and then compile using
c:\> javac -cp "d:\new folder" "d:\new folder\com\model\xyz.java"
does this compile on your system successfully?
i am totally confused..

why did i have to compile the xyz.java from C:\ ??? why didn't we compile it from D:\ like in the case of abc.java.. I know these are very basic things but i would like to know this through this discussion because i am starting to love learning through this discussion... So kindly help me out...

* The folder where my project is ServletsFolder whose path is---
C:\Program Files\Apache Software Foundation1\Apache Tomcat 6.0.26\webapps\ServletsFolder
*Inside the folder (ServletsFolder) i have a WEB_INF folder and a html form named form.html
*The WEB_INF contains a deployment descriptor (web.xml) file and a folder named (classes).
*the classes folder contains (com\example\web) and (com\example\model) where the web folder contains the servlet (CoffeeSelect.java) and the model folder contains the plain java class(CoffeeExpert.java) whom the servlet invokes.
the situation so far.... when i compile the plain java (CoffeeExpert.java), it gets compiled but the servlet doesn't compile

If you are using tomcat add servlet-api.jar to the classpath before compiling the servlet java file.

i created the same scenario on my system...but i m able to compile it successfully....i have simply copy and pasted your code... and your javac commands and all that...
and it got compiled in one go...
i am not able to understand why is it so...
create two classes in the same web-inf\classes\com\web and model directories... let the package and import statements be as such... but create empty classes....no methods no variables nothing...even don't extend HttpServlet and then try to compile... still if you are getting errors then...google is the best option i think...
it compiled... I mean the one you told me to do...

and by the way what did you mean when you said

THANKS A TON 
to everyone who participated in my matter.... I am very happy now and relieved as well...
. So I wanted to know exactly what is "-cp" and what was that "%CLASSPATH%;" thing all about.

Using -cp switch would override any entries you have set in CLASSPATH environment variable. Including it along with -cp switch would append new entries to it so that javac/java etc... will pick them all.

-cp c:\foo
means your entire classpath is the foo directory. You will even lose the . for current directory from the classpath.
If you use
-cp %CLASSPATH%;c:\foo
you are adding the foo directory to the end of the old classpath. The foo directory is now in addition to the old classpath.
