Resource injection with Embedded EJB3 Container
I am trying to unit test a SSB using the embedded container.
The problem I have is that I need a DataSource injected in the session bean:
@Resource(mappedName = "java:/GP3DS") public DataSource dataSource;
When I perform the unit test (from an Ant script), the dataSource variable is null (and as soon as accessed of course throwing a NullPointerException).
However when I look it up the "traditional" way, using InitialContext.lookup(), it works just fin.
Also, in a regular JBoss AS (I'm using 4.0.5 GA) the injection using the annotation works perfectly well.
This is the code & configuration:
the session bean
@Stateless
public class CrossRatesBean implements gp3.xrate.CrossRatesLocal {
@Resource(mappedName = "java:/GP3DS")
private DataSource dataSource;
// do some SQL stuff
}
I configured the datasource like this in
embedded-jboss-beans.xml:
<bean name="DefaultDSBootstrap" class="org.jboss.resource.adapter.jdbc.local.LocalTxDataSource"> <property name="driverClass">oracle.jdbc.OracleDriver</property> <property name="connectionURL">jdbc:oracle:thin:@gp3testserver:1521:gp3</property> <property name="userName">foo</property> <property name="password">bar</property> <property name="jndiName">java:/GP3DS</property> <property name="minSize">0</property> <property name="maxSize">10</property> <property name="blockingTimeout">1000</property> <property name="idleTimeout">100000</property> <property name="transactionManager"><inject bean="TransactionManager"/></property> <property name="cachedConnectionManager"><inject bean="CachedConnectionManager"/></property> <property name="initialContextProperties"><inject bean="InitialContextProperties"/></property> </bean> <bean name="GP3DS" class="java.lang.Object"> <constructor factoryMethod="getDatasource"> <factory bean="DefaultDSBootstrap"/> </constructor> </bean>
This code is working in the unit test:
DataSource ds = (DataSource) ctx.lookup("java:/GP3DS");
if (ds == null) {
fail("Datasource java:/GP3DS not found!");
} else {
Connection con = ds.getConnection();
Statement stmt = con.createStatement();
ResultSet rs = stmt.executeQuery("SELECT TO_CHAR(SYSDATE, 'MM-DD-YYYY HH24:MI:SS') FROM DUAL");
rs.next();
System.out.println("SYSDATE on GP3Test: " + rs.getString(1));
stmt.close();
con.close();
}
I don't understand why it should not work in the embedded container, but I cannot find what I am missing.
I'd greatly appreciate if someone could tell me what I'm doing wrong.
