JiBX binding DTD schema in Eclipse

- by Trick

I have warnings in binding xml files: No grammar constraints (DTD or XML schema) detected for the document. I have done as is written in the answer here: http://stackoverflow.com/questions/982263/jibx-how-do-i-keep-using-interfaces-in-my-code (answer which is not accepted). But now I have an error in binding xml file: Referenced file contains errors (file:/C:/Amplio/LiveCliq/Work/core/src/main/resources/config/rest/ mappings/binding.dtd). For more information, right click on the message in the Problems View and select "Show Details..." And the details are: The markup in the document preceding the root element must be well-formed. line 20 I am not familiar with DTD schemas, so I don't know what is the problem. Did anybody found the solution? And - I do not want to turn off validation in XML files, I would like to have this in binding files (mainly for code assist and validation).

Performance benefits of upgrading Richfaces to newer version

- by peteDog

I have a client that's running an application based on JBoss 4.0.5, Seam 1.2 and RichFaces 3.0.1. Their system is having performance problems due to the fact that a lot of data is coming back from the server to be displayed on screen and it seems like the rendering of that data is taking forever. The data brought back is displayed in a tabbed interface, but the tabs aren't currently being loaded individually, but all at once. I'm trying to build up a case to present to the client on the benefits of upgrading to never version of RichFaces, which, as I understand it, has added a great number of features related to tabbed panels and being able to use ajax to page the data and load the chunks you actually need to display at the moment, and not the rest that's in other tabs. The move to a newer version of RichFaces will also result in never versions of Jboss and Seam, as the current production build of RichFaces 3.2.1 requires JSF 1.2. IF anyone has some suggestions or experience on performance of current versions RichFaces, paging, etc, I would really appreciate some feedback.

Is there a Maven plugin to generate AS3 classes from Java for BlazeDS ?

- by Maskime

Hi, I'm looking for a maven plugin that would generate ActionScript3 classes from Java classes in order to access them by object remoting. I've seen FlexMojo but it uses the GraniteDS generator wich create some problems when it comes to map Enum objects (wich can be fix through a workaround that is describe here : http://dev.c-ware.de/confluence/display/PUBLIC/Flexmojos+generated+AS3+model+with+Enum+support+using+BlazeDS?focusedCommentId=7634946&#comment-7634946 if you've googled your way here this might be useful) when working with BlazeDS. Everything that i found so far are people who explain how to generate VO classes on flex side using Flash Builder 4, but this solution can not be used in an industrial developpement environnement. Thanks in advance for any leads on this matter.

ASP.Net Count Download Clicks

- by Marco

Hello, I thought that this was easier… I have a asp:hyperlink control, with target=”_blank”, pointing to the file I want the user to download. My plan is to track the number of times, the users click on this link. I thought in placing it in ajax update panel, to catch the postback and avoid full page refresh. However, hyperlink doesn’t have a onClick method. On the other hand I could use a linkbutton, which has a onClick built in. But It’s harder to make the file open in a new window… and I would also have to do something like: Response.AppendHeader("Content-Disposition","attachment; filename=myImage.jpg"); But I heard that the above approach has some problems with PPT, PPTX, PPS, PPSX… What is you'r opinion on this? How and why, would you do it?

Libqxt under Qt Creator

- by I'm Dario

I want to create a tiny app which needs global shortcuts. So, I have downloaded the current version of libqxt (0.5.1) and opened as a project in Qt Creator. Libqxt compiles without problems in this way, so I thought that adding this in the tab Dependencies of my project it would get added automatically in the build, like Eclipse does with JAR libraries (I know that are different IDEs but it seems to be a common feature among them). What happens? Qt Creator compiles qxt before my project, when needed, but when I want to include its headers Qt Creator keeps warning me that it cannot find them. Probably I am missing the correct name of headers (I tried the headers showed in qxt documentation: http://doc.libqxt.org/0.5.0/classQxtGlobalShortcut.html) By the way, I looked the code for global shortcuts and I think I can rip it out and use it in my app as is and I am going to credit qxt team and open the code of my app.

