• NSIS takes ownership of IIS system files

  - by Lucas

  I recently encountered an issue with NSIS that I believe is related to an interaction with UAC, but I am at a loss to explain it and I do not know how to prevent it in the future. I have an installer that creates and removes IIS virtual directories using the NsisIIS plugin. The installer appeared worked correctly on my Windows 7 workstation. When the installer was run on a Windows 2008 R2 server it installed properly, but the uninstaller removed all of the virtual directories and put IIS is an unusable state; to the point that I had to remove the Default Web Site and re-add it. What I eventually found was that all of the IIS configuration files under C:\Windows\System32\inetsrv\config had a lock icon on them. Some investigation seem to indicate that this means a user account has taken ownership of the file, however all the files listed SYSTEM as the file owner. I did check a different server that I have not run the installer on, and it does not have the lock icon applied to the IIS files. I have also seen the same lock icon appear on other files that the NSIS installer creates. For instance, I have a Web.Config.tpl file that is processed using the NSIS ReplaceInFile which also appears with the lock icon after the installer finished. After I explicitly grant another user account access to the file, the lock icon goes away. I run the installer under the local Administrator account on the 2008 R2 server, so I do not get the UAC prompt. Here is the relevant code from the install.nsi file RequestExecutionLevel admin Section "Application" APP_SECTION SectionIn RO Call InstallApp SectionEnd Section "un.Uninstaller Section" Delete "$PROGRAMFILES\${PROGRAMFILESDIR}\Uninstall.exe" Call un.InstallApp SectionEnd Function InstallApp File /oname=Web.Config Web.Config.tpl !insertmacro ReplaceInFile Web.Config %CONNECTION_STRING% $CONNECTION_STRING FunctionEnd Function un.InstallApp ReadRegStr $0 HKLM "Software\${REGKEY}" "VirtualDir" NsisIIS::DeleteVDir "$0" Pop $0 FunctionEnd I have three questions stemming from this incident: How did this happen? How can I fix my installer to prevent it from happening again? How can I repair the permissions on the IIS config files.

• VS2010 / Target Framework = 3.5 / Building on Continuous Integration Server

  - by granadaCoder

  I'm checking into upgrading to VS2010. Our production servers only have 3.5 Framework and it will be 6-9 months before they are updated. We also have a Continuous Integration Server, running CruiseControl.NET (CC.NET). It has the 3.5 Framework on it as well. Our implementation of CC.NET mainly calls msbuild.exe MySolution.msbuild. (We encapsulate most of the build logic into .msbuild files fyi) Inside the .msbuild file, the following is the "Build" syntax: < Target Name="Build" DependsOnTargets="Checkout" < MSBuild Projects="$(WorkingCheckout)\MySolution.sln" Targets="Build" Properties="Configuration=$(Configuration)" < Output TaskParameter="TargetOutputs" ItemName="TargetOutputsItemName"< /Output < /MSBuild < /Target (A few spaces added to make it display here) =========== I know the VS2010 can "Target" the 3.5 Framework. My question is what happens when I have a VS2010 dev machine, and I check the VS2010 .sln and .csproj(s) files into source control (svn, btw).....will the CC.NET machine ~~which only have the 3.5 Framework installed on it........be able to build the .sln ? I guess I could test it, but the catch22 is that I don't have VS2010 (yet). So I'm asking before I try (the trial or a real install. ............. Any ideas what will happen? I guess the crux question is, what will happen. c:\WINDOWS\Microsoft.NET\Framework\v3.5\MSBuild.exe "MyVS2010SolutionFile.sln" ?? My hopeful goal would be, allow the developers to have VS2010 (now!), and it still be "ok" for the CC.NET machine and the Production Servers which will only have the 3.5 Framework on them for the foreseeable future. Just to be clear, developers NEVER create deployable builds. Only the CC.NET machine produces builds that will be pushed as production builds. Any help?

