If you receive the following error when launching the Screaming Frog SEO Spider:

ubuntu java 7 error

This means that although you will have Java 7 installed, it’s not set as your default JRE (Java Runtime Environment). This needs to be changed to run the Screaming Frog SEO Spider.

Open a terminal and issue the following command as suggested in the error message:

sudo update-alternatives –config java

This displays the following in the terminal:

ubuntu terminal

Enter a number to select a version 7 jre (in the case above 0 is a good choice).

Now run the Screaming Frog SEO Spider.

The Screaming Frog SEO Spider makes use of the JavaFX library for all its graphs. This requires java 7 from oracle to be installed. This is an optional step, but required if you would like the spider to display graphs/charts etc.

To do this, open a terminal and type:

sudo add-apt-repository ppa:webupd8team/java

This will ask you for confirmation:

terminal confirmation

Click enter to accept:

enter terminal

Then issue the following:

sudo apt-get update

Waiting for the update to complete, then install oracle java7:

sudo apt-get install oracle-java7-installer

You will now see the following screen:

java 7 installer ubuntu

Click OK, then you will see:

java 7 ubuntu licence terms

Press the left arrow key and hit enter when is highlighted in red as above.

Now check that oracle java7 had been set as your default jre by issuing the following command:

sudo update-alternatives –config java

Which should display:

Java 7 configured baby

If not, select the corresponding number for oracle java 7 and selected enter.

Now re-run the Screaming Frog SEO Spider and you should be able to enjoy the graphs.
