ora-12541 error message connecting to database through forms builder

I get the ora-12541 error message when I try to connect through forms builder. I've started the listener manually and the oc4j instance. I have no problems accessing the database through the Enterprise Manager Console or SQL Plus. I've checked the listener and tnsnames files and everything is seems okay. Any suggestions?

// *Cause: The connection request could not be completed because the listener
// is not running.

Is the listener running at the host and port that your tnsnames.ora file specifies?
