Hello friends
I am working a project .my objective is to call stored procedure in the ejb session bean class.but each time i am getting same following problem
Project :

I am doing following step :
Step 1:
i have created a stored procedure in the oracle 11 g data base
create or replace
PROCEDURE EXAMPLE
( j_job_id IN varchar2
,j_job_title IN varchar2
,j_job_min_salary IN number
,j_job_max_salary IN number
,j_job_id_out OUT varchar2
AS
BEGIN
INSERT INTO jobs (job_id,job_title,min_salary,max_salary)
VALUES (j_job_id,j_job_title,j_job_min_salary,j_job_max_salary);
END EXAMPLE;
Step 2:
then i have created a simple jobs entity class.
@Entity
@NamedQueries({
@NamedQuery(name = "Jobs.findAll", query = "select o from Jobs o")
@NamedStoredProcedureQuery(
name="EXAMPLE", procedureName="EXAMPLE",
parameters = {
@StoredProcedureParameter(queryParameter = "job_id",name = "job_id",direction=Direction.IN),
@StoredProcedureParameter(queryParameter= "job_title",name="job_title",direction=Direction.IN),
@StoredProcedureParameter(queryParameter= "min_salary",name="min_salary",direction=Direction.IN),
@StoredProcedureParameter(queryParameter= "max_salary",name="max_salary",direction=Direction.IN)
public class Jobs implements Serializable {}
Step3:
then i have created a session bean class and also created a method which called the stored procedure
public void callStoredProcedure(){
Query query=em.createNamedQuery("EXAMPLE");
query.setParameter("job_id", "ADD123");
query.setParameter("job_title", "ADD_1234");
query.setParameter("min_salary", 1234);
query.setParameter("max_salary", 3456);
query.getResultList();
Step4:
i have created a client to access this session bean method
public static void main(String [] args) {
try {
final Context context = getInitialContext();
SessionEJB sessionEJB = (SessionEJB)context.lookup("StoredProcedure-Model-SessionEJB#service.SessionEJB");
sessionEJB.callStoredProcedure();
} catch (Exception ex) {
ex.printStackTrace();
please help me out from where i am missing some thing . i try every thinks but i do not solve this problem .thanks i advance

thanks for reply .
i have removed the out parameter and my stored procedure look like following statement :
create or replace
PROCEDURE EXAMPLE
( j_job_id IN varchar2
,j_job_title IN varchar2
,j_job_min_salary IN number
,j_job_max_salary IN number
AS
BEGIN
INSERT INTO jobs (job_id,job_title,min_salary,max_salary)
VALUES (j_job_id,j_job_title,j_job_min_salary,j_job_max_salary);
END EXAMPLE;
