• Questions every good Java/J2EE Developer should be able to answer?

  - by Rachel

  I was going through Questions every good .Net developer should be able to answer and was highly impressed with the content and approach of this question, and so in the same spirit, I am asking this question for Java/J2EE Developer. What questions do you think should a good Java/J2EE programmer be able to answer? I am marking this question as community wiki as it is not user specific and it aims to serve programming community at large. Looking forward for some amazing responses. EDIT: Please answer questions too, as suggested in the comments, so that people could learn something new regarding the language, too.

• ASP.NET Web Service - Passing a base object with list/collection?

  - by schooner

  We need to create a simple web service in ASP.NET that can be called from PHP or other languages. This in turn will be used to update records in a database for an item submission. The core part is fairly simple, we have a base set of fields for the object - first name, last name, birth date, city, etc. In addition however we need to accept a list of items associated with that object that can range from 0-n. Jan 1 2009, ABC May 1 2010, 123 Jun 30 2010, XXXXX What would be the best way to structure this so it can be easily passed to the ASP.NET web service and processed as a single call for the entire object? Would passing the list of items as a single delimted string be a wise approach? Ex: Jan 1 2009, ABC|May 1 2010, 123|Jun 30 2010, XXXXX

• Can not set Character Encoding using sun-web.xml

  - by stck777

  I am trying to send special characters like spanish chars from my page to a JSP page as a form parameter. When I try get the parameter which I sent, it shows that as "?" (Question mark). After searching on java.net thread I came to know that I should have following entry in my sun-web.xml <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE sun-web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Sun ONE Application Server 8.0 Servlet 2.4//EN" "http://www.sun.com/software/sunone/appserver/dtds/sun-web-app_2_4-0.dtd"> <sun-web-app> <locale-charset-info default-locale="es"> <locale-charset-map locale="es" charset="UTF-8"/> <parameter-encoding default-charset="UTF-8"/> </locale-charset-info> </sun-web-app> But it did not work with this approach still the character goes as "?".

• Any good books out there for advanced concepts like lambdas, delegates, events etc?

  - by they_soft

  I've read about these features but I don't think I've seen enough to consistently apply them in my coding, eg "This would be better done with a delegate than with my other, outdated approach". I know what they do, but I want more examples of use cases, or want some heuristic to help me think in terms of such features. All the books I've seen either focus only on the basics or just mention the features as part of the language. Is there any book out there that deals with this? Preferably C# or language agnostic.

• eclise java internal webbrowser progress listener?

  - by deepthinker121

  Hi All, I need to open an internal web browser from a custom eclipse wizard I have created - and so I am using IWebBrowser webBrowser = browser.createBrowser (IWorkbenchBrowserSupport.LOCATION_BAR | IWorkbenchBrowserSupport.AS_EDITOR | IWorkbenchBrowserSupport.NAVIGATION_BAR | IWorkbenchBrowserSupport.STATUS, null,"TestBrowser", "TestBrowser"); URL url = new URL("http://localhost:8080/app"); webBrowser.openURL(url); Now the problem is - the openURL needs time to complete as it tries to load a page for a webapp and as I am not able to get the progress of the 'load page' operation of the URL - my wizard progressmonitor completes before the URL can be completely loaded . Is there any way to get the status of the page load operation - (to check if its complete or it failed) or add a listener to indicate completion of page load? It is okay for me to use some other implementations of internal web browsers - so please suggest some other approach we cannot add a listener to IWebBrowser.. Thanks for ur help !!

• Proper way to assert type of variable in Python

  - by Morlock

  In using a function, I wish to ensure that the type of the variables are as expected. How to do it right? Here is an example fake function trying to do just this before going on with its role: def my_print(text, begin, end): """Print text in UPPER between 'begin' and 'end' in lower """ for i in (text, begin, end): assert type(i) == type("") out = begin.lower() + text.upper() + end.lower() print out Is this approach valid? Should I use something else than type(i) == type("") ? Should I use try/except instead? Thanks pythoneers

• how to ingore comma when returning json mvc

  - by Darcy

  Hi all, I'm returning JSON from my controller to my view in order to populate a jquery autocomplete textbox in MVC. The problem is, some of my data contains commas, and therefore is split by the autocomplete helper. Heres my code. Controller: public ActionResult GetData() { var data = repository.GetData(); return Json(data); } View (script): $.post("../MyController/GetData", function(data) { var evalData = eval(data) + ""; //formats the text $("#Data").autocomplete(evalData.split(","), { max: 500, matchContains: true }); }); As you can see, I am using the jquery .split helper to split the returned Json. Should I be using regex or should I go with a completely different approach?

