Alternate Payments We've seen several alternate payment schemes emerge over the last two years, and 2011 may be the year one of them takes hold. Any competition that can drive down fees will be good for everyone. I'm betting that Apple will add NFC chips to their next version of the iPhone, then enable payments in stores using iTunes accounts on the backend. Paypal will continue to make inroads, and Isis will announce a pilot. The iPhone 4S did not contain an NFC chip, so we’ll have to continuing waiting for the iPhone 5. PayPal announced its moving into in-store payments, and Google launched its wallet in selected cities.  Overall I think the payment scene is heating up and that trend will continue. 2. Engineered Systems The industry is moving toward purpose-built appliances that are optimized across the entire stack. Oracle calls these "engineered systems" and the first two examples are Exadata and Exalogic, but there are other examples from other vendors. These are particularly important to the retail industry because of the volume of data that must be processed. There should be continued adoption in 2011. Oracle reports that Exadata is its fasting growing product, and at the recent OpenWorld it announced the SuperCluster and Exalytics products, both continuing the engineered systems trend. SAP’s HANA continues to receive attention, and IBM also seems to be moving in this direction. 3. Social Analytics There are lots of tools that provide insight into how a brand is perceived across popular internet sites, but as far as I know, these tools are not industry specific. The next step needs to mine the data and determine how it should influence retail operations. The data needs to help retailers determine how they create promotions, which products to stock, and how to keep consumers engaged. Social data alone does not provide the answers, but its one more data point that will help retailers make better decisions. Look for some vendor consolidation to help make this happen. In March, Salesforce.com acquired leading social monitoring vendor Radian6 and followed up with acquisitions of Heroku and Model Metrics. The notion of Social CRM seems to be going more mainstream now. 4. 2-D Barcodes Look for more QRCodes on shelf-tags, in newspaper circulars, and on billboards. It's a great portal from the physical world into the digital one that buys us time until augmented reality matures further. Nobody wants to type "www", backslash, and ".com" on their phones. QRCodes are everywhere. ‘Nuff said. 5. In the words of Microsoft, "To the Cloud!" My favorite "cloud application" is Evernote. If you take notes on your work laptop, you will inevitably need those notes on your home PC. And if you manage to solve that problem, you'll need to access them from your mobile phone. Evernote stores your notes in the cloud and provides easy ways to access them. Being able to access a service from anywhere and not having to worry about backups, upgrades, etc. is great. Retailers will start to rely on cloud services, both public and private, in the coming year. There were no shortage of announcements in this area: Amazon’s cloud-based Kindle Fire, Apple’s iCloud, Oracle’s Public Cloud, etc. I saw an interesting presentation showing how BevMo moved their systems to the cloud.  Seems like retailers are starting to consider the cloud for specific uses. 6. F-CommerceTop of Form Move over "E" and "M" so we can introduce "F-Commerce," which should go mainstream in 2011. Already several retailers have created small stores on Facebook, and it won't be long before Facebook becomes a full-fledged channel in the omni-channel world of retail. The battle between Facebook and Google will heat up over retail, where both stand to make lots of money. JCPenney and ASOS both put their entire catalogs on Facebook, and lots of other retailers have connected Facebook to their e-commerce site. I still think selling from the newsfeed is the best approach, and several retailers are trying that approach as well. I just don’t see Google+ as a threat to Facebook, so I think that battle is over.  I called 2011 The Year of F-Commerce, and that was probably accurate. Its good to look back at predictions, but we also have to think about what was missed.  I didn't see Amazon entering the tablet business with such a splash, although in hindsight it was obvious. Nor did I think HP would fall so far so fast.  Look for my 2012 predictions coming soon.

  • Java Jersey RESTful services

    - by pHk
    Rather new to REST and Jersey, and I'm trying out some basic examples. I've got one particular question though, which I haven't really found an answer for yet (don't really know how to look for this): how would you go about storing/defining common services so that they are stateful and accessible to all/some resources? For instance, a logger instance (Log4J or whatever). Do I have to manually initialize this and store it in the HttpSession? Is there a "best practice" way of doing this so that my logger is accessible to all/some resources? Thanks a lot.

