  • Google Chrome and Firefox Rendering

    - by user13503
    When attempting to visit sites running javascript, Google Chrome and Firefox often fail to render them properly. For example, when hitting google.com/codesearch results, I just get a blank page. http://img340.imageshack.us/img340/8527/200910071518.png This rendering problem happens in both browsers on a machine running Windows XP Professional x64. Internet explorer is able to render the page just fine. Also, controls on other pages sometimes fail to respond, for example in Google Docs. Has anyone encountered this issue before in Chrome/Firefox? Do they share a common installation of the V8 javascript engine? I'm baffled by this issue. Here's the source code for the image above that Chrome loads when attempting to retrieve the page: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><script>function a(c){this.t={};this.tick=function(d,e,b){var f=b?b:(new Date).getTime();this.t[d]=[f,e]};this.tick("start",null,c)}var g=new a;window.jstiming={Timer:a,load:g};try{window.jstiming.pt=window.external.pageT}catch(h){}; </script><title></title><script language="javascript" src="/codesearch/js/CachedFile/F1A2CB189D0FCB1FF201C42BF6A5447C.cache.js"></script></head><body><iframe src="javascript:''" id="__gwt_historyFrame" style="width:0;height:0;border:0"></iframe><script>if(window.jstiming){window.jstiming.a={};window.jstiming.c=1;function k(a,d,f){var b=a.t[d];if(!b)return undefined;b=a.t[d][0];if(f!=undefined)var h=f;else h=a.t.start[0];return b-h}window.jstiming.report=function(a,d,f){var b="";if(window.jstiming.pt){b+="&srt="+window.jstiming.pt;delete window.jstiming.pt}try{if(window.external&&window.external.tran)b+="&tran="+window.external.tran}catch(h){}if(a.b)b+="&"+a.b;var e=a.t,p=e.start,l=[],i=[];for(var c in e)if(!(c=="start"))if(!(c.indexOf("_")==0)){var j= e[c][1];if(j)e[j]&&i.push(c+"."+k(a,c,e[j][0]));else p&&l.push(c+"."+k(a,c))}delete e.start;if(d)for(var m in d)b+="&"+m+"="+d[m];var n=[f?f:"http://csi.gstatic.com/csi","?v=3","&s="+(window.jstiming.sn?window.jstiming.sn:"codesearch")+"&action=",a.name,i.length?"&it="+i.join(",")+b:b,"&rt=",l.join(",")].join(""),g=new Image,o=window.jstiming.c++;window.jstiming.a[o]=g;g.onload=g.onerror=function(){delete window.jstiming.a[o]};g.src=n;g=null;return n}}; </script></body></html> Thanks, Steve

  • Is it possible to run several virtual machines each with independent mouse+keyboard on a single PC?

    - by chiurox
    My goal is to instead of buying 4 separate basic PCs (plus the obvious peripherals), buy just one fast PC and the peripherals. I'm wondering if I can use a more powerful computer, say, one with core i7 and plenty of RAM, with 2 video cards (total of 4 monitor outputs) to run 4 or more virtual machines (WinXPs) so instead of having 4 individual machines, I'll be having just one. However, the catch is, is it possible to have a pair of mouse and keyboard + input/output audio for each of these virtual machines?

  • Wake On LAN on request [closed]

    - by honzas
    Hi, I have a small home network with the router capable of running OpenWRT, is there some utility or firewall rule, which can be used to Wake On LAN on request. What I think - if I want to access my media centre (using for example SSH or HTTP) and it is suspended, is it possible to catch the ICMP packet (saying the machine is offline) and send the WOL packet to wakeup the machine and resend the SSH or HTTP request? Thanks

  • How to use USB Key in Xen 5.6 Environment?

    - by Az
    I am looking for a way to use USB key on a guest OS running on a 5.6 Xen Server environment. The catch is that I need to actually detect in the Guest OS (Win2003 Server) like an actual USB Key. Attaching it as a storage drive doesnt work (It is a key with special attributes that servers as a licensing mechanism). Just wondering if anyone has had a similar need and found a good solution? Thanks, Nate

  • Virtual Subdomains

    - by Dave P
    I would like to manage subdomains exclusively through .htaccess. I am able to catch subdomains that I set up - for example, support.testsite.com - currently, I redirect that to testsite.com/support. What I would like to do is retain the subdomain, even after the redirect - so support.testsite.com seems to stay in the address bar for the user, even though it is actually located at testsite.com/support. Should I maintain another .htaccess file in /support that rewrites the address? Thanks!

