在EJB中运行客户端代码时出错

Question

在EJB中运行客户端代码时出错：

线程“Main thread”java中出现异常。lang.NoClassDefFoundError:weblogic上的weblogic/kernel/KernelStatus。jndi。环境（Environment.java:78）在weblogic。jndi。WLInitialContextFactory。javax上的getInitialContext（WLInitialContextFactory.java:117）。命名。spi。NamingManager。javax上的getInitialContext（NamingManager.java:667）。命名。InitialContext。javax上的getDefaultInitCtx（InitialContext.java:288）。命名。InitialContext。javax上的init（InitialContext.java:223）。命名。InitialContext。（InitialContext.java:197）at User。main（User.java:21）

我添加了wlfullclient.jar，服务器的远程接口jar，我还看到了一篇文章，其中我看到添加wlclient.jar和weblogic.jar，但后来也出现了同样的错误。

客户端代码：

import com.amdocs.Stateful.*;
import java.util.Hashtable;
import javax.naming.InitialContext;
import javax.naming.NamingException;

public class User 
{
public static void main(String args[]){
Hashtable<String,String> ht = new Hashtable<String,String>();

ht.put(InitialContext.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory");// you have to start from root location to search for JNDI tree
//JNDI registry tree is normally maintained as Binary tree, JNDi is normally binary tree which have root node at top

ht.put(InitialContext.PROVIDER_URL,"t3://localhost:7001"); // address of registry
try{
    System.out.println("Hello");
    InitialContext ic = new InitialContext(ht); // start searching wrt what we set in ht , it's constructor takes HashTable only

    System.out.println("Hello2");
    MyCartRemote ref=(MyCartRemote)ic.lookup("MyCartBeanJNDI#com.amdocs.Stateful.MyCartRemote");
    ref.add("Hi");
    ref.add("Jeetendra");

    MyCartRemote ref1=(MyCartRemote)ic.lookup("MyCartBeanJNDI#com.amdocs.Stateful.MyCartRemote");
    ref1.add("Hi");
    ref1.add("Subhash");
    ref1.add("Ghai");

    System.out.println("Object 1 data: "+ref.show());
    System.out.println("Object 2 data: "+ref1.show());
}
catch (NamingException e){      e.printStackTrace();    }
}
}

尝试从引导条目部分删除WebLogic系统库。当我遇到同样的错误时，它对我起了作用。
