Just a couple of quickies
1) If I have a directory structure on a windows machine A/B/C and the java command resides in C and I don't have the CLASSPATH/PATH variable set. If I'm in the A directory can I go
B/C/java myJavaprogram ? I can't get it to work but it might be for another reason.
2) Can anyone recommend a definitive place to read up about CLASSPATH, PATH etc showing how to run/compile Java in certain scenarios?
TIA

a) No, it won't work. java doesn't go thru subdirectory like that.
however, you can use java -classpath b/c myProgram. -classpath indicates where to look for application classes and libraries.
NOTE: if you running packages, you have to use java a.b.c.MyProgram.
b) No sure, I don't remember where, I think thru trail and error can definitely help you learn more.

Welcome to JavaRanch, Graham VMead!
Regarding your first question, I'm not exactly sure of what you're trying to do. If you were to post the actual commands that you are trying to execute, things might be a little bit clearer. Also, what operating system are you using?
Regarding the second question, a good place to start might be our wiki. See http://test.javaranch.com/wiki/view?HowToSetTheClasspath
Good luck and I hope to see you 'round the Ranch!