• PHP DOM vs SimpleXML for Atom GData feed parsing

  - by Geoff Adams

  I'm building a library to access the Google Analytics Data Export API. All the data the library accesses is in Atom format and utilises numerous different namespaces throughout. My experiments with the API have used SimpleXML for parsing so far, especially as all I have been doing is accessing the data held within the feed. Now I'm coming to write a library I am wondering whether forging ahead with SimpleXML will be adequate or whether the enhanced functionality of the DOM module in PHP would be of benefit in the future. I haven't written much code for this part of the library yet so the choice is still open. I have read that the PHP DOM module can be a better choice if you need to build an XML DOM on the fly or modify an existing one, but I'm not entirely sure I would need that functionality anyway due to the nature of the API (no pushing data to the server, for instance). SimpleXML is certainly easier to use and I have seen people saying that for read-only situations it is all you need. Essentially the question is, what would you use? Compatibility will not be an issue as the server configuration will match the application's requirements. Is it worth building the library with PHP DOM in mind or should I stick with SimpleXML for now? Update: Here are two examples of the kind of feeds I will be dealing with: Account feed Data feed

• Getting started with character and text processing (encoding, regular expressions)

  - by TK

  I'd like to learn foundations of encodings, characters and text. Understanding these is important for dealing with a large set of text whether that are log files or text source for building algorithms for collective intelligence. My current knowledge is pretty basic: something like "As long as I use UTF-8, I'm okay." I don't say I need to learn about advanced topics right away. But I need to know: Bit and bytes level knowledge of encodings. Characters and alphabets not used in English. Multi-byte encodings. (I understand some Chinese and Japanese. And parsing them is important.) Regular expressions. Algorithm for text processing. Parsing natural languages. I also need an understanding of mathematics and corpus linguistics. The current and future web (semantic, intelligent, real-time web) needs processing, parsing and analyzing large text. I'm looking for some resources (maybe books?) that get me started with some of the bullets. (I find many helpful discussion on regular expressions here on Stack Overflow. So, you don't need to suggest resources on that topic.)

• Where should I declare my CDI resources?

  - by Laird Nelson

  JSR-299 (CDI) introduces the (unfortunately named) concept of a resource: http://docs.jboss.org/weld/reference/1.0.0/en-US/html/resources.html#d0e4373 You can think of a resource in this nomenclature as a bridge between the Java EE 6 brand of dependency injection (@EJB, @Resource, @PersistenceContext and the like) and CDI's brand of dependency injection. The general gist seems to be that somewhere (and this will be the root of my question) you declare what amounts to a bridge class: it contains fields annotated both with Java EE's @EJB or @PersistenceContext or @Resource annotations and with CDI's @Produces annotations. The net effect is that Java EE 6 injects a persistence context, say, where it's called for, and CDI recognizes that injected PersistenceContext as a source for future injections down the line (handled by @Inject). My question is: what is the community's consensus--or is there one--on: what this bridge class should be named where this bridge class should live whether it's best to localize all this stuff into one class or make several of them ...? Left to my own devices, I was thinking of declaring a single class called CDIResources and using that as the One True Place to link Java EE's DI with CDI's DI. Many examples do something similar, but I'm not clear on whether they're "just" examples or whether that's a good way to do it. Thanks.

• LaTeX: bibliography per chapter.

  - by YuppieNetworking

  Hello all, I am helping a colleague with his PhD thesis and we need to present the bibliography at the end of each chapter. The question is: does anyone have a minimal working example for this case using latex+bibtex? The current document structure that we use is the following: main.tex chap1.tex chap2.tex ... chapn.tex biblio.bib Where main.tex contains packages, document declarations, macros and \includes for each chapter. biblio.bib is the only bibtex file (I think is easier to have all citations in one place). We have searched and tried with different latex packages, reading and following their documentation. Specifically, bibitems and chapterbib. bibitems successfully generates bu*.aux files, but when running bibtex for each one of them, an error occurs since there is no \bibdata element in the .aux file. chapterbib also generates a .aux file, but bibtex finishes with an error caused by using multiple \bibliography{file} in the .tex files (one per chapter). Some coworkers suggested using a separate bibtex file for each chapter, which could be a problem of maintenance in the future when citing the same publications in different chapters. We will like to continue having this document structure, if possible. So, if anyone could shed some light to this problem, we will appreciate it. Thanks.

