PURPOSE: A method for securing a program on a wireless terminal environment is provided to fundamentally prevent a source code of a Java program from being opened by protecting the source of the Java program downloaded from a server on the wireless terminal environment. CONSTITUTION: A jar(Java archive) file secured against execution is downloaded from the server. The execution of the Java program is confirmed. If the execution of the Java program is confirmed, a packet for obtaining an execution-secured file of the jar file is made from a JAD(Java Descriptor) file. The downloaded jar file is updated by receiving the execution-secured file from the server with the packet. The Java program is executed by using the updated jar file.
