Configuring a JTA datasource for JBoss 8 (WildFly)


So, I read several times that if you use a Java EE container, you do not need to add environment params to an InitialContext in order to be able to use JNDI.

So I tried this:

@Bean public DataSource dataSource() { JndiDataSourceLookup jndiDataSourceLookup = new JndiDataSourceLookup(); return jndiDataSourceLookup.getDataSource("java:global/ExpensesDataSource"); }

However, retrieving a datasource using JNDI like this gives me a NoInitialContextException, telling me to specify the environment params.

Now, okay, so seems I was wrong to think it would work so flawlessly, so I tried retrieving the datasource like this:

@Bean public DataSource dataSource() { Properties jndiProperties = new Properties(); jndiProperties.setProperty(Context.PROVIDER_URL, "jnp://localhost:1099"); jndiProperties.put("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory"); jndiProperties.put("java.naming.factory.url.pkgs", "org.jboss.naming.org.jnp.interfaces"); JndiDataSourceLookup jndiDataSourceLookup = new JndiDataSourceLookup(); jndiDataSourceLookup.setJndiEnvironment(jndiProperties); return jndiDataSourceLookup.getDataSource("java:global/ExpensesDataSource"); }

However this gives me a javax.naming.CommunicationException: Failed to connect to server localhost:1099

I've also tried just using localhost:1099 or localhost, none of them worked.

So my question is: do I even need to specify these properties, since JBoss 8 is a Java EE container to my knowledge. And if so, what provider url do I need to specify here?


If you use javax.naming.InitialContext, you don't need to specify environment params, just like you said. For example:

InitialContext ctx = new InitialContext(); DataSource ds = (DataSource)ctx.lookup("java:jboss/datasources/ExampleDS");

Not sure how JndiDataSourceLookup works..

For looking up a datasource, you can inject it using @Resource (inside an ejb context)

@Resource(name= "java:jboss/datasources/ExampleDS") private Datasource ds;

Hope it helps!
