Since January 2002 (full-time since September 2002) I've been working with Java. Almost all the time I've been
developing Java EE (J2EE) applications, ie. I had a running Weblogic or JBoss instance on my box where I did all of testing
and debugging.
Below is a a brief list of major projets I've participated. Before reading it you may consider having a look at
a list of programming books I think are worth reading,
a list of my Java EE links, a my
technical blog.
