  • Where to start when digging into an existing J2EE codebase?

    - by Jacob Krustchinsky
    I work for a company that produces enterprise applications to be used by schools and districts to manage all of their tests and standards data. Their existing application is written in J2EE and is very large. I personally am a seasoned PHP and Ruby = RoR developer and I have been asked to attempt to implement easily added but crucial features to an existing J2EE codebase. I am very familiar with Java SE and know the architecture of a web application well. What I am asking for is, will this suffice for the task ahead and what tips can you give me in digging into the code base and actually efficiently adding these new features? Is there anything important I need to know before beginning and what can I expect in terms of problems and issues coming from a Java SE, PHP, RoR background? Time isn't too much of an issue, I should have plenty of time to familiarize myself with J2EE.Please also note, syntax will not be a problem here.

  • Top X tips to code & debug efficiently [closed]

    - by user1510230
    I'm starting a big Java project and I wanted to have some advices that could benefit us all. What are the X (X could be 5 / 10 / ... or even 100 :) most important tips to code and debug efficiently in general (and in particular with java / javascript) ? I'll start with some basic ones : Use functions everytime a portion of code is used more than twice. Try not to code features with more than 15 lines of code in one shot. Rather write 5 lines of code then check if they work correctly then write 5 more... and so on start with the outcome of the function and then code it backwards (bottom-top approach) ... Thanks everybody

  • Parallel Threading in Multi-Language Software?

    - by Smarty Twiti
    I'm developing a software that contain many modules/Daemon running in parallel manner, what i'm looking for is how to implement that, i cannot use Thread because some of those modules/Daemon are perhaps implemented in other languages (C,java,C#...). For example I'm using C for Hooking Messages exchanged between Windows kernel and top level applications, Java/C# to use some free library to simply parse XML(for example) or to accept and execute commands over the network..this can be done by C Language but just to improve productivity... Finally for GUI I'm using Ultimate++ (c++) that is like the main process that call and monitor(activate/deactivate/get state) of all other modules/Daemon through an interface. I admit that the development of each module/Daemon in a separate language greatly facilitates maintenance, but especially I am obliged to do that.. What is the best practice way to do that ? All helps will be appreciated.

  • Inverted Cursor with ARM OpenJDK 7 in Chromium, and clicking issues?

    - by Espionage724
    So I have a strange issue. When using Chromium on the Nexus 7 port of Ubuntu, Java apps in the browser have the cursor flipped, literally (not just inverted movement, but the cursor itself flipped too). Also, clicking in java apps, both in the web browser and standalone, clicks don't register when using a USB mouse. I have to tap the screen itself to click. And another issue with the mouse; it seems Minecraft is unable to run, and freezes with an error similar to being unable to "GetInput", possibly related to the clicking issue above.

  • My Future as a Developer

    - by jmquigley
    You have been a developer for 16 years, mostly in the unix environment woring with C, C++ and Java. You are proficient in those skills, but can always improve. The jobs for C and C++ developers working in the Unix environment are not as plentiful as they used to be, so you're looking to expand your skills. If you were going to focus on an area of technology for the next 10 years, and you had a choice of C# or to continue with your work in Java and expand those skills, which would you choose and why? I love being a programmer. I want to focus on an area that would put me in demand so that I can continue to be a programmer. This is not meant to be subjective, I'm looking for guidance and advice from other professionals. This is a question that is at the front of my mind right now. TIA.

  • System.getProperty("user.dir") cannot get my project root path ,but the path which my eclipse is located

    - by facebook-100005613813158
    As the title goes , I have class named GetException.java,inside it ,I read a xml file in a static code block like(Because this document is shared): static{ ... document = db.parse(new File(System.getProperty("user.dir")+"/src/exception/ExceptionCode.xml")); ... } To test if the file path is correct, I write a main function just inside GetException.java, it proves that the path is correct ,xml file can be read successfully. My project root dir is "/home/wuchang/workspace/MongodbI". But When this Class is loaded from other class,such as I called one of its static functions , it reports the error message: /home/mrs/??/eclipse/src/exception/ExceptionCode.xml (No such file or directory) /home/mrs/??/eclipse/ is actually my eclipse installation directory.So , I wander how System.getProperty("user.dir") returned the eclipse installation directory to me ,instead of my project root directory?

