CMP Deployment Error

[jacques_buitendag]

Hi All,

I am getting the following error when I try and deploy my CMP entity bean

Warning: The type of the primkey-field must match the primary key class.

I am using java.lang.Long as primary Key and JBoss is creating the primary key colum as BIGINT

Here is an part of my ejb-jar.xml file

<persistence-type>Container</persistence-type>
<prim-key-class>java.lang.Long</prim-key-class>
False
<cmp-version>2.x</cmp-version>
<abstract-schema-name>RegisteredClass</abstract-schema-name>
<cmp-field>
<field-name>SerialVerUID</field-name>
</cmp-field>
<cmp-field>
<field-name>RegisteredClassName</field-name>
</cmp-field>
<primkey-field>SerialVerUID</primkey-field>

Could anyone help me

Kind Regards
Jacques Buitendag

remove <prim-key-class> declaration from your ejb-jar.xml

Hi Juha

I tried that method but then the problem was that the generated SQL gave errors.

But on the other side I found the problem.

my primary key getters and setters where still of type long and not of type java.lang.Long.

My question now is: how can you use primitive types as primary keys in CMP?

Kind Regards

just declare the field as 'long' in your CMP implementation and mark it as your primary key field in ejb-jar.xml. Do not use primkey-class at all, it is only necessary for composite primary keys