  • Key ATG architecture principles

    - by Glen Borkowski
    Overview The purpose of this article is to describe some of the important foundational concepts of ATG.  This is not intended to cover all areas of the ATG platform, just the most important subset - the ones that allow ATG to be extremely flexible, configurable, high performance, etc.  For more information on these topics, please see the online product manuals. Modules The first concept is called the 'ATG Module'.  Simply put, you can think of modules as the building blocks for ATG applications.  The ATG development team builds the out of the box product using modules (these are the 'out of the box' modules).  Then, when a customer is implementing their site, they build their own modules that sit 'on top' of the out of the box ATG modules.  Modules can be very simple - containing minimal definition, and perhaps a small amount of configuration.  Alternatively, a module can be rather complex - containing custom logic, database schema definitions, configuration, one or more web applications, etc.  Modules generally will have dependencies on other modules (the modules beneath it).  For example, the Commerce Reference Store module (CRS) requires the DCS (out of the box commerce) module. Modules have a ton of value because they provide a way to decouple a customers implementation from the out of the box ATG modules.  This allows for a much easier job when it comes time to upgrade the ATG platform.  Modules are also a very useful way to group functionality into a single package which can be leveraged across multiple ATG applications. One very important thing to understand about modules, or more accurately, ATG as a whole, is that when you start ATG, you tell it what module(s) you want to start.  One of the first things ATG does is to look through all the modules you specified, and for each one, determine a list of modules that are also required to start (based on each modules dependencies).  Once this final, ordered list is determined, ATG continues to boot up.  One of the outputs from the ordered list of modules is that each module can contain it's own classes and configuration.  During boot, the ordered list of modules drives the unified classpath and configpath.  This is what determines which classes override others, and which configuration overrides other configuration.  Think of it as a layered approach. The structure of a module is well defined.  It simply looks like a folder in a filesystem that has certain other folders and files within it.  Here is a list of items that can appear in a module: MyModule: META-INF - this is required, along with a file called MANIFEST.MF which describes certain properties of the module.  One important property is what other modules this module depends on. config - this is typically present in most modules.  It defines a tree structure (folders containing properties files, XML, etc) that maps to ATG components (these are described below). lib - this contains the classes (typically in jarred format) for any code defined in this module j2ee - this is where any web-apps would be stored. src - in case you want to include the source code for this module, it's standard practice to put it here sql - if your module requires any additions to the database schema, you should place that schema here Here's a screenshots of a module: Modules can also contain sub-modules.  A dot-notation is used when referring to these sub-modules (i.e. MyModule.Versioned, where Versioned is a sub-module of MyModule). Finally, it is important to completely understand how modules work if you are going to be able to leverage them effectively.  There are many different ways to design modules you want to create, some approaches are better than others, especially if you plan to share functionality between multiple different ATG applications. Components A component in ATG can be thought of as a single item that performs a certain set of related tasks.  An example could be a ProductViews component - used to store information about what products the current customer has viewed.  Components have properties (also called attributes).  The ProductViews component could have properties like lastProductViewed (stores the ID of the last product viewed) or productViewList (stores the ID's of products viewed in order of their being viewed).  The previous examples of component properties would typically also offer get and set methods used to retrieve and store the property values.  Components typically will also offer other types of useful methods aside from get and set.  In the ProductViewed component, we might want to offer a hasViewed method which will tell you if the customer has viewed a certain product or not. Components are organized in a tree like hierarchy called 'nucleus'.  Nucleus is used to locate and instantiate ATG Components.  So, when you create a new ATG component, it will be able to be found 'within' nucleus.  Nucleus allows ATG components to reference one another - this is how components are strung together to perform meaningful work.  It's also a mechanism to prevent redundant configuration - define it once and refer to it from everywhere. Here is a screenshot of a component in nucleus:  Components can be extremely simple (i.e. a single property with a get method), or can be rather complex offering many properties and methods.  