java - CLOB not saving on ORACLE (with JPA, eclipselink) -


i'm working on project in have class attribute:

@column(name="xmldata", columndefinition="clob not null") @lob @basic(fetch=fetchtype.lazy) @getter @setter private string _xmldata;

in database, column type attribute clob.

i'm running application on weblogic 11gr1 (10.3.5), using oracle database (11gr2), jpa , eclipselink jpa provider. problem have everytime save registry on database, clob field not saved.

but if don't put @lob annotation, works fine.

in logs, can see first uses "insert" sentence insert data except clob, , uses "select update" sentence insert clob data, don't know if may part of problem.

thank you.

i've searched lot answer, until realized if using eclipselink, @ least 2.5.2 version, don't have use "@column(name="xmldata", columndefinition="clob not null") @lob @basic(fetch=fetchtype.lazy)". this:

@column(name = "xml_data") private string _xmldata;

eclipselink know how handle clob column.

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; } ...
