In windows, when I open a web page containing applet, icon of java plugin console is displayed in systray. But in Ubuntu, I don't find any way to show java plugin console. How can I open java plugin console with FireFox and Chromium in Ubuntu?
It's because the Java Console is hidden by default.
To change this:
First start the Java Control Panel.
From the command line run:
ControlPanel(if not in PATH, you may have to run something like
Or, choose from the Dash like the screenshot below
In the Java Control Panel go to the Advanced Tab, expand Java Console and choose Show Console. Screenshot below:
Now the console will pop up whenever you execute ANY Java Applet.
Fix INFO from this bug.
If you don't have the dash interface (for example if you use Kubuntu, Lubuntu, etc), an alternative method is:
1) Open Terminal and type:
update-alternatives --display java
2) Change Directory to the last directory shown, for example:
- Ubuntu 18.04.5 LTS
- IcedTea Web 1.8
- Steps to enable the IcedTea console:
- Click on the "show applications" icon (bottom left of your screen, by default. The bottom-most item in the launch bar)
- Search for "icedTea" (don't worry about lower/upper case)
- Click on the IcedTea Control Web Control Panel item, probably the only one found (among other things, it looks like a penguin with a giant red nose).
- On the selection list (displayed on the left side), select the option debugging by clicking on it.
- At the debugging settings panel, by the bottom left, there is a drop-down whose label says "Java Console" whose option "Show on startup" is the one you want to select.
- Click "Apply" and "OK". You may now close the IcedTea Control Panel.
The expected behavior is that, when you launch an applet, the console will also keep open, in a separate window, of course, logging stuff with a small delay.
