Java program with Applet viewer error

Asked By Timothy Larach 20 points N/A Posted on - 10/03/2011

Hi,

I was executing a Java Program in one of the PCs in the office when I encountered the error message below.  The Java Program was running well in the other PCs. 

I am just a new Java programmer and so please help me on how to troubleshoot the problem in this one PC.

Appletviewer:

This program has performed an illegal operation and will be shut down.

If the problem persists, contact the program vendor.

Java program with Applet viewer error

This problem occurs when you have a conflict about the version of JDK (Java Development Kit) when installed during the CafeLite installation.

There are 2 fixes:

1. This happens if  your video card is set for more than 256 colors. If it is, then reset it to 256 colors. After resetting the colors, run the applets. This will immediately solve your problem.

2. If Fix 1 did not solve your problem then you can use this step:

  -Remove CafeLite from the system of your PC. Make sure that you are able to delete Cafelite environment variables from the     autoexec.bat file: 

    SET CLASSPATH=.;d:CafeLiteJAVALIBCLASSES.ZIP

SET HOMEDRIVE=d:

    SET HOMEPATH=CafeLiteJAVA

    SET JAVA_HOME=d:CafeLiteJAVA

 

After doing the following steps, just reboot your PC and everything work properly.
