J2ee tutorial 1.3 lesson 2

Question

I have been scratching around for this answer. I hope i'm in the right forum for this problem.
Let me say from the top that lesson 1 went off without a problem.
My error occured when I attempted to compile the modified BonusCalculationServlet. The compiler came back and tells me that bonus.calculation doesn't exist. Yet it compiles the files in that directory but not BonusCalculationServlet.
I've checked: Spelling, the positioning of the files, the path, import statements(I cut and pasted the example) and enviromenal variables.
So, anyone? Why wouldn't the servlet compile or rather why doesn't the compiler recognize the import statements.
Your asistance is greatly appreciated

Answer 1

With strong inference, I believe you are running into a situation like this:
[cjm@didi ~]$ javac TimerDemoClient.java
TimerDemoClient.java:10: package javax.ejb does not exist
import javax.ejb.*;
^...and likely you have more compiler messages after this because you later refer to classes contained within a package that is not in your CLASSPATH.
The explicit solution to the problem above is to append to my existing environment variable "CLASSPATH" the location of j2ee.jar (which contains the package javax.ejb.*)
To do it the old fashioned way:
bash-shell> export CLASSPATH=$CLASSPATH:/usr/local/SUNWappserver/lib/j2ee.jar
bash-shell> javac TimerDemoClient.java
If you were to edit your .bashrc, then you would need to start a new xterm before you would get the changes to your environment.
In Windows you would go to
Control Panel | System | Advanced | Environment Variables
Find or Add CLASSPATH, Click OK/Save and then, importantly, start a New DOS shell to compile from (your existing one will not pickup this change)
