forewords......

I have gathered quite some notes over the years while I toiled and sweat in projects working with technologies like J2EE, web applications, java, j2me, databases, operating systems, app servers to the more recent RFID and ajax stuffs... I had my fair share of frustrations trying to solve problems; wasting endless hours searching high and low for solutions etc.... recently i realise that my ailing brain is having problem remembering everything...so I better start writing them down somewhere...
