Passing variable from javascript to servlet!!!

Hi all,
I have one doubt,

In Brief,
i am getting some values in javascript through jsp and the same values i
want to use in servlet.
Yes, i know i can get these values in servlet by using request.getParameter("");
But these values are dynamically generated so i dont know how many varaible are they!. so i am trying to put some array list so that i can forward this values to servlet.
But i can't get this array which is declared in javascript!! :( so any buddy can help me how to get this dynamically generated values in servlet!!!

Passing Parameter from javascript to Servlet

hi,
I have 2 list boxes in my Jsp page and values for these list boxes are preloaded . These things are to be carried out using javascript onload() function.
So now i want to pass the selected parameters from both the list boxes to servlet and have to display the corresponding resulting datas in same JSP page. if i submit the form then values selelcted by the user will reset because the form has onload() function. then i thought hidden field will solve my problem. but its giving error like nullpointer exception.
so please tell me how to achive this.

When you right a new Option(...) line in javascript, there are three parameters you can give:
Option("text", "value", selected);
How you make use of this depends on how you move from the servlet back to the JSP.
So for example, if you are doing a response.sendRedirect in the servlet, you will either have to add a parameter back to the url you are re-directing to, or add the value to the session. (I like the session method myself... hides it from the user)
//in servlet
public void doGet(...)... {
    String country = request.getParameter("country");
    String state = request.getParameter("state");
    //... Do Stuff ...
    HttpSession session session = request.getSession();
    session.setAttribute("country", country);
    session.setAttribute("state", state);
    String sendTo = response.encodeRedirectURL("theForm.jsp");
    response.sendRedirect(sendTo);
//... The JSP might look like this now...
//Get the selected values from the session:
<%
    String countrySelected = (String)session.getAttribute("country");
    String stateSelected = (String)session.getAttribute("state");
%>
<html>
<head>
<script type="text/javascript">
/* Use this to store the values for states in JavaScript */
var state2DArray;

Passing variables from one swf to another

I am facing problem to pass variable from one swf to another.
I am using loadMovie to load another swf. how can I pass a variable
value to another swf. Can anyone help me plz? It is somewhat
urgent.
thanx in advance.

first of all:
this is the Flash Media Server and your problem is not
related to FMS....
second thing related to the "somewhat urgent" :
we, users on this forum, are not there to do your job... so
calm down otherwise no people will answer your question. This forum
is a free support forum that community of Flash developer use to
learn tricks and to solve problems.
Possibles solutions:
If the two swf are seperate you can use LocalConnection to
establish a connection between different swf.
If you load a second swf into the first one you can interact
like a standard movieClip(only if there from the same domain or if
you a policy file on the other server)
You can use SetVariable(via Javascript) to modify a root
variable on the other swf and check with an _root.onEnterFrame to
see if the variable had changed in the second swf.
* MovieClipLoader will do a better job, in your specify case,
than the loadMovie. Use the onLoadInit event to see when the swf is
really totaly loaded into the first one otherwise you will have
timing issues.
My final answer(lol) is the solution 2 with the

OBIEE 11g How to pass variable from one prompt to another prompt in dashboard page.

How to pass variable from one prompt to another prompt in dashboard page.
I have two prompt in dashboard page as below.
Reporttype
prompt: values(Accounting, Operational) Note: values stored as
presentation variable and they are not coming from table.
Date prompt values (Account_date, Operation_date)
Note:values are coming from dim_date table.
Now the task is When user select First
Prompt value “Accounting” Then in the
second prompt should display only Accounting_dates , if user select “operational”
and it should display only operation_dates in second prompt.
In order to solve this issue I made the
first prompt “Reporttype” values(Accounting, Operational) as presentation
values (custom specific values) and default presentation value is accounting.
In second prompt Date are coming from
dim_date table and I selected Sql results as shown below.
SELECT case when '@{Reporttype}'='Accounting'
then "Dates (Receipts)"."Acct Year"
else "Dates (Receipts)"."Ops
Year" End FROM "Receipts"
Issue: Presentation variable value is not
changing in sql when user select “operation” and second prompt always shows
acct year in second prompt.
For testing pupose I kept this presentation
variable in text object of dashboard and values are changing there, but not in
second prompt sql.
Please suggest the solution.

You will want to use the MoveClipLoader class (using its loadClip() and addListener() methods) rather than loadMovie so that you can wait for the file to load before you try to access anything in it. You can create an empty movieclip to load the swf into, and in that way the loaded file can be targeted using the empty movieclip instance name.

Passing data from JAVASCRIPT to SAP database

Hi Experts,
Is it possible to connect or access RFC function module through JAVASCRIPT? I want to send data from JAVASCRIPT to SAP database table.
Is it possible to pass data from JAVASCRIPT to SAP database table?
Thanks in advance.
Regards,
Arindam Samanta.

OData services can be one option to achieve this.
Another possibility can be use of Generic REST enablement with SAP NetWeaver Gateway.
If you are not considering Gateway at all, then A JSON adapter like the one mentioned in JSON Adapter for ABAP Function Modules can be handy.

