Java Problem

[LeMarchand]

Starting to notice that Java isn't working unless from an admin account.

 

If I go to verification page it doesn't do anything on a standard account, but as an admin it works as expected. More to the point, attempting to use any of our LEA sites throws a "no Java client installed" error. Anyone got any ideas?

Latest Java? Which browser(s) are you using? Are they 32-bit or 64-bit?

[LeMarchand]

8.91, both versions, IE11(32 bit).

We had a few website Science Department use which didn't work as Java was out of date but we found that by going to Start, Control Panel, Java, Security and Edit Site List, Add the website and apply it seemed to work.

We did update Java and still didnt work I should add so we did the above

Cheers - the affected LEA site is already in the list (it's fairly regularly updated by script) so it's not that.

Are you using a deployment.config/deployment.properties file to modify various Java settings? If so, could that be causing the issue?

Yes - will take a look tomorrow which changes.

OK. We deploy via msi + mst (I can't remember what it sets - but I tired a manual MST-free installation to no avail) with the following scripted copies:

 

D.Properties

deployment.user.security.exception.sites=C\:\\Windows\\Sun\\Java\\Deployment\\exception.sites
deployment.browser.vm.iexplorer.locked
deployment.browser.vm.iexplorer=true
deployment.browser.vm.mozilla.locked
deployment.browser.vm.mozilla=true
deployment.expiration.check.enabled=false
deployment.security.level=HIGH
deployment.javaws.autodownload=NEVER
deployment.security.validation.ocsp=false
deployment.security.validation.crl=true

D.Config

deployment.system.cachedir = C\:\\WINDOWS\\Sun\\Java\\Cache\\
deployment.system.config = file:\\C:\\WINDOWS\\Sun\\Java\\Deployment\\deployment.properties
deployment.system.config.mandatory = true

+ Java.settings

AUTO_UPDATE=0

 

...and an exception list. Can't see anything that would affect non-Admin users leaping out.

I've taken to not installing Java any more, for minecraftedu I just run it off the network drive, same for pdf split and merge.

@echo off

cd /d P:\minecraftedu\

start \\server.local\share$\Java\minecraftversion\jre1.8.0_51\bin\javaw.exe -jar Launcher.jar

Unfortunately it's needed for various LEA things + who knows what other "vital" software.

[LeMarchand]

Hmmm...

 

Got the Java verification page working, and then the links to the LEA financial system followed suite. Unfortunately it seems that this process needs to be applied at each machine log in. Hoping when the next version of Java pops it will sort itself out. At least there is a work around now.

With regards to Java exceptions, like the above I do this all by script, but change it to a machine setting rather than user. This makes it a lot simpler in terms of deploying exceptions in a domain environment.

That's what I do too. Just can't figure out why this is happening on just one or two machines.

You could try resetting the browser to defaults, in their user context.

Tried that a while back! Beginning to wonder if it's a problem with the financial system. Have just learned that work is scheduled on it over the holidays. Suspecting it was only tested on the council's local connection and not via school access.
