images in java applet not showing

N

Navodit

I am working on a collaborative whiteboard application. So I have this piece
of code which is supposed to be using 2 jar files. I have been told that the
jar files (whiteboard.jar and collab.jar) work fine. However when the
whiteboard is displayed then the images of the icons (New, Close, draw line,
draw arrow etc) dont show up even though the whiteboard works perfectly
fine. Even the tooltip text can be seen when the mouse is placed over the
icons and I can perform all the functions required of the whiteboard. My
question is:

What could be the reason for the images of the icons not showing up ?

The images are not included in the jar file but are in a folder called gifs
which is in the same folder as the jar files. I tried including the images
in the jar file but that still did not work !
The code that I use (in a .asp file) to invoke the applet is as follows:




<OBJECT classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93" width="600"

<NOEMBED> -->
</COMMENT>

Can anyone suggest why this could be happening ? Or take a educated guess as
to where I should look for the error ? Any help/hints would be appreciated.
Thanks....

How are you attempting to read the images ?

Personally I'd put them into the jar file and read them from there, perhaps
http://java.sun.com/docs/books/tutorial/uiswing/components/applet.html#images or
http://www.rgagnon.com/javadetails/java-0240.html might help ?

I am using a pre Java 1.4 plug-in in my code. Does that make any difference
? In particular I am using Java 1.3 plugin... Also if I look at the Java
Console it does not show any error which means that it is able to locate the
image but during display instead of showing the image icon it is only
showing some buttons ... Any idea what cd be going on ?
