Newbie needs general help w/Java Updating

Hi,
I don't use Java (as far as I know) too often, but right now I've got Java 5_6 update on my computer. I've been told that's unstable and I should update to Java 6. I was also told I should remove 5_6 Update with add/remove programs before doing so. I was also told I should remove the three Java "objects" in the Downloaded Program Files Folder before doing so (which is an IE thing, right?). But I was also told to go and download Java 6 directly from the Sun site and install, but I'm not sure if that's necessary or the way I want to do it, because I have the option to check for updates in the Java Control Panel that comes up when I double click the Java icon in my Control Panel folder.
Questions:
1. The three java objects in the downloaded objects folder are in a folder that's part of IE, is that right? I don't use IE (except for Windows Updates), I use Firefox. So where are the objects kept for Firefox?
2. Do I really need to also remove these objects in addition to add/removing 5_6 Update? If so, for both IE and Firefox?
3. When I go to my Control Panel, there is an icon for JAVA. When I double-click this icon, a JAVA CONTROL PANEL opens up. If I remove 5_6 Update and those objects, will that also remove this control panel? The control panel was part of my system when I got my laptop.
4. If the Java Control Panel is retained, then why can't I just go to the second tab which is for Updates, choose "Update Now" and get the Java 6 update that way? (And this would be AFTER I remove 5_6 -- and any objects, IF that's necessary.)
It's my hope that I can just update to Java 6 (after removing the 5_6 update and objects, if necessary) by using the update feature in the Java Control Panel instead of downloading Java 6 from the Sun site. If this is not a good idea, I would like to understand why.
Any help is appreciated -- thanks!

Thanks for the post. So J2SE Runtime Environment 5.0
Update 6 (which is apparently what I have now) is
stable
It's reasonably stable. There are bugs in it, of course. There are always bugs in software. Unless you're having problems with them, however, you don't automatically need to update.
The list of changes between that release of Java 5 and the latest (1.5.11 at the time of writing) is given here:
http://java.sun.com/j2se/1.5.0/ReleaseNotes.html
, and it's false that it has security
holes that can be exploitedThat's a completely different question. I can't promise you that there are no security flaws that have been fixed since that particular update. However, unless you're running a server or downloading applets or otherwise running in a security constrained environment there's not much point in worrying about it. Again, if there is a specific reason for you to worry check the bugs and enhancement lists here to see if your concerns are addressed:
http://java.sun.com/javase/6/webnotes/index.html
Either way you don't update just because someone says you should unless you have reason to believe they know what they're talking about. I suggest you ask your original source to explain why they think you should upgrade and to provide you with the evidence to back up their assertions.

  • Another Newbie Needs Your Help!

