...upon choosing this product. Not only will it improve your health,
and enhance your general spirituality, it will also clean the bath, cook
you breakfast, take care of the children, end armed conflict and
invigorate the look of your web page.
You should be careful to check that your unzipping program has named
the files correctly. Some DOS programs will name according to the old
8.3 format, rename .class files "*.cla". You can rename
them by opening up a DOS window and typing:
It may also be possible that some of the graphics files included in archive have also be renamed. All of their names should be spelt with
lower case letters.
The Gallery Example
NB: If you cannot see an applet above, then
you may need to extract more files from the .ZIP archive before reading
The code which produces the above is:
<applet code="LakePanel" width=250 height=450>
<param name="image" value="doodle.jpg">
Paying for the Applet
There is NOTHING to pay. The applet is completely free. However, if you make a donation ($5 - $10?) to Ty Hafan, Children's Hospice of Wales, which is a charitable appeal formed to build, equip and run a Children's Hospice in
Wales to provide care for terminally ill children, you can consider your applet well-and-truly registered. Click here for details on how to make a donation.
Of course, if you really think that you can't get through the day without letting me have some cash (oh botheration... all right then...) I would appreciate it if you clicked on one of the discussion group adverts and set up a Nerdworld discussion group. It's free, only takes a minute and I get 50 cents every time it happens (Aha! I will have enough money for that
Nuclear Powered Set of Nasal Clippers yet!)
Using LakeDoodle in a web page...
To include in a web page, you should copy all class files into the
same directory as the web page and then insert an <APPLET...> tag into the page, e.g.
<applet code="LakePanel" width=250 height=370>
<param name="image" value="1.jpg">
The following parameters can be passed to the :
- The file containing the doodle image
You will need to set the height of the applet to 1.8 * height of doodle image.
I'd suggest you put the class files in the same directory as the page on
which it will appear. If you want to move it elsewhere
then use the "CODEBASE" option to point to the appropriate directory.
Some implementations of Java will not allow you to put the .class file in one
subdirectory and the image file in another. If the try it might cause a security
- If you make the applet too large then you will notice a strip
appear at the bottom of it as the waves lap backwards and forwards.
The solution is to make the applet a bit smaller...
- Some older versions of Netscape 3 will not let applets use some
JPG formats. If you notice that your applet works on Netscape 4
and IE 3 - 4 but no image appears on Netscape 3, this might be the
Why won't the applet work off my hard disk?
Some web browsers have trouble opening applets straight from a hard disk.
I have noticed this happen with Internet Explorer 3 and Netscape 4. Once
you have loaded the class file and the web page onto your web site you
should find it works OK.
Why does my web page say "Class Format Error"?
Class files are binary files, just like image files are. Binary files
contain more information than text (also known as ASCII) files do. If
you transfer class files as if they were ASCII files then they will
lose this extra information and will become corrupted. How do you
transfer class files as binary files? You should transfer them in
the same way that you transfer image files.
Why does my web page say "Class Not Found"?
This is a very common problem. It may be because of one of the following:
- You have not put the class file onto the web site
- You are not calling the file with the correct name
(rename to use the same combination of upper- and
lower-case letters as your class file)
- Your transfer program has changed the name. This
does happen. Some programs will shorten the ".class"
extension to ".cla". Other will change the case of the
letters to either all uppercase or all lowercase. See
if you can change the options on the transfer program
to stop it doing this.
- You have include a "codebase=…" clause inside your
<applet…> code in your web page. "codebase=…" tells
the browser to look some place else for the class file.
- Some other reason I haven't thought of :-)
Examples from the Web
Linking to my site
If you use this applet then it would be nice if you gave me a link
by copying the image:
(this is the file "dglogo.gif" in the .zip archive)
into the same directory as your web page and then pasting the following
into your page.
<a href="http://www.demon.co.uk/davidg/spigots.htm" target="_top">
width=88 height=31 border=0></a>
It will put a little button on your page that will link through to my Java Spigots
It is only a request: feel free to omit it.
Remember that if you are transferring the .class file to
another machine with FTP, you should set the 'binary' mode on. Failure
to do so will corrupt the file and give rise to a "Class Format" error.
If you still have trouble getting the applet to work and you have
tried all of the possible solutions listed above, then feel to
contact me, remembering to include:
A precise description of the problem (do you just
get a grey rectangle, or an error message etc. etc.)
The URL of the page containing the applet (that's
the actual page - not just the front page on your site)
These two pieces of information will make it a lot easier for me to
solve the problem. I cannot guarantee that I will be able to
respond to all messages (there's only so many hours in the day...) but
sending the URL of a page that doesn't work will greatly increase the
chances of getting an answer.
Remember to keep a look out at
my web site
for new applets.
