• iis7 compress dynamic content from custom handler

  - by Malloc

  I am having trouble getting dynamic content coming from a custom handler to be compressed by IIS 7. Our handler spits out json data (Content-Type: application/json; charset=utf-8) and responds to url that looks like: domain.com/example.mal/OperationName?Param1=Val1&Param2=Val2 In IIS 6, all we had to do was put the edit the MetaBase.xml and in the IIsCompressionScheme element make sure that the HcScriptFileExtensions attribute had the custom extension 'mal' included in it. Static and Dynamic compression is turned out at the server and website level. I can confirm that normal .aspx pages are compressed correctly. The only content I cannot have compressed is the content coming from the custom handler. I have tried the following configs with no success: <handlers> <add name="MyJsonService" verb="GET,POST" path="*.mal" type="Library.Web.HttpHandlers.MyJsonServiceHandlerFactory, Library.Web" /> </handlers> <httpCompression> <dynamicTypes> <add mimeType="application/json" enabled="true" /> </dynamicTypes> </httpCompression> _ <httpCompression> <dynamicTypes> <add mimeType="application/*" enabled="true" /> </dynamicTypes> </httpCompression> _ <staticContent> <mimeMap fileExtension=".mal" mimeType="application/json" /> </staticContent> <httpCompression> <dynamicTypes> <add mimeType="application/*" enabled="true" /> </dynamicTypes> </httpCompression> Thanks in advance for the help.

• Use Java exceptions internally for REST API user errors?

  - by user303396

  We have a REST API that works great. We're refactoring and deciding how to internally handle errors by the users of our API. For example the user needs to specify the "movie" url parameter which should take the value of "1984", "Crash", or "Avatar". First we check to see if it has a valid value. What would be the best approach if the movie parameter is invalid? return null from one of the internal methods and check for the null in the main API call method throw an exception from the internal method and catch exceptions in the main API method I think it would make our code more readable and elegant to use exceptions. However, we're reluctant because we'd be potentially throwing many exceptions because of user API input errors, our code could be perfect. This doesn't seem to be the proper use of exceptions. If there are heavy performance penalties with exceptions, which would make sense with stack traces needing to be collected, etc., then we're unnecessarily spending resources when all we need to do is tell the user the parameter is wrong. These are REST API methods, so we're not propogating the exceptions to the users of the API, nor would we want to even if possible. So what's the best practice here? Use ugly nulls or use java's exception mechanism?

• Django Class Views and Reverse Urls

  - by kalhartt

  I have a good many class based views that use reverse(name, args) to find urls and pass this to templates. However, the problem is class based views must be instantiated before urlpatterns can be defined. This means the class is instantiated while urlpatterns is empty leading to reverse throwing errors. I've been working around this by passing lambda: reverse(name, args) to my templates but surely there is a better solution. As a simple example the following fails with exception: ImproperlyConfigured at xxxx The included urlconf mysite.urls doesn't have any patterns in it mysite.urls from mysite.views import MyClassView urlpatterns = patterns('', url(r'^$' MyClassView.as_view(), name='home') ) views.py class MyClassView(View): def get(self, request): home_url = reverse('home') return render_to_response('home.html', {'home_url':home_url}, context_instance=RequestContext(request)) home.html <p><a href={{ home_url }}>Home</a></p> I'm currently working around the problem by forcing reverse to run on template rendering by changing views.py to class MyClassView(View): def get(self, request): home_url = lambda: reverse('home') return render_to_response('home.html', {'home_url':home_url}, context_instance=RequestContext(request)) and it works, but this is really ugly and surely there is a better way. So is there a way to use reverse in class based views but avoid the cyclic dependency of urlpatterns requiring view requiring reverse requiring urlpatterns...

