If you are trying to display total number of pages in a report, Add the below formula in the column of the report and hide that column in the report.
FX = sum(count(1))/25
You can then reference the column in the narrative view like this: "Total pages in the report are @5" and out put may be "Total Pages in the report are 30".
Or
You can also use something like the below:
To calculate them use fi:
CEILING(CAST(RCOUNT("FactColumn In the Report (Sum All)") as DOUBLE)/ 25) for the page number
CEILING(CAST(COUNT("FactColumn In the Report (Sum All)") as DOUBLE)/ 25) for the total pages
Put the above formula in the column and reference it in the narrative view like I mentioned in the previous example.
If you are report view is pivot, then please refer to this link: http://oraclebizint.wordpress.com/2008/01/17/oracle-bi-101332-pagination-in-pivot-tables/
Hope this helps.

  • How to use JavaScript in Web bean generated JSP

    I want to do some simple JavaScript validations (for example, checking if a particular field is empty) in the JSP page rendered by the data web bean. Because the HTML is rendered by the bean, I'm not able to refer to the HTML controls in the JSP page. I'm not even able to refer to the form with the following standard piece of JavaScript code - "document.forms[0].control_name".
    Is anybody aware of how to use JavaScript with these rendered JSP pages?

    You just have to add it like and applet , including this line in your JSP or JSF
    <script src="http://dl.javafx.com/dtfx.js"></script>Then add the applet
    <script>
        javafx(
                  archive: "./resources/jar/Draw.jar",
                  width: 400,
                  height: 200,
                  code: "Draw",
                  name: "Draw"
    </script>./resources/jar/Draw.jar - is the path and the name of the jar

  • How to Use JavaScript in Controller Class...

    Hi All,
    Can any one tell me how to use JavaScript in Controller Class.
    Requirement is:
    I have
    Radio Group(RG1),
    Two Radio Buttons(RB1,RB2),
    Two messageTextInput(MTI1,MTI2),
    if i click RB1 i should Prompt to the end user to "Enter value for MTI1" or
    If i click RB2 i should prompt "Enter value for MTI2" while submitting page.
    Please let me know the steps to use JavaScript and the above client validation...
    Regards
    Alem...

    Using javascript is against the standard. I can tell you a workaround instead of you setting the javascript, check if that would be acceptable.
    You can use PPR and set the required property on the messageTextInput on clicking of the radio button. By doing this you will let UIX generate the javascript for you to handle the client side validation. But the validation will happen only on click of the submit button. The visual indicator is good enough to tell that the value has to be entered to the item.

  • Help me!! How to use JavaScript with JSP ??

    I am using JDeveloper and I created a screen in JSP which uses a bean for database connectivity and retriving info onto the page.
    The page has a ListBox where list items are populated from the database.My requirement is
    whenever the list is changed the page shuold be refreshed with the selected item info.
    I tried to use 'JavaScript' for triggering the event with 'onChange' event of the ListBox.But the event is not getting invoked. I think JavaScript is not working with JSP.
    Please help me with how to Use javaScript with JSP or any other alternative where I can meet my requirement.

    We have a similar need. We have used Cold Fusion to display data from Our Oracle Database. We have a simple SElect Box in HTML populated with the oracle data. When someone selects say the State of Pennsylvania. then we have an On change event that runs a Javascript to go get all the cities in Pennsylvania.
    Proble we are having is that inorder for the Javascript to work , we currently have to send all the valid data.
    Do you know of any way to dynamically query the the Oracle database in Javascript

  • How to use Javascript to load random pages?

    I wonder if anyone knows how to use Javascript to load a list

    Every address will take a line, and the Javascript will
    randomly select one of the addresses to load.
    The user will click the button "random" and access the page
    randomly selected by the script.

