I've a doubt with EJB Lite 3.1 embeddable:
I'm using EJB Lite for a app JSE; the call of EJB components are OK! The
problem only appear when I try
do a connection using JTA for the database.
See:
<code>
@Stateless
@DataSourceDefinition(name="java:app/jdbc/estudo",
databaseName="estudo",
password="123456",
user="postgres",
className="org.postgresql.Driver",
portNumber=5432,
serverName="localhost")
public class DataSourceCustomBean {
@PersistenceContext(unitName="ExemploEJbPU")
private EntityManager em;
</code>
This datasource is who provides the data-source-name for references in the
persistence.xml. See the persistence.xml:
<code>
<?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="ExemploEJbPU" transaction-type="JTA">
<jta-data-source>java:app/jdbc/estudo</jta-data-source>
<properties>
<property name="eclipselink.ddl-generation" value="update"/>
</properties>
</persistence-unit>
</persistence>
</code>
The call this component is definied below:
<code>
EJBContainer container = EJBContainer.createEJBContainer();
InitialContext context = (InitialContext) container.getContext();
DataSourceCustom dataSource = (DataSourceCustom)
context.lookup("java:global/classes/DataSourceCustomBean");
</code>
In the moment I try run the application, appear the following stack,
<code>

Waiting for suggestions. Tks
