• Masters in Computer Science

  - by reko

  Hi, My name is Gautam. I come from India. I am extremely passionate about Web Development.. I like to build web applications all the time.. Can I make this web application building a full time profession? I have just graduated from bachelors... Is there a Master of Computer Science in Web Development? Can I choose Masters in Web Development? Is it a bad choice? Is there a course very close to it Web Development that I can choose? Should I just keep Web Development as a part time thing to do?? Could you please let me know any good universities which offer this course/ close to this course for Spring 2010? Please advice on what I should do because my mind keeps throwing millions of questions on what I should do and my only hope is STACKOVERFLOW helps me as it always does to solve problems..

• Which java technology should i use , if i want to build website with thousands of users

  - by Mirage

  Sorry for asking this question but i searched all java realted question but i got more confused. I am still not clear what should i start with 1)My main is build website in Java because someone told me that there are some machine learning or AI libraries available in java which i can use in java. so i decided to use that as it can reduce my work. Now i don't know java at all some people say following are used to build websites like 1)Servelts alone can build webiste 2)JSP alone can also build webiste 3)Struts 4)Spring with Hibernate 5)SEAM 6)JEE also for webistes Now guys i am confused where should i start from. Where does core JAVA fits in here. i was thinking of perhaps learning python as i know i have to learn Python only not its variations SO please guide me one thing which can solve my basic purpose of using ready made libraries of AI If i can do that with JSP then i will start with that. But i need to learn all of them then its better if can start learning python. I have 5 months to finish webiste. I really don't know why there are many braches of java for doing one thing Please help me.

• How to transform SoapFault to SoapMessage via Interceptor in CXF?

  - by Michal Mech

  I have web-service created and configured via Spring and CXF. See beans below: <?xml version="1.0" encoding="UTF-8"?> <beans <!-- ommited -->> <import resource="classpath:META-INF/cxf/cxf.xml" /> <import resource="classpath:META-INF/cxf/cxf-extension-soap.xml" /> <import resource="classpath:META-INF/cxf/cxf-servlet.xml" /> <bean id="internalActService" class="package.InternalActServiceImpl" /> <jaxws:endpoint implementor="#internalActService" address="/InternalActService"> <jaxws:properties> <entry key="schema-validation-enabled" value="true" /> </jaxws:properties> <jaxws:outFaultInterceptors> <bean class="package.InternalActServiceFaultOutInterceptor" /> </jaxws:outFaultInterceptors> </jaxws:endpoint> </beans> As can you see I added schema validation to my web service. But CXF throws SoapFault when request is not corresponding with schema. I want to send to the client SoapMessage instead of SoapFault, that's why I added outFaultInterceptors. My question is how to transform SoapFault to SoapMessage? I've made few tries but I don't know how to implement outFaultInterceptor.

• Object suddenly missing from HttpServletRequest

  - by Jeune

  I print a list directly in the servlet using the print writer and the list prints. When I try to put in the jsp however the list doesn't print whether I use JSTL or scriptlets. I tried to test in JSTL and scriptlet if the object is null and turns out that it is! Why does this happen and how can I fix this? Servlet code that works for (Artist artist:artists){ resp.getWriter().println(artist.getName()); } Servlet code that puts object in the request public void doGet(HttpServletRequest req, HttpServletResponse resp) throws IOException { ApplicationContext ctx = new ClassPathXmlApplicationContext("com/helloworld/beans/helloworld-context.xml"); ArtistDao artistDao = (ArtistDao) ctx.getBean("artistDao"); List<Artist> artists = null; try { artists = artistDao.getAll(); } catch (SQLException e) { e.printStackTrace(); } req.setAttribute("artists", artists); try { req.getRequestDispatcher("index.jsp").forward(req, resp); } catch (ServletException e) { e.printStackTrace(); } scriptlet code that suddenly finds the object null <% List<Artist> artists = (List<Artist>) request.getAttribute("artists"); if (artists == null) { out.println("artists null"); } else { for (Artist artist: artists){ out.println(artist.getName()); } } %> Even the jstl code seems to agree <c:if test="${artists eq null}"> Artists are null </c:if> <c:forEach var="artist" items="${artists}"> ${artist.name} </c:forEach> For my app I am using weblogic, spring 2.5.6 and ibatis.