  • Having trouble binding a ksoap object to an ArrayList in Android

    I'm working on an app that calls a web service, then the webservice returns an array list. My problem is I am having trouble getting the data into the ArrayList and then displaying in a ListView.

  • ASP.NET MVC 2 UpdateModel() is not updating values in memory or database

    - by campbelt
    Hello, I am new to MVC, and so am working through the NerdDinner tutorial, here. In particular, I'm running into problems with the use of the UpdateModel method, which is explained in the part five of that tutorial. The problem is, when I try to edit the value of a dinner object using the UpdateModel method, the values do not get updated, and no exceptions are thrown. Oddly, I am not having any trouble with the Create or Delete features that are illustrated in the tutorial. Only the update feature isn't working. Below, I have included the Controller code that I am using, as well as the view markup, which is contained in both an aspx View file and an ascx Partial View file. Here is the code inside my Controller, called DinnerController.cs: // // GET: /Dinners/Edit/2 [Authorize] public ActionResult Edit(int id) { Dinner dinner = dinnerRepository.GetDinner(id); return View(new DinnerFormViewModel(dinner)); } // // POST: /Dinners/Edit/2 [AcceptVerbs(HttpVerbs.Post), Authorize] public ActionResult Edit(int id, FormCollection formValues) { Dinner dinner = dinnerRepository.GetDinner(id); try { UpdateModel(dinner); var x = ViewData.GetModelStateErrors(); // <-- to catch other ModelState errors dinnerRepository.Save(); return RedirectToAction("Details", new { id = dinner.DinnerID }); } catch { ModelState.AddRuleViolations(dinner.GetRuleViolations()); return View(new DinnerFormViewModel(dinner)); } } The line with the comment "to catch other ModelState errors" was added after reading a possible solution from another StackOverflow thread, here: http://stackoverflow.com/questions/1461283/asp-net-mvc-updatemodel-not-updating-but-not-throwing-error Unfortunately, that solution didn't help me. Here is the corresponding markup in my Dinners/Edit.aspx View: <asp:Content ID="Main" ContentPlaceHolderID="MainContent" runat="server"> <h2>Edit Dinner</h2> <% Html.RenderPartial("DinnerForm"); %> </asp:Content> Here is the corresponding markup in my DinnerForm.ascx Partial View. This Partial View file is also used by the Create feature, which is working fine: <%=Html.ValidationSummary("Please correct the errors and try again.") %> <% using (Html.BeginForm()) { %> <fieldset> <p> <label for="Title">Dinner Title:</label> <%=Html.TextBoxFor(model => Model.Dinner.Title)%> <%=Html.ValidationMessage("Title", "*") %> </p> <p> <label for="EventDate">EventDate:</label> <%=Html.TextBoxFor(model => Model.Dinner.EventDate, new { value = String.Format("{0:g}", Model.Dinner.EventDate) })%> <%=Html.ValidationMessage("EventDate", "*") %> </p> <p> <label for="Description">Description:</label> <%=Html.TextBoxFor(model => Model.Dinner.Description)%> <%=Html.ValidationMessage("Description", "*")%> </p> <p> <label for="Address">Address:</label> <%=Html.TextBoxFor(model => Model.Dinner.Address)%> <%=Html.ValidationMessage("Address", "*") %> </p> <p> <label for="Country">Country:</label> <%=Html.DropDownListFor(model => Model.Dinner.Country, Model.Countries)%> <%=Html.ValidationMessage("Country", "*") %> </p> <p> <label for="ContactPhone">ContactPhone #:</label> <%=Html.TextBoxFor(model => Model.Dinner.ContactPhone)%> <%=Html.ValidationMessage("ContactPhone", "*") %> </p> <p> <label for="Latitude">Latitude:</label> <%=Html.TextBoxFor(model => Model.Dinner.Latitude)%> <%=Html.ValidationMessage("Latitude", "*") %> </p> <p> <label for="Longitude">Longitude:</label> <%=Html.TextBoxFor(model => Model.Dinner.Longitude)%> <%=Html.ValidationMessage("Longitude", "*") %> </p> <p> <input type="submit" value="Save"/> </p> </fieldset> <% } %> In any case, I've been hitting away at this for hours, and I'm out of ideas. So, I'm hoping someone here can help nudge me in the right direction, in order to figure out what I'm doing wrong.