To be an ATG component, a few things are required: a class - you can reference an existing out of the box class or you could write your own a properties file - this is used to define your component the above items must be located 'within' nucleus by placing them in the correct spot in your module's config folder Within the properties file, you will need to point to the class you want to use: $class=com.mycompany.myclass You may also want to define the scope of the class (request, session, or global): $scope=session In summary, ATG Components live in nucleus, generally have links to other components, and provide some meaningful type of work.  You can configure components as well as extend their functionality by writing code. Repositories Repositories (a.k.a. Data Anywhere Architecture) is the mechanism that ATG uses to access data primarily stored in relational databases, but also LDAP or other backend systems.  ATG applications are required to be very high performance, and data access is critical in that if not handled properly, it could create a bottleneck.  ATG's repository functionality has been around for a long time - it's proven to be extremely scalable.  Developers new to ATG need to understand how repositories work as this is a critical aspect of the ATG architecture.   Repositories essentially map relational tables to objects in ATG, as well as handle caching.  ATG defines many repositories out of the box (i.e. user profile, catalog, orders, etc), and this is comprised of both the underlying database schema along with the associated repository definition files (XML).  It is fully expected that implementations will extend / change the out of the box repository definitions, so there is a prescribed approach to doing this.  The first thing to be sure of is to encapsulate your repository definition additions / changes within your own module (as described above).  The other important best practice is to never modify the out of the box schema - in other words, don't add columns to existing ATG tables, just create your own new tables.  These will help ensure you can easily upgrade your application at a later date. xml-combination As mentioned earlier, when you start ATG, the order of the modules will determine the final configpath.  Files within this configpath are 'layered' such that modules on top can override configuration of modules below it.  This is the same concept for repository definition files.  If you want to add a few properties to the out of the box user profile, you simply need to create an XML file containing only your additions, and place it in the correct location in your module.  At boot time, your definition will be combined (hence the term xml-combination) with the lower, out of the box modules, with the result being a user profile that contains everything (out of the box, plus your additions).  Aside from just adding properties, there are also ways to remove and change properties. types of properties Aside from the normal 'database backed' properties, there are a few other interesting types: transient properties - these are properties that are in memory, but not backed by any database column.  These are useful for temporary storage. java-backed properties - by nature, these are transient, but in addition, when you access this property (by called the get method) instead of looking up a piece of data, it performs some logic and returns the results.  'Age' is a good example - if you're storing a birth date on the profile, but your business rules are defined in terms of someones age, you could create a simple java-backed property to look at the birth date and compare it to the current date, and return the persons age. derived properties - this is what allows for inheritance within the repository structure.  You could define a property at the category level, and have the product inherit it's value as well as override it.  This is useful for setting defaults, with the ability to override. caching There are a number of different caching modes which are useful at different times depending on the nature of the data being cached.  For example, the simple cache mode is useful for things like user profiles.  This is because the user profile will typically only be used on a single instance of ATG at one time.  Simple cache mode is also useful for read-only types of data such as the product catalog.  Locked cache mode is useful when you need to ensure that only one ATG instance writes to a particular item at a time - an example would be a customers order.  There are many options in terms of configuring caching which are outside the scope of this article - please refer to the product manuals for more details. Other important concepts - out of scope for this article There are a whole host of concepts that are very important pieces to the ATG platform, but are out of scope for this article.  Here's a brief description of some of them: formhandlers - these are ATG components that handle form submissions by users. pipelines - these are configurable chains of logic that are used for things like handling a request (request pipeline) or checking out an order. special kinds of repositories (versioned, files, secure, ...) - there are a couple different types of repositories that are used in various situations.  See the manuals for more information. web development - JSP/ DSP tag library - ATG provides a traditional approach to developing web applications by providing a tag library called the DSP library.  This library is used throughout your JSP pages to interact with all the ATG components. messaging - a message sub-system used as another way for components to interact. personalization - ability for business users to define a personalized user experience for customers.  See the other blog posts related to personalization.

