please can someone help? I need to know how can I load this applet into my sim card ?

You can't run SIM applets in Eclipse IDE without using a simulator and you need to use a SIM card simulator (It can be a plugin for your IDE also) or try to run your applet on a real SIM card.

Moreover, for uploading (and installing) your applets, first of all you need to convert that program to a CAP file. There is a tool in Java Card development kit named converter that you can use it to convert applets to CAP files.

Instead of using converter tool directly, you can simply use Eclipse-JCDE plugin to work with this tool and convert your applets.

After converting you need to upload this CAP file on the SIM card. You can use some already-written open source tools to aim this goal. GlobalPlatformPro is well-documented one.

Note that : I'm afraid if the Java Card Development kit is able to convert applets with proprietary SIM APIs to CAP files. but for applets that contains only Java Card API, you can use it simply.