• .NET Reference "Copy Local" True / Fasle Being Set Based on Contents of General Assembly

  - by D-Sect

  Hello All. First question for me here. We had a very interesting problem with a Win Forms project. It's been resolved. We know what happened, but we want to understand why it happened. This may help other people out in the future who have a similar problem. The WinForms project failed on 2 of our client's PCs. The error was an obscure kernel.dll error. The project ran fine on 3 other PCs. We found that a .DLL (log4net.dll - a very popular open-source logging library) was missing from our release folder. It was previously in our release folder. Why was it missing in this latest release? It was missing because I must have installed a program on my Dev box that used log4net.dll and it was added to the general assembly. When I checked the SLN's references for log4net.dll, they were changed to "copy local=FALSE". They must have changed automagicially because log4net.dll was present in my GAC. Here's where my question starts: Why did my reference for log4net.dll get changed from COPY LOCAL = TRUE to COPY LOCAL = FALSE? I suspect it's because it was added to my GAC by another program. How can we prevent this from happening again? As it stands now, if I install a piece of software that uses a common library and it adds it to my GAC, then my SLNs that REF that DLL will change from Copy Local TRUE to FALSE. Thank you so much. I hope this helps people out who have a piece of software that runs in some places, but not in others, when it used to run fine in ALL places.

• Mark duplicates in MySql with php (without deleting)

  - by Adam

  So, I'm having some problems with a MySQL query (see other question), and decided to try a different approach. I have a database table with some duplicate rows, which I actually might need for future reference, so I don't want to remove. What I'm looking for is a way to display the data without those duplicates, but without removing them. I can't use a simple select query (as described in the other question). So what I need to do is write a code that does the following: 1. Go through my db Table. 2. Spot duplicates in the "ip" column. 3. Mark the first instance of each duplicate with "0" (in a column named "duplicate") and the rest with "1". This way I can later SELECT only the rows WHERE duplicate=0. NOTE: If your solution is related to the SELECT query, please read this other question first - there's a reason I'm not just using GROUP BY / DISTINCT. Thanks in advance.

• Is there something like a "long running offline transaction" for NHibernate or any other ORM?

  - by Vilx-

  In essence this is a followup of this question. I'm beginning to feel that I should give up the whole idea, but I'll give it one more shot. What I want is pretty much like a DB transaction. It should track my changes to the DB and then in the end allow me to either commit or rollback them. If I insert an object, I should get it back in my next (appropriate) SELECT query. If I delete it, future SELECT queries should not return it. Etc. But there is one catch - this transaction would be very long running. It would start when the user opened a form (I'm talking about Windows Forms here), and the commit/rollback would be when the user closed it(with OK/Cancel). So it could take anywhere between seconds and days. This requirement rules out a standard DB transaction because that would lock the tables/rows it touched, and other users wouldn't be able to use the system. Also the transaction should not commit ANY changes to the DB until it was really committed. So if one user makes some changes, others don't see them until OK button is hit. This prevents errors in case the computer crashes or is disconnected from the network. I'm quite OK if the solution puts constraints on my model (I'm using MSSQL 2008, btw). I can design the DB/code any way I like. I'm also fine with the idea that a commit could fail because someone already modified one of the objects my transaction touched. Is there anything like this? I looked at NHibernate.Burrow, but I'm not sure that that's the thing I want. Added: It's the very beginning of the project so I'm not tied to NHibernate. I started out with it but I can still change easily.

• How important is PhD research topic to getting a job?

  - by thornate

  EDIT: This has been closed and I realise that I may not have been specific enough with the original title. I ask two questions here: The general one (Does a PhD help get a job?) which has been asked elsewhere, and the specific one (Is it possible to get work outside of the specific research field?). Assume I've already decided going to do the phd. I'm just stressing about the research topic. Well, I'm one year out of university (Mechatronics engineering and Software Eng double bachelors), worked for a few months then got retrenched (yay economy!). It's looking less and less likely that I'll get a job worth having with the job market as it is, so I'm thinking about going back to uni to do a PhD. I figure that by the time I'm done, the job market will have improved and hopefully I'll have something on my resume that is more attractive than spending three years doing customer support for accounting software. So, my question is to people who've done PhD's. Would you say that they were worth the effort? How important is the research topic to future job-seeking success? The idea I have is a computer-sciencey/neural-networks/data-mining thing which I think is very interesting, but not a field I want to be in forever. My potential supervisor claims that employers don't care so much about the topic of the research but rather the peripheral skills that are developed through a PhD; time managment, self-restraint, planning and whatnot. How does this mesh with people's real world experience? I'd appreciate any advice before signing my life on the line for the next three years. See also: Should developers go to grad school?