  • Why do I get this error when I try to push my SQLite3 to Postgresql (via Taps) on Cedar Stack?

    - by rhodee
    I've done quite a bit of research on Heroku Dev Center and I am now looking to the community for help. Here is my problem. I can not push my db to Heroku Cedar Stack. I am trying to migrate a sqlite database to postgresql via Taps gem. When I am ready to deploy I run: bundle install --without production heroku run db:push I get the following result: Running db:seed attached to terminal... up, run.17 sh: db:seed: not found heroku run rake db:migrate And when I run the migration: heroku run rake db:migrate I get the following: Running rake db:migrate attached to terminal... up, run.18 rake aborted! No Rakefile found (looking for: rakefile, Rakefile, rakefile.rb, Rakefile.rb) /usr/local/lib/ruby/1.9.1/rake.rb:2367:in `raw_load_rakefile' /usr/local/lib/ruby/1.9.1/rake.rb:2007:in `block in load_rakefile' /usr/local/lib/ruby/1.9.1/rake.rb:2058:in `standard_exception_handling' /usr/local/lib/ruby/1.9.1/rake.rb:2006:in `load_rakefile' /usr/local/lib/ruby/1.9.1/rake.rb:1991:in `run' /usr/local/bin/rake:31:in `<main>' Everytime I push to Heroku (git push heroku master) it fails because my gem file is attempting to install sqlite3 gem-even though its inside of the development and test groups in my Gemfile. My database.yml production environment still points to sqlite adapter even after I have run the following command successfully: heroku config:add BUNDLE_WITHOUT="test development" --app app_name_on_heroku Out of ideas. Please help. If its useful I can post results of my gemfile, heroku ps and logs. Cheers UPDATE: After following @John's direction I now receive the following terminal message.

  • What's the best Communication Pattern for EJB3-based applications?

