• Can you point me to a nontrivial strategy pattern implementation?

  - by Eugen Martynov

  We are faced implementing a registration workflow with many branches. There are three main flows which in some conditions lead to one another. Each flow has at least four different steps; some steps interact with the server, and every step adds more information to the state. Also the requirement is to have it persistent between sessions, so if the user closes the app (this is a mobile app), it will restore the process from the last completed step with the state from the previous session. I think this could benefit from the use of the strategy pattern, but I've never had to implement it for such a complex case. Does anyone know of any examples in open source or articles from which I could find inspiration? Preferably the examples would be from a live/working/stable application. I'm interested in Java implementation mostly; we are developing for Java mobile phones: android, blackberry and J2ME. We have an SDK which is quite well separated from platform specific implementations, but examples in C++, C#, Objective-C or Python would be acceptable.

• Book: DevOps for Developers

  - by Tori Wieldt

  We all know development and operations often act like silos, with "Just throw it over the wall!" being the battle cry. Many organizations unwittingly contribute to gaps between teams, with management by (competing) objectives; a clash of Agile practices vs. more conservative approaches; and teams using different sets of tools, such as Nginx, OpenEJB, and Windows on developers' machines and Apache, Glassfish, and Linux on production machines. At best, you've got sub-optimal collaboration, at worst, you've got the Hatfields and the McCoys.  The book DevOps for Developers helps bridge the gap between development and operations by aligning incentives and sharing approaches for processes and tools. It introduces DevOps as a modern way of bringing development and operations together. It also means to broaden the usage of Agile practices to operations to foster collaboration and streamline the entire software delivery process in a holistic way. Some single aspects of DevOps may not be new, for example, you may have used the tool Puppet for years already, but with a new mindset ("my job is not just to code, it's to serve the customer in the best way possible") and a complete set of recipes, you'll be well on your way to success. DevOps for Developers also by provides real-world use cases (e.g., how to use Kanban or how to release software). It provides a way to be successful in the real development/operations world. DevOps for Developers is written my Michael Hutterman, Java Champion, and founder of the Cologne Java User Group. "With DevOps for Developers, developers can learn to apply patterns to improve collaboration between development and operations as well as recipes for processes and tools to streamline the delivery process," Hutterman explains.

• Getting Started with GlassFish 4 and OEPE

  - by gstachni

  Oracle Enterprise Pack for Eclipse 12.1.1.2.2 introduces new support for GlassFish 4.0, the reference implementation of Java EE7.  Getting started with GlassFish 4.0 in Eclipse couldn't be easier. Follow these short steps to get GlassFish 4.0 setup so you can start developing, deploying, and debugging your Java EE7 applications. Prerequisites GlassFish 4.0 Oracle Enterprise Pack for Eclipse 12.1.1.2.2+ from OTN or Eclipse Marketplace Setting up the server connection In the Servers view, click to add a New > Server . Select GlassFish 4.0 from the list of supported server configurations. Pick your GlassFish installation directory (usually <glassfish 4>/glassfish) and select your domain. After you click Finish you should now be setup to launch Glassfish 4.0 in normal and debug mode within Eclipse as well as associate projects for deployment through the Add and Remove wizard. Using GlassFish tools in Eclipse GlassFish server tools provide some useful information about your running GlassFish 4.0 environment. Resources displays current resources deployed in the domain including your JDBC Connection Pool and JDBC Resource names. I find this extra bit of information useful when working with JPA. Deployed Applications shows the current active deployments in GlassFish which can be undeployed as needed from within Eclipse. Deployed Web Services provides information about SOAP-based web services deployed in this domain. Also with the running server are quick launch links to open the Administrative Console, Server Logs, and the GlassFish Community Site all within Eclipse's embedded browser.

• blender: 3D model from guide images

  - by Stefan

  In a effort to learn the blender interface, which is confusing to say the least, I've chosen to model a model from referrence pictures easily found on the web. Problem is that I can't ( and won't ) get perfect "right", "front" and "top" pictures. Blender only allows you to see the background pictures when in ortographic mode and only from right|front|top, which doesn't help me. How to I proceed to model from non-perfect guide images?

