Oracle JDK doesn't appear

I had installed originally Oracle JDK 7 update 4, with update-alternatives installation instruction and the JDK became manual mode (3). OpenJDK 7 in auto mode (O).

When I will run/install .jar file Oracle Java Runtime doens't appear. How should I do to fix it?

thank you

  1. If you want to bring Oracle JDK to that menu then you have to create a .desktop file for Oracle JDK under /usr/share/applications if it is not already there. What about clicking Show other application button to see available application? If the Oracle JDK is not there then follow these steps:

    1. sudo gedit to open gedit as super-user
    2. write
      [Desktop Entry]
Name=Oracle JDK
Exec=path to Oracle's java here -jar
Terminal=false
Type=Application
Icon=openjdk-6
MimeType=application/x-java-archive;application/java-archive;application/x-jar;
NoDisplay=true
      then save the file as /usr/share/applications/OracleJDK.desktop
    3. sudo chmod +x /usr/share/applications/OracleJDK.desktop to make the .desktop file executable
    4. sudo gedit /usr/share/applications/bamf.index and add the line OracleJDK.desktop path to Oracle's java here -jar to the end and save.
    5. open the file /usr/share/applications/mimeinfo.cache as super-user(sudo gedit) and add change the line application/java-archive=openjdk-xxx.desktop; to application/java-archive=openjdk-xxx.desktop;OracleJDK.desktop; i.e. just add your newly created desktop entry to mime-cache.
    6. Now you should find Oracle JDK entry under the applications menu if you click view other applications

  2. Samik's answer is great but remove the NoDisplay command which hides the app in Comice OS 4.

    [Desktop Entry]
Name=Oracle JDK
Exec=path to Oracle's java here -jar
Terminal=false
Type=Application
Icon=openjdk-6
MimeType=application/x-java-archive;application/java-archive;application/x-jar;
NoDisplay=false

  3. i have searched the information about this case. Actually Oracle JRE runs automatically when jar files or jar files included are executed. It doesn't support interaction like this.

    if jar files can't be executed, you seems not to be installed correctly.

    Sorry if I'm wrong. That's all i found. If there's someone who know more, please add answer.

  4. The above answer is not sufficient enough

    you also need to update mime list as

    open file in editor

    gedit ~/.local/share/applications/mimeapps.list

    then replace this

    application/x-java-archive=file-roller.desktop;

    to

    application/x-java-archive=OracleJDK.desktop;

    This will resolve the problem.
