Error while lookup through client,unable to access the EntityBean

Version 1

    I am trying to create a Entity bean to connect with a MySql databse using remote client but its giving error,using Jboss eap 7.1,Eclipse Juno to connect with Mysql databse 5.6,below are the source codes:

     

    Entity Class:

    package com.ibytecode.entities;

     

    import java.io.Serializable;

    import javax.persistence.Entity;

    import javax.persistence.Id;

    import javax.persistence.Column;

     

    @Entity(name = "project")

    public class Project implements Serializable {

        private static final long serialVersionUID = 1L;

     

        public Project() {

            super();

        }

     

        @Id

        private int id;

        private String name;

        private String post;

     

        @Column(name = "dept_no")

        private int deptNo;

     

        public int getid() {

            return id;

        }

        public void setid(int id) {

            this.id = id;

        }

        public String getname() {

            return name;

        }

        public void setname(String name) {

            this.name = name;

        }

        public String getpost() {

            return post;

        }

        public void setpost(String post) {

            this.post = post;

        }

      

      

        @Override

        public String toString() {

            return "Project [id=" + id + ", name="

                    + name + ", post="

                    + post + "]";

        }

    }

     

    Remote Interface:

     

    package com.ibytecode.business;

    @Stateless

    public class ProjectBean implements IProject {

     

        @PersistenceContext(unitName = "JPADB")

        private EntityManager entityManager;

     

        public ProjectBean() {   }

     

        @Override

        public void saveProject(Project project) {

            entityManager.persist(project);

        }

     

        @Override

        public Project findProject(Project project) {

            Project p = entityManager.find(Project.class,

                        project.getid());

            return p;

        }

     

        @Override

            String q = "SELECT id from " + Project.class.getName() + " entity";

            Query query = entityManager.createQuery(q);
