Wich parameters should be setup to automatic receive proxy settings in v 2.7/2.8 ?
We are using 2.7 and its works very well, but som customer that have a proxy can not upload through the applet. Help is appriciated

Proxy settings are auto-detected by JFileUpload. It is based on Java network configuration. I think you should ask custom to make sure Java network configuration is "Use browser settings". To check it: Start->Control Panel->Java->Network settings->Use browser settings.

What error does your customer get?

As you can see:

[INFO] F - Auto-detect proxy settings : host = null
[INFO] F - Auto-detect proxy settings : port = -1

Proxy is not detected. Did you ask customer to check network settings in Java control panel?

This is mailcorrenspondanse between customer and support. The text is in norwegian/danish,so you may dont understand much off it, but i have attached a couple of screensdumps from user. And you may see something in the log ?

Hej ,,,,,

Det virker som om, at det er helt umuligt at få Java til at benytte proxy ??

Har du nogen ideer?

Hei,

Se pkt 4, proxy settings. Det er anbefalt å bruke ”Browser” settings her. Angående port, så bruker vi helt
alminnelig https webtrafikk, port 443 på serveren, men det er samme port som selve AC systemet
bruker. Deres IT avdeling kan evt se hva som går galt hvis de ser på reglene og loggene i sin proxy. Jeg
mener man bør se på hvilke type data som tillates i denne.

Med Vennlig Hilsen,

Hej Christian!

Som aftalt en kort mail om mine spørgsmål:
Vores netværkstrafik kører næsten uden undtagelse gennem en bluecoat proxy server. (Port 80)...

Det er her jeg forestiller mig det går galt, men hvis jeg skal have åbnet for trafikken, er det nødvedigt at
vide mere om feks. remote adresse og portnumre.

M.v.h. .....

Java Control panel seems fine as Internet Explorer settings. However, proxy seems not auto detected in applet. Which JRE version does he use?

Also, could you try to:
1 - Fill in proxy info in Java control panel and select "Use proxy server". Close all browser windows (to make sure Java is unloaded) and try again.

2 - If it fails then try to pass proxy info in applet parameters with:
<PARAM NAME="param8" VALUE="httpproxyhost">
<PARAM NAME="value8" VALUE="yourproxyhostnamehere">
<PARAM NAME="param9" VALUE="httpproxyport">
<PARAM NAME="value9" VALUE="80">

Hi

We have found the problem. The problem was that we are changing the url to process the file after pageload (with javascript) We have now updateted the js file that loads at page load to include the correct url so now the proxy setup are auto-detected.

Great !
