Oracle to Postgresql conversion

Hallo All,

Does anyone know how I can convert an application written with Oracle Portal (including Apache), Oracle packages,
procedures,functions, etc. and PSP (a mixture of  
PL/SQL and HTML).

One suggestion is that the new application could access PostgreSQL from within Apache using Java Servlet pages: if
therewere any tools to convert the code, then  
that would be fine, but I expect there are not. PostgreSQL  recommend PHP, but I think with Apache we must use the
secondchoice, namely Java? Is there a chance of  
using a front-end, or is that an expensive solution? I have no  worries about PL/SQL, because there are conversion
utilitiesavailable!
