Acceso a base de datos Oracle vía http
Estimados:
La presente pregunta va para los que sepan de Java y/o Oracle.
Mi empresa tiene un servidor RBDMS Oracle, al cual se accede mediante
navegadores.
Los que usan Win, no tienen problema. Se carga Java y el Oralcel
JInitiator 1.3.1_9 (jinit1319.exe).
Desde mi Debian, accedo a la pantalla de ingreso de la base, pero ahí se clava.
-----------
La máquina java reporta lo siguiente:
Java Plug-in 1.6.0_21
Usar versión JRE 1.6.0_21-b06 Java HotSpot(TM) 64-Bit Server VM
Directorio local del usuario = /home/usr129
cargar: clase oracle.forms.engine.Main no encontrada.

De java, no entiendo ni una línea.
El acceso a esa maldita base, me obliga mantener una máquina virtual
con XP, para poder acceder a la maldita base de datos.
¿Alguna sugerencia?
Dejo constancia de haber googleado en castellano, ingles y algo de
alemán, probado todo lo que encontré y sin resultados.
En varios lados he visto de "engañar" a Iceweasel modificando el
archivo ~/.mozilla/firefox/6a335aap.default/pluginreg.dat, pero no he
tenido éxito, pues al reiniciar el navegador, sobre escribe mis
modificaciones.
Escucho sugerencias.
Muchas gracias
JAP
