Hi,
Try this out since you state that you can get scilab working with java when
you are not using eclipse:
1) Bring up Eclipse and right Click on the project you are working with

2) Select 'Build Path'->'Add External Archives'

3) Change Directory to where the 'javasci.jar' file
is installed on your C drive and select the jar file.

The javasci.jar file should now be added to your project and all your
scilab commands in your java files and the import javasci.*; should be compiling
properly.

Hope this helps.

Regards,
Arthi
