I have an example project. It contains the source, dataset, and exploded EAR. It is a
self-contained, zipped Eclipse project. How can I send it to you?
Question: When I look at the getIdList() method of the RelationSet class in package
org.jboss.ejb.plugins.cmp.jdbc.bridge, I see the exception is thrown when setHandle[0]
is null. IF this is a list of my D entites, then is the exception thrown because I
have no D entities (In my example, I remove the D entities before the parant C
entity)? If so, how can I remove a C entity?
As requested here is the sample dataset using Hypersonic SQL:
| create table TABLE_A
| (
| TABLE_A_ID VARCHAR(2) not null,
| VALUE_A1 VARCHAR(16),
| primary key (TABLE_A_ID)
| );
| create table TABLE_B
| (
| TABLE_B_ID VARCHAR(2) not null,
| TABLE_A_ID VARCHAR(2),
| VALUE_B1 VARCHAR(8),
| primary key (TABLE_B_ID)
| );
| create table TABLE_C
| (
| TABLE_C_ID VARCHAR(2) not null,
| TABLE_A_ID VARCHAR(2),
| VALUE_C1 VARCHAR(8),
| primary key (TABLE_C_ID)
| );
| create table TABLE_D
| (
| TABLE_D_ID VARCHAR(2) not null,
| TABLE_C_ID VARCHAR(2),
| VALUE_D1 VARCHAR(8),
| primary key (TABLE_D_ID)
| );
|
| alter table TABLE_B add constraint TABLE_B_FK1 foreign key (TABLE_A_ID) references
TABLE_A;
| alter table TABLE_C add constraint TABLE_C_FK1 foreign key (TABLE_A_ID) references
TABLE_A;
| alter table TABLE_D add constraint TABLE_D_FK1 foreign key (TABLE_C_ID) references
TABLE_C;
|
| insert into TABLE_A values ('a1', 'value_a1');
| insert into TABLE_B values ('b1', 'a1', 'value_b1');
| insert into TABLE_B values ('b2', 'a1', 'value_b2');
| insert into TABLE_C values ('c1', 'a1', 'value_c1');
| insert into TABLE_C values ('c2', 'a1', 'value_c2');
| insert into TABLE_D values ('d1', 'c1', 'value_d1');
| insert into TABLE_D values ('d2', 'c2', 'value_d2');
| insert into TABLE_D values ('d3', 'c2', 'value_d3');
