Calling a Jdialog from javascript using bean in JSP

Hello all...
In my jsp page , I have a button , onclicking it a javascript is called and in that javascript a bean is called to show a JDialog window. In that Jdialog window , I have a JTable, Accept button and Cancel Button..
But the JavaScript is not calling bean...
sample code :
<input type ="submit" name="submit" onclick="func()">
<script language ="javascript">
func(){
beanid.fn();
</script>
and in MyClass.fn(){
codes for display is written......
Is there anything wrong in this approach or if any other solution will to my needs please let me know..
Regards
SunilrKP

Where is the JavaBean? Are you using an (J)Applet to deploy the bean to the client? If so then you might want to hop on over to the [Applet Forum|http://forums.sun.com/forum.jspa?forumID=421] to see what the problem is. When you do, show them the JavaScript you use to access the Applet.
If you are not deploying the JavaBean via an Applet, then the class lives on the Server, while JavaScript lives on the Client - two different machines separated by space and time. You will need to change your approach (ie deploy the bean via an Applet or don't stop trying to use Swing as display over HTTP).

Calling a procedure from Javascript

Hello
I have created a procedure with two input paprameters.

Help with calling java functions from javascript

I am using javax.script to interpret javascript from a java applet. it loads the js file into a string, and then does engine.eval(script_string). My question is, how would I make functions in the class file that are available to javascript?
Update: Instead of that, I am loading a js script that will contain all of the usable functions. Here it is:
//core.js for Javasphere 0.31
var pkgs = new JavaImporter(java.lang, java.lang.System, java.awt);
with(pkgs) {
function Abort(msg) {
        var graph = new Graphics();
        g = graph.getgraphics();
        g.drawString(msg, 20, 20);
}When I do engine.eval("Abort(\"something\")"); it throws this error:
javax.script.ScriptException: sun.org.mozilla.javascript.internal.EvaluatorException: error instantiating (0): class java.awt.Graphics is interface or abstract (<Unknown source>#8) in <Unknown source> at line number 8

Eggbertx, let's start from scratch if you don't mind. Say you have this Applet
pubic class MyApplet extends Applet
String message;
//CALL THIS METHOD FROM JAVASCRIPT
public void setMessage(String msg)
    message = msg;
    // this saves you from having
    // to call getGraphics() from JavaScript
    repaint();
public void paint(Graphics g)
    g.drawString(message, 10, 30);
}Then in your HTML file you may have something like this:
<input type="text" id="msg" value=""></input>
<input type="button" value="Set Message" onclick="setAppletMessage()"></input>
<applet id="myApplet" code="MyApplet.class" width="400" height="100"></applet>And in the JavaScript file:function setAppletMessage()
var msg = document.getElementById("msg").value;
document.myApplet.setMessage(msg);
}This is about all you really need to do. See how the Graphics object is no longer in your .js file?
Note: You may run into other difficulties in getting this code to work because of browser, security, or some other pain-in-the-neck issues, but this is the idea.
Eggbertx, I see you added a star to my first post and I think you should take that off because:
1. <tt>Component</tt> is abstract... so you can not call the <tt>new</tt> operator.
2. The call <tt>component.getGraphics()</tt> is not going to work either, because <tt>component</tt> was never created.

How to call SOAP API from JavaScript

Hi,
I'm trying to call the SOAP API to get statistics about emails. Are there any examples on how to call the API from JavaScript?
Here is a link to my original question about using the REST API. REST API URL for email statistics
Thanks,
Tim

Tim,
In order to consume a SOAP API I recommend you use something other than JavaScript.
Any platform can offer you a good SOAP client should be OK. (.Net, Java, php, Ruby, python).
I didn't see anyone successfully used javascript and consume the Eloqua SOAP API.
I know you can create a SOAP client in Java script but it will be too much work to handle the Eloqua response in some cases.

Calling Java API from ABAP using JCo (Part 2)

Hello,
This is an additional question to thread Calling Java API from ABAP using JCo
Has anyone managed to get the input parameter value
input.getString("REQUTEXT")
that is being passed from ABAP?
If yes, what kind of setting you need to do? Because when I execute, it has no value.
Thus, the below ECHOTEXT parameter returns blank value:
output.setValue(input.getString("REQUTEXT"),"ECHOTEXT");
When I debug by printing the below line, the input XML is indeed without value:
System.out.println(input.toXML());
Anybody knows how to pass input variable from ABAP to JAVA using JCo?
rgs,
hiroshi

Hallo Hiroshi,
as far as I can see, you are doing it the right way. The problem might be that the ABAP program does not fill in this parameter because something went wrong in the SAP System.
Have you tried setting a breakpoint (an HTTP session - remote breakpoint) and tried checking step by step if the value is being processed and put into the REQUTEXT field?
Bye,

Call .xhtml file from javascript function

Hi,
Is there a way to call .xhtml page from javascript function???

