How to pass value from Javascript function to a Java class method

Hi All,
I want to pass a value, which I catch in a Javascript function to a method in a Java class. I have tried many combinations but it gives me error.
This is the way I am doing
function assignBill() {
proj = projPh.substring(0,indSlash);
<% myproject.getProj(" project_cd = '" + proj + "'");%>
proj is the variable which I want to pass to getProj methods.
If any one has done this, please let me know. Thanks for your help.

The only way to receive something from clients page is to submit it somehow: through a form or link, but the info has to make it back to the server obviously. I dont know how your app works, but you can use the the javascript -location.href- function(i think) to submit the var to the server and process it there.

How to pass values from one function to another

I think you need to spend some time reducing your code to practical levels. You seem to be passing everything in the book to every function and I would guess that probably none of it is necessary. If you declared those variables at the beginning, then you don't need to pass them into any function because they are gobally available to any of the code/functions that follows them. Similarly, if you have textfields on the stage, you do not need to pass those into any functions for the same reason.
I see you making overuse of "delete" (and possibly errant use as well). Probably the only thing you might want/need to use is...
delete Subjectxtimer_mc.onEnterFrame;
Which stops the enterframe activity from firing off, which I will guess is being used to update the textfields that indicate the time.
And that conditional that uses == Nan isn't likely to do anything except wonder what an Nan is. Textfields hold strings, which are quoted. SO unless you have a variable named Nan somewhere that has a String value assigned to it, that conditional won't be doing anything for you. You probably won't need it at all if you get this working properly.

How to return Values from Oracle Object Type to Java Class Object

Hello,
i have created an Oracle Object Types in the Database. Then i created Java classes with "jpub" of these types. Here is an example of the type.
CREATE OR REPLACE TYPE person_type AS OBJECT
ID NUMBER,
vorname VARCHAR2(30),
nachname VARCHAR2(30),
geburtstag DATE,
CONSTRUCTOR FUNCTION person_type RETURN SELF AS RESULT,
CONSTRUCTOR FUNCTION person_type(p_id NUMBER) RETURN SELF AS RESULT,
CONSTRUCTOR FUNCTION person_type(p_vorname VARCHAR2,
p_nachname VARCHAR2,
p_geburtstag DATE) RETURN SELF AS RESULT,
MEMBER FUNCTION object_exists(p_id NUMBER) RETURN BOOLEAN,
MEMBER PROCEDURE load_object(p_id NUMBER),
MEMBER PROCEDURE save_object,
MEMBER PROCEDURE insert_object,
MEMBER PROCEDURE update_object,
MEMBER PROCEDURE delete_object
MEMBER PROCEDURE load_object(p_id NUMBER) IS
BEGIN
SELECT p.id, p.vorname, p.nachname, p.geburtstag
INTO SELF.ID, SELF.vorname, self.nachname, SELF.geburtstag
FROM person p
WHERE p.id = p_id;
END;
My problem is, that if i use the member function "load_object" from my java app it doesnt return the selected values to the java class and i dont know why. I use the java class like this:
PersonObjectType p = new PersonObjectType();
p.load_object(4);
There is a reocrd in the database with id = 4 and the function will execute successful. But if i try to use "p.getVorname()" i always get "NULL". Can someone tell me how to do that?
Thanks a lot.

Edited by: NTbc on 13.07.2010 15:36

CallableStatement =
"DECLARE
a person_type;
BEGIN
a.load_object(4);
? := a;
END;"
And register as an out parameter.

in a servlet :
parse your xml file (see how at the end of the post) and
put the values you want in the request attributes
request.setAttribute("value1", value1);
...redirect to the jsp
in the JSP:
get the wanted attributes:
String value1=(String)request.getAttribute("value1");To learn how to parse a xml file, pay a look at this page, it explains how to read the XML document to build an object representation, and then how to navigate through this object to get the data

If you choose the second alternative you should erase these global variables after the second form is opened
You can erase the global variable using:
erase('global_var')

How to pass value from JSP to Javascript?

I want to pass 2 integers to Javascript to do checking? How can I do that?

Well, it is very simple, Follow these steps.
1. Have a form with fields
2. On submit validate the form using javascript
3. If the javascript returns false do not submit the form
4. if the javascript returns true submit the form
5. The destination jsp page will handle the db operations.
1. <form name="frm1" action="dbcheck.jsp">
<input type="text" name="txt1">
<input type="button" value="submit" onClick="return validate();">
</form>
put the above piece of code in the <body> tag
2. Upon submit the js function validate() will be called :
<script language="javascript">
function validate() {
if(document.frm1.txt1.value="") {
alert("enter text");
return false;
else {
document.frm1.submit(); // i am not sure whether the () after submit is required or not
put the above piece of code in the <head> tag.
3. Now when the submit happens, the control goes to the dbcheck.jsp
this is dbcheck.jsp:
<%
String str = (String) request.getParameter("txt1");
------other db operations go here --------
%>
"txt1" is the field name of the textbox from the form u previously submitted.
all da best

How to pass values from main window to pop-up window?

