Now, I am building serweb in openser. So, the client can register to become the member of communication in my openser that I have built. 1. Can "serweb" (from iptel.org) be used in openser server for building the webserver of the openser server? Or openser has it`s own webserver except "serweb"? 2.When I build serweb (from iptel.org), I have some problems. I do hope anybody can help me and give me a suggestion. Please.. The error message that I got from client browser is Fatal error: Failed opening required 'var/www/phplib/db_mysql.inc' (include_path='.:/usr/share/pear') in /var/www/html/serweb/user_interface/prepend.php on line 23 The contain of prepend.php that shows line 23 is require($_PHPLIB["libdir"] .
