When i look at my log i see that wildfly deployed my dice datasource and bound it to [java:/jdbc/dice]. It is referenced in my persistence xml.

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1"
    xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">
    <persistence-unit name="dice">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <jta-data-source>jdbc/dice</jta-data-source>

Now i want to check some datasource settings at startup to ensure isolation level and so on:

@Singleton
@Startup
public class ConfigService {
    @Resource(name = "java:/jdbc/dice")
    private DataSource dataSource;

In the startup method i just do things like:

        Connection connection = dataSource.getConnection();
        boolean autoCommit = connection.getAutoCommit();
        int isolationLevel = connection.getTransactionIsolation();

At startup i always get:

If i change the jndi name of the Datasource injection it works (eg. dice only), but i do not understand why. What am i doing wrong?

greetings, m

Answer 1

@Resource(lookup = "java:jboss/datasources/dice")
private DataSource dataSource;

I missused the @Resource annotation and used name instead of lookup. (switched the jndi name just for testing. in case you wonder)
