Java newbie - loadField onto an HTML page

Hi, I have very limited Java knowledge and this is probably a dumb question but I am hoping for some help. I am using "loadField" to pre-load a value on an HTML form but I also want the user to change that value if they think it is incorrect (in this particular case it is a telephone number). I do not have the field set as "readonly" but when the form displays the user is not able to change the value. What am I missing to get this to work?

I guess I may have answered my own question - I see that you can highlight the field and then hit "delete" to remove the default value and type in a new value. I guess I still have a question: Is this the only way it can be done or can you leave the value in the field and then type over it?

  • Recordset onto basic HTML page

    How easy is it to insert a recordset onto a basic html page.
    Obviously I could convert the page to ASP and be able to do it, but
    this particular page has links to it all over the shop and changing
    the extension is not really possible.
    Thanks

    Impossible if you really mean "basic html". HTML has no
    facility for
    working with server-side data.
    Now - you could ask your host to parse all html pages as if
    they were ASP,
    but then you'd have to write the code yourself, because DW
    won't know that
    foo.html is actually capable of supporting ASP/VBScript.

  • How do I hide the grey java applet box in a html page

    I have a page at http://www.iel.nzco.net/100/index.html with a java script box in the middle. The script runs a text around an image, but the page always shows the grey box until the image and the java class files download. Is there any way that I can hide the grey java box until the java stuff is loaded then "reveal" the image. I have tried using a layer with the star background in it but the grey box still shows up. Any ideas you may have will be appreciated

    Hi raypuddy,
    I have found only one example in a book I own "Java 2 - The Complete Reference" by Shildt and Naughton. Essentially it has to be performed in the init() method:
    public void init() {
    String s = getParameter("bgcolor");
    if(s != null) {
    Color color = new Color(Integer.parseInt(s.substring(1), 16));
    setBackground(color);
    getParent().setBackground(color);
    getParent().repaint();
    ... etc.
    The approach is to get the background painted ASAP and defer other class loading until after the Applet is up and running. Under IE there will still be some user feedback of the Applet loading (spinning globe, status line).
    IMHO it is a lot of extra effort for little esthetic value.

  • Referencing a "locally installed" Java applet from a server-based HTML page

    How does one reference a "locally installed" Java applet from a server-based HTML page (i.e. via the applet, object, or embed tags)? I have seen references in documentation that this is possible, but I have not seen any examples. I have tried a few things, but nothing seems to be working.
    Some background...
    I'm working on a web site that aggregates Internet video. For many users, I would like the site to work "without" requiring Java to be installed (or any prompts, etc.). This version of the site allows users to stream videos directly over the Internet and does not require any sort of access to the local system.
    However, in addition, I have a download manager that can be installed on the local system. Currently, it's a Windows-based "service" that is always running in the background, downloading files, etc. (with plans to later support other OSes).
    My dilemma is trying to communicate between my web site running in the local browser (executing JavaScript code) and the download manager. I call this component the "gateway". I need the gateway to be able to do the following:
    1) Pass user credentials from the web browser UI to the download manager (so it can communicate with my servers).
    2) Check the status of downloaded videos
    3) Launch a local media player (such as Windows Media, QuickTime, etc.) (or perhaps tell the download manager to launch the media player).
    Under Windows XP, I have an ActiveX control that can do these things. It communicates with the download manager via reading/writing to a shared XML configuration file.
    Unfortunately, under Vista and IE7 Protected Mode, ActiveX controls have become very restricted and my gateway no longer works. As such, I am looking at using Java for the gateway (also giving me the additional benefits of supporting additional browsers and OSes).
    From my understanding, I believe I can created a "face-less" Java applet, whose methods can be called from JavaScript. Ideally, I'm thinking I could install the applet onto the local system at the same time the download manager is installed. This would give the applet the security permissions it needs to communicate with the download manager.
    Thanks for any help and suggestions!

    Hi,
    Put the .jar file and the .class file in the path mentioned in one of the aliases in the plsql.conf file like /images or create
    a seperate directory and create an alias like /applets "path" in the plsql.conf file.
    <html>
    <body>
    <applet code=com.chartapplet.chart.BarChartApplet
    codebase=/applets/
    archive=/applets/chart.jar width=300 height=200>
    <param name=background value="white">

    Hope this helps.

