Calculations in Jsp form - Urgent Please

Hi,
I have 3 fields in my table, Quantity,Price and Total. Quantity * Price gives Total. Price is the Column of another table and I display the values of Price using <jbo:InputSelectLOV>. So,my requirement is when I input the value for Quantity and select the values from list in the Edit.jsp form I need the value of Quantity * Price to be displayed in the Total field on Browse form. Could someone please help me. I am new to JSP and any help is appreciated.
Thank You

It's not related to JDeveloper this is a generic thing for HTML pages - if you want to do client side (menaing no traffic to the server) actions you use Javascript.
You just need to stick the Javascript into the JSP page you have inside JDeveloper.

  • Need to update mutli record in oracle forms - Urgent please

    Hi,
    We are using Oracle apps release 11i - Oracle forms 6i.
    I have a field "project_start_date" in project_block in a custom form. There is another multi-record block called role_block in the same custom form and it has a field named start_date. Requirement is when ever I make change in the project_start_date in project_block, that should reflect in role_block.start_date. I tried different means and could update only the very first record of the multi-record block - role_block. I need to update all the records in the role_block with the same project_start_date. Used looping and several other methods. But could not achieve. Any help is really appreciated.

  • Insert / Update from Oracle Forms -- URGENT Please thanks

    Hello All,
    I need to create form which can be use for two purposes. i.e insert and update
    I have one table called emp which has 50 columns.
    Only four columns has not null constraint.
    I need to insert values in only these columns.
    From SQLPLUS it can be cone as below:
    insert ito emp values ('333','2222','007','AA','01-JAN-2007','','','','','','','','','',........);
    After that I need to update one of the coulmn with the value as
    update emp
    set zipcode = 'Y'
    where empt# = 007;
    How could I achive this from Oracle form.
    Any help will be appricated.
    D

    Why handle updates in the On-Update trigger? Oracle Forms already handles this for you. You update a data value in a field and click on the SAVE button (assuming you have a Save button) and the Oracle Forms handles the Update. The On-Update trigger is provided so you can perform processing in addition to the default UPDATE.

  • How to retrieve the parameter names from a JSP page ? Urgent Please

    Hello,
    Can anybody tell me how to retrieve the parameter names from the JSP
    page. (without using getParameterNames() method.)
    The problem with the getParameterNames() method is I get the Jumbled output.
    I need it very badly
    With regards

    Dear duffymo,
    My primary intention is to convert the JSP form information into a XML file.
    If I do not get the Parameter names in the correct order how can I maintain
    tag order in XML file.
    For ex: (JSP PAGE VIEW)
    Name--
    FirstName
    MiddleName
    LastName
    Address--
    Street1
    Street2
    City
    Country
    &so on
    (XML File to be generated)
    <Name>
    <FirstName>Value</FirstName>
    </Name>
    <Address>
    <street1>value</street1>
    </Address>
    & so on
    If I use getParameterNames() to get all the parameter names(Which form the tag names in the XML file ) the Enumeration object it returns will not be in the same order as the text fields in JSP.From this I can not construct a meaningful XML file.
    order means: Order of entry on the page, from top to bottom
    That's it
    Waiting for your responses

  • Migrating PCR frontend-JSP forms to Adobe interactive forms-WD Abap Comp

    Hi All,
    We are currently on Netweaver 7.0 & ECC 6.0 and ESS - MSS Business Package 50.4. We are using JSP Forms on portal front for Personnel Change Requests (PCR's ) where in all the scenarios in the backend are heavily customized with good amount of usage of Javascripts. For certain scenarios, where in a huge amount of information is fetched from ECC 6.0 backend system, JSP are performing really bad and the total time taken to display the form is actually causing a lot of irritation to the end user.
    We are planning to propose an upgrade to SAP adobe interactive forms. The prerequisite is that the business wants to reuse all the customized scenarios without any changes and just want to move towards better front end forms.
    My questions are:
    1. Please list benefits of SAP Adobe interactive forms - ABAP component over JSP forms (performance wise)
    2. Issues with SAP Adobe Interactive forms?
    3. Since Javascripts do not work in Webdynpro ABAP. How can we implement those front end checks and validations.
    3. Any other options available for UI that can be suggested?
    All suggestions are welcome. Quick response is appreciated.
    Thanks a lot for your time and help.
    Best Regards,
    Anupama

    Is your performance issue with the Javascript with JSP pages?  or the Java script you are using within the Adobe form in your WDJ custom application using Adobe form? I have worked on PCR's using ISR framework old school it used to call as PCR and now HCM Processes and form, Developed PCR's using WDJ also integrated workflow with the WDJ PCR for approval(we never had any performance issue) infact ISR frame work was kind of slow compare to custom WDJ solution and less flexible for a developer to develop.
    I have also worked created WDA custom application for PCR's , WDA is definitely better when you compare it with WDJ but I have not seen much performance issue with WDJ atleast on custom PCR solutions.
    I don't have any case study to share with you, can you please tell what kind of PCR's your client is using and what kind of performance issue you are experiencing and where and why you guys are using Javascript.

    Hi,
    "Cannot Create File" means forms failed to create/save the file. Check the following
    * Do you have full access to the drive?
    * Did you mark either the form or its directory as read only?

    Is your form running inside the browser window (with SeparateFrame=False)? If the browser is maximized, and your form is maximized, yet you cannot see the entire screen, you can run with SeparateFrame=True. You can do that on the browser line.
