i'm trying develop secure cxf web service java-first approach (java2ws). fine until try define "issuedtoken" policy shown, example, here . the problem is, of course, wsdl generated, can't insert policy in wsdl. tried @policy annotation , managed generate proper wsdl file, find policy ignored service, doesn't show in "online" wsdl. so how go implementing secure web service bottom-up approach? can done? p.s. i'm going deploy service in fuse i think it's not possible way. per ws-thrust note: because ws-issuedtoken support builds on ws-securitypolicy support, available "wsdl first" projects.

i need write function in python, returns valid measurements list of numbers. measure invalid, if closest other measurement less 0.1 second away. also, output list should same length length of input list. thus: [5.1, 5.6, 6.0, 10.34, 10.37, 10.45, 12.5] should return [true, true, true, false, false, false, true] i have approached problem in following fashion: list = [5.1, 5.6, 6.0, 10.34, 10.37, 10.45, 12.5] newlist = [] i, j in zip(list, list[1:]): if j - >= .1: newlist.append(true) else: newlist.append(false) the problem returns following list: [true, true, true, false, false, true] 1 false measurement missing. how can write code differently? your assumption incorrect. there's 2 false measurements. 1 @ 10.37 , 1 @ 10.45. measurement @ 10.34 ok since happens several seconds after previous one. your result has 1 less value input list because you're comparing values 2 2. it's typical "intervals & values...

in mongodb documentation, when search sort, direct me cursor.sort() page . (btw documentation doesn't specify returned out of method.). used in meteor script collection.find().sort('date':1) , got complained find().sort not function. (i thought find() returns cursor, isn't it?) so did further search, , found tutorials tell me use find({}, {sort: ...}). so difference between these 2 methods? in meteor framework, things need meteor way! use collection.find specified in meteor docs , , pass sort specifier . what difference between two? 1 has been wrapped meteor, , works inside framework, other 1 doesn't! i don't believe see performance difference between 'the meteor api' in framework, or 'the standard mongodb api' (non meteor) nodejs.

i saw page . , started wondering how can access visualstategroup of datagrid , or of button code ? you can use getvisualstategroups method of visualstatemanager . if button name of control: ilist list = visualstatemanager.getvisualstategroups(button); if (list.count > 0) { visualstategroup visualstategroup = (visualstategroup)list[0]; foreach (visualstate visualstate in visualstategroup.states) { // put here logic } } indeed list observablecollection , while states freezablecollection . hope can you.

i see there's couchbase.lite-pcl in nuget has been published recently. capable of running in pcl? knows how make work? couldn't find documentation on this. it not official nuget package, milage may vary. it have dll's in portable folder, , dll's added fine pcl , project seems build. try it, might work fine, don't expect direct support couchbase people. alternatively implement interface in pcl, implement per platform methods need official couchbase nuget. inject platform specific implementation @ runtime through ioc container xamarin.forms provide.

i new riakts , trying compare druid riakts in iot area. want checkout efficiency of writes riakts before choosing product.hence, started off below dry-run. data taken: aahrus (data having 4.3 million rows) client used: python node: single independent node. process went smooth. took 6 mins insert 4.3 million rows in batch of 1 million rows. is expected performance or can tweak ? short answer yes, can tweak more performance. first note riak ts, while can run single node, designed clustered. adding nodes , directing writes nodes via load balancer spread workload increase write speed. some other points consider current set increase write speed bit: the python client supports batching writes (not sure if batching using or not). based on experience 100 records per batch seems optimal performance. riak ts replicates data 3 time ha reasons. since using single node replication isn't needed. when create table set n value equal 1. increase write speed. simple exam...

well, working on java project requires input user. realised if user press backspace when there no characters in field, window warning sound heard. how can stop please. system windows 10 if @ behavior may different on different platforms. thank you. behavior may different on different platforms. yes, behaviour can different because controlled laf, should not changing it. but understand how swing works need understand swing uses action provided defaulteditorkit provide editing functions of text components. following code current "delete previous character" action (taken defaulteditkit ): /* * deletes character of content precedes * current caret position. * @see defaulteditorkit#deleteprevcharaction * @see defaulteditorkit#getactions */ static class deleteprevcharaction extends textaction { /** * creates object appropriate identifier. */ deleteprevcharaction() { super(defaulteditorkit.deleteprevcharaction); } /...
