Jar not found?

Question

Please, help to get the follwing:
The client uses an applet on the Intranet.
In IE everything is ok. But in NS 4.07 (the official browser of the
client) they have problems. From time to time (often) they get an error by the browser.
Question:
Can someone help me to understand this message? What can be the reason of such behaviour?
It is only clear to me that NN can not find the jar archive but why it can not? And what does it mean 'server status 200'
Here the message:
java.io.IOException: server status 200

Answer 1

NN (and IE) often return funny errors when trying to run applets if the disk of the client computer is full.... might be worth checking this?
It's also usually worth clearing out the web & jar caches as this sometimes does the trick
The "server status 200" is almost certainly your web server telling you that it serviced the request correctly... 200 being the code for "success".
