i invoke jsp parser programmatically. means want able, in java, 'run' jsp page , output, without sending client (i want save output file). don't want 'forward' request jsp page. want able on several jsp pages in row. what best way of doing this? i have found question , balusc doesn't answer question directly. in case wondering, need because want 'precompile' jsps using on other platforms java servlet container. edit what need not .class file, html output. indeed, static once generated have custom jsp tags , want leverage jsp parser expand them. i'm not sure understand point of this. jsps parsed , precompiled .class files. they're java servlets @ point. need servlet engine execute them. if intent capture generated http response "precompiled" response, suggest there's no dynamic content , response same every time send particular request. if that's case, you've got static html. if i'm corre

i've been trying learn spring , hibernate, , i've used lot of examples around net put nice application. however, realized spring supports transaction management. in spring app made whatever calls wanted to, directly hibernate. there reason/benefit why people use spring's transaction management/db stuff? the real advantages are: lightweight declarative syntax. compare: public void saveemployee(employee e) { session s = sf.getcurrentsession(); s.gettransaction().begin(); s.save(e); s.gettransaction().commit(); } and @transactional public void saveemployee(employee e) { sf.getcurrentsession().save(e); } flexible transaction propagation. imagine need execute saveemployee() method part of complex transaction. manual transaction management, need change method since transaction management hard-coded. spring, transaction propagation works smoothly: @transactional public void hireemployee(employee e) { dao.saveemployee(e);

the following sql query displays products sold sorted cost , number of orders have sorted in partitioned manner. namely, products cost of under $100 should go first , else > $100 should follow it. adding having ts.totalsold < 100 query accomplish first partition, filter out other products. operation should atomic, query can executed once. note: cost query has partitioned calculated max of 2 cost columns, makes things bit more complicated (the proposed solutions of case when won't work highestcost not column) select ps.productname, ts.totalsold, ((ps.cost1 + ps.cost2 + abs(ps.cost1-ps.cost2)) / 2) highestcost products ps cross apply (select (select count(orderid) orders os os.productid=ps.productid) totalsold) ts order highestcost asc, ts.totalsold edit : modified query include calculated cost query has partitioned. edited select * ( select ps.productname, ts.totalsold, ((ps.cost1 + ps.cost2 + abs(p

i'm re-writing rails web app in c#. i'm stuck ruby's hash function: # generates 128 character hash def password.hash(password,salt) digest::sha512.hexdigest("#{password}:#{salt}") end the following c# function gives different result: private static string hash(string password, string salt) { return bitconverter.tostring(new sha512cryptoserviceprovider().computehash(encoding.utf8.getbytes(password + ":" + salt))).replace("-", "").tolower(); } what doing wrong? thank you never mind. results are same. if ever need convert ruby's hashing c#, digest::sha512.hexdigest(some_string) does same bitconverter.tostring(new sha512cryptoserviceprovider().computehash(encoding.utf8.getbytes(somestring))).replace("-", "").tolower(); c# lot more verbose, main thing works! :)

as know in windows eol crlf , in linux lf , cr in mac. ( more_info ) i want write program reads linux , mac win files line line in windows. open file use fopen in "rt" mode, don't know how read lines. fgets reads until crlf , lf under windows want work eol=cr files also. so solution? in advance. to open in "t" mode, file must conform platform running on. otherwise have open in binary mode, , sort difference out yourself. the c library helps write program works same on different platforms, not support "cross reading" files.

i'm creating asteroids game , in main class i'm having trouble handling bullets ship fires. all of bullets of "bullet" class , stored in array called "bullets" in main class. when bullets exit screen, removebullet(bulletid) in main class called. private function removebullet(id:int) { removechild(bullets[id]); bullets.splice(id); } in bullet class have enterframe listener traces "stillhere". bullet added main stage using addchild, "stillhere" starts popping in output panel. my problem after call removebullet, "stillhere" keeps popping in output panel, tells me object tried delete still sticking around somewhere in memory. what can rid of completely? because in actionscript have no direct control on when objects removed. the real problem have event listeners still firing. can solve calling removeeventlistener when deleted. however a better approach have 1 enter_frame listener

