Problems upgrading to JRE 1.4.2_06

Question

HI, I'm an application for tradingonline and it requires Java Web Start. Evrything worked well before upgrading with j2re-1_4_2_06-windows-i586-p.exe.
After upgrade my application gets blocked at login phase.
I use Java Web Start 1.4.2_06 (build b03) and in fiel preferences I get problem if under java I flag the runteime environment 1.4.2_06 while everything works correctly flagging only the older 1.3.1_01. I heard the application I use is evolving and in a short time it will loose compatibility with JRE 1.3 so I need to solve this issue. No effective help for the time being from the technical suport of the applciation developers, they don't understand why this happens as it seems I'm the only customer having this problem.
I registered java log activity in a txt file and noticed differences when using JRE 1.3 and trying with 1.4.
Before posting useless information please let me know if you feel there is a way to debug my problem, I will follow the issue trying to give as many infos as possible.
Thanks, bye

Answer 1

HI, thanks for your answer. I have 2 computers attached to a router. Both computers are equipped with kerio personal firewall and the router has a firewall itself. Due to conflict I always keep kerio disabled. To check if the router's firewall is guilty I simply detached a PC from it and connected thorugh ISDN on a stand alone, same problem, on the other computer I disinstalled kerio, cleaned up the registry from all kerio traces and tried again with the same problem, login succesful with 1.3, no way to get in with 1.4.
Here below I paste part of the logs:
first the "succesful" part where I use 1.3.1_01 as you can see from the headings:
Java Web Start 1.4.2_06 Console, started Fri Mar 04 07:39:39 CET 2005

Now the part where I try to get in with 1.4.2_06:
