I have created an J2SE application which retrieves data's from mysql via JDBC driver. then I export all of the table data's to DAT file. This project works very well in my development PC which has jre and jdk installed. I need to deploy this application to client pc. I have created a jar file with mysql-connector-java-bin.jar added. When i run this on another machine the dat file is empty. I think as I donot have connection with database on another machine. please enlighten me on this topic as I am very new to deployment.
