I have a web application (servlet/jsp running under tomcat) which we've put on-line for a limited number of users for testing purposes. I'm now facing the following problem:
We use quite a few small gif files (about 1K) on every page (almost always the same gif files on every page) and quite frequently the user gets broken links to some of these gif files, however when they right-click on the broken link and select Show Image, the image appears. Also if they do a refresh of the page the image typically appears without a problem. I don't see any errors in the tomcat loggings. Any ideas what could be causing this? It is quite annoying for the end-users. Could it have something to do with the network connection?
I have tested it with static html pages and it is also happening on those pages regularly.
Unfortunately I cannot organize the pages into frames, one of the requirements of the application is that there should be no use of frames.
... and the problem is occuring over the LAN. When I execute the application on a local machine (local TOMCAT server, local jsp and gif files, etc), the problem does not occur.
Just to give you some more info, here is the simple static html page I created for testing purpose:
<html>
<head>
</head>
<body>
<img src="/ap21/images/icon_advice.gif">
<br>
<img src="/ap21/images/icon_advisor.gif">
<br>
<img src="/ap21/images/icon_goals.gif">
<br>
<img src="/ap21/images/icon_home.gif">
<br>
<img src="/ap21/images/icon_lifesim.gif">
<br>
<img src="/ap21/images/icon_personal.gif">
<br>
<img src="/ap21/images/icon_report.gif">
<br>
<img src="/ap21/images/icon_risk.gif">
<br>
<img src="/ap21/images/icon_taxes.gif">
</body>
</html>
So, when I load this page with the URL (running on the desapnt01 server under tomcat):
* in most cases all images are displayed correctly,
* however in some cases some images appear as broking links (seems to be more or less random which images)
when I run the same page on my local pc (local tomcat), at the URL * everything works correctly, all images are always shown at any time.
Everytime I get a broken link when testing with the static html page, I see in TOMCAT the following exception appearing:
2003-05-05 09:48:29 - Ctx(/ap21) : Exception in R( /ap21 + /images/icon_goals.gi

I really have no id what is causing this and what I should do to resolve it. Please help me, I'm getting desparate.
PS: I don't know if this could be related to the problem, but the server machine's regional settings are in Spanish.