• jQuery Address - redirect after form submit

  - by Stian

  Hello all, I use jQuery and AJAX to load content from links and forms into a content div. In addition I use the Address plugin to enable the back button and refresh. On the server side I use Java and Spring MVC. Since I'm using jQuery Address and AJAX the only page that is directly loaded is "index.html". Everything else is loaded into a content div, and what page to load is specified in the hash, ie. "index.html#/users/add.html" will load "users/add.html". Now, "users/add.html" contains a form for creating a new user. When the form is submitted and everything went OK, the controller redirects to "users/index.html". The problem is that jQuery Address doesn't know about the redirect, so the url will remain "index.html#/users/add.html". And this is a problem when you refresh the page and then get sent back to the form, instead of the index page. Is there a way to fix this problem? Thanks, Stian

• N-tier architecture and unit tests (using Java)

  - by Alexandre FILLATRE

  Hi there, I'd like to have your expert explanations about an architectural question. Imagine a Spring MVC webapp, with validation API (JSR 303). So for a request, I have a controller that handles the request, then passes it to the service layer, which passes to the DAO one. Here's my question. At which layer should the validation occur, and how ? My though is that the controller has to handle basic validation (are mandatory fields empty ? Is the field length ok ? etc.). Then the service layer can do some tricker stuff, that involve other objets. The DAO does no validation at all. BUT, if I want to implement some unit testing (i.e. test layers below service, not the controllers), I'll end up with unexpected behavior because some validations should have been done in the Controller layer. As we don't use it for unit testing, there is a problem. What is the best way to deal with this ? I know there is no universal answer, but your personal experience is very welcomed. Thanks a lot. Regards.

• Is there a way to prevent Maven Test from rebuilding the database?

  - by Christopher W. Allen-Poole

  I've recently been asked to, effectively, sell my department on unit testing. I can't tell you how excited this makes me, but I do have one concern. We're using JUnit with Spring and Maven, and this means that each time mvn test is called, it rebuilds the database. Obviously, we can't integrate that with our production server -- it would kill valuable data. How do I prevent the rebuilding without telling maven to skip testing? The best I could figure was to assign the script to operate in a test database (line breaks added for readability): mvn test -Ddbunit.schema=<database>test -Djdbc.url=jdbc:mysql://localhost/<database>test? createDatabaseIfNotExist=true&amp; useUnicode=true&amp;characterEncoding=utf-8 I can't help but think there must be a better way. I'm especially interested in learning if there is an easy way to tell Maven to only run tests on particular classes without building anything else? mvn -Dtest=<test-name> test still rebuilds the database. ======= update ======= Bit of egg on my face here. I didn't realize that I was using the same variable in two places, meaning that the POM was using a "skip.test" variable for both rebuilding the database and for running the tests...

• What java web application framework to use?

  - by frohiky

  One of the main products of my company is an Oracle Forms (and Reports) based application, that "needs" to be re-written in another technology. Why? Users want a more rich interface experience, and we want, preferably, to reduce costs with an open source application server. For this (HUGE) project, we intend to use a java web application framework, keep these points in mind: We have: hundreds of tables on our database (the ORM must be as flexible as possible); some logic which is (and will still be) based on PL/SQL procedures/functions/packages; a lot of CRUDs (the application itself is of an considerable size); a demand to work with/generate documents and workflows; an intranet based user environment; We want: to offer a RIA interface experience; use (if possible) an open source app server; a rapid (as possible) development framework; a somewhat mature framework with a "wise" roadmap (and a considerable community support); a MVC approach combined with JS or GWT widgets (e.g. Vaadin or SmartGWT); Well, in the past weeks I've read a lot of posts, Q&As on stackoverflow, and much more: Wicket, JSF, Tapestry, Grails, GWT, Struts2, Play, Spring, Seam, Echo, .... the list goes on! I've even researched about Alfresco..! The obvious question: Which one to use? At this time, any insight, recommendation, shared experience, advice will be more then welcome!

