EmpAddServlet is a java file....I m running this on vista...is it due to vista as it doesnt support certain functionalities...This prog is running on xp with access 2003...in the database all the fields are properly named...also i m using access 2010 in vista...is there some modification in 2010 like the 2003 version does not have a username or password....hope 2010 also doesnt require any username or password...

ok...got it...the problem was that emp_id was a primary key in the database...so exception is generated whenever user tries to insert duplicate values....and i was just inserting same test values ...lost 2 days just over this... :(