• JQuery Simplemodal and Tabs Help Needed

  - by Dave R

  Hi, I've got an asp.net page containing a Textbox with an Autocomplete extender on it. It's setup so the user can type a short reference code into the textbox and then choose from the list of matching codes returned by the autocomplete. On the "select", I then call the server using JQuery. I'm currently using $.get here.... The callback function from $.get checks for "success" and then displays a simple-modal dialog containing info about the item they've just selected. if (sStatus == "success") { $.modal(sText, { overlayClose: true, appendTo:'form', onShow: function(dialog) { $("#ccTargets_tabContainer").tabs(); }, onClose: function(dialog) { $("#<%=TextBox1.ClientID%>").val(""); $.modal.close(); } }); $.ready(); } One of the bits of info being loaded here is a JQuery TABS setup, so the onShow function of the simplemodal is used to initiate the tabs which are within the simplemodal. Now to the crux of my problem. If I do multiple consecutive "autocompletes" on the same page it all works fine Unless I have selected a different tab on the tabs in the simplemodal ....If I select a different tab, close the simplemodal and then do another autocomplete I get a JQuery error which seems to relate to a selector doing something with the "old" selected tab that was on the "closed" modal. I'm clearly missing some sort of cleardown / initialisation somewhere, but can't find what it is. Help? I've tried "tabs.destroy" before the modal call in the code above and I've tried a $.ready() call as indicated too.... UPDATE: Is it something to do with JQuery Tabs appending my addressbar URL with the selected tab's ID?

• Help with redirection for .com, .net and .org domains: redirecting all of them to .com.

  - by user198553

  Hi all! I need help with some rules in ISAPI_Rewrite in my installation. (If you only know mod_rewrite could be a good help to, so I would adapt the configuration). I'm going to be very honest about my needs. I need to do this configuration in the next few hours, and don't have time right now understand everything about rewrites, regular expressions and such. I really think you can help me, if I had more reputation I would even set up a bounty... :( In fact, I believe that what I need is simple: I have a .com domain. The main url of my website is going to be http:// www.mainurl.com/. I have two other domains: mainurl.net and mainurl.org. What I need (in isapi-rewrite 2, the config made with httpd.ini file in root file) is: everytime someone writes mainurl.net in browser it becomes http:// www.mainurl.com/ 301 redirect. If it's written without www becomes http:// www.mainurl.com/. If someone writes mainurl.net/about it becomes http:// www.mainurl.com/about/. Redirect always the .com, the www part and the final slash /. Thanks in advance you all!

• Remote JMS connection still using localhost

  - by James

  I have a created a JMS Connection Factory on a remote glassfish server and want to use that server from a java client app on my local machine. I have the following configuration to get the context and connection factory: Properties env = new Properties(); env.setProperty("java.naming.factory.initial", "com.sun.enterprise.naming.SerialInitContextFactory"); env.setProperty("java.naming.factory.url.pkgs", "com.sun.enterprise.naming"); env.setProperty("java.naming.factory.state", "com.sun.corba.ee.impl.presentation.rmi.JNDIStateFactoryImpl"); env.setProperty("org.omg.CORBA.ORBInitialHost", JMS_SERVER_NAME); env.setProperty("org.omg.CORBA.ORBInitialPort", "3700"); initialContext = new InitialContext(env); TopicConnectionFactory topicConnectionFactory = (TopicConnectionFactory) initialContext.lookup("jms/MyConnectionFactory"); topicConnection = topicConnectionFactory.createTopicConnection(); topicConnection.start(); This seems to work and when I delete the ConnectionFactory from the glassfish server I get a exception indicating that is can't find jms/MyConnectionFactory as expected. However when I subsequently use my topicConnection to get a topic it tries to connect to localhost:7676 (this fails as I am not running glassfish locally). If I dynamically create a topic: TopicSession pubSession = topicConnection.createTopicSession(false, Session.AUTO_ACKNOWLEDGE); Topic topic = pubSession.createTopic(topicName); TopicPublisher publisher = pubSession.createPublisher(topic); Message mapMessage = pubSession.createTextMessage(message); publisher.publish(mapMessage); and the glassfish server is not running locally I get the same connection refused however, if I start my local glassfish server the topics are created locally and I can see them in the glassfish admin console. In case you ask I do not have jms/MyConnectionFactory on my local glassfish instance, it is only available on the remote server. I can't see what I am doing wrong here and why it is trying to use localhost at all. Any ideas? Cheers, James

