write a file in EBS apps server from a package?

Hi I have 11.5.10.2 EBS on 10g database.  They are in separate node - 1 apps node/server and 1 database node/server.

I have a requirement that I will create a package that is called by concurrent program.  The package is required to create 5 different text file and further process them.

In the past, I use utl_File to create these files.  But it always require create directory in advanced and the files are only created in database server/node.  Does EBS has any function available to create files in any directory in the apps server/node.  NOT database server?
