ProducerTemplate ... why no asyncSendBodyAndHeader(s)?

[Mike Oxford]

asyncRequestBodyAndHeaders exists ...
sendBodyAndHeaders exists...

Why no asyncSendBodyAndHeaders?

Thanks!

SendBodyAndProperties

[Mike Oxford]

There is a "SendBodyAndProperty" (singular.)
This is a "SendBodyAndHeader" (plural)

Why is there no plural version of the properties?

Jackson question... why does this fail?

[Mike Oxford]

...

   // mina component
   // unmarshal it
  // marshal it


I can put a bean:myBean in between and see that, yes, it is being
unmarshalled correctly.  Even more complex JSON will unmarshall correctly,
and I can traverse the returned Map.

{"a":5} // input
[B@73207f36  // output

Why does the  call return crap (an object ref of some kind?) even
for simple calls?

Thanks,

Jackson/JSON unmarshall

[Mike Oxford]

Hi all.

Given that you can use Jackson to unmarshall to "unmarshalTypeName="
(which works for a 1:1 mapping) how does one go about "dynamically
unmarshalling" a JSON document to "N-possible classes?"
eg, full protocol work, based on a piece of the JSON itself.

I can build something using the java DSL, or letting Jackson unmarshal
to a Map and then building POJOs by hand, but I'm wondering if there's
a better way, ideally, using the Spring XML syntax.

Something like ..







This way I can use a bean to determine which class to map the JSON to,
instead of hardcoding to a single class.

Thanks,

Re: New Instance of CamelContext from Spring

[Mike Oxford]

In Spring, you can set the scope='prototype' on a bean to stop it from
being, effectively, a singleton.
The same may work for your context, but I am not sure.

G'luck.

Re: Dynamic xsl with custom uri resolver

[Mike Oxford]

The CSS which is loaded is defined in your HTML.  If you're going to use a
parameter to fetch the HTML, you're going to have to dynamically rewrite
that HTML to point to the correct CSS.

Whether you use a handler to rewrite where to get the CSS file, or whether
it shoves all the CSS into the HTML and just delivers that ... either way
you're going to end up modifying the document delivered.

Or you'll have to create a lot of duplicates and de-normalize everything
... which works just fine until you make a change and have to update 50
documents.  =)

Or you write some javascript which looks at the document.URL, figures out
what CSS it needs, and then dynamically loads those files after the fact.
 Could be doable if you kept it sync so the JS blocks page render until
it's done with the CSS loading.

Pick yer poison...

Re: Conceptual understanding of altering routes runtime

[Mike Oxford]

I believe you can "synthesize" with a dynamic-router.

Get first chunk, route to processor-route.  When that route completes, it
will head back to dynamic-router with the same Exchange.  If that Exchange
has a property which says "this SQL connection" and a property which says
"this starting number" (or, if you have the handle to the SQL connection,
using a cursor) it may work for you.

G'luck...
