i'm developing web application based on jpa + hibernate, spring , wicket. wondering what's best way of implementing transactions in code? transaction manager should use? should org.springframework.orm.jpa.jpatransactionmanager , or org.springframework.jdbc.datasource.datasourcetransactionmanager or else? i'd use spring managing transactions. nanda right , can use jpatransactionmanager. transaction manager abstraction talking here spring's platformtransactionmanager interface, , jpatransactionmanager implementation of interface understands jpa. you should read chapter transaction management spring reference better understand topic.

i have tab-based application windows, developing myself. i add subtle gradient background of tab control. how go around doing this? best method me use? i think implementing custom control takes space of tab control work, how draw gradient using gdi? thanks in advanced. to use gdi you'll need gradientfill function. can use gdi+ gradients. here's plain gdi example: trivertex vert[2] ; gradient_rect grect; vert [0] .x = 0; vert [0] .y = 0; vert [0] .red = 0x0000; vert [0] .green = 0x0000; vert [0] .blue = 0x0000; vert [0] .alpha = 0x0000; vert [1] .x = 100; vert [1] .y = 32; vert [1] .red = 0x0000; vert [1] .green = 0x0000; vert [1] .blue = 0xff00; vert [1] .alpha = 0x0000; grect.upperleft = 0; grect.lowerright = 1; gradientfill(hdc,vert,2,&grect,1,gradient_fill_rect_h); as tab control, sub-class control , override non-client , client drawing handlers render gradient. to sub class control, first create co...

i started think of problem , can't find answer. following code compiles , executes expected object[] test = new string[12]; however, don't know why. i mean, should consider string[] derived class of object[]? think in c#, every array instance of array class. if array generic, should array<t> , , array<string> can assigned array<object> , doesn't make sense. remember interface can use in/out keyword. and in java, i'm not sure, still feel weird. why different types of references can possibly assigned each other when don't have super-sub class relationship? can explain little? thanks lot! it's because reference type arrays support covariance in both java , c#. means every write reference type array has checked @ execution time, make sure don't write wrong type of element :( don't forget both java , c# (and .net in general) started off without generics. if had had generics start with, life have been different. ...

is there anyway can record sound microphone using c# .net what best option if have save audio online in terms of file occupying storage space. any particular format file should saved in optimum output. i think have use either small flash application or silverlight application actual recording. upload file application using web service or similar. and mp3 sort of standard file format sound on web. i'd go that.

this page explains 4 different mono compilers - mcs/gmcs/smcs/dmcs. to me, it's little bit weird have 4 c# compilers. newer version of compiler maintains backward compatibility. i assume that's because of runtime support issues, microsoft's c# has 1 csc.exe supports of runtime versions. it's because mono's compiler written in c# , uses system.reflection, means can access mscorlib runtime it's running on. therefore, example, smcs doesn't target 2.1, uses 2.1 corlib, etc. there have been plan while have *mcs use either mono.cecil or ikvm.reflection instead of system.reflection, mean there single mcs compiler arguments target different runtimes. microsoft's compiler doesn't have limitation because doesn't use .net reflection (it's written in native code).

for reason users produced files end in " @@ " (...)

since $("table").delegate("td", "hover", function(){ $(this).toggleclass("hover"); }); is equivalent following code written using .live(): $("table").each(function(){ $("td", this).live("hover", function(){ $(this).toggleclass("hover"); }); }); according jquery api . i bet i'm wrong isn't same of writing $("table td").live('hover', function() {}); so, what's .delegate() for? .live() listens on document .delegate() listens on more local element, <table> in case. they both act same listening events bubble, 1 .delegate() bubbles less before being caught. your example of: $("table td").live('hover', function() {}); isn't same, again attaches event handler document , not <table> , .delegate() more local elements, more efficient in respects...though still uses .live() under covers. a...

typedef struct { employeet *employees; int nemployees; } *payrollt; typedef struct { string name; } *employeet; i need without accessing array: employeet e = payroll.employees[i]; but gives me error(expected identifier before '(' token) : employeet e = payroll.(*(employee+i)); before struct's interchange employees[i] , *(employee+i) why need avoid array syntax? *(ptr+offset) == ptr[offset] , strictly, every time. you have no performance penalty , array syntax clearer. edit: got real crux of problem. if payroll (in example) pointer type, need use arrow operator instead of dot operator: payroll->employees[0]

can point me in right direction on this? using tools validator wanting execute ajax submit function have if validation passes. have working validation script here works, , ajax call works; i'm having time trying figure out how them work together. how can this? $(document).ready(function() { $("#leadbanker_intake_form").validator({ position: 'center right', offset: [0, 0], message: '<div><em/></div>' }).bind("onsuccess", function(e, els) { // function here still works though forms haven't validated } }); as per the documentation : the second argument jquery object containing fields passed validation. so, in onsuccess callback, need check length of els (the second argument) , make sure it's equal total number of fields you're validating. i think should work (but haven't tested it): $(document).ready(function() { $("#leadbanker_i...

i have seen countless forum posts complaining of issues in gwt when handling dates. still unclear "wrong" date handling, special considerations need made, , when/where/why methods date.setminutes(int minutes) should not used. does have feedback? way in beginning of java (i.e., java 1.0), date/time api largely (solely?) consisted of date class. java folks aware lacked robustness, added calendar class in java 1.1 , tried change date class value object deprecating of it . unfortunately, calendar class wasn't thought-out (see here ) , we're stuck many consider monstrosity. bringing today, gwt supports date because, well... how can live without dates?, doesn't support calendar/gregoriancalendar/timezone because it's ugly , surely there has better answer. sadly, no one's thought of in on 3 years calendar support requested way in january of 2007 , marked planned april 2008. in short, go ahead , use the deprecated date methods in gwt cod...