• Configuring IHS server to direct traffic to the Netty component bound to a port

  - by rbot

  I have a Server Component ( based on Jboss-Netty, which could maintain & handle persistent connections ) deployed in WAS. This component when deployed & initiated within the WAS environment, binds to a port & listens for incoming HTTP connection. [ Why i had to deploy a Netty HTTP Server within WAS is another story - management requirement !! Netty is deployed in WAS as a spring bean which when initiated runs on a port in the machine, independent of WAS ] Clients (mobile app) were able to establish persistent HTTP connections (to the above URL::Port) with this netty component & send/receive requests. Now, I have to replicate this feature in our Production Environment where a IHS Server (Web Server) which sits before the WAS. What i expected is to get a IHS URL which could redirect the incoming packets to the specific PORT on WAS, so that the Client apps can establish a similar persistent http connection. Our Server Admin tried a few combinations and we are not able to identify how to proceed further on this. Your expert ideas would be highly appreciated.

• Grails or Play! for an ex-RoR developer ?

  - by Kedare

  Hello, I plan to begin learning a Java web framework (I love the Java API), I already used Rails and Django. I want something close to Java, but without all the complexity of J2EE. I've found 2 framework that could be good for me : Grails : Grails looks great, it use Groovy that is better than Java for web application (I think..), but it's slower, that use pure-java components (Hibernate, Strut, Spring), it looks pretty simple to deploy (send .war and it's ok !), the GSP is great ! It's a bit harder to debug (need to restart the server at each modification, and the stacktrace is a mix of Java and Groovy stack that is not always understandable..) Play! : This framework also looks great, it's faster than Grails (It's use directly Java), but I don't really like how it use Java, it modify the source code to transform the properties call as setXXX/getXXX, I'm not kind of that... The framework also have caching function that Grails don't (alreary) has. I don't really like the Template Engine. It's also easer to debug (no need to restart the server, and the stacktrace is clear) What do you recommend for ? I am looking for something easy to learn (I used a lot ruby and java, but a little bit java (But I love the Java API)), that is full featured (That's no a problem with all the Java Library availables, but if it's bundle and integrated I prefer), that scale and that is not too slow (faster than ruby), and if possible I would want something with a decent community to easily find support and answer to my questions ;) PS: No JRuby on Rails Thank you !

• Modify Jquery UI slider control

  - by Jean-Yves Deman

  I use the Jquery UI slider control. My slider has a width of 200px. I would like the center of my left handle is shifted 14px to the right and the center of my right handle is offset to the left of 14px. So, my good slider will more than 172px (200-14-14). The background-image measure good 200px. The length of 14px is calculated as follows: width of the handle (28px) / 2. Can you help me solve this mystery? Thank you in advance. .ui-slider .ui-slider-handle { width:28px; height:28px; background:url(images/bulle.png) no-repeat 0 0; overflow: hidden; position:absolute; margin-left:0px; top: -7px; border-style:none; cursor:help; }? I use "margin-left:0px;" to delete the "margin-left:-14px" by default. But, my right handle spring 28px to the right ! Help me please !

• Play framework does not return page and static content

  - by Anton

  I'm using play framework in production for one of my web projects. From time to time Play does not render main page or does not return some of the static content files. I have attached few screenshots below. First screenshot displays firebug console, loading of the site is stucked at the beginning, when serving home page. Second screenshot display fiddler console, when 2 static resources are not loading. This issue is hard to reproduce, it happens 1 of 15 time, I have to delete cache data and reload page. (pressing CRTL-F5 in FF). Issue can be reproduced in most of the browsers. Initially, I was thinging that there is something wrong with hosting provider. But I have changed hosting provided and issue has not gone. Version of the play is 1.2.2. Play is running as standalone server. Not sure, but probably deploying Play to Jetty/Tomcat/Resin would help. Also I'm thinging about rewriting application to another stack (well-known for me - j2ee, spring, whatever) I have no idea how to debug and resolve this issue. Any clue ? Has anyone faced same issue with Play before ?

• Visual Studio identical token highlighting

  - by dsteinweg

  I coded a Mancala game in Java for a college class this past spring, and I used the Eclipse IDE to write it. One of the great (and fairly simple) visual aids in Eclipse is if you select a particular token, say a declared variable, then the IDE will automatically highlight all other references to that token on your screen. Notepad++, my preferred Notepad replacement, also does this. Another neat and similar feature in Eclipse was the vertical "error bar" to the right of your code (not sure what to call it). It display little red boxes for all of the syntax errors in your document, yellow boxes for warnings like "variable declared but not used", and if you select a word, boxes appear in the bar for each occurance of the word in the document. A screenshot of these features in action: After a half hour of searching, I've determined that Visual Studio cannot do this on its own, so my question is: does anyone know of any add-ins for 2005 or 2008 that can provide either one of the aforementioned features? Being able to highlight the current line your cursor is on would be nice too. I believe the add-in ReSharper can do this, but I'd prefer to use a free add-in rather than purchase one.

• What's the best way to learn .NET?

  - by duffymo

  I've been developing Java EE for quite a while now. I've used WebLogic, Tomcat, Spring, and Hibernate extensively, so I have a mental model of what features are available and how things are developed and deployed. The problem that I have with .NET is that I don't have a clear mapping of its features onto Java EE. Here's what I know so far: Java EE - .NET Java - C# JAR - DLL WAR - ? (deployment in general) EAR - ? (deployment in general) Tomcat - IIS web server JSP - ASP? JDBC - ODBC JMS - MSMQ JTA - Microsoft Transaction Manager So much of the functionality that WebLogic handles appears to be dispersed throughout the Windows OS. My confusion kicks in when I see the waves of books at Borders - VB.NET, ASP.NET, C#, etc. If I'm not a VB programmer, would it be possible to stick with C# and write enterprise apps that are the equivalent of what I'm used to with Java EE? If there were a Top Three list of books to learn from, what would they be? The "Head First" series has certainly been successful for Java. http://www.amazon.com/Head-First-C-Brain-Friendly-Guides/dp/0596514824/ref=sr_1_1?ie=UTF8&s=books&qid=1224121193&sr=8-1 Equally well recommended for .NET learning? Thanks. - %

• Database frontend for multiple db engines

  - by xeroxed_yeti

  Hey Stackoverflow, yeah it's spring and a lot of things happens to me... Also changing some software things at my computer, because suddenly everything seems to be boring after starting my laptop. I even changed my wallpaper!!! Besides I'm looking for a new database frontend and after using google with serveral queries I didn't find the right software. You have to know, my laptop and me are very very special :) I'm looking for a database frontend which should have following features can access PostgreSQL and MySQL databases can handle schemata overs a nice sql query tool supports an import and export functionality (something like tab separated text files) it for free looks awesome - every time when a college come to my office he must get the feeling: oh boy, this man really knows his job and should get more money! At the moment I used phpmyadmin, phppgadmin, pgadminIII, mysqladmin and dbVisualizer. Furthermore I was a big fan of the aqua datastudio until it became commercial. This tools offers a great variety of functionalities which can simplify programmes live. However, now you have to buy a license...I'm a scientist and money for software is limited =) So it's my first time (question) here at stackoverflow please be cheerful :)

• When to call Dispose in Entity Framework?

  - by Abdel Olakara

  Hi All, In my application I am making use of Spring.Net for IoC. The service objects are called from the ASP.Net files to perform CRUD operations using these service object. For example, I have CustomerService to do all CRUD operations on Customer table. I use entity framework and the entities are injected .. my question is where do I call the dispose method? As far as I understood from the API documentations, unless I call Dispose() there is no guaranty it will be garbage collected! So where and how do I do it? Example Service Class: public class CustomerService { public ecommEntities entities = {get; set;} public bool AddCustomer(Customer customer) { try { entities.AddToCustomer(customer); entities.SaveChanges(); return true; } catch (Exception e) { log.Error("Error occured during creation of new customer: " + e.Message + e.StackTrace); return false; } } public bool UpdateCustomer(Customer customer) { entities.SaveChanges(); return true; } public bool DeleteCustomer(Customer customer) . . . And I just create an object of CustomerService at the ASP partial class and call the necessary methods. Thanks in advance for the best practice and ideas.. Regards, Abdel Raoof

• Please recommend a CMS framework in Java good for making a monitoring system

  - by TiansHUo

  I already have Java code to display and process data from a database. I would now like to implement the code as modules, and incorporate as a whole into a CMS system. The CMS MUST support Spring, Hibernate, etc. The CMS MUST not be GPL, and preferably open source (lGPL, BSD,etc). The CMS MUST have good documentation and support The CMS MUST be secure (safe from XSS and injection) and support different levels of authorizations, (built-in or module) The CMS MUST have good navigation and tab, (built-in or module) +1, for having a good ajax paginated table module to display data +1, for using ajax to change pages with support for bookmarks and history.back() +1, for using jquery or prototype +1, for being easy to deploy, and easy to add modules +1, for supporting dynamically add/remove and drag-dropping of modules Please recommend a CMS best for the job. Thank you! EDIT: I don't need blogs or wikis or etc. I just want a framework where I can display paginated lists and time series graphs and log files. I will also host some pages for configuration. All of these code are already implemented.

• Help for Platform plus Plugin development by J2ee

  - by echo

  Hi, everybody. I want to develop a monitor platform which can monitor many different subjects such as database, OS, middle ware etc. The system includes two parts: 1. Report center(Show some useful chart and report) 2. Collector(Collect information from monitored subject) For the time being, I just want to monitor some parameters of oracle and Linux. And I will add more monitor subject like MS SqlServer, IBM Db2 ect. later. I need a good architecture so I can easily add new monitor module and not to disturb original framework too much. I want to develop it by the method of “Platform + plugin”. A plugin should have its own UI, setting part and something else. I plan to use struts2 + spring + hibernate to develop report center. I am not very sure how to do design this architecture for I have any “Platform + plugin” experience. I ever googled some information such as OSGI and Portlet. I am not sure which one should be my best choice. Can anyone give me some instruction about it. Your help will be appreciated.

• In Java it seems Public constructors are always a bad coding practice

  - by Adam Gent

  This maybe a controversial question and may not be suited for this forum (so I will not be insulted if you choose to close this question). It seems given the current capabilities of Java there is no reason to make constructors public ... ever. Friendly, private, protected are OK but public no. It seems that its almost always a better idea to provide a public static method for creating objects. Every Java Bean serialization technology (JAXB, Jackson, Spring etc...) can call a protected or private no-arg constructor. My questions are: I have never seen this practice decreed or written down anywhere? Maybe Bloch mentions it but I don't own is book. Is there a use case other than perhaps not being super DRY that I missed? EDIT: I explain why static methods are better. .1. For one you get better type inference. For example See Guava's http://code.google.com/p/guava-libraries/wiki/CollectionUtilitiesExplained .2. As a designer of the class you can later change what is returned with a static method. .3. Dealing with constructor inheritance is painful especially if you have to pre-calculate something.

• Filter large amounts of data in a table w/ jQuery

  - by Bry4n

  I work for a transit agency and I have large amounts of data (mostly times), and I need a way to filter the data using two textboxes (To and From). I found jQuery quick search, but it seems to only work with one textbox. If anyone has any ideas via jQuery or some other client side library, that would be fantastic. Ideal example: To: [Textbox] From:[Textbox] <table> <tr> <td>69th street</td><td>5:00pm</td><td>5:06pm</td><td>5:10pm</td><td>5:20pm</td> </tr> <tr> <td>Millbourne</td><td>5:09pm</td><td>5:15pm</td><td>5:20pm</td><td>5:25pm</td> </tr> <tr> <td>Spring Garden</td><td>6:00pm</td><td>6:15pm</td><td>6:20pm</td><td>6:25pm</td> </tr> </table> So If I start typing in one of the stations in the To: textbox it either displays dynamically like the quick search or i have to press a button (either or) and then in the from: textbox. Lastly it shows me to: station and all its times on the left and the from: station and all its times on the right.

• Array of templated structs

  - by Jakub Mertlik

  I have structs templated by int derived from a Base struct. struct Base { int i; double d; }; template< int N > struct Derv : base { static const int mN = N; }; I need to make an array of Derv< N where N can vary for each struct in that array. I know C/C++ does not allow arrays of objects of different types, but is there a way around this? I was thinking of separating the type information somehow (hints like pointers to Base struct or usage of union spring to my mind, but with all of these I don't know how to store the type information of each array element for usage DURING COMPILE TIME). As you can see, the memory pattern of each Derv< N is the same. I need to access the type of each array element for template specialization later in my code. The general aim of this all is to have a compile-time dispatch mechanism without the need to do a runtime "type switch" somewhere in the code. Thank you.

• How to create an instance of object with RTTI in Delphi 2010?

  - by Paul

  As we all known, when we call a constructor of a class like this: instance := TSomeClass.Create; The Delphi compiler actually do the following things: Call the static NewInstance method to allocate memory and initialize the memory layout. Call the constructor method to perform the initialization of the class Call the AfterConstruction method It's simple and easy to understand. but I'm not very sure how the compiler handle exceptions in the second and the third step. It seems there are no explicit way to create an instance using a RTTI constructor method in D2010. so I wrote a simple function in the Spring Framework for Delphi to reproduce the process of the creation. class function TActivator.CreateInstance(instanceType: TRttiInstanceType; constructorMethod: TRttiMethod; const arguments: array of TValue): TObject; var classType: TClass; begin TArgument.CheckNotNull(instanceType, 'instanceType'); TArgument.CheckNotNull(constructorMethod, 'constructorMethod'); classType := instanceType.MetaclassType; Result := classType.NewInstance; try constructorMethod.Invoke(Result, arguments); except on Exception do begin if Result is TInterfacedObject then begin Dec(TInterfacedObjectHack(Result).FRefCount); end; Result.Free; raise; end; end; try Result.AfterConstruction; except on Exception do begin Result.Free; raise; end; end; end; I feel it maybe not 100% right. so please show me the way. Thanks!

• Creating a Pop animation similar to the presentation of UIAlertView

  I would like to present a view in the same manner as that of UIAlertView - a pop/spring. Unfortunately subclassing UIAlertView is not an option for the view I need to present. I have written some code, but I can't seem to get it as realistic as I would like. I would appreciate any suggestions for greater realism or a link if anything similar has been done (I could not find anything on Google). Thank you. - (id)initWithFrame:(CGRect)frame { if ((self = [super initWithFrame:frame])) { self.backgroundColor = [UIColor whiteColor]; v = [[UIView alloc] initWithFrame:CGRectMake(140, 140, 60, 60)]; v.backgroundColor = [UIColor blueColor]; [self addSubview:v]; [self animate]; } return self; } - (void)animate { [UIView beginAnimations:nil context:NULL]; [UIView setAnimationCurve:UIViewAnimationCurveLinear]; [UIView setAnimationDuration:0.2]; [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(popStep1Complete)]; v.frame = CGRectMake(90, 90, 140, 140); [UIView commitAnimations]; } - (void)popStep1Complete { [UIView beginAnimations:nil context:NULL]; [UIView setAnimationCurve:UIViewAnimationCurveLinear]; [UIView setAnimationDuration:0.15]; [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(popStep2Complete)]; v.frame = CGRectMake(110, 110, 100, 100); [UIView commitAnimations]; } - (void)popStep2Complete { [UIView beginAnimations:nil context:NULL]; [UIView setAnimationCurve:UIViewAnimationCurveLinear]; [UIView setAnimationDuration:0.15]; v.frame = CGRectMake(100, 100, 120, 120); [UIView commitAnimations]; }

• Finding users whose birtday is today with JPA

  - by Jeduan Cornejo

  Hi, I have a table with users and are trying to get a list with the people who have birthday today so the app can send an email. The User is defined as @Entity public class User { @Size(max = 30) @NotNull private String name; [...] @Temporal(TemporalType.DATE) @DateTimeFormat(style = "S-") protected Date birthday; } and I've got a method which returns the people which were born today like so @SuppressWarnings("unchecked") public static List<User> findUsersWithBirthday() { List<User> users = entityManager().createQuery("select u from User u where u.birthday = :date") .setParameter("date", new Date(), TemporalType.DATE) .getResultList(); return users; } This is fine and all for finding people which were born today, however tha's not really that useful, so I've been struggling for a way to find all the users that were born today, independent of the year. Using MySQL there's functions I can use like select month(curdate()) as month, dayofmonth(curdate()) as day However I've been struggling to find a JPA equivalent to that. I'm using Spring 3.0.1 and Hibernate 3.3.2
