• jQuery won't parse my JSON from AJAX query

  - by littlecharva

  Hi, I'm having difficulty parsing some JSON data returned from my server using jQuery.ajax() To perform the AJAX I'm using: $.ajax({ url: myUrl, cache: false, dataType: "json", success: function(data){ ... }, error: function(e, xhr){ ... } }); And if I return an array of items then it works fine: [ { title: "One", key: "1" }, { title: "Two", key: "2" } ] The success function is called and receives the correct object. However, when I'm trying to return a single object: { title: "One", key: "1" } The error function is called and xhr contains 'parsererror'. I've tried wrapping the JSON in parenthesis on the server before sending it down the wire, but it makes no difference. Yet if I paste the content into a string in Javascript and then use the eval() function, it evaluates it perfectly. Any ideas what I'm doing wrong? Anthony

• WCF REST with jQuery AJAX - removing/working around same origin policy

  - by csauve

  So I'm trying to create a C# WCF REST service that is called by jQuery. I've discovered that jQuery requires that AJAX calls are made under the same origin policy. I have a few questions for how I might proceed. I am already aware of; 1. The hacky solution of JSONP with a server callback 2. The way too much server overhead of having a cross-domain proxy. 3. Using Flash in the browser to make the call and setting up crossdomain.xml at my WCF server root. I'd rather not use these because; 1. I don't want to use JSON, or at least I don't want to be restricted to using it 2. I would like to separate the server that serves static pages from the one that serves application state. 3. Flash in this day in age is out of the question. What I'm thinking: is there anything like Flash's crossdomain.xml file that works for jQuery? Is this "same-origin" policy a part of jQuery or is it a restriction in specific browsers? If it's just a part of jQuery, maybe I'll try digging in the code to work around it.

• Find first item inside angular brackets after occurrence of other item, using RegEx, in C#

  - by Mihaela

  I have an xml-like text, in which I would like to find the item that occurs in the first occurrence of a certain pattern: typically: ... <PropertyGroup><name>true</name></PropertyGroup><PropertyGroup>.... .... Could also be ... <PropertyGroup> <name> true</name> </PropertyGroup> ... <PropertyGroup> ... In the above, I need to extract the "name". My initial assumption was that all occurrences were to be in one line, and I wrote my code using string properties, but it is very difficult o take in consideration every possibility, and only RegEx can save me. I just don't know how to write it... I Have started with something like this: Regex regex = new Regex("(?<=<PropertyGroup>#)<+"); Match matches = regex.Matches(Text)[0]; MessageBox.Show(matches.ToString()); I think this finds the first item after a <PropertyGroup>, but I don't know how to make it get the item within the angular brackets... (which may be after one or more newlines, and/or spaces). I know that there are utilities for parsing xml, but I am looking for something simple to insert in a c# program Can someone please help me ? Thank you very much.

• How can I get the Hibernate Configuration object from Spring?

  - by Wayne Russell

  Hi, I am trying to obtain Spring-defined Hibernate Configuration and SessionFactory objects in my non-Spring code. The following is the definition in my applicationContext.xml file: Code: <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop> <prop key="hibernate.show_sql">true</prop> <prop key="hibernate.hbm2ddl.auto">update</prop> <prop key="hibernate.cglib.use_reflection_optimizer">true</prop> <prop key="hibernate.cache.provider_class">org.hibernate.cache.HashtableCacheProvider</prop> </props> </property> <property name="dataSource"> <ref bean="dataSource"/> </property> </bean> If I now call getBean("sessionFactory"), I am returned a $Proxy0 object which appears to be a proxy for the Hibernate SessionFactory object. But that isn't what I want - I need the LocalSessionFactoryBean itself because I need access to the Configuration as well as the SessionFactory. The reason I need the Configuration object is that our framework is able to use Hibernate's dynamic model to automatically insert mappings at runtime; this requires that we change the Configuration and rebuild the SessionFactory. Really, all we're trying to do is obtain the Hibernate config that already exists in Spring so that those of our customers that already have that information in Spring don't need to duplicate it into a hibernate.cfg.xml file in order to use our Hibernate features.

