How to implement this multi-langual APEX apps

My requirements are:
- login page has a dropdown of two languages: English (en-us) and French (fr)
- page is refreshed when dropdown value has changed.
- language is selected at login page, and this language setting cannot changed during session.
- Use cookie to store the selected language, and this language is selected once the login page is launched next time.
Implementation:
Globalization Settings
- primary lang = en-us
- Application lang derived Form = item preference
- do the translation in XLIFF files
Login Page
- create a SELECT LIST with name "FSP_LANGUAGE_PREFERENCE", list of value definition "STATIC:English;en-us,français;fr"
- After Submit
owa_util.mime_header('text/html', FALSE);
owa_cookie.send(name => 'LANG', value=> :FSP_LANGUAGE_PREFERENCE, expires => sysdate + 30);
- Before Header
l_cookie := owa_cookie.get('LANG');
l_value := l_cookie.vals(1);
:FSP_LANGUAGE_PREFERENCE := l_value;
Problems:
When the cookie is stored with value "fr", the droplist is "francais" but the page is not in French,. Also, I don't know how to set the refresh the page when dropdown value is changed.
Any suggestion ?

hello
About Refresh of the page when the value is selected:
You need to change the type of select list to select list with submit/redirect and put also a Branch in the page so the app could know where to go after submit/redirect.
About the cookie problem:
I think that the setting of the value on the page doesn't make this value is set in app.
After setting this value to any field (TEXT or LOV) you need to submit the page so the value will stick.
I remember having the same problem but didn't solved it. :/
And also I don't know if this matters but it's faster:
l_cookie := owa_cookie.get('LANG');
:FSP_LANGUAGE_PREFERENCE := l_cookie.vals(1);

  • How to implement this in Oracle Apps 11i

    Hello Friends
    I am working as a consultant for a manufacturing company.
    They have a format for charging Excise and Sales tax on their products (example below). I dont know how to implement this using oracle apps. Please help me ASAP.
    eg.
    Product A:
    MRP = Rs. 100
    Assessable Value (i.e. the value at which I have contract with the Government to pay Excise Duty) = 60% of MRP = Rs. 60 in this case.
    Excise Duty = 16% of AV =0.16*60 = Rs. 9.6
    Now, let’s suppose I am selling my product to a dealer at 30% discount.
    Therefore, Sale Price = 70% of MRP = Rs. 70
    Sales Tax = 4% of Sale Price = 0.04*70 = 2.8
    Therefore, total revenue from the deal = 70-9.6-2.8 = Rs. 57.6

    you can use Advance Pricing or creating discount or attiribute while calculating.
    this is not much complex, possible even with Advance Pricing too. Thanks

  • How to import updated version of APEX app without losing saved IR's?

    Oracle XE 11.2
    Apex 4.1
    Linux Red Hat 5.4
    ============
    Does anyone have suggestions on how to import updated version of APEX app without losing saved IR's?
    Also, I want to maintain app id from update to update (from revision to revision). In fact, I think that that is required in order to keep the saved IR's.
    The only process I have found that seems to "work" (i.e. loads new revision of app over old revision of app) is the following (via SQL*Plus):
    declare
    l_workspace_id number;
    begin
    select workspace_id into l_workspace_id
    from apex_workspaces
    where workspace = 'MYWORKSPACE';
    apex_application_install.set_application_id(400);
    apex_application_install.set_workspace_id(l_workspace_id);
    apex_application_install.generate_offset;
    apex_application_install.set_schema('MYSCHEMA' );
    apex_application_install.set_application_alias( 'MYSCHEMA_ALIAS' );
    end;
    @new_version_of_app.sql;
    but I do not have any saved reports in this app. Will this process keep the saved IR's from the previous version of the app 'intact'?
    Thanks.

    Hi,
    I cope with the same issue.
    But I've several prod instances and many applications on each of these... and SIR saved by many users.
    Of course each prod application have its own ID, distinct from the dev application ID.
    Is there really not any kind of solution in my case (apart from release the dev app on the dev workspace ; export 50 apps from it and import those 50 times, maybe more in the futur) ?
    I'd be a pity if not, I think there must be a lot of us working in that configuration.
    Thanks !

  • How to implement this attribute ?

