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?

12541, 00000, "TNS:no listener"
// *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?
