  • selective UnknownHostException

    - by Stephan
    Hi everybody! I am getting said Exception in my program, but only in certain cases. First of all, I have the internet permission set:<uses-permission android:name="android.permission.INTERNET" />, and I tried the two method of this and this thread (they don't work in my case). The scenario is the following: I send a GET request to a rest service (e.g. http://my.web.site/request.php?attr=blah) and I do get a correct xml back. Now, in this xml there are some resources described, one of which is an url to an image (e.g http://my.web.site/images/img.jpg). Here it's where it fails! Here I consistently receive a UnknownHostException. I find it weird, since it's the same domain and everything. Accessing the img url from browser works (both from the emulator browser and pc browser). I tried from a device too but it doesn't get the image anyway. Any idea on why this weird behavior? EDIT: all my tests were on emulator and device, but connected to a wifi network. I tried also using the internet connection of my provider on the phone (i.e. bypassing home network), and still the behavior is the same... I found this bug which I assume is the source of this problem, but still no solution (after more than 1.5years). Any ideas?

  • PHP get values from SimpleXMLElement array

    - by seanp2k
    I have this: [1]=> object(SimpleXMLElement)#6 (1) { ["@attributes"]=> array(14) { ["name"]=> string(5) "MySQL" ["acknowledged"]=> string(1) "1" ["comments"]=> string(1) "1" ["current_check_attempt"]=> string(1) "1" ["downtime"]=> string(1) "0" ["last_check"]=> string(19) "2010-05-01 17:57:00" ["markdown_filter"]=> string(1) "0" ["max_check_attempts"]=> string(1) "3" ["output"]=> string(42) "CRITICAL - Socket timeout after 10 seconds" ["perfdata_available"]=> string(1) "1" ["service_object_id"]=> string(3) "580" ["state"]=> string(8) "critical" ["state_duration"]=> string(6) "759439" ["unhandled"]=> string(1) "0" } } (I used var_dump($child) to generate that) How do I get the 'name' attribute out of there as a string? Here is my code: $xml = simplexml_load_string($results); foreach($xml->data->list as $child) { var_dump($child); echo $child->getName() . ": " . $child->name . "<br />"; }

  • Rails from with better url

    - by Sam
    wow, switching to rest is a different paradigm for sure and is mainly a headache right now. view <% form_tag (businesses_path, :method => "get") do %> <%= select_tag :business_category_id, options_for_select(@business_categories.collect {|bc| [bc.name, bc.id ]}.insert(0, ["All Containers", 0]), which_business_category(@business_category) ), { :onchange => "this.form.submit();"} %> <% end %> controller def index @business_categories = BusinessCategory.find(:all) if params[:business_category_id].to_i != 0 @business_category = BusinessCategory.find(params[:business_category_id]) @businesses = @business_category.businesses else @businesses = Business.all end respond_to do |format| format.html # index.html.erb format.xml { render :xml => @businesses } end end routes map.resources What I want to to is get a better url than what this form is presenting which is the following: http://localhost:3000/businesses?business_category_id=1 Without rest I would have do something like http://localhost:3000/business/view/bbq bbq as permalink or I would have done http://localhost:300/business_categories/view/bbq and get the business that are associated with the category but I don't really know the best way of doing this. So the two questions are what is the best logic of finding a business by its categories using the latter form and number two how to get that in a pretty url all through restful routes in rails.

  • "Ambiguous column name" error on one particular server

    - by jazbit
    This simple query throws the "Ambiguous column name TaskID" error on one db-server only. This is ridiculous. We tested this with the same database structure on different servers and different versions of ms sql (2005/2008), and it's only THIS particular client's server that throws the error. I'm actually frustrated. SELECT Tasks.TaskID FROM Tasks INNER JOIN TaskHelpers ON TaskHelpers.TaskID = Tasks.TaskID order by TaskID Yes, I know I can put "Tasks.TaskID" into the order by clause, but for some reasons I can't.

  • Need for J2me source code

    - by tikamchandrakar
    For J2me It strikes me as odd that you need an extra "api key" and so on. But actually, what I really want is NOT create an extra facebook application that needs to be registered on Facebook. I don't want to create any extra configuration effords necessary for the user of my application to undergo. All my user should need is his well-known login data for facebook. Everything else should be completely transparent to him. So, I thought maybe would u can do the login process, creating a request to the REST server via http. I know this would provide me with an XML. I hope that the this API will somehow automatically transform that XML into an intuitive object model that represents the facebook user data of the respective user. So, I would expect something like userData = new FacebookData(new FacebookConnection("user_name", "password")). Done. If you get, what I mean. No api key. No secret key. Just the well-known login data. Practically, the equivalent to thunderbird webmail, which allows you to access your MSN hotmail account via Thunderbird. Thunderbird webmail will automatically converts the htmls obtained from a hotmail browser login into the data structure usually passed on to a mail client. Hope you get what I mean. I was expecting the equilalent for the your API.

  • node.js: encrypting data that needs to be decrypted?

    - by fancy
    We are using bcrypt for passwords and data that never needs to be decrypted. What should do to protect other user information that does. For this example lets say that we didn't want a users real name to be in plain text in case someone was to obtain the db. This is somewhat sensitive data but also needs to be called from time to time and displayed in plain text. Is there a simple way to do this?

  • Confused about distinct/aggregate queries with (N)Hibernate

    - by nw
    I'm not sure how to approach queries that don't map 1:1 to my persistent entities - in other words, distinct and aggregate queries. For example, I need to retrieve a distinct list of property values for populating a drop-down list. Should I write a class and a mapping for the "entities" that are returned by this query? Or should I just use the native DB provider and work with native data sets instead?