BalusC wrote:
Yes there are some ways. But this question has nothing to do with JSF and certainly not with Java at all. Javascript is an entirely different language, although it has a similar syntax as Java (and unforunately also a similar name, they should never have renamed it from ECMAScript).I think ECMAScript is a renaming from JavaScript. The originally JavaScript was called LiveScript by Netscape. I've heard that the ECMAScript name was deliberately chosen to be unsexy.

Calling JavaFX Script from JavaScript on mobile

Hi,
We are developing a application which would run on a mobile. We have to call javafxscript from javascript in this application. Is there a way to do this on a mobile application. I am able to do this for application running on browsers.
Will javafx mobile application support this Calling JavaFX Script from JavaScript?
Please share any information related to this.
Regards,
Sherlyn

I doubt it (but I can be wrong!).
javafx.stage.AppletStageExtension is only on the desktop profile.
[Calling From JavaScript to JavaFX Script|http://javafx.com/docs/tutorials/javafx-javascript/] article states "+this functionality requires Java SE 6 Update 10 at minimum+" which seems incompatible with mobile usage.
Beside, a quick Google search hints that JavaScript support on mobile browsers is weak or inexistent (depending on browsers).

Call struts action from javascript?

Hi all
I'm having problem already discussed here quite a lot, but I have idea to solve it different way. And need to know is it possible or I'm doing mission impossible here :(
I have JSP with 2 drop down lilsts, where the second is populated according to selected value from first - that's basically my problem.
Is it possible to somehow only call my struts action which will return all needed values using javascript and onchange event handler?
I dont have any experience with javascript, and I'm trying to avoid it as much as possible at the moment.
Thanks in advance

Call Java Method From JavaScript Function

hi everyone
i need a help in calling Java method from a javaScript method
ex:
function confirmAddRecord() {
cHours =document.getElementById('frmP:ChargeHours').value;
cSTime =document.getElementById('frmP:ChargeStartTime').value;
var answer = confirm("Are you sure you want to add Record?")
if (answer){
here i want to call the Java Method that is located in session bean that takes the upper params cHours & cSTime
else{
return false;
i know i can do it as an action button but it is required me to be in that way can any one help plz

That depends on the nature of your parameters. I guess you calculate the params on client and then want to submit them. In this case and if you don't want to use Ajax simple add some <input type="hidden"> elements (of course there correspondend components dependent of your framework) and store the params there. If the javascript isn't invoked by a button click, you can use a button nevertheless. Set visible="false" and call
document.getElementById('client_id_of_my_hidden_button').click();
(or maybe doClick() dependent on your framework).

Call C# method from javascript in WebView and retrieve the return value

The issue I am facing is the following :
I want to call a C# method from the javascript in my WebView and get the result of this call in my javascript.
In an WPF Desktop application, it would not be an issue because a WebBrowser
(the equivalent of a webView) has a property ObjectForScripting to which we can assign a C# object containg the methods we want to call from the javascript.
In an Windows Store Application, it is slightly different because the WebView
only contains an event ScriptNotify to which we can subscribe like in the example below :
void MainPage_Loaded(object sender, RoutedEventArgs e)
this.webView.ScriptNotify += webView_ScriptNotify;
When the event ScriptNotify is raised by calling window.external.notify(parameter), the method webView_ScriptNotify is called with the parameter sent by the javascript :
function CallCSharp() {
var returnValue;
window.external.notify(parameter);
return returnValue;
private async void webView_ScriptNotify(object sender, NotifyEventArgs e)
var parameter = e.Value;
var result = DoSomerthing(parameter);
The issue is that the javascript only raise the event and doesn't wait for a return value or even for the end of the execution of webView_ScriptNotify().
A solution to this issue would be call a javascript function from the webView_ScriptNotify() to store the return value in a variable in the javascript and retrieve it after.
private async void webView_ScriptNotify(object sender, NotifyEventArgs e)
var parameter = e.Value;
var result = ReturnResult();
await this.webView.InvokeScriptAsync("CSharpCallResult", new string[] { result });
var result;
function CallCSharp() {
window.external.notify(parameter);
return result;
function CSharpCallResult(parameter){
result = parameter;
However this does not work correctly because the call to the CSharpResult function from the C# happens after the javascript has finished to execute the CallCSharp function. Indeed the
window.external.notify does not wait for the C# to finish to execute.
Do you have any solution to solve this issue ? It is quite strange that in a Window Store App it is not possible to get the return value of a call to a C# method from the javascript whereas it is not an issue in a WPF application.

