Try the following descriptor for your Person entity bean in ejb-jar.xml. I
think that should work.
<entity>
<ejb-name>person.Person</ejb-name>
<home>person.PersonHome</home>
<remote>person.Person</remote>
<ejb-class>person.PersonBean</ejb-class>
<persistence-type>Container</persistence-type>
<prim-key-class>person.PersonPK</prim-key-class>
<reentrant>False</reentrant>
<cmp-field>
<field-name>personid_</field-name>
</cmp-field>
<cmp-field>
<field-name>name_</field-name>
</cmp-field>
<cmp-field>
<field-name>address_</field-name>
</cmp-field>
<cmp-field>
<field-name>phone_</field-name>
</cmp-field>
</entity>

Subject: Re: Primary key class in container managed entity bean, int type
My problem is that the code that produces the error is generated by ejbc. I
can't make that change. Rather, I have to somehow change how I define the
primary key class, the home interface, or the deployment descriptor to make
the generator understand that the primary key class cannot be directly
compared to a native type, but should call the equals method of the primary
key class that I have defined.
Does that make more sense?

use
pk.personid_ = bean.personid_;
instead... if that's not what you are asking, elaborate a little further

Subject: Primary key class in container managed entity bean, int type
I cannot seem to make this work no matter what I do. I want to create a
primary key class that contains an integer as the primary key, and the table
I am trying to access a table called person, which I've created just to see
if I can get this to work.
I've included all of the source below, exluding the deployment descriptors,
but I definitely name the person.PersonPK as the primary key class. The
problem is that the code for the bean implementation is attempting to set an
instance of my primary key class to the value of my bean's instance of
personid_:
person.PersonPK pk = null;
try {
bean.ejbCreate( arg0, arg1, arg2, arg3);
pk = bean.personid_;
....
You see that pk is of type person.PersonPK, and bean.personid_ is an int.
Of course this is a compiler error. Can anyone tell me what I am doing
wrong?
