[answer to this non-question hopes to try and reduce the noise level of the recurrent "CGI vs JAVA" threads].
CGI and JAVA are fundamentally different, and for most applications are NOT interchangable.
CGI is a protocol for running programs on a WWW server. Whilst JAVA can also be used for that, and even has a standardised API (the servlet, which is indeed an alternative to CGI), the major role of JAVA on the Web is for clientside programming (the applet).
In certain instances the two may be combined in a single application: for example a JAVA applet to define a region of interest from a geographical map, together with a CGI script to process a query for the area defined.
