFound".equals(result)) {
		} else {
			throw new RuntimeException("Im lazy");
		}

	}

}

		System.out.println("my result is invoked..............");
	}

}

大哥你的程序  能跑对吗？

具体说一下你的 配置文件怎么放，都在什么位置， ！！
