Error in Launching Designer

Ignition

I am getting the following exception when trying to launch designer from ignition web page.
I am able to download the “designer.jnlp” file but on launching the following errors are reported :

Exception :

I am using the Mozilla Browser 3.5, basically I am in the same sub net as the machine I am browsing and my browser setting is “No Proxy” . My IP is 172.16.1.31 and IP of Ignition Gateway machine is 172.16.1.72 . Java Network settings in Control Panel>Java are presently in “Use Browser” mode.

Well I have been trying and finally able to get it to work in chrome .

I tried launching the Designer from I.E v8 and had the same error as above with no Proxy set .

I have downloaded Chrome 4.1 and using the same settings i.e “No proxy” I am able to launch the designer finally !!!

I have still not understood why Mozilla and I.E fail to launch the designer . Suspect there is something more than just proxy and network settings .

Go into the “Java” item under the Windows Control Panel and look at the “Network Settings…” window.

What is it set to?

4

The setting in Control Panel>Java Network Settings is “Use Browser” .

5

Interesting - it sounds like those browsers may have a proxy set that you don’t want to use. Try “Direct”

6

I have tried “Direct” with the same error on Mozilla and I.E .

Chrome works fine in both “Use Browser” and “Direct” mode.

This is pretty strange. What version of Java are you running, and what version of Ignition?

8

Java Version 1.6

Observed with :
Ignition Version 7.1.0(b5058)
Ignition Version 7.1.0(b5000)
Ignition Version 7.1.0(b4963)

9

They need to know more than just Java 1.6

It will be something like this:
Sun Microsystems Inc. 1.6.0_19

The _19 is an incremental release and there are/were problems with some.

There is a _20 out and maybe a _21.
