Cannot Run Java Programs in Internet Explorer for Macintosh

• Microsoft Internet Explorer version 3.0 for Macintosh

SYMPTOMS

When you attempt to run a Java program in Internet Explorer, the Java program may not run correctly, or may not run at all. This problem may occurs even if Internet Explorer is properly configured to run Java programs.

CAUSE

This problem can be caused by either of the following situations:

• The Java program you are attempting to run is failing byte code verification.
• Your computer contains 8 MB of physical memory (RAM) and is low on system memory. Note that Internet Explorer requires at least 8 MB of physical RAM.

RESOLUTION

To work around this problem, use the appropriate method:

Java Program Failing Byte Code Verification

If you suspect the Java program is failing byte code verification, follow these steps to work around the problem:

1. Start Internet Explorer, and then click Preferences on the Edit menu.

2. Click the Web Content tab, click Don't Check Code in the Byte Code Verification box, and then click OK.

Computer Contains 8 MB of RAM

If your computer contains 8 MB of physical RAM and is low on system memory, quit any running programs that you are not currently using, or remove or disable any unnecessary control panels and extensions.

MORE INFORMATION

There are three types of byte code verification that Internet Explorer can be configured to use:

• Don't Check Code: Byte code located on your local hard disk and byte code obtained from a remote source, such as the Internet or a network drive, is not verified. Potentially harmful Java programs are allowed to run on your computer.
• Check Remote Code: Byte code obtained from a remote source is verified, but byte code located on your local hard disk is not.
• Check All Code: Byte code located on your local hard disk and byte code obtained from a remote source are both verified.