  I'm trying to follow the kitten example given here http://www.sencha.com/blog/dive-into-dataview-with-sencha-touch-2-beta-2#comment_form and I have complex components in which one of the property of my data is a list of objects. And I do find a method for setting a list of objects which is setItems however it does not seem to work. My object array is my model MyApp.Model.Sponsor. Could anyone suggest what I'm missing to get this working? Ext.define('MyListItem', { extend: 'Ext.dataview.component.DataItem', requires: ['Ext.Button','Ext.Img', 'MyApp.model.Sponsors', 'MyApp.model.Sponsor'], xtype: 'mylistitem', config: { sponsor: true, dataMap: { getSponsor: { setItems: 'sponsor' } } }, applySponsor: function(config) { // I put an alert here to see if I get getSponsor() but the object I get here is undefined alert(this.getSponsor()); return Ext.factory(config, MyApp.model.Sponsor, this.getSponsor()); }, updateSponsor: function(newNameButton, oldNameButton) { if (oldNameButton) { this.remove(oldNameButton); } if (newNameButton) { this.add(newNameButton); } }, onSponsorTap: function(button, e) { var sponsors = record.get('sponsor'); //my specific action } }); Ext.define('MyApp.model.Sponsors', { extend: 'Ext.data.Model', xtype:'Sponsors_m', config: { fields: [ {name: 'level', type: 'auto'}, {name: 'id', type: 'int'}, {name: 'sponsor', type: 'Sponsor'} ] } }); Ext.define('MyApp.model.Sponsor', { extend: 'Ext.data.Model', xtype:'Sponsor_m', config: { fields: [ {name: 'name', type: 'auto'}, {name: 'image', type: 'auto'}, {name: 'url', type: 'auto'}, {name: 'description', type: 'auto'} ] } });

• Authlogic, logout and credential capture

  - by Paddy

  Ok this is something weird. I got authlogic-oid installed in my rails app today. Everything works perfectly fine but for one small nuisance. This is what i did: I first register with my google openid. Successful login, redirection and my email, along with my correct openid is stored in my database. I am happy that everything worked fine! Now when i logout, my rails app as usual destroys the session and redirects me back to my root url where i can login again. Now if i try to login it still remembers my last login id. Not a big issue as i can always "Sign in as a different user" but i am wondering if there is anyway to not only logout from my app but also logout from google. I noticed the same with stack overflow's openid authentication system. Why am i so bothered about this, you may ask. But is it not a bad idea if your web apps end user, who happens to be in a cyber cafe, thinks he has logged out from your app and hence from his google account only to realize later that his google account had got hacked by some unworthy loser who just happened to notice that the one before had not logged out from google and say.. changed his password!! Should i be paranoid?

• Use Maven to trigger a wsgen & wsimport in a row, using wsdlLocation

  - by ben

  I have hard times using maven to generate my client. So Please refer to http://stackoverflow.com/questions/2131001/creating-a-web-service-client-directly-from-the-source for the first part of my question. To keep it simple and short, I want to go from here (a file in src/main/java) : package com.example.maven.jaxws.helloservice; import javax.jws.WebService; @WebService public class Hello { public String sayHello(String param) { ; return "Hello " + param; } } to there : /** * This class was generated by the JAX-WS RI. * JAX-WS RI 2.1.7-b01- * Generated source version: 2.1 * */ @WebServiceClient(name = "HelloService", targetNamespace = "http://helloservice.jaxws.maven.example.com/", wsdlLocation = "http://localhost:8080/test/") public class HelloService extends Service { private final static URL HELLOSERVICE_WSDL_LOCATION; private final static Logger logger = Logger.getLogger(com.example.wsimport.HelloService.class.getName()); ...etc using only 1 pom.xml file. Please note the wsdlLocation set on the end. The pom.xml file will probably use both maven-jaxws-plugin wsgen AND wsimport with some tricky configuration to achieve this.

• Login to website using PHP and get text from page

  - by Anthony Garand

  I am trying to login to a website and grab content from a page you must be authenticated to see. I have done some research and have seen some examples using both cURL and stream_context_create but I cannot get either way to work. I have the url for the page to login to, and the page that contains the data I need to get. Your help is much appreciated! Here's what I'm working with: <?php $pages = array('home' => 'https://www.53.com/wps/portal/personal', 'login' => 'https://www.53.com/wps/portal/personal', 'data' => 'https://www.53.com/servlet/efsonline/index.html?Messages.SortedBy=DATE,REVERSE'); $ch = curl_init(); //Set options for curl session $options = array(CURLOPT_USERAGENT => 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)', CURLOPT_SSL_VERIFYPEER => FALSE, CURLOPT_SSL_VERIFYHOST => 2, CURLOPT_HEADER => TRUE, //CURLOPT_RETURNTRANSFER => TRUE, CURLOPT_COOKIEFILE => 'cookie.txt', CURLOPT_COOKIEJAR => 'cookies.txt'); //Hit home page for session cookie $options[CURLOPT_URL] = $pages['home']; curl_setopt_array($ch, $options); curl_exec($ch); //Login $options[CURLOPT_URL] = $pages['login']; $options[CURLOPT_POST] = TRUE; $options[CURLOPT_POSTFIELDS] = 'uid-input=xxx&pw=xxx'; $options[CURLOPT_FOLLOWLOCATION] = FALSE; curl_setopt_array($ch, $options); curl_exec($ch); //Hit data page $options[CURLOPT_URL] = $pages['data']; curl_setopt_array($ch, $options); $data = curl_exec($ch); //Output data echo $data; //Close curl session curl_close($ch); ?> Cheers, Anthony

