[ILUG-BOM] [OT] J2EE vs LAMP

Hi, I have been trying to research pro's and con's of building web based Project Management application using J2EE and LAMP. The main factors I am considerting are:

1. Speed of developement 2. Salary of programmers 3. Security

I would appreciate if members who have used both technologies could shed some light on various issues. A few days back someone (I believe Philip) had mentioned that PHP does not have in-built security checks like Python. Could you please elaborate a bit on what those security checks are. Also has anyone on this list used PHPCollab and/or TrackPlus (An open source Java based Project Management software). Would appreciate some feedback on the stability of these 2 softwares.

Thanks
