Hello, I'm working with CMP ejbs and I have trouble with mappings. When my java attribute and table column have the same name, all is allright. But when the names are differents, an alter table is done to add a new column with the java attribute name. (and, of course, I can't change database model neither java attributes names) (migrating our EJB applications from weblogic 8.1 to Tomee 1.7.2) example: java attribute: annualSalary <=> table column: annual_salary
Here my openejb-jar.xml, for information: <?xml version="1.0" encoding="UTF-8"?> <openejb-jar xmlns="http://www.openejb.org/xml/ns/openejb-jar-2.1"; xmlns:nam="http://geronimo.apache.org/xml/ns/naming-1.1"; xmlns:pkgen="http//www.openejb.org/xml/ns/pkgen-2.0" xmlns:sec="http://geronimo.apache.org/xml/ns/security-1.1"; xmlns:sys="http://geronimo.apache.org/xml/ns/deployment-1.1";> <cmp-connection-factory> <resource-link>ejbPool_esd</resource-link> </cmp-connection-factory> <enterprise-beans> <entity> <ejb-name>CustomerEJB</ejb-name> <table-name>CUSTOMER</table-name> <cmp-field-mapping> <cmp-field-name>annualSalary</cmp-field-name> <table-column>annual_salary</table-column> </cmp-field-mapping> <query> <query-method> <method-name>findAll</method-name> <method-params /> </query-method> <ejb-ql>SELECT OBJECT(c) FROM CUSTOMER as c</ejb-ql> </query> </entity> </enterprise-beans> </openejb-jar> So, I'm trying to add annotations on java attributes: @Entity @Table(name="CUSTOMER") public class Customer implements ... .... @Column(name="annual_salary") public Double annualSalary; But, nothing changes. So, I'm trying to add an orm.xml file like this: <entity-mappings version="1.0" xmlns="http://java.sun.com/xml/ns/persistence/orm"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://java.sun.com/xml/ns/persistence/orm http://java.sun.com/xml/ns/persistence/orm_1_0.xsd";> <entity class="........CustomerBean" name="CustomerEJB" access="PROPERTY"> <attributes> <basic name="annualSalary"> <column name="annual_salary" /> </basic> </attributes> </entity> </entity-mappings> , but I get an exception: org.apache.openejb.OpenEJBException: Creating application failed: K:\apache-tomee-plus-1.7.2\apps\ejb.esd1.0.3: Error building bean 'Customer1EJB'.
