Performance of Java Swing Vs Ajax ( Java Script )

We had developed application in swing which displays the data received after querying to web-service in Table and JTrees.
The current technological move is toward Ajax, It is ok that I can build this application in Ajax but not willing to go for replacment to swing.
I had following question, why should I go for Ajax over swing considering my type of application only ( beside plugins,JRE.. )?
And Peformance of Java script ( AJAX ) application over swing on following gorund?
1. Rendering of components in Swing & HTML ( browser )
2. Peformance of Java Script over Java ( CPU, Memory usage )
3. Event model in Java Script over java swing
4. Multitasking & Multithreading.
5. Storing data in variables.

The advantage of AJAX over Swing is clear, no special software is needed on a client computer other than an up to date browser.
Swing does have some advantages however in that it is much more established and there are many more tools available for developing a front end GUI application in Swing.
I have yet to find what I consider a "good" IDE for Javascript development on multiple platforms, Eg. IE, Firefox, etc...
Javascript is also not truly object oriented and that makes organizing your code and your design harder.
Performance I feel is a moot point between the two as it would hardly be noticeable, however I would guess that Javascript might have less performance than Java.

Java/java script auto generate END Date

Hi,
I have a jps page with 4 fields.
1. drop down list
2. text box
3. start date
4. end date
the problem is
text box will allow "number of days"
start date will get date from user on popup window
end date has to be generate based on text box value "no of days", another filed which will retrieve from db and start date
ex:
if text box values is <50 and start date (user selected date) is 02-04-2010 , the end date should add 8 days from the start date.
now the problem is calculating end date based on the start date with no of days which is given by user.
i have spend time to write java script, but i am not able to complete the entire logic.
please give some idea whether it can perform by java script or java bean.
Thanks,
Jasmin Rosline

now the problem is calculating end date based on the start date with no of days which is given by user.
Use the following code if you want to calculate in client side;
<html>
<script>
function addVal(){
var d = new Date(document.getElementById('dt').value);
d.setDate(d.getDate() +eval(document.getElementById('dd').value));
document.getElementById('result').value = (d.getMonth() +1) +"/" + d.getDate() + "/" + d.getFullYear(); }
</script>
<body>
<input type="text" id="dt" value="02/03/2011"/><br>
<input type="text" id="dd"/><br>
<input type="text" id="result"><br>
<input type="button" value="add" onclick="addVal()"/>

Display pop ups in the jsp by using Java script

Hi
can any body say ,how to display pop ups in the jsp by using Java script ?

that's correct. You can use the below code for AJAX request.
<script type="text/javascript">
var httpObject = getHTTPObject();
//create XMLHttpRequest object
function getHTTPObject() {
     var xmlhttp;
     if (window.XMLHttpRequest) // if Mozilla, Safari etc
          xmlhttp = new XMLHttpRequest();
     else if (window.ActiveXObject){ // if IE
          try {
               xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");
          catch ( e ){
               try{
                    xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
               catch ( e ){}
     return xmlhttp;
//define the function to send the request
function sendRequest(){
    var currDesc = document.getElementById("description").value;
    var URL = "manageMaintAction.do"; //action mapping in your struts-config
    var queryString = "currDesc="+escape(currDesc); //get the currDesc value in your action class like request.getParameter("currDesc")
    httpObject.open( "Post", URL, true );
    httpObject.onreadystatechange = cbFn;
    httpObject.setRequestHeader( "Content-Type", "application/x-www-form-urlencoded");
    httpObject.send(queryString);
//callback fn
function cbFn() {
    if (httpObject.readyState == 4)
         if (httpObject.status == 200)
          var result = httpObject.responseText;
          alert(result);

Best practice for java script placement on a BC page?

Hi guys just a general ask about where the best place for java script is on a BC page.
I just watched the this very good video on optimization http://bcgurus.com/tutorials/how-to-do-website-performance-optimization and in it it says how you should try and load the scripts at the bottom of the page so that it loads quicker.
now I want to do this but with it being a BC site i dont know if certain scripts have to be in the head of the doc. For instance the validate script I have? Does anyone know what I can and cant move from the head?
I was going to do what kiyuco like to practice and add all my scripts to a content holder and then add that to my pages/templates. Will BC like me adding this to the bottom of the page and not the head?
Thanks
Dave

Not only does Adobe flashplayer continue to crash on my operating system (windows 7) but now java script is having issues .... what is wrong with firefox????

for months I have checked the forums, and seen the same issues with Adobe Flash Player ... I have uninstalled and reinstalled too many times now and am totally frustrated with Firefox,. I just get it working again and Firefox updates and then I have the same issues ... and now my java script is screwing up and it never did before .... this all came after the latest update .... is anyone else having these issues or is my operating system under attack???