    - by Hank
    I'm starting a JEE project that needs to be strongly scalable. So far, the concept was: several Message Driven Beans, responsible for different parts of the architecture each MDB has a Session Bean injected, handling the business logic a couple of Entity Beans, providing access to the persistence layer communication between the different parts of the architecture via Request/Reply concept via JMS messages: MDB receives msg containing activity request uses its session bean to execute necessary business logic returns response object in msg to original requester The idea was that by de-coupling parts of the architecture from each other via the message bus, there is no limit to the scalability. Simply start more components - as long as they are connected to the same bus, we can grow and grow. Unfortunately, we're having massive problems with the request-reply concept. Transaction Mgmt seems to be in our way plenty. It seams that session beans are not supposed to consume messages?! Reading http://blogs.sun.com/fkieviet/entry/request_reply_from_an_ejb and http://forums.sun.com/message.jspa?messageID=10338789, I get the feeling that people actually recommend against the request/reply concept for EJBs. If that is the case, how do you communicate between your EJBs? (Remember, scalability is what I'm after) Details of my current setup: MDB 1 'TestController', uses (local) SLSB 1 'TestService' for business logic TestController.onMessage() makes TestService send a message to queue XYZ and requests a reply TestService uses Bean Managed Transactions TestService establishes a connection & session to the JMS broker via a joint connection factory upon initialization (@PostConstruct) TestService commits the transaction after sending, then begins another transaction and waits 10 sec for the response Message gets to MDB 2 'LocationController', which uses (local) SLSB 2 'LocationService' for business logic LocationController.onMessage() makes LocationService send a message back to the requested JMSReplyTo queue Same BMT concept, same @PostConstruct concept all use the same connection factory to access the broker Problem: The first message gets send (by SLSB 1) and received (by MDB 2) ok. The sending of the returning message (by SLSB 2) is fine as well. However, SLSB 1 never receives anything - it just times out. I tried without the messageSelector, no change, still no receiving message. Is it not ok to consume message by a session bean? SLSB 1 - TestService.java @Resource(name = "jms/mvs.MVSControllerFactory") private javax.jms.ConnectionFactory connectionFactory; @PostConstruct public void initialize() { try { jmsConnection = connectionFactory.createConnection(); session = jmsConnection.createSession(false, Session.AUTO_ACKNOWLEDGE); System.out.println("Connection to JMS Provider established"); } catch (Exception e) { } } public Serializable sendMessageWithResponse(Destination reqDest, Destination respDest, Serializable request) { Serializable response = null; try { utx.begin(); Random rand = new Random(); String correlationId = rand.nextLong() + "-" + (new Date()).getTime(); // prepare the sending message object ObjectMessage reqMsg = session.createObjectMessage(); reqMsg.setObject(request); reqMsg.setJMSReplyTo(respDest); reqMsg.setJMSCorrelationID(correlationId); // prepare the publishers and subscribers MessageProducer producer = session.createProducer(reqDest); // send the message producer.send(reqMsg); System.out.println("Request Message has been sent!"); utx.commit(); // need to start second transaction, otherwise the first msg never gets sent utx.begin(); MessageConsumer consumer = session.createConsumer(respDest, "JMSCorrelationID = '" + correlationId + "'"); jmsConnection.start(); ObjectMessage respMsg = (ObjectMessage) consumer.receive(10000L); utx.commit(); if (respMsg != null) { response = respMsg.getObject(); System.out.println("Response Message has been received!"); } else { // timeout waiting for response System.out.println("Timeout waiting for response!"); } } catch (Exception e) { } return response; } SLSB 2 - LocationService.Java (only the reply method, rest is same as above) public boolean reply(Message origMsg, Serializable o) { boolean rc = false; try { // check if we have necessary correlationID and replyTo destination if (!origMsg.getJMSCorrelationID().equals("") && (origMsg.getJMSReplyTo() != null)) { // prepare the payload utx.begin(); ObjectMessage msg = session.createObjectMessage(); msg.setObject(o); // make it a response msg.setJMSCorrelationID(origMsg.getJMSCorrelationID()); Destination dest = origMsg.getJMSReplyTo(); // send it MessageProducer producer = session.createProducer(dest); producer.send(msg); producer.close(); System.out.println("Reply Message has been sent"); utx.commit(); rc = true; } } catch (Exception e) {} return rc; } sun-resources.xml <admin-object-resource enabled="true" jndi-name="jms/mvs.LocationControllerRequest" res-type="javax.jms.Queue" res-adapter="jmsra"> <property name="Name" value="mvs.LocationControllerRequestQueue"/> </admin-object-resource> <admin-object-resource enabled="true" jndi-name="jms/mvs.LocationControllerResponse" res-type="javax.jms.Queue" res-adapter="jmsra"> <property name="Name" value="mvs.LocationControllerResponseQueue"/> </admin-object-resource> <connector-connection-pool name="jms/mvs.MVSControllerFactoryPool" connection-definition-name="javax.jms.QueueConnectionFactory" resource-adapter-name="jmsra"/> <connector-resource enabled="true" jndi-name="jms/mvs.MVSControllerFactory" pool-name="jms/mvs.MVSControllerFactoryPool" />

