I updated ubunut to 15.04 today. Now when I try starting a jar file from the gui it only opens the archive manager.
Checking the open with tab in Properties I can't find Openjdk. I got both Openjdk java 7 and 8 installed according to the software center but despite that they don't show up in the list.
That means that the solution here: How run a .jar file with a double-click? doesn't work for me.

Maybe you don’t have the runtime environment installed!
To install it try the following instructions.
sudo apt-get install openjdk-7-jre
Or you could install Oracle JRE using the PPA method with the following commands.
sudo add-apt-repository ppa:ferramroberto/java
sudo apt-get update
sudo apt-get install sun-java6-jre sun-java6-plugin sun-java6-fonts
Then to use it to open .jar files try the following.
- Right click the .jar file > Properties.
- Click on the “Open With” tab along the top.
- Change the default choice to be the java runtime environment that you have installed.
- Click Close and you should be ready to double click.
You can try the following:
If you have OpenJDK Java 7 Runtime installed in your system, then you should have a file named openjdk-7-java.desktop in the folder /usr/share/applications/
Check if you have the .desktop file.
Go to the terminal and type:
cd /usr/share/applicationsls -l openjdk-7-java.desktopIf the result is:
-rw-r--r-- 1 root root 367 Oct 24 22:29 openjdk-7-java.desktopThen (to associate OpenJDK Java 7 Runtime to the java files) you can edit the file defaults.list also in the folder /usr/share/applications/ .
In the terminal type:
sudo gedit /usr/share/applications/defaults.listSearch for application/x-jar and application/x-java-archive in the defualts.list, and change the .desktop file to the openjdk-7-java.desktop and save the changes.
Now the java files should be open with Open JDK 7 by default. To double-click and run, make sure the file has execute permissions.
You can set the permissions in the terminal with: chmod 755 file.jar or right click in the file, permissions tab and click in "Allow executing file as a program"
Finally double-click in the file to run it.
Hope this will helpful!
Regards.

For some reason the desktop file for OpenJDK is not installed, even though this file is listed.
But you can also use Oracle Java(TM):
Install Oracle Java(TM) with this commands and you have an entry in open with:
To select your default Java, use the following command.
But this has no influence on the menu item "Open with"
