• Expressing the UI for Enterprise Applications with JavaFX 2.0 FXML - Part One

  - by Janice J. Heiss

  A new article, the first of two parts, now up on otn/java by Oracle Evangelist and JavaFX expert, James L. Weaver, titled “Expressing the UI for Enterprise Applications with JavaFX 2.0 FXML, Part One,” shows developers how to leverage the power of the FX Markup Language (FXML) to define the UI in enterprise applications.As Weaver explains, “JavaFX 2.0 is an API and runtime for creating Rich Internet Applications (RIAs). JavaFX was introduced in 2007, and version 2.0 was released in October 2011. One of the advantages of JavaFX 2.0 is that the code can be written in the Java language using mature and familiar tools.”He goes on to show how to use the potential of FX Markup Language, which comes with JavaFX 2.0, to efficiently define the user interface for enterprise applications. FXML functions to enable the expression of the UI using XML. “Classes that contain FXML functionality are located in the javafx.fxml package,” says Weaver, “and they include FXMLLoader, JavaFXBuilderFactory, and an interface named Initializable.” Weaver’s article offers a sample application that shows how to use the capabilities of FXML and JavaFX 2.0 to create an enterprise app. Have a look at the article here.

• Dynamic endpoint binding in Oracle SOA Suite by Cattle Crew

  - by JuergenKress

  Why is dynamic endpoint binding needed? Sometimes a BPEL process instance has to determine at run-time which implementation of a web service interface is to be called. We’ll show you how to achieve that using dynamic endpoint binding. Let’s imagine the following scenario: we’re running a car rental agency called RYLC (Rent Your Legacy Car) which operates different locations. The process of renting a car is basically identical for all locations except for the determination which cars are currently available. This is depicted in the following diagram: There are three different implementations of the GetAvailableCars service. But how can we achieve calling them dynamically at run-time using Oracle SOA Suite? How to dynamically set the service endpoint There are just a couple of implementation steps we need to perform to enable dynamic endpoint binding: create a new SOA project in JDeveloper add a CarRental BPEL process add an external reference to the GetAvailableCars service within the composite create a DVM file containing the URI’s by which the services for the different locations can be accessed set the endpointURI property on the Invoke component calling the GetAvailableCars service (value is taken from the DVM file) Read the complete article here.

• unit/integration testing web service proxy client

  - by cori

  I'm rewriting a PHP client/proxy library that provides an interface to a SOAP-based .Net webservice, and in the process I want to add some unit and integration tests so future modifications are less risky. The work the library I'm working on performs is to marshall the calls to the web service and do a little reorganizing of the responses to present a slightly more -object-oriented interface to the underlying service. Since this library is little else than a thin layer on top of web service calls, my basic assumption is that I'll really be writing integration tests more than unit tests - for example, I don't see any reason to mock away the web service - the work that's performed by the code I'm working on is very light; it's almost passing the response from the service right back to its consumer. Most of the calls are basic CRUD operations: CreateRole(), CreateUser(), DeleteUser(), FindUser(), &ct. I'll be starting from a known database state - the system I'm using for these tests is isolated for testing purposes, so the results will be more or less predictable. My question is this: is it natural to use web service calls to confirm the results of operations within the tests and to reset the state of the application within the scope of each test? Here's an example: One test might be createUserReturnsValidUserId() and might go like this: public function createUserReturnsValidUserId() { // we're assuming a global connection to the service $newUserId = $client->CreateUser("user1"); assertNotNull($newUserId); assertNotNull($client->FindUser($newUserId); $client->deleteUser($newUserId); } So I'm creating a user, making sure I get an ID back and that it represents a user in the system, and then cleaning up after myself (so that later tests don't rely on the success or failure of this test w/r/t the number of users in the system, for example). However this still seems pretty fragile - lots of dependencies and opportunities for tests to fail and effect the results of later tests, which I definitely want to avoid. Am I missing some options of ways to decouple these tests from the system under test, or is this really the best I can do? I think this is a fairly general unit/integration testing question, but if it matters I'm using PHPUnit for the testing framework.

