I am working on chapter 17 of the Professional Java Server Programming  
book and haven't had any 
problems up to this point, but I am having a hard time compiling and 
running packages.  I typed in the shell - start java 
businesslogic.DefectServer and java ui.defectform files exactly from the 
book,
 but the  program doesn't work.  I put the Line and Point files in the 
directory c:\tesis\asf\build_tables;c:\tesis\asf\bugtrackerapp; and I have 
windows xp 
c:/j2sdk1.4.0_01 and C:\Program Files\Apache Group\Apache2 
The programs seem to compile.when I run the command javac build_tables 
buildbugtracker_access.sql 
the compiler doesn't return any errors, just errors pointed in book and 
make file .class but when I run 
the program with start java businesslogic.DefectServer i get nothing (just 
a window open and close suddenly)  
and when I run java ui.defectform I get the dreaded Exception in 
thread "main" 
java.lang.NoClassDefFoundError 

I don't understand why this happens.  I set my classpath Environment 
variable, I run it with the -classpath option, I have tried almost every 
possible command line possibility but the program won't run.  What 
confuses me most is that it compiles.  

I dont know what kind of classpath have i to define???

Can anybody tell me what is happening?

Thanks,
