How to pull all the txt files from an application server to oracle server

Question

hi
i got some 30 txt files on java application server. i have two questions
1) can java guys will be able to move those files to some oracle directory that will be used by create external table command.
2) can oracle do that using a stored procedure ..but then for it i think i have to create ftppkg and ftpbdy and call and connect each time...
which one is better and why?

Hi,
You can create procedure to move file from application server to oracle server.
Code for list all files in directory
ops$tkyte@8i> GRANT JAVAUSERPRIV to ops$tkyte
  2  /
Grant succeeded.
That grant must be given to the owner of the procedure..  Allows them to read
directories.
ops$tkyte@8i> create global temporary table DIR_LIST
  2  ( filename varchar2(255) )
  3  on commit delete rows
  4  /
Table created.
ops$tkyte@8i> create or replace
  2     and compile java source named "DirList"
  3  as
  4  import java.io.*;
  5  import java.sql.*;
  6 
  7  public class DirList
  8  {
  9  public static void getList(String directory)
10                     throws SQLException
11  {
12      File path = new File( directory );
13      String[] list = path.list();
14      String element;
15 
16      for(int i = 0; i < list.length; i++)
17      {
18          element = list;
19 #sql { INSERT INTO DIR_LIST (FILENAME)
20 VALUES (:element) };
21 }
22 }
23
24 }
25 /
Java created.
ops$tkyte@8i>
ops$tkyte@8i> create or replace
2 procedure get_dir_list( p_directory in varchar2 )
3 as language java
4 name 'DirList.getList( java.lang.String )';
5 /
Procedure created.
ops$tkyte@8i>
ops$tkyte@8i> exec get_dir_list( '/tmp' );
PL/SQL procedure successfully completed.
ops$tkyte@8i> select * from dir_list where rownum < 5;
