• Problem of reading OWL/XML

  - by Mikae Combarado

  Hello, I have a problem reading OWL/XML files from Java using Jena. I have no problem reading RDF/XML files, but whenever I create a OWL/XML file from Protege and try to read it, Java gives this error below : WARN [main] (RDFDefaultErrorHandler.java:36) Exception in thread "main" java.lang.NullPointerException at com.hp.hpl.jena.rdf.arp.impl.XMLHandler.endElement(XMLHandler.java:143) The code that I use to retrieve RDF/XML is below : OntModel ontModel = ModelFactory.createOntologyModel(); InputStream in = FileManager.get().open(inputFileName); if (in == null) { throw new IllegalArgumentException( "File: " + inputFileName + " not found"); } ontModel.read(in, ""); This code works with RDF/XML perfectly. However, I cannot read an OWL/XML. I looked at Internet and I couldn't find anything. I would really appreciate, if someone shows me a way. Many thanks

• General rule - when to use a model (Codeigniter)

  - by pingu

  Hi guys, I was just curious as to what the rule of thumb was for models. Generally, I use them only for situations where I need to add/edit or update database entries for an object. However, I'm building an app at the moment that has a "config" table which holds various data, such as last updated, which will control when certain features in the app should be displayed. In this instance, I will mostly need to retrieve data from the config table. Is it worth putting these config methods in model? I'm interested to hear how more experienced coders approach the MVC methodology in CI - example pseudo methods (e.g., what methods relating to the same object you'd use in the model and the controller) would be most helpful.

• Capturing a NSParseErrorException

  - by Martin

  Could someone tell me how I can capture a NSParseErrorException? The Situation: my app downloads a small .plist file. I convert this into dictionary using the string method -propertylist. This normally works fine. I check for a connection before going to retrieve the file, so it works fine if I've got a connection to the internet, and works fine when I don't. However, I discovered a use case that crashes. If I'm at location that requires authetication before connecting to the internet (at Starbucks, say) what's being returned by the app isn't a plist and the attempt to parse it causes the application to crash. So is there a way to transform my code so that the NSParseErrorException is caught and rather than crashing the program I can just skip over this piece of code? NSDictionary *temp = [myDownloadString propertyList]; I tried doing this if ([myDownloadString propertyList]==NSParseErrorException){ //do something } but that didn't work.

• Searching Outlook Global Adress List

  - by MoominTroll

  I'm pulling up the Global Address List from Outlook like so... Microsoft.Office.Interop.Outlook.Application oApp = new Microsoft.Office.Interop.Outlook.Application(); AddressList gal = oApp.Session.GetGlobalAddressList(); ...with the aim of eventually being able to search through this in my own application to retrieve contact information which I can then supply to a method that squirrels off an email. Unfortunately given that my own GAL has about 20K entries in (the customers much more) using a foreach or something simply doesn't work in an acceptable timeframe. I want to pass a string like "Tom" to a method and have it return a list of possible contacts. Is this possible outside of actually opening up Outlook and creating the mail there? Note: There are a couple of other questions similar to this but most seem to have no good answer. I'm hoping I have more luck.

• Recursive FTP directory listing in shell/bash with a single session (using cURL or ftp)

  - by Timo

  I am writing a little shellscript that needs to go through all folders and files on an ftp server (recursively). So far everything works fine using cURL - but it's pretty slow, becuase cURL starts a new session for every command. So for 500 directories, cURL preforms 500 logins. Does anybody know, whether I can stay logged in using cURL (this would be my favourite solution) or how I can use ftp with only one session in a shell script? I know how to execute a set of ftp commands and retrieve the response, but for the recursive listing, it has to be a little more dynamic... Thanks for your help!

• Implementing a configurable factory

  - by Decko

  I'm having difficulties finding out how to implement a 'configurable' behavior in a factory class in PHP. I've got at class, which takes another class as an argument in its constructor. The argument class could take a number of arguments in its constructor. An instance of my main class could look something like this $instance = new MyClass(new OtherClass(20, true)); $instance2 = new MyClass(new DifferentClass('test')); This is rather clumsy and has a number of problems and therefore I would like to move this into a factory class. The problem is that this factory somehow needs to know how to instantiate the argument class, as this class can have any number of arguments in the constructor. Preferably I would like to be able to do something like this $instance = Factory::build('OtherClass'); $instance2 = Factory::build('DifferentClass'); And let the factory retrieve the arguments from a configuration array or similar. Is there a proper solution to this problem?