• jQuery AJAX call not working in Webkit

  - by Brian

  I've run into a strange issue with Webkit based browsers (both Safari and Chrome - I'm testing on a Mac) and I am not sure what is causing it. Here's a small script I've created that replicates the issue: <html> <head> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <script type="text/javascript" language="javascript"> function doRequest() { document.test.submit(); $.ajax({ type: "GET", cache: false, url: 'ajax.php?tmp=1', success: doSuccess }); } function doSuccess(t_data,t_status,req) { alert('Data is: '+ t_data +', XMLHTTPRequest status is: '+ req.status); } </script> </head> <body> <form name="test" method="post" action="ajax.html" enctype="multipart/form-data"> <input type="file" name="file_1"> <br><input type="button" value="upload" onclick="doRequest();"> </form> </body> </html> ajax.php is: <?php echo $_REQUEST['tmp']; ?> This works as is on Firefox, but the XMLHTTPRequest status is always "0" on both Safari and Chrome. If I remove this line: document.test.submit(); then it works, but of course the form is not submitted. I've tried changing the form submit button from "button" to "submit", but that also prevents it from working on Safari or Chrome. What I am trying to accomplish is: submit the form call another script to get status on the file being uploaded via the form (it's for a small upload progress meter). Any help is really appreciated - I'm hopeful it is just a quirk I'm not familiar with. Thanks! Brian

• Objective-C object release and allocation timing

  - by ryanjm.mp

  The code for this question is too long to be of any use. But I'm pretty sure my problem has to do with releasing a class. I have a helper class, ConnectionHelper.h/.m, that handles a NSURLConnection for me. Basically, I give it the URL I want and it returns the data (it happens to do a quick json parse on it too). It has a delegate which I set to the calling class (in this case: DownloadViewController). When it finishes the download, it calls [delegate didFinishParseOf:objectName withDictionary:dictionary];. Then in DownloadViewController I release ConnectionHelper and alloc a new one in order to download the next object. My problem is, I do this once, and then it creates the connection for the second one, and then my program just crashes. After this call: [[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookieAcceptPolicy:NSHTTPCookieAcceptPolicyNever]; NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; Then I don't think any of the following methods are called: - (NSCachedURLResponse *)connection:(NSURLConnection *)connection willCacheResponse:(NSCachedURLResponse *)cachedResponse - (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response - (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data - (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error - (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge So am I right in that I'm not releasing something? When I release it the first time, the dealloc function isn't being called. Is there a way I can "force" it to deallocate? Do I need to force it to? I didn't think it would matter since I allocating a new ConnectionHelper for the new call. How else would they overlap / conflict with each other? Thank you.

• Using JSON with jRails

  - by Zachary

  I am currently trying to use AJAX in my application via jRails. I am trying to return a JSON object from my controller, and then parse it in my Javascript. I am using json2.js to do the parsing. Here is the code I currently have: function getSomething() { $.ajax({ type: "GET", url: "map/testjson", success: function(data) { var myData = JSON.parse(data[0]); window.alert(myData.login); } }); } and in the controller: class Map::MapController < ApplicationController def index end def testjson @message = User.find(:all) ActiveRecord::Base.include_root_in_json = false respond_to do |w| w.json { render :json => @message.to_json } end end end The window.alert simply says 'undefined' (without tics). However, if I change the javascript to window.alert(data) (the raw object returned by the controller) I get: [{"salt":"aSalt","name":"", "created_at":"2010-03-15T02:34:25Z","remember_token_expires_at": null,"crypted_password":"aPassword", "updated_at":"2010-03-15T02:34:25Z","id":1,"remember_token":null, "login":"zgwrig2","email":"[email protected]"}] This looks like an array of size 1, if I'm looking at it correctly, but I have tried just about every combination of JSON.parse on the data object that I can think of, and nothing seems to work. Any ideas on what I'm doing wrong here?

