xsd - Expected or Recommended usage of the Maven JAXB 2.x Plugin -

-

i'm new xml schema , jaxb , wondering best or expected approach using maven jaxb plugin (http://static.highsource.org/mjiip/maven-jaxb2-plugin/generate-mojo.html)is.

i have simple xml document format i've defined schema. i'm interested in reading compliant xml file java, i'll want add properties pojos won't in xml, used @ runtime.

by default plugin places generated code ${project.build.directory}/generated-sources/xjc. think want copy generated code /src/main/java/whatever , add to/modify code add properties. when change schema, i'd merge changes form newly generated pojos own ones.

the alternative tell plugin place generated source directly /src/main/java , perhaps subclass pojos add own properties, i'm not sure whether marshaling/unmarshaling can still made use extended classes.

anyone have guidance on approach more normal or pitfalls of each are?

in place i'd leave generated sources corresponding jar can built maven without further configuration , put custom code in different project depends on first one. ensures build in right order.

it choice whether derive generated classes or use instances of them in code, attributes or, better, local variables. i'd avoid derivation; after jaxb low level machinery use perform i/o in specific format.

most importantly: forget modifying generated sources; why introduce error prone manual step in development process when can same effect automatically?

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...

android - layout with fragment and framelayout replaced by another fragment and framelayout -

edit: so after comments below, revisted , realized hanging me up. imagine client list , client details activity started : public class clientsmainactivity extends fragmentactivity { @override public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); //studiotabopenhelper db; setcontentview(r.layout.main_client_activity); } } so works great, starts main_client_activity (defined in layout below, , call activity when button on main screen clicked): intent intent = new intent(getactivity(), clientsmainactivity.class); startactivity(intent); easy issue is, clientsmainactivity not call oncreateview or anything, sets layout layout defines fragment, , listfragment. fine cause not trying pass clientsmainactivity , if have hypothetical activity like: sessionmainsactivity called when click on session edit of client, not calling sessionsmainactivity same way (starts activity sets alayout), want layout set defines...