• Understanding Visitor Pattern

  - by Nezreli

  I have a hierarchy of classes that represents GUI controls. Something like this: Control-ContainerControl-Form I have to implement a series of algoritms that work with objects doing various stuff and I'm thinking that Visitor pattern would be the cleanest solution. Let take for example an algorithm which creates a Xml representaion of a hierarchy of objects. Using 'classic' approach I would do this: public abstract class Control { public virtual XmlElement ToXML(XmlDocument document) { XmlElement xml = document.CreateElement(this.GetType().Name); // Create element, fill it with attributes declared with control return xml; } } public abstract class ContainerControl : Control { public override XmlElement ToXML(XmlDocument document) { XmlElement xml = base.ToXML(document); // Use forech to fill XmlElement with child XmlElements return xml; } } public class Form : ContainerControl { public override XmlElement ToXML(XmlDocument document) { XmlElement xml = base.ToXML(document); // Fill remaining elements declared in Form class return xml; } } But I'm not sure how to do this with visitor pattern. This is the basic implementation: public class ToXmlVisitor : IVisitor { public void Visit(Form form) { } } Since even the abstract classes help with implementation I'm not sure how to do that properly in ToXmlVisitor. Perhaps there is a better solution to this problem. The reason that I'm considering Visitor pattern is that some algorithms will need references not available in project where the classes are implemented and there is a number of different algorithms so I'm avoiding large classes. Any thoughts are welcome.

• how to link a c++ object to a local variable in Lua

  - by MahanGM

  I'm completing my scripting interface with Lua, but recently I've stuck at some point. I have several functions for my Entitiy events like Update(). I have a function called create_entitiy() which instantiate a new entity from a given entity index: function Update() local bullet = create_entity(0, 0, "obj_bullet") end create_entity returns a table which is the properties of the created entity. Now how can I make a connection between bullet variable and my newly created object? Right now for previously added objects to the scene, I simply set a global table for each of them and then after every call to Update(), I go through registered names to find object tables and perform new changes. Like the one below: function Update() if keyboard_key_press(vk_right) then obj_player.x += 3 end I can get obj_player table because I know its name from C++, plus I can get it as a global table and simply reach for the first instance named obj_player. Is there any solution for me to make bullet variable act like this? I was thinking to get all local variables in Update() function and check for every one to see if is it table and it has an unique field attached to it like id, this way I can determine that this is an object table and do the rest of the process. By the way, is this interface going to work easier with luaBind if I implement it? Bottom line: How can I make a local variable in Lua that receives a table from create_entity function and track that local variable to capture it from C++. e. g. function Update() local bullet = create_entity(0, 0, "obj_bullet") bullet.x = 10 <== Commit a change in table end Now I want to get variable bullet from C++. And it's not just this variable, there might be a ton of these local variables with different names.

• What's the relationship between meta-circular interpreters, virtual machines and increased performance?

  - by Gomi

  I've read about meta-circular interpreters on the web (including SICP) and I've looked into the code of some implementations (such as PyPy and Narcissus). I've read quite a bit about two languages which made great use of metacircular evaluation, Lisp and Smalltalk. As far as I understood Lisp was the first self-hosting compiler and Smalltalk had the first "true" JIT implementation. One thing I've not fully understood is how can those interpreters/compilers achieve so good performance or, in other words, why is PyPy faster than CPython? Is it because of reflection? And also, my Smalltalk research led me to believe that there's a relationship between JIT, virtual machines and reflection. Virtual Machines such as the JVM and CLR allow a great deal of type introspection and I believe they make great use it in Just-in-Time (and AOT, I suppose?) compilation. But as far as I know, Virtual Machines are kind of like CPUs, in that they have a basic instruction set. Are Virtual Machines efficient because they include type and reference information, which would allow language-agnostic reflection? I ask this because many both interpreted and compiled languages are now using bytecode as a target (LLVM, Parrot, YARV, CPython) and traditional VMs like JVM and CLR have gained incredible boosts in performance. I've been told that it's about JIT, but as far as I know JIT is nothing new since Smalltalk and Sun's own Self have been doing it before Java. I don't remember VMs performing particularly well in the past, there weren't many non-academic ones outside of JVM and .NET and their performance was definitely not as good as it is now (I wish I could source this claim but I speak from personal experience). Then all of a sudden, in the late 2000s something changed and a lot of VMs started to pop up even for established languages, and with very good performance. Was something discovered about the JIT implementation that allowed pretty much every modern VM to skyrocket in performance? A paper or a book maybe?

