I've got a Map containing MyObject instances. The MyObject class uses JPA to persist its fields: @OneToMany(cascade = CascadeType.ALL) @LazyCollection(LazyCollectionOption.FALSE) private Map<String, MyObject> results = new HashMap<String, MyObject>(); We changed the value stored by the Map to a List : private Map<String, List<MyObject>> results = new HashMap<String, List<MyObject>>(); But upon launching we receive a stack trace: Caused by: org.hibernate.AnnotationException: Use of @OneToMany or @ManyToMany targeting an unmapped class: com.me.myapp.MyObject.results[java.util.List] at org

I have the following test.. @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations = {"/schedule-agents-config-context.xml"}) @TransactionConfiguration(transactionManager = "transactionManager", defaultRollback = true) @Transactional public class H2TransactionNotWorkingTest extends SubmitAgentIntegratedTestBase { private static final int FIVE_SUBMISSIONS = 5; @Autowired private ApplicationSubmissionInfoDao submissionDao; private FakeApplicationSubmissionInfoRepository fakeRepo; @Before public void setUp() { fakeRepo = fakeRepoThatNeverFails(submissionDao, null);

I'm working on play 2.0.1 application deployed on openshift DIY-application. I'm having troble with the database because play keeps trying to evolve the wrong database. I have a mysql database and play creates an H2 database evolution script. Here are the scripts. What he is trying to create create table gif ( id bigint not null, title varchar(255), add_date timestamp, gif_url varchar(255), img_source varchar(5000), web_id varchar(255), found_on varchar(255), thumbnail varchar(255), version integer not null, constraint pk_gif primary key (id)) ; create table task ( id bigint not null, action

I have a SAMPLE_TABLE with a column BIZ_ID which should be unique when the column active is not equal to 0. On an oracle database the index looks like this: CREATE UNIQUE INDEX ACTIVE_ONLY_IDX ON SAMPLE_TABLE (CASE "ACTIVE" WHEN 0 THEN NULL ELSE "BIZ_ID" END ); How would this unique index look like on a h2 database? In H2, you could use a computed column that has a unique index: create table test( biz_id int, active int, biz_id_active int as (case active when 0 then null else biz_id end) unique ); --works insert into test(biz_id, active) values(1, 0); insert into test(biz_id, active) values(1,

I am using H2 database for integration test. The code is quiet old and is using JDBC queries instead. While running tests i am getting the error below org.h2.jdbc.JdbcSQLException: Function "TO_CHAR" not found; SQL statement: I can see that H2 does not implecitely supports TO_CHAR function. Is there any way to add a custom methor or should i think about moving to HSQL DB or any other database for testing purpose. Use the newer version 1.3.175. Since 2014-01-18 available with a TO_CHAR function. You could try HSQLDB of course. I think it does support TO_CHAR. Or you could write a user defined
