The solution is found,
go to “Configure Build Path”–>”Libraries” tab, click on Add Library, choose “User Library” and click Next, then click “User Libraries” button, then a new dialog will appear. after that, click on “New” button, insert any name, and dont forget to check the “System Library” checkbox. then click OK. after that, click “Add JARs” button to add your required jars.
the new library name will be added to libraries list. when you deploy the project, those jars will not exist in the deployment folder (web-inf/lib)
