[help-GIFT] CSessionManager.cc:1294:throwing AnVENotFound occured: Coul

Date: Tue, 28 Jan 2003 12:26:53 +0800

I got the error when running GIFT. The error is quite similar to this thread [http://mail.gnu.org/archive/html/help-gift/2002-12/msg00007.html].

The log on the screen as follow:

Random number generator has been seeded with 26233
gift: CAlgorithmCollection: The following is the config file
located at "/home/thomas/fusion/img/gift-config.mrml" as read by this program:
<?xml version="1.0" standalone="no"?>
<!DOCTYPE mrml SYSTEM "file:/usr/local/share/mrml.dtd">
<!-- This file has become quite a free interpretation of MRML
    the above !DOCTYPE is rather for the use of psgml than
    a promise that the following is pure MRML. In fact the
    parser does not validate.

This is a configuration file for the server. It contains
information about collections, algorithms and
property sheets.


THIS FILE NEEDS CLEANING. ABOUT HALF OF THE LINES HERE ARE
LEGACY CODE. HOWEVER, IT IS NOT YET TESTED HOW THINGS BEHAVE
WHEN YOU REMOVE THE LEGACY CODE. SO, FOR A WHILE YOU HAVE
TO LIVE WITH QUITE A NUMBER OF OBSOLETE TAGS.

Caught inServer Main:AnGIFTException occured: Could not find Session

I use my own java program to connect the server and sent the "get-server-properties" request to server. Then the error is found and the GIFT server quit to the shell.

Any advice? Thanks a lot.
