Note that we don't
recommend having a JSP build up your data into a SWF unless it won't change
very often as the re-compilation per-user is very expensive.

Flex/Flash components Server-sid e?
Tracy,
Another
idea is to do server side processing in a jsp page using the mxml tag
library. The jsp source can use the mxml tag library and generate mxml
code dynamically in java. Using this approach your java code can access
your back end resources do complex calculations/analysis and build the data
directly into mxml code. The tag library builds the generated mxml code
into a swf and returns it to the client. A jsp request has to return a
full swf instead of a component. It's an interesting idea to think about
a jsp returning a component instead of an mx:Application.
So the
client might request:
processReport.jsp?queryParam=param1&queryParam2=param2 (or pass
parameters as POST)
The jsp
may have code like:
processReport.jsp:
<%@
taglib uri="FlexTagLib" prefix="mm" %>
<mm:mxml>
<mx:Application xmlns:mx=http://www.macromedia.com/2003/mxml>
<mx:Array id="dp0">
<%= buildTableData() %>
</mx:Array>
<mx:DataGrid dataProvider="{dp0}" />
</mx:Application>
</mm:mxml>
So your
buildTableData method is just a java method which processes the data on
the server in java then returns a string with the format of
<mx:Object param1="name1" param2="name2" /> for each datagrid
row. So client downloads the processed data and does not have do the
work on the client (and in actionscript).
Or
instead of generating object data as a dataprovider from java methods you
could generate normal mxml tags populated with the data.
Also
when building some applications I have written java http services which call
web services and process the data instead of making the client do additional
calculations.

Thanks,
Since
duplicating my AS logic in another language is not practical, I will justhave
to pull everything down to the client for my batch
operations.
I'm not
completely giving up on this idea, though. Maybe a server-side piece
could impersonate a client and access the flex on a second
server....
Thanks,
guys.

Of
course, your components would then have to be implemented as Java rather than
ActionScript.

No, Flex
components aren't meant to be run on the server. This sounds like you
might have a use-case for writing true server-side logic that you would then
call via RemoteObject (or WebServices).

Subject: [flexcoders] Possible to use
Flex/Flash components Server-side?
Say I have very
complex, faceless mxml components (that do data
service access, validation, caluclation, analysis, etc)
that usually
are accessed via a
flex UI in the normal fashion.
But sometimes, I want to change the data underneath several
of them,
initiate the processing,
and simply return single values to some
master administration UI.
Is it possible to programatically instantiate an initialize
flex
components a the (some?)
server, and return only the single value?
Sort of making flex components work like a web service or
Java
servlet themselves? And
accessing via remoting or some such?
This would be for an intranet-type application, so server
load would
be
manageable.
Any ideas?
Directed rtfm?
TIA!
