Error when trying to use Simple-JNDI

Question

For unit testing purposes, I'm trying to set up JNDI to connect to a HSQLDB without using Tomcat. To do this I am using Simple-JNDI and following this website.

So first I created a class that will initialize the a JNDI Data Source:

import org.hsqldb.jdbc.JDBCDataSource;    
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;

public class JndiDataSource {
    public void Initialize() throws NamingException {
        // Create initial context
        System.setProperty(Context.INITIAL_CONTEXT_FACTORY, "org.osjava.sj.MemoryContextFactory");
        System.setProperty("org.osjava.sj.jndi.shared", "true");
        InitialContext ic = new InitialContext();

        ic.createSubcontext("java:/comp/env/jdbc");

        // Construct DataSource
        JDBCDataSource ds = new JDBCDataSource();
        ds.setDatabase("jdbc:hsqldb:hsql://localhost/xdb");
        ds.setUser("SA");
        ds.setPassword("");

        // Put datasource in JNDI context
        ic.bind("java:/comp/env/jdbc/myDS", ds);
    }
}

Then in a unit test I'm calling Initialize() and just attempting to lookup the Data Source.

import org.junit.jupiter.api.Test;    
import javax.naming.InitialContext;
import javax.naming.NamingException;
import javax.sql.DataSource;

public class JndiDataSourceTest {
    @Test
    public void testInitialize() throws NamingException {
        JndiDataSource jds = new JndiDataSource();
        jds.Initialize();

        InitialContext ic = new InitialContext();
        DataSource ds = (DataSource)ic.lookup("java:/comp/env/jdbc/myDS");
    }
}

Unfortunately, when I try to debug this unit test it fails on the lookup, (DataSource)ic.lookup("java:/comp/env/jdbc/myDS"); The debugger says,

javax.naming.NameNotFoundException: java:/comp/env/jdbc/myDS

So the question is, what am I doing wrong?

Answer 1

May be it's a simple typo - IMHO it should be org.osjava.sj.memory.MemoryContextFactory