• Revision Materals, other than book, for MCTS 70-536 Exam

  - by Damien

  Does anyone have any recommendations on revision materials for the MCTS 70-536 exam other than the monstrosity that is the official book? I am finding it very difficult to absorb the amount of information in the book in such a passive way (i.e just reading) it's not going in. My current approach has been to use the practise tests and make notes on the questions I was unsure about but given the wide varity of questions that could come up I am not sure if this is the correct way to do things. So is there someone with more condensed, bite-size, information to take in. Maybe videos or podcasts? Cheers!

• Multiple records with one request in RESTful system

  - by keithjgrant

  All the examples I've seen regarding a RESTful architecture have dealt with a single record. For example, a GET request to mydomain.com/foo/53 to get foo 53 or a POST to mydomain.com/foo to create a new Foo. But what about multiple records? Being able to request a series of Foos by id or post an array of new Foos generally would be more efficient with a single API request rather than dozens of individual requests. Would you "overload" mydomain.com/foo to handle requests for both a single or multiple records? Or would you add a mydomain.com/foo-multiple to handle plural POSTs and GETs? I'm designing a system that may potentially need to get many records at once (something akin to mydomain.com/foo/53,54,66,86,87) But since I haven't seen any examples of this, I'm wondering if there's something I'm just not getting about a RESTful architecture that makes this approach "wrong".

• Safe deployment of ASP.Net applications

  - by gatapia

  Hi All, I have an asp.net app that I want to deploy safely (with as little down time possible). I would love to do something like blue green deployment but without the need for a second web server. So, I know I can use load balancing, etc but I need a quick and cheap approach. I was thinking of doing something like: Setting up another website (copy of original) in IIS, currently I use host headers to direct traffic across sites). I could then view the new site locally until the site is totally online (due to NHibernate start up and various other high intensity tasks this takes a while). Once site 2 is totally started I would then change host headers around giving me a much much smaller down time. So my question is. Has anyone done anything like this? Will IIS restart my app pool or application when changing host headers (making this useless)? Any other options? Thanks for your help all. Guido

• Using Hive in a maven project

  - by Jason

  I have a project that I am migrating from ant to maven. The project makes use of a lightly-customized Hive build. I figured I would just import this build into our internal maven repo and list it as a dependency in the project's pom file. The problem I'm running into is that the Hive build just generates a bunch of jars in build/dist/lib. Some of these are the core Hive jars themselves and some are jars that Hive depends on. What's the best way to deal with these? Should I put all the core hive jars into our internal repo and just deal with undocumented dependencies in the new project's pom file? Or just jar up everything as a jar of jars and deploy that to the repo? Would that approach even work? Kind of a maven newbie still, thanks for any help.

• How should I use random.jumpahead in Python

  - by Peter Smit

  I have a application that does a certain experiment 1000 times (multi-threaded, so that multiple experiments are done at the same time). Every experiment needs appr. 50.000 random.random() calls. What is the best approach to get this really random. I could copy a random object to every experiment and do than a jumpahead of 50.000 * expid. The documentation suggests that jumpahead(1) already scrambles the state, but is that really true? Or is there another way to do this in 'the best way'? (No, the random numbers are not used for security, but for a metropolis hasting algorithm. The only requirement is that the experiments are independent, not whether the random sequence is somehow predictable or so)

• JavaScript and PHP filename coding conventions

  - by Tower

  Hi, I would like to know the popular ways of naming files in JavaScript and PHP development. I am working on a JS+PHP system, and I do not know how to name my files. Currently I do for JS: framework/ framework/widget/ framework/widget/TextField.js (Framework.widget.TextField()) Framework.js (Framework()) So, my folders are lowercase and objects CamelCase, but what should I do when the folder/namespace requires more than one word? And what about PHP? jQuery seems to follow: jquery.js jquery.ui.js jquery.plugin-name.js so that it is jquery(\.[a-z0-9-])*\.js but ExtJS follows completely different approach. Douglas Crockford only gives us details about his preference for syntax conventions.

