[Openjnlp-devel] Works with http proxies through firewall?

From: Hanasaki J. <han...@ha...> - 2002-07-02 17:16:57

Does OpenJNLP work throgh http proxied firewalls?  If so, how is it 
configured?

I have tried the Java Env settings of:
	# JAVA PROXY SETTINGS
	export proxySet=true
	export proxyHost=firewall
	export proxyPort=8080

without success.  These are the right settings for my firewall/proxy.

Thank you,

Unfortunately OpenJNLP has not had any proxy logic added to it. That 
being said, there might be a way to get it to work:

Since OpenJNLP uses the built-in HTTP protocol handler, this should be 
the right approach. There could be issues with the environment variables 
not being picked up, so I'd recommend try setting the proxy values as 
java properties.

You should be able to modify the openjnlp.sh script and add these 
properties by changing the PROPS line:

PROPS="-DproxySet=true -DproxyHost=firewall -DproxyPort=8080"

I have no proxy to test against, but that should actually set the Java 
System properties for proxying every time OpenJNLP starts up.

Note: Unfortunately that won't change the behavior of the launcher, so 
once an app is launched by OpenJNLP I'm afraid the proxy settings will 
not be set for the app.

Modifying the PROPS in the startup script got the proxy config going.

HOwever!  The application will not run.  SwingSet2, from Sun, downloads 
fine.  When it is run, there is a msg that there are no security 
settings.  I clicked "continue" and SwingSet2 did not run.  No error was 
given.  Help!???

Is that the OpenJNLP security warning dialog? That is normal. SwingSet2 
should run fine. (I just tested it on my machine). Do you see any 
messages in the OpenJNLP console window?

One possible reason it might not work is if SwingSet2 tries to retrieve 
network resources. The proxy settings won't be set properly for 
SwingSet2 because it is running in a separate JVM which is not invoked 
using the shell script.

For testing try Cicerone at 
<http://www.puppethead.com/java/apps/Cicerone.jnlp>. It will show you 
what properties are set in the JVM of a launched app. And it's a very 
simple app so if it doesn't work there is something strange going on.

Maybe the OpenJNLP external launcher could be changed to carry forward 
any proxy setting properties. Hmm...

Is this on Mac OS X or Windows?  On Mac OS X just set your proxy 
information in the Network pref panel and the VM will pick them up.
