Pass Color Param to Java Applet

I am trying to get 2 different parameters (from an HTML file) and use these to decide background colors for 2 JLabels (with the applet able to display a choice of colors from: red, green, blue or yellow). I have tried getting the color and setting to a string e.g:
String myCol1 = getParameter("col1");
But I am not sure how to parse this to a color so that I can use:
jLabel1.setBackground(new java.awt.Color(col1));
Any ideas on how to do this and also how to be able to choose from a selection of colors?

Ok I have now saved the parameter as a String and created a new colour (depending on which color is passed from the HTML) however, it is still not displaying the background for the jLabel correctly. Any ideas where I am going wrong? Here is a sample of what I have:
        String myParaNum = getParameter("col1");
        if (myParaNum == ("Yellow")){
           mynewcol = new Color(255,255,0);
        jLabel1.setBackground(mynewcol);
     jLabel1.setOpaque(true);
        jLabel1.setText("Hello");
        contentPane.add(jLabel1, java.awt.BorderLayout.CENTER);
  private javax.swing.JLabel jLabel1;
  private javax.swing.JLabel jLabel2;
  private Color mynewcol;
  private Color mynewcol2;     
}

  • JAVA Applets from Adobe Flash/MS Silverlight?

    SAP has recently announced that it will no longer support
    invocation of JAVA applets directly from its "WebDynproABAP" or
    "WebDynproJava" applications. (Until recently, SAP supported an
    "iframe" UI element that could be used to run JAVA applets from
    within WebDynpro applications - soon this will be only doable in
    frames within SAP's portal via "client-side eventing".)
    However, SAP will be supporting invocation of Adobe Flash and
    MS Silverlight from within its WebDynpro Applications.
    So here's my question.
    From an SAP WebDynpro application, I want to pass parameters
    to the JAVA applet "JMol" and have it run in a separate frame.
    Since I will no longer be able to call this applet directly from
    the SAP WebDynpro application, I'm wondering if I could pass
    parameters to Adobe Flash or MS Silverlight and have Flash or
    Silverlight invoke the applet for me with the correct parameters.
    (I would still only want two frames - the one that the SAP app is
    running in and the one that the JAVA applet winds up running in.)

    This link:

    says that javascript can be called from Flash
    So is it as simple as invoking the Java applet from the
    javascript ?

  • Passing an Array to an Applet using PARAM

    Is it possibly to pass values as an arrary to an applet from the HTML page. Like so:
    <param name="images" value="'/archives/4/6-26-1/10/04-01-06-26-10-00-07-00.jpg',
    '/archives/4/6-26-1/10/04-01-06-26-10-00-17-00.jpg',
    '/archives/4/6-26-1/10/04-01-06-26-10-00-27-00.jpg',
    '/archives/4/6-26-1/10/04-01-06-26-10-00-37-00.jpg',
    '/archives/4/6-26-1/10/04-01-06-26-10-00-47-00.jpg'">
    And how would I be able to stick that in an arrary inside my java applet?

    so your parameter list would look like this:
    <param name="images" value-"/archives/4/6-26-1/10/04-01-06-26-10-00-07-00.jpg,
    /archives/4/6-26-1/10/04-01-06-26-10-00-17-00.jpg,
    /archives/4/6-26-1/10/04-01-06-26-10-00-27-00.jpg,
    /archives/4/6-26-1/10/04-01-06-26-10-00-37-00.jpg,
    /archives/4/6-26-1/10/04-01-06-26-10-00-47-00.jpg">
    and in your applet you do this:String allImages = getParameter("images");
    StringTokenizer st = new StringTokenizer(allImages, ",");
    String[] imageNames = new String[st.countTokens()];
    while (st.hasMoreTokens()){
    imageNames[i++] = st.nextToken();

  • Passing Variables From PHP to Java Applet ?

    I took one page of a project which was written entirely in PHP, and translated it into a JAVA applet, so as to support better GUI funcitonalities (immediate calculation and display of Time/Billing data, on LostFocus events...stuff like this).
    In any case - I need to pass four variables from the php scripts, to the Java Applet. I had initially, written them out from the php scripts to an html file on the server, and read them in from the applet doing something like this:
    .     this.m_TheURL = new URL(url);
         InputStream in = m_TheURL.openStream();
         DataInputStream data = new DataInputStream(new BufferedInputStream(in));
         while ((unparsed = data.readLine()) != null)
    // parsed the strings here and got my variables
    The URL I read from, was the same file I wrote out to from the PHP scripts. This worked fine - until I told my boss about it, and realised that this wasnt going to work - because the applet updates a MySql database, and issues regarding multiple users became apparent.
    The Applet has to get these variables from the previous PHP page, the same way it had - before my applet was an applet, and it was just another PHP script page.
    The PHP pages are passing variabes using CGI, and a PostGet function. My applet has to do the same thing.
    Anybody know how I can do this - safely ?

