java - JAXB basics and parsing xml -


i have understood basics jaxb. tried 1 sample program , need help.

  1. i created sample jaxb project , tried parsing 1 xsd , xml file.. got error. later figured out need jdk targeted run-times jaxb uses files not in jre. can explain more please?

  2. then have parsed files.i haven't worked xml's before not sure syntax followed. think xml file should have mentioning xsd file. correct? parsed in 1 of classes got code generated:

    @xmlaccessortype(xmlaccesstype.field) @xmltype(name = "bookform", proporder = { "author", "title", "genre", "price", "pubdate", "review" })

shouldn't these have datatypes in front of them?

my sample xsd is:

<xsd:schema xmlns:xsd="http://www.w3.org/2001/xmlschema"         targetnamespace="urn:books"         xmlns:bks="urn:books"> <xsd:element name="books" type="bks:booksform"/> <xsd:complextype name="booksform"> <xsd:sequence>   <xsd:element name="book"                type="bks:bookform"                minoccurs="0"                maxoccurs="unbounded"/>   </xsd:sequence> </xsd:complextype> <xsd:complextype name="bookform"> <xsd:sequence>   <xsd:element name="author"   type="xsd:string"/>   <xsd:element name="title"    type="xsd:string"/>   <xsd:element name="genre"    type="xsd:string"/>   <xsd:element name="price"    type="xsd:float" />   <xsd:element name="pub_date" type="xsd:date" />   <xsd:element name="review"   type="xsd:string"/> </xsd:sequence> <xsd:attribute name="id"   type="xsd:string"/> </xsd:complextype>

my sample xml is:

<?xml version="1.0"?> <x:books xmlns:x="urn:books"> <book id="bk001">   <author>writer</author>   <title>the first book</title>   <genre>fiction</genre>   <price>44.95</price>   <pub_date>2000-10-01</pub_date>   <review>an amazing story of nothing.</review> </book></x:books>

where can more info these annotations , how jaxb generates classes?

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
