For 2023 - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.
Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!
I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
Finding your java program - the CLASSPATH variable
When you run a Java 'program' (strictly, the main method of a class), it looks for that class in a file with the name given and with a .class extension in the places listed in the CLASSPATH environment variable
. Failure to have the right CLASSPATH set results in a spectacular series of error messages!
[trainee@easterton ~]$ java Nother
Exception in thread "main" java.lang.NoClassDefFoundError: Nother
Caused by: java.lang.ClassNotFoundException: Nother
at java.security.AccessController.doPrivileged(Native Method)
[trainee@easterton ~]$ export CLASSPATH=/home/trainee/a9tom
[trainee@easterton ~]$ java Nother

CLASSPATH may include a series of : separated directories (; on windows)
CLASSPATH may contain the names of jar files, in which case the class will run straight from the jar (written 2009-04-02)