• Modeling a Generic Relationship in a Database

  - by StevenH

  This is most likely one for all you sexy DBAs out there: How would I effieciently model a relational database whereby I have a field in an "Event" table which defines a "SportType". This "SportsType" field can hold a link to different sports tables E.g. "FootballEvent", "RubgyEvent", "CricketEvent" and "F1 Event". Each of these Sports tables have different fields specific to that sport. My goal is to be able to genericly add sports types in the future as required, yet hold sport specific event data (fields) as part of my Event Entity. Is it possible to use an ORM such as NHibernate / Entity framework which would reflect such a relationship? I have thrown together a quick C# example to express my intent at a higher level: public class Event<T> where T : new() { public T Fields { get; set; } public Event() { EventType = new T(); } } public class FootballEvent { public Team CompetitorA { get; set; } public Team CompetitorB { get; set; } } public class TennisEvent { public Player CompetitorA { get; set; } public Player CompetitorB { get; set; } } public class F1RacingEvent { public List<Player> Drivers { get; set; } public List<Team> Teams { get; set; } } public class Team { public IEnumerable<Player> Squad { get; set; } } public class Player { public string Name { get; set; } public DateTime DOB { get; set;} }

• Java RMI InitialContext: Equivalent of LocateRegistry.createRegistry(int) ?

  - by bguiz

  I am trying to some pretty basic RMI: // Context namingContext = new InitialContext(); Registry reg = LocateRegistry.createRegistry(9999); for ( int i = 0; i < objs.length; i++ ) { int id = objs[i].getID(); // namingContext.bind( "rmi:CustomObj" + id , objs[i] ); reg.bind( "CustomObj" + id , objs[i] ); } That works without a hitch, but for future purposes, I need to use InitialContext. Context namingContext = new InitialContext(); for ( int i = 0; i < objs.length; i++ ) { int id = objs[i].getID(); namingContext.bind( "rmi:CustomObj" + id , objs[i] ); } But I cannot get this to work. I have started rmiregistry from the command line. Is there an equivalent of LocateRegistry.createRegistry(int)? Or some other way to start the RMI registry / registry used by InitialContext from inside my class? (Instead of the command line) Stack trace: javax.naming.CommunicationException [Root exception is java.rmi.ServerException: RemoteException occurred in server thread; nested exception is: java.rmi.UnmarshalException: error unmarshalling arguments; nested exception is: java.lang.ClassNotFoundException: bguiz.scratch.network.eg.Student] at com.sun.jndi.rmi.registry.RegistryContext.bind(RegistryContext.java:126) at com.sun.jndi.toolkit.url.GenericURLContext.bind(GenericURLContext.java:208) at javax.naming.InitialContext.bind(InitialContext.java:400) at bguiz.scratch.RMITest.main(RMITest.java:29) Caused by: java.rmi.ServerException: RemoteException occurred in server thread; nested exception is: java.rmi.UnmarshalException: error unmarshalling arguments; nested exception is: java.lang.ClassNotFoundException: bguiz.scratch.CustomObj at sun.rmi.server.UnicastServerRef.oldDispatch(UnicastServerRef.java:396) at sun.rmi.server.UnicastServerRef.dispatch(UnicastServerRef.java:250) ....(truncated) EDIT: I will delete my own question in a couple of days, as there seems to be no answer to this (I haven't been able to figure it out myself).

• To (monkey)patch or not to (monkey)patch, that is the question

  - by gsakkis

  I was talking to a colleague about one rather unexpected/undesired behavior of some package we use. Although there is an easy fix (or at least workaround) on our end without any apparent side effect, he strongly suggested extending the relevant code by hard patching it and posting the patch upstream, hopefully to be accepted at some point in the future. In fact we maintain patches against specific versions of several packages that are applied automatically on each new build. The main argument is that this is the right thing to do, as opposed to an "ugly" workaround or a fragile monkey patch. On the other hand, I favor practicality over purity and my general rule of thumb is that "no patch" "monkey patch" "hard patch", at least for anything other than a (critical) bug fix. So I'm wondering if there is a consensus on when it's better to (hard) patch, monkey patch or just try to work around a third party package that doesn't do exactly what one would like. Does it have mainly to do with the reason for the patch (e.g. fixing a bug, modifying behavior, adding missing feature), the given package (size, complexity, maturity, developer responsiveness), something else or there are no general rules and one should decide on a case-by-case basis ?