  • Google App Engine - low-level datastore API flag?

    - by Keyur
    In my GAE-Java app, I'm using the low-level datastore API. Hence I don't need the GAE app instance to load any of the higher level data access libraries such as JPA, JDO, Data Nucleus, etc. Is there a flag that I can set to indicate that I don't want these libraries to be loaded? My motivation to do this is to reduce app instance startup time everywhere I can. Now I don't know if these libraries are loaded only on-demand or always. The dev environment logs messages related to data nucleus which seems to indicate that some of these libraries may be pre-loaded? I hope I'm wrong here. Thanks, Keyur

  • Need to get back form controls' information externally

    - by Tom
    Are there any tutorials or guides out there that anyone knows of that will show me how to read forms from an external program and get back information about the controls on the form? Currently, I can get the handle to the form, and I can get the class name, but I need to get more information such as a persistent name and contained data. Thanks. Edit: I now have a way to read the contained data (with the WM_GETTEXT message), however, I still need a persistent name/ID that I can be sure will not change from instance to instance. One way I can think of for doing this is to take the handle, find the position of the control on the window, and then get the handle from the position from then on. Another way is to determine a static ID for the control and then use that to get the handle from then on. The new scope of my problem is how to implement either of these. Any Ideas?

  • Write to static field - is FindBugs wrong in this case?

    - by htorque
    I have a Java class like this: public class Foo { public static int counter = 0; public void bar(int counter) { Foo.counter = counter; } } FindBugs warns me about writing to the static field counter via the instance method bar. However, if I change the code to: public class Foo { public static int counter = 0; public static void setCounter(int counter) { Foo.counter = counter; } public void bar(int counter) { setCounter(counter); } } Then FindBugs won't complain. Isn't that wrong? I'm still writing to a static field from an instance method, just via a static method - no?

  • How to query a date in HQL (Hibernate) with Joda Time?

    - by fabien7474
    I am sure that someone familiar with HQL (I am myself a newbie) can easily answer this question. In my Grails application, I have the following domain class. class Book { org.joda.time.DateTime releaseDate //I use the PersistentDateTime for persisting via Hibernate (that use a DATETIME type for MySQL DB) } In my HQL query, I want to retrieve books whose release date is included in range date1..date2 For instance I tried: DateTime date1, date2 ... def queryStr = "select * from Book as b where b.releaseDate > $date1 and b.releaseDate < $date2" def res = Book.executeQuery(queryStr) But I got the exception ...caused by: org.springframework.orm.hibernate3.HibernateQueryException: unexpected token: The error token points to date format (for instance 2009-11-27T21:57:18.010+01:00 or Fri Nov 27 22:01:20 CET 2009) I have also tried to convert date1 into a Date class without success So what is the correct HQL code ? Should I convert to a specific format (which one?) using the patternForStyle method or is there another -cleaner- way to do it? Thanks, Fabien.

  • Programming mid-terms

    - by Dervin Thunk
    Hello. Unfortunately, (written) midterms are necessary in most university CS programs in the world. They tell us how well our students (and ourselves as teachers) are doing. Needless to say, designing midterms for a C Programming Language course is not easy. For instance, when we do program for real, we have a myriad of information at our disposal: websites, books, cheat sheets to "remember" the syntax and so on. My question is this: did you find any way, during your years at school or training, where you said: ok, this midterm evaluation of my programming skills is tough, but fair. For instance: I found "find 5 problems with this code"-type questions hard but interesting and telling. Are there any others? Thanks.

    Considering this xml document: DECLARE @X XML (DOCUMENT search.SearchParameters) = '< parameters xmlns="http://www.educations.com/Search/Parameters.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> < parameter xsi:type="category" categoryID="38" /> < /parameters>'; I'd like to access the value of the attribute "type". According to this blog post, the xsi:type attribute is special and can't be accessed by usal keywords/functions. How can I do it? PS: I tried with WITH XMLNAMESPACES ( 'http://www.educations.com/Search/Parameters.xsd' as p, 'http://www.w3.org/2001/XMLSchema-instance' as xsi ) SELECT @X.value('(/p:parameters/p:parameter/@xsi:type)[1]','nvarchar(max)') but it didn't work.

  • c# application and configuration settings

    - by Maks
    Hi, I never used Settings class before but I found some articles on CodeProject which I'm currently reading (for example http://www.codeproject.com/KB/cs/PropertiesSettings.aspx) but so far I didn't see how to save string array for getting it after application is started next time. For example my application has several FileSystemWatcher instances, with each instance several other directories are connected (for example one FSW instance is monitoring one directory for a change and when it happens it copies some file to several other directories), so I would have one string array with watched paths representing FSW instances, and string array for each of those paths, representing directories that are affected. My question is, what should I use (Settings class or something else), and how should I use that for storing application configuration that is variable number of string arrays? Emphasize is on something I could use very soon as I don't have too much time to make custom class (but would have to if I cannot find solution) or dig into some obscure hacks. Any tutorial link, code snippet would be very helpful. Thanks.

