Hi,
You need not add entire BlazeDS war file. You just have to
include the required jar files of BlazeDS, all the jar files in
WEB-INF/lib folder of the BlazeDS war are the required files to be
added into your web application. Also you need to create a folder
WEB-INF/flex in your web application and create services-config.xml
and other configuration files as in WEB-INF/flex folder in the
BlazeDS war file.
Regarding the path to your services-config.xml. This file is
compiled into your Flex application when you compile it. If you can
look at the compiler arguments of your Flex project you can find
the path to the services-config.xml.
If you want you can create the services-config.xml file in
any location and point to it in the compiler arguments. If you do
this make sure the end point URLs are hard coded in the
services-config.xml are proper and also there should be one
services-config.xml file in the WEB-INF/flex folder of your web
application for the BlazeDS/LCDS to use it to open up ports.
When you point to your web applications root directory for
the Flex builder, Flex Builder will use this location to load the
services-config.xml and when you give the context-root etc, these
will be used to replace the tokens in curls bracket in your
services-config.xml so that the URL to send a request to your web
application is formed based on the data you entered in the new
project dialogue of Flex Builder.
Hope this helps.
