Calling JavaScript function from Servlet ?

I have a Servlet that needs to call a general purpose JavaScript function to retrieve some data. The JavaScript function sits in a file on the web server called general.js.
How can I call this function from my servlet to retrieve an integer result ?

Calling javascript functions from xsl on mac safari

Hi,
I am having a problem calling external javascript functions from xsl on mac safari, i am trying to generate a dropdown dynamically from an xsl document using XSLTProcessor through javascript, following is the code snippet of the xsl document
<select name="ddl_EmailSubType" class="Menu" onclick="onEmailSubTypeChange();" id="ddl_EmailSubType" >
<xsl:for-each select="./SubTypeFields/FieldGroup">
<xsl:if test="@SubTypeGroup != 'All'">
<option>
<xsl:attribute name="value">
<xsl:value-of select="@SubTypeGroup"/>
</xsl:attribute>
<xsl:if test="@SubTypeGroup = $SelectedSubContentType">
<xsl:attribute name="selected">selected</xsl:attribute>
</xsl:if>
<xsl:value-of select="@SubTypeGroup"/>
</option>
</xsl:if>
</xsl:for-each>
</select>
here the function onEmailSubTypeChange() is present in an external js file, all the other functions from this files are executed successfully except the ones which are defined in the xsl document.
I have also tried replacing onclick="onEmailSubTypeChange();" with onclick="javascript:alert('hello world');" but the event is not getting fired at all since i cannot see any alert on the selected item change of the dropdown.
Is there a way in which i can achieve this ?
any helps appreciated.
Thanks in advance

ADF Question: call javascript function from backing bean?

Hi all,
I am running JDeveloper 10.1.3.3 with ADF BC.
Heres my situation:
I have a table, and after inserting a new row, then committing, I want to call a javascript function. I tried using the onkeyup javascript to force a click of the save button, and then call my function after that. However, I really only want the second function to be called AFTER the commit has occurred.
I have tried putting a setTimeout on the second function, but this never executes then. Is there some way that I can call the second javascript function from the backing bean? Is there a better workaround for this? Here is some code:
        function submitCreate(e) {
            var _event = (window.event) ? event : e;
            var KeyID = _event.keyCode;
            switch (KeyID)
                case 13:
                    document.getElementById("form1:tvoTable:commitButton").onclick();
                    doAjax();
                    break;
        function doAjax() {
            var item = document.getElementById("form1:inputText3").innerHTML;
            getAjax(item, "FULL");
        }Thanks,
Heather

Maybe try adding an af:script block in your jsp as a partial target in your backing bean when you commit to the database? We are doing something similar when we get a tab DisclosureEvent but the principle should be the same.
In our jsp we have:
<af:script id="scriptID" text="alert('javascript here');"/>
In the backing bean we have:
method(DisclosureEvent de) {
// get a component somehow or the component, we get it from the disclosure event
// but you could use a binding also. if you don't have the exact script element you need
// to find it like we do below.
UIComponent c = de.getComponent();
// Find our real script component
UIComponent target = c.findComponent(":scriptID");
// get the adf context
AdfFacesContext adfContext = AdfFacesContext.getCurrentInstance();
// add the script as a partial target.
if(target != null) {
adfContext.addPartialTarget(target);
This relies on PPR though, which you may not be doing. If you are navigating to a new page you could set an indication in a backing bean and then access that in an <af:script> block in the new page or even generate the Javascript you want depending on your logic and access all of it via an EL binding on the af:script tag:
<af:script id="scriptID" text="#{bbean.generatedScript}"/>
Hope this helps!

Call javascript functions from PL/SQL

Hi !
I just want to know if it is possible to call a javascript function from a PL/SQL procedure. If yes, anybody can explain me the syntax ?
Thanks
Chantale

You can call Java Script - kind of.
PL/SQL has a "web browser" called UTL_HTTP. It allows you to make HTTP calls to a web server. This includes a function that can be used from SQL too (with a size limitation).
Example:
SQL> select UTL_HTTP.Request( 'http://some-web-server' ) as HTML_PAGE from dual;
HTML_PAGE
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<META HTTP-EQUIV="Refresh" CONTENT="1;URL=http:/some-web-server:7777/index">
<html xmlns="http://www.w3.org/1999/xhtml">
<img src="images/Wave.gif">
Redirecting.. please standby..
<hr>
</html>
SQL>The call to the web browser can be to execute and load, for example, a JSP page.
However, if the page containts client-side Java script, i.e. code for the web browser to execute, than UTL_HTTP will merely return the contents & code of that page.
Client-side Java Script requires an engine in the browser. The JS language is used to manipulate the rendering engine of the browser.
The PL/SQL "web browser" does not have a display device to show a web page. Thus it is without a web browser rendering engine and therefore also cannot execute Java Script either.

Calling javascript function from report customization form

I have been unable to call any user-defined javascript function from Portal Report Customization forms.
Even a simple Message Box function doesn't work. I've been placing my code in the ..after header PL/SQL section for the report customization form.
htp.p('<script type="javascript">');
htp.p('function MsgBox(message){');
htp.p('alert(message);}');
htp.p('</script>');
htp.p('See if it works');
I have verified in plain html that my syntax is fine. Even the syntax rendered by portal is correct:
<script type="javascript">
function MsgBox(message){
alert(message);}
</script>
See if it works
Despite this, you will get a javascript error that an Object is expected, MsgBox not defined. Clearly from the script above MsgBox is defined.
I have tried any number of calls to user defined functions and can't get anything to work. However, calling native functions like 'alert' works fine ( ie
See if it works
Anyone know how I can call a user defined javascript function in a Portal Report Customization form?

Try changing the code
htp.p('<script type="javascript">');
to
htp.p('<script language="javascript">');
Thanks

Calling JavaScript functions from Java

Hi,
I am trying to call the javascript function alert("text message") from a section of Java code.
I want to do something like below....
if (balh blah blah...){
isFound = false;
alert("Record already exists");
Dose anyone know how to do this?

If your Java code is in a JSP page or a Servlet, then yes, but not exactly...
Since the Java portion of a JSP / Servlet is executed on the server side, there is no way to instantaneously pop up something to the user per se - the code is executed on the server before the output is transmitted to the browser.
What you could do, however, is to have a JavaScript function defined in your page which would perform the alert:
<script language="JavaScript">
function userAlert(message){
    alert(message);
</script>Then, on the jsp/servlet side, you could perform your if/else check:
String bodyTag = "<body>";
String userMessage = null;
if (balh blah blah...){
   isFound = false;
   userMessage = "Record already exists";
   bodyTage = "<body onLoad=\"userAlert('" + userMessage + "')>\"";
}This way, as soon as the browser loads the page, it alerts the user with your message.
Hope this helped,

Yes. You have to load and call them in the context of an

Are there any other function that can do that? What about parsing whole *.js file as a string?
Do you have any idea or code exaple how to do it?
Hope this is possible.
Thanks in advance for your reply.
Grzegorz

I have read it, and still don't know how to do that.
I need to put my config.js script in "app" folder-level - the plugin should be available for all users.
I have code:
ACCB1 ASBool ACCB2 PluginInit(void)
    char * jsscript = "config.js";
    AFExecuteThisScript( NULL, jsscript, NULL);
    return true;
my question is "how to run code from this file, what should variable jsscript contain?? how can I run single functions from this file?
Another question is:
is it possible to automaticaly run *.js file from "app" folder-level like it is going from "user" folder-level. I need to create plugin for all users, can't put *.js file for all users in their own folder
Thanks for the answers.
