Saliya and Asankha,
I disagree here, note that these two modes handle two different scopes
of the scripts. Yes, it is possible to add a script with functions in
the inline scripting case, but this mode is rather expected to be used
in very simple mediation. In that case you do not have functions
declared inside the script but it is just a set of statements to be
executed.
If the concept is to facilitate simple scripts (i.e. without methods) in
the inlined case and support any sort of a script in the external case
then that's fine. Anyway it's useless to have an Inlined script with
several methods if you want to execute just one of them. However, if the
user provides an Inlined script where the outside code invokes a
function in the same script then it will work, won't it?
Anyway I think it'll be great if we can put a line into the
documentation saying that Inlined scripts are ought to be simple where
as external ones may be complex and can be reused.
Thanks
Saliya
In contrast, if you look at the referred external script then it is
more or less a set of functions and the main function that you need to
invoke has to be specified and this defaults to "mediate" if not
specified. In order to understand this in detail, you may have a look
at the invokeScript method of the ScriptMediator class in which you
call mediateWithExternalScript if the script is external and if the
script is inline it just executes the statements in the specified
order which is evaluated in the method mediateForInlineScript.
I suppose this separation is good an provides a simple mediation
approach as well as a complex mediation approach if required.
Thanks,
Ruwan

If I remember correctly, if you do not specify the name of the
function, we look for a function named "mediate".. However, I
agree with your view that we should execute anything outside the
functions.. we also need someone to take the Script mediator to
support JDK 1.6 :-) !

Hi all,
I am bit new to the script mediator. The synapse configuration
language mentions that we can define the which function to be
executed in the script if the script already exists (i.e.
referred by a key). The script can also be inlined according to
the document, but in this case it doesn't mention how can we
specify which function to be executed. If the script doesn't
contain any functions then executing the inlined script makes
sense, but if there are functions and the script is inlined then
executing the script means to execute anything outside the
functions isn't it? This is the same behavior in Rhino [1] when
you try to execute a JavaScript containing functions.
If my argument is wrong please correct me and let me know how to
specify the function to be executed when the script is inlined.
Thanks in advance,
Saliya
