Design Question With "Transformers"

[nhcoder <an...@hotmail.com>]

Hi everyone,

I am putting together a service assembly and while I have an example
working, I wanted to ask the experts as to if it was the best way to achieve
the goal. 

Basically what I have right now is a Static Routing Slip that has three
components in the flow of operations.  The first one accepts and processes
the xml message, then sends that to another component that calls a jms
queue, and then a third service unit post processes the message which then
gets returned to the calling client.

In this case my pre and post processing components are basically acting like
a Mule transformer.  Is this the right way to do this type of operation or
does ServiceMix have a "transformer" like component that you configure in a
different way in some config file?

Thanks,

Andy

Andy,

Using a static routing slip is perfectly fine for your use case.  We
don't really have a more specific concept like the Mule transformer
around because we could already handle the use case with the plain
EIP, I guess.

If you want a less verbose way to configure the same thing, you might
want to take a look at servicemix-camel too.  In the Spring XML
syntax, it would basically look like:
<route>
  <from uri="[starting-endpoint]"/>
  <to uri="[pre-processing-endpoint]"/>
  <to uri="[jms-endpoint]"/>
  <to uri="[post-processing-endpoint]"/>
</route>

You could also use the Java fluent API (my personal favorite) that
would read from(...).to(...).to(...).to(...).
