jax ws - JAX-WS implementation annotations vs. interface annotnations -

-

i configure jax-ws web service using annotations. use endpoint interface annotated values , used server client, share interface.

my interface looks this:

@webservice(name = constants.name, servicename = constants.service_name, targetnamespace = constants.namespace) @soapbinding public interface imanagementbean {     @webmethod(operationname = "getstatistics")     igetstatsresponse getstatistics(igetstatsrequest request,         @webparam(name = "gridname", header = true, partname = "gridname") string gridname)         throws webserviceexception; }

in corresponding implementation use same annotations, looks quite redundant me.

is there way tell implementation "pull" annotations interface instead of defining them on both sides?

if don't interface, avoid interface.

you can safely start without interfaces , introduce them later need arises. approach fundamentally different in java ee 5. compared java 2 platform, enterprise edition (j2ee) 2003, java ee 6 code simpler, in terms of elimination of several layers, indirections, , abstractions. unlike j2ee, java ee 6 consists of annotated classes without dependencies on platform. approach eliminates need separate business logic infrastructure , makes majority of j2ee patterns , best practices superfluous. in java ee 6, simple cases can solved 2 layers: presentation , business logic.

Perl - how to grep a block of text from a file -

it can in xml or text format. how in general grep block of text in perl? <track type="ws"> <range> <rangestart>0</rangestart> <rangeend>146.912</rangeend> <locationindex>0</locationindex> <propertyindex>0</propertyindex> </range> </track> <track type="ps" id="1"> <range> <rangestart>0</rangestart> <rangeend>146.912</rangeend> <locationindex>1</locationindex> <propertyindex>1</propertyindex> </range> </track> i want grep type="ps" , till </range> . one solution open file, read line line , match block. open(fh, "file.txt"); foreach $line (<fh>) { if ($line =~ m/type="cc"(.*?)<\/range>/) { print $1; } } but there more optimal solution without reading file line l

delphi - How to remove all the grips on a coolbar if I have several coolbands? -

-
Image
if set mycoolbar.fixedorder true,only grip on first band hidden. well,if use delphi 7 create vcl forms application,then put coolbar on , create 3 coolbans hold other controls,only grip , top coolbands can hidden setting mycoolbar.fixedorder:=true. i've uploaded picture make things clear. you got fixedorder property wrong. fixed property not allow bands rearranged if set true . setting property of coolbar true keep user changing bands order @ runtime, user can still move , resize bands. can give advice can do, actual solution problem, well, have wait answer. my advice use 3 coolbars in row , setting "fixedorder" property true , bandborderstyle bsnone . way grip hidden on of them. about property, it's not bug of ide, actual preference of property.

javascript - Animating array of divs; only the final element is modified -

-
this baffling me @ moment. i'm experienced programmer looking throw bit of surprise fiancee on countdown page our wedding. desired effect simulated confetti falling behind main page. setup follows: i have array of divs in javascript. each div absolutely positioned on page. have interval set updates every 50 or milliseconds. on each tick, run loop on array of divs, , calculations , update positions. problem problem having, however, though can see divs created, stored array, , modified (in case, each has slight randomized rotation) during initialization phase, once tick update position starts, div stored in whatever last slot of array gets position updated. tried hard-coding each div index testing purposes, strictly last element update position. upon printing current "left" , "top" style values each div before , after calculations shows value has been changed, no visible change noticeable. here's basic code: javascript var container;