• Updating an Entity through a Service

  - by GeorgeK

  I'm separating my software into three main layers (maybe tiers would be a better term): Presentation ('Views') Business logic ('Services' and 'Repositories') Data access ('Entities' (e.g. ActiveRecords)) What do I have now? In Presentation, I use read-only access to Entities, returned from Repositories or Services, to display data. $banks = $banksRegistryService->getBanksRepository()->getBanksByCity( $city ); $banksViewModel = new PaginatedList( $banks ); // some way to display banks; // example, not real code I find this approach quite efficient in terms of performance and code maintanability and still safe as long as all write operations (create, update, delete) are preformed through a Service: namespace Service\BankRegistry; use Service\AbstractDatabaseService; use Service\IBankRegistryService; use Model\BankRegistry\Bank; class Service extends AbstractDatabaseService implements IBankRegistryService { /** * Registers a new Bank * * @param string $name Bank's name * @param string $bik Bank's Identification Code * @param string $correspondent_account Bank's correspondent account * * @return Bank */ public function registerBank( $name, $bik, $correspondent_account ) { $bank = new Bank(); $bank -> setName( $name ) -> setBik( $bik ) -> setCorrespondentAccount( $correspondent_account ); if( null === $this->getBanksRepository()->getDefaultBank() ) $this->setDefaultBank( $bank ); $this->getEntityManager()->persist( $bank ); return $bank; } /** * Makes the $bank system's default bank * * @param Bank $bank * @return IBankRegistryService */ public function setDefaultBank( Bank $bank ) { $default_bank = $this->getBanksRepository()->getDefaultBank(); if( null !== $default_bank ) $default_bank->setDefault( false ); $bank->setDefault( true ); return $this; } } Where am I stuck? I'm struggling about how to update certain fields in Bank Entity. Bad solution #1: Making a series of setters in Service for each setter in Bank; - seems to be quite reduntant, increases Service interface complexity and proportionally decreases it's simplicity - something to avoid if you care about code maitainability. I try to follow KISS and DRY principles. Bad solution #2: Modifying Bank directly through it's native setters; - really bad. If you'll ever need to move modification into the Service, it will be pain. Business logic should remain in Business logic layer. Plus, there are plans on logging all of the actions and maybe even involve user permissions (perhaps, through decorators) in future, so all modifications should be made only through the Service. Possible good solution: Creating an updateBank( Bank $bank, $array_of_fields_to_update) method; - makes the interface as simple as possible, but there is a problem: one should not try to manually set isDefault flag on a Bank, this operation should be performed through setDefaultBank method. It gets even worse when you have relations that you don't want to be directly modified. Of course, you can just limit the fields that can be modified by this method, but how do you tell method's user what they can and cannot modify? Exceptions?

• ApiChange Corporate Edition

  - by Alois Kraus

  In my inital announcement I could only cover a small subset what ApiChange can do for you. Lets look at how ApiChange can help you to fix bugs due to wrong usage of an Api within a fraction of time than it would take normally. It happens that software is tested and some bugs show up. One bug could be …. : We get way too man log messages during our test run. Now you have the task to find the most frequent messages and eliminate the Log calls from the source code. But what about the myriads other log calls? How can we check that the distribution of log calls is nearly equal across all developers? And if not how can we contact the developer to check his code? ApiChange can help you too connect these loose ends. It combines several information silos into one cohesive view. The picture below shows how it is able to fill the gaps. The public version does currently “only” parse the binaries and pdbs to give you for a –whousesmethod query the following colums: If it happens that you have Rational ClearCase (a source control system) in your development shop and an Active Directory in place then ApiChange will try to determine from the source file which was determined from the pdb the last check in user which should be present in your Active Directory. From there it is only a small hop to an LDAP query to your AD domain or the GC (Global Catalog) to get from the user name his Full name Email Phone number Department …. ApiChange will append this additional data all of your query results which contain source files if you add the –fileinfo option. As I said this is currently not enabled by default since the AD domain needs to be configured which are currently only some hard coded values in the SiteConstants.cs source file of ApiChange.Api.dll. Once you got this data you can generate metrics based on source file, developer, assembly, … and add additional data by drag and drop directly into the pivot tables inside Excel. This allows you to e.g. to generate a report which lists the source files with most log calls in descending order along with the developer name and email in the pivot table. Armed with this knowledge you can take meaningful measures e.g. to ask the developer if the huge number of log calls in this source file can be optimized. I am aware that this is a very specific scenario but it is a huge time saver when you are able to fill the missing gaps of information. ApiChange does this in an extensible way. namespace ApiChange.ExternalData {     public interface IFileInformationProvider     {         UserInfo GetInformationFromFile(string fileName);     } } It defines an interface where you can implement your custom information provider to close the gap between source control system and the real person I have to send an email to ask if his code needs a closer inspection.