    Addition note:
    I forgot to say this because my computer froze......(how

    I got the code for random accessing the links.
    But now the problem is, is there anyway to parse a text file

  • How to use JavaScript in Dynamic commandLink

    Hi All,
    In my JSF application, I am able to get the dynamic CommandLink with the below mentioned code.
    commandLink.setActionExpression(createActionExpression("#{myBean.myMethod}", String.class));
    The above code is navigating to the page mypage.jsp properly (the page which is returned by method myMethod).
    My Question is: Instead of navigation (as mentioned above) I want to generate a popup window using JavaScript on click of commandLink.
    Please suggest me on how to proceed on this?

    Hers is my JavaScript:
    function showPopupWindow(action) {
    formId=action.form.id;
    //features="height=300,width=250,status=yes,toolbar=no,menubar=no,location=no,scrollbars=yes";
    features="toolbar=no,location=no,directories=no,status=no,menubar=no,scrollbars=yes,resizable=no,width=900,height=500,top=80,left=80";
    winId=window.open('Mypage.faces','list',features); // open search window
    winId.focus();
    This works perfectly with the onclick attribute of the commandbutton as shown below:
    <h:commandButton value="Open Popup" onclick="showPopupWindow(this); return false;"></h:commandButton>
    {color:#ff0000}
    But I tried same thing with the onclick attribute of the commandLink, that did not work.
    <h:commandLink value="Open Popup" onclick="showPopupWindow(this); return false;"></h:commandLink>
    {color:#0000ff}As per my requirement, I tried using setOnclick attribute in the following manner, that failed to open the popup:
    commandLink.setOnclick("{color}{color}*{color:#0000ff}showPopupWindow(this); return false;{color}*{color:#ff0000}*{color:#0000ff}");{color}*
    {color}

  • How to use JavaScript to Open a link automatically

    Is there a method (using JavaScript) to allow a user clicked link to open the link through a “intermediary” page?
    For example, say I have a web page with a embedded Flash file that contains links to several different (outside) web pages. The behavior I want is that the user clicks a link (within the Flash file), a HTML window opens (over the 1st HTML/Flash window) with the new content, leaving the original Flash/HTML window displayed in the background. The user reads the new content. The user can then close the newer window and be back at the displayed HTML/Flash file.
    The twist is that the link embedded in the referring Flash/HTML file goes to a “intermediary page”. Call that the “collector” page. I control that page. On that page I have collected (in a list) all the actual outside URLs (I do this so that I can easily change the URLs using HTML rather than having to edit the Flash file.) The Flash file contains essentially the same URL for each outside location (plus a variable unique to a specific URL).
    The user should not ever actually see this intermediary/collector page. Instead, they click the link, a variable is passed from the referring page to the collector page and fires the corresponding link automatically (replacing the content in the newly created window). Since the link fires automatically the content in the new window (initially created by the collector page) changes to the destination content.
    Is this possible?
    What JavaScript functions are used?
    How are the referring links constructed in the Flash so the variable is passed to the collector page?
    How does the “collector” page auto open the actual content?
    If anyone can point me to descriptions on how this might be done I’d certainly appreciate it.

    >is there a way i can call javascript without security checking?
    It wouldn't be security if you could just bypass it. Did you read all
    the security notes? You might be able to do something with trusted
    functions, but I'm not sure how that would integrate with a plug-in.

  • How to use Webservice in Visual composer

    Hi,
    We have developed a RFC in R3 and converted it into Webservice. We want to use this in the Visual composer. Can anyone suggest some steps how to use this RFC in Visual composer?
    I tried the option in Tools--> Define webservice System and gave the following parameters:
    new system name = WDP (system name which we use)
    new system alias = WDP_VC (system alias which we created)
    webservice url = URL of the webservice which we have created and got in WSDL
    when we create it gives an error the URL is incorrect.
    Kindly let me know if these values are correct and suggest the steps to be followed. Also, if there are any prerequiste steps to be done before using this webservice.
    Thanks and Kind regards,
    Rajbarath.