• Spell checker software

  - by Naren

  Hello Guys, I have been assigned a task to find a decent spell checker (UK English) preferably the free one for a project that we are doing. I have looked at Google AJAX API for this. The project contains some young person's (kids less than 18 years old) data which shouldn't allow exposing or storing outside the application boundaries. Google logs the data for research purpose that means Google owns the data whatever we send over the wire through Google API. Is this right? I fired an email to Google regarding the privacy of data and storage but they haven't come back. If you have some knowledge regarding this please share with me. At this point our servers might not have access to external entities that means we might not be able to use Web API for this over the wire. But it may change in the future. That means I have to find out some spell checker alternatives that can sit in our environment and do the job or an external APIs. Would you mind share your findings and knowledge in this regard. I would prefer free services but never know if you have some cracking spell checker for a few quid’s then I don't mind recommending to the project board. Technology using ASP.NET 3.5/4.0, MVC, jQuery, SQL Sever 2008 etc Cheers, Naren

• Composite key syntax in Boost MultiIndex

  - by Sarah

  Even after studying the examples, I'm having trouble figuring out how to extract ranges using a composite key on a MultiIndex container. typedef multi_index_container< boost::shared_ptr< Host >, indexed_by< hashed_unique< const_mem_fun<Host,int,&Host::getID> >, // ID index ordered_non_unique< const_mem_fun<Host,int,&Host::getAgeInY> >, // Age index ordered_non_unique< const_mem_fun<Host,int,&Host::getHousehold> >, // Household index ordered_non_unique< // Age & eligibility status index composite_key< Host, const_mem_fun<Host,int,&Host::getAgeInY>, const_mem_fun<Host,bool,&Host::isPaired> > > > // end indexed_by > HostContainer; My goal is to get an iterator pointing to the first of the subset of elements in HostContainer hmap that has age partnerAge and returns false to Host::isPaired(): std::pair< hmap::iterator,hmap::iterator > pit = hmap.equal_range(boost::make_tuple( partnerAge, false ) ); I think this is very wrong. How/Where do I specify the iterator index (which should be 3 for age & eligibility)? I will include other composite keys in the future. What exactly are the two iterators in std::pair? (I'm copying syntax from an example that I don't understand.) I would ideally use std::count to calculate the number of elements of age partnerAge that are eligible (return false to Host::isPaired()). What is the syntax for extracting the sorted index that meets these requirements? I'm obviously still learning C++ syntax. Thanks in advance for any help.

• Things one needs to know while writing a game engine

  - by Joe Barr

  I have been dabbling in game development as a hobby for a while now, and I cannot seam to quite get my games to sparkle at least a bit with some graphics. I have decided to write a simple test game engine that only focuses on the representation of graphics - shapes, textures and surfaces. While I have a few very simple game engines designed for my own games under my belt, I want to create a game engine that I can use to display and play with graphics. I'm going to do this in C++. Since this is my first time with a major engine, the engine in not going to focus on 3D graphics, it's going to be a mixture of isometric and 2D graphics. My previous engines have incorporated (been able to draw) or focused on simple flat (almost 2D) non impressive graphic designs and representations of: the player NPCs objects walls and surfaces textures Also, I had some basic AI and sometimes even sound. They also saved and loaded games. They didn't have a map editor or a level editor. Is this going to be a problem in the future? At this time I have to point out that some of my games didn't get finished because I was to lazy to write the few last levels. My question at this point would be: What are some things one should know if one wants write (develope) a better graphical game engine with all it's functions.

