My company has a Juniper netscreen VPN box. It works perfectly with SUN JRE on Fedora-10 and below. It does not work with the OpenJDK that comes with Fedora-11 or any of its updates. I get a dialog box asking about running the appet/trusting the publisher. I answer "yes always trust" for all the dialogs. It starts the applet, but then quits saying "Config failed". I tried F11 with openjdk 22.b16 update. No luck. I would be glad to provide any debugging data.
Everything works. Just tested again with latest updates on i386 platform. Following are the component versions on my working setup: java-1.6.0-openjdk-plugin-1.6.0.0-22.b16.fc11.i586 firefox-3.5-1.fc11.i586 Thanks a *LOT*. I have never before seen OpenJDK/Icedtea plugin work with Juniper SSL/VPN. Now I need to test this in x86-64 mode. For now, you can close this bug.
The original bug was filed with plain vanilla F11 setup with firefox 3.5 beta. The latest updates for openjdk and firefox (and what else, there was too much stuff to keep track of) seem to make it work like a charm.
