Accessing html field value from pl/sql code, in the same package

hi friends,
my pl/sql web application is working fine. but now i need a small requirment.
ie, basicaly i need to access the user entered value of an element in html based form from pl/sql code, which is developed using pl/sql toolkit.
Here is the scenario:-
User entered a value in field1, then navigate to field2, and click a button for list of values,
when he clicks the button, internaly it is opening a cursor, where i want to pass field1's value to my cursor as a parameter. So in my pls/sql code , i want to access the value of field1. If you know, please help.
see the snippet of code.
htp.p('
function f1()
if (parseInt(learnIdx) ==1 )
for i in dev_Need('1')/*here i want to pass html form element value as a parameter */
loop
htp.p('content += "<option value='''||a.version_name||'''>'||a.version_name
||'</option>''"; ');
end loop;
thanks in advance.

Hi,
Here's my suggestion
If you wanna access the dll check out "external procedures", you can search it everywhere in OTN.
However it's easier to use Heterogenous Services to connect database with other sources.

Accessing a private variable from a public method of the same class

can anyone please tell me how to access a private variable, declared in a private method from a public method of the same class?
here is the code, i'm trying to get the variable int[][][] grids.
public static int[][] generateS(boolean[][] constraints)
private static int[][][] sudokuGrids()
    int[][][] grids; // array of arrays!
    grids = new int[][][]
    {

Are you sure that you want to have everything static here? You're possibly throwing away all the object-oriented goodness that java has to offer.
Anyway, it seems to me that you can't get to that variable because it is buried within a method -- think scoping rules. I think that if you want to get at that variable your program design may be under the weather and may benefit from a significant refactoring in an OOP-manner.
If you need more specific help, then ask away, but give us more information please about what you are trying to accomplish here and how you want to do this. Good luck.

Displaying a field value from PL/SQL

I'm working on a master detail form. In the detail section, I have added a button beside one of the fields. On the click of this button, I want to use a foreign key value from the current record, and get the description field from another table. I'm able to get the value from the form by use of p_sesion.get_value_as_NUMBER. I then perform the select statement to retrieve the description from another table. I would like to display this value to the user. Any ideas as to how I can do this?

Bala,
Just an update to let you know what we've tried up to this point:
We have created 3 functions:
1) Set_Occup_Desc - this sets the Occupation Description.
2) Get_Occup_Desc - this retrieves the Occupation Description.
3) Clr_Occup_Desc - this clears the Occupation Description.
On the click of the button, I have the following code:
declare
my_occup_desc varchar2(525);
my_occup_key number;
my_return_val boolean;
begin
my_occup_key := p_session.get_value_as_NUMBER(p_block_name => 'DETAIL_BLOCK', p_attribute_name => 'A_OCCUP_KEY', p_index => 1);
select occup_desc into my_occup_desc from wsoccup where occup_key = my_occup_key;
my_return_val := wsurv_util.set_occup_desc(my_occup_desc);
end;
In the After Displaying Form section, I have the following code:
htp.p(wsurv_util.get_occup_desc());
This doesn't display anything on the page, and I think that it's because multiple oracle sessions are being used within the one portal session, and the value of the variable is being lost.
Any ideas on a work around for this one?

How to get the value from a JavaScript and send the same to Java file?

How to get the value from a JavaScript (this JS is called when an action invoked) and send the value from the JS to a Java file?
Thanks and regards,

Yes, I am trying with web application.
In the below code, a variable 'message' carries the needed info. I would like to send this 'message' variable with the 'request'.
How to send this 'message' with and to the 'request'?
Thanks for the help :-)
The actual JS code is:
function productdeselection()
var i=0;
var j=0;
var deselectedproduct = new Array(5);
var message = "Are you sure to delete Product ";
mvi=document.forms[0].MVI;

Remote devive access and acquiring signals from a different PC in the same LAN

Well, I'm still interested in knowing if the way to see the DAQ channels from one PC to another located in the same LAN is the Remote device acess RDA?
If the answer is yes I would appreciate the information from sombody who has done it.
Thanks

Please don't create another question. I answered you to a previous one that is the same than this. Here is also the response.
Hello,
the only easy way in order to do that is to use RDA ( Remote Device Access ). This is a component that is installed when you install NI-DAQ. Currently, RDA is only supported by Traditional NI-DAQ. So, if you have programmed your application using NI-DAQmx, it might be more dificult because you will have to use networking communication VIs as Datasocket,TCP/IP, ....
Here you have a link about RDA. There, there is a link to an Application Note called Networking Two PCs for Remote Data Acquisition

Accessing Excel cell value from PL/SQL

I Would like to part my question into 2 sections. Both are related to PL/SQL
(Version 8.x or 9.x) COM automation
A). I have a spreadsheet with some values in the following cell address
File Name : Employee.xls
Worksheet Name : Emp_Detail (There are other spreadsheets)
Cell Address
Employee id : C50
Name : Z10
Address : X10
I will have to grab the follwing cell values and insert into the staging table
usinf PL/SQL. I have read some of your article realting to OWS package which
retieves the whole excel spread sheet.
B). I have a Activex control developed in VB6.0 and registered. Inside the dll there is a class
AccessXLS.cls, which uses the objects/functions relating
to the Excel spreadsheet.
I would like to know is there any COM automation method
to activate the dll from my PL/SQL.