• Scala type conversion error, need help!

  - by Mansoor Ashraf

  Hello I am getting a weird error when trying to use a Java map in Scala. This is the snippet of code val value:Double = map.get(name) if (value eq null) map.put(name, time) else map.put(name, value + time) the map is defined as val map=new ConcurrentHashMap[String,Double] and this is the error I am getting error: type mismatch; found : Double required: ?{val eq: ?} Note that implicit conversions are not applicable because they are ambiguous: both method double2Double in object Predef of type (Double)java.lang.Double and method doubleWrapper in object Predef of type (Double)scala.runtime.RichDouble are possible conversion functions from Double to ?{val eq: ?} if (value eq null) map.put(name, time) I am new to Scala so I am having a hard time parsing the stacktrace. Any help would be appreciated

• Where does Tomcat append / to directory paths?

  - by Anonymouse

  Suppose my Tomcat webapps directory looks like this: webapps/ webapps/fooapp/ webapps/fooapp/WEB-INF/ webapps/fooapp/WEB-INF/web.xml webapps/fooapp/bardir/ When I make a GET request for /fooapp/bardir, Tomcat sees that webapps/fooapp/bardir is a directory and sends back a 302 to /fooapp/bardir/ (with a slash at the end). Here is my question: Where in the Tomcat source code does this take place? (I'm looking at 6.0.x but a correct answer for any version would be a great starting point.) The only reference material I can find on this subject is in the Catalina Functional Specifications which states, regarding the Default Servlet: On each HTTP GET request processed by this servlet, the following processing shall be performed: [...] If the requested resource is a directory: If the request path does not end with "/", redirect to a corresponding path with "/" appended so that relative references in welcome files are resolved correctly. However, this functionality does not appear to be in org.apache.catalina.servlets.DefaultServlet; or at least, it's not there exclusively: if I replace the default servlet in web.xml with a servlet whose servlet-class does not exist, directory paths still come back 302 to add the slash, while every other request comes back with an error as expected.

• Validating Application Settings Key Values in Isolated Storage for Windows Phone Applications

  - by Martin Anderson

  Hello everyone. I am very new at all this c# Windows Phone programming, so this is most probably a dumb question, but I need to know anywho... IsolatedStorageSettings appSettings = IsolatedStorageSettings.ApplicationSettings; if (!appSettings.Contains("isFirstRun")) { firstrunCheckBox.Opacity = 0.5; MessageBox.Show("isFirstRun not found - creating as true"); appSettings.Add("isFirstRun", "true"); appSettings.Save(); firstrunCheckBox.Opacity = 1; firstrunCheckBox.IsChecked = true; } else { if (appSettings["isFirstRun"] == "true") { firstrunCheckBox.Opacity = 1; firstrunCheckBox.IsChecked = true; } else if (appSettings["isFirstRun"] == "false") { firstrunCheckBox.Opacity = 1; firstrunCheckBox.IsChecked = false; } else { firstrunCheckBox.Opacity = 0.5; } } I am trying to firstly check if there is a specific key in my Application Settings Isolated Storage, and then wish to make a CheckBox appear checked or unchecked depending on if the value for that key is "true" or "false". Also I am defaulting the opacity of the checkbox to 0.5 opacity when no action is taken upon it. With the code I have, I get the warnings Possible unintended reference comparison; to get a value comparison, cast the left hand side to type 'string' Can someone tell me what I am doing wrong. I have explored storing data in an Isolated Storage txt file, and that worked, I am now trying Application Settings, and will finally try to download and store an xml file, as well as create and store user settings into an xml file. I want to try understand all the options open to me, and use which ever runs better and quicker

• Remote C++ Development using SSH only inside Eclipse Environment

  - by EFreak

  How do you integrate Remote Systems Explorer and CDT plugin inside eclipse ? What I mean is that you can use Remote Systems Explorer (RSE) plugin to work on C++ code on a remote linux box inside Eclipse but when you try to compile, you basically run a shell command through SSH. The CDT plugin is unable to locate the remote system and off course the remote compiler. Is there a way to integrate both the plugins so that we can use the parsing / suggestion features of CDT for the remote system as well; and also features like remote compilation, remote debugging using SSH only. If this is not possible, then what is the closest open source alternative to the above problem.

