How to Give any java application as a end point in from (....)
Hi,
Am Novice to Camel.
I had a java application which continuously produces the messages, i can get
this messages by implementing the one of the method [getMEssages()] in my
main class , my code looks like below
public class StandAloneCameClass implements MessageProducer {
public static void main(String args[]) throws Exception {
CamelContext context = new DefaultCamelContext();
context.addRoutes(new RouteBuilder() {
@Override
public void configure() throws Exception {
from(?????????????).process(MyProcessorInstance);
}
});
context.start();
Thread.sleep(10000);
context.stop();
}
@Override
public void getMessages(String s) throws Exception {
// here am getting/received messages , which need to pass
// to processor
}
}
I want to make this getMessages() as endpoint and need to pass this in from
(??????????) .
can some one guide me on this , how should i proceed ?

In a SOA-based solution, the middleware implemented by Camel would expose a
service over a standard transport/protocol like HTTP (SOAP or REST), JMS,
TCP, etc. This interface would ideally be driven by a contract.
Your producer application would then send messages via this transport to
the Camel-based integration middleware.
This is what I recommend, rather than binding the original application to
the Camel APIs. We offer 120+ adapters in the form of Camel Components to
build external interfaces, so you have huge variety to build the least
costly, most optimal communication channel in all cases.

A simplified answer is that the seda queue is defined when you use it as a
from endpoint ie from("seda:start").
To send messages to it in your example simply use the producer template
just change so the message is send to the seda uri instead of the direct.

Thanks Pontus Ullgren ,
can you explain something about seda implementation, i go to url but am not
able to get much,
want to know how we define seda que and put the messages to it ? in my

If you want to call the camel route synchronously then you can use a direct
endpoint[1] and then in getMessage() use a producer template[2].
Other options are to use a seda[3] endpoint.
So something like this:
public class StandAloneCameClass implements MessageProducer {
ProducerTemplate template;
public static void main(String args[]) throws Exception {
CamelContext context = new DefaultCamelContext();
context.addRoutes(new RouteBuilder() {
@Override
public void configure() throws Exception {
from("direct:start").process(
MyProcessorInstance);
}
});
template = context.createProducerTemplate();
context.start();
Thread.sleep(10000);
context.stop();
}
@Override
public void getMessages(String s) throws Exception {
// here am getting/received messages , which need to pass
// to processor
template.sendBody("direct:start", s);
}
}

[2] http://camel.apache.org/producertemplate.html
[3] http://camel.apache.org/seda.html

getMessage() is called by the java application contiously , where it insert
the messages coniniously
