this is my persistence.xml file:

this is my entity class:
@Entity
@Table(name="SESSION",
uniqueConstraints={@javax.persistence.UniqueConstraint(columnNames={"SESUID"})})
@DataCache(enabled=false)
public class UserSession {
@Id
@Column(name="ID")
private Long id;
@Column(name="CRTTIM")
@Temporal(TemporalType.TIMESTAMP)
private Date loginDate;
@Column(name="TIMOUT")
private Long timeout;
@Column(name="SESUID", unique=true)
private String sessionId;
@Column(name="LSTACCSTIM")
@Temporal(TemporalType.TIMESTAMP)
private Date lastAccessTime;
@Column(name="CLNTIP")
private String clientIP;
...
}
we have old version of this entity that located in another class and there is a
bit difference in timeout variable(data type is Integer). is this difference
lead to this issue? please consider that there isn't any any scenario in
application that calls UserSessionOld class.
@Entity
@Table(name="SESSION",
uniqueConstraints={@javax.persistence.UniqueConstraint(columnNames={"SESUID"})})
@DataCache(enabled=false)
public class UserSessionOld {
@Id
@Column(name="ID")
private Long id;
@Column(name="CRTTIM")
@Temporal(TemporalType.TIMESTAMP)
private Date loginDate;
@Column(name="TIMOUT")
private Integer timeout;
@Column(name="SESUID", unique=true)
private String sessionId;
@Column(name="LSTACCSTIM")
@Temporal(TemporalType.TIMESTAMP)
private Date lastAccessTime;
@Column(name="CLNTIP")
private String clientIP;
...
}
