On every programmable JavaCard there is a pre-loaded applet called "CardManager". This applet has to be used for uploading and installing new applets.

In most cases the used SDK of your JavaCard comes with libraries that encapsulate the necessary steps for selecting the CardManager (including necessary authentication), loading and installing an applet. It bases on the install and load commands defined in the GlobalPlatform standard.

The necessary steps/commands are for example explained here: Installing JavaCard Applet into real SmartCard. However the concrete authentication sequence (CardManager AID, used authentication key) for your card depends on what card type you have.