    I'm going to try to make this quick, but there is an
    important backstory to my problem.
    I grew up living in Fullerton, California, until about 10
    months ago. I still call Fullerton my home and take pride in it.
    About 4 years ago, I started playing guitar; about 2 years
    ago, I started lusting over a Fender Stratocaster. Fender Musical
    Instruments was started by Leo Fender, a radio repairman who
    created the first mass-produced electric guitar in his workshop in
    Fullerton (coincidentally I went to the same high school he did as
    well).
    Health problems made him sell Fender to CBS; when he got
    better, he got with some friends and started the Music Man company.
    A falling-out with said friends resulted in him dissolving ties
    with the company. But then he got together with his long-time
    friend and descendent of the founders of his hometown, George
    Fullerton, and started G&L (George & Leo) Guitars. G&L
    still builds guitars in Fender's own factory, the original factory
    of Fender guitars, in Fullerton, even though Leo passed away in
    1991.
    A couple months ago I heard about G&L and, looking at the
    website, I realized that these were the exact guitars I'd been
    looking for--sooo much more than a normal Fender guitar (CBS has
    since taken Fender in different directions than Leo would have,
    even moving production to Corona, California) and still made in my
    hometown. The website, unfortunately, lacked pictures of the exact
    color and model of guitar I wanted, a similar problem I experienced
    on Fender's website. Having built upon my 12 years of experience
    and know-how with photoshop, I had taken a high-resolution photo of
    a Fender Stratocaster and had made custom shapes out of every piece
    of the guitar so that I could customize and colorize the thing to
    my heart's desire. But the shapes changed to G&L shapes once I
    heard of G&L.
    Well, after a little tinkering, I had my dream guitar, and
    posted pictures in the forum of G&L. Two days later the CEO of
    G&L contacted me with the offer of swapping a guitar for some
    webwork. I'm ecstatic! A $2000 guitar just for something I do as a
    hobby? Plus *******' resume material...
    Anyway, the Photoshop work is easy; but I don't want static
    pictures of my artwork on any website. Optimally, I wanted to
    figure out how to build a guitar customizer using Flash, and Mr.
    CEO is more than happy to follow my train of thought. Problem is,
    I've taken one college-level beginning Flash class but still feel I
    know nothing aside from being able to animate something, which I do
    using a USB pen-and-tablet to make mini-cartoons.
    So I've been google-searching macromedia flash tutorials
    looking for someone that can help me build a customizer.
    I know of a couple examples:
    DUBMODDER: VW Customizer
    MINIUSA: Build your own MINI Cooper
    Now I'm not afraid to work hard, and I have a great sense of
    an artistic, streamlined, and web-friendly style, as I've done web
    work with photoshop before. I also catch on with any computer
    program very quick; I took an 8-week college class in 3DS Max and
    completed it with the highest grade in the class and left my
    instructor with no doubt that I was one of the very few who didn't
    need to take the course over to pick up anything better.
    These are the two examples I have on Photobucket of my
    guitars; they're the same model, the only difference is body and
    headstock color. These are the two options I'm considering, though
    of late I've leaned towards the green:
    Translucent
    greenburst with matching headstock
    Translucent
    orange with black headstock
    Every individual component of the guitars is its own custom
    shape; so styling and coloring is a breeze, plus getting them up on
    the screen individually is a breeze as well. I just need to know
    how to get it so that through a series of menu bars, radio buttons,
    and checkboxes, I can include all the options available to someone
    who would be purchasing a guitar and have a realtime, interactive
    picture of the guitar displayed either below or to the right of the
    options bar.
    Oh, and another note: each of my pictures above is scaled to
    25% original size but uncompressed. Being vector graphics, everyone
    here knows how high they can be scaled without loss of detail.
    Thanks in advance, and if I get significant help, mention
    will not be forgotten to this forum and the significant
    helpers.

    Welcome,
    but if you want help, you really must avoid the thesis-style
    posts - not too many here have time to
    read a life biography as interesting as it may be - and after
    reading most of it I am still not sure
    what your question is - there's nothing specific in your post
    other than what brought you to this
    point in your career/hobby.
    I would suggest keeping your question very direct and to the
    point and in as few words as possible -
    many of us have clients and deadlines and not a lot of time
    to devote to answering questions. Take
    this as constructive critism only please - i read your post
    and still don't know what answer(s) you
    are looking for.
    (also helps to provide a descriptive subject sso when we scan
    the posts we can see the topic
    involved and know ahead of time if we can answer them -
    subjects that are general and vague like
    "Nebie needs help" tend to get skipped over by the majority).
    hope this helps.

  • Newbie needs JNI help

    the JNI tutorial speaks about creating a "shared directory" where a "dll" file is created and stored.
    How do i create this ".dll" file and store it into the shared directory ? ...

    Hi,
    Creating dll is outside the realm of Java programming. You need to use some language like C/C++/VB etc. Any good C/C++ IDE has wizards to help you create a dll. Use them. There is a free one at www.bloodshed.org called Dev-C++.

  • Newbie needs urgent help

    Hi guys,
    I need to create a function that returns as string, the path or location of the file it is in.
    for example:
    this function will be in a file called A.java
    A.java has the path C/MyDocuments/Jenna/java/A.java
    so when I run this function, it returns a string "C/MyDocuments/Jenna/java"
    I would really appreciate if someone could write code to help me understand how i can do this
    thanks

    You want the location of the source file (the .java file) from which the current class was compiled? You can't do that. (Unless you explicitly code it as a member variable of that class, which would be silly).
    Or do you want the location of the .class file? That can't be done completely cleanly or reliably, but you can sort of get it by searching all the elements of that class' ClassLoader's classpath, which you can't necessarily get for all classloaders.
    Whichever one it is, why do you think you need this?

