 First of all select "sqljdbc4.jar" file, right click it and select "Extract to sqljdbc4\"

Inside 'sqljdbc4' folder you will find three files. Go inside 'Meta-inf' folder.

Delete all files and folder except 'MANIFEST.MF'

Open  'MANIFEST.MF' file and remove all lines except first line.

Save the file and compress folder 'com', 'META-INF', and 'microsoft'.

Finally, change the name of compressed folder into 'sqljdbc4.jar'. Import this jar file to your project library.