• Any ideas on how to implement a 'touchMoveOver' event in Javascript?

  - by gargantaun

  I'm faffing around with SVG, specifically for web content aimed at iPad users. I've created a little dial type thingy that I'm calling a "cheese board" that I'd like to use as an interface element. http://appliedworks.co.uk/files/times/SVGTests/raphael.html Clicking on a piece of cheese (to keep the analogy going) will do "something". That bit's easy. However, I'd like the user to be able to drag their finger around the 'cheese board', firing a new event (touchesMovedOver?) every time they their finger moves over a new piece of cheese. But I can't figure out how to do it since there's no 'mouseOver' equivalent for touch interfaces. If the whole thing was made of squares, I could have created some sort of 'rectContainsPoint' method to be called for every 'touchesMoved', but that approach wouldn't work here. If anyone has any idea about how something like this could be achieved, I'd love to hear it.

• In MVC2, how do I validate fields that aren't in my data model?

  - by Andy Evans

  I am playing with MVC2 in VS 2010 and am really getting to like it. In a sandbox application that I've started from scratch, my database is represented in an ADO.NET entity data model and have done much of the validation for fields in my data model using Scott Guthrie's "buddy class" approach which has worked very well. However, in a user registration form that I have designed and am experimenting with, I'd like to add a 'confirm email address' or a 'confirm password' field. Since these fields obviously wouldn't exist in my data model, how would I validate these fields client side and server side? I would like to implement something like 'Html.ValidationMessageFor', but these fields don't exist in the data model. Any help would be greatly appreciated.

• What are the pros and cons of using an in memory DB rather than a ThreadLocal

  - by Pangea

  We have been using ThreadLocal so far to carry some data so as to not clutter the API. However below are some of issues of using thread local that which I don't like: 1) Over the years the data items being carried in thread local has increased 2) Since we started using threads (for some light weight processing), we have also migrating these data to the threads in the pool and copying them back again I am thinking of using an in memory DB for these (we doesn't want to add this to the API). I wondering if this approach is good. What are the pros and cons? thx in advance.

• Starting a cocos2d game with initial gameplay as background

  - by boz

  Hi All, Id like to start my game, with the initial game play layout as the background, with a buttons layer over the top with maybe 'Tap to start' and a high score etc. and similarly, when the game finishes, id like to just 'pause' the final game play layout and overlay a game over menu of sorts. I tried calling [[CCDirector sharedDirector] pause] as the last line of the appDidFinishLaunching which didnt seem to have any effect. Is there a better way trying to do this? I dont really like my initial approach.

• What next in the career map for a Lead QA Engineer

  - by chandran

  I am a Lead QA Engineer in a Software company and at a stage in my career wherein i need to plan my next move. Option 1: The very obvious move would be to stay as a QA Lead and eventually become a QA Manager. But i don't see very good prospects/future after that. Or am i wrong? Option 2: I love programming/coding, though i haven't spent a whole lot of time on that. So a direct move to becoming a Software Developer is not possible. Will moving to Test Automation eventually lead me to development. Even so, am i looking at step-down in pay and career-level. Option 3: Moving to Product Management. Is this even possible and if so what would be the best approach. Appreciate all your responses in advance. Thanks.

• Rails i18n and routes in javascript

  - by StefanS

  Sometimes it would be really handy to have the Rails localization files available in JavaScript. Same is true for for the routes helpers. I found these two plugins which are exactly doing this: Exposing i18n to JavaScript: http://github.com/fnando/i18n-js Rails Routes in JavaScript: http://tore.darell.no/pages/javascript_routes My questions: Are there any other plugins / gems doing similar things like the two above? What's the right approach in Rails? Meta tag? Additional data- attributes? Thanks for any input!