Passing variable from one JSP to another

Hi....
I am working on customizing Oracle Application(istore).
I need to pass variable from 1 JSP to another.
JSP 1 contains the following line of code:
<INPUT type="HIDDEN" name="soldtoCustPartyName" value="<%=soldtoCustPartyName%>">
How can I pass this to another JSP Page. The other JSP should take the 'soldtoCustPartyName' and find out the primary address country.
So please help me in getting variable passed from 1st JSP to next.
By default, 1st JSP is not fwded to 2nd JSP.
This is very very urgent...Please help.....

When you push the submit button on jsp1 - it goes to jsp2?
ie
// in jsp1.jsp
<form action="jsp2.jsp">
<INPUT type="HIDDEN" name="soldtoCustPartyName" value="<%=soldtoCustPartyName%>">
<input type="submit">
</form>
//Then in jsp2.jsp all you need is
request.getParameter("soldtoCustPartyName");This will pick up the value that is coming from the hidden field on jsp1

Passing variables from php to flash and the opposite

Hi guys, im trying weeks now to solve this problem but nothing yet
If someone could just tell me how to pass variables from flash to php and the opposite i would be thankful!!! Please help!

I have recently had to learn this, so this may not be the best way but it worked for me
I suggest looking at the code below stripping out everything you don't need (e.g. the databse stuff) and just get a simple string going back and forward
have a go and post any problems here and I'll try and help
in flash i have
private function getBalanceAndXP():void
          var request:URLRequest = new URLRequest("utils.php");
          request.method = URLRequestMethod.POST;
          var variables:URLVariables = new URLVariables();
          variables.func = "getBalance";
          variables.fbid = userID;
          request.data = variables;

          loader.dataFormat = URLLoaderDataFormat.VARIABLES;

Passing variables from Applescript to bash

Hello,
I'm trying to pass variables from Applescript to bash using the following code
#!/bin/bash
osascript <<EOF
tell application "SystemUIServer"
set username to text returned of (display dialog "Enter your name" with icon caution default answer "" buttons{"Continue"})
set macname to text returned of (display dialog "Enter name of your Mac" with icon caution default answer "" buttons{"Continue"})
do shell script "export USERNAME=" & quoted form of username & " && export MACNAME=" & quoted form of macname
end tell
EOF
echo "USERNAME is $USERNAME, MACNAME is $MACNAME"
but no luck
Mac-mini:Downloads admin$./new.command
USERNAME is , MACNAME is
Any help would be greatly appreciated.

I just realized you are returning 2 variables. That can still be handled by echoing/printing the values, you just have to parse the output, or use other tricks.
VALUES=( $(osascript -e '...') )
This would make VALUES an array, with each array element containing one space separate return value from osascript
USERNAME=${VALUES[0]}
MACNAME=${VALUES[1]}
If USERNAME or MACNAME could have spaces in them, you would need to use some kind of separator character. For example if you use @ as the separator you could do something like:
VALUES=$(osascript -e '...')
USERNAME=${VALUES%@*}
MACNAME=${VALUES#*@}
which will %@* will delete everything starting with the @ til the end of the string, and #*@ will delete everything from the beginning of the upto and including the @.
Another trick is to have the return values be properly formed shell variable assignments such as
print "USERNAME='your user name' MACNAME='Your Mac Name' " -- I'm making this up as I do not really know Applescript, so you will have to figure out how to get Applescript to print something that looks like
USERNAME='your user name' MACNAME='Your Mac Name'
In your shell script you have code that looks like:
VALUES=$(osascript -e '...')
eval $VALUES
The eval will execute whatever is stored in $VALUES, and if that happens to look exactly like shell variable assignments, you get the variables created in the current shell context, where can use them.

BIG THANKS!!

the problem is nothing your showed.   did you see a security warning that you ignored?
to test, if that's the problem go here and adjust your security settings: http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager04a.ht ml
if that fails, upload your files to a server and confirm everything works. then start working on your local configuration.

Passing variables from Report to Form

Hi, I need pass a couple of variables from the REPORT to two fields in the FORM for save in a table. Somebody knows how do I do this?. Any suggestions?
Thanks a lot!
I think that this situation is different that pass variables from FORM to REPORT.

You need to use a Link component to your Form that you then attach to one of the data columns in the Report. When you edit the link in the report, you can specify the fields to pass.

How can I pass variables from one project to another using Javascript?

Hi all, I am trying to do this: let learners take one course and finish a quiz. Then based on their quiz scores, they will be sent to other differenct courses.
However, I wish keep track on their previous quiz scores as well as many other variables.
I found this nice widge of upload/download variables by CPguru (http://www.cpguru.com/2011/05/18/save-and-load-data-widget-for-adobe-captivate-4-and-adobe -captivate-5/). However, this widget works by storing variables from one project in local computer and then upload it to another project.
My targeted learners may not always use the same computer though, so using this widget seems not work.
All these courses resided in a local-made LMS which I don't have access to their code. Therefore, passing variables to PHP html files seems not work.
Based on my limited programing knowledge, I assume that using Javascript to pass variables may be the only possible way.
Can someone instruct me how to do this?
Thank you very much.

If you create two MIDlet in a midlet suite, it will display as you mentioned means you can't change the display style.
