Just taking note reminder for myself, it's about how to configuring Apache 2 HTTP Server (Not OHS come with Compl CD of Oracle Database) as a front end HTTP Server for APEX 4.0 installed in Oracle XE 10g.
Just follow the step as explain below:
Install Apache 2.2 Server (Source can be downloaded from http://httpd.apache.org/download.cgi) installed with listening port configure at 8888
Install Oracle XE 10g Database (Download from http://www.oracle.com/technetwork/database/express-edition/downloads/index.html) installed with listening port configure at 7777
Install APEX 4.0 (Download from http://www.oracle.com/technetwork/developer-tools/apex/downloads/index.html)
After those development tools installed last thing to do is Configure Apache2 to become front server and static images server for APEX 4.0 then do the following steps:
Enable/Activate module mod_proxy, proxy_http_module with LoadModule Directive. Configuration example:
LoadModule proxy_module /usr/