    Hi,
    The option you described refers to defining a new web service system in the portal system landscape. So if you already have it defined - you don't have to define it again.
    As for the actual error you're getting, check that:
    1. The url is indeed accessible, and points to a wsdl. You can do this by simply inserting it in the browser's address bar and making sure you get a wsdl file in the response.
    2. Make sure that you don't need to authenticate, i.e. provide a user and password. Maybe you just forgot to provide these arguments.
    Lastly, keep in mind that this 'Define Web Service System' option is just a shortcut. Generally, you would define a web service system in the portal, like any other system, using the web service connector.
    Hope this helps,

  • Problem using javascript to submit jsf form, values not submitted

    Greetings!
    I have a t:selectOneMenu where I want the page to be submitted when they change the selected value. At this point, I am able to get the form to submit and reload the page, which is all fine. The problem is that none of the values from the page are not set in the backing bean. I have break points on the setter methods that are not being hit.
    I have tried a number of things from searching multiple forums, but here are snippets from my latest version...
    <h:form>
    <t:commandLink id="hiddenLink" forceId="true" value="test link"
    action="#{pc_PageX.doBtnHiddenLinkAction}"></t:commandLink>
    <t:selectOneMenu id="pageList_top" forceId="true" value="#{pc_PageX.ValueX}"
         onchange="jspellSync(); submitPageX();">
         <f:selectItems value="#{pc_PageX.ListX}" />
    </t:selectOneMenu>
    </h:form>
    function submitPageX(){
         var hiddenLink = document.getElementById("hiddenLink");
         hiddenLink.click();
    }Note that the <t:commandLink> is not hidden, though it will be in the final version if I can get this to work.
    If I click the commandLink myself, the page is submitted with all the page values as expected. If I change the list value, thus using javascript to fire the commandLink's click event, the page is submitted with NO values.
    Can anyone come up with an explanation for this behavior? Or better yet, a solution?
    A couple other things I've tried...
    - Not using a commandLink and using jsf's submit function -> onchange="jspellSync(); submit();"
    - Clicking the link using other ways -> hiddenLink.fireEvent('onclick');
    If all else fails, I'll just add a button that they have to click to submit the form.

    I recall this problem in one of the ancient JSF versions. Which JSF version do you use? Do you have any room to upgrade to latest? We're using an IBM implementation of JSF, which is at version 7.0. The IBM implementation appears to be built on the JSF base 1.1.That's not an IBM JSF implementation, they do not have any one, they just have some component libraries which runs on top of some JSF implementation. RAD/WSAD ships by default with Sun JSF RI. Try upgrading to at least 1.1_02 which you can download from the aforementioned link. There's a gap of 2 years (and inherently a lot of bugfixes) compared to 1.1. If the application server used supports Servlet 2.5, you could even upgrade to the latest 1.2.
    We've had other issues with the IBM implementation, which could be the cause in this case too. We've been talking about switching to MyFaces, but there is one feature of the IBM version that we like. It's basically a script collector (hx:scriptCollector) that allows us to do pre-processing on the page.As said before, IBM does not have a JSF implementation. So replacing RI by MyFaces wouldn't make any difference.

  • How to use Javascript, C#, or Java to automatically fill out a PDF file using ACROBAT PRO

    Hi.
    I have purchased a copy of acrobat pro and am currently using it to try to create a method of populating certain fields in a PDF file.
    This particualar scenerio is a printable cerficiate, it has a spot for the persons First Name, Last Name, and other basic info.
    So we have an exisiting editable PDF, a database with the user's info, and a ASP.NET web server, and of course Acrobat Pro.
    How can I use these components to create an auto fill script?
    Ideally, we'd genereate these certs on the fly, and allow users to download them.
    A code sample would be awesome.

    I've discovered that you can create a "PDF Form" and edit that form with Javascript.
    My question now is, what is the prefered method for controlling the pdf form?
    I would like to include the PDF file in an HTML page and edit the form fields using javascript in that HTML page.
    I think that this is how developers are meant to work with dynamic pdf files.
    In the acrobat javascript reference, it only shows an example using the acrobat javascript console.
    If anyone has used Javascript with PDFs, I would highly appricate some input.