quick question: what best way implementing line of python code (generates 2 random distinct numbers given range)... random.sample(xrange(10), 2) ...in javascript? thanks in advance! martin here attempt using splice: var = [1,2,3,4,5,6,7,8,9,10];var sample = []; sample.push(a.splice(math.random()*a.length,1)); sample.push(a.splice(math.random()*a.length,1)); wrapped in function: function sample_range(range, n) { var sample = []; for(var i=0; i<n; i++) { sample.push(range.splice(math.random()*range.length,1)); } return sample; } var sample = sample_range([1,2,3,4,5,6,7,8,9,10], 2); we stick function array.prototype have dot notation syntax: array.prototype.sample_range = function(n) { var sample = []; for(var i=0;i<n;i++) { sample.push(this.splice(math.random()*this.length,1)); } return sample; }; var sample = [1,2,3,4,5,6,7,8,9,10].sample_range(2);

we have xcode project first build universal app, , on road changed our mind on having 2 app in same binary, created 2 targets. the first 1 called: appname , iphone: base sdk 4.2 , deployment target 3.1.3. targeted device iphone. the second called: appnamehd , ipad: base sdk 3.2 , targeted device ipad. it's been few weeks building each of platform , able deploy on both ipad , iphone. now ready submit app store , i'm worried potential rejection of code. want submit ipad app now, i've looked around there in itunesconnect site can specify targeted device, , project structured first universal app. i'm wondering how determine on device test binary. more informations architecture: using default generated info.plist file both targets. should have separate info.plist each of target? differences should present between 2 .plist files. here attached actual info.plist file using. thanks in advance. first of all, there's no reason why base sdk ipad tar

i'm working on exiting android code written else , has several memory issues. 1 issue i'm not able understand this. in main activity class has static method called getreference(). method returns reference variable called mthis . now, in oncreate method class myactivity extends activity { private static myactivity mthis; public myactivity getreference(){ return mthis; } public oncreate(bundle savedinstancestate){ mthis = this; } ... } now in content provider or class extending dialog class, uses static method reference context. i'm pretty sure not correct , 1 of reason memory leak. there way current context without passing context object in every class. there application context don't think has method current context. i can remove method , pass reference context object these classes. there other way fix this. i'm pretty sure not correct , 1 of reason memory leak. yes. but there way

i thought overkill unpack entire gem application. there way override single view provides? this gem spree_easy_contact allows add contact form spree application. want tamper 1 of views alternative. if gem namespaced, can namespace view in local application. example, if gem namespaced best_gem_ever, app structure this: app - assets - controllers - helpers - mailers - models - views - - best_gem_ever - - - wonderful_controller - - - - index.html.erb at job, purposefully use technique allow clients overwrite front-end views while still pulling administrative views gem. works well. one caveat, if create asset files store in local assets folder, reason asset pipeline doesn't pick them up. have explicitly added config.assets.precompile list. hope helps!

i need store c# dict can store members based on intptr , enum (castable int if helps). in other words, if same match of intptr , enum (named sp_playlist_type) need able same result out, (that's important). i've figured i'd make struct containing two, , override gethashcode(), i'd need hashing-algorithm doesn't create duplicates 2 numbers, , generates same result every time same 2 numbers present. i think based on way tuple's gethashcode , equality alredy created, have: dictionary<tuple<intptr, yourenum>, yourresulttype> provided on .net 4.0 of course.

i processing large text files (~20mb) containing data delimited line. data entries duplicated , want remove these duplications keep 1 copy. also, make problem more complicated, entries repeated bit of info appended. in case need keep entry containing info , delete older versions. e.g. need go this: bob 123 1db jim 456 3db ax dave 789 1db bob 123 1db jim 456 3db ax dave 789 1db bob 123 1db bits this: jim 456 3db ax dave 789 1db bob 123 1db bits nb. final order doesn't matter. what efficient way this? i can use awk, python or standard linux command line tool. thanks. how following (in python): prev = none line in sorted(open('file')): line = line.strip() if prev not none , not line.startswith(prev): print prev prev = line if prev not none: print prev if find memory usage issue, can sort pre-processing step using unix sort (which disk-based ) , change script doesn't read entire file memory.
