Checking Java Virtual Machine
Skip information indexChecking Java on Windows
To carry out the procedures that still require the execution of Java plugins in the AEAT electronic office or to install help programs from previous exercises, it is necessary that Java be installed on the computer.
From the Java website you can install and consult the published information.
Once the installation is complete, you can use the Microsoft Edge browser to carry out the procedures that require Java in the AEAT electronic headquarters. Before you must perform the following configuration:
Go to "Settings" in the browser menu (3-dot icon in the upper right corner).
Select "Default browser" and set "Allow" in the "Allow sites to reload in Internet Explorer mode (IE compatibility)" section.
Next, restart the browser and, in the same "Settings" section, you must now "Add" to the list of sites: https://sede.agenciatributaria.gob.es
Once this is done, Microsoft Edge now works in compatibility mode with Internet Explorer (the icon appears next to the address bar) and should correctly execute the Java plugin in the procedures that require it.
After finishing the corresponding management with Java, it is advisable to run the AEAT page again with Microsoft Edge. To do this, press "Open in Microsoft Edge" when you access the page again. You can also undo the settings made by going back to "Settings", "Default browser".
