<P>PROBLEM TO BE SOLVED: To surely confirm information on versions or correlation of libraries in an archive form and to also confirm identity of each library in an archive form. <P>SOLUTION: A data processing device 10 includes a Jar file decompression part 10A, a change information extraction part 10B, and a difference detection part 10C. The Jar file decompression part 10A decompresses a library in a Jar form of Java (library in an archive form). The change information extraction part 10B extracts information associated with a change of the library in an archive form on the basis of the library decompressed by the Jar file decompression part 10A. The difference detection part 10C detects a difference between a version of the library in an archive form and a version of a library that is a comparison object on the basis of the information associated with the change extracted by the change information extraction part 10B. <P>COPYRIGHT: (C)2012,JPO&INPIT |