I want to pass a value from the main window (1st form) to pop-up window (2nd form). The first form is of name booking.jsp and 2nd form is of name Fund_booking.jsp. I am using window.showModalDialog to open the window. I think, I have written right code in main window to pass the value but even then I am not able to get it on pop-up window. I am not even able to display an alert on pop-up window saying "hi" by writing a function on save Button in pop-up window. The code is as follows:
On booking.jsp:
<script>
function popup()
var aForm;
aForm = D_requisition_id.options[D_requisition_id.selectedIndex].text;
\\Here I have captured value from a drop down box in my main window form and assigned it to the variable.
alert(aForm);
var myObject =new Object();
myObject.Brandcode = aForm;
alert(myObject.Brandcode);
window.showModalDialog("Fund_booking.jsp",myObject,"dialogHeight:400px;dialogWidth:420px;");
</script>
<button name="B_FundBooking" tabIndex=4 style='POSITION:absolute;LEFT:393;TOP:292;WIDTH:100;height:24;BACKGROUND-COLOR:buttonface' onClick ="popup()">Fund Booking</button>
On Fund_booking.jsp:
<SCRIPT>
var oMyObject = window.dialogArguments;
var sBrandcode = oMyObject.Brandcode;
alert(sBrandcode);
</SCRIPT>
Even the following alert is not getting displayed in pop-up window;
<script>
function ValidateData()
alert("Hi");
</script>
<button name="B_Save" tabIndex=1 style='POSITION:absolute;LEFT:255;TOP:315;WIDTH:75;height:24;BACKGROUND-COLOR:buttonface' onClick ="ValidateData()">Save</button>
I am using DIV instead of frames in my both forms. I just want to get that value in my pop-up window to write a query based on which data will get displayed in my table of pop-up window.
Plz help me to solve this problem.

Well, this is actually a JavaScript question, not a Java question but I can give some hints.
When you do pop-up windows you need to put JavaScript in the html of the pop-up itself. Data can be passed by creating new fields in the window object, which the popup can access via the window.openner field.
So, before invoking the popup add any data to be passed to the window object, then the onLoad function in the popup grabs the data.

How to pass value from report to form?

Dear,
I built a report and I create button on report too. This
button will show a form that I want it to automatically show
receivable values from report so that user don't complete them.
So I create a button on the report . I enter Javascript in
PL/SQL Code tab in '...after displaying the footer' as follow :
htp.formOpen
(owa_util.get_owa_service_path||'portal30.wwa_app_module.link?
p_arg_names=_moduleid&p_arg_values=1736929105&p_arg_names=_show_h
eader&p_arg_values=YES&p_arg_names=GNO&p_arg_values=1&p_arg_names
=QNO&p_arg_values=2');
htp.formSubmit(null,'New Answer');
htp.formClose;
GNO , QNO is value which I want to pass
As you can see, the above code can pass only static value.
But I want to pass values that is the condition of this report.

Hi Marc,
Yes, you have it correct in what I am trying to do and if I put a default value in the hidden item on page 2 and run it then that works fine. I just can't get the value from the form passed to page 2 for some reason. There are actually 22 items on the form that can be filtered but just using COREID for simplicity. When I run the form I am just entering a value in the COREID field to try and return those records. Most of the other items on the form are displayed as Popup LOV(fetches first row). Would the values of all these be done the same in a comma delimited list for the items and values? I was trying to get at least one of them working first. Here is the search result that comes up in the debug window:
Search Results
0.01: Item: P2_COREID HIDDEN
0.01: show report
0.02: determine column headings
0.02: parse query as: MOTEAMSAPEX
0.02: binding: ":P2_COREID"="P2_COREID" value=""
0.02: print column headings
0.02: rows loop: 15 row(s)
No data found.
Here is the SQL statement:
select coreid, serialnumber
from MOTEAMS.V_ASSETS where
instr(UPPER("COREID"), UPPER(:P2_COREID)) > 0
The branch settings are:
Set these items: P2_COREID
With these values: &P1_COREID (also tried this with period at the end)
I am new to this and not familiar with apex.oracle.com. How would I go about posting to that site?
Thanks,
Pam
