Route to two paths
In a project I am working on, I am parsing a large excel file, and during the
routing, I am performing some validation on the data. I have a route that
performs the validation, and if validation is good, I want to continue down
the same routes that exist. But if the data is invalid, I want to pass it to
a different route to process and handle database writes there.
I have went through all the EIP patterns, but do not see one that performs
what I call a sift, where the good ones go down one path and the bad ones go
down a different path.
Can someone assist with possible work arounds for this?
Thanks
Scott

You could have a bean or processor check the data and set the next route in a header. Then use .toD after the bean/processor to send to the proper next step.

what about using a content bases router
http://camel.apache.org/content-based-router.html
http://camel.apache.org/why-can-i-not-use-when-or-otherwise-in-a-java-camel-route.html
Also take a look at the simple language for access to header and content information
http://camel.apache.org/simple.html

Set appropriate headers using .header("type",constant("good/bad"))
Then use the conditional operators to route accordingly..Something like.
.choice().when(header("type").isequalto("good")).to("direct:good").otherwise().to("direct:bad").end();

Re: Route to two paths

Ok I would like at generate a new message containing the good ones and a a
message for the bad ones. You can see here for how to generate a new
message.
http://camel.apache.org/how-do-i-write-a-custom-processor-which-sends-multiple-messages.html
Essentially you would have to create a list of good objects and set the
exchange body to that list and route it depending on the good or bad. You
can set the destination in a header. Then in the next step have the
.toD(<someheader>).

Re: Route to two paths
Posted by spurcell <sc...@mastercard.com>.
Tried coding a dynamicRouter, but not understanding how to set the exchange
for each different route.
Let me step back.
I have a list of Objects some good, some bad in my current exchange. So body
would be akin to the following:
A-GOOD
B-GOOD
C-GOOD
...
F-BAD
H-BAD
I-BAD
...
I want to take the good, create a new exchange, take the bad and create
another exchange and route the good and bad to different routes.
I do not want to use a splitter and have to reaggregate, and was hoping
there was a workaround for this scenario.
Googling has not found anything that would work. Dynamic routing
documentation is a bit confusing, and I don't know how to create 2 exchanges
with it.
Thanks,

There is also eips like routing slip and dynamic router.

I guess in that case you need to set the destination upon extracting the
list in a header and use the .toD() to do dynamic routing.

Our team is trying to avoid doing another split, choice aggregate due to
performance. In my current route, I can create a "good" list and a "bad"
list, so basically the tech lead wants me to take the elements from the good
list, send them to a specific route, and take the bad list and send them to
a different route. Basically doing more of a "custom" split, or something
more along that line.
