[jboss-user] [JNDI/Naming/Network] - EJB3 Client with JBoss, exception: java.lang.NoSuchFieldErro

[mrducnguyen]

I'm trying to use EBJ3 to manage a table in my database, when I created a test client, I always received this: 

Exception in thread "main" java.lang.NoSuchFieldError: TRACE
  |     at org.jboss.logging.Log4jLoggerPlugin.isTraceEnabled(Log4jLoggerPlugin.java:85)
  |     at org.jboss.logging.Logger.isTraceEnabled(Logger.java:122)
  |     at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:660)
  |     at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:627)
  |     at javax.naming.InitialContext.lookup(InitialContext.java:392)
  |     at TestEJBClient.main(TestEJBClient.java:31)

Although I have created two properties files and referenced all the jar in the JBOSS_HOME/client directory... I'm stuck
Anyone  please help! I need to do this urgently.

Below is all the code:

// Table ADMIN: 
  | //    Username nvarchar(20) PK
  | //    Password nvarchar(20)
  |  
  | **** Entity bean: Admin ****
  | @Entity
  | @Table(name = "Admin", schema = "dbo", catalog = "TungaRestaurant", uniqueConstraints = {})
  | public class Admin implements java.io.Serializable {
  | 	private String username;
  | 	private String password;
  |  
  | 	public Admin(String username, String password) {
  | 		this.username = username;
  | 		this.password = password;
  | 	}
  |  
  | 	@Id
  | 	@Column(name = "Username", unique = true, nullable = false, insertable = true, updatable = true, length = 20)
  | 	public String getUsername() {
  | 		return this.username;
  | 	}
  | 	public void setUsername(String username) {
  | 		this.username = username;
  | 	}
  |  
  | 	@Column(name = "Password", unique = false, nullable = false, insertable = true, updatable = true, length = 20)
  | 	public String getPassword() {
  | 		return this.password;
  | 	}
  | 	public void setPassword(String password) {
  | 		this.password = password;
  | 	}
  | }
  |

  | 	}
  |  
  | 	public int delete(String usr) {
  | 		int retVal = 0;
  | 		Admin admin = em.find(Admin.class, usr);
  | 		try
  | 		{
  | 			em.remove(admin);
  | 		}
  | 		catch (Exception ex)
  | 		{
  | 			retVal = -1;
  | 		}		
  | 		return retVal;

  | 			else

  | 				em.flush();
