Hi guys,
I'm tryin to get started with REST and JPA using TomEE Plus v1.5.1 and
Derby.
The REST part of it is all right, it's the JPA part that's drivin me nuts.
*Here are the Datasources defined in tomee.xml:*
<tomee>
...
<Resource id="test_ds" type="DataSource">
JdbcDriver org.apache.derby.jdbc.EmbeddedDriver
JdbcUrl jdbc:derby://localhost:1527/test_db;create=true
JtaManaged true
</Resource>
<Resource id="test_ds_unmanaged" type="DataSource">
JdbcDriver org.apache.derby.jdbc.EmbeddedDriver
JdbcUrl jdbc:derby://localhost:1527/test_db;create=true
JtaManaged false
</Resource>
...
</tomee>
*The persistence.xml:*
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0"
xmlns="http://java.sun.com/xml/ns/persistence";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd";>
<persistence-unit name="test_pu" transaction-type="JTA">
<provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider>
<jta-data-source>test_ds</jta-data-source>
<non-jta-data-source>test_ds_unmanaged</non-jta-data-source>
<class>de.mdesign.hellorest.entity.HelloEntity</class>
<properties>
<property name="openjpa.jdbc.SynchronizeMappings"
value="buildSchema(ForeignKeys=true)" />
</properties>
</persistence-unit>
</persistence>
For the sake of completeness, here is the whole rest of the test webapp ...
*The entity class:*
@Entity
@Table(name = "HELLO_ENTITY")
@TableGenerator(name = "HelloEntityId", table = "ID_POOL", pkColumnName =
"GEN_KEY", valueColumnName = "GEN_VALUE", pkColumnValue = "HELLO_ENTITY_ID")
@NamedQueries({ @NamedQuery(name = "HelloEntity.findAll", query = "SELECT h
FROM HelloEntity h") })
public class HelloEntity implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.TABLE, generator =
"HelloEntityId")
private Long id;
@Column
private String name;
...
}
*And finally the REST-Service:*
@Path("/rest")
@Produces({MediaType.TEXT_PLAIN})
public class HelloRest {
@PersistenceContext(unitName = "test_pu")
private EntityManager em;
@PUT
@Path("/create")
public String createEntry(@QueryParam("name") String name) {
HelloEntity hello = new HelloEntity();
hello.setName(name);
hello = em.merge(hello);
return ("Hello "+hello.getName()+" (id="+hello.getId()+")");
}
...
}
I get no errors or warnings or whatever on TomEE startup and webapp
deployment.
All datasources defined get created.
All entities are found.
What am I doin wrong ?
