Key: CAMEL-1636
URL: https://issues.apache.org/activemq/browse/CAMEL-1636
Project: Apache Camel
Issue Type: Improvement
Components: bean-integration
Affects Versions: 2.0-M1
Environment: geronimo-jetty6-javaee5-2.1.4, java 6
Reporter: alexander j. perez tchernov
I think that we need an tutorial / example how to use camel with JMS queue
created in geronimo-jetty-2.1.4 . I have got NPE when try to use camel
producer in simple servlet
I have created
--------- Simple Producer ---
public class SimpleProducer {
@EndpointInject(uri="activemq:queue:SendReceiveQueue")
ProducerTemplate producer;
public void produceMessage() {
producer.sendBody("<message>test</message>"); }
}
--------- WEB-INF/applicationContext.xml---
<context:component-scan base-package="org.camel.test.conf"/>
<context:annotation-config />
<bean id="producer" class="org.camel.test.conf.SimpleProducer"/>
<bean id="activemq" class="org.apache.camel.component.jms.JmsComponent">
<property name="connectionFactory">
<bean class="org.apache.activemq.ActiveMQConnectionFactory">
<property name="brokerURL"
value="tcp://localhost:61616"/>
</bean>
</property>
</bean>
-------- UserServlet -------------
public class UserServlet extends javax.servlet.http.HttpServlet implements
javax.servlet.Servlet{
@Resource(name="jms/TestConnectionFactory")
private ConnectionFactory connectionFactory;
@Resource(name="jms/TestQueue")
private Queue queue;
protected void doGet (...) {
//use EJB 3.0 injected resources - works fine
producer.send(session.createMessage());
// NPE
new SimpleProducer().produceMessage();
}
}
-------- NPE -------------
Geronimo Application Server started
INFO RMI TCP Connection(7)-169.254.167.193

Classpath processing mode is in effect.
This option can be altered by specifying

Specify ="true" for more lenient processing such as ignoring missing jars and
references that are not spec compliant.