    So far I have the below which is taken from http://www.danielmoth.com/Blog/volatile-registrykey.aspx public static class RegistryHelper { public static RegistryKey CreateVolatileSubKey(RegistryKey rk, string subkey, RegistryKeyPermissionCheck permissionCheck) { var rk2 = rk.GetType(); const BindingFlags bfStatic = BindingFlags.NonPublic | BindingFlags.Static; const BindingFlags bfInstance = BindingFlags.NonPublic | BindingFlags.Instance; rk2.GetMethod("ValidateKeyName", bfStatic).Invoke(null, new object[] { subkey }); rk2.GetMethod("ValidateKeyMode", bfStatic).Invoke(null, new object[] { permissionCheck }); rk2.GetMethod("EnsureWriteable", bfInstance).Invoke(rk, null); subkey = (string)rk2.GetMethod("FixupName", bfStatic).Invoke(null, new object[] { subkey }); if (!(bool)rk2.GetField("remoteKey", bfInstance).GetValue(rk)) { var key = (RegistryKey)rk2.GetMethod("InternalOpenSubKey", bfInstance, null, new[] { typeof(string), typeof(bool) }, null).Invoke(rk, new object[] { subkey, permissionCheck != RegistryKeyPermissionCheck.ReadSubTree }); if (key != null) { rk2.GetMethod("CheckSubKeyWritePermission", bfInstance).Invoke(rk, new object[] { subkey }); rk2.GetMethod("CheckSubTreePermission", bfInstance).Invoke(rk, new object[] { subkey, permissionCheck }); rk2.GetField("checkMode", bfInstance).SetValue(key, permissionCheck); return key; } } rk2.GetMethod("CheckSubKeyCreatePermission", bfInstance).Invoke(rk, new object[] { subkey }); int lpdwDisposition; IntPtr hkResult; var srh = Type.GetType("Microsoft.Win32.SafeHandles.SafeRegistryHandle"); var temp = rk2.GetField("hkey", bfInstance).GetValue(rk); var rkhkey = (SafeHandleZeroOrMinusOneIsInvalid)temp; var getregistrykeyaccess = (int)rk2.GetMethod("GetRegistryKeyAccess", bfStatic, null, new[] { typeof(bool) }, null).Invoke(null, new object[] { permissionCheck != RegistryKeyPermissionCheck.ReadSubTree }); var errorCode = RegCreateKeyEx(rkhkey, subkey, 0, null, 1, getregistrykeyaccess, IntPtr.Zero, out hkResult, out lpdwDisposition); var keyNameField = rk2.GetField("keyName", bfInstance); var rkkeyName = (string)keyNameField.GetValue(rk); if (errorCode == 0 && hkResult.ToInt32() > 0) { var rkremoteKey = (bool)rk2.GetField("remoteKey", bfInstance).GetValue(rk); var hkResult2 = srh.GetConstructor(BindingFlags.Instance | BindingFlags.NonPublic, null, new[] { typeof(IntPtr), typeof(bool) }, null).Invoke(new object[] { hkResult, true }); var key2 = (RegistryKey)rk2.GetConstructor(BindingFlags.Instance | BindingFlags.NonPublic, null, new[] { hkResult2.GetType(), typeof(bool), typeof(bool), typeof(bool), typeof(bool) }, null).Invoke(new[] { hkResult2, permissionCheck != RegistryKeyPermissionCheck.ReadSubTree, false, rkremoteKey, false }); rk2.GetMethod("CheckSubTreePermission", bfInstance).Invoke(rk, new object[] { subkey, permissionCheck }); rk2.GetField("checkMode", bfInstance).SetValue(key2, permissionCheck); if (subkey.Length == 0) { keyNameField.SetValue(key2, rkkeyName); } else { keyNameField.SetValue(key2, rkkeyName + @"\" + subkey); } key2.Close(); return rk.OpenSubKey(subkey, true); } if (errorCode != 0) rk2.GetMethod("Win32Error", bfInstance).Invoke(rk, new object[] { errorCode, rkkeyName + @"\" + subkey }); return null; } [DllImport("advapi32.dll", CharSet = CharSet.Auto)] private static extern int RegCreateKeyEx(SafeHandleZeroOrMinusOneIsInvalid hKey, string lpSubKey, int reserved, string lpClass, int dwOptions, int samDesigner, IntPtr lpSecurityAttributes, out IntPtr hkResult, out int lpdwDisposition); } Which works but is fairly ugly. Is there a better way?

  • WCF client proxy initialization

    - by 123Developer
    I am consuming a WCF service and created its proxy using the VS 2008 service reference. I am looking for the best pattern to call WCF service method Should I create the client proxy instance every time I call the service method and close the client as soon as I am done with that? When I profiled my client application, I could see that it is taking lot of time to get the Channel while initializing the proxy client Should I use a Singleton pattern for the client proxy so that I can use the only once instance and get rid of the re-initializing overhead? Is there any hidden problem with this approach? I am using .Net framework 3.5 SP1, basicHttp binding with little customization.

