在EJB中运行客户端代码时出错 [英] Error while running client code in EJB

问题描述

线程主线程中的异常java.lang.NoClassDefFoundError：
weblogic / kernel / KernelStatus在
weblogic.jndi.Environment。（Environment.java:78）at
weblogic.jndi.WLInitialContextFactory.getInitialContext（WLInitialContextFactory.java:117）
at
javax.naming.spi.NamingManager.getInitialContext（NamingManager.java:667）
在
javax.naming.InitialContext.getDefaultInitCtx（InitialContext.java:288）
在javax.naming。在
下的InitialContext.init（InitialContext.java:223）
javax.naming.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，我也看到了我看到添加的文章 wlclient.jar 和 weblogic.jar ，但也有相同的错误。

帮助高度赞赏。

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）; //你必须从根位置开始搜索JNDI树
 // JNDI注册表树是正常的维护为二进制树，JNDi通常是二叉树，顶端有根节点
 
 ht.put（InitialContext.PROVIDER_URL，t3：// localhost：7001）; //注册地址
 try {
 System.out.println（Hello）; 
 InitialContext ic = new InitialContext（ht）; //开始搜索wrt我们在ht中设置什么，它的构造函数只使用HashTable 
 
 System.out.println（Hello2）; 
 MyCartRemote ref =（MyCartRemote）ic.lookup（MyCartBeanJNDI＃com.amdocs.Stateful.MyCartRemote）; 
 ref.add（嗨）; 
 ref.add（Jeetendra）; 
 
 MyCartRemote ref1 =（MyCartRemote）ic.lookup（MyCartBeanJNDI＃com.amdocs.Stateful.MyCartRemote）; 
 ref1.add（嗨）; 
 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（）; 
} 
} 
  

解决方案

尝试从引导条目部分中删除WebLogic系统库。当我遇到相同的错误时，它对我有用。

Getting error while running client code in EJB:

Exception in thread "Main Thread" java.lang.NoClassDefFoundError: weblogic/kernel/KernelStatus at weblogic.jndi.Environment.(Environment.java:78) at weblogic.jndi.WLInitialContextFactory.getInitialContext(WLInitialContextFactory.java:117) at javax.naming.spi.NamingManager.getInitialContext(NamingManager.java:667) at javax.naming.InitialContext.getDefaultInitCtx(InitialContext.java:288) at javax.naming.InitialContext.init(InitialContext.java:223) at javax.naming.InitialContext.(InitialContext.java:197) at User.main(User.java:21)

I added wlfullclient.jar, server's Remote interface jar, also I saw article in which I saw to add wlclient.jar and weblogic.jar but then also got same error.

Help highly appreciated.

Client code:

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();    }
}
}

解决方案

Try removing WebLogic System Libraries from the Bootstrap Entries section. It worked for me when i got the same error.
