One more minor point, you might have noticed that since the location Id in the HR
schema was a 4 digit number, I had to change the
service and the client code to insert a long.

Hence in HrmService.java the createDept method looks as follows:

public Department createDept(Long deptno, String dname,
Long loc) {
final Department dept = new Department();
dept.setDeptno(deptno);
dept.setDname(dname);
dept.setLocation(loc);
getEntityManager().persist(dept);
return dept;
}

and in HrmClient.java, the create line looks as follows:

hrmService.createDept(new Long(280),”New Dept”, new Long(1800));

Lucas,
Thanks a lot for your excellent example. Just got your example working in JDev
with the Epress database using the sample HR schema.
Needed a few minor changes to make it happen. Here they are:

1. In the persistence.xml file the value to the connection string:

2. The JDBC user and password (of course)

2. The persistence mapping entries for the persistent objects:

In Department.java

@Table(name=”DEPARTMENTS”)
public class Department implements Serializable {

@Id
@Column(name=”DEPARTMENT_ID”)
public Long getDeptno() {

@Column(name=”DEPARTMENT_NAME”)
public String getDname() {

@Column(name=”LOCATION_ID”)
public Long getLocation() {

In Employee.java

@Table(name=”EMPLOYEES”)
public class Employee implements Serializable {

@Column(name=”COMMISSION_PCT”)
public Double getComm() {

@Column(name=”DEPARTMENT_ID”)
public Long getDeptno() {

@Id
@Column(name=”EMPLOYEE_ID”, nullable=false)
public Long getEmpno() {

@Column(name=”LAST_NAME”)
public String getEname() {

@Column(name=”HIRE_DATE”)
public Timestamp getHiredate() {

@Column(name=”JOB_ID”)
public String getJob() {

@Column(name=”MANAGER_ID”)
public Long getMgr() {

@Column(name=”SALARY”)
public Double getSal() {

I’ll now start playing around with the mappings. Thanks again!

sincerely,
k7