• Changing the config file in a Visual Studio Package

  - by Andrei

  Hello everybody. I'm building a Visual Studio Package and associated with it, I have an app.config file (which contains some information about connecting to a WCF service). As far as I can tell, this package is actually connecting to the devnev.exe.config configuration file (if I use AppDomain.CurrentDomain.SetupInformation.ConfigurationFile), it will retrieve the path to the devnev.exe.config Firstly, is this correct? Shouldn't the package automatically pick up the app.config file? If this is the case, then how can I make the project use the app.config file? I'm running VS2010 Ultimate, programming in C#. Thanks!

• SQL Server join and wildcards

  - by Ernst

  I want to get the results of a left join between two tables, with both having a column of the same name, the column on which I join. The following query is seen as valid by the import/export wizard in SQL Server, but it always gives an error. I have some more conditions, so the size wouldn't be too much. We're using SQL Server 2000 iirc and since we're using an externally developed program to interact with the database (except for some information we can't retrieve that way), we can not simply change the column name. SELECT table1.*, table2.* FROM table1 LEFT JOIN table2 ON table1.samename = table2.samename At least, I think the column name is the problem, or am I doing something else wrong?

• C# Exception when retrieving rows from a datagrid in virtual mode

  - by JamesM

  Hi all, I keep getting an exception (see below) when I retrieve a list of rows from a Virtual Mode datagrid, this only happens when I have more rows than I can display on screen and it doesn't happen every time. Is there anything I'm missing with regards to virtual mode? Update The image below shows the problem, the index is now outside the list range. The reason for this is say I have 10 items and I hide 5 as they are not needed and I want to run some code on the 5 that are visible, there are now 5 items but the index of some maybe between 5-9, how can I re-index? When I have run some code on the visible 5 I then show the hidden 5 so I don't want to disgard these, I'd need to reindex again when they are all visible. Many thanks.

• Legality, terms of service for performing a web crawl

  - by Berlin Brown

  I was going to crawl a site for some research I was collecting. But, apparently the terms of service is quite clear on the topic. Is it illegal to now "follow" the terms of service. And what can the site normally do? Here is an example clause in the TOS. Also, what about sites that don't provide this particular clause. Restrictions: "use any robot, spider, site search application, or other automated device, process or means to access, retrieve, scrape, or index the site" It is just research? Edit: "OK, from the standpoint of designing an efficient crawler. Should I provide some form of natural language engine to read terms of service and then abide by them."

• Which thread invokes SensorEventListener.onSensorChanged

  - by Christoph Heindl

  From my records it seems that SensorEventListener.onSensorChanged callback is called by the same thread that registered the callback. I.e there must be some message-queue synchronization going on in the background which allows the activitys UI-Thread to handle the callbacks. That leads to my question: Is there a need to synchronize SensorEventListener.onSensorChanged with the activitys UI-thread, assuming that the activitys UI-thread registered the SensorEventListener? I cannot find any documentation references, but can see various examples calling invalidate() unsychronized or synchronize the entire callback. I used something along the lines of Log.i(TAG, "" + Thread.currentThread().getId()); to retrieve threading information. I'm running android 2.1 update1. Best regards, Christoph

• What is the most stupid coded solution you have read/improved/witnessed?

  - by Rigo Vides

  And for stupid I mean Illogical, non-effective, complex(the bad way), ugly code style. I will start: We had a requirement there when we needed to hide certain objects given the press of a button. So this framework we were using at the time provided a way to tag objects and retrieve all the objects with a certain tag in a complete iterable collection. So I presented the most logically solution given these conditions to my partner: Me: you know, tag all the objects we needed to hide with the same tag, then call the function to get them all, iterate trough them and make them hidden. Partner: I don't know, that is hardcoding for me... Me: So what do you suggest? 20 mins later... Partner: I don't know... let's put a tag to all the objects to be hidden like this, 1, 2, 3, 4, 5, 6, 7 (and so for each object to be hidden), Then we make a for from 1 to n (where n was the number of objects to hide) and we hide them all there!

• How to select difference using sql?