  • How is it that the abstract class XmlWriter can be instantiated using XmlWriter.Create(... ?

    - by Cognize
    Hi, Just looking to clarify my understanding of the workings of the XmlWriter and abstract classes in general. My thinking is (was) that an abstract class can not be instantiated, although it can contain base methods that can be used by an inheriting class. So, while investigating XmlWriter, I find that to instantiate the XmlWriter, you call XmlWriter.Create(.... , which returns an instance of... XmlWriter, which can then be used: FileStream fs = new FileStream("XML.xml", FileMode.Create); XmlWriter w = XmlWriter.Create(fs); XmlSerializer xmlSlr = new XmlSerializer(typeof(TestClass)); xmlSlr.Serialize(fs, tsIn); This clearly works, as tested. Can anyone help me understand what is going on here. As far as I can see there is or should be no 'instance' to work with here??

  • State pattern: Why doesn't the context class implement or inherit the State abstract interface/class

    - by Ricket
    I'm reading about the State pattern. I have only just begun, so of course I begin by reading the entire Wikipedia article on it. I noticed that both of the examples in the article have some base abstract class or Java interface for a generic State's methods/functions. Then there are some states which inherit from the base and implement those methods/functions in different ways. Then there's a Context class which has a private member of type State and which, at any time, can be equal to an instance of one of the implementations. That context class also implements the same methods, and passes them onto the current state instance, and then has an additional method to change the state (or depending on design I understand the change of state could be a reaction to one of the implemented methods). Why doesn't this context class specifically "extend" or "implement" the generic State base class/interface?

  • Subversion for version control

    - by Gabriel Parenza
    Hi, I am working on an application whose primary purpose would be to provide source control management. My idea is to use to SVNKit for file check-out and check-in. However, while working with SVNKit, I realised it does not have the speed I was looking for. For instance, whenever developers create a ChangeRequest, which can encompass change in 3-40 files, I have to create a directory structure distributed across 32 folders. Doing so takes around 50 seconds, Another instance is that after creating change request developers can add files to the request. Copying even a single file from Trunk to branch takes around 6-7 secs. My question is has anyone had experience like this and what did you do to improve the performance? Moreover, is my approach correct? NOTE: I am using "http" protocol and can't use "svn" protocol.

  • Wondering about a way to conserve memory in C# using List<> with structs

    - by Michael Ryan
    I'm not even sure how I should phrase this question. I'm passing some CustomStruct objects as parameters to a class method, and storing them in a List. What I'm wondering is if it's possible and more efficient to add multiple references to a particular instance of a CustomStruct if a equivalent instance it found. This is a dummy/example struct: public struct CustomStruct { readonly int _x; readonly int _y; readonly int _w; readonly int _h; readonly Enum _e; } Using the below method, you can pass one, two, or three CustomStruct objects as parameters. In the final method (that takes three parameters), it may be the case that the 3rd and possibly the 2nd will have the same value as the first. List<CustomStruct> _list; public void AddBackground(CustomStruct normal) { AddBackground(normal, normal, normal); } public void AddBackground(CustomStruct normal, CustomStruct hover) { AddBackground(normal, hover, hover); } public void AddBackground(CustomStruct normal, CustomStruct hover, CustomStruct active) { _list = new List<CustomStruct>(3); _list.Add(normal); _list.Add(hover); _list.Add(active); } As the method stands now, I believe it will create new instances of CustomStruct objects, and then adds a reference of each to the List. It is my understanding that if I instead check for equality between normal and hover and (if equal) insert normal again in place of hover, when the method completes, hover will lose all references and eventually be garbage collected, whereas normal will have two references in the List. The same could be done for active. That would be better, right? The CustomStruct is a ValueType, and therefore one instance would remain on the Stack, and the three List references would just point to it. The overall List size is determined not by the object Type is contains, but by its Capacity. By eliminating the "duplicate" CustomStuct objects, you allow them to be cleaned up. When the CustomStruct objects are passed to these methods, new instances are created each time. When the structs are added to the List, is another copy made? For example, if i pass just one CustomStruct, AddBackground(normal) creates a copy of the original variable, and then passes it three times to Addbackground(normal, hover, active). In this method, three copies are made of the original copy. When the three local variables are added to the List using Add(), are additional copies created inside Add(), and does that defeat the purpose of any equality checks as previously mentioned? Am I missing anything here?