  • HttpPost works in Java project, not in Android

    - by dave.c
    I've written some code for my Android device to login to a web site over https and parse some data out of the resulting pages. An HttpGet happens first to get some info needed for login, then an HttpPost to do the actual login process. The code below works great in a Java project within Eclipse which has the following Jar files on the build path: httpcore-4.1-beta2.jar, httpclient-4.1-alpha2.jar, httpmime-4.1-alpha2.jar, commons-logging-1.1.1.jar. public static MyBean gatherData(String username, String password) { MyBean myBean = new MyBean(); try { HttpResponse response = doHttpGet(URL_PAGE_LOGIN, null, null); System.out.println("Got login page"); String content = EntityUtils.toString(response.getEntity()); String token = ContentParser.getToken(content); String cookie = getCookie(response); System.out.println("Performing login"); System.out.println("token = "+token +" || cookie = "+cookie); response = doLoginPost(username,password,cookie, token); int respCode = response.getStatusLine().getStatusCode(); if (respCode != 302) { System.out.println("ERROR: not a 302 redirect!: code is \""+ respCode+"\""); if (respCode == 200) { System.out.println(getHeaders(response)); System.out.println(EntityUtils.toString(response.getEntity()).substring(0, 500)); } } else { System.out.println("Logged in OK, loading account home"); // redirect handler and rest of parse removed } }catch (Exception e) { System.out.println("ERROR in gatherdata: "+e.toString()); e.printStackTrace(); } return myBean; } private static HttpResponse doHttpGet(String url, String cookie, String referrer) { try { HttpClient client = new DefaultHttpClient(); client.getParams().setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1); client.getParams().setParameter(CoreProtocolPNames.HTTP_CONTENT_CHARSET, "UTF-8"); HttpGet httpGet = new HttpGet(url); httpGet.getParams().setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1); httpGet.setHeader(HEADER_USER_AGENT,HEADER_USER_AGENT_VALUE); if (referrer != null && !referrer.equals("")) httpGet.setHeader(HEADER_REFERER,referrer); if (cookie != null && !cookie.equals("")) httpGet.setHeader(HEADER_COOKIE,cookie); return client.execute(httpGet); } catch (Exception e) { e.printStackTrace(); throw new ConnectException("Failed to read content from response"); } } private static HttpResponse doLoginPost(String username, String password, String cookie, String token) throws ClientProtocolException, IOException { try { HttpClient client = new DefaultHttpClient(); client.getParams().setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1); client.getParams().setParameter(CoreProtocolPNames.HTTP_CONTENT_CHARSET, "UTF-8"); HttpPost post = new HttpPost(URL_LOGIN_SUBMIT); post.getParams().setParameter(CoreProtocolPNames.PROTOCOL_VERSION, HttpVersion.HTTP_1_1); post.setHeader(HEADER_USER_AGENT,HEADER_USER_AGENT_VALUE); post.setHeader(HEADER_REFERER, URL_PAGE_LOGIN); post.setHeader(HEADER_COOKIE, cookie); post.setHeader("Content-Type","application/x-www-form-urlencoded"); List<NameValuePair> formParams = new ArrayList<NameValuePair>(); formParams.add(new BasicNameValuePair("org.apache.struts.taglib.html.TOKEN", token)); formParams.add(new BasicNameValuePair("showLogin", "true")); formParams.add(new BasicNameValuePair("upgrade", "")); formParams.add(new BasicNameValuePair("username", username)); formParams.add(new BasicNameValuePair("password", password)); formParams.add(new BasicNameValuePair("submit", "Secure+Log+in")); UrlEncodedFormEntity entity = new UrlEncodedFormEntity(formParams,HTTP.UTF_8); post.setEntity(entity); return client.execute(post); } catch (Exception e) { e.printStackTrace(); throw new ConnectException("ERROR in doLoginPost(): "+e.getMessage()); } } The server (which is not under my control) returns a 302 redirect when the login was successful, and 200 if it fails and re-loads the login page. When run with the above Jar files I get the 302 redirect, however if I run the exact same code from an Android project with the 1.6 Android Jar file on the build path I get the 200 response from the server. I get the same 200 response when running the code on my 2.2 device. My android application has internet permissions, and the HttpGet works fine. I'm assuming that the problem lies in the fact that HttpPost (or some other class) is different in some significant way between the Android Jar version and the newer Apache versions. I've tried adding the Apache libraries to the build path of the Android project, but due to the duplicate classes I get messages like: INFO/dalvikvm(390): DexOpt: not resolving ambiguous class 'Lorg/apache/http/impl/client/DefaultHttpClient;' in the log. I've also tried using a MultipartEntity instead of the UrlEncodedFormEntity but I get the same 200 result. So, I have a few questions: - Can I force the code running under android to use the newer Apache libraries in preference to the Android versions? - If not, does anyone have any ideas how can I alter my code so that it works with the Android Jar? - Are there any other, totally different approaches to doing an HttpPost in Android? - Any other ideas? I've read a lot of posts and code but I'm not getting anywhere. I've been stuck on this for a couple of days and I'm at a loss how to get the thing to work, so I'll try anything at this point. Thanks in advance.

