Christian Mueller commented on CAMEL-2761:
------------------------------------------
My proposal, which I discuss with Tom Fennelly:
Here are my first thoughts:
1) How could Camel improve Smooks? What do you have in mind?
2) How could Smooks improve Camel? Here are my ideas:
2a) Java Binding:
DataFormat smooksUnmarshal = new
SmooksDataFormat("smooks-unmarshal-config.xml");
from("file://inbox")
.unmarshal(smooksUnmarshal) // source is a StreamSource, result is a JavaResult
.to("bean:orderEntry");
We could do this for CSV, EDI, XML, fixed length, YAML and JSON, could we?
But what is with marshaling? My understanding is Smooks "only" supports
marshaling to XML. It is right? Do you plan also to support other formats like
CSV, fixed length, ...? Or "only" with templating?
We could also provide marshaling functionality for this:
DataFormat smooksMarshal = new SmooksDataFormat("smooks-marshal-config.xml");
from("bean:orderEntry")
.unmarshal(smooksMarshal) // source is a JavaSource, result is a StreamResult
.to("file://outbox");
Make this sense?
This is also the solution for the current camel-smooks component:
http://camel.apache.org/smooks.html
Please have a look on the attached SmooksDataFormat.java
2b) Transformation:
Could we express transformation as a sequence of unmarshal and marshal?
If not, I would propose a solution like the camel-xslt component:
http://camel.apache.org/xslt.html
Than we could write a route like this:
from("file://inbox")
.to("smooks://path/to/smooks-config.xml") // source is a StreamSource, result
is a StreamResult
.to("file://outbox");
or
Than we could write a route like this:
from("bean:orderEntry")
.to("smooks://path/to/smooks-config.xml") // source is a JavaSource, result is
a JavaResult
.to("bean:orderStore");
With this solution it's also possible to handle Java Binding (2a)). But we have
to know, what is the source we will receive (Java, Stream, ...) and what is the
result (Java, Stream, ...). It is possible to "ask" the Smooks instance for
that so that we know, which kind of source and result we have to provide in the
filterSource method?
What do you think?

Christian
