Abstract

A Java compile-on-demand service system and method for accelerating a processing speed of Java program in a data processing system having a relatively low performance is provided. The Java COD service system compiles a Java class file to be executed in a data processing system into a pattern which can be executed more speedily on the data processing system, and then transmits the compiled result, upon a request of the data processing system connected via a network in order to execute the Java program at a relatively faster speed. The system includes Java program providing servers, data processing systems, and a compile-on-demand server for receiving a service request, downloading a requested Java class file, compiling the downloaded Java class file, and transmitting the compiled result.

Claims

1. A Java compile-on-demand service system for accelerating a processing speed of a Java program in a data processing system, the Java compile-on-demand service system comprising:

a plurality of Java program providing servers for providing at least one Java class file on the Internet;

a plurality of data processing systems which can be accessed on the Internet; and

at least one compile-on-demand server for receiving a service request from the plurality of data processing systems, downloading a requested Java class file from the Java program providing server, compiling the downloaded Java class file into a pattern which can be executed more quickly in the data processing system, and transmitting the compiled result.

2. The Java compile-on-demand service system of claim 1, wherein said compile-on-demand server comprises at least one compiler which compiles a Java class file made of a Java virtual machine language of bytecodes into a native component which can directly executed in a CPU mounted in the data processing system without having a bytecode interpreter or JIT compiler.

3. The Java compile-on-demand service system of claim 1, wherein said compile-on-demand service comprises:

at least one compiler which compiles a Java class file made of a Java virtual machine language of bytecodes into a native component which can directly executed in a CPU mounted in the data processing system without having a bytecode interpreter or JIT compiler;

a database storing the native component compiled by the compiler; and

a compile information table storing a compile name and a compile condition necessary for producing the native component appropriate for the data processing system.

4. The Java compile-on-demand service system of claim 1, wherein said data processing system comprises a native library in which hardware control functions necessary for executing the Java program are implemented, and a native component loader for downloading a native component and relocating the downloaded native component in a memory and executing the same.

5. The Java compile-on-demand service system of claim 1, wherein said data processing system is anyone of a mobile telephone terminal, a PDA, and a set-top-box.

6. A Java compile-on-demand service method for accelerating a processing speed of a Java program in a data processing system, the Java compile-on-demand service method comprising the steps of:

(a) receiving a service request message including information about a location of a Java class file to be compiled into a native component and a kind of the data processing system, from the data processing system mounted with a native component loader for relocating a native library and a native component each made of hardware control functions necessary for executing a Java program in a memory and executing the same;

(b) analyzing the service request message received from the data processing system, downloading a Java class file via the Internet, and compiling the downloaded Java class file into a native component which can be executed in the data processing system having requested the compiling service; and

(c) transmitting the compiled native component to the data processing system and executing the same.

7. The Java compile-on-demand service method of claim 6, further comprising the step of storing the native component produced through step (b) together with the service request message, and transmitting the native component to the data processing system if the same service request message is received from another data processing system.
