    Thumbs up Error Deploying Applet project in netbean to Tomcat

    Hello Team,


    I wrote a little applet application which accesses a database(oracle),It run fine within netbean IDE but if I try

    to run it on a browser(Html file) it does not connect to database. The applet is organized in a package(appletform) of two

    classes(appletform.java and cod.java).

    2. Also, How can I deploy this application to tomcat on my system using netbean IDE so that it can be accessed

    from a browser.

    my html file is show below
    =============================

    <HTML>
    <HEAD>
    <TITLE>Applet HTML Page</TITLE>
    </HEAD>
    <BODY>

    <!--
    *** GENERATED applet HTML launcher - DO NOT EDIT IN 'BUILD' FOLDER ***

    If you need to modify this HTML

    launcher file (e.g., to add applet parameters),
    copy it to where your applet class is found in the SRC folder. If

    you do this,
    the IDE will use it when you run or debug the applet.

    Tip: To exclude an HTML launcher from the JAR

    file, use exclusion filters in
    the Packaging page in the Project Properties dialog.

    For more information see the

    online help.

    I moved this thread to a more appropriate forum, as the Member Introduction forum is not the place for technical questions.
