• converting the extracted Java codes into an HTML file;
• transmitting the converted HTML file to the terminal device that made the designation:
• obtaining a modified HTML file from the terminal device that made the designation;
• converting the obtained HTML file into Java codes;
• and
• updating the Java program by replacing the converted Java codes with a part of the Java program related to a structure of a Web page corresponding to the codes, wherein
• in the step of converting into the Java codes, if the obtained HTML file contains a tag indicating a part that cannot be modified, the tag is converted into a Java code indicating a part that cannot be modified, and
• in the step of converting into the HTML file, the code contained in the extracted Java codes is converted into the tag.
