Creating folder in pl/sql through Java in a network drive

Question

Hi there,
I am trying to create a folder in a network drive using Java with pl/sql wrapper.
This is my standard Java method that checks for the presence of a directory.
+public static int isDirectory (String path) {+*
File myFile = new File (path);*
if (myFile.isDirectory()) return SUCCESS; else return FAILURE;*
+}+
I am calling this from my PL/SQL package.
FUNCTION isDirectory (p_path  IN  VARCHAR2) RETURN NUMBER*
AS LANGUAGE JAVA*
NAME 'FileHandler.isDirectory (java.lang.String) return java.lang.int';*
However, the isDirectory always returns false when I try to create a folder in a network drive.
Are there any permissions I should be granting before I can use a network drive ?
Thanks,
Anand

I am able to access that particular folder when I login as the user through which Oracle is run. I believe the user has the permissions on that folder.To so stuff on the OS through java is a risky thing. So the permissions have to be granted explicity, using the DBMS_JAVA.GRANT_PERMISSION() procedure. Something like
call dbms_java.grant_permission('USER621430', 'java.io.FilePermission', 'C:\work',  'read,write');Although you may need execute action to create a folder. Or it may be some other permission entirely. Perhaps, java.lang.RuntimePermission to execute the OS create directory command would be a better approach?
Anyway, [url http://docs.oracle.com/cd/B19306_01/java.102/b14187/chnine.htm#BABHDBCJ]find out more.
