Enabling Java in Opera for Linux
These instructions were last updated for Opera 9.1.
Opera uses the Java 2 Runtime Environment (JRE) directly, rather than through the use of a Web browser plug-in. Before proceeding, you may wish to test Java to see if Opera has been able to auto-detect your Java installation using our test applet. If Opera does not show this applet (an animated analog clock), you can try adding the correct Java path for your system in Opera's preferences:
Go to Tools > Preferences > Advanced > Content.
Click the "Java options" button. If this button is dimmed, first check the "Enable Java" option.
Click the "Choose" button for the "Java path" field.
Navigate to the Java directory and click "OK". The path you are looking for is the directory of your Java installation containing the files libjava.so and libawt.so. On the command line, type:
find / -name libjava.so 2> /dev/null
For example, on a Debian system, the path is:
Click the "Validate Java path" button. If you get an error message, try again with a different path.
Click "OK" to save your changes and exit the Java dialog.
Click "OK" to save your changes and exit the Preferences dialog.