  - by ganuke

  I wrote a sql query to retrieve data as follows: SELECT (MAX (b.filledqty) - MAX (a.filledqty)) AS filledtoday FROM clientordermas a, clientordermas b WHERE a.clordid = 'w9110126' AND b.clordid = 'w9110126' AND (SELECT max(a.price) FROM clientordermas a WHERE a.clordid = 'w9110126') < 1000; There are three records in the table for the given clordid with price values 800, 900 1200. So, what I need is to get the difference between 1200 and 900 which is 300. But, the above statement always returns 0. What I should get is MAX (b.filledqty) retuns 1200 and MAX (a.filledqty) retuns 900. But it is not happening. This is not the exact problem I am facing but a simplified version of it. Can someone please help?

• CodeIgniter - Post multiple arrays to controller

  - by Bobe

  I have a dynamically generated form that allows users to enter new data and edit existing data. When the form is submitted, it collates the input values and groups them according to whether they are new or not, the former being denoted by class="new-entry". So the function generates two arrays: updateData and insertData. Both arrays are of similar formats: [ 0: { 'id' = 1, 'value' = foo }, 1: { 'id' = 1, 'value' = 'bar' }, etc... ] I am combining them into a new array object to send via ajax to the controller: var postData = { 'update_data': updateData, 'insert_data': insertData }; Then in the ajax call: $.post(url, postData, function() { // some code }); However, in the controller, doing print_r($this->input->post()) or print_r($_POST) as a test only returns Array(). Even $this->input->post('update_data') returns nothing. How can I retrieve these arrays in the controller?

• 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.

• MOSS Collect Data from user custom email

  - by nav

  Hi, I am trying to send out a custom email, after the Collect Data from user step in my primary workflow which starts when an item in list X is created. I have created a secondary workflow to start when a new Task item is created (this is created by the Collect Data from user action in the primary workflow). But I am having problem how I retrieve the information on the list X. I know the ID of the referenced item in List X is stored in a URL within the "Link" column in the Tasks lists. But can't see any string manipulation function that will grab this ID so I can use it to link back to relevant item in List X. Is there an easier way to do this? Many Thanks, Nav

• English dictionary as txt or xml file with support of synonyms

  - by Simon

  Can someone point me to where I can download English dictionary as a txt or xml file. I am building a simple app for myself and looking for something what I could start using immediately without learning complex API. Support for synonyms would be great, that is it should be easier to retrieve all the synonyms for particular word. It would be absolutely fantastic if dictionary would be listing British and American spelling of the words where they are differ. Even if it would be small dictionary (few 000's words) that's ok, I only need it for small project. I even would be willing to buy one if the price is reasonable, and dictionary is easy to use - simple xml wold be great. Any directions please.

• Tool to Verify Site URLs/SiteMap?

  - by LockeCJ

  I'm moving a site from one e-commerce software to another, and I've created URL Rewriter rules to do 301 redirects from the Old URLs to the new ones. I've tested them with a small sample of URLs, but I'm looking for some sort of tool that will let me test as many of the URLs as possible. Does anyone know of a tool that I can feed a list of URLs (or a sitemap.xml). This tool will attempt to retrieve each URL, and then report the status code for each. The result should be a list of URLs with the status code, something like this: www.site.com/oldurlformat1/ 301 Permanently Moved www.site.com/newurlformat1/ 200 OK www.site.com/oldurlformat2/ 301 Permanently Moved www.site.com/newurlformat2/ 200 OK I can almost do this with wget, but getting the summary/report at the end is where I'm stuck.

  I am building a web application in which I would like to include the user's LinkedIn profile page feeds. Is this possible? What I envision is the user comes to the web application and adds the complete URL for their Linked user profile in a text box and I would get the feeds for that user page. Would it be possible to do this with jquery? Or should I be looking at some other tool? I trying to make it more clear, I want to create a widget kinda of app for my web app where user enters a complete url of the linkedin user profile page and I have to retrieve the feeds of that particular user and display it. It should be dynamic in nature, if another user enters a another url into the text box I should be able to get the feeds from that particular user profile page.

• Retrieving the type of a Collection

  - by nevets1219

  So I have something like the following in Java: private List<SomeType>variable; // ....variable is instantiated as so ... variable = new ArrayList<SomeType>(); // there's also a getter public List<SomeType> getVariable() { /* code */ } What I would like to be able to do is figure out that variable is a collection of SomeType programmatically. I read here that I can determine that from the method getVariable() but is there any way to tell directly from variable? I have been able to retrieve SomeType from the getter method based on the information in the link. I have also been successful in retrieving all the fields of the surrounding class via SurroundingClass.getClass().getDeclaredFields() but this doesn't tell me that it is List<SomeType>.