    Hi,
    I've this problem.
    In our application to control healthcare expense I've implemented a cube with 6 dimensions. (here for who knows Italian : http://www.oracle.com/global/it/customers/profiles/profile_77.html )
    The biggest dimension is the "patient" one, with 1.500.000 units at 5th level, grouped in geographic aggregates, until the entire city at highest level.
    Now customers wants to have the possibility to select patiens with chronic disease from these. There are about 500 kinds of chronic diseases.
    Every patient can have no one, one, or (and this is the problem) more then one of these chronic disease.
    How to try to implement this? as a new dimensions or as an attribute ?
    I've thought that best way is to introduce a new (chronic diseases) dimension, to have a way to select one or more of these diseases at all levels of patient dimension.
    I'm asking how to solve the problem that a single patien can also have more than one disease.
    Is there any way to implement this ?

    thanks to everyone for the answers
    I've some questions.
    to olapworld:
    have you any sample code to show me how to implement the dimensionalized valueset and the customizations needed ??
    to scott:
    I think I'm not understanding your suggestion:
    my target is to add the "ilnesses" selection to other ones. The most important cube of my applications analyze
    healthcare expenses from six dimensions. Customer wants analyze cube "adding" a way to select only "ilnesses" patients and elvaluate their expense.
    I'm in doubt becouse a patient can also have more then one ilness, so I can't simply add a "ilnesses" dimensions to the cube and mapping it to an "ilness_id" in the fact table.
    How can the two dimensioned cube to help me in this ?
    to Rafalm1:
    in any case, implementing Count(Distinct patient) would be useful for me, to have a way to count the number of patients who had a healthcae assistence. Can you suggest me how to implement this ?

  • How to implement this Form page in ApEx

    Hi,
    I'm using ApEx 4.0.1 with Oracle 10g r2.
    We have an old form (built with Forms 10g) that we want to implement with ApEx.
    Data are shown using some items and I can't find how to do the same with ApEx. It is quite hard to explain so here is a screenshot (png) : http://bailly.yann.free.fr/autres/OTNForums/form_mesures_offsets.png
    Buttons with arrows allow user to navigate through the records. A PL/SQL program is currently used to fetch rows.
    So it seems I can't use a report because I can't fetch all rows with a single query.
    And I don't want to use modifiable items (textfields, textarea, ...) like in that form but simply show all data.
    Any idea on how I can achieve this ?
    Thanks!
    Yann.

    So it looked to me like a single form tied to a custom query to retrieve the data will be sufficient. I would start with about 5 items including your key id. Then create a custom procedure that fires BEFORE HEADER like this:
    declare
    begin
      select COL1, COL2, COL3, COL4
        into :PX_VAR1, :PX_VAR2, :PX_VAR3, :PX_VAR4
        from MY_TABLE
       where KEY_ID = :PX_KEY;
    end;You can make the SQL retrieval as complicated as you need. You will have to determine how to populate the Key field, whether that is by passing in a variable from another page or using another process to get it. Once you have a few items working, start creating the rest of your page items and add them to the query procedure.
    If you need to change any of them, you can create a second procedure that saves the information back to the DB:
    declare
    begin
      UPDATE MY_TABLE set COL1 = :PX_VAR1, COL2 = :PX_VAR2, COL3 = :PX_VAR3, COL4 = :PX_VAR4
       where KEY_ID = :PX_KEY;
    end;

  • How to implement this function in JSP/Servlet env?

    Hi all,
    I working on a project, it provides functionality to upload file using JSP/Servlet. In the first JSP page, there is file location and submit button. After user select a file to upload and click submit button, a message, like "sending file to XXXX", will be shown on the screen. Once uploading and validation are done on the server-side, a successful/error msg will be shown to user.
    Here I have a question for the "sending..." msg and the successful/error msg. They should be put in one jsp page or in two separate page? how to implement them?
    Thanks for any help!
    Tranquil