• Rotate a feature Image in Open Layers - ReApply StyleMap to layer.

  - by Ozaki

  I have an open layers map. It adds and removes my "imageFeature" every 10secs or so. I have a JSON feed that gives me the rotation that I need, I have a request to get that rotation and set it as a variable of rotationv. Everything works but the fact when the image is recreated it does not update the rotation. My code is as follows: JSON request: var rotationv = (function () { rotationv = null; $.ajax({ 'async': false, 'global': true, 'url': urldefault, 'dataType': "json", 'success': function (data) { rotationv = data.rotation; } }); return rotationv })(); Creating image feature: imageFeature = new OpenLayers.Feature.Vector( new OpenLayers.Geometry.Point(mylon, mylat), { rotation: rotationv } ); The image is set in the styling elsewhere. Why does this not rotate my image? Debugging with firebug I now notice that "rotationv" is updating as per it should be. But when the point is destroyed then added again it does not apply the new rotation... Add: I realised that the "image" is applied as per the layer. So I need to figure out how to re apply the stylemap to the layer so it will trigger the "update" on the page. //redefine layer 2 so it can be updated - test.js is just a 0.0 ref// var layer2 = new OpenLayers.Layer.GML("Layer 2", "test.js", { format: OpenLayers.Format.GeoJSON, styleMap: styleMap }); But even if I add the above into my function still no luck. Included map.addLayers([layer2]); into the function as well. Edit: Attaching stylemap: var styleMap = new OpenLayers.StyleMap({ "default": new OpenLayers.Style({ rotation: rotationv, labelXOffset: "0", labelYOffset: "-15", graphicZIndex: 1 }) });

• Alternatives to HtmlTextWriter in a System.Web.UI.Control?

  Hi, Can you use FluentHTML or other alternatives in an web application user control? Can you put a markup file in a System.Web.UI.Control like the System.Web.UI.UserControl but without the burden of the Page object? I would like to reduce the number of lines of the following code: writer.Write(SacrificalMarkupPage.GenerateControlMarkup(new DialogConfirm())); writer.AddAttribute("class", string.Format("ajaxResponse {0}", action)); writer.RenderBeginTag("div"); writer.RenderBeginTag("h4"); writer.WriteEncodedText("Delete selected item?"); writer.RenderEndTag(); //h4 var queryString = new HttpQueryString { {"confirmed", "true"}, {"src", urlReferer.PathAndQuery} }; writer.AddAttribute("href", queryString.MakeQueryString(url).PathAndQuery); writer.AddAttribute("class", "delete"); writer.RenderBeginTag("a"); writer.WriteEncodedText("Yes"); writer.RenderEndTag(); //a.delete writer.WriteEncodedText(" | "); writer.AddAttribute("href", urlReferer.PathAndQuery); writer.AddAttribute("class", "back"); writer.RenderBeginTag("a"); writer.WriteEncodedText("No"); writer.RenderEndTag(); //a.back writer.RenderEndTag(); //div.ajaxResponse.ACTION Thanks

• 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). Last call for any biters!

• jQuery ajax link, returned data includes a from that wont submit

  - by calumogg

  Hi everyone, I have a problem with the returned data from a ajax request. Basically when I click on a link it runs a ajax request to load some html into a div, that part is working fine the problem comes when the data has been loaded. Part of the html loaded is a form, this form works fine if I load the page directly but when it is loaded through ajax into the div it wont submit but the rest of the links in the html work fine. Here is the code that requests the remote html data: // Ajax to load image editing page $('a.editpicture').click(function(e) { e.preventDefault(); var picture = $(this).attr("id") $.ajax({ url: 'http://localhost/digital-xposure/index.php/members/viewpicture/' + picture, success: function(data) { $('#update-picture').html(data); } }); }); This is the form it loads: <form method="post" id="updatepicture" name="updatepicture" action="http://localhost/digital-xposure/index.php/members/editpicture"/> <p>Title<input type="text" name="title" id="title" style="input" value="<?php echo $title; ?>"></P> <p>Album<?php echo $albums;?></p> <p>Description<textarea name="description" id="description" cols="50" rows="5"><?php echo $description; ?></textarea></P> <input type="hidden" name="filename" id="filename" value="<?php echo $filename; ?>" /> <input type="button" name="update-submit" id="update-submit" value="Update details" class="button"> Or <input type="button" onClick="location.href='<?php echo base_url(); ?>index.php/members/deletepicture/<?php echo $filename; ?>'" value="Delete picture" class="button"> </form> Any ideas why the form wont submit after being loaded into the div? Any help is greatly appreciated, thanks. Calum

