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, enterpr

is there easy method swap 2 sublists in list. example: [0 1 2 3 4 5 6 7 8 9 10 11] --> [0 1 8 9 10 4 5 6 7 2 3 11] --> sublist1= [2 3] --> sublist2= [8 9 10] if okay indexes, can done using sublist function multiple files , creating new list object shown below... list<integer> newlist = new arraylist<integer>(mylist.sublist(0, 4)); newlist.addall(mylist.sublist(7, 9)); newlist.addall(mylist.sublist(4, 7)); newlist.addall(mylist.sublist(9, 12)); here swapping index 4 6 indexes 7 8 if want using elements, first use elements find indexes of sublist , use above procedure. don't confused endindex of sublist function... fromindex - low endpoint (inclusive) of sublist toindex - high endpoint (exclusive) of sublist if mention 7,9 in sublist function means elements index 7 till elements below index 9.

i'm trying use notepad++'s find & replace regular expression on following sample: 3 733xxxx (-1) 3 1521xxxx (-1) 3 1521xxxx (-1) how can keep following unmatched? 733xxxx 1521xxxx 1521xxxx i've tried using following expressions: ^(.* \(-1\)).*$ ^(\(-1\))$ the first 1 matches everything, second: nothing. can point me in right direction? there several ways approach this: replace "^ *\d+ +" , " *\(-1\)$" (the quotes clarity) empty string (2 steps) replace "^ *\d+ +(\d+).*$" $1 \d short-hand character class, matches whatever [[:digit:]] matches (numeric digits). (notepad++ uses boost regex). testing, seems it can match unicode numeric digits , don't think going matter in application. the ^ *\d+ + part match text before numbers in middle.  *\(-1\)$ matches spaces , (-1) @ end of line. for ^ *\d+ +(\d+).*$ , regex match whole line, retain part want, numbers in middle.

i have potentially extensive list of json list of objects. i'd load each item individually rather of them in 1 large chunk , display loading icon each item being downloaded. can done jquery .get requests 1 json file? jquery has nothing built in this. you could request data using xmlhttprequest , parse partial data when progress event fired , readystate @ least 3 (loading) rather waiting 4 (done). since involve having incomplete, , therefore invalid, json, have implement custom parser this. need strategy dealing partial pieces of data (such half of object or string). you have either count characters or reparse entire set of data each time readystatechange event fired. it far more trouble worth. you'd better off altering server side logic allow paging of data.

i've written simple code allow bootstrap modals work angular in loads link modal when clicked. links in question have own angular controllers included in source. when modal being loaded first use jquery load it's dependant scripts , have angular compile modal "aware" of it. seems despite fact define controller on-demand modal loaded, angular not "aware" of , throws error (uncaught error: argument 'controllername' not function, got undefined). is there way me tell angular recognize new controller i've added @ run-time? here's modal code i'm using fwiw (prototype code): var directivesmodule = angular.module('modal.directives', []); directivesmodule.directive("modal", function(modalservice) { return function($scope, elem, attrs) { elem.on("click", function(e) { e.preventdefault(); var url = $(this).attr('href'); modalservice.load(ur

major questions currently i'm confused, main questions are: what use of mongoose/mongojs? different if run node.js without mongoose/mongojs? i can't find explanation of big picture of how mongoose or mongojs fits node.js. mongoose's slogan: "elegant mongodb object modeling node.js" not helping. minor questions btw, think mongoose , mongojs doing same type of thing node.js (i.e. interchangeable), this page seems describing mongojs quite differently mongoose: "simple driver emulates mongodb api as possible." might wrong in putting mongoose , mongojs together. if so, please clarify well. maybe shouldn't use mongojs since stackoverflow doesn't have tag it. if so, ignore said above mongojs. while on topic of giving big picture of node.js mongoose , mongojs, else on this page should know? thanks. if you're not using mongodb, database, there no need have type of driver/odm solution. nodejs run fine without the

i analyzing hex data binary data dumps basic command-line program of mine. i'm dumping exact contents of struct (a large array of structs, actually) text file. i create second binary dump, , compare 2 files in vim using xxd create binary-to-text representations of original data. both files exact same size in bytes, , i'm trying compare 2 in meaningful way. small change in data before dump file results in large change in other parts of file, due other sections containing hashes, functions based on value changed, , forth. is possible tell diff or vimdiff say, compare 2 files, , show me parts of file in original file (ie: file 1) value set 1 , , in second file, value set 32 ? thank you! i use: diff <(xxd file1.bin) <(xxd file2.bin) this uses process substitution compare output of 2 xxd processes. note still shows line differences, if byte on line different listed. gives nice hexdump-looking comparison. the classical tool however, cmp . so,

i have checkbox different values. when user change checkbox trigger drupal-function field_attach_update http://api.drupal.org/api/drupal/modules!field!field.attach.inc/function/field_attach_update/7 i know how check checkbox-change jquery how can trigger drupal-function then? you'll want check out form api ajax options . think you'll want define ajax['callback'] function calls field_attach_update. <?php function my_form_func($form, $form_state) { $my_checkbox_val = isset($form_state['values']['my_checkbox']) ? $form_state['values']['my_checkbox'] : null; $form['my_checkbox'] = array( '#type' => 'checkbox', '#title' => t('check me'), '#default_value' => $my_checkbox_val, '#return_value' => $nid, // assuming working node, entity '#ajax' => array( 'callback' => 'my_form_field_update_func',

i have database twitter have users , msgs , users can subscribe , block other users. need show msgs subscribed users not blocked, have query this: select distinct m.mid, m.author, m.content msgs m, subs s, blocks b s.uid = 3 , s.sub_uid = m.author , b.uid = 3 , m.author not in (select b2.bl_uid blocks b2 b2.uid = 3) order m.mid desc limit 30; without 'limit 30' query works fine, gives me correct rows, 'limit 30' have wrong results, because query gives me correct rows plus rows belong users subscribed , blocked. how can 'limit' alter result? edit: user has uid = 3 has 2 users subscribed, users 5 , 6, , user 6 blocked, need show msgs user 5, 'limit 30' msgs user 6 returned. just total guess here, find myself wondering if limit clause being applied subquery well, blocking first 30 authors in blocks table. try refactoring query avoid using subquery. as bonus, you'll eliminate performance problems inherent in subquery implement
