Encountering exceptions when running a java program in the db

Question

hi,
when running the following following program in oracle11g, AIX (5300-07)
DROP JAVA SOURCE DIRLIST;
CREATE OR REPLACE AND RESOLVE JAVA SOURCE NAMED DIRLIST as import java.io.*;
import java.sql.*;
import java.util.Date;
import java.text.SimpleDateFormat;
public class DirList
public static void getList(String directory)
throws SQLException
File path = new File( directory );
String[] list = path.list();
String element;
for(int i = 0; i < list.length; i++)
element = list;
String fpath=directory+"/"+list[i];
File f = new File(fpath);
long len;
Date date;
String ftype;
String sqldate;
SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss:S");
if (f.isFile()) {
len = f.length();
date = new Date(f.lastModified());
sqldate = df.format(date) ;
ftype = "F";
else {
len = 0;
sqldate = null;
ftype = "D";
#sql { INSERT INTO DIR_LIST (FILENAME, filelength, filetype, filemodified)
VALUES (:element, :len, :ftype, to_timestamp(:sqldate,'YYYY-MM-DD HH24:MI:SS:FF3'))
we are encountering the following issues..

Answer 1

If you mean can you run it as a windows 2000 service so the user doesn't see it yes you can.
I recommend the following Java Service wrapper program:
http://www.eworksmart.com/JNT/
It's quite simple to set up and will start when the user logs in (so long as the service is set to start automatically).
Hope that helps,
Seigers.
