Summary: CMR and ejbCreate
Initial Comment:
Hi,
I have a problem regarding CMR. As for example, I have
two tables “Test” and “TestParams”. The tables
definitions are as follows:
Test
test_id varchar(20) not null– primary key
test_name varchar(20) not null
TestParams
test_id varchar(20) not null – primary key (references to
testID in Test)
examiner varchar(20) not null – primary key
length int not null
I am trying to establish a 1:N relationship between
them. I have the relevant getters and setters in the
two entity beans.
Getters/Setters in Test:
public abstract Collection getTestParamLists();
public abstract void setTestParamLists(Collection
testParamLists);
Getters/Setters in TestParams:
public abstract TestLocal getTest();
public abstract void setTest(TestLocal test);
Below are the extracts from the ejb-jar and jbosscmp-
jdbc:
Ejb-jar:
<relationships>
<ejb-relation>
<ejb-relation-name>Test-TestParams</ejb-relation-
name>

</ejb-relationship-role>
<ejb-relationship-role>
<ejb-relationship-role-name>Params-belong-
to-Test</ejb-relationship-role-name>
</ejb-relationship-role>
</ejb-relation>
</relationships>
I tried to create a Test bean and a TestParams bean by
issuing the following codes:
TestLocal newTest=testLocalHome.create(testobject);
testParamsLocalHome.create(paramObject, newTest);
The Test bean is successfully created, but not the
TestParams bean.
I got the following error:
javax.ejb.CreateException: javax.ejb.CreateException:
Could not create entity:java.sql.SQLException: Unknown
column 'test' in 'field list'
I looked at the log file and it has the following info:
Executing SQL: INSERT INTO TEST_PARAMS (test_ID,
examiner, length, test) VALUES (?, ?, ?, ?)
It seems like Jboss thinks that my cmr field is a cmp
field? What do I need to change?
Any help is appreciate.
