Linux Error:111:Connection refused & Linux Error:29:Illegal seek

Question

I have installed the rpm pack oracle-xe-univ-10.2.0.1-1.0.i386.rpm in Red Hat Enterprise Linux. I was able to install the rpm pack and am able to initiat sqlplus on the server and even run sql queries.
However i am facing the following issues:-
1) While browsing http://127.0.0.1:8090/apex for accessing the database home page i am getting the error message "The connection was refused when connecting to http://127.0.0.1:8090/apex" (i have mentioned 8090 as the HTTP port during configuration and this is the URL which was listed after the configuration).
2) I am unable to start the listerner service.
Please help me to resolve the above issues.
Following is the message while checking the listener status:-_

I had to re-install the linux server and install the oracle rpm again ... resulting in delayed reply.
Currently still i am unable to access http://127.0.0.1:8090/apex. The following error message is being displayed
"The connection was refused when attempting to contact http://127.0.0.1:8090/apex"
However now the listener service has started successfully.
