No puedo ver mi form en el navegador con oracle 10G

Tienes que arrancar "Start OC4J Instance", que esta en programas- Oracle developer suite .. -> forms developer -> Start OC4J Instance, Tambien debes configurarlo para indicarlo donde estan las imagenes y los fmx y las propiedades del proyecto, el tnsnames, etc. Despues de arrancar hay una opcion para probar el funcionamiento: debe estar en :
Oracle developer suite .. -> forms developer -> Run a Form on the Web

Cordial saludo;
gracias por la respuesta. El start OC4J instance, si lo inicializo, pero tal vez lo que me falta es configurarlo para indicarle donde estan las imagenes y los fmx y las propiedades del proyecto, el tnsnames, etc. Esto que me dices no se hacerlo, talvez si me puedes colaborar.
Lo que si veo es cuando abro el OC4J me aparece:
Oracle application Server Containers For J2EE 10G(10.1.2.0.2) initialized.
Pero cuando ejecuto el form (ejecutar pantalla), cambia el mensaje del OC4J a:
FormsServlet init():
ConfigFileName:    D:\DevSuiteHome_1/forms/server/formsweb.cfg
testMode:    false
de antemano muchas gracias

Este D:\DevSuiteHome_1/forms/server/formsweb.cfg es el fichero de configuracion y
dentro de el esta la configuracion, si pones http://jeffersonpc:8080/forms/frmservlet?form=D:\modulo1\pruebaForm
Buscara la configuracion que tenga [default] y a partir de ahi tendras que poner :
userid=usuario/clave@nombreBD
Luego tendras que buscar en el directorio DevSuiteHome_1 el tnsnames. Ora y añadirle una entrada con la B.D., vienen ejemplos.
El siguiente manual te ayudara para configurar los demas parametros:

Saludos,
En el archivo formsweb.cfg me aparece la sgte configuración:

# formsweb.cfg defines parameter values used by the FormsServlet (frmservlet)
# This section defines the Default settings.  Any of them may be overridden in the
# following Named Configuration sections.  If they are not overridden, then the
# values here will be used.
# The default settings comprise two types of parameters: System parameters,
# which cannot be overridden in the URL, and User Parameters, which can.
# Parameters which are not marked as System parameters are User parameters.
# SYSTEM PARAMETERS
# -----------------
# These have fixed names and give information required by the Forms
# Servlet in order to function.  They cannot be specified in the URL query
# string.  But they can be overridden in a named configuration (see below).
# Some parameters specify file names: if the full path is not given,
# they are assumed to be in the same directory as this file.  If a path
# is given, then it should be a physical path, not a URL.
# USER PARAMETERS
# ---------------
# These match variables (e.g. %form%) in the baseHTML file. Their values
# may be overridden by specifying them in the URL query string
# (e.g. "http://myhost.mydomain.com/forms/frmservlet?form=myform&width=700")
# or by overriding them in a specific, named configuration (see below)
