I am trying to use ant to compile jwsdp's sample code. I've
installed jwsdp, set up environment variables and path, however
when I try "ant build" in the example code directory, it always
gives Exception in thread "main" java.lang.NoClassDefFoundError: and.
Can anybody give me some hints on how to fix this problem?

Not JAVAHOME, it should be JAVA_HOME
Windows:
C:\...\> set JAVA_HOME=...
C:\...\> set ANT_HOME=...
C:\...\> set PATH=%JAVA_HOME%\bin;%JAVA_HOME%\bin;%PATH%
C:\...\> ant build
Unix (bash):
$ export JAVA_HOME=...
$ export ANT_HOME=...
$ export PATH=$JAVA_HOME/bin:$ANT_HOME/bin:$PATH
$ ant build

weird - it should be very simple to set up ant
I believe you tried
set PATH=%JAVA_HOME%\bin;%ANT_HOME%\bin;%PATH%
in your script,
maybe you can try set enviroment varibale through control panel? (just a try)
on the other hand, are you sure error is caused by ant not properly set up or
ant work fine but cannot find the files need to compile?
try to delete everything and re-unzip etc to a new dir and set ant_home, path
etc and try again - that's the last suggestion I can think of - if not work,

let me guess, you have 'C:\Documents and Settings' somewhere in the paths.
then, the cmd line will be like
java -classpath C:\Documents and Settings\blah org.apache.tools.ant.Main
as far as java is concerned, "and" is the main class name,
everything follows are arguments.
