Transport scheme NOT recognized: [nsp]

Question

I am trying to connect to a SoftwareAg's Universal Messaging queue in a Spring application. This is my Config class.

@Configuration
@EnableJms
public class Config {

    @Bean
    public ActiveMQConnectionFactory receiverActiveMQConnectionFactory() {
        ActiveMQConnectionFactory activeMQConnectionFactory = new ActiveMQConnectionFactory();

        var properties = new Properties();
        properties.setProperty(Context.INITIAL_CONTEXT_FACTORY, "com.pcbsys.nirvana.nSpace.NirvanaContextFactory");
        properties.setProperty(Context.PROVIDER_URL, "nsp://localhost:9200");
        activeMQConnectionFactory.buildFromProperties(properties);

        return activeMQConnectionFactory;
    }

    @Bean
    public DefaultJmsListenerContainerFactory jmsListenerContainerFactory() {
        var factory = new DefaultJmsListenerContainerFactory();
        factory.setConnectionFactory(receiverActiveMQConnectionFactory());
        factory.setConcurrency("3-10");
        return factory;
    }

} 

This is the part of my pom.xml

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-activemq</artifactId>
</dependency>
<dependency>
    <groupId>org.apache.activemq</groupId>
    <artifactId>activemq-broker</artifactId>
</dependency>
<dependency>
    <groupId>com.pcbsys.nirvana</groupId>
    <artifactId>nClient</artifactId>
    <version>1.0</version>
</dependency>
<dependency>
    <groupId>com.pcbsys.nirvana</groupId>
    <artifactId>nJMS</artifactId>
    <version>1.0</version>
</dependency>

However, I get the following exception when I try to connect to the queue:

It says here:

UM can be used with Spring. In general, the Spring XML that works for ActiveMQ should work for UM with only the connection factory class and URL changed accordingly.

What am I missing?

Edit:

var properties = new Properties();
properties.setProperty(Context.INITIAL_CONTEXT_FACTORY, "com.pcbsys.nirvana.nSpace.NirvanaContextFactory");
properties.setProperty(Context.PROVIDER_URL, "nsp://localhost:9200");

Context ctx = new InitialContext(properties);
return (ConnectionFactory) ctx.lookup("local_um"); // THIS?

I finally managed to solve it. This is what worked for me:

@Configuration
@EnableJms
public class Config {

    @Bean
    public DefaultJmsListenerContainerFactory jmsListenerContainerFactory() {
        var factory = new DefaultJmsListenerContainerFactory();
        factory.setConnectionFactory(cachingConnectionFactory());
        factory.setConcurrency("3-10");
        return factory;
    }

    @Bean
    @Primary
    public CachingConnectionFactory cachingConnectionFactory() {
        final CachingConnectionFactory cachingConnectionFactory = new CachingConnectionFactory();
        cachingConnectionFactory.setSessionCacheSize(200);
        cachingConnectionFactory.setTargetConnectionFactory((ConnectionFactory) jndiObjectFactoryBean().getObject());

        return cachingConnectionFactory;
    }

    @Bean
    public JndiTemplate jndiTemplate() {
        final Properties properties = new Properties();
        properties.setProperty(Context.INITIAL_CONTEXT_FACTORY, "com.pcbsys.nirvana.nSpace.NirvanaContextFactory");
        properties.setProperty(Context.PROVIDER_URL, "nsp://local-dev:9200");

        final JndiTemplate jndiTemplate = new JndiTemplate();
        jndiTemplate.setEnvironment(properties);

        return jndiTemplate;
    }

    @Bean
    public JndiObjectFactoryBean jndiObjectFactoryBean() {
        final JndiObjectFactoryBean jndiObjectFactoryBean = new JndiObjectFactoryBean();
        jndiObjectFactoryBean.setJndiTemplate(jndiTemplate());
        jndiObjectFactoryBean.setJndiName("jndi_key");
        return jndiObjectFactoryBean;
    }

}

I hope it helps someone. Don't forget to add nClient.jar and nJMS.jar to your classpath. You can find them in the UM install lib directory.
