• Using a JSON web service from a Java client application

  - by user383341

  I am developing a client-side Java application that has a bit of functionality that requires getting data from some web services that transmit in JSON (some RESTful, some not). No JavaScript, no web browser, just a plain JAR file that will run locally with Swing for the GUI. This is not a new or unique problem; surely there must be some open source libraries out there that will handle the JSON data transmission over HTTP. I've already found some that will parse JSON, but I'm having trouble finding any that will handle the HTTP communication to consume the JSON web service. So far I've found Apache Axis2 apparently which might have at least part of the solution, but I don't see enough documentation for it to know if it will do what I need, or how to use it. Maybe part of the problem is that I don't have experience with web services so I'm not able to know a solution when I see it. I hope some of you can point me in the right direction. Examples would be helpful.

• IE 7 can't bind event (using .live()) to dynamically created element using .load()

  - by petron

  Hi All - I'm having trouble getting IE7 to keep a click event bound to an element that is added to the DOM using .load(). Here's some code: $('.mybtn').live('click', function(e){ e.preventDefault(); $('#mypage').load('load-this-page.htm'); }); And here's the html <div id="mypage"> <a href="#" class="mybtn">clickme</a> // stuff goes here </div> On page load the click works but once the div is loaded via the clickme link the click stops working in IE7. The clickme link is within the div on load and also within the load() loaded html file that's why I'm using live(). This code works in FF 3.6, fyi. Anyone have any idea what's up (besides the fact the IE sucks balls)? Thanks!

• Problem with url_for in ActionMailer template

  - by macek

  I'm attempting to provide a confirmation link in my user welcome email and I'm getting the following Rails error: Need controller and action! It makes a fuss about this line: <p>Please take a moment to activate your account by going to: <%= link_to confirm_user_url(:id => @user.confirmation_code) %>.</p> In my development.rb environment, I have the following line: config.action_mailer.default_url_options = { :host => "localhost", :port => 3000 } There's no problem with the @user variable. I've tested the email with things like @user.username and @user.confirmation_code. I'm only getting trouble with url_for and named routes like confirm_user_url. When I check my routes with rake routes, confirm_user shows up, so it's not an issue with the named route not existing. I can't seem to figure it out. What gives?

• How can you pass GET values to another url in php? GET value forwarding

  - by gobackpacking

  Ok, so I'm using Jquery's AJAX function and it's having trouble passing a URL with a http address. So I'm hoping to "get" the GET values and send them to another URL — so: a local php file begin passed GET values, which in turn forwards the GET values to another url. Maybe curl is the answer? I don't know. It's got to be a very short answer I know. pseudo code: //retrieve the GET values $var retrieve [GET] //passing it to another url send get values to url ($var, url_address)

• how does a research topic fit into a program?

  - by Asj

  My project is supposed to be about creating a program to help put a math test online. The program should generate questions that vary on each run of the test, and it should grade the test after someone takes it. (I found out recently that there's a system that can do some of the tasks already, but I don't think many people know how to use it) What type of research could be involved? I need to find a research article that relates to my project, and I'm having a lot of trouble figuring out what type of subject to look for.

• CruiseControl.NET merge nunit and nant output

  - by JK

  I've just started using ccnet so I'm having trouble understanding why the merging of nant and nunit outputs are not working. I've setup my ccnet.config with typical values as found on google: <merge> <files> <file>D:\ccnet\path1\nant-results.xml</file> <file>D:\ccnet\path2\TestResult.xml</file> </files> </merge> <xmllogger /> Nant and ccnet are half working: if I deliberately put in a code error, then ccnet will say build failed. The same happens if I deliberately put in a failing test, ccnet will say build failed. But the ViewBuildReport.aspx page does not show any of the output from nant or nunit. Obviously I must be missing something, but I don't know what, any ideas? Thanks, JK

• Why does the infobox in my MSN Map not close?

  - by meder

  I'm having a bit of trouble with this map, invoked by the "View our interactive map" button in the middle of the content area. If you double click a point such as 8 which causes a zoom and then afterwards it causes the info box to appear, the hide logic is wrong. If you try to close the x, it will fail. This is probably because the user clicked too fast and the map thinks its in zoom mode when infact it should be in info box mode. Has anyone ran into this issue before? Looks like I have to mess around with window.ero.hide and some other functions.. because map.HideInfoBox doesn't hide the map. EDIT: The script used is here. I did not code it, but the relevant bit has: onclick="EnableEroHide();map.HideInfoBox();changePin();return false;" The map.HideInfoBox() should hide the info box.

• Windows Mobile 6.5 Running Program List Icon

  - by CNutt

  I've got an windows mobile 6.5 application I'm developing and am having trouble with one icon.