• Add static ARP entries when network is brought up

  - by jozzas

  I have some pretty dumb IP devices on a subnet with my Ubuntu server, and the server receives streaming data from each device. I have run into a problem in that when an ARP request is issued to the device while it is streaming data to the server, the request is ignored, the cache entry times out and the server stops receiving the stream. So, to prevent the server from sending ARP requests to these devices altogether, I would like to add a static ARP entry for each, something like arp -i eth2 -s ip.of.the.device mac:of:the:device But these "static" ARP entries are lost if networking is disabled / enabled or if the server is rebooted. Where is the best place to automatically add these entries, preferably somewhere that will re-add them every time the interface eth2 is brought up? I really don't want to have to write a script that monitors the output of arp and re-adds the cache entries if they're missing. Edit to add what my final script was: Created the file /etc/network/if-up.d/add-my-static-arp With the contents: #!/bin/sh arp -i eth0 -s 192.168.0.4 00:50:cc:44:55:55 arp -i eth0 -s 192.168.0.5 00:50:cc:44:55:56 arp -i eth0 -s 192.168.0.6 00:50:cc:44:55:57 And then obviously add the permission to allow it to be executed: chmod +x /etc/network/if-up.d/add-my-static-arp And these arp entries will be manually added or re-added every time any network interface is brought up.

• How to Detect Sprites in a SpriteSheet?

  - by IAE

  I'm currently writing a Sprite Sheet Unpacker such as Alferds Spritesheet Unpacker. Now, before this is sent to gamedev, this isn't necessarily about games. I would like to know how to detect a sprite within a spriitesheet, or more abstactly, a shape inside of an image. Given this sprite sheet: I want to detect and extract all individual sprites. I've followed the algorithm detailed in Alferd's Blog Post which goes like: Determine predominant color and dub it the BackgroundColor Iterate over each pixel and check ColorAtXY == BackgroundColor If false, we've found a sprite. Keep going right until we find a BackgroundColor again, backtrack one, go down and repeat until a BackgroundColor is reached. Create a box from location to ending location. Repeat this until all sprites are boxed up. Combined overlapping boxes (or within a very short distance) The resulting non-overlapping boxes should contain the sprite. This implementation is fine, especially for small sprite sheets. However, I find the performance too poor for larger sprite sheets and I would like to know what algorithms or techniques can be leveraged to increase the finding of sprites. A second implementation I considered, but have not tested yet, is to find the first pixel, then use a backtracking algorithm to find every connected pixel. This should find a contiguous sprite (breaks down if the sprite is something like an explosion where particles are no longer part of the main sprite). The cool thing is that I can immediately remove a detected sprite from the sprite sheet. Any other suggestions?

• Did 12.04 just add multi-touch gesture support mid-release?

  - by adempewolff

  I was reviewing the updates I was about to download today and I noticed that a lot of them had to do with gesture support, noticed that many of these were new installs rather than upgrades. Has 12.04 just added multi-touch gesture support mid-release? If so, what are the capabilities that this adds? Which applications already support these capabilities and can I expect others to add support in the near future? Here are the packages that were installed: Install: libframe6:amd64 (2.2.4-0ubuntu0.12.04.1), libgeis1:amd64 (2.2.9.2-0ubuntu1), libgrail5:amd64 (3.0.6-0ubuntu0.12.04.01, automatic) And here are those that were upgraded (also including many with touch support): Upgrade: libgrip0:amd64 (0.3.4-0ubuntu2~ubuntu12.04.1, 0.3.5-0ubuntu1~12.04.1), eog:amd64 (3.4.2-0ubuntu1, 3.4.2-0ubuntu1.1), ginn:amd64 (0.2.4-0ubuntu1, 0.2.4.1-0ubuntu1) Of which the descriptions for the new installs are, libgeis1: Gesture engine interface support A common API for clients of a systemwide gesture recognition and propagation engine. libframe6: Touch Frame Library This library handles the buildup and synchronization of a set of simultaneous touches. The library is input agnostic, with bindings for mtdev, frame and XI2.1. libgrail5: Gesture Recognition And Instantiation Library This library consists of an interface and tools for handling gesture recognition and gesture instantiation. Applications can use the grail callbacks to receive gesture primitives and raw input events from the underlying kernel device. And the descriptions for the upgraded packages are, ligrip0: provides multitouch gestures to GTK+ apps Libgrip hooks gesture recognition into GTK+ applications. ginn: Gesture Injector: No-GEIS, No-Toolkits A daemon with jinn-like wish-granting capabilities: it gives applications the ability to support a subset of multi-touch gestures without having to integrate GEIS or multi-touch GTK/Qt libs. Adding in a ton of new libraries and upgrading the existing components makes me wonder if 12.04 is meant to start natively supporting gestures other than two finger scroll in the near future. I expected these capabilities to be introduced soon but I thought that they would only be rolled out in a new release, not as upgrades for an existing release. Anyone have any info about this?

