JBOSS下开发部署EJB问题！！！

gavinchang

大家好，我按照网上和书上的一些例子，编写了一个STATELESS SESSION EJB，想把它部署到jboss上，
我用的是JDK1.5 JBOSS4.0.2 RHAS4.0
我把程序编写好，编译，打包成Helloworld.jar并部署到$JBOSS_HOME$/server/default/deploy下,该EJB能被自动部署执行,但是我的测试程序却不能运行,请大家帮忙看一下程序和错误,还有,如果我把JDK换成1.4版本的,该EJB在JBOSS下就不能被部署,但是我把<精通JBOSS>中的一个例子拿来部署到jdk1.4版本下运行的JBOSS中,却能被部署,请问这是为什么啊?
还有一个问题,在WINDOWS下,打开JBOSS的WEB-CONSOLE,能看到左边的APPLET,但是在LINUX下却看不到,而且WEB-CONSOLE左侧显示的JVM ENVIRONMENT中的MEMORY,在WINDOWS中的也比LINUX的大

ejb-remote:

public interface Hello extends javax.ejb.EJBObject{
public String hello() throws java.rmi.RemoteException;
}

ejb-home:

public interface HelloHome extends javax.ejb.EJBHome{
Hello create() throws java.rmi.RemoteException,javax.ejb.CreateException;
}


ejb-localremote:

public interface HelloLocal extends javax.ejb.EJBLocalObject{
public String hello();
}

ejb-localhome:

public interface HelloLocalHome extends javax.ejb.EJBLocalHome{
HelloLocal create() throws javax.ejb.CreateException;
}

ejb-bean:

import javax.ejb.*;
public class HelloBean implements javax.ejb.SessionBean{
private javax.ejb.SessionContext ctx;
public void ejbCreate(){
System.out.println("ejbCreate");
}
public void ejbRemove(){
System.out.println("ejbRemove");
}
public void ejbActivate(){
System.out.println("ejbActivate");
}
public void ejbPassivate(){
System.out.println("ejbPassivate");
}
public void setSessionContext(javax.ejb.SessionContext ctx){
this.ctx=ctx;
}
public String hello(){
System.out.println("hello()");
return "hello.world!";
}
}


客户端测试程序:

import javax.naming.Context;
import javax.naming.InitialContext;
import java.util.Properties;
import java.rmi.RemoteException;
import java.util.Hashtable;
import javax.ejb.CreateException;
import javax.ejb.FinderException;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import javax.rmi.PortableRemoteObject;
public class HelloClient{
public static void main(String args[])throws Exception{
Properties props=new Properties();
props.put(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");
props.put(Context.PROVIDER_URL,"localhost");
Context ctx=new InitialContext(props);
Object obj=ctx.lookup("HelloBeanHomeRemote");
HelloHome Home=(HelloHome)javax.rmi.PortableRemoteObject.narrow(obj,HelloHome.class);
Hello hello=Home.create();
System.out.println(hello.hello());
hello.remove();
}
}

你的类库路径问题系统找不到所需要的类,编译出错Root exception is java.lang.ClassNotFoundException:
