I'm working on a JavaEE application with EJB.
I have an Entity called Medico which code is:
@Entity public class Medico implements Serializable{ /** * */ private static final long serialVersionUID = 1L; /** * */ public Medico(String nome_medico, String morada_medico, String esp, GregorianCalendar dnasc_medico, int tel_medico) { //construtor parametrico super(); this.nome_medico = nome_medico; this.morada_medico = morada_medico; this.esp = esp; this.dnasc_medico = dnasc_medico; this.tel_medico = tel_medico; } @Id @GeneratedValue private int cod_medico; //bi private String nome_medico; private String morada_medico; private String esp; @Temporal(TemporalType.DATE) private GregorianCalendar dnasc_medico; private int tel_medico; private ArrayList<GregorianCalendar> agenda_consultas; private ArrayList<GregorianCalendar> agenda_atos; private int total_atos; private int total_presc; public int getTotal_presc() { return total_presc; } public void setTotal_presc(int total_presc) { this.total_presc = total_presc; } public Medico(){ //construtor vazio super(); } public int getTotal_atos() { return total_atos; } public void setTotal_atos(int total_atos) { this.total_atos = total_atos; } public ArrayList<GregorianCalendar> getAgenda_consultas() { return agenda_consultas; } public void setAgenda_consultas(ArrayList<GregorianCalendar> agenda_consultas) { this.agenda_consultas = agenda_consultas; } public ArrayList<GregorianCalendar> getAgenda_atos() { return agenda_atos; } public void setAgenda_atos(ArrayList<GregorianCalendar> agenda_atos) { this.agenda_atos = agenda_atos; } public int getCod_medico() { return cod_medico; } public void setCod_medico(int cod_medico) { this.cod_medico = cod_medico; } public String getNome_medico() { return nome_medico; } public void setNome_medico(String nome_medico) { this.nome_medico = nome_medico; } public String getMorada_medico() { return morada_medico; } public void setMorada_medico(String morada_medico) { this.morada_medico = morada_medico; } public String getEsp() { return esp; } public void setEsp(String esp) { this.esp = esp; } public GregorianCalendar getDnasc_medico() { return dnasc_medico; } public void setDnasc_medico(GregorianCalendar dnasc_medico) { this.dnasc_medico = dnasc_medico; } public int getTel_medico() { return tel_medico; } public void setTel_medico(int tel_medico) { this.tel_medico = tel_medico; } @Override public String toString() { return "Medico [cod_medico=" + cod_medico + ", nome_medico=" + nome_medico + ", morada_medico=" + morada_medico + ", esp=" + esp + ", dnasc_medico=" + dnasc_medico + ", tel_medico=" + tel_medico + "]"; } } Then I created a session bean implementation class:
@Stateless public class HospitalManagement implements AdministradorSessionRemote,GestorSessionRemote { /** * Default constructor. */ @PersistenceContext(unitName="Hospital") private EntityManager em; public HospitalManagement() { // TODO Auto-generated constructor stub } @Override public String cria_medico(String nome_medico, String morada_medico, String esp, GregorianCalendar dnasc_medico, int tel_medico) { Medico md = new Medico (nome_medico, morada_medico, esp, dnasc_medico,tel_medico); em.persist(md); return "Medico "+Integer.toString(md.getCod_medico())+" criado!"; } This class implements two interfaces, but the method above is only used in the following one:
@Remote public interface GestorSessionRemote { public String cria_medico(String nome_medico,String morada_medico,String esp,GregorianCalendar dnasc_medico, int tel_medico); public String procura_nome_medico(String nome); public String procura_cod_medico(int cod); public String altera_morada_med(int cod, String morada); public String altera_telemovel_med(int cod, int tel); Then I created a client:
public class GestorClient { public static void main(String[] args){ InitialContext ctx =new InitialContext(); GestorSessionRemote g=(GestorSessionRemote)ctx.lookup("java:global/HospitalEAR/Hospital/HospitalManagement!Sessions.GestorSessionRemote"); System.out.println(g.cria_medico(nomem, moradam, esp,cal,telm)); where the parameters of the method are obtained by scannig from the keyboard.
I've also created the following persistence.xml file:
<?xml version="1.0" encoding="UTF-8"?> <persistence version="2.1" xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd"> <persistence-unit name="Hospital"> <properties> <property name="javax.persistence.schema-generation.database.action" value="drop-and-create"/> </properties> </persistence-unit> </persistence> When I try to deploy the application, an error occurs. Here is the complete stacktrace:
