Today I updated my Java version to 7u51. After the installation, I cleared Java Cache, browser's Cache, and logged into a secure website that uses an Applet to provide certain additional services to the user.
No matter which web browser you use on your computer, you will need the Java plug-in from Oracle in order to view content that uses Java, such as Java applets. Microsoft Internet Explorer is no exception. Java applets are common on the Internet. It is important, therefore, to know how to enable and disable Java in Internet Explorer if it is your web browser of choice.
