base class for context component?
Hi,
I'm trying to build my own context component as described in
http://camel.apache.org/context.html.
I wonder if there is a base class or interface I can use for
MyContextComponent. I saw there exists org.apache.camel.Component. But
the method createEndpoint() I have to implement does not make sense for
a context component.
Is there a better interface for this? Or should i create my own class
without interface?
Thanks,
Sven Bauhan

Sven did you see the test[1] that the snippet is from?
I still wonder if this is what you need, but if you're sure then try to
adapt that test to your application.
The test creates the JNDIRegistry but usually this comes from somewhere
else in the app, and as the docs say you can use JNDI, Spring, Guice or
OSGi etc
Just add this to your registry whatever that is and use the blackbox like
any other endpoint, hiding the details from the caller.

I did not mean to create a new implementation of DefaultCamelContext. I
want to create a class for a context component.

This is the code snippet I was talking about. For me it is not an
example cause I cannot copy it in a .java file and compile it. There is
no class or method definition.

Ok, I try to explain what I mean.
First I defined my context component route:
package de.dfs.com.atsm;
import org.apache.camel.ExchangePattern;
import org.apache.camel.builder.RouteBuilder;
import org.apache.camel.model.dataformat.JaxbDataFormat;
public class ContextRouteBuilder extends RouteBuilder {
public void configure() {
JaxbDataFormat jaxb = new JaxbDataFormat();
jaxb.setContextPath("de.dfs.com.atsm");
BeanToMSG atsm_process = new BeanToMSG();
Aggregation aggregation = new Aggregation();
from("direct:segment-in")
.unmarshal(jaxb)
.process(atsm_process)
.aggregate(header("ATSM-MID"),
aggregation).completionPredicate(aggregation)
.to("direct:message-out");
}
}
With this I try to make a context component like in the code snippet above:
package de.dfs.com.atsm;
import org.apache.camel.impl.DefaultCamelContext;
import org.apache.camel.impl.JndiRegistry;
public class ContextComponent {
private JndiRegistry m_registry;
private DefaultCamelContext atsm_context;
public ContextComponent( JndiRegistry registry ) throws Exception {
this.m_registry = registry;
this.atsm_context = new DefaultCamelContext(this.m_registry);
this.atsm_context.setName("ATSM");
this.atsm_context.addRoutes(new ContextRouteBuilder());
this.atsm_context.start();
this.m_registry.bind("atsm", this.atsm_context);
}
}
With this context component in the library I want to create an application:
package de.dfs.atciss;
import org.apache.camel.CamelContext;
import org.apache.camel.impl.DefaultCamelContext;
import org.apache.camel.impl.JndiRegistry;
import org.apache.camel.main.Main;
import org.apache.camel.util.jndi.JndiContext;
import de.dfs.com.atsm.ContextComponent;
import de.dfs.com.atsm.ContextRouteBuilder;
public class MainApp {
public static void main(String... args) throws Exception {
// Main main = new Main();
// main.enableHangupSupport();
// DefaultCamelContext atsm_context = new DefaultCamelContext();
// atsm_context.setName("ATSM");
// atsm_context.addRoutes(new ContextRouteBuilder());
// atsm_context.start();
// main.bind("atsm", atsm_context);
// main.addRouteBuilder(new ContextRouteBuilder());
// main.run(args);
JndiContext context = new JndiContext();
JndiRegistry registry = new JndiRegistry(context);
@SuppressWarnings("unused")
ContextComponent atsm_component = new ContextComponent(registry);
}
}
Here I fail, cause I don't know how to integrate my context component
into an application.
Can you explain, what to do?
Thanks, Sven
Re: base class for context component?
Posted by Taariq Levack <ta...@gmail.com>.
I got the idea that you really want to define an instance of the
DefaultCamelContext, and not the new class/implementation that you are
asking about.
And the docs you referred to discuss this, and it's the example for how to
do so. You can copy that sample and redefine it like this for example...
DefaultCamelContext fooBlackBox = new DefaultCamelContext(registry);
fooBlackBox.setName("fooBlackBox");
fooBlackBox.addRoutes(new RouteBuilder() {
@Override
public void configure() throws Exception {
// receive foo and forward to bar from("direct:foo").
to("direct:bar");
}
});
fooBlackBox.start();
registry.bind("someKey", fooBlackBox);
I hope I understood you, else lets try again starting with what you
want to accomplish.

Ok now you lost me completely.
I do not understand what you want to tell me.
Or did you just explain the source code in
http://camel.apache.org/context.html ?
I already understood the code snippets in this explanation. But what is
missing for me, is how I can put it in a running context.
Is there a small example that I could investigate to understand how it
works?
Thanks, Sven

Hi Sven
Perhaps you've misunderstood the following...
"Defining the context component"
In this context(excuse me), what's meant is a bean definition.
You should just use the DefaultCamelContext to define your own context,
with it's own name as this one is blackbox, and it's own routes.

No, you misunderstood me. I do not want to replace the Context Component
in Camel, but I need a class to define it. In the example the listing
shows just the definition of the route without class or method. My
questions concers the place for the definition of DefaultCamelContext.
Is there an interface definition for a class containing a context component?
Thanks, Sven

Actually Context Component is ready to use out of the box. You don't
need to create your own. Or if you have to, please share with us the
reasoning behind this need.
Best regards.