    - by Bluechip Solutions
    I am a student at Middlesex Universtity, London studying Information Technology. I really love software development and I have taught myself how to write HTML + CSS, JavaScript (I use jQuery and AngularJS) and Java (I learnt this in school). I have developed few apps (a desktop app in Java and a mobile app with AngularJS and PhoneGap) I am looking at applying for a part-time programming job to develop myself. Are there part time jobs available for someone like me and are my skill set enough to get me a job? I understand this topic may not be ideal here but this is the only place I know can provide me answers. Thank you!

  • What book do you recommend for the OCAJP certification (1Z0-803) and OCPJP (1Z0-804) [on hold]

    - by Muhammad Gelbana
    I find completely contradicting reviews for the VERY same book on amazon and even some book writers are rewarding people for good reviews so basically most of the reviews are totally fake ! You can even figure it out from the reviewer name, which you'll similar to the writer's name and assume that they could actually be from the same country and the reviewer is just being helpful, to the book writer of course ! I can't make my mind for which book I should buy ! I only need a book or two that covers the Java associate and professional topics very well, not just an overview, I need a material that covers everything from A to Z. Even though I've been developing in Java for around 4.5 years but I must not know a detail or two. Would someone kindly shed some light on a good book based on actual experience with the book ? THANK YOU !

  • Either I'm not confident I just don't know anything [on hold]

    - by zoomerzoom25
    My name is Sael and I'm 14 years old. Since I was 12 and I got my first computer I instantly go interested in making games. So of course like any other I googled it, got discouraged and forgot about it for a few months. When I was 13 I decided to continue programming, and decided that java would best suit me. Now after a year, I have a basic understanding of java and how it works (it just clicked instantly one day). Anyways, my problem is that I know how I'm going to make a simple game in my head, but as soon as I click that "New Project" button on eclipse, I'm instantly lost and can't figure out where to start. I can't do much without a tutorial beside me since my mind is so dependent on it. So here's the question : what can I do to get past this problem of mine, and have any of you felt like this before? sorry if my English is a bit incorrect, Spanish is my main language* I've made Minecraft mods before

  • Question about main(String[] args) [migrated]

    - by Andrew0085
    I'm new to programming, and I'm using java. Here's a program I wrote: class HelloApp { static String hi; public static void main(String[] args) { int length = args.length; if (length > 0) { hi = args[0]; sayHi(); } } static void sayHi() { if (hi == "hello") { System.out.println("Hello!"); } } } My question is: Why doesn't inputting "java HelloApp hello" make "Hello!" appear on the next line?

  • How to distribute java components for developers to use?

    - by coder
    I am not sure how to put the correct title. but here is the brief explanation. With Microsoft .NET, i created a server side custom control using C# to be used in ASP.NET pages. I distribute the DLL generated as a component. developers will include that and use in their ASP.NET project. Likewise, how can i do for Java based web components for to use with JSP or JSF or any other java web frameworks?

  • How to pass a serialized object to appengine java task?

    - by aloo
    Hi all, I'm using java appengine and the task queue API to run async tasks. I would like to add a task to the task queue but pass a a java object as a parameter. I notic the task options api can add a parameter as a byte[] but I'm unsure how to use it. 1) How would I serialize my object to a byte[]? and 2) How would the task read the byte[] and reconstruct the original object? Thanks.

  • Does Java have an equivalent to .NET resource (.resx) files for localization?

    - by frankadelic
    Does Java have an equivalent to .NET resource (.resx) files for localization? In .NET, you can define resources as key-value pairs within a standard XML document. The resource files are named according to the culture. For example: myresources.resx myresources.en-us.resx myresources.fr-fr.resx myresources.de-de.resx Is there an equivalent in Java? Are the similar naming conventions used for files?

  • Are there reasons why the java/spring/hibernate stack aren't popular in the web 2.0 space?

    - by Blankman
    I am really impressed with the java/spring/hibernate stack, and really want to dive in. Just curious, why are so many people using rails when java/spring/hibernate are tried and true? I guesss its because of the convention over configuration and time to launch? (spring has really gone the annotation route so less xml though). I realize this is subjective, but just looking for some thoughts on this.