    Updated some code... in case people wanted to use it....
    <?php
    class JavaApplet {
         var $param;
         function setParam($name, $value) {
              $temp1 =  array("name" => $name, "value" => $value);
              $this->param = array_merge($this->param, $temp1);
         function delParam($name) {
             foreach ($this->param as $key => $value) {
                  if ($key = $name) {
                       unset( $this->param["$id"]);
         function echo_html() {
              echo '<applet code=TimeEntry.class width=600 height=90 >';
              foreach ($this->param as $value) {
                   foreach ($value as $key => $value2) {
                        echo '<param name="' . $key . '" value="' . $value2 . '">';
              echo '</applet>';
    $applet = &New JavaApplet;
    $applet->setParam("name1", "value");
    $applet->setParam("name2", "value");
    $applet->setParam("name3", "value");
    $applet->echo_html();
    ?>

  • Java Applet Background Color Problem on Internet Explorer

    Hi,
    Please check out the following URL:
    http://www.utopiainteractive.com/clients/AkonFinal/glossary.htm
    The menu bar is writting in Java Applet. If you scroll down the page, and scroll back up, I see white background as I scroll back up. It happens only on Internet explorer. Neither Java Applet nor HTML Body bg color is white. I am kinda lost, and any help would really be appreciated.
    Thank you and look forward to hearing from someone soon.
    Sachin

    Hi,
    Well I used HtmlConver utility to generate applet html code, so I assume nothing is wrong with Object tag. Do you know what could cause this problem on Internet explorer? To be honest, I spent last couple of days, but I am just lost. It absolutely works fine on Netscape.
    Thanks,
    Sachin

  • Best way to have signed applet pass parameters to local Java applicaiton

    Hi all, I have a web application that needs to interact with a camera on the local computer. I first created an applet but the time to start the camera up was un acceptable. Now I have converted the applet to an application on the local user's computer that keeps the driver running. I call the applet from the web page to pass information to the local applicaiton that will take the pic and then load it into a database using jdbc.
    The question is how to pass the parameters from the applet to the java applicaiton? Iwas thinking of using network sockets to have the local app listening and then a signed aplet that will connect to the port and pass the parameters (just text fields).
    Has anyone already done this and have a better method?

    It will be working only on a computer, where JRE is installed. I assume that if someone has installed JRE nowadays, it will be "higher" version than is needed for your applet.
    L.P.

  • COMMUNICATION BETWEEN JAVASCRIPT AND JAVA APPLET: US$20 AWARD FOR SOLUTION!

    COMMUNICATION BETWEEN JAVASCRIPT AND JAVA APPLET PROBLEM (Easy Filter Java Applet) -
    US$20 TO ANYONE WHO CAN RESOLVE THE PROBLEM
    To forum visitors:
    I am prepared to pay a standard shareware fee of US$20 to a user who can resolve this technical problem.
    If your advice resolves the problem, I'll forward the payment to your postal address (include your
    address with your reply, and also your email address)
    I am attempting to enable a HTML button (using Javascript's onClick command) to directly input a number into one of the parameter text boxes in the Easy Filter Java applet (ie, enter a new color value number in the text field of the standard Colors Multiplicator Filter interface).
    The applet is Freeware and can be downloaded at: http://www.javazoom.net/applets/easyfilter10/EasyFilter10.html
    (It is a very effective bitmap display and editing utility)
    To achieve this, I am trying to access the part of the applet that defines and sets the textbox. The text box is defined in the .class file by accessing the parameter details in the genericfilter.txt file (accompanies the .class files). I need to access 'private String appletInitialize()' and then one of the 'textFieldParameters' which sets the textbox.
    I understand the basic syntax for referencing the applet:
    document.appletname.setString("An example"). However, accessing the text fields in this applet is more complex!!
    Please can you recommend the correct Javascript syntax to achieve communication with the applet.
    Thank you for your kind assistance.

  • 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">
    </body>
    </html>
    Hope this helps.

  • 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.

  • How to pass argument to the Java Plugin JVM w/o using the Control Panel?

    I want to deploy an applet to be loaded by the Java Plug In
    and fix some settings of its Java Virtual Machine.
    The JPI Control Panel offers two ways to pass arguments to the JVM,
    none satisfactory.
    1. while interactive via the Control Panel Window.
    This cannot be a solution for a deployed applet.
    or
    2. by editing the system generated file that stores
    the settings of the Plugin Control Panel, using a property
    named javaplugin.jre.params.
    The problem with this method is that if forces to access
    and edit this property file which is stored at various locations
    depending the client platform. Then, it may collide with other
    settings for other applets.
    Is there a way to pass the arguments to the JVM
    from within the html file?
    Has anyone found a solution to this question?
    JPS

    I am interested in this issue as well.
    Did anyone find a reliable way to specify the runtime parameters that should be used by the Java Plug-in in order to execute a given Java applet?
    I believe a good place to specify these runtime parameters would be the applet's JAR manifest: only digitally signed applets should be able to set the desired runtime parameters...
    Any comments / suggestion would be greatly appreciated.
    Regards,
    Marco.

