input large object from internet

Hi all

According imageviewer example, I made GUI ( by
applet-servlet ) for input data to DB, including blob.
Input data from localhost ( the same PC ) is ok. For
example, I could input image data by writing
"/usr/aji/home.gif" in my GUI.

My question : Is it possible to input blob from other
computer ( from ineternet ) ?
If YES, how to do that ? Which method should I use ?

This is my servlet skeleton code :

.............

String image_file = getImage_file(); // resulting
String "/usr/aji/home.gif"
.......
if(leccod!=null && teacod!=null && date!=null &&
viname!=null && image_file!=null && dept!=null)
{
Statement stat = null;

try
{
LargeObjectManager lom =
((org.postgresql.Connection)con).getLargeObjectAPI();

con.setAutoCommit(false);
byte buf[] = new byte[3000];
FileInputStream fis = new FileInputStream(new
File(image_file));

int oid = lom.create();
LargeObject blob = lom.open(oid);
int s, t=0;

while((s=fis.read(buf,0,buf.length))>0)
{
t += s;
blob.write(buf,0)
}
blob.close();

stat = con.createStatement();
stat.executeUpdate("insert into images values('" +
leccod + "','" + teacod + "','" + date + "','" +
viname + "'," + oid + ",'" + dept + "')");

con.commit();
con.setAutoCommit(false);
..........

Any suugestion would be appreciate.
Thank you.