• Type error while trying to implement the (>>=) function in order to create a custom monad transforme

  - by CharlieP

  Hello, I'm trying to create a monad transformer for a future project, but unfortunately, my implementation of the Monad typeclasse's (=) function doesn't work. First of all, here is the underlying monad's implementation : newtype Runtime a = R { unR :: State EInfo a } deriving (Monad) Here, the implementation of the Monad typeclasse is done automatically by GHC (using the GeneralizedNewtypeDeriving language pragma). The monad transformer is defined as so : newtype RuntimeT m a = RuntimeT { runRuntimeT :: m (Runtime a) } The problem comes from the way I instanciate the (=) function of the Monad typeclasse : instance (Monad m) => Monad (RuntimeT m) where return a = RuntimeT $ (return . return) a x >>= f = runRuntimeT x >>= id >>= f The way I see it, the first >>= runs in the underlying m monad. Thus, runRuntimeT x >>= returns a value of type Runtime a (right ?). Then, the following code, id >>=, should return a value of type a. This value is the passed on to the function f of type f :: (Monad m) => a -> RuntimeT m b. And here comes the type problem : the f function's type doesn't match the type required by the (=) function. Jow can I make this coherent ? I can see why this doesn't work, but I can't manage to turn it into something functionnal. Thank you for you help, and do not hesitate to correct any flaws in my message, Charlie P.

• Question about SQL Server HierarchyID depth-first performance

  I am trying to implement hierarchyID in a table (dbo.[Message]) containing roughly 50,000 rows (will grow substantially in the future). However it takes 30-40 seconds to retrieve about 25 results. The root node is a filler in order to provide uniqueness, therefor every subsequent row is a child of that dummy row. I need to be able to traverse the table depth-first and have made the hierarchyID column (dbo.[Message].MessageID) the clustering primary key, have also added a computed smallint (dbo.[Message].Hierarchy) which stores the level of the node. Usage: A .Net application passes through a hierarchyID value into the database and I want to be able to retrieve all (if any) children AND parents of that node (besides the root, as it is filler). A simplified version of the query I am using: @MessageID hierarchyID /* passed in from application */ SELECT m.MessageID, m.MessageComment FROM dbo.[Message] as m WHERE m.Messageid.IsDescendantOf(@MessageID.GetAncestor((@MessageID.GetLevel()-1))) = 1 ORDER BY m.MessageID From what I understand, the index should be detected automatically without a hint. From searching forums I have seen people utilizing index hints, at least in the case of breadth-first indexes, as apparently CLR calls may be opaque to the query optimizer. I have spent the past few days trying to find a solution for this issue, but to no avail. I would greatly appreciate any assistance, and as this is my first post, I apologize in advance if this would be considered a 'noobish' question, I have read the MS documentation and searched countless forums, but have not came across a succinct description of the specific issue.

• XmlSerializer equivalent of IExtensibleDataObject

  - by demoncodemonkey

  With DataContracts you can derive from IExtensibleDataObject to allow round-tripping to work without losing any unknown additional data from your XML file. I can't use DataContract because I need to control the formatting of the output XML. But I also need to be able to read a future version of the XML file in the old version of the app, without losing any of the data from the XML file. e.g. XML v1: <Person> <Name>Fred</Name> </Person> XML v2: <Person> <Name>Fred</Name> <Age>42</Age> </Person> If reading an XML v2 file from v1 of my app, deserializing and serializing it again turns it into an XML v1 file. i.e. the "Age" field is erased. Is there anything similar to IExtensibleDataObject that I can use with XmlSerializer to avoid the Age field disappearing?

• 3D Web Sites and Applications

  - by Scott Evernden

  I have for the last several years been struggling to understand why the Internet has so few actually useful 3D web applications. It's 2009 and still everything looks like pages from a Sears catalog. You can turn on your TV and find flying logos every night. After that you can get nostalgic and flip on ol' N-64 and play some Zelda or Mario Kart. On the PC, Sims 2 is approaching 6 years old already.. And then there's WoW. Current generation of users - the Facebook crowd, let's say - has ~no~ problem dealing with multi-dimensional environments.. And yet, nothing really immersive seems to happen on the web. I've been hearing about VRML and X3D for at least 10 years and ... pffft .. - nothing earth shaking going on there. Java 3D ? .. cool ! .. but ...... Still .... waiting and waiting. Do you think it will take a killer-web app before people become accustomed-to or will seek to use what could more more engaging web experiences? I am not talking about Second Life and other dedicated downloaded applications. I probably am more focused on apps like Lively or SceneCaster or Hangout or a half dozen others that are delivered 'painlessly' directly into web pages. My own particular interest is in the domain of virtual stores and immersive shopping. Its been a challenge trying to understand why an average user would not want to browse and wander a changing mall-space - like in the real world -- entertained by unexpected discovery. Is the 3D web always going to be 5 years in the future ?