• Message Driven Bean JMS integration

  - by Anthony Shorten

  In Oracle Utilities Application Framework V4.1 and above the product introduced the concept of real time JMS integration within the Framework for interfacing. Customer familiar with older versions of the Framework will recall that we used a component called the Multi-purpose Listener (MPL) which was a very light service bus for calling interface channels (including JMS). The MPL is not supplied with all products and customers prefer to use Oracle SOA Suite and native methods rather then MPL. In Oracle Utilities Application Framework V4.1 (and for Oracle Utilities Application Framework V2.2 via Patches 9454971, 9256359, 9672027 and 9838219) we introduced real time JMS integration natively for outbound JMS integration and using Message Driven Beans (MDB) for incoming integration. The outbound integration has not changed a lot between releases where you create an Outbound Message Type to indicate the record types to send out, create a JMS sender (though now you use the Real Time Sender) and then create an External System definition to complete the configuration. When an outbound message appears in the table of the type and external system configured (via a business event such as an algorithm or plug-in script) the Oracle Utilities Application Framework will place the message on the configured Queue linked to the JMS Sender. The inbound integration has changed. In the past you created XAI Receivers and specified configuration about what types of transactions to process. This is now all configuration file driven. The configuration files for the Business Application Server (ejb-jar.xml and weblogic-ejb-jar.xml) define Message Driven Beans and the queues to monitor. When a message appears on the queue, the MDB processes it through our web services interface. Configuration of the MDB can be native (via editing the configuration files) or through the new user exit capabilities (which is aimed at maintaining custom configuration across upgrades). The latter is better as you build fragments of configuration to make it easier to maintain. In the next few weeks a number of new whitepaper will be released to illustrate the features of the Oracle WebLogic JMS and Oracle SOA Suite integration capabilities.

• Cloning existing software for commercial purposes - legal implications

  - by user2036256

  I have been asked to clone some existing software for a company. Basically its an old 16 bit DOS console app, which was supplied free of charge in I believe the late 80's. Having replaced the machine that needs to run it with a box running Win7 x64 they can't get it to work. It crashes every couple of minutes under DOSbox. The company that supplied it appears to no longer exist - if they did the company asking me to do this would almost certainly know about it. Its undetermined whether they have gone entirely or are just trading under a different name. If the latter they seem to have withdrawn from the market related to this product (because again, niche area, we should know about everyone there). What is the status to this with regards to copyright etc.? The main concern for the company involved is they want an identical interface to what they already have so I would have to clone this entirely. Having no source code / indication of the underlying mechanisms these would be written from scratch. Is an interface covered by copyright? / Does that still hold 30 years later? What is the assumed license when none at all is provided? Under UK law would I be under any serious risk were I to take on the project? How would this pan out if I then decided to sell the software on to other companies? Thanks

