hi, Iam having the same problem again and again. I really dont know how I can get rid of this problem when I use JNDI template. Iam using camel basic example.
JMS SU xbean.xml <beans xmlns:jms="http://servicemix.apache.org/jms/1.0"; xmlns:tut="http://intra.agfanet"; xmlns:tutorial="urn:org:apache:servicemix:tutorial:camel" xmlns:amq="http://activemq.org/config/1.0"; xmlns="http://www.springframework.org/schema/beans"; xmlns:xsi="http://http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://servicemix.apache.org/jms/1.0 http://servicemix.apache.org/schema/servicemix-jms-3.2.2.xsd http://activemq.org/config/1.0 http://activemq.apache.org/schema/core/activemq-core-4.1.1.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd";> <!-- START SNIPPET: provider --> <jms:endpoint service="tut:jms" endpoint="myProvider1" role="provider" destinationStyle="queue" jmsProviderDestinationName="queue/testQueue" connectionFactory="#connectionFactory" defaultMep="http://www.w3.org/2004/08/wsdl/in-only"; /> <bean id="jbossJndiTemplate" class="org.springframework.jndi.JndiTemplate"> <property name="environment"> <props> <prop key="java.naming.factory.initial"> org.jnp.interfaces.NamingContextFactory </prop> <prop key="java.naming.provider.url"> jnp://localhost:1099 </prop> <prop key="java.naming.factory.url.pkgs"> org.jboss.naming:org.jnp.interfaces </prop> </props> </property> </bean> <bean id="connectionFactory" class="org.springframework.jndi.JndiObjectFactoryBean"> <property name="jndiTemplate"> <ref bean="jbossJndiTemplate" /> </property> <property name="jndiName"> <value>java:QueueConnectionFactory</value> </property> <property name="resourceRef" value="true"/> </bean> </beans> Camel MyRouteBuilder.java public class MyRouteBuilder extends RouteBuilder { public void configure() { //send a message to a JBI endpoint... from("timer://tutorial?fixedRate=true&delay=3000&period=30000") // 1 .setBody(constant("<message>Hello world</message>")) // 2 .to("jbi:endpoint:http://intra.agfanet/jms/myProvider1";); } } My intension is to write on a queue name queue/testQueue. So that the messageDrivenBean deployed on Jboss gets this message. But, Iam having the following errors and exceptions.
