JDev EJB Tutorial problem

Question

JDev v.9.0.3.2(build 1145)
Using the built-in help facility instructions on the EJB Tutorial, I am stuck on Part 5; Step 1.
(Copied directly from tutorial)
*****begin tutorial instructions*******
Step 1: Adding a Create Method to the Entity Bean
The first step is to add a new create() method on the Dept entity bean.
To add a new create() method: In the Navigator, double-click Dept to open the EJB Module Editor.
Expand the node for Dept and click the Methods node.
In the Method Category list, choose Create methods.
Click Add.
In the Method Details dialog box, in the Parameters field, type the following:Long deptno, String dname, Long manager, Long location Click OK to close the dialog.
Your new create() method appears in the list of methods. Click OK to close the EJB Module Editor.
To add code to the Dept entity bean: In the Navigator, expand the node for the Dept bean and double-click DeptBean.java.
In the Structure pane, double-click ejbCreate(long, String, long, long) to jump to that method in the code.
Replace the stub method with the following code:
public DeptPK ejbCreate(Long deptno, String dname, Long manager, Long location)
this.setDepartment_id(deptno);
this.setDepartment_name(dname);
this.setManager_id(manager);
this.setLocation_id(location);
return new DeptPK(deptno);
In the Navigator, right click DeptBean.java and choose Make DeptBean.java to make sure it compiles without errors.

I cannot get the 'hrApp' EJB to compile.
The compiler complaint:
Error(18,10): class DeptPK not found in class hr.impl.DeptBean
Error(24,16): class DeptPK not found in class hr.impl.DeptBean
Any recommendations are appreciated.
Thanks,

Answer 1

Mistake: misnamed the bean in problem statement.
I meant to say the 'DeptBean' (not hrApp EJB) did not compile, using sample code from instructions.
Surely someone can help.
