Anyone can help me?

Is there an error in this code?

$.datepicker.setDefaults({
        changeMonth: false,
        stepMonths:1,
        changeYear: true,
    //    showOn: 'both',
        buttonImageOnly: true,
        buttonImage: '<%=request.getContextPath()%>/css/images/cal.gif',
        //buttonImage: '/unes/css/images/cal.gif',
        speed:'fast',
        showStatus: true
    });
    $("#apertureStraordinarie").datepicker({
        showOn: 'both',
