Answer 1

thanks for your reply,
yes i changed the server name and i verified the location of the JDBC driver file(s) on my computer. any way i solved my problem.
you know there was a misunderstanding in what you mean by classpath, i thought that i have to change the classpath from control panel>system>advance>enviroment variable
and then select classpaht and edit it. i was doing this but this is didn't work.
then i don't know why i did that
i went to java program and select my project,right click on it and then select properties>java build path and then select "add external Jars" button and then i simply choose them and add them to my project. and finaly it worked.
thanks alot
