Camel 2.0 - default endpoint
Hi
I am wondering if this "default" endpoint is used by anyone? I am
wondering what the purpose really is and what it solves. Is it
possible to consider to remove this?
Would remove many methods for ProducerTemplate so less for end users
to get confused by.

James that is a perfect example. The annotation and producer template
makes 1+1=3.
So let's keep it as is.

So I'm cool with removing the defaultEndpointUri from the CamelContext
btw - creating a default ProducerTemplate without specifying a default
endpoint URI could just barf if you tried to send to the default
endpoint.
However having a default endpoint URI on a ProducerTemplate is a good
thing; it lets folks send messages without having to worry, in their
Java code - of specifying where it goes unless they want to mediate
between multiple endpoints which they know about.
e.g.
public class MyFoo {
@Produce(ref="someEndpoint")
ProducerTemplate template;
...
template.sendBody("<hello>world!</hello>/>");
you then don't have to inject 2 objects; one the URI/endpoint and one
the producer.

Sorry the smiley faced the wrong direction. Should be ;)
I am not at all sour, even though my mail might have such a tone. Just
me being curious and digging into all kind of corners in Camel
and being from Denmark where we tend to raise our voices.

Re: [DISCUSS] Camel 2.0 - default endpoint
Posted by Claus Ibsen <cl...@gmail.com>.
Hi
Thanks for the explanation. But What I am raising a voice for is the
Camel entry level users. When they start to use ProducerTemplate they
get a long list of methods. So it can be confusing which method to
use. Just to eplain the difference between sendXXX and requestXXX is
quite "hard enought". So having this 3rd option that is very rarely
used is on option I would like to eliminate.
I have yet to see any documentation, end users requesting about it,
unit test etc that uses this feature.
There are 5 methods with the default thingy
There are 8 methods with send
There are 12 methods with sendBody
There are 2 methods with request
There are 6 methods with requestBody
A total of: 33 methods.
But I will turn my attention to other issues to tackle ;(

Re: [DISCUSS] Camel 2.0 - default endpoint
Posted by Hiram Chirino <hi...@hiramchirino.com>.
The idea is that in Dependency Injection scenario is it's simpler to 1
inject one thing (the template) into another object rather than 2
things (the object and the endpoint).
It's an ease of use issue. And camel is all about ease of use.
Is this really complicating things that much? I would think there are
tougher issues to tackle.

Re: [DISCUSS] Camel 2.0 - default endpoint
Posted by Claus Ibsen <cl...@gmail.com>.
Hi
I guess the endpoint resolution can be done once. So I still don't see
the valid point of this default
final Endpoint ep = context.getEndpoint("uri");
ProducerTemplate template = new DefaultTemplate(context);
while (condition) {
template.send(ep, body);
}

Re: [DISCUSS] Camel 2.0 - default endpoint
Posted by Hadrian Zbarcea <hz...@gmail.com>.
I think the point is that you can have something like:
ProducerTemplate template = new DefaultTemplate(context, uri);
while (condition) {
template.send(body);
}
This would work too, of course:
ProducerTemplate template = new DefaultTemplate(context);
while (condition) {
template.send(uri, body);
}
... but it would force an endpoint resolution at every iteration.

Re: [DISCUSS] Camel 2.0 - default endpoint
Posted by Claus Ibsen <cl...@gmail.com>.
Hi
Hmm is there any documentation with such a sample how to reuse it?
I would still like to keep Camel simpler and not support "corner case
use-cases", that is not documented or anyhow possible for end-users to
figure out how to use.
We could maybe reduce some of the default endpoint send/request
methods on ProducerTemplate to reduce the number of methods end-users
get when they press control + space. If we could keep one for these
few uses-cases with reuse?

I just talked to Hiram to figure out why it got there in the first
place. He gives a
-1 for removing,
and I change my vote to 0 :). The idea comes from the spring jms
template and it's quite handy when you want to reuse the template and
keep sending to the same uri. The endpoint uri resolves once. Well,
I can see it's usefulness. I'd say let's keep it.
More opinions welcome,

I've never used this, nor could I imagine when I'd ever want to use it.
+1 for removing

[DISCUSS] Camel 2.0 - default endpoint
Posted by Hadrian Zbarcea <hz...@gmail.com>.
Hi Claus,
Now I get it :). In any non trivial case it's useless and could be
confusing/error prone I agree.
I think it is there mostly for convenience for developers, so if we
take it out the inconvenience would be that they'd have to specify the
endpoint (uri) explicitly, which from my point of view is good.
A strong +1 from me on this, but I'd like another opinion too.
Cheers

Re: Camel 2.0 - default endpoint

Hi
Yes I did not make my point clear.
It's the fact that CamelContext requires a default endpoint URI to be
configured. Then you can use ProducerTemplate.sendBody("Hello World")
and then it will send this body the default endpoint URI. Normally you
have to provide the URI as well such as:
ProducerTemplate.sendBody("direct:in", Hello World");
The class DefaultEndpoint should of course be there as the base class ;)

Claus,
DefaultEndpoint is the base class for all Endpoints and provides a
default implementation of the Endpoint methods.
Am I misunderstanding your question?
