Troubleshooting.
I cannot make the applet show more
than five pictures
I can't
view pictures when running the applet locally on my harddrive
Some pictures
don't show up when viewing them with the applet
I cannot
load a picture from the http://<domain>
I changed the image information but
the applet doesn't seem to care
I cannot make the applet show
more than five pictures
This limitation only exists in the demo version
Purchase the full version and you will be able
to show
more than five pictures.
I'm sorry I have to limit the demo this way,
if I could only
trust everyone to register the applet after ten
days I would
gladly remove the limitation.
I can't view pictures when running
the applet locally on my harddrive
You should be able to view pictures using the applet locally if the
pictures is in the same
directory or a subdirectory to where the applet is, note that both
the classfiles, the page
with the applet and the indexfile ( if different from the page with
the applet ) should be in
the same directory as the pictures.
Netscape 4.5:
I have myself noticed that after installing certain other programs
on your computer Netscape 4.5
may fail to run the applet properly ( pictures won't load ).
To solve this problem when using Netscape 4.5 locate the prefs.js file
located in
<netscape install dir>/users/<your username>/prefs.js
close Netscape if it is running, then open the file in a texteditor
and add these
lines to the end of the file:
user_pref("unsigned.applets.low_security_for_local_classes", true);
user_pref("signed.applets.local_classes_have_30_powers", true);
user_pref("signed.applets.low_security_for_local_classes", true);
user_pref("signed.applets.verbose_security_exception", true);
If you cannot find the file do a search for it on your system.
Restart Netscape after saving the prefs.js file, this will make all
local java applets
trusted, note that this will affect security on your machine if you
download other applets
and use them locally, however it will not affect security when
viewing java applets
through the internet.
If the viewing window show up as a small window
with just the label
on it then the picture probably didn't get loaded,
make sure the picture exists
and that the page with the picture information
has the correct urls ( relative or
full urls' ). You may have to restart the browser
after changing the page to make it load
the the new information.
If the viewing window is resized and you see a
blank area with no picture then the loaded
picture is probably a gif animation, the applet
does not support gif animations.
This is because of the security "sandbox" a java
applet executes within,
you cannot make the applet load pictures from
another domain than the domain
the applet is on.
If you want to load pictures from another server
( domain ) you have access to you must set
up the applet ( classfiles ) on that server and
then modify the applet tag on the page
on the server where you want to use it:
<applet
codebase="http://the_server_the_applet_is_on/applet_dir/"
code="Viewer.class"
width=100
height=80
>
<param name="refresh" value=10>
<param name="indexfile" value="http://the_server_the_applet_is_on/applet_dir/indexfile.html">
</applet>
Note that the codebase points to the classfiles on the other
server and that the indexfile parameter
points to a file with image information on that same server.
I changed the image information
but the applet doesn't seem to care
Your browser has probably cached your webpage,
clear the cache and restart your webbrowser
to force it to load the changed page or pictures.
