If you don't know if you have Java installed, go to http://www.java.com, and you'll know. The same page will offer you to download the latest version of Java, if you don't have one installed, or you have an older version. You can find further instructions for Ubuntu below.

 

Download and unpack the archive you have downloaded from Kenai, enter the SmugLoader-0.5 folder, and launch (by double clicking, or by pressing ENTER, if it's selected) SmugLoaderLauncher.jar. You can also start the application by using SmugLoader-0.5.jar (the application itself), but then you'll not have automatic restart, if you reset/compact the database.

I have to forewarn you that SmugLoader looks right on Sun's Java. OpenJDK seems to have some issues with the UI part.

 

Open up a terminal. First check if you have java installed:

 

 

If you see something like below, you don't have java installed:

Launch the following command from the terminal

 

or open Ubuntu Software Center (the last menu entry in Applications), and search for OpenJDK. Go to OpenJDK Java 6 Runtime, and click the Install button to start the installation. Once the installation completes, check the version again. You'll see something similar to:

Open Synaptic Package Manager, and go to Settings-> Software Sources. Enter the Other Software tab, and check http://archive.canonical.com/ubuntu lucid partner. Close the Software Sources dialog, and click the Reload button.

 

Enter sun-java6-jre in the Quick search text field, and search for it. Right click the sun-java6-jre entry, and Mark for Installation. You'll be offered to also mark other packages. Start the installation, by clicking the Apply button. You'll have to accept the license terms during the installation.

 

If you check for the version, you'll get something similar to this:

Either of the two options you choose, you'll have to use the Terminal, navigate to the application's directory, and launch it from there.