  • A tree-view in HTML page with nodes generated with java script in run time is not visible in the UI Automation Tree. Need Help

    I have a HTML page with an IFrame. Inside the Iframe there is a table with a tree view

    In UIA, i am able to traverse till the tree view but not able to see it.
    I have used the TreeWalker.RawViewWalker Field to traverse the node from the desktop Automation.RootElement. 
    I tried to use AutomationElement.FromPoint method to check whether i am able to get that element. Fortunately i was able to get the automation element. 
    i tried to get the path to root element from the node element using the TreeWalker.RawViewWalker. I was able to get the parent path to the root element.
    But trying the reverse way like navigating from root element to tree node, was not getting the element for me. 
    Please help me with suggestions or inputs to resolve this issue. 

    Thanks Bernard,
    It works fine with JInitiator but not working with
    the JPI. For JPI what settings I need to do ??hi TKARIM and Bernard, i am having similar problem even with the Bernard's recommended setup. could you post the webutiljini.htm (i presume you are using config=test) ?
    i am actually using jinitiator 1.3.1.28 with Oracle HTTP Server of OAS 10gR2) calling Forms Server 6i (f60cgi). After setting up according to Bernard's recommended setup steps, the java console showed that it loaded the icon jar file when it could not read the form, but it skipped the loading of the icon jar file once it read and started the form. How do we specify in the form to pick up the icon from the jar file instead from a directory ? Or do we need to specify ? Any ideas ?

  • How to get the source code of an HTML page in Text file Through java?

    How to get the source code of an HTML page in Text file Through java?
    I am coding an application.one module of that application is given below:
    The first part of the application is to connect our application to the existing HTML form.
    This module would make a connection with the HTML page. The HTML page contains the coding for the Form with various elements. The form may be a simple form with one or two fields or a complex one like the form for registering for a new Bank Account or new email account.
    The module will first connect through the HTML page and will fetch the HTML code into a Text File so that the code can be further processed.
    Could any body provide coding hint for that

  • Java Applet in a HTML page: failing with PLS-00306: wrong number of args

    We are trying to use a Java Applet in a HTML page. as our system needs to be able to retrieve a predefined set of data from a third party system that uses Dynamic Data Exchange Protocol (DDE) and are encountering errors from APEX and in IE itself.
    We are using JavaDde from www.nevaobject.com that enables our Java applet to interact with Windows applications (Third Party System) using DDE.
    This functionality is currently used in our Web Form 6i application and we are trying to use the same in the new ApEx application.
    We are using ApEx version : 2.1 and actually aer encountering 2 problems:
    Problem 1: ApEx failing with PLS-00306: wrong number or types of arguments in call to 'ACCEPT'
    Problem 2: IE crashes if Applet used in a complex page with several regions (1 Context, 4 Report Regions, 2 level Tabs, Links)
    This problem does not occur in the page where there is only applet and one region. In the case of complex page the IE crashes if the page is reloaded
    Test scenario:
    1- Create a simple page with the HTML region.
    2- Define the Source of the above region as follows
    <OBJECT CLASSID="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93"
    CODEBASE="http://java.sun.com/products/plugin/autodl/jinstall-1_4-windows-i586.cab#version=1,4,0,0"
    WIDTH="1"
    HEIGHT="1"
    ID="simpleApplet"
    NAME="simpleApplet">
    <PARAM NAME="code" VALUE="simpleApplet.class" >
    <PARAM NAME="archive" VALUE="simpleApplet.jar" />
    <PARAM NAME="type" VALUE="application/x-java-applet;version=1.4">
    </OBJECT>
    3- Create a simple Java applet "simpleApplet" - for the test its enough if the applet will have just the init method printing out the mesage to the console
    4- Create a Submit Button (not redirect) in Region Header and create unconditional (do not set When Button Pressed property) Page Branch to navigate to another page (the page without the applet)
    6- Run the page and Submit -
    The error below is returned by the engine:
    In our case our applet is called ddeApplet - I do not know why is ApEx passing the Applet's ID down to the wwv_flow.accept method as a parameter

    "theArrow",
    It looks like whatever HTML you're including on your page is creating HTML input form elements inside the HTML form "wwv_flow". This form is posted to wwv_flow.accept, and of course, the PL/SQL procedure wwv_flow.accept doesn't know anything these additional arguments/form elements you're attempting to POST.
