XP & Java Issue

Nov 20, 2003 10:05PM PST

Good morning,

I'll try to be short and concise. For my job I use some real time fx charts. I've been using them for a year and all of a sudden I can't access them. The tech people at the charts provider tried helping me, but were unable to solve this problem - when I bring up the page, the usual chart window does not open and in I get a red x on the upper left corner of the page (instead of the issual Java coffee cup). Any idea how to solve this problem. THANKS IN ADVANCE FOR ANY TYPE OF HELP!

This is the URL

http://64.94.171.6/Charts/fxcm.html

And this is what I see on the Java console:

User home directory = C:\Documents and Settings\Owner
Proxy Configuration: No proxy

c: clear console window
f: finalize objects on finalization queue
g: garbage collect
h: display this help message

q: hide console
r: reload policy configuration

v: dump thread stack

Their certificate has expired.

Seems something is amiss with that code page since there are priviledge jave calls that require a certificate. The author/maintainer needs to be contacted.

This expired certificate could cause the JVM to just not run said code.

What should I do?

Thanks very much for the response. Why would the application work correctly in the US and not in Spain where I'm currently working?

Thx.

I'm in the US and it didn't work for me either.

Java code with expired certificates is just bad news.

You seem to have not read my response. Which is:

Contact the author and/or maintainer of the application.

I don't see an OS issue.

They lied then

Hi Bob, I did read your response and thank you again for it. I thought I might be able to do something about it from my end (my tech knowledge is limited). They funny thing is that they are able to work with the charts, at least that's what they told me.

Anyway, I'll contact them again.

Have a great weekend.

It didn't work for me. I have the following configuration of XP Pro, IE 6.0 with SUN's JVM and Mozilla with SUN's JVM.

The first error it burped on was the certificate expiration. That can be bad for some JVMs since they could just stop. You may or may not get a message. Since I got such a message, I shared it with you.

So the solutions is?
Nov 21, 2003 1:36AM PST

Thanks for sharing that message, I would've never known bc I did not get myself. My configuration is XP Home with IE 6.0 with SUN's JVM.

What should the administrator do in case they don't know? Just renew their Java certificate?

Thx.

Many companies outsource such a thing and when it breaks, people like you are tossed into the dead end of the pool.

I am not the developer or maintainer of this application. All I can note is what I see from the outside world and as you can tell, my extra nugget of information is that a certificate expired.

Will that fix it?

You'll have to ask them.