  • problem in loading images from web

    - by Lynnooi
    hi, I am new in android and had developed an app which get images from the website and display it. I got it working in emulator but not in real phones. In some device, it will crash or take very long loading period. Can anyone please help me or guide me in improving it as i'm not sure whether the way i loads the images is correct or not. Here are the code i use to get the images from the web and display accordingly. if (xmlURL.length() != 0) { try { URL url = new URL(xmlURL); SAXParserFactory spf = SAXParserFactory.newInstance(); SAXParser sp = spf.newSAXParser(); /* Get the XMLReader of the SAXParser we created. */ XMLReader xr = sp.getXMLReader(); /* * Create a new ContentHandler and apply it to the * XML-Reader */ xr.setContentHandler(myExampleHandler); /* Parse the xml-data from our URL. */ xr.parse(new InputSource(url.openStream())); /* Parsing has finished. */ /* * Our ExampleHandler now provides the parsed data to * us. */ ParsedExampleDataSet parsedExampleDataSet = myExampleHandler.getParsedData(); } catch (Exception e) { } } if (s.equalsIgnoreCase("wallpapers")) { Context context = helloAndroid.this.getBaseContext(); for (int j = 0; j <= myExampleHandler.filenames.size() - 1; j++) { if (myExampleHandler.filenames.elementAt(j).toString() != null) { helloAndroid.this.ed = myExampleHandler.thumbs.elementAt(j) .toString(); if (helloAndroid.this.ed.length() != 0) { Drawable image = ImageOperations(context, helloAndroid.this.ed, "image.jpg"); file_info = myExampleHandler.filenames .elementAt(j).toString(); author = "\nby " + myExampleHandler.authors.elementAt(j) .toString(); switch (j + 1) { case 1: ImageView imgView1 = new ImageView(context); imgView1 = (ImageView) findViewById(R.id.image1); if (image.getIntrinsicHeight() > 0) { imgView1.setImageDrawable(image); } else imgView1 .setImageResource(R.drawable.empty_wallpaper); tv = (TextView) findViewById(R.id.filename1); tv.setText(file_info); tv = (TextView) findViewById(R.id.author1); tv.setText(author); imgView1 .setOnClickListener(new View.OnClickListener() { public void onClick(View view) { // Perform action on click Intent myIntent1 = new Intent( helloAndroid.this, galleryFile.class); Bundle b = new Bundle(); b.putString("fileID",myExampleHandler.fileid.elementAt(0).toString()); b.putString("page", "1"); b.putString("family", s); b.putString("fi",myExampleHandler.folder_id.elementAt(folder).toString()); b.putString("kw", keyword); myIntent1.putExtras(b); startActivityForResult( myIntent1, 0); } }); break; case 2: ImageView imgView2 = new ImageView(context); imgView2 = (ImageView) findViewById(R.id.image2); imgView2.setImageDrawable(image); tv = (TextView) findViewById(R.id.filename2); tv.setText(file_info); tv = (TextView) findViewById(R.id.author2); tv.setText(author); imgView2 .setOnClickListener(new View.OnClickListener() { public void onClick(View view) { // Perform action on click Intent myIntent1 = new Intent( helloAndroid.this, galleryFile.class); Bundle b = new Bundle(); b.putString("fileID",myExampleHandler.fileid.elementAt(1).toString()); b.putString("page", "1"); b.putString("family", s); b.putString("fi",myExampleHandler.folder_id.elementAt(folder).toString()); b.putString("kw", keyword); myIntent1.putExtras(b); startActivityForResult( myIntent1, 0); } }); break; case 3: //same code break; } } } } } private Drawable ImageOperations(Context ctx, String url, String saveFilename) { try { InputStream is = (InputStream) this.fetch(url); Drawable d = Drawable.createFromStream(is, "src"); return d; } catch (MalformedURLException e) { e.printStackTrace(); return null; } catch (IOException e) { e.printStackTrace(); return null; } } public Object fetch(String address) throws MalformedURLException, IOException { URL url = new URL(address); Object content = url.getContent(); return content; }
