Transport scheme NOT recognized: [tcp]

Question

It has been years since I worked with activeMQ some. I am now implementing a new activeMQ server with client apps on the inside and outside.

I tested my outside client app locally, but when I deployed it, I started getting errors like:

2014-04-10 08:01:31,392 [signInResultListenerContainer-1] ERROR org.springframework.jms.listener.DefaultMessageListenerContainer - Could not refresh JMS Connection for destination 'queue://signInResult' - retrying in 5000 ms. Cause: Could not create Transport. Reason: java.io.IOException: Transport scheme NOT recognized: [tcp]

I checked the firewall on my server and it is wide open.

<bean id="amqConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
    <property name="brokerURL" value="tcp://xxx.30.8.163:61616"/>
</bean>

Any ideas on what is causing the error?

Answer 1

I believe you don't have the necessary resources in your classpath. Take a look at this similar issue and check the ActiveMQ jars/resources from the classpath.

The easiest way to resolve is to prefill the ConnectionFactory with connections by setting the prefill element to true in the ra config

        <connection-definitions>
            <connection-definition class-name="org.apache.activemq.ra.ActiveMQManagedConnectionFactory" jndi-name="java:/ConnectionFactory" enabled="true" pool-name="ConnectionFactory">
                <xa-pool>
                    <min-pool-size>1</min-pool-size>
                    <max-pool-size>20</max-pool-size>
                    <prefill>true</prefill>
                    <is-same-rm-override>false</is-same-rm-override>
                </xa-pool>
            </connection-definition>
        </connection-definitions>

I'm using Spring Boot, and this is what solved it for me:

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-activemq</artifactId>
    </dependency>