  • Java Applet won't load when a JavaScript variable "this.Document" is used.

    Hi,
    Creating a "this.Document" variable within JavaScript interferes with some versions of Java. So far it breaks on the following versions, using IE7 on Windows XP:
    * JRE 6.0 Update 7
    * JRE 6.0 Update 6
    * JRE 6.0 Update 5
    * JRE 6.0 Update 4
    [Due to time constraints JRE 6.0 to JRE 6.0 Update 3 were not tested]
    * JRE 5.0 Update 22
    [Due to time constraints JRE 5.0 Update 16 to JRE 5.0 Update 21 were not tested]
    * JRE 5.0 Update 15
    [Due to time constraints JRE 5.0 Update 1 to JRE 5.0 Update 14 were not tested]
    * JRE 5.0
    The following HTML demonstrates this problem when you have any of the above versions of Java installed:
    <html>
        <head>
            <title>Java Bug</title>
            <script type="text/javascript" language="javascript">
                this.Document = 'string'; // Remove this line to get it to work again
            </script>
        </head>
        <body style="background-color:black">
            <applet id="testVM" alt="Something is wrong. Java is not working."
                codebase="http://www.java.com/applet" code="testJava2_1/TestVMApplet"
                archive="TestVM2-test.jar" width="500" height="280">
                <param name="locale" value="en" />   
                <param name="titleSize" value="22" />
                <param name="subtitleSize" value="18" />   
            </applet>
        </body>
    </html>The page only displays a white box where the Java Applet should be. If you then remove the "this.Document" variable or simply rename it to something else then the applet loads without problems. Normally I would just use a different variable name but the variable name is placed within the Mootools JavaScript Framework and is not easily changed without forking my own project.
    Does anyone know why this happens and if it can be fixed without having to update to the latest version of Java?
    Thanks

    'this.document' is a predefined variable that defines the URL source of the current page. If you are referring to the predefined variable that provides access to the Document Object Model then I believe you are mistaken, that is 'window.document' or just 'document'.
    EJP wrote:
    Your name either conflicts with that or is getting confused with it somewhere.The 'document' variable is a parent of the window object e.g. 'window.document' but my variable has the context of 'this'. That means 'this.document.URL' returns 'undefined' instead of the URL for the current page.
    JavaScript is also case sensitive so 'document.URL' is not the same as 'Document.URL', the last of which returns 'undefined'.
    If Java relealy was confusing my variable with the predfined one then I would expect the same behaviour if I were to use differnt variations of the variable. However the follwoing JavaScript doesnt affect the Applet in anyway:
    <script type="text/javascript" language="javascript">
        //this.Document = 'string'; // Remove this line to get it to work again
        this.document = 'string';
        document = 'string';
        Document = 'string';            
    </script>For some strange reason it only affects the Applet when 'this.Document' is used. Why would Java be affected in this way in the first instance? Even setting the 'scriptable' parameter to false doesn’t help:
    <param name="scriptable" value="false">Are there any other settings I am not aware of that could maybe prevent Java from loooking at the JavaScript?

    Use another name.As I mentioned in my original post this is not easily done, I can edit the source code on my own site but the code still remains unchanged on the Mootools JavaScript Framework website.

  • Help!!! Need Java Applet to work in IE

    I found some applets (text scrollers) from the sun site that i wanted to use. downloaded them, but they do not work in IE that does not have JVM. in IE that does have JVM it says 'Java 1.1 Required' where the applet should be. is there a simple way to get sun java applets to work with IE and the MS Virtual Machine? I can't require my site visitors to have to download extra toys/plugins...

  • Java Applet painting outside it's borders?!

    Hello all, I have a java applet that is painting outside of it's bordors in Firefox and IE, only when scrolling does this occur. I have been searching around and found a bug which was submitted in 2006 for the same issue but cannot see any resolution or further issues. I imagine there must be a workaround as this would be quite a major issue if it was always the case. It only happens when scrolling and the applet is being repainted. Any ideas?
    Thanks
    Dori

  • Thanksgiving Challenge - ListenUp Java Applet integration

    For those that like a Challenge... I came across this Java
    Applet that appears to be quite powerful to add recording and
    playing of voice audio files to a website:
    http://www.javasonics.com/downloads/
    I have not been successful in writing the coldfusion code yet
    that will read the information that is passed from this Java Applet
    with respect to sound file (wav), file name, and other fields that
    are in the form when created.
    This is the format of the use of the Applet that I would like
    to get working on the site:
    http://www.javasonics.com/listenup/examples/use_text_fields.html
    I look forward to anyone that can get this code working and
    how you did it with ColdFusion.
    Thanks,

    When I run their PHP version that works on a Linux System and
    the Java Applet debugger on this is the result from the time the
    file is handed off from the Java Applet to the PHP Code.
    Can anyone tell if the file is actually being written to the
    server then PHP is reading it from the server or is it just being
    written to memory and PHP is reading a variable or memory block for
    this data?
