Problem with starting Oracle HTTP Server

Question

I am in the process of installing Oracle Application Express Resease 2.2. After installing Oracle HTTP Server, I stopped it. But when I tried to start it, it failed. The following is the error message I got. Your assistance in helping solve this problem will be highly appreciated!
[oracle@linuxkm database]$ /u01/app/oracle/product/10.2.0/http_1/opmn/bin/opmnctl startproc ias-component=HTTP_Server

Here is everything from that file. I also attached the configuration section of the apachectl file below. The ORACLE_HOME points to the ORACLE_HOME for http, not the ORACLE_HOME for database. In addition, the httpd.pid file pointed by PIDFILE doesn't exist. Are there anything wrong with my Oracle HTTP Server installation?
