JNDI look-up JBOSS 7

I used to access JNDI lookup for datasource in JBOSS AS 5 as well as JBOSS AS 6 by using this way:

Unfortunately, it seems doesn't work in AS 7, as it produces error:

javax.naming.NamingException: JBAS011843: Failed instantiate InitialContextFactory org.jboss.naming.remote.client.InitialContextFactory from classloader ModuleClassLoader for Module "deployment.omega.war:main" from Service Module Loader

Thanks to this link, the solution is quite simple, only put the INITIAL_CONTEXT_FACTORY to org.jboss.as.naming.InitialContextFactory.

One additional note, put the JNDI name with prefix java:/ or java:jboss/.

Hi , i want to lookup jdbc datasource from java standalone app

//

public static void main(String[] args) throws SQLException {
DataSource cname = null;
Context context = null;

try {
Properties properties = new Properties();
properties.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.as.naming.InitialContextFactory");
context = new InitialContext(properties);
cname = (DataSource) context.lookup("java:jboss/datasources/dream");
Connection connection = cname.getConnection();
System.out.println("connection-----masum : "+ connection.isClosed());
} catch (NamingException e) {
e.printStackTrace();
}

}

Error :
//

public static void main(String[] args) throws SQLException {
DataSource cname = null;
Context context = null;

try {
Properties properties = new Properties();
properties.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.as.naming.InitialContextFactory");
context = new InitialContext(properties);
cname = (DataSource) context.lookup("java:jboss/datasources/dream");
Connection connection = cname.getConnection();
System.out.println("connection-----masum : "+ connection.isClosed());
} catch (NamingException e) {
e.printStackTrace();
}

}