(oracle 10.2) Access to v$session from pl/sql code

Hello,
I wonder if anybody can help me with the following problem as I have read some previous posts on similar topics but could not come to a solution so far.
The problem is simple: I need to select some columns form v$session from within a PL/SQL body in oracle 10.2.
Now, the "Application Developer's Guide - Fundamentals" reads:
"The owner of the procedure or package must be explicitly granted
the necessary object privileges for all objects referenced within the
body of the code."
However, if I connect sys as sysdba and run "grant select on v$session to <proc owner>" I will get "ORA-02030: can only select from fixed tables/views".
Any hint about this?
Thank you in advance.

There is nothing wrong with your instance, v$session is a public synonym for the "real" view v_$session. You cannot grant on a synonym, only on the underlying real object.

Hi,
If you look at the Java Doc for the entrySet method here http://download.oracle.com/docs/cd/E15357_01/coh.360/e15725/com/tangosol/util/QueryMap.html#entrySet_com_tangosol_util_Filter_ you will see that it returns a Set of Map.Entry instances so you need to do this...
Set setResults = cache.entrySet(createFilter("homeAddress.state = 'MA'"));
for (Iterator iter = setResults.iterator(); iter.hasNext(); )
    Map.Entry entry = iter.next();
    Contact c=(Contact)entry.getValue();
    System.out.println ("firstame####=" + c.getFirstName());

How to pass field value from popup window to oninput processing of other pg

Hi,
I want to pass a field value from the popup window to oninput processing of main page ( from where popup window is triggered). and need to close the popup window. How to do it ?
In the popup window's oninputprocessing, im doing some validation checks. If it passes all the validations, then only the control shd come to main page ..else it should stay in popup window only .
Regards,
Jothi.

Hi Jothi,
you can use java script to pass the value and close your popup window. use the following code.
in your popup window:
function passData(h1)
         window.opener.document.getElementById('var1').value = h1 ;
         window.close();
then call this function when you finish your validations.
in your main page layout create an input field with id as passed in the function above "var1".
In the value attribute give it your variable as follow:
<htmlb:inputField id      = "var1"
                          value   = "<%= var2 %>"
                          visible = "false" />
"var2" will be assigned the value from your popup window.
I hope this will help you..
Regards,
Husain

How to get the Output File Name as One of the Field Value From Payload

Hi All,
I want to get the Output file name as one of the Field value from payload.
Example:
Source XML
<?xml version="1.0" encoding="UTF-8" ?>
- <ns0:MT_TEST xmlns:ns0="http://sample.com">
- <Header>
<NAME>Bopanna</NAME>
</Header>
</ns0:MT_TEST>
I want to get the Output file name as " Bopanna.xml"
Please suggest me on this.
Regards
Bopanna

Hi,
There are couple of links already available for this. Just for info see the below details,
The Output file name could be used from the field value of payload. For this you need to use the UDF DynamicFile name with below code,
// Description: Function to create dynamic Filename
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File" , "FileName");
conf.put(key,a);
return "";
DynamicConfiguration conf = (DynamicConfiguration) container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File" , "FileName");
conf.put(key,a);
return "";
With this udf map it with the MessageType as
(File Name field from Payload) > DynamicFileConfiguration>MTReceiver
Thanks

Retreiving a value from and SQL query

If anyone can give me sample code or pointers to retreive a value from an sql query, I'd be greatful.
Source code I've muddled together so far:
Class seqNumType = Class.forName(nameOfClass);
Constructor theConstructor = seqNumType.getConstructor(null);
Object seqNumInstance = theConstructor.newInstance(null);
String theStatement = "SELECT value INTO v_seqnum FROM DUAL;";
OracleCallableStatement ocs = (OracleCallableStatement)conn.prepareCall(theStatement);
ocs.registerOutParameter( 1, OracleTypes.NUMBER, 0);
Method method = seqNumInstance.getClass().getMethod("getORADataFactory", null);
seqNumInstance = ocs.getORAData(1, (ORADataFactory)method.invoke(null,null));
ocs.execute();
Problem with this seems to be the ORADataFactory isn't a method of the class, but as I'm thumbling around in the dark here a little, I've no idea where to go from here. Is this just generally overkill anyway?
Suggestions?
Cheers for any help.

Like this:
            ResultSet resultSet=statement.executeQuery("SELECT * FROM TEST");
            while(resultSet.next())
                for(int i=0;i<resultSet.getMetaData().getColumnCount();i++)
                    System.out.print(resultSet.getObject(i+1).toString()+" ");
                System.out.println();
