On Ubuntu 11.10 (oneiric), I installed openjdk-7-jre openjdk-7-jdk but could not find icedtea7-plugin. How to get the plugin?

$ java -version
java version "1.7.0_147-icedtea"
OpenJDK Runtime Environment (IcedTea7 2.0) (7~b147-2.0-0ubuntu0.11.10.1)
OpenJDK 64-Bit Server VM (build 21.0-b17, mixed mode)

sudo apt-get install icedtea-web is the correct command.

    I tried the command and was told that I have installed the latest version. But: $ sudo update-java-alternatives -s java-1.7.0-openjdk-amd64 update-alternatives: error: no alternatives for -javaplugin.so. update-java-alternatives: plugin alternative does not exist: /usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/IcedTeaPlugin.so I could not find in the Ubuntu repositories icedtea7-plugin package, only the icedtea6-plugin.

  • If you open firefox and type about:plugins on the address bar icedtea is not listed as the java plugin? Commented Nov 26, 2011 at 0:55
  • Yes, it is listed. Visually it seems that the java plugin running but in version 6. I wish use the version icedtea7. In the Oracle Web site test says I have java 6.23. What to do?

  • I only have openjdk7 installed and the oracle site tells me the same, I would say do not worry about it. Commented Nov 26, 2011 at 2:07
  • your java -version tells your that you are using the version you want, icedtea is running fine, only oracle is reporting it wrong I would say. Commented Nov 26, 2011 at 2:11

its 6 with java 7


Just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the command(s) below:

sudo apt-get install icedtea-7-plugin
  • This solves my problem. It was similar to topic starter's one, but I was to switch java alternatives and it had failed because of missing alternative for that icedtea plugin. Thanks!