Recent crashes of certain multimedia contents (this includes Youtube videos, certain flash games and other applications) in conjunction with Firefox are most probably caused by a recent Flash 11.3 update and/or a malfunctioning Real Player browser plugin.
In order to remedy the problem, please perform the steps mentioned in these Knowledge Base articles:
[[Flash Plugin - Keep it up to date and troubleshoot problems]]
[[Flash 11.3 crashes]]
[[Flash 11.3 doesn't load video in Firefox]]

Java script created in Adobe Acrobat not working in Reader

Hello,
This is my first post, so I hope I chose the correct path for it
Let's get to the point:
I created a java script in Adobe Acrobat according to your tutorial page:
search.matchCase = false;
search.wordMatching = "BooleanQuery";
search.bookmarks = false;
search.query("Mytxt","Folder","../My directory");
which I found to be working as a let's call it a relative link, beacuse, after copying my file into another folder it would still work. But when I opened the same file in Adobe Reader I got a Console message:
Acrobat EScript Built-in Functions Version 10.0
Acrobat SOAP 10.0
GeneralError: Operation failed.
Search.query:4:Link undefined:Mouse Up
Folder does not exist
As I mentioned before the same file does return the results of the search.query in this folder in Acrobat. Any ideas? Suggestions? What might be the problem?

Thanks to your suggestion I started digging into the directories, so here's what's funny:
Title Page - main folder
Page 1 - sub folder
Searched PDFs - sub sub folder
I open the Title Page, then using a bookmark I open a new file in the same window: Page 1. There i have site links that allow me to perform search.query()
And now to the funny part:
In Acrobat:
If I open the "Title Page" and from there go to Page 1 my directory has to be:
../Main Folder/Sub Folder/Sub Sub Folder
to perform the required search
However If I open the "Page 1" manually my directory for the same java script has to be:
../Sub Folder/Sub Sub Folder
otherwise I get an error.
Anyway
Both don't seem to work in Reader....

How to refer an application item in a java script ?

Hi Friends,
I have a simple java script for disabling an item as below :
<script language="JavaScript1.1" type="text/javascript">
    function disFormItems(item1)
      if ($x(item1).value != "")
          disItem = document.getElementById(item1);
                disItem.style.background = 'beige';
                disItem.readOnly = true;
</script>I have an application level item G_BUTTON_FLAG. Based on the value coming into this application item I want to disable the item.
So I went and changed the script as below :
<script language="JavaScript1.1" type="text/javascript">
    function disFormItems(item1)
      if ($x(item1).value != "" && $x('G_BUTTON_FLAG').value == "EDIT")
          disItem = document.getElementById(item1);
                disItem.style.background = 'beige';
                disItem.readOnly = true;
</script>Can any one please tell me what am I doing wrong here ?
Thanks,
Raj.

Hi Teku,
Javascript can only see what is actually on the page - this has nothing to do with Apex, it's just what javascript is designed to do.
There are two things you can do:
1 - Add a hidden item to your page and set the application item as its source and then refer to that hidden item instead
2 - Use Ajax to get the value
I'd go with the first one as it's the simplest solution.

Java script with java

sir i have seen that java 1.6 mustang version is supporrting java script
if it is so please any one can help me on how to make my JEditorPane
to support java script
not only to jEditorPane but to any other swings component
i tried in all ways please can any one give me this help

Hello Farhan,
The OP stated that there is no condition on the process. In this case, I believe only 'SUBMIT' will cause the process to be fired.
"you can put anything in the string of the doSubmit."Well, you can do that, but it will have an effect only if you are using the REQUEST variable to condition a process. Otherwise, nothing will happen, and you want even receive an error message, because no error actually exist (as I believe happened with the OP case).

Arie.

URL Branch with java script target fails, but works as button press

I have a java script that displays a "report is loading" message when the page's submit button is pressed via the optional URL redirect attribute of the button.
Unfortunately, I had to remove the optional URL Redirect so that I could perform some computations and processes as a result of the button press.
I tried to put the script link in a branch attached to the button, but it failed with the following error.
ERR-1777: Page 11 provided no page to branch to. Please report this error to your application administrator.
Restart Application
After the branch to the java script, there is an unconditional branch to page 11.
Any one encounter this issue before and, if so, is there a work around?

Hi
Can you not use a URL redirect on the button to call your Javascript function - the Javascript will display the message you want to display, then call
doSubmit('request_name');
...to submit your page, picking up all your processes/computations etc
You then need to define a branch on your page which is conditional on the value of REQUEST - in this case request would be 'request_name'.

Java Script in PeopleSoft

Hello Folks,
I am new to PeopleSoft. I would like to know what are the scenarios to use Java Script in PeopleSoft (PeopleCode) and why to use java script when we have peoplecode?
Thanks!

Hello All,
Peoplecode is used to perform business logic checks for your application while javascript is used for client side validation.
So there could be situations where you can use the Peoplecode and Javascript.
Lets take an example :
Suppose you have feild on a peoplesoft page and the check is that the value entered in this feild should not be greater than 100.
Using Peoplecode this check can be implemented on feild change event, Which will execute on the server and will take processing time.
Using Javascript it can be done very fast without making any call to server.
So its better to use javascript in this situation.
Hope it clearifies your answer.
I would be providing a detailed post on the same at [http://peoplesoftnet.com]
Regards,
Anand
