準備文の最後に不要なセミコロンがあるため、削除してください。

この

PreparedStatement pst=con.prepareStatement("INSERT INTO employee_details (E_NAME,E_PASSWORD,E_USERNAME,E_CONTACT," 
       + "E_ROLE) VALUES (?,?,?,?,?)"); 

代わりの

PreparedStatement pst=con.prepareStatement("INSERT INTO employee_details (E_NAME,E_PASSWORD,E_USERNAME,E_CONTACT," 
       + "E_ROLE) VALUES (?,?,?,?,?);");
