PostgreSQL key generation
Hello all
I use JbOss 4.0.2 & PostgreSQL 8
I have create simple entity bean and I want use key generator (simple autoincrement)
this is ejb-jar.xml
<ejb-name>PersonEJB</ejb-name>
amc.ejb.cmp.PersonHome
amc.ejb.cmp.Person
<local-home>amc.ejb.cmp.LocalPersonHome</local-home>
amc.ejb.cmp.LocalPerson
<ejb-class>amc.ejb.cmp.PersonBean</ejb-class>
<persistence-type>Container</persistence-type>
<prim-key-class>java.lang.Long</prim-key-class>
False
<cmp-version>2.x</cmp-version>
<abstract-schema-name>PersonEJB</abstract-schema-name>
<cmp-field>
<field-name>personid</field-name>
</cmp-field> - KEY FIELD
<cmp-field>
<field-name>status</field-name>
</cmp-field>
<cmp-field>
<field-name>docid</field-name>
</cmp-field>
<primkey-field>personid</primkey-field>
I have tried different ways for fix this problem in jboss-jdbc.xml
first try
<ejb-name>PersonEJB</ejb-name>
<table-name>tbl_persons</table-name>
<cmp-field>
<field-name>docid</field-name>
<column-name>DOCID</column-name>
</cmp-field>
<cmp-field>
<field-name>status</field-name>
<column-name>STATUS</column-name>
</cmp-field>
<cmp-field>
<field-name>personid</field-name>
<column-name>PERSON_ID</column-name>
<auto-increment/>
</cmp-field>
<entity-command name="postgresql-fetch-seq"/>
second
<ejb-name>PersonEJB</ejb-name>
<table-name>tbl_persons</table-name>
<cmp-field>
<field-name>docid</field-name>
<column-name>DOCID</column-name>
</cmp-field>
<cmp-field>
<field-name>status</field-name>
<column-name>STATUS</column-name>
</cmp-field>
<unknown-pk>
<unknown-pk-class>java.lang.Long</unknown-pk-class>
<field-name>personid</field-name>
<column-name>PERSON_ID</column-name>
<jdbc-type>LONG</jdbc-type>
<sql-type>BIGSERIAL</sql-type>
<auto-increment/>
</unknown-pk>
<entity-command name="postgresql-fetch-seq"/>
public abstract class PersonBean implements EntityBean {
public Long ejbCreate() throws javax.ejb.CreateException{
return null;
}
But that I get, when call create() method
Could not create entity:java.sql.SQLException: ERROR: null value in column "person_id" violates not-null constraint
What I do wrong?