WIX: COM unregistration when removing one of two programs

- by madbadger

Hello, I am relatively new to WiX. It is a great tool, but I still need some time to learn it better. I have encountered a problem with registration and unregistration of a COM component. I have created installers for two applications, lets call them A and B. Both are using the same COM component. I have used the heat tool, as recommended. When installing A or B, the component is registered without any problems. But when I install A and B, then remove A (with Add/Remove programs) the COM class gets unregistered and B cannot use it anymore. Is there a clean solution to prevent this from happening? I would like to unregister the COM when BOTH A and B are uninstalled. Any help would be appreciated, Best regards, madbadger

Serverside image processing

- by spol

I am designing a web application that does server side image processing in real time. Processing tasks include applying different effects like grayscale, blur, oil paint, pencil sketch etc on images in various formats. I want to build it using java/servlets which I am already familiar with. I found 3 options, 1) Use pure java imaging libraries like java.awt or http://www.jhlabs.com/ip/index.html 2) Use command line tools like Gimp/ImageMagick 3) Use c,c++ image libraries that have java bindings. I don't know which of the above options is good keeping the performance in mind. It looks like option 2) and 3) are good performance wise, but I want to be sure before I rule out 1). I have also heard gimp cannot be run using command line unless gtk or xwindows is already installed on the server. Will there be any such problems with 2) or 3) while running them server side? Also please suggest any good image processing libraries for this purpose.

daynamic 2d array in c++ and memory leaks

32-bit oracle 10g client to 64-bit oracle 10g server

- by Dakshin

Due to a 3rd party application's requirement, I may be forced to use 32-bit client of Oracle 10gR2 on the application server to connect to a 64-bit DB server oracle 10gR2 (10.2.0.4.0 - 64bit;another box). The OS is SUSE Linux ver 10. Platform is x86. There are no problems connecting to 64-bit DB server via 32-bit client. I have tested this. Does this result in performance degradation? Does Oracle or anyone else has any recommendations about this kind of scenario? Searched the net without much gain. Please help. Thanks.

Leak - GeneralBlock-3584

- by lamicka

When i try to check leaks of my iPhone App using Instruments, everything is just fine. Same App on actual real device shows this leak for a few times during the app launch. It is pretty non-deterministic and it happens in system libraries. I tried to google down the solution without a luck. Anyone experiencing the same problems? Anyone knows the solution? I find interesting, that every of my leak in code will crash the app sooner or later. These GeneralBlock-3584 leaks keeps app perfectly stable. Might this be reason for AppStore rejection? Thanx for any answer regarding this undocumented problem (Apple is silent unfortunately).

LinkedList cannot be serialised?

- by iTayb

Here are my classes: http://pastebin.com/3dc5Vb1t When I try to run BookStore b = new BookStore(); b.LoadFromXML(Server.MapPath("list.xml")); Label1.Text = b.ToString(); I get the following error: You must implement a default accessor on System.Collections.Generic.LinkedList`1[[Book, App_Code.cxsacizw, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null]] because it inherits from ICollection. The error source is XmlSerializer s = new XmlSerializer(typeof(BookStore)); When I tried to look for a solution on google, I found it that LinkedList has some problems with serialization. How can I deal with it? Thank you very much.

Using mergedModelFromBundles: and versioning (CoreData)

- by charlax

Hi everybody, I'm trying to use the migration feature in CoreData. I've followed the Apple Documentation. I have a problem in the following method: /** Returns the managed object model for the application. If the model doesn't already exist, it is created by merging all of the models found in the application bundle. */ - (NSManagedObjectModel *)managedObjectModel { if (managedObjectModel != nil) { return managedObjectModel; } /* * NSInvalidArgumentException', reason: '*** -[NSCFArray insertObject:atIndex:]: attempt to insert nil' * 2010-02-17 16:27:15.338 Patrimoine[3037:207] */ managedObjectModel = [[NSManagedObjectModel mergedModelFromBundles:nil] retain]; return managedObjectModel; } It appears that there is the same problem on http://iphonedevelopment.blogspot.com/2009/09/core-data-migration-problems.html Yet I did choose the method Apple suggests, by using the menu option "Add Model Version". Do you have any idea?

