For 2023 (and 2024 ...) - 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 Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own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))
Writing a server in Java

My standard recommendation these days is that you don't write your own low level network code - but rather you use standard protocols and classes - i.e. that you use tried and tested ways of exchanging data. And on that basis, you'll find that our public training courses cover things like talking to web servers and services, using SQL servers from your programs, and so on.

But just occasionally, there's still a niche requirement to do something in low level code - perhaps because you're required to work with a protocol that's non-standard, or even because you need your own protocol for some reason. So, yesterday, I found myself doing a public Java course but out of hours also updating an old example that used packages such as java.net to write our very own server - a talker in a single file in Java. I've posting the example to our web site - [source code here] with updates including extra comments. There is also an older article that descibes it more fully [here].




If you came to this page looking for an article on running a Java Server such as Tomcat (a much more common requirement that writing your own), start [here]; that page is our short course description, and we would welcome you for training - however, you'll find links to many of the examples and a great deal of material from that page, even if you can't make it to Melksham, nor do you have enugh people to justify me coming along and giving a course at your office.
