Basically I have several container lists - and lists within lists that
have numbers that need calculated based on whether certain boolean
fields (also contained in these containers) are true.
I want this calculation done every time the user selects a check box or
drop down on the screen that effects the calculation. I could of course
at JSP time send down all the data the javascript will need and do the
calculation client side. The problem is I already have the calculation
method in the back end and would prefer to use this rather than a
replicated javascript version. That way I am only maintaining one piece
of code. I also don't have to send down a large amount of JAVAScript to
the page.
This is where I figured AJAX could help. I've noticed in the Jahia code
base they use Struts actions and are able to get the ProcessingContext
and thus JahiaData inside AjaxAction.java. My concern is that I don't
really consider these the struts actions. I was going to create my own
class which didnt inherit from Action but I've noticed a call to
getServlet which is inherited from inside struts. Thus without using
this method currently employed by Jahia's codebase I don't see how I can
gain access to JahiaData. I don't really want to use the struts actions
methology because I don't like the idea of one class having one purpose
- ie the execute method. Instead I would like to create one class to act
as an AJAX interface to several of my methods on the back end. With the
current situation this would require a) seperate classes for each method
call I want to use or b) a parameter which customises which part of the
execute method which gets called. Neither a) or b) appeal to me.
Thanks,
Richard.

hi richard,
i'm not very sure to understand why you need to make an ajax call to
calculate sum's result from différent container lists.
i presume you can obtain this within a scriptlet using the jahia api
with the methods like getContainerList and getAbsoluteContainerlist,
and iterate through all these containers(and fields's values?) and
make your computing processes as u need?
for your 2nd question, there is no simple way to transfer from
javascript a java object (like jData).
Usually, in an ajax requests, you can send only unique references or
ids as parameter.
this way, server-side, the class in charge, can get the object(s) and
respond successfully to the request.

Hi all,
I have an AJAX method that runs through some containers lists and
calculates totals. I need jData to make the getAbsoluteContainerList
call.
I can access the jData object through <%=jData%> from inside the JSP.
I want to pass this to my AJAX method but i'm not even sure if thats
possible.
Alternatively I would like to get the jData object from within my
class. I don't have access to ProcessingContext from here. Is this
possible?
Thanks,
Richard.