Tweepy + App Engine Example OAuth Help

- by Wasauce

Hi I am trying to follow the Tweepy App Engine OAuth Example app in my app but am running into trouble. Here is a link to the tweepy example code: http://github.com/joshthecoder/tweepy-examples Specifically look at: http://github.com/joshthecoder/tweepy-examples/blob/master/appengine/oauth_example/handlers.py Here is the relevant snippet of my code [Ignore the spacing problems]: try: authurl = auth.get_authorization_url() request_token = auth.request_token db_user.token_key = request_token.key db_user.token_secret = request_token.secret db_user.put() except tweepy.TweepError, e: # Failed to get a request token self.generate('error.html', { 'error': e, }) return self.generate('signup.html', { 'authurl': authurl, 'request_token': request_token, 'request_token.key': request_token.key, 'request_token.secret': request_token.secret, }) As you can see my code is very similar to the example. However, when I compare the version of the request_token.key and request_token.secret that are rendered on my signup page (this is for the request_token.key and request_token.secret found in the datastore.

Adjusting sql statement in a function based upon input

- by Stefan

Hey there, This is a bit urgent! I'm trying to make a simple filter search where-by you can choose from a series of 3 drop downs and then based upon this the results are then displayed, How would I go about adjusting the sql query for each and if you were to only choose to search from aone of the 3 rather than all 3 etc... example there could be the url with input such as: url.com?location=gb&color=3&hair=4 and still form the correct sql query for something like this: url.com?location=gb&hair=1 and not encounter problems with WHERE and AND etc etc and empty variables in the statement Would this not need to be a massive function to check using if to see how the data is set for all possibilities? Thanks, Stefan

jquery $.ajax to php problem

- by Pouya

hi.i have two problems with jquery $.ajax. first problem is ihave a php file named action.php and here the code: if($_GET['action']=='add'){ //rest of the code here } And i use jquery $.Ajax function to call that when form fills: $.ajax({type:"POST", url:"action.php?action=add", data:$("#form").serialize(), cache:false, timeout:10000}); this works but i wanted to know is there anyway to send the action=add code with data and not the url? and the second problem that i have is that i have a link: <a href="#" onclick="delete(4);">delete row from mysql where id is 4</a> and a jquery function: function deleteUser(id){ $.ajax({type:"POST", url:"action.php?action=delete", data:"id="+id, cache:false, timeout:10000});} and of course the action.php code: if($_GET['action']=='deletestudent'){ mysql_query("DELETE FROM `students` WHERE `student_id` = {$_POST['id']}"); } but it doesn't work.what should i do?

Pagination For SMS in Android specifically

- by Priyank

Hi. I had a pagination related question posted earlier. Here I went through the posted answers and suggested choices and I realized that to implement pagination in an application I could still write db level queries and ensure that I could implement pagination, even if in a crude form. However I have few follow up questions now: I am trying to show SMS from a content provider. Suppose I don't want to use content provider; can I access SMS table in database through my application. Aoes android's security framework allow that? How do people generally handle pagination problems in android, related to content that they are not storing but instead are fetching through content providers. (Android's own or custom) Isn't this a bigger problem. I am surprised to find so little text online about it.

Algorithm to determine thread "hotness"

- by nickf

I'm trying to come up with a way to determine how "hot" certain threads are in a forum. What criteria would you use and why? How would these come together to give a hotness score? The criteria I'm thinking of include: how many replies how long since the last reply average time between replies The problems this algorithm must solve: A thread which has 500 replies is clearly hot, unless the last reply was over a year ago. A thread with 500 replies that was replied to a second ago is clearly hot, unless it's taken 4 years to reach 500 replies. A thread with 15 replies in the last 4 minutes is really hot! Any ideas, thoughts or complete solutions out there?

Can't resolve "UnauthorizedAccessException" with MVC 2 application running under IIS7

- by Daniel Crenna

We use MVC controllers that access System.File.IO in our application and they work fine in localhost (IIS 6.0-based Cassini). Deploying to IIS7, we have problems getting the controllers to work because they throw UnauthorizedAccessExceptions. We have done the following to try to resolve the issue: - Set NETWORK SERVICE and IUSR accounts to have permission on the files and folders in question - Ensured the App Pool is running under NETWORK SERVICE and loading the user profile - Application is running under full trust - We tried adding impersonation to web.config and giving NETWORK SERVICE write permissions Now, we alternate between getting UnauthorizedAccessException and an IIS7 404 page that suggests the routes are being ignored completely (for example we serve "/favicon.ico" via a controller when the physical file actually lives at /content/images/favicon.ico). We used ProcessMonitor to try to track down the issue but weren't successful.

