i'm looking way connect 2 or more client sockets directly without need server application running. i've searched several ways , best find jxta p2p protocol. want know if there alternatives other jxta. the basic functionalities of clients interacting (1) ability client send messages other clients , (2) request file available other client has. it's worth noting i'll running multiple instances of application on computer (localhost), having nats or firewalls aren't issues. you want multicast sockets . this question appears have code need implement them. note appropriate applications running on lan, have. supporting multicast across different networks (and across different segments of single large network) requires router support.

suppose have method implemented on server side: @override public user login(string username, string password) throws authenticationfailedexception { // obtain hash user's db entry - omitted simplify code string sessionid = uuid.randomuuid().tostring(); currentlyloggedin.put(sessionid, new session(username)); return new user(sessionid, username); } the method takes username , password, retrieves password database , checks if valid. if valid, returns user object generated sessionid , username. if method fails? or in general, best approach if method not succeed? return null , or throw exception? always return exception. null can mean whatever, exception can have attached message explaining reason of problem. , that's not applicable gwt, java.

i have substitute letter "a" letter "c" in content of txt file. let test.txt txt file. content follows: ace apple i need content in destination folder : cce cpple. is possible in mqfte using ant tasks? the short answer "yes." the longer answer can ant can scripted, including calling other scripts. approach use post-destination call edit file after arrives. call won't fire if file transfer fails. if transfer succeeds post-destination call fire , run task or script edit file. remember if configure run monitor, fire on every file transfer. if want run ad-hoc transfer need submit command line since gui not support pre/post calls.

i need stop process running longer n seconds, here's thought i'd do: |aprocess| aprocess := [ 10000 timesrepeat: [transcript show: 'x'] ] fork. [(delay forseconds: 1) wait. aprocess terminate] fork. i thought proper way proceed, seems fail time time, transcript goes on printing xes. bugs me work , can't figure out work/fail pattern is. this in library, don't need reinvent it.

currently data organised in volume has cache directory (where files first created or transferred). after there suitable directories on volume in subdirs, contain files hardlinked files in cache. done same inode (file) can hardlinked multiple times in multiple directories. now when trying clean volume, recurively go through dirs(not cache) , based on criterion, unlink files (which reduces inode count of cache entry 1). there way me delete cache entry directly, when deleting last hardlink (that bringing down count 2 1). way not have manually parse through whole cache directory clear inodes it, have link count of 1. i have gone through unlink/remove functions, , not find specific of use. there purging algorithm internally takes care of this, can try implement that. any on highly appreciated. in anticipation of prompt reply. no, there isn't want out of box. it might useful deletion when unlinking hardlink , noticing link count 1, since @ point inode should in page ...

simple question... possible use client side mvc 3 validation on inputs of type file? to explain: mvc 3 uses model validation iclientvalidatable , unobtrusive javascript allow write validation on server side , have render client side using jquery validate using microsoft's plugins. make property required add attribute below [required] public httppostedfilebase cvfile {get; set;} as long client side val , unobtrusive javascript on in config should fire on client. however httppostedfilebase (i.e. <input type="file" name="model.cvfile" />) not run required on client side. any ideas how can achieved keeping relationship server side validation simple answer: httppostedfilebase renders "file" input type security issue and, afaik, not scriptable. there's no support "out of box". edit: seems popular topic online. http://www.hanselman.com/blog/abacktobasicscasestudyimplementinghttpfileuploadwithaspnetmvcincludingte...

i have implemented simple dijkstra's algorithm finding shortest path on .osm map java. the pathfinding in graph created .osm file works pretty well. in case user's current location and/or destination not node of graph (just raw coordinates) how 'link' coordinates graph make pathfinding work? the simple straightforward solution "find nearest current location node , draw straight line" doesn't seem realistic. if have situation on attached picture? (upd) the problem here before start 'smart' pathfinding algorithms (like dijkstra's) 'link' current position graph, dumb formula (a hypotenuse pythagorean theorem) of finding nearest node in terms of geographical coordinates , formula not 'pathinding' - can not take obstacles , types of nodes account. to paraphrase - how find shortest path between , b if b node in graph, , not node? have heard of other solutions problem? the process you're describing " ma...

i'm new functional programming. have basic question. i'm using hugs interpreter, i write function in haskell; went though several tutorials, i'm not getting it. fact :: int -> int fact n = if n == 0 1 else n * fact (n-1) this gives me syntax error :-s error - syntax error in input (unexpected `=') i assume type right interactive prompt. sadly, these relatively primitive in haskell - complex definitions, such fact , can't entered @ prompt, @ least not in same way you'd write them. you need put function definitions etc. modules, load via (e.g.) :load fact.hs . there resources hugs provide more information on , other topic (i used http://cvs.haskell.org/hugs/pages/hugsman/index.html check assumptions). also note indentation matters, code won't work way posted here when in module. tutorials have correct versions. if not, they're useless , should forget them.
