How to update a report  from a form on the same page when form item changes

I have a portal form from a table and a portal SQL report with a bind variable on a page. I want the report to get updated with details based upon what was selected from a form item. The form item is a selection from a dynamic LOV. Whenever the form item gets changed, the report should get updated to reflect the change. Can this be done using a javascript ONCHANGE event?
Oracle Portal Version is 10.1.2.2.0.

Your applet can open an URLConnection and read directly a document from your webserver.
public String readText() {
  java.net.HttpURLConnection conn = (java.net.HttpURLConnection)myURL.openConnection(); ...
}So using JavaScript on your page, you might call readText() to fill that textarea.
The interesting link you gave, handled the JavaScript/Applet interaction. Test that with just return "Hello";.
The real programming is more interesting.

  • How to open a link from search engine in the same page

    I just noticed that my links are opening in new windows instead of on the same page on Safari. Is there anyway I can change it back to where if I click on a link in the Yahoo search engine that it would just open within the same page without opening a new tab or window, where I can go back and forth between pages? For example, say I type in "wikipedia" on Yahoo home page and click search. Then it takes me to the Yahoo! Search Results page with a link to the Wikipedia website. When I click on that link, the Wikipedia home page loads right within the same page instead of opening a new tab or window and loading into that new tab or window. If I wanted to go back to the search results, I can just click the back button. I remember Safari doing that before, is there anyway to get back to that? Thanks.

    You can set the Integer pref <b>browser.link.open_newwindow.override.external</b> to "<i>1</i>" on the <b>about:config</b> page.
    *http://kb.mozillazine.org/about:config
    The browser.link.open_newwindow.override.external pref uses the same values as this pref for JavaScript window.open() calls.

  • How to invoke crystal reports from Oracle forms 11g R2 along with passing p

    How to invoke crystal reports from Oracle forms 11g R2 along with passing parameter to it.
    how to pass parameters to crystal report, please help.

    how to pass parameters to crystal report, please help.This would entirely depend on crystal reports and you might find informations on crystal reports related communities more likely...I for one have seen crystal reports the last time about 12 years ago. And even back then I simply acknowledged it's existence instead of working with it.
    Maybe crystal reports can be invoked via a URL call which would make it simple as you'd need simply build an URL and show the report using web.show_document. But that's pure speculation. Also you might not be the first with this requirement, so the solution to your problem might be right under your nose and just a little google search away ;)

    SQL/XML (XMLElement, XMLForest, XMLAgg, etc) and UTL_HTTP.
    Whether that works for you with the version of Oracle you have, your requirements, and needs is another story. A little detail goes a long way.

    Another method is tosave your Word document as an a web page.  Then open the htm file, copy the text and paste into an HTML snippet on your web page.  Resize to show all the document and publish. It will retain the style, font and alignment of the original Word document.

  • How to print BIP reports from Oracle Forms?

    Hi all,
    I have a question in regards to printing BIP reports from Oracle Forms... We are aiming for a server installation of BIP with integration to Oracle Forms using SSO to handle security. We use Forms built-in web.show_document to render and view the report in PDF/Excel etc... We would like to by pass the viewing and print some of these reports directly to the printer.
    Any idea/suggestions how we can go about this?
    Thanks in advance for your time.
    Yahya

    Yahya,
    via HTTP it's not possible to send a report directly to the printer. You had to go via the Scheduler, which is able to do that. With the WebService API you can call a report with the Scheduler and Execute Immediate.

  • How to get a form to appear on the same page when a button is clicked?

    Hi,
    I have a report on a page with a create button. When a user clicks the create button, a form should appear on another region in the same page....how do i go about doing this?
    I know how to do this if the form is on a different page, but i'd like the form to appear on the same page as the report and only when the button is clicked.
    Thanks.

    Hi,
    I did the following, but it didnt work....
    1) Created a hidden item on the page, and in the Default Value field, I set the value to N.
    2) Created a button in the report with the following values under "Optional URL Redirect":
    Target is a: Page in this application
    Page: 4
    Set these items: P1_SHOW_FORM
    With these values: Y
    3) Created a form of HTML text type with the following values under "Conditional Display":
    Condition Type: Request=Expression 1
    Expression 1: P1_SHOW_FORM='Y'
    What have I done wrong or have i missed something?
    Thanks.

  • How can I display the same page when I'll press

    i have a jsp page. It contains user name & password.
    and a link like SIGNOUT COMPLETELY. when i press the back button it should show only this page.
    You have noticed one thing that when u sign out from YHAOO MAIL then a page is displayed
    USERNAME : [email protected]
    PASSWORD :XXXXXXXXXX
    SIGNOUT COMPLETELY
    when this page is dispalyed and u press the back button of the browser
    it displays the same page. How it happens?

    Kindly neglect the previous post.....
    Okay check something like this
    1).maintain either a HttpSessionListener or a session flag try to checkout whether the user is active or else close the PrintWriter.
    2).Prevent caching of the webpage by using customary meta tag or by response,setHeader("Cache-Control","no-cache");
    way...
    Guess tht shud work.....

  • Opening another iview from an iview in the same page ....

    Hello ....
    I need to open another iview from an existing one in the same page without overwriting the other existing iviews on the page. I am using EPCM.doNavigate() as given below
    EPCM.doNavigate('ROLES://portal_content/com.hersheys.Hershey_Content/com.hersheys.Human_Resources/com.hersheys.hr.sap_mss_iviews/EmployeeExit?SCENARIO_PARAMS=PERNR='+person,0);
    The iview does open in the same page, however i lose the other iviews on the top and bottom of the page ....
    Any pointers??
    Thanks,
    Devina

    Hi Devina,
    Try using IUrlGeneratorService to generate the URL to the required iView, instead of EPCM.doNavigate().
    doNavigate sometimes refreshes the whole page while loading the required iView.
    cheers

  • How to keep vertically arranged fields to print on the same page?

    Hello,
    my report contains fields that are vertically arranged. I want the report to print all the fields on the same page and  not if the page is too small at the end that the half of the fields are printed on one page and the rest on the next page. But there should be more than one data sets on one page (it is no solution to generally make a page break before the fields - it only concerns the end of a page).
    Is there a printing mechanism to anchor fields together?
    Thanks in advance for your help.
    kind regards
    Monika Anna

    1. Are these vertically arranged fields within the same group?  If so, you can try right click on the Group section, Select Change Group, and then Go to Option Tab and select Change Group together.
    2. Otherwise, if you want to fit certain amount of rows into one page, then you can write your own running total and Set New Page when that running total reach eg: 20 rows.