• LINQ to SQL Web Application Best Practices

  - by derek

  In my experience building web applications, I've always used a n-tier approach. A DAL that gets data from the db and populates the objects, and BLL that gets objects from the DAL and performs any business logic required on them, and the website that gets it's display data from the BLL. I've recently started learning LINQ, and most of the examples show the queries occurring right from the Web Application code-behinds(it's possible that I've only seen overly simplified examples). In the n-tier architectures, this was always seen as a big no-no. I'm a bit unsure of how to architect a new Web Application. I've been using the Server Explorer and dbml designer in VS2008 to create the dbml and object relationships. It seems a little unclear to me if the dbml would be considered the DAL layer, if the website should call methods within a BLL, which then would do the LINQ queries, etc. What are some general architecture best practices, or approaches to creating a Web Application solution using LINQ to SQL?

• How to auto-increment reference number persistently when NSManagedObjects created in core-data.

  - by KayKay

  In my application i am using core-data to store information and saving these data to the server using web-connectivity i have to use MySql. Basically what i want to do is to keep track of number of NSManagedObject already created and Whenever i am adding new NSManagedObject, based on that counting it will assign the class a Int_value which will act as primary_key in MySql. For examaple, there are already 10 NSManagedobjects, and when i will add new one it will assign it "11" as primary_key. these value will have to be increasing because there is no deleting of NSManagedObject. From my approach its about static member in applicationDelegate whose initial value can be any integer but should be incremented by one(like auto-increment) everytime new NSManagedObject is created and also it should be persistent. I am not clear how to do this, please give me suggestions. Thanks in advance.

• Permanent remove of logo in Windows Scripting Host (WSH() scripts.

  - by antonio

  I know two ways to remove the logo permanently. The "official" one: cscript //Nologo //S Will save current command line options for current user. A ftype approach with admin privileges: ftype wsffile="%SystemRoot%\System32\CScript.exe" //nologo "%%1" %%* ftype jsfile="%SystemRoot%\System32\CScript.exe" //nologo "%%1" %%* ftype vbsfile="%SystemRoot%\System32\CScript.exe" //nologo "%%1" %%* Double-%'s are needed only if you use the lines in a batch file. The latter will all users via affect the reg key HKEY_CLASSES_ROOT\<file>\Shell\Open\Command, where <file> can be wsffile, jsfile or vbsfile. Do you know where are stored the cscript //Nologo //S settings?

• Finding the closest grid coordinate to the mouse onclick with javascript/jQuery

  - by Acorn

  What I'm trying to do is make a grid of invisible coordinates on the page equally spaced. I then want a <div> to be placed at whatever grid coordinate is closest to the pointer when onclick is triggered. Here's the rough idea: I have the tracking of the mouse coordinates and the placing of the <div> worked out fine. What I'm stuck with is how to approach the problem of the grid of coordinates. First of all, should I have all my coordinates in an array which I then compare my onclick coordinate to? Or seeing as my grid coordinates follow a rule, could I do something like finding out which coordinate that is a multiple of whatever my spacing is is closest to the onclick coordinate? And then, where do I start with working out which grid point coordinate is closest? What's the best way of going about it? Thanks!

• Implement a vpn

  - by jackson

  I want to build an application client(client.exe) - server to do the following: when the clients run it they are thrown in a VPN and they can communicate each other within 1 applicataion. For example : clients run client.exe and they can see each other in LAN ONLY in Starcraft. From what i have read the right type of vpn for this situation is Secured Socket Tunneling Protocol: "Secure socket tunneling protocol, also referred to as SSTP, is by definition an application-layer protocol. It is designed to employ a synchronous communication in a back and forth motion between two programs. It allows many application endpoints over one network connection, between peer nodes, thereby enabling efficient usage of the communication resources that are available to that network. " Question: I don't have experience with networking programming so my question for the ones who have, is this the right approach? PS1: i don't want something done like OpenVpn, i do this as learning exercise. PS2: the application is targeting Windows and i plan to use .NET Thanks for reading the whole story, i am waiting for your replies.

• Date format strings in .Net and Java

  - by mizipzor

  I have an application that runs on both C# .Net and Java. Two entirely separate but identical code bases. The problem Im having is formatting date and numbers. For example: A user running the .Net variant is inputting a date and a format string. The 26th of April 1986 is formatted 1986-04-26. The actual date, along with the format string, is serialized to an XML file. Later another user running the Java variant opens said XML file and looks at the date. I want them to look the same. Whats the best approach here? There doesnt seem to be a one-to-one mapping between Java and .Nets format strings. Should I limit the possible formats to a selection I know I can represent fully in both .Net and Java?
