Error File.createTempFile permission to delete has not been granted

Question

Hi,
I am new in Java. I wrote something easy like this:
public class Utils {
public static String createMyTempFile() {
String result = "";
try {
File file = File.createTempFile("test",".txt");
file.deleteOnExit();
catch(Exception e){
result = e.getMessage();
return result;
But appear the next error message:
"Unable to create temporary file"
But i run the same script with SYS user theres no problem, asume is a permission problem, but i dont know which permissions or how can i grant it.
Thank you

Grant Privileges
The relevant permissions must be granted from SYS for JServer to access the file system:
EXEC DBMS_JAVA.grant_permission('SCHEMA-NAME', 'java.io.FilePermission', '<<ALL FILES>>', 'read ,write, execute, delete');
EXEC DBMS_JAVA.grant_permission('SCHEMA-NAME', 'SYS:java.lang.RuntimePermission', 'writeFileDescriptor', '');
EXEC DBMS_JAVA.grant_permission('SCHEMA-NAME', 'SYS:java.lang.RuntimePermission', 'readFileDescriptor', '');
GRANT JAVAUSERPRIV TO SCHEMA-NAME;
The affects of the grant will not be noticed until the grantee reconnects. It is up to the individual to decide on the level of access that is required.
Depending on the documentation used, you may be told to add the directories you intend to access to your UTL_FILE_DIR parameter in the Init.ora file. I have not found this to be necessary when using the Java approach.
