On 3 virtual machines running Zookeeper + ActiveMQ.
ActiveMQ Version 5.15.9 with Camel Version 2.19.5
Now, I'm using the embedded Camel EIP Framework in ActiveMQ.
I want to get a specific node from Zookeeper based on an event.

I create a route on apache servicemix and put it in deploy. When the server started and I check the bundle:list it says that my route is in Grace Period and it's not working.
Currently I'm routing ftp to file server and do this format.
<camelContext xmlns="http://camel.apache.org/schema/blueprint">
<route>
<from uri="FTP:username#//hostname /DB?password=password"/>
<to uri="file:\\storage\folder\anotherFolder\anotherFolder\anotherFolder\"/>
</route>
</camelContext>
I did not input the exact credentials I use but that is the format that I used.
Is there any problem with my code or it's on my apache service mix? Please help I doing this for a week.
P.S. It works when its file to file server
You can install ftp using feature:install camel-ftp .

I use servicemix. I'm trying to send messages from jetty to the queue, but I get the following error:
enter image description here
my blueprint:
<camelContext xmlns="http://camel.apache.org/schema/blueprint">
<route>
<from uri="jetty:http://localhost:8180/test"/>
<to uri="activemq://events_test" />
</route>
</camelContext>
if i use route from jetty to file - everything works as it should
Exchange pattern of your route is InOut, so your jetty consumer waiting response from activemq producer. Response will appear if you have activemq consumer that will process your jetty request. If activemq producer shouldn't make response and you need just save request in queue use "inOnly" instead if "to", like this:
<inOnly uri="activemq://events_test" />
My bundle installed into karaf container 4.0.7, that use camel-quartz22.17.3
In camelContext I have many routes such as "myRoute", it call a job quatrz (using camel-quartz2) configured in postgresql database:
<camelContext id="myCamelContext" xmlns="http://camel.apache.org/schema/blueprint">
<route id="myRoute">
<from
uri="quartz2://statGroup/startupTimer?trigger.repeatInterval=1&trigger.repeatCount=0" />
<bean ref="myProcessor" method="myMethod" />
</route>
</camelContext>
My issue is when I try to starting the karaf container and postgresql is stopped, I have the log problem below and the camelContext "myCamelContext" will be shutdown.
It's possible to create route that call camel-quartz but the database is unreachable ?

I want to test camel spring integration example from the apache camel site
http://camel.apache.org/springintegration.html but I am getting the exception
org.apache.camel.RuntimeCamelException: org.springframework.integration.MessageDeliveryException: Dispatcher has no subscribers for channel outputchannel.
my short code is given below:
<channel id="inChannel"/>
<channel id="outputChannel"/>
<beans:bean id="greeting" class="com.javarticles.spring.integration.Greeting"/>
<service-activator input-channel="inChannel" ref="greeting" method="sayHello" output-channel="outputChannel"/>
<camelContext id="camel" xmlns="http://camel.apache.org/schema/spring">
<route>
<from uri="activemq:activemqsource"/>
<to uri="log:input"/>
<to uri="spring-integration:inChannel? inputChannel=outputChannel"/>
<to uri="log:output"/>
</route>
I tried to search related problems but I did not get with camel could any one tell me how to subscribe the outputchannel
According to the Camel documentation mentioned by you, the config should be like this:
<to uri="spring-integration:inputChannel?inOut=true&inputChannel=outputChannel"/>
Your issue is inOut=true:
The exchange pattern that the Spring integration endpoint should use. If inOut=true then a reply channel is expected, either from the Spring Integration Message header or configured on the endpoint.
