Can someone tell me where to find the Section?

[olszynski]

Hello,

I made my first Bean and I got following error message during startup:

09:44:50,244 INFO [EJBDeveloper]
Bean: BankAccount
Section: 9.2.9
Warning: The primary key class must override equals().


What is Section 9.2.9? Ist that a reference to a documentation? If yes, to which documantation? URL´s are welcome!

Btw. is it possible, that this Warning is wrong, because i did overrride it.
See my BankAccountPK.java:



package BankAccount;

public class BankAccountPK implements java.io.Serializable {

public String accountNumber;

public BankAccountPK(String accNo) {
accountNumber = accNo;
}

public BankAccountPK() {
accountNumber = new String();
}

public int hashCode() {
return accountNumber.hashCode();
}

public boolean equals(Object obj) {
return accountNumber.equals(obj);
}

public String toString() {
return accountNumber;
}
}

I think that is the relevant section in the EJB specification.

No, I had a look in the ejb-2-1-spec.pdf. Section 9.2 is about Remote Clients, and there isn´t a chapter 9.2.9 at all.

It does refer to an EJB spec section, most likely to 1.1 or 2.0 version

[olszynski]

Yeah you´re right it´s in the EJB Spec 1.1. Thx a lot

But the stuff what was written in this chapter didn´t help me at all. I still get the error messages like described way uo in my first posting.
Does anybody have a clue why I get such an error message with right (in my opinion) code?

[sgturner]

My clue is this. Methods are uniquely identified by method name plus signature. You can have multiple methods with same name. So, given that, it may be expecting

public boolean equals (BankAccountPK) not

public boolean equals (Object)

[olszynski]

Thanks for your idea.
I tried it right now and I got the same errormessage....must override equals .......
So that was not the problem.

I still haven´t solved this problem. Anybody here who has got some ideas? The code is so easy and I think right.
