Help me please.

 I construct a simple applet under Jbuilder 2.0 C/S of which here is the
text source.
If I execute this applet in appletviewer of the JDK 1.1.6 all is OK.
If I want to execute this applet from the browser IE 4.0 on my server WEB I
get the following
message.

NoClassDefFoundError: borland/jbcl/layout/XYLayout

 My question is.  What are the class files that I must install on the
machine client,
on the server, and in what directories and how to define the CLASSPATH,
knowing that the
structure of the server WEB IIS 3.0 is D:\inetpub\wwwroot and that my applet
and my htm
file is in directory java [D:\inetpub\wwwroot\java]

He it would be possible to explain me in detail please.