• Are there any useful tools to mirror a mailman mailing list as a forum?

  - by mar10

  We have a mailman mailing list however as we all know this is not very user friendly in terms of searching the archives. I am looking at a way to enable the continued functionality of mailman while having a forum linked to it for a more friendly user-interface approach. Is there a forum application that lets you mirror the mailman service so that posts to mailman are sync'd into the forum and posts to the forum are sync'd to mailman?

• Monitor Processes' Memory Usage

  - by Alvin Sim

  We have an IBM P series box running AIX 5.3. This is our application server, whereby our J2EE application is running in Oracle's Applications Server (version 10g r2). At around 11pm till the next day 7am, we have shell scripts running, which executes Java class programs. Recently, this server has been experiencing some high memory usage, which caused some of the Java class programs throwing "Out of memory" exception . We normally use NMON to monitor the server's resources, such as CPU, I/O, memory, etc. But because of this OOM issue, we would like to know throughout the day, what are the processes which are running and how much memory each process consumed. NMON is not able to show this. Even with the "-T" parameter, it only shows the top processes and not all. Is there any thing we can use to monitor all the processes' memory?

• Migration of PowerBuilder application to multiplatform

  - by Alex Bibiano

  I developed a client/server application with PowerBuilder in the past for medical clinics and done maintenance for it until now. Now, some clients are asking me to develop a release for Mac/Linux and need some advice about what programming language/technology is best suited for it and the learning curve. It’s not a very very big program but I’m the only developer and have done it in my spare time. PowerBuilder is very productive for this kind of projects (database centric), but it’s not multiplatform and it’s hard to sell PowerBuilder application now days (web, .NET, java sells a lot better with his marketing). My programming skills: - I studied C and C++ in the past (university) but never used it on real projects - Have some Java experience but not in desktop applications - Some experience with Ruby on Rails for web projects - Good skills with PowerBuilder and C# (.NET) (there are my main developing languages) My first dilemma is if I change the desktop application to a web interface, but I think the user will lose some user-experience, and some doctors don’t have a clinic (they are alone at home with my software). I think installing a web application (with webserver) for one user will be overwhelming. If I continue developing desktop application, what is at the moment a good framework/toolset to learn having my skills? Somebody has had similar experiences? A lot of thanks

• How can I solve the same problems a CB-architecture is trying to solve without using hacks? [on hold]

  - by Jefffrey

  A component based system's goal is to solve the problems that derives from inheritance: for example the fact that some parts of the code (that are called components) are reused by very different classes that, hypothetically, would lie in a very different branch of the inheritance tree. That's a very nice concept, but I've found out that CBS is often hard to accomplish without using ugly hacks. Implementations of this system are often far from clean. But I don't want to discuss this any further. My question is: how can I solve the same problems a CBS try to solve with a very clean interface? (possibly with examples, there are a lot of abstract talks about the "perfect" design already). Here's an example I was going for before realizing I was just reinventing inheritance again: class Human { public: Position position; Movement movement; Sprite sprite; // other human specific components }; class Zombie { Position position; Movement movement; Sprite sprite; // other zombie specific components }; After writing that I realized I needed an interface, otherwise I would have needed N containers for N different types of objects (or to use boost::variant to gather them all together). So I've thought of polymorphism (move what systems do in a CBS design into class specific functions): class Entity { public: virtual void on_event(Event) {} // not pure virtual on purpose virtual void on_update(World) {} virtual void on_draw(Window) {} }; class Human { private: Position position; Movement movement; Sprite sprite; public: virtual void on_event(Event) { ... } virtual void on_update(World) { ... } virtual void on_draw(Window) { ... } }; class Zombie { private: Position position; Movement movement; Sprite sprite; public: virtual void on_event(Event) { ... } virtual void on_update(World) { ... } virtual void on_draw(Window) { ... } }; Which was nice, except for the fact that now the outside world would not even be able to know where a Human is positioned (it does not have access to its position member). That would be useful to track the player position for collision detection or if on_update the Zombie would want to track down its nearest human to move towards him. So I added const Position& get_position() const; to both the Zombie and Human classes. And then I realized that both functionality were shared, so it should have gone to the common base class: Entity. Do you notice anything? Yes, with that methodology I would have a god Entity class full of common functionality (which is the thing I was trying to avoid in the first place).