  • Newbie Needs Template Help

    Ok I am a complete newbie to flash. I have read most of the guides provided and searched the forums but I honestly can't find an answer to my question.
    I have decided to use one of the templates provided with my flash pro cs5. It is the advanced album.
    My question:  how do I use it?  
    I know it gives me generalized instructions when it opens but for the life of me I cannot figure out where or how to put my photos in.
    I am using the template because when I try to make an album from scratch I also cant seem to get it to work right (the images just fly through on the preview)
    thanks in advance for the help!

    Hello wiccanluvr1988,
    To make photos show up in the 'Advanced Photo Template' you have to do the following steps...
    1.Store your project .fla file inside a folder.
    2.Put all your photos inside that folder that you want in the Photo Template.
    3.Now you have to go inside the actions frame of the template and change line 11 with this code below by adding your own photo directory.
    Line 11:
    var hardcodedXML:String="<photos><image title='Your Photo'>images/yourphoto.png</image><image title='Your Photo 2'>folder/yourphoto2.png</image></photos>";
    Simple Explained Form:
    var hardcodedXML:String="<photos><image title='Image title here...'>Put image directory here</image>
    /*Repeat this line of code with new photo directories to display more photos*/ <image title='Image title for 2nd photo...'>Image directory here for 2nd photo</image>
    </photos>";
    I hope this helped...

  • Spry Newbie needs some help

    It is the little things in life I was always told and all I
    am trying to do is to pretty much duplicate the form validation
    demo. However I am not even sure where to begin. I have created
    many forms and have had them submit and returned in an emial
    successfully but I am not quite sure how the Spry widgets work or
    how to apply them to an existing form or even a new one for that
    matter.
    Does the page have to be dynamic in order to use the Spry
    validation widget? Hopefully iy can be used on a static page. Are
    there any tutorials out there for creating a form in DW CS3 using
    the Spry validation widget?
    Thanks,
    Houston

    Hi,
    First of all, the Spry widgets works on static pages, so you
    don't necessary need to have a dynamic page.
    It is not to hard to make the demo from site, and I'll
    explain you the basic steps you should do to have these widgets
    working on your page. The css part, you can customize as you wish,
    the demo from site is just a customization.
    As I saw, you use Dreamweaver for creating this demo, so I'll
    give you the explanations for how to do it on DW.
    In a html page, add a form. Inside form add: a Spry Textfiled
    validation input (from the Spry tag), a Spry Select input and a
    Spry Textarea input.
    If you go in design view and select an widget, a blue border
    will appear and on the Property Inspector will appear all the
    properties you need to customize.
    To see exactly what does every property, please check the
    Dreamweaver help.
    This is the start to create you own form containing Spry
    widgets.
    Hope this help,

    I think I can make these calculations by first splitting the data into two rows. I'm trying to read this data from a text file but when I get to the end of the file I get a NumberFormatException.

    So I'd guess from that, that your program reads in all the data and does what you require.
    But Then it reads in an empty line i.e. ""
    You'll want to handle this in some way like:
         if( ! line.length() == 0 ) //Don't try and Interpret a Blank Line at all
                 scores = line.split(".");

         catch( NumberFormatException e )
                System.out.println( "Could Not Parse: " + scores[index]  );
         }As for the procedure to do what you want, well, I'm sure you'll get that.

    http://livedocs.adobe.com/flash/9.0/ActionScriptLangRefV3/.
    When in Flex builder 3, I cannot seem to import any fl.* packages.
    How do I get to this package???
    Also, I do not see any support for nested Data Grids... I
    have a REAL need to be able to nest one grid within another. Is
    there any way I can do this in Flex? I found some stuff about the
    AdvancedDataGrid component, but, I don't know where to look for
    information on its capabilities.
    So, any help would be greatly appreciated. Thanks,
    Stan

    Hi Stan,
    Here's the link to the Flex 3 feature introductions on our
    Adobe Labs site about Advanced DataGrid:
