Problem lors de depoiement d'une application JEE

est-ce qu'il est possible de voir ta class
com.model.User et ton fichier de conf applicationContext.xml?

ou sinon, il semble que tu veuilles caster un tableau []
en arraylist ce qui n'est pas permis.

bien sur ,
voici ma classe user:
package com.model;

// default package
// Generated 12 mai 2014 13:38:22 by Hibernate Tools 3.4.0.CR1

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import static javax.persistence.GenerationType.IDENTITY;
import javax.persistence.Id;
import javax.persistence.Table;

/**
* User generated by hbm2java
*/
@Entity
@Table(name = "user", catalog = "fac_medecine")
public class User implements java.io.Serializable {

private Integer id;
private String login;
private String password;

public User() {
}

public User(String login, String password) {
this.login = login;
this.password = password;
}

@Id
@GeneratedValue(strategy = IDENTITY)
@Column(name = "Id", unique = true, nullable = false)
public Integer getId() {
return this.id;
}

public void setId(Integer id) {
this.id = id;
}

@Column(name = "login", nullable = false, length = 50)
public String getLogin() {
return this.login;
}

public void setLogin(String login) {
this.login = login;
}

@Column(name = "password", nullable = false, length = 50)
public String getPassword() {
return this.password;
}

public void setPassword(String password) {
this.password = password;
}

}

et voici fichier de config applicationContext.xml

désolé, mais je ne vois pas où est le problème,

mais il y ce cas-ci est très similaire au tien:
