    Why Javascript is called Java (there is no relation between Java and Javascript) why its not called HTMLScript or XMLScript. Any historical reason for this?

  • Static objects and concurrency in a web application

    - by Ionut
    I'm developing small Java Web Applications on Tomcat server and I'm using MySQL as my database. Up until now I was using a connection singleton for accessing the database but I found out that this will ensure just on connection per Application and there will be problems if multiple users want to access the database in the same time. (They all have to make us of that single Connection object). I created a Connection Pool and I hope that this is the correct way of doing things. Furthermore it seems that I developed the bad habit of creating a lot of static object and static methods (mainly because I was under the wrong impression that every static object will be duplicated for every client which accesses my application). Because of this all the Service Classes ( classes used to handle database data) are static and distributed through a ServiceFactory: public class ServiceFactory { private static final String JDBC = "JDBC"; private static String impl; private static AccountService accountService; private static BoardService boardService; public static AccountService getAccountService(){ initConfig(); if (accountService == null){ if (impl.equalsIgnoreCase(JDBC)){ accountService = new JDBCAccountService(); } } return accountService; } public static BoardService getBoardService(){ initConfig(); if (boardService == null){ if (impl.equalsIgnoreCase(JDBC)){ boardService = new JDBCBoardService(); } } return boardService; } private static void initConfig(){ if (StringUtil.isEmpty(impl)){ impl = ConfigUtil.getProperty("service.implementation"); // If the config failed initialize with standard if (StringUtil.isEmpty(impl)){ impl = JDBC; } } } This was the factory class which, as you can see, allows just one Service to exist at any time. Now, is this a bad practice? What happens if let's say 1k users access AccountService simultaneously? I know that all this questions and bad practices come from a bad understanding of the static attribute in a web application and the way the server handles this attributes. Any help on this topic would be more than welcomed. Thank you for your time!

  • Java Champion Stephen Chin on New Features and Functionality in JavaFX

    - by janice.heiss(at)oracle.com
    In an Oracle Technology Network interview, Java Champion Stephen Chin, Chief Agile Methodologist for GXS, and one of the most prolific and innovative JavaFX developers, provides an update on the rapidly developing changes in JavaFX.Chin expressed enthusiasm about recent JavaFX developments:"There is a lot to be excited about -- JavaFX has a new API face. All the JavaFX 2.0 APIs will be exposed via Java classes that will make it much easier to integrate Java server and client code. This also opens up some huge possibilities for JVM language integration with JavaFX." Chin also spoke about developments in Visage, the new language project created to fill the gap left by JavaFX Script:"It's a domain-specific language for writing user interfaces, which addresses the needs of UI developers. Visage takes over where JavaFX Script left off, providing a statically typed, declarative language with lots of features to make UI development a pleasure.""My favorite language features from Visage are the object literal syntax for quickly building scene graphs and the bind keyword for connecting your UI to the backend model. However, the language is built for UI development from the top down, including subtle details like null-safe dereferencing for exception-less code."Read the entire article.

  • Announcing Berkeley DB Java Edition Major Release

    - by Eric Jensen
    Berkeley DB Java Edition 5.0 was just released. There are a number of new features, enhancements, and options in there that our users have been asking for. Chief among them is a new class called DiskOrderedCursor, which greatly increases performance of systems using spinning platter magnetic hard drives. A number of users expressed interest in this feature, including Alex Feinberg of LinkedIn. Berkeley DB Java Edition is part of Project Voldemort, a distributed key/value database used by LinkedIn. There have been many other improvements and optimizations. Concurrency is significantly improved, as is the performance of update and delete operations. New and interesting methods include Environment.preload, which allows multiple databases to be preloaded simultaneously. New Cursor methods enable for more effective searching through the database. We continue to enhance Berkeley DB Java Edition’s High Availability as well. One new feature is the ability to open a replicated node read-only when the master is unavailable. This can allow critical systems to continue offering some functionality, even during a network or master node failure. There’s a lot more in release 5.0. I encourage you to take a look at the extensive changelog yourself. As always, you can download the new release and try it out here: http://www.oracle.com/technetwork/database/berkeleydb/downloads/index.html

  • minecraft wont take keyboard input

    - by Drew S
    After upgrading to 13.10 FTB(minecraft) wont take keyboard input after login in. I can click the buttons but it will not let me type in a address on multiplayer, or copy/paste with mouse.

  • Best dual band A/B/G/N wireless router/ap for Linux

    - by Kevin Bowling
    Hello, I am looking for the best A/B/G/N dual band (simultaneous) router or access point that can be flashed with community firmware like dd-wrt or openwrt. In the past I have used the WRT54G series from Linksys with great success as access points and bridges. The WRT610N looks nice but I'm not sure how well the community firmwares support it. I am open to any manufacturer and any input or experience would be appreciated.

  • Java Desktop Application For Network users

    - by Motasem Abu Aker
    I'm developing a desktop application using Java. My application will run in a network environment where multiple users will access the same database through the application. There will be basic CRUD opreations (Insert, Update, Delete, & select), which means there will be chances of deadlock, or two users trying to update the same record at same time. I'm using the following Java Swing for Clients (MVC). MySQL Server for database (InnODB). Java Web start. Now, MySQL is centralized on the network, and all of the clients connect to it. The Application for ERP Purpose. I searched the internet to find a very good solution to ensure data integrity & to make sure that when updating one record from one client, other clients are aware of it. I read about Socket-server-client & RESTful web services. I don't want to go web application & don't want to use any extra libraries. So how can I handle this scenario: If User A updates a record: Is there a way to update User B's screen with the new value? If user A starts updating a record, how can I prevent other users from attempting to update the same record?

  • Which platform to choose, Java or .NET?

    - by salman
    I am working in a private bank, a leading mid size bank in local market. We are going to create our core banking solution. Existing solution has been developed on Java using IBM Visual Age 4.0. It is very important to discuss architecture first, we have currently more than 350 branches working in standalone mode, and it means they are working in self contained environment. They have their own database server (IBM DB2 9.7) and they are communicating with other branches via sockets to send and receive data. Having experience of .NET for more than 5 years I am trying to convince my superiors to choose .NET platform, but they are reluctant and unwilling. It is my job to encourage them for choosing best available platform to create large scale enterprise application. In simple word, we are going to create a very large scale enterprise financial application, a centralize and integrated which connects all branch networks plus having scalable, solid architecture that easily evolve over time. I want professional people to comment on above scenarios. Which platform to choose .NET or Java? Our all resource is currently working in Java, we have homogeneous environment (no Linux, no Mac and no UNIX). Any idea, any thoughts, any points technical or non-technical i.e. administrative or management point of view will be really appreciated.

  • how to create java zip archives with a max file size limit [closed]

    - by Marci Casvan
    I need to write an algorithm in java (for an android app) to read a folder containing more folders and each of those containing images and audio files so the structure is this: mainDir/subfolders/myFile1.jpg It must be in java, something like perl script is not an option. It would preferably be for the compressed archive in order to squeeze as many files as possible before mailing the zip. Just a normal zip (no jar). My problem is that I need to limit the size of the archive to 16mb and at runtime, create as many archives as needed to contain all my files from my main mainDir folder. I tried several examples from the net, I read the java documentation, but I can't manage to understand and put it all together the way I need it. Has someone done this before or has a link or an example for me? I resolved the reading of the files with a recursive method but I can't write the logic for the zip creation I'm open for suggestions or better, a working example. EDIT: FileNotFoundException (no such file or directory) this was my initial post at Stack Overflow. I've got an answer to it, but I can't set the size of the ZipEntry and the logic doesn't work and also when extracting the my files from the zip I get the compression method not supported error.

  • Microsoft Access 2010: How to Format Forms

    For the purpose of this tutorial, we will be working on formatting a form that people can use to enter in a customer's information. As is, the form is decent and usable, but what if you want to change its look around so that it has a custom look? What if you want to tweak its settings so that it better reflects your company or brand? That is exactly what we are about to do. The process is very simple and can even be a bit fun as you get creative with it. The reasoning behind formatting a form in Microsoft Access 2010 is rather logical. If someone is going to be using a form on a daily bas...

  • Java and what to do with it

    - by SterAllures
    I've been browsing through several websites and several topics on this website. Now I'm just a starting programmer and I want to make a good decision. From what I understand is that Java is used alot for server stuff, and web applets but not really for computer applications running on a client, it's also used for Android programming and several other mobiles. I'm really interested in Android programming, I really love to program for mobile devices, in this case Android because I really think it has a lot of potential and I don't like the iPhone. If I want to program on Android I have to learn Java (aside from Mono). but if my decision changes over the next couple of years I don't think Java is the right language to get a job that programs computer applications. I think I get a job where I have to program server stuff, rather than computer applications. That's why I think C# is a good choice. I can program for Windows Phone 7 (I hope that will get big). and I have the feeling C# is more widely used for computer applications. so I think C# is more versatile looking at Mobile programming and computer programming. Or am I totally wrong thinking this?

  • How to Create Reports in Microsoft Access 2010

    Reports are great ways to present information to parties who want to see relevant data in an organized format that can be easily analyzed. Microsoft Access 2010 allows you to create reports that not only make data more digestible, but also more presentable thanks to their professional look. A report's function comes from its ability to pull in or extract information from single or multiple tables or queries. It could be considered similar to a query in this sense, but what sets it apart is the way in which it presents the information in an easy to use format that you can define to fit your n...

  • Start building websites using Java

    - by Alex coady
    I'm a web developer and I've used PHP, along with MySQL, Javascript, jQuery etc; all of which I'm very confident with and can use on a professional level. What I'm wanting to do however, is to start using Java instead of PHP as I'm creating sites that need to be scalable. I really need a starting point. I can program in Java, I understand the language but have never used it for the web. Links, tutorials, examples would be a great help. I have also considered using Scala (the language Twitter is written in).. but don't really understand the benefits. Please no jargon; I need clear information that essentially takes me through the process of creating a very simple website using Java; I'm more than capable of building the site once that's done.. I think. I've previously used Eclipse so if assume I can. Thanks in advance!
