Oracle Forms

hello all :)

i wonder how to make oracle forms read the ttf fonts installed on linux

i cant open the canvas since it has a font thats not read by oracle "Arabic transparent" then it throws error *"VGS-1313: Font lookup failed"*
i read that the reports builder read fonts by exectuing xlsfonts to get available fonts , but forms dont really show all the fonts just some that come with the devsuite

anyway so i made this form on windows with font arabic transparent , and when i got that error i thought about installing it on linux and then did , but same error ,
also , i tried to add it to uifont.ali and no luck , so if anyone have any idea please share it :)