  I am new to REST and am struggling to understand how one would properly design a REST system to both allow for loose coupling but at the same time allow a consumer of a REST API to understand the API. If, in my client code, I issue a GET request for a resource and get back XML, how do I know what to do with that xml? e.g. if it contains <fname>John</fname><lname>Smith</lname> how do I know that these refer to the concept of "first name", "last name"? Is it up to the person writing the REST API to define in documentation some place what each of the XML fields mean? What if producer of the API wants to change the implementation to be <firstname> instead of <fname>? How do they do this and notify their consumers that this change occurred? Or do the consumers just encounter the error and then look at the payload and figure out on their own that it changed? I've read in REST in Practice that using a WADL tool to create a client implementation based on the WADL (and hide the fact that you're doing a distributed call) is an "anti-pattern". But I was planning to do this-- at least then I would have a statically typed API call that, if it changed, I would know at compile time and not at run time. Why is this a bad thing to generate client code based on a WADL? And how do I know what to do with the links that returned in the response of a POST to a REST API? What defines this contract and gives true meaning to what each link will do? Please help! I dont understand how to go from statically-typed or even SOAP/RPC to REST!

• Game editor integration with the engine?

  - by Daniel

  What I am trying to figure out is what is the best way to integrate the editor(level, effects, model, etc...) in the most effective way? Now the first thing I thought would be to create the game engine(*) extremely modular. For example I took the example of game states. You could have multiple game states that all have their own update() and draw() methods among others. Each game state class would inherit from a base GameState class. This allows for a more modular approach and a useful one at that. Now would the most efficient approach be to implement the editor along with the modular engine, or create two different designs for both the game, and editor? I thought to take the game state example and extend it to window states, and well could be used for a lot more systems. Is there a better implementation of this design(game state) for use in other systems used in the engine? *: Now I know the term game engine is sorta irrelevant, and misused in many situations. What I am referring to as the "game engine" is the combination of the systems that the game must interact with for short. Also this is more of a theory / design question than an implementation. Even though both mix, i'd rather like to have a more general idea on how the editor is built in an efficient way and still using the same engine code as what the game uses. Thanks, Daniel P.S If you need more clarification or extra bits just leave a comment.

• Creating an expandable, cross-platform compatible program "core".

  - by Thomas Clayson

  Hi there. Basically the brief is relatively simple. We need to create a program core. An engine that will power all sorts of programs with a large number of distinct potential applications and deployments. The core will be an analytics and algorithmic processor which will essentially take user-specific input and output scenarios based on the information it gets, whilst recording this information for reporting. It needs to be cross platform compatible. Something that can have platform specific layers put on top which can interface with the core. It also needs to be able to be expandable, for instance, modular with developers being able to write "add-ons" or "extensions" which can alter the function of the end program and can use the core to its full extent. (For instance, a good example of what I'm looking to create is a browser. It has its main core, the web-kit engine, for instance, and then on top of this is has a platform-specific GUI and can also have add-ons and extensions which can change the behavior of the program.) Our problem is that the extensions need to interface directly with the main core and expand/alter that functionality rather than the platform specific "layer". So, given that I have no experience in this whatsoever (I have a PHP background and recently objective-c), where should I start, and is there any knowledge/wisdom you can impart on me please? Thanks for all the help and advice you can give me. :) If you need any more explanation just ask. At the moment its in the very early stages of development, so we're just researching all possible routes of development. Thanks a lot

• How do I install Postgres Graphical Installer?

  - by Tusar Das

  I am a newbie in using Ubuntu (more precisely never used linux except the production deployment ). Now I choose to hold a grip on the system and intalled a latest 11.10 Ubuntu in my 32 bit Intel** desktop. In this machine **I have a 'administrator' user 'tusar'. I want to install the PostgreSQL graphical version so downloaded this file postgresql-8.4.9-1-linux.bin from here Now If run the file with ./filename command (refuses if I am not root), it opens up the graphical interface and completes the installation (creates user postgres and ask for password, wont complete if I dont give valid password). I checked with /etc/inint.d/postgresql-8.4 status , that postgres is running. But the problem is I am unable to open the GUI (I installed it in /opt/Postgresql ), its telling permission denied even if I am logged in as 'tusar'. Then I tried using the su postgres command and it directly changed the user without password. Now if I run the psql , createdb , its prompting me to install the postgres-client-package but this utilies are already installed and I can view them in my /opt/Postgresql/8.4/bin folder. I can run query through my JDBC utility programs but unable to use neither terminal nor the graphical interface (although I can see pgAdmin3 is there ). Urgent help needed. I have used this guide for the installation.