• getting a combo box that has a row source equal to a query - and the query takes data from a form -

  - by primus285

  I have a combo box with a row source based on an SQL query about like SELECT DISTINCT Database_New.ASEC FROM Database_New WHERE Database_New.Date= DateSerial([cboYear], 1, 1) And Database_New.Date<= DateSerial([cboYear], 12, 31); the trouble is that if I change the value of cboYear, the values in the drop down cboASEC do not update. I have to open the query, save it and close it to get the thing to update while I have the form open. Is there a way to get the cboASEC to update somehow? maybe a little tidbit of code in the cboYear - afterupdate?

• Where does the data model go in a Prism app?

  - by HawkeyeJoeS

  I'm having trouble where to put our data model in our Prism app. Most, if not all or our data will be coming from web services and the web services are unique for each module. Unfortunately, there will be objects that need to be shared (such as a person/user object). I'm really torn about whether to add these services directly to the module, so that each is truly independent, or create a separate project to house the web service proxies and business entities. The modules are being built by different teams, but will all live in the same solution (and source control, of course).

• What does :this means in Ruby on Rails?

  - by Marco

  Hi, I'm new to the Ruby and Ruby on Rails world. I've read some guides, but i've some trouble with the following syntax. I think that the usage of :condition syntax is used in Ruby to define a class attribute with some kind of accessor, like: class Sample attr_accessor :condition end that implicitly declares the getter and setter for the "condition" property. While i was looking at some Rails sample code, i found the following examples that i don't fully understand. For example: @post = Post.find(params[:id]) Why it's accessing the id attribute with this syntax, instead of: @post = Post.find(params[id]) Or, for example: @posts = Post.find(:all) Is :all a constant here? If not, what does this code really means? If yes, why the following is not used: @posts = Post.find(ALL) Thanks

• Getting unique items from NSMutableArray

  - by Gidogeek

  Hi Guys, I have a question about Objective-C today involving NSMutableArray. Coming from a .net/c# background I'm having some trouble working with these things. Let's say I have an object called "Song" My song has 3 properties: Title Artist Genre I have a NSMutableArray or NSArray wich holds all my Song objects. How would I go about trying to 'query' my array to get a new array with only (Unique) Artists or Genre's. Where as in .net you would write a simple LINQ query with a DISTINCT clause, how would one solve this in Objective-C ? I'm guessing with predicates but am struggling to find a solution. Thanks in advance.

• arg function not using URL alias

  - by cinqoTimo

  I am running Drupal 6, and I'm using PHP for block visibility. <?php $city = arg(0); $page = arg(1); if ($city == 'tampa' && $page != 'art'){ return 'TRUE'; } else{ return FALSE; } ?> I was having trouble with this block of code, so I decided to insert: <?php print arg(0).arg(1); ?> in my page.tpl.php. What I found was that on some of my pages, arg(0) was showing 'node' when the URL is actually 'tampa', and of course, arg(1) is showing the node ID. However, on other pages, such as my calendar, arg(0) is actually showing 'tampa' instead of 'node'. I have used this a lot in the past, and have never had this problem. Is there a reason why Drupal is disregarding my aliases on certain pages? If so, how can I fix it?

• WCF client hangs on response

  - by JohnIdol

  I have a WCF client (running on Win7) pointing to a WebSphere service. All is good from a test harness (a little test fixture outside my web app) but when my calls to the service originate from my web project one of the calls is extremely slow to deserialize (it takes up to 10 times longer) and not just the first time. I can see from fiddler that the response comes back quickly but then the WCF client hangs on the response itself for more than a minute before the next line of code is hit by the debugger, almost if the client was having trouble deserializing. This happens only if in the response I have a given pdf string, base64 encoded chunked. If for example the service raises a fault (this pdf string is not there) then the response is deserialized immediately. Again, If I send the exact same envelope through Soap-UI or from outside the web project all is good. I am at loss - What should I be looking for and is there some config setting that might do the trick? Any help appreciated!

• global applied stylesheet link on debian box

  - by James

  Hi there, Having some trouble identifying what is wrong with my link to an external CSS stylesheet... I am using a debian box to host some things... including a file i am accessing page.py which is located in /var/www/cgi-bin. I need this page to link to a css file which currently has the pathname /var/www/styles.css. Now I know I could link as: <link rel="stylesheet" href="**../styles.css**" type="text/css"> and the problem is solved but I would rather have a 'global' link, that I can use in other py files elsewhere in my filesystem and they will all point to /var/www/styles.css The information I have searched suggests that <link rel="stylesheet" href="**/var/www/styles.css**" type="text/css"> should work fine... but it doesn't. I have tried multiple combinations of everything I know but it doesn't seem to link as I would expect. Can anyone point me in the right direction?

