deployment error ,jpa(wl10.3.3)

[mach zro]

I tried to write a simple appn using jpa

   
BookBank.java
package entity.library;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Table;
import java.util.Collection;
import javax.persistence.*;
import java.io.Serializable;

@Entity
@Table(name="bookbank")
public class BookBank implements Serializable {

long id;
String title;
String author;
double price;

//protected Collection <LineItems> lineitems;

public BookBank() {
super();
}

public BookBank(String title, String author, double price) {
super();
this.title = title;
this.author = author;
this.price = price;
}

@Id
@GeneratedValue(strategy=GenerationType.AUTO)

// Getter and setter methods for the defined properties..

public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}

public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}

public String getAuthor() {
return author;
}

public void setAuthor(String author) {
this.author = author;
}

public double getPrice() {
return price;
}
public void setPrice(double price) {
this.price = price;
}

}
 

Business Interface:BookCatalogInterface.java

   
package entity.library;

import javax.ejb.Remote;
import java.util.Collection;
@Remote
public interface BookCatalogInterface {
public void addBook(String title, String author, double price);
public Collection <BookBank> getAllBooks();
}
 

SessionBean : BookCatalogBean.java

    
package entity.library;

import java.util.Iterator;
import java.util.Collection;
import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import java.io.Serializable;
import javax.ejb.Remote;
@Remote(BookCatalogInterface.class)
@Stateless
public class BookCatalogBean implements Serializable, BookCatalogInterface {
@PersistenceContext(unitName="EntityBean")
EntityManager em;
protected BookBank book;
protected Collection <BookBank> bookList;

public void addBook(String title, String author, double price) {
// Initialize the form
if (book == null)
book = new BookBank(title, author, price);
em.persist(book);
}

public Collection <BookBank>getAllBooks() {
bookList=em.createQuery("from BookBank b").getResultList();
return bookList;
}
}

persitent.xml

   
<persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">

</properties>
</persistence-unit>
</persistence>
 

But getting error at the time of deployment on weblogic 10.3.3 server:

try to be more clear, i'm in lack of ideas in this problem, even it sounds like a classic :I have spend hours trying to play around with this but have got nowhere.
please suggest solution

BookCatalogBean.java specify @Stateless(mappedName="entity/library/BookCatalogInterface")
and WebClient.jsp with bci = (BookCatalogInterface) ic.lookup("entity/library/BookCatalogInterface");
But getting error
Error:Unable to resolve 'entity.library.BookCatalogInterface'. Resolved 'entity.library'
I check jndi tree on console which specify Binding Name:
entity.library.BookCatalogInterface#entity.library.BookCatalogInterface
