测试EJB实体bean出错!

异常信息：

类层次结构：

Test.java:

package com.entity;
import javax.naming.*;  
import java.util.Properties;  
import java.util.List; 
import java.util.Iterator; 
public class Test {
	public static void main(String args[]){
		Properties props = new Properties(); 
	    props.setProperty("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory"); 
	    props.setProperty("java.naming.provider.url", "localhost:1099"); 
	    props.setProperty("java.naming.factory.url.pkgs", "org.jboss.naming");  
	    try {          
	    	InitialContext ctx = new InitialContext(props); 
	      PersonFacadeRemote persondao = (PersonFacadeRemote) ctx.lookup("java:PersonFacade/remote"); 
	      List<Person> list=persondao.findAll();
	      Iterator<Person> it = list.iterator();
	      while(it.hasNext()){
	        Person p = (Person)it.next(); 
	          System.out.println("人员编号:"+ p.getPersonid() + "\t姓名："+ p.getPersonName() + "<Br>"); 
	        } 
	    } catch (Exception e) { 
	      System.out.println(e.getMessage()); 
	    } 
	}
}

我用单独的web测试都可行，为何在包里用含main的简单java类就不能测试通过呢？？？？？？

如果我去掉下面语句：

Properties props = new Properties(); 
props.setProperty("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory"); props.setProperty("java.naming.provider.url", "localhost:1099"); 
props.setProperty("java.naming.factory.url.pkgs", "org.jboss.naming");

又出错： javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial at javax.naming.spi.NamingManager.getInitialContext(NamingManager.java:645) at javax.naming.InitialContext.getDefaultInitCtx(InitialContext.java:288) at javax.naming.InitialContext.getURLOrDefaultInitCtx(InitialContext.java:325) at javax.naming.InitialContext.lookup(InitialContext.java:392) at com.entity.Test.main(Test.java:11)

我就是想知道，如何用一个简单的java含main程序测试entity bean，最好给出代码！

确保导入ejb所需要的jar包

[itzyjr]

我导入包后，再运行"run as java application",出错： javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial at javax.naming.spi.NamingManager.getInitialContext(NamingManager.java:645) at javax.naming.InitialContext.getDefaultInitCtx(InitialContext.java:288) at javax.naming.InitialContext.getURLOrDefaultInitCtx(InitialContext.java:325) at javax.naming.InitialContext.lookup(InitialContext.java:392) at examples.AccountClient.main(AccountClient.java:22)

具体怎么导入？导入哪些文件有要求吗？导入后就可直接