• Selecting a sequence NEXTVAL for multiple rows

  - by stringpoet

  I am building a SQL Server job to pull data from SQL Server into an Oracle database through a linked server. The table I need to populate has a sequence for the name ID, which is my primary key. I'm having trouble figuring out a way to do this simply, without some lengthy code. Here's what I have so far for the SELECT portion (some actual names obfuscated): SELECT (SELECT NEXTVAL FROM OPENQUERY(MYSERVER, 'SELECT ORCL.NAME_SEQNO.NEXTVAL FROM DUAL')), psn.BirthDate, psn.FirstName, psn.MiddleName, psn.LastName, c.REGION_CODE FROM Person psn LEFT JOIN MYSERVER..ORCL.COUNTRY c ON c.COUNTRY_CODE = psn.Country MYSERVER is the linked Oracle server, ORCL is obviously the schema. Person is a local table on the SQL Server database where the query is being executed. When I run this query, I get the same exact value for all records for the NEXTVAL. What I need is for it to generate a new value for each returned record. I found this similar question, with its answers, but am unsure how to apply it to my case (if even possible): Query several NEXTVAL from sequence in one satement

• MySQL Access in Php to a database created in C-Panel

  - by Rhys Drury

  Basically, i'm having trouble connecting to a mysql database using a php web page. I created the database in C-panel using the wizard i'm connecting like this $db_host = "localhost"; //your host Database address $db_username = "xxxx"; //your account username $db_pass = "xxxxx"; //your account password $db_name = "xxxxx"; //your database name @mysql_connect("$db_host","$db_username","$db_pass") or die ("could not connect to mysql"); @mysql_select_db("$db_name") or die ("no database"); But all my page seems to do is trigger the " could not connect to mysql" my page does have wordpress installed at the minute but I'm planning to get rid of it as I'm creating my site myself. I'm just baffled why it can't connect, because in Phpmyadmin ( a feature on C-panel) it says the database is in localhost.

• How do I create a Magento module or widget that will appear on the shopping cart page?

  - by user303449

  I’m having a lot of trouble understanding how to create a module that will add an extra button to the shopping cart page. I found lots of info on payment modules and stand-a-lone page modules, but nothing for this. I simply need to add a button underneath the regular “Checkout” button that can post item data to another website. I’ve created a module but can’t get Magento to recognize it and display the button on that spot. Any help would be greatly appreciated, even just sending me to an existing tutorial that I haven’t been able to find. Thanks.

• MySQL LEFT JOIN, GROUP BY and ORDER BY not working as required

  - by Simon

  I have a table 'products' => ('product_id', 'name', 'description') and a table 'product_price' => ('product_price_id', 'product_id', 'price', 'date_updated') I want to perform a query something like SELECT `p`.*, `pp`.`price` FROM `products` `p` LEFT JOIN `product_price` `pp` ON `pp`.`product_id` = `p`.`product_id` GROUP BY `p`.`product_id` ORDER BY `pp`.`date_updated` DESC As you can probably guess the price changes often and I need to pull out the latest one. The trouble is I cannot work out how to order the LEFT JOINed table. I tried using some of the GROUP BY functions like MAX() but that would only pull out the column not the row. Thanks.

• Android how do I wait until a service is actually connected?

  - by Ryan

  I have an Activity calling a Service defined in IDownloaderService.aidl: public class Downloader extends Activity { IDownloaderService downloader = null; // ... In Downloader.onCreate(Bundle) I tried to bindService Intent serviceIntent = new Intent(this, DownloaderService.class); if (bindService(serviceIntent, sc, BIND_AUTO_CREATE)) { // ... and within the ServiceConnection object sc I did this public void onServiceConnected(ComponentName name, IBinder service) { Log.w("XXX", "onServiceConnected"); downloader = IDownloaderService.Stub.asInterface(service); // ... By adding all kinds of Log.xx I found that the code after if(bindService(...)) actually goes BEFORE ServiceConnection.onServiceConnected is being called - that is, when downloader is still null - which gets me into trouble. All the samples in ApiDemos avoid this timing problem by only calling services when triggered by user actions. But what should I do to right use this service after bindService succeeds? How can I wait for ServiceConnection.onServiceConnected being called reliably?

• Is it possible to write a SQL query to return specific rows, but then join some columns of those row

  - by Rob

  I'm having trouble wrapping my head around how to write this query. A hypothetical problem that is that same as the one I'm trying to solve: Say I have a table of apples. Each apple has numerous attributes, such as color_id, variety_id and the orchard_id they were picked from. The color_id, variety_id, and orchard_id all refer to their respective tables: colors, varieties, and orchards. Now, say I need to query for all apples that have color_id = '3', which refers to yellow in the colors table. I want to somehow obtain this yellow value from the query. Make sense? Here's what I was trying: SELECT * FROM apples, colors.id WHERE color_id = '3' LEFT JOIN colors ON apples.color_id = colors.id