I am not very familiar with the completion pattern and I could not find many things about it on Google, what is the principle? Unfortunately your solution of splitting my JS function does not work in my case. In my example my CallCSharp
function is called by another function which provides the parameter and needs the return value to directly use it. This function which called
CallCSharp will always execute before an InvokeScriptAsync call a second function. Furthermore, the content of my WebView is used in a cross platforms context so actually my
CallCSharp function more look like the code below.
function CallCSharp() {
if (isAndroid()) {
//mechanism to call C# method from js in Android
//return the result of call to C# method
} else if (isWindowsStoreApp()) {
window.external.notify(parameter);
// should return the result of call to C# method
} else {
In android, the mechanism in the webView allows to return the value of the call to a C# method, in a WPF application also. But I can't figure why for a Windows Store App we don't have this possibility.

Calling PL/SQL from JavaScript

Hi,
I was wondering whether anyone has been able to successfully call a PL/SQL function from JavaScript and have the PL/SQL function return a result to the calling JavaScript function.
What I am wanting to do is, depending on what the value returned from the PL/SQL function is, either enable or disable a button on a web form. This would be done before displaying the form. We are current using 9iAS 1.0.2.2.2a and running Portal 3.0.9.8.0
Any ideas would be appreciated.
Regards,
Scott.

Hi,
We have managed to create a solution to our problem. I have the copied in the code just incase other people are interested in what we did. We did this through Oracle Portal using the Additional PL/SQL Code section. Please see below.
is_user() is a PL/SQL function that checks whether the logged in user is a company user or client. It returns a VARCHAR2 of either "TRUE" or "FALSE".
... before displaying the form.
declare
lv_is_user varchar2(50) := is_user(portal30.wwctx_api.get_user);
begin
htp.p('<script language="JavaScript1.3">
function getItemObj(form,target)
var objname;
//Loop through all elements in the form
for(var j = 0; j < form.length; j++)
objname = form.elements[j].name.split(".");
if (objname[2] == target)
return form.elements[j];
function disableButton(form, btnName)
var isUser = "' || lv_is_user || '" ;
if (isUser == "FALSE")
var btnObj = getItemObj(form, btnName);
btnObj.disabled = true;
</script>');
END;
... after displaying the form.
htp.p('
<SCRIPT>
disableButton(document.forms[0], "FORM_BTN");

String ename = request.getParameter( "EmployeeName");
session.setAttribute( "ename", ename);
%>and then call the class from here?
looking around ive come across ajax but i dont know how to use it and what you need to install and if its compatable with tomcat and jsp?
is ajax better or not really worth it?
i have anything up to 100 fields that need saving at one save click

CALL a report from WDA using SUBMIT to sap-spool

Hi,
I need to call a report from one of the methods of a WDA application.
The out of this report is a sapscript. I want show it in WDA (PDF).
The report is called when a user clicks EXECUTE button.
The piece of the code is:
call function 'GET_PRINT_PARAMETERS'
    exporting
      immediately            = 'X'
      new_list_id            = 'X'
      no_dialog              = 'X'
      receiver               = sy-uname
      release                = 'X'
      sap_cover_page         = 'X'
    importing
      out_archive_parameters = t_arcpar
      out_parameters         = t_pripar
      valid                  = i_valid
    exceptions
      archive_info_not_found = 1
      invalid_print_params   = 2
      invalid_archive_params = 3
      others                 = 4.
      submit hbrcced0
                      with pnppernr-low eq i_pernr
                      with pnpbukrs-low eq t_p0001-bukrs
                      with pnpbegda     eq i_begda
                      with pnpendda     eq i_endda
                      with p_expot      eq ''
                      with ano          eq v_gjahr
                      with respcc       eq v_sachn
                     to sap-spool
                     spool   parameters t_pripar
                     archive parameters t_arcpar
                     without spool dynpro
                     and return.
    if sy-calld eq ''.
      message 'err' type 'E'.
    else.
If i execute this code in WDA, the sy-calld never is equal 'X'.
But if i execute it in program (SE38) the sy-calld is 'X'.
How i can call the program 'hbrcced0' in WDA ?
Cheers,
Silvio Galery

Hi Silvio,
a submit REPORT to spool does work from WDA.
ONLY when "and return" is used.
You have that, so it should work.
Note you had print immediate on, so it will be output on printer,
and not available to read after the call.
(which option was the keep after print?, I would have to check docu)
The sy-calld will be set to X inside the REPORT when it is running.
After the submit has run back inside WDA it is of course reset to space again.
Cheers
Phil.