• Selecting a Java framework for large application w/ only ONE user

  - by Bijan

  I am building a large application that will be hosted on an AWS server. I'm trying to select a web framework for assisting me with code organization, template design, and generally presentation aspects. Here are some points of consideration: Require security/login/user authentication. I may add the ability in the future to allow more than just an administrator to access the web app, but it is not a public facing website. AJAX support would be helpful. There are a couple widgets that I don't want to recreate. One is a tree object, where the user can expand/contract items in the list, can create new branches, add/edit objects. This would be better off in some dynamic view rather than all done in ugly html. Generally, this is just to provide the application with a face for control, management, and monitoring. Having an easier time adding buttons, CSS, AJAX widgets are great additions though, but not the primary purpose. I'm considering: Wicket Spring Seam GWT Stripe and the list goes on, as I'm sure you all know. I originally planned on using GWT, but then started to feel that GWT didn't cover my primary needs. I could be wrong about this, but there seems to be a lot of support for GWT AND Wicket/Spring. All of this 'getting lost in java frameworks' got me thinking outside the java realm for a framework that would suit my needs that was a clear option, like: JRuby/Rails Jython/Django Groovy/Grails Guice (just throwing this in there... I don't clearly understand the main purposes of all these frameworks. It doesn't seem like DInjection is something I need for a single purpose application) Thanks as always. This community makes Googling for esoteric programming information an order of magnitude better.

• Zendx JQuery Autocomplete

  - by emeraldjava

  I've been trying to get the Zend Jquery autocomplete function working, when i noticed this section in the Zend documentation. The following UI widgets are available as form view helpers. Make sure you use the correct version of jQuery UI library to be able to use them. The Google CDN only offers jQuery UI up to version 1.5.2. Some other components are only available from jQuery UI SVN, since they have been removed from the announced 1.6 release. autoComplete($id, $value, $params, $attribs): The AutoComplete View helper will be included in a future jQuery UI version (currently only via jQuery SVN) and creates a text field and registeres it to have auto complete functionality. The completion data source has to be given as jQuery related parameters 'url' or 'data' as described in the jQuery UI manual. Does anybody know which svn url tag or branch i need to download to get a javascript file with the autocomplete functions available in it? At the moment, my Bootstrap.php has $view->addHelperPath('ZendX/JQuery/View/Helper/', 'ZendX_JQuery_View_Helper'); $view->jQuery()->enable(); $view->jQuery()->uiEnable(); Zend_Controller_Action_HelperBroker::addHelper( new ZendX_JQuery_Controller_Action_Helper_AutoComplete() ); // Add it to the ViewRenderer $viewRenderer = new Zend_Controller_Action_Helper_ViewRenderer(); $viewRenderer->setView($view); Zend_Controller_Action_HelperBroker::addHelper($viewRenderer); In my layout, i define the jquery ui version i want <?php echo $this->jQuery() ->setUiVersion('1.7.2');?> Finally my index.phtml has the autocomplete widget <p><?php $data = array('New York', 'Tokyo', 'Berlin', 'London', 'Sydney', 'Bern', 'Boston', 'Baltimore'); ?> <?php echo $this->autocomplete("ac1", "", array('data' => $data));?></p> I'm using Zend 1.8.3 atm.

• WCF Double Hop questions about Security and Binding.

  - by Ken Maglio

  Background information: .Net Website which calls a service (aka external service) facade on an app server in the DMZ. This external service then calls the internal service which is on our internal app server. From there that internal service calls a stored procedure (Linq to SQL Classes), and passes the serialized data back though to the external service, and from there back to the website. We've done this so any communication goes through an external layer (our external app server) and allows interoperability; we access our data just like our clients consuming our services. We've gotten to the point in our development where we have completed the system and it all works, the double hop acts as it should. However now we are working on securing the entire process. We are looking at using TransportWithMessageCredentials. We want to have WS2007HttpBinding for the external for interoperability, but then netTCPBinding for the bridge through the firewall for security and speed. Questions: If we choose WS2007HttpBinding as the external services binding, and netTCPBinding for the internal service is this possible? I know WS-* supports this as does netTCP, however do they play nice when passing credential information like user/pass? If we go to Kerberos, will this impact anything? We may want to do impersonation in the future. If you can when you answer post any reference links about why you're answering the way you are, that would be very helpful to us. Thanks!