i know fetching cursor give me access variables %rowcount, %rowtype, %found, %notfound, %isopen ...but wondering if there other reasons use open - fetch - close instructions loop cursor rather than loop cursor cycle... (in opinion better becase simple) what think? from performance standpoint, difference lot more complicated tim hall tip omg ponies linked to imply. believe tip introduction larger section has been excerpted web-- expect tim went on make if not of these points in book. additionally, entire discussion depends on oracle version you're using. believe correct 10.2, 11.1, , 11.2 there differences if start going older releases. the particular example in tip, first of all, rather unrealistic. i've never seen code single-row fetch using explicit cursor rather select into. fact select more efficient of limited practical importance. if we're discussing loops, performance we're interested in how expensive fetch many rows. , that...

i webservice able take username , binary file parameter in same call it. possible? i thought use webclient.credentials , set username way, doesnt seem working the simplest way turn binary data base64 string. string can transmitted passing parameter or inside xml string. web service method: now depending on size files, incur performance loss, not substantial one. to convert byte array base64 string: byte[] data = getsomedata(...);//whatever use byte array. string sdata = system.convert.tobase64string(data ); i choose method on webclient.fileupload() because have more control , more options. rather post page, can send additional information file, usernames, passwords etc. if put them neat xml file. [webmethod] public bool submitfile(string username, string file) { } or [webmethod] public bool submitfile(string data) { } where data be: <data> <authentication> <username></username> <password></password> </a...

i have existing data structure stored xml doc. sitemap. every node has associated metadata (e.g., keywords , description associated node). able use xml_data plugin able load directly source. quick @ both documentation , source, doesn't possible - i'm limited 2 formats described in documentation. however, can't imagine unique use case. seems options extend jstree add own xslt xsl var handle format, preprocess format of file server side result in expected format, or change data interchange format json , convert between json , xml serverside. sense posts have seen is @ least possible serialize/deserialize metadata json_data plugin, i'm not 100% sure on that. can refine direction based on experience? i looks me possible. see: http://www.jstree.com/documentation/xml_data the jstree function called .parse_xml can used convert xml strings or objects dom structure required jstree. edit: wrong! if post example of site map xml i...

the reason why ask i'm telling vendor of ours have use ms antixss library asp.net ui components make, work flex build flash based uis - , wondering if there's equivalent flash (assuming it's vunerable). the short answer is: flash player has lot of features in place prevent xss attacks, they're built in player itself, there isn't particular library need use. if don't call security-related apis, , don't put config files on server, security-wise, using restrictive settings available. (assuming pay attention how make use of user input.) more generally, apis have potential lead xss vulnerabilities rule disabled in xss situations unless actively enable them. example, if html page on site loads in flash file site, , flash content tries to, say, make javascript calls page, calls blocked default unless allow them. similarly, if flash content on site loads in components site, components not able introspect parent unless call apis allow them to. there va...

i realy appreciate spring 3 anoation driven mapping of web controllers i have lot of controllers signatures like: @requestmapping(value = "solicitation/create",method = requestmethod.post) public string handlesubmitform(model model, @modelattribute("solicitation") solicitation solicitation, bindingresult result) but issue is, want write interceptor ho through bindingresults after processing - how them httprequest or httpresponse? as intercpetor methods alike signature public boolean posthandle(httpservletrequest request, httpservletresponse response, object handler) after execution of controller method bindingresult stored model attribute named bindingresult.model_key_prefix + <name of model attribute> , later model attributes merged request attributes. so, before merging can use hurda's own answer, after merging use: request.getattribute(bindingresult.model_key_prefix + "solicitation")

i have java class can extend either of 2 third-party classes, cannot change. can choose either of these implementations @ compile time no changes class other "extends" declaration. unfortunately need choose implementation use @ runtime, not @ compile time. what's best way select between these 2 implementations @ run-time without duplicating entire derived class? it sounds require strategy pattern . the strategy pattern (also known policy pattern) particular software design pattern, whereby algorithms can selected @ runtime. so java class should contain reference 1 of 2 classes want use, , bridge implementation. implementation choose can selected @ runtime. it's not clear problem description, if 2 3rd-party classes implement common interface, java class implement interface , can directly map referenced 3rd-party class.

i want absolute days away datetime today. example, know if date 2 days away, or 78 days away, or 5,239 days away (not likely, idea). using ms sql database returning datetimes time components 00:00:00. date_diff returns relative values have crazy math absolute dates calculating months, years, etc. also, having issues getting date component of today's date in php. edit: mr. w. ended with: $date = $row['airdatedatetime']; $today = date_create(date("y-m-d")); $away = date_diff($today, $date); $d = $away->format("%r%a"); the date_create() part part missing convert actual datetime. also, format needs %r%a . using %r%d works dates in month. the date_diff() function (really, datetime::diff() method) want, , it's not hard. in fact, think example in docs you're after: <?php $datetime1 = new datetime('2009-10-11'); $datetime2 = new datetime('2009-10-13'); $interval = $datetime1-...
