Hello,
I’m new in vaadin. I use NetBeans 8.1 (with Vaadin add-on), Oracle XE 11g and Tomee (plume) 1.7.4. I have created a new vaadin web application project with some addons: lazycontainer, viritin, jpacontainer. Here’s the deps from the pom.xml:

[/size]I use only one entity In my example project. There is a MappedSuperclass for common fileds…
[...]
@MappedSuperclass
public class BaseModel implements Serializable {
@Id
@Column(name = "ID")
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "DefaultSequence")
private Long id;
@Basic(optional = false)
@NotNull
@Column(name = "CREATED")
@Temporal(TemporalType.TIMESTAMP)
private Date created;
[...]
… and here’s the entity:
[...]
@Entity
@Table(name = "CLASSTYPES")
@XmlRootElement
@NamedQueries({
@NamedQuery(name = "Classtypes.findAll", query = "SELECT c FROM Classtypes c"),
[...]
@SequenceGenerator(name="S_CLASSTYPES", sequenceName="S_CLASSTYPES", allocationSize=1)
public class Classtypes extends BaseModel implements Serializable {
private static final long serialVersionUID = 1L;
@Basic(optional = false)
@NotNull
@Size(min = 1, max = 250)
@Column(name = "NAME")
private String name;
@Lob
@Column(name = "DESCRIPTION")
private String description;
@OneToMany(mappedBy = "classtypeId")
private List<Classes> classesList;
public Classtypes() {
}
[...]
I have added a persistence.xml to the project, then I have modified by hand. Here’s the result:
<?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="SourcePU" transaction-type="RESOURCE_LOCAL">
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>

<properties>
<property name="eclipselink.jdbc.platform"
value="org.eclipse.persistence.platform.database.OraclePlatform" />
<property name="eclipselink.jdbc.driver" value="oracle.jdbc.OracleDriver" />
<property name="eclipselink.jdbc.url" value="jdbc:oracle:thin:@localhost:1521:XE" />
<property name="eclipselink.jdbc.user" value="sandbox" />
<property name="eclipselink.jdbc.password" value="sandbox" />
<property name="eclipselink.logging.level" value="FINE" />
<property name="eclipselink.ddl-generation" value="none" />
<property name="eclipselink.ddl-generation.output-mode"
value="database" />
</properties>
</persistence-unit>
</persistence>Ok. Let’s try to select:
JPAContainer<Classtypes> container = JPAContainerFactory.make(Classtypes.class, "SourcePU");It works perfectly. The result is all (three) “records”. Good.
Then let’s try to insert:
Classtypes cc = new Classtypes();
cc.setName("xxx"); //...and all mandatory fileds are filled.
container.addEntity(cc); The result is an exception:
java.lang.IllegalStateException:
Exception Description:
Cannot use an EntityTransaction while using JTA.

Ahhh…what did I miss?
Thx.