'schema' design for a social network

- by Alan B

I'm working on a proof of concept app for a twitter style social network with about 500k users. I'm unsure of how best to design the 'schema' should I embed a user's subscriptions or have a separate 'subscriptions' collection and use db references? If I embed, I still have to perform a query to get all of a user's followers. e.g. Given the following user: { "username" : "alan", "photo": "123.jpg", "subscriptions" : [ {"username" : "john", "status" : "accepted"}, {"username" : "paul", "status" : "pending"} ] } to find all of alan's subscribers, I'd have to run something like this: db.users.find({'subscriptions.username' : 'alan'}); from a performance point of view, is that any worse or better than having a separate subscriptions collection? also, when displaying a list of subscriptions/subscribers, I am currently having problems with n+1 because the subscription document tells me the username of the target user but not other attributes I may need such as the profile photo. Are there any recommended practices for such situations? thanks Alan

Normalize FFT magnitude to imitate WMP

- by Bevin

So, I've been working on a little visualizer for sound files, just for fun. I basically wanted to imitate the "Scope" and "Ocean Mist" visualizers in Windows Media Player. Scope was easy enough, but I'm having problems with Ocean Mist. I'm pretty sure that it is some kind of frequency spectrum, but when I do an FFT on my waveform data, I'm not getting the data that corresponds to what Ocean Mist displays. The spectrum actually looks correct, so I knew there was nothing wrong with the FFT. I'm assuming that the visualizer runs the spectrum through some kind of filter, but I have no idea what it might be. Any ideas?

Looking for a reporting tool that will allow vector graphics in output file (PDF)

- by Richard West

I have been tasked with evaluating our current system that we use for creating and outputing reports. Currently we are using Crystal Reports ver 8, (I know that this is and old version.), which has a custom commandline app that we wrote in C# to execute the report for a given parameter passed through the command line. We like Crystal becuase it's easy to setup and design the report. It's also easy to print and create a PDF file from crystal using our custom commandline program. One of the problems/complaints that we have is that Crystal does does not appear to have a method that will allow us to create a PDF file with a vector images, such as our company logo. Crystal Reports always converts an image into a bitmap. When the PDF is printed, the results are less than flattering, and the PDF file size is increased. Does anyone have any recomendadtions for a reporting product that we should consider?

Datacontracts property getter running twice

- by user321426

I have a set of data contracts that act as wrappers to base classes that we wish to expose. A quick example is: [DataMember] public List<decimal> Points { get { return sourceObject.ListPoints(); } private set{} } We have some other properties that we have to massage the data first (we are converting object graphs and need to guard against circular references). The issue that we are seeing is that this getter will fire twice, once within the service operation, then again during serialization. This is causing two problems: We manually add to collections, since this is running twice the collections are filled with dupes. If an exception is thrown during the second run, it happens outside of the try/catch in the operation, and does not throw a fault. The service throws a cryptic timeout message, and the only way to see the error is via WCF trace logs.

Is gwt-graphics 0.9.3 compatible with gwt 2.0.3

- by sprasad12

Hi, I am using gwt graphics(vaadin) for one of my project, till yesterday i had gwt1.7.1 and all the drawing objects were working fine. For some reason i had to install eclipse again and so now i have gwt 2.0.3. I am observing few problems with graphics now, like the text is not getting positioned properly, if i do any changes to the code, concerned to drawing objects, it is not showing up. Therefore wanted to know whether gwt-graphics0.9.3 was compatible with gwt 2.0. Thank you.

I'm having some problems with this piece of code. I've included a class declaration and trying to create an object of that class but my code dies out. It doesn't seem to be an include issue as all the files are being included even the files called for inclusion within the class file itself. However the object is not created - I tried to put an echo statement in the __construct function but nothing it just doesn't run infact doesn't create the object and the code won't continue from there - plus no error is reported or displayed and I have error reporting set to E_ALL and display errors set to true WHats happening here :(
