Hi,
I managed to crete my image field in MS SQL to get file larger than 8Ko
I create a Blob in my entity
| package com.edieyes.oma.entities;
|
| import java.io.InputStream;
| import java.sql.Blob;
| import java.sql.Date;
|
| import javax.persistence.Basic;
| import javax.persistence.Entity;
| import javax.persistence.FetchType;
| import javax.persistence.GeneratedValue;
| import javax.persistence.Id;
| import javax.persistence.Lob;
| import javax.persistence.Table;
|
| import org.hibernate.annotations.Type;
|
| @Entity
| @Table(name="FichierOma")
| public class FichierOma {
|
| Integer id;
| String numCommande;
| String numJob;
| String idClient;
| Date insertDate;
| Blob fichierOma;
| /**
| * @return Returns the fichierOma.
| */
| @Lob @Basic(fetch = FetchType.EAGER)
| public Blob getFichierOma() {
| return fichierOma;
| }
| /**
| * @param fichierOma The fichierOma to set.
| */
| public void setFichierOma(Blob fichierOma) {
| this.fichierOma = fichierOma;
| }
|
| /**
| * @return Returns the id.
| */
| @Id
| @GeneratedValue
| public Integer getId() {
| return id;
| }
| /**
| * @param id The id to set.
| */
| public void setId(Integer id) {
| this.id = id;
| }
| /**
| * @return Returns the idClient.
| */
| public String getIdClient() {
| return idClient;
| }
| /**
| * @param idClient The idClient to set.
| */
| public void setIdClient(String idClient) {
| this.idClient = idClient;
| }
| /**
| * @return Returns the insertDate.
| */
| public Date getInsertDate() {
| return insertDate;
| }
| /**
| * @param insertDate The insertDate to set.
| */
| public void setInsertDate(Date insertDate) {
| this.insertDate = insertDate;
| }
| /**
| * @return Returns the numCommande.
| */
| public String getNumCommande() {
| return numCommande;
| }
| /**
| * @param numCommande The numCommande to set.
| */
| public void setNumCommande(String numCommande) {
| this.numCommande = numCommande;
| }
| /**
| * @return Returns the numJob.
| */
| public String getNumJob() {
| return numJob;
| }
| /**
| * @param numJob The numJob to set.
| */
| public void setNumJob(String numJob) {
| this.numJob = numJob;
| }
|
| }
|
and I get in my SQL SERVER
id : int
idClient : varchar(255)
fichierOma : image
insertDate : datetime
numCommande : varchar(255)
numJob : varchar(255)
but now I ve got another problem
when I want to insert an entity I get this error message