• How do I run a beanshell script on my Mac?

  - by jonalv

  My Ubuntu-friend told me to testrun a Beanshell script by doing: bsh #filename# and when I told him that I don't know what bsh is nor have it he told me: sudo apt-get install bsh Being on a Mac I instead ran: sudo port install beanshell But still no bsh command available. A listing of the package content revealed a jar file named: /opt/local/share/java/bsh.jar but when I try to run that with my script file a complete Window manager written in Java starts up (and does not run the script file btw). Now, clearly I am doing something wrong, I am sure there must be a way of running beanshell scripts on a mac terminal although it does seem more natural for the linux users. What am I doing wrong and what should I do to run that script?

• Making Modular, Reusable and Loosely Coupled MVC Components

  - by Dusan

  I am building MVC3 application and need some general guidelines on how to manage complex client side interaction between my components. Here is my definition of one component in general way: Component which has it's own controller, model and view. All of the component's logic is placed inside these three parts and component is sort of "standalone", it contains it's own form, data needed for interaction, updates itself with Ajax and so on. Beside this internal logic and behavior of the component, it needs to be able to "Talk" to the outside world. By this I mean it should provide data and events (sort of) so when this component gets embedded in pages can notify other components which then can update based on the current state and data. I have an idea to use client ViewModel (in java-script) which would hookup all relevant components on page and control interaction between them. This would make components reusable, modular - independent of the context in which they are used. How would you do this, I am a bit stuck as I do not know if this is a good approach and there is a technical possibility to achieve this using java-script/jquery. The confusing part is about update via Ajax, how to ensure that component is properly linked to ViewModel when component is Ajax updated (or even worse removed or dynamically added). Also, how should this ViewModel be constructed and which technicalities to use here and in components to work as synergy??? On the web, I have found the various examples of the similar approach, but they are oversimplified (even for dummies) or over specific and do not provide valuable resource or general solution for this kind of implementation. If you have some serious examples it would be, also, very helpful. Note: My aim is to make interactions between many components on the same page simpler and more robust and elegant.

• Handy Tool for Code Cleanup: Automated Class Element Reordering

  - by Geertjan

  You're working on an application and this thought occurs to you: "Wouldn't it be cool if I could define rules specifying that all static members, initializers, and fields should always be at the top of the class? And then, whenever I wanted to, I'd start off a process that would actually do the reordering for me, moving class elements around, based on the rules I had defined, automatically, across one or more classes or packages or even complete code bases, all at the same time?" Well, here you go: That's where you can set rules for the ordering of your class members. A new hint (i.e., new in NetBeans IDE 7.3), which you need to enable yourself because by default it is disabled, let's the IDE show a hint in the Java Editor whenever there's code that isn't ordered according to the rules you defined: The first element in a file that the Java Editor identifies as not matching your rules gets a lightbulb hint shown in the left sidebar: Then, when you click the lightbulb, automatically the file is reordered according to your defined rules. However, it's not much fun going through each file individually to fix class elements as shown above. For that reason, you can go to "Refactor | Inspect and Transform". There, in the "Inspect and Transform" dialog, you can choose the hint shown above and then specify that you'd like it to be applied to a scope of your choice, which could be a file, a package, a project, combinations of these, or all of the open projects, as shown below: Then, when Inspect is clicked, the Refactoring window shows all the members that are ordered in ways that don't conform to your rules: Click "Do Refactoring" above and, in one fell swoop, all the class elements within the selected scope are ordered according to your rules.

• Logging off does not kill process in Windows Server 2003

  - by Suraj Chandran

  I have a Windows Server 2003(Enterprise, SP2). My understanding was that any process created by a user will be terminated when the user loggs off the account. But its not happening. I login via Administrator account. Start a simple java process and logoff. But the process is not killed. Is there any configuration for this or something? I am mostly a software programmer and not much in to servers and so I am stuck. I found out that while logging off, 1) Win32 is supposed to send a CTRL_LOGOFF_EVENT to all processes started by that user. 2) JVM is supposed to handle this event and terminate the VM. But I can't understand why my java process is not killed when i logoff. Any idea!!!