• Retrieve parent node from selection (range) in Gecko and Webkit

  - by Jason

  I am trying to add an attribute when using a wysiwyg editor that uses "createLink" command. I thought it would be trivial to get back the node that is created after the browse executes that command. Turns out, I am only able to grab this newly created node in IE. Any ideas? The following code demonstrates the issue (debug logs at bottom show different output in each browser): var getSelectedHTML = function() { if ($.browser.msie) { return this.getRange().htmlText; } else { var elem = this.getRange().cloneContents(); return $("<p/>").append($(elem)).html(); } }; var getSelection = function() { if ($.browser.msie) { return this.editor.selection; } else { return this.iframe[0].contentDocument.defaultView.getSelection(); } }; var getRange = function() { var s = this.getSelection(); return (s.getRangeAt) ? s.getRangeAt(0) : s.createRange(); }; var getSelectedNode = function() { var range = this.getRange(); var parent = range.commonAncestorContainer ? range.commonAncestorContainer : range.parentElement ? range.parentElement(): range.item(0); return parent; }; // **** INSIDE SOME EVENT HANDLER **** if ($.browser.msie) { this.ec("createLink", true); } else { this.ec("createLink", false, prompt("Link URL:", "http://")); } var linkNode = $(this.getSelectedNode()); linkNode.attr("rel", "external"); $.log(linkNode.get(0).tagName); // Gecko: "body" // IE: "a" // Webkit: "undefined" $.log(this.getSelectedHTML()); // Gecko: "<a href="http://site.com">foo</a>" // IE: "<A href="http://site.com" rel=external>foo</A>" // Webkit: "foo" $.log(this.getSelection()); // Gecko: "foo" // IE: [object Selection] // Webkit: "foo" Thanks for any help on this, I've scoured related questions on SO with no success!

• HTTP Basic Authentication with HTTPService Objects in Adobe Flex/AIR

  - by Bob Somers

  I'm trying to request a HTTP resource that requires basic authorization headers from within an Adobe AIR application. I've tried manually adding the headers to the request, as well as using the setRemoteCredentials() method to set them, to no avail. Here's the code: <mx:Script> <![CDATA[ import mx.rpc.events.ResultEvent; import mx.rpc.events.FaultEvent; private function authAndSend(service:HTTPService):void { service.setRemoteCredentials('someusername', 'somepassword'); service.send(); } private function resultHandler(event:ResultEvent):void { apiResult.text = event.result.toString(); } private function resultFailed(event:FaultEvent):void { apiResult.text = event.fault.toString(); } ]]> </mx:Script> <mx:HTTPService id="apiService" url="https://mywebservice.com/someFileThatRequiresBasicAuth.xml" resultFormat="text" result="resultHandler(event)" fault="resultFailed(event)" /> <mx:Button id="apiButton" label="Test API Command" click="authAndSend(apiService)" /> <mx:TextArea id="apiResult" /> However, a standard basic auth dialog box still pops up prompting the user for their username and password. I have a feeling I'm not doing this the right way, but all the info I could find (Flex docs, blogs, Google, etc.) either hasn't worked or was too vague to help. Any black magic, oh Flex gurus? Thanks. EDIT: Changing setRemoteCredentials() to setCredentials() yields the following ActionScript error: [MessagingError message='Authentication not supported on DirectHTTPChannel (no proxy).'] EDIT: Problem solved, after some attention from Adobe. See the posts below for a full explanation. This code will work for HTTP Authentication headers of arbitrary length. import mx.utils.Base64Encoder; private function authAndSend(service:HTTPService):void { var encoder:Base64Encoder = new Base64Encoder(); encoder.insertNewLines = false; // see below for why you need to do this encoder.encode("someusername:somepassword"); service.headers = {Authorization:"Basic " + encoder.toString()}; service.send(); }