    For the sending message... Well, the thing is, when you click submit, it's sending the file to the server and the server is processing it, and this is all done before the "complete" page is sent to the server. So one would need to use some Javascript on the page before the actual submit happens to show some message. This is done on Ebay when you put something for sale, you can upload an image, and there is a little popup message telling you that it's uploading, and it is removed when the process is done. Now, I'm not sure the exact details of how this works, but my educated guess is this:
    1) The onsubmit function of the form checks that the file upload fields have a value (no need to popup a message if no file upload, since that's what usually takes the time, although it could just be assumed there is a file). If a file is to be uploaded, or just want to show the message anyway, a new popup window is opened with the window.open method and the "sending" message is shown (either written via Javascript or just load a small web page to the window).
    2) The popup window, since you can't transfer the window object from the form page to the next page, has to check window.opener for some value that the success/error page would have to set. The success/error page could use it's body onload function to set a variable in it's own window object to denote that the page is loaded. The popup window can use a looping check using setTimeout or setInterval in Javascript to check for window.opener.isLoadedVariable to be present, and if so, close itself.
    I've never done that, but I see no reason why it wouldn't work.

  • How to implement this typical sign workflow? Urgent

    Hi Adobe Experts,
    I am new to LC (two months only). Recently company is doing some evaluation on LC 8.2 and my boss assigned the following task to me  (I simplified it):
    Form: (Enclosed)
    * Two text fields: CommentTextField1 and CommentTextField2
    * Two signature fields: SignatureField1 and SignatureField2
    I've associated the SignatureField1 to lock CommentTextField1 and associated the SignatureField2 to lock CommentTextField2.
    The progress to implement is:
    Step 1) Ray Woodard open the form in workspace, type in CommentTextField1, Sign the SignatureField1, Submit.
    Step 2) Alex Pink open the form in workspace, type in CommentTextField2, Sign the SignatureField2, Submit.
    Any suggestions on how to implement the progress? Please help! Thanks a lot!
    (What I am able to accomplish so far is the step 1, but I am not confident about that. Please point me the right solution. Should I use xfaForm or Document Form, render/submit as default or PDF, submit as XDP or PDF etc...? I am so confused and frustrated now!)

    Steve, thank you so much!!!
    Your example helped me a lot. I am able to run the process, but I still have three doubts:
    1) When I set "Submit As" to "PDF" rather than "XDP" by default, I am not able to submit the form in the workspace client with "Adobe Reader" installed. But I am able to submit the form in the workspace client with "Adobe Acrobat" installed. Is it normal?
    2) What does "Form Bridge" do in this whole process here?
    3) If I don't want to hard code the submit URL  in the form, do I have another option, like using other renders?
    Thanks again!

  • How to implement this need help

    I created a datacontrol for a named query which (using Ejb entity beans) which accepted a employee id and click on find show me the respected employee details in a table.
    case 1: In one single page
    when i added the form consisting of a single text box , button and the table to show the result of the find method in one single page it worked out perfectly,,,
    case 2 : using 2 different pages
    But then i tried adding only the form in one page named page1 and and the table to show the result in another page i.e page2 , Also in the command action of find button of page1 i asked it to redirect to page 2 and show result . But it never showed me any results..
    Question :
    1) How to implement case2 i.e to have a form on one page and the resultant table to be show on another page i.e When users sees first page he adds the employee id in text box and clicks find .The user then needs to be redirected to page2 and the result of search should be shown in table...
    Can anyone guide me over this... ???

    Hi,
    you use a method on the EJB that takes a argument (e.g. the employee ID). You then put the method result set on page 2 (the method argument shall be pointed to a request or session attribute using EL : #{sessionScope.EmployeeId}
    On the search page - when the user hits the search button - you set the attribute "EmployeeId" in the session before navigating to the next page

  • How to implement this? please help

    In my java class, I have a string array called strarray which hold serveral elements, some of the elements have the same value , for example, the first element is "swimming", the forth element is also swimming. I use a for loop to get each element and give it to arrayHolder which is also a array with the same size as strarray. Now, what I want is: I defined a Vector called element I want this vector to filter out the element from arrayHolder, get the name of non-duplicated name from the arrayHolder, the result should be inside the element vector (swimming,walking,running,dancing), no duplicated name. My code is like follows:
    import java.util.*;
    import java.io.*;

    Vector element=new Vector();
    for(int i=0;i<strarray.length();i++){
    arrayHolder[  i  ]=strarray[  i  ];
    /* What should I do next to get the non-duplicated element from arrayHolder and

    Not sure if I see the use of strArray & arrayHolder (I've not looked at your code - you might use code tags next time (check the "code" button above the message textarea), but may I suggest using a Map of some sort instead of a Vector? It will prevent duplicates for you.
    Good Luck
