Null Pointer Exception
|
The display area is just a gray box with no animation for a long time. When you move the
cursor onto the gray area, you see the message on the status line (screen lower
left):
Applet CoolBE exception:Java.lang.Null
Pointer.Exception
Why does this happen?
The problem may occur when you are running CoolBE both from your local
drive and from a web site. There is a conflict between cached and disk files.
How to Fix
- Restart your computer to refresh the memory. Then the files should
be loaded from the same location.
- Delete your browser's cached files. Use the browser option to Clear
Cache and Clear Memory.

Applet CoolBE can't start
|
The display area is just a gray box with no animation for a long time. When you move the
cursor onto the gray area, you see the message on the status line (screen lower
left):
Applet CoolBE can't start:class CoolBE not found
Why does this happen?
The file CoolBE.class has a wrong name or a wrong format.
How to Fix
- Make sure the CoolBE.class file is in the same directory as your HTML file.
- If you used a DOS unzip that chopped the name to CoolBE.cla, you can change
it back to CoolBE.class, and change the Engine.cla to Engine.class. Better yet,
download Winzip to unzip the files again.
- When you upload to your web site, make sure you uploaded the *.class files
as binary files.

the same cause and fixes.
How to Fix
You may have this problem using a 256 color GIF image. Try
converting the image to a full-colored JPG or JPEG format.

Netscape Problems
|
CoolBE has some problems with Netscape:
Netscape 4.0 prevents all Java applets to access local drives. It does give
a bypass though. Unfortunately, neither the prevention or the bypass works properly.
CoolBE sometimes can not start with Netscape from your local computer.
Netscape 4.0 also has problems displaying a image if the image is scaled. The image
sometimes shows in wrong color or shows blank.
Choose a method below to fix them:
Netscape 4.5, preview release now availble for download, has fixed these problems.
Download Netscape 4.5 PR to run CoolBE.
If you have Netscape 3.xx or Microsoft Internet Explorer, use that browser to run CoolBE locally.
Read the
Netscape security settings to understand the options and the risks, and use the
PrefWrangler to change your Netscape security settings to allow CoolBE to access local files.
You may like to
make CoolBE online instead.
