Java problems after firmware v5.3.4 update.

[bigdog]

I was able to upgrade ISY firmware 4.9.x to firmware v5.3.4 with few problems. I am having a Java problem getting it to load on macOS Big Sur.

I have downloaded http://xxx.xxx.xxx.xxx/admin.jsp numerous times after deleting all other instances and clearing all cached files including apps. 

I open http://xxx.xxx.xxx.xxx/admin.jsp and sometimes it will create an icon on my desktop, but usually not. Sometimes the ISY finder shows my ISY 994, other times it shows nothing. 

The big problem is that once I run it the first time and close it, I am unable to open it again. It complains that the jar files were signed with a different cert. So the only way I can run it successfully is to completely turn off caching so that it downloads a new application every time.

It worked okay before the upgrade. I hate Java and avoid it like the clap, but I don't have a lot of choice except to run it from the web. I even stied OpenWebStart and it works better but is old dog slow.

I am sure there must be someone who knows more about Java than I do who might have an idea what I could try. I have seen references here to the "launcher" but I don't know what that is unless that is the ISY Finder (which doesn't seem to work). 

I'm about 95% done with the upgrade but it would be nice to have an icon I can just click on like my other hundreds of programs. Any ideas would be appreciated.

Clear your Jave Cache and applications then use this link for the ISY Launcher

On Big Sur, Admin Console is no longer a separate Window

System Preference | General | Prefer Tabs - set it to "in full screen" (not "always")

 

If you still have problems then try the fix below:

Java applications are blocked by your security settings

• Close all your browsers
• Go to System Preferences | Java to get to Java Control Panel
• Click on Delete Files and make sure you check Applications
• Click on the Settings Button
• Make sure Keep temporary files on my computer is checked
• Click on the Security tab on the top
• Click on Restore Security Prompts and then click on Restore All button on the ensuing dialog
• Click on the Edit Site List
• Click on the Add button
• Enter https://isy.universal-devices.com followed by hitting the Return key on the keyboard. Accept the warning
• Click on the OK button
