[jira] [Created] (OPENJPA-2615) EJB CMP: field mapping ejb
attribute with different table column name
DORE created OPENJPA-2615:
-----------------------------
Summary: EJB CMP: field mapping ejb attribute with different table column name
Key: OPENJPA-2615
URL: https://issues.apache.org/jira/browse/OPENJPA-2615
Project: OpenJPA
Issue Type: Bug
Components: Enhance, jpa, kernel
Affects Versions: 2.4.0
Environment: tomee
Reporter: DORE
Hello OpenJPA community,
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)
example:
java attribute: annualSalary <=> table column: annual_salary
Here my openejb-jar.xml, for information:
{code}
<?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>
{code}
So, I'm trying to add annotations on java attributes:
{code}
@Entity
@Table(name="CUSTOMER")
public class Customer implements ...
....
@Column(name="annual_salary")
public Double annualSalary;
{code}
But, nothing changes.
So, I'm trying to add an orm.xml file like this:
{code}
<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">
<table name="CUSTOMER" />
<attributes>
<basic name="annualSalary">
<column name="annual_salary" />
</basic>
</attributes>
</entity>
</entity-mappings>
{code}
, but I get an exception:
{code}

I don't understand why, and nothing in exception points the defect.