I could not understand how it is not permitting to the Admin account to show the reports. Please guide me I am using IIS 6.0 , SQL server2008 R2. I am totally new for the this kind of stuff.

It should not ask for username and password.I know we can do this by IIS , but some how I can not found my SSRS virtual directory. how can i do that ?

• Retrieve input and output parameters for SQL stored procs and functions?

  - by Darth Continent

  For a given SQL stored proc or function, I'm trying to obtain its input and output parameters, where applicable, in a Winforms app I'm creating to browse objects and display their parameters and other attributes. So far I've discovered the SQL system function object_definition, which takes a given sysobjects.id and returns the text of that object; also discovered via search this post which describes extracting the parameters in the context of a app using the ADO.NET method DeriveParameters in conjunction with some caching for better performance; and for good measure found some helpful system stored procs from this earlier post on Hidden Features of SQL Server. I'm leaning towards implementing the DeriveParameters method in my C# app, since parsing the output of object_definition seems messy, and I haven't found a hidden feature in that post so far that would do the trick. Is DeriveParameters applicable to both functions and stored procs for purposes of retreiving their parameters, and if so, could someone please provide an example?

• Convert scientific notation to decimal notation

  - by Ankur

  There is a similar question on SO which suggests using NumberFormat which is what I have done. I am using the parse() method of NumberFormat. public static void main(String[] args) throws ParseException{ DecToTime dtt = new DecToTime(); dtt.decToTime("1.930000000000E+02"); } public void decToTime(String angle) throws ParseException{ DecimalFormat dform = new DecimalFormat(); //ParsePosition pp = new ParsePosition(13); Number angleAsNumber = dform.parse(angle); System.out.println(angleAsNumber); } The result I get is 1.93 I didn't really expect this to work because 1.930000000000E+02 is a pretty unusual looking number, do I have to do some string parsing first to remove the zeros? Or is there a quick and elegant way?

• asn.1 parser in C/Python

  - by elventear

  I am looking for a solution to parse asn.1 spec files and generate a decoder from those. Ideally I would like to work with Python modules, but if nothing is available I would use C/C++ libraries and interface them with Python with the plethora of solutions out there. In the past I have been using pyasn1 and building everything by hand but that has become too unwieldly. I have also looked superficially to libtasn1 and asn1c. The first one had problems parsing even the simplest of files. The second has a good parser but generating C code for decoding seems too complex; the solution worked well with straightforward specs but choked on complex ones. Any other good alternatives I may have overlooked?

• JBoss Developer Studio exploaded SAR/EAR/WAR deployment

  - by dr_hoppa

  I am new to JBoss DS and I could not figur out is how to make a folder from my project deployable, exploded SAR in my case. If I create a new server in the JBoss server view / JBoss AS perspective and select a SAR and make it a deployable then the SAR file can be deployed on the JBoss server. Another approch that I have tryed is to make the *-service.xml file as a deployable element, same procedure as with the SAR file, and to add the Eclipse project as a dependency to the classpath of the server 'Open launch configuration' / 'Classpath' after dooing this I got an error from JBoss telling me that the JBoss classes are not found. The compromise solution that I have found is to create a junction/symlink from the output of the Eclipse project 'bin' into the JBoss 'serve//deploy/xxx.sar' this is a temporary solution but will not scale in the future as multiple services must be created. What I would need: I would need to have the ability to make the exploded folder as 'mark deployable' and to be have the classes/*service.xml files loaded from there and to have hot-deployability for them. Any sugestions would help.

• Inflated ImageView to put in GalleryView isn't the right size

  - by Richard

  I am trying to inflate an ImageView that scales a Drawable that I can display in a GalleryView. My code to inflate the view seems to work fine, except that the attributes of the ImageView are not applied. Specifically, the inflated ImageView does not have the width/height that I set for it via the android:layout params in XML. Can someone show me what I'm doing wrong? I want to set the width/height of the image in dp, so that it is the correct size across multiple screen dpis and support Android 1.5+. As a result I cannot use something like: i.setLayoutParams(new Gallery.LayoutParams(150, 116) My layout definition is: <?xml version="1.0" encoding="utf-8"?> <ImageView xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="150dp" android:layout_height="116dp" android:background="@drawable/gallery_item_background" android:scaleType="fitXY" /> </ImageView> And the snippet I am using to inflate the ImageView is: public View getView(int position, View convertView, ViewGroup parent) { LayoutInflater inflater = getLayoutInflater(); ImageView i = (ImageView) inflater.inflate(R.layout.gallery_item, null); i.setImageResource(mImageIds.get(position)); i.setScaleType(ImageView.ScaleType.FIT_XY); return i; }

The header looks link: - -> http://ext.last.fm/2.0/?api%5Fsig=aa3e9ac9edf46ceb9a673cb76e61fef4&flashresponse=true&y=1269686332&streaming=true&playlistURL=lastfm%3A%2F%2Fplaylist%2Ftrack%2F42620245&fod=true&sk=ee93ae4f438767bf0183d26478610732&lang=de&api%5Fkey=da6ae1e99462ee22e81ac91ed39b43a4&method=playlist%2Efetch GET http://play.last.fm/preview/118270350.mp3 HTTP/1.1 Host: play.last.fm User-Agent: Mozilla/5.0 (X11; U; Linux i686; de; rv:1.9.2) Gecko/20100308 Ubuntu/10.04 (lucid) Firefox/3.6 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: de,en-us;q=0.7,en;q=0.3 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 115 Proxy-Connection: keep-alive Cookie: AnonWSSession=ee93ae4f438767bf0183d26478610732; AnonSession=cb8096e3b0d8ec9f4ffd6497a6d052d9-12bb36d49132e492bb309324d8a4100fc422b3be9c3add15ee90eae3190db5fc localhost - - [27/Mar/2010:11:38:52 CET] "GET http://www.lastfm.de/log/flashclient/minor/Track_Loading_Fail/Buffering_Timeout HTTP/1.1" 404 7593 - -> http://www.lastfm.de/log/flashclient/minor/Track_Loading_Fail/Buffering_Timeout localhost - - [27/Mar/2010:11:38:52 CET] "GET http://play.last.fm/preview/118270350.mp3 HTTP/1.1" 302 0 I nead some hints why or what the communication disturb.

• ImageViews in a ListView not aligned vertically [Mono for Android]

  - by shalmon

  I'm very new to developing apps to android, so bear with me. Having said that, I'm trying to make a list with a image to the left and a title and description to the right of the image. The image is downloaded from the web in the background and then set in the UI as they complete. This all works. However, the images are not aligned properly and I simply cannot understand why. I'm thinking it has something to do with the layout defined in the xml file? I tried using android:layout_alignParentLeft="true" and android:layout_gravity="left" but that got me nowhere. Then I didn't know how to proceed, even after googling every way I could think of. I'm sorry if this is very basic, but I would really appreciate some help here. Here's a pic of the situation: And here's my layout: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/widget28" android:layout_width="fill_parent" android:layout_height="80px" > <ImageView android:id="@+id/imageItem" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_vertical" android:layout_alignParentLeft="true" > </ImageView> <LinearLayout android:id="@+id/linearText" android:layout_width="wrap_content" android:layout_height="fill_parent" android:orientation="vertical" android:layout_marginLeft="10px" android:layout_marginTop="10px" > <TextView android:id="@+id/textTop" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="TextView" > </TextView> <TextView android:id="@+id/textBottom" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="TextView" > </TextView> </LinearLayout> </LinearLayout> I appreciate any help you can offer.