  • Sql Server copying table information between databases

    - by Andrew
    Hi, I have a script that I am using to copy data from a table in one database to a table in another database on the same Sql Server instance. The script works great when I am connected to the Sql Server instance as myself as I have dbo access to both databases. The problem is that this won't be the case on the client's Sql Server. They have seperate logins for each database (Sql Authentication Logins). Does anyone know if there is a way to run a script under these circumstances. The script would be doing something like. use sourceDB Insert targetDB.dbo.tblTest (id, test_name) Select id, test_name from dbo.tblTest Thanks

  • Java: using endpoint to publish webservice to tomcat server

    - by Will
    hi all, i am creating a simple SOAP web service. i am to ensure that it runs on a tomcat web service. im trying to implement this with JAX-WS (see code) my question is: does the Endpoint.publish use the tomcat server to host this or is it a mini glassfish kind of server? should i be extending UnicastRemoveObject or something similiar instead? ideally it would be able to be packaged into a .WAR and dropped in the directory and just work. It doesn't seem to work with my installed tomcat server as is because it says the port is already in use. I'm using Ubuntu karmic with the tomcat6 package installed, it could also be my user doesnt have permissions to publish to the running tomcat on 8080 i hope this question is clear enough sample code: @WebService public class UserAttributes { public static void main(String[] args) { UserAttributes instance = new UserAttributes(); Endpoint.publish("http://localhost:8082/WebServices/userattributes", instance); } public string Hello() { return "Hello World"; } }

  • Job queue manager with RPC interface

    - by admr
    I need a job queue manager that I can control over the Internet. It should be able to execute and stop processes, check on their status (ideally notice and execute some code when a process exits), respond to commands and also be able to report back to a server. Background: I have a GWT application that allows to create jobs to execute on a cloud instance (currently EC2). I want to push a "job packet" (data for a process to operate on etc) to S3, start a Linux EC2 instance (or use one that's already running), and tell a job manager on the instance to execute that job (possibly parallel to other jobs). It should then pull the "job packet" from S3, run a process that operates on that data and report back to the server that is running the server part of my GWT application with some information (e.g. exit code, stdout, stderr). If I have to write e.g. stdour/err to a file from the process and read that file, that's OK too. I would really like the manager to be "close" to the processes it runs, meaning I want to avoid using something like Runtime.exec from the JDK. It seems like I would have to do that if I used Quartz for example. I'm fine with the calls in both directions being asynchronous. I'm fine with any reasonable technology for the calls as long as I can easily build an interface for that in my GWT server side (e.g. HTTP requests to a servlet over SSL would be nice and trivial). The job manager does not need to have a very sophisticated queueing system. Running several processes either sequentially or in parallel should be fine. Determining how much compute time a process received during its lifetime would be nice (AFAIK, this might be challenging). I did not yet find any existing software that does this, including http://java-source.net/open-source/job-schedulers. I suspect I might have to build an RPC interface (with authentication etc, of course) around a job manager; maybe use something like Apache Commons Exec. In that case, I would prefer Java or Python for the job manager part. I would be happy to hear suggestions for either the former or latter scenario!

  • DataView.RowFilter an ISO8601

    - by Ryan
    I have a DataTable (instance named: TimeTable) whose DefaultView (instance named: TimeTableView) I am trying to use to filter based on a date. Column clock_in contains an ISO8601 formatted string. I would like to select all the rows in this DataTable/DefaultView between 2009-10-08T08:22:02Z and 2009-10-08T20:22:02Z. What would I have to filter on this criteria? I tried: TimeTableView = TimeTable.DefaultView; TimeTableView.RowFilter = "clock_in >= #2009-10-08T08:22:02Z# and #2009-10-08T20:22:02Z#"; This is not working for me. Am I operating on the wrong object or is my filter syntax wrong?

  • Find workspace location using ANT

    - by ThunderChunky_SF
    I'm working on a build script in the Flash Builder version of Eclipse. This build script needs to import launch configuration .launch files into the user's workspace. However there doesn't seem to be an available ANT var for determining the workspace location. While stepping through the available vars with intellisense I noticed that ${osgi.instance.area} does point to my current workspace but when I tried to echo it back in a running ant script it just spat out "${osgi.instance.area}" and not the path. Any help would be greatly appreciated. Thank you!!!
