• Eclipse+PyDev+GAE memcache error

  - by bocco

  I've started using Eclipe+PyDev as an environment for developing my first app for Google App Engine. Eclipse is configured according to this tutorial. Everything was working until I start to use memcache. PyDev reports the errors and I don't know how to fix it: Error: Undefined variable from import: get How to fix this? Sure, it is only PyDev checker problem. Code is correct and run on GAE. UPDATE: I'm using PyDev 1.5.0 but experienced the same with 1.4.8. My PYTHONPATH includes (set in Project Properties/PyDev - PYTHONPATH): C:\Program Files\Google\google_appengine C:\Program Files\Google\google_appengine\lib\django C:\Program Files\Google\google_appengine\lib\webob C:\Program Files\Google\google_appengine\lib\yaml\lib UPDATE 2: I took a look at C:\Program Files\Google\google_appengine\google\appengine\api\memcache\__init__.py and found get() is not declared as memcache module function. They use the following trick to do that (I didn't hear about such possibility): _CLIENT = None def setup_client(client_obj): """Sets the Client object instance to use for all module-level methods. Use this method if you want to have customer persistent_id() or persistent_load() functions associated with your client. Args: client_obj: Instance of the memcache.Client object. """ global _CLIENT var_dict = globals() _CLIENT = client_obj var_dict['set_servers'] = _CLIENT.set_servers var_dict['disconnect_all'] = _CLIENT.disconnect_all var_dict['forget_dead_hosts'] = _CLIENT.forget_dead_hosts var_dict['debuglog'] = _CLIENT.debuglog var_dict['get'] = _CLIENT.get var_dict['get_multi'] = _CLIENT.get_multi var_dict['set'] = _CLIENT.set var_dict['set_multi'] = _CLIENT.set_multi var_dict['add'] = _CLIENT.add var_dict['add_multi'] = _CLIENT.add_multi var_dict['replace'] = _CLIENT.replace var_dict['replace_multi'] = _CLIENT.replace_multi var_dict['delete'] = _CLIENT.delete var_dict['delete_multi'] = _CLIENT.delete_multi var_dict['incr'] = _CLIENT.incr var_dict['decr'] = _CLIENT.decr var_dict['flush_all'] = _CLIENT.flush_all var_dict['get_stats'] = _CLIENT.get_stats setup_client(Client()) Hmm... Any idea how to force PyDev to recognize that?

• I'm trying to grasp the concept of creating a program that uses a MS SQL database, but I'm used to r

  - by Sergio Tapia

  How can I make a program use a MS SQL server, and have that program work on whatever computer it's installed on. If you've been following my string of questions today, you'd know that I'm making an open source and free Help Desk suite for small and medium businesses. The client application. The client application is a Windows Forms app. On installation and first launch on every client machine, it'll ask for the address of the main Help Desk server. The server. Here I plan to handle all incoming help requests, show them to the IT guys, and provide WCF services for the Client application to consume. My dilemma lies in that, I know how to make the program run on my local machine; but I'm really stumped on how to make this work for everyone who wants to download and install the server bit on their Windows Server. Would I have to make an SQL Script and have it run on the MS SQL server when a user wants to install the 'server' application? Many thanks to all for your valuable time and effort to teach me. It's really really appreciated. :)

• Application error passthru when using apache mod_proxy

  - by user303442

  Heyas. I'm using mod_proxy with apache2 provide vhost ability to multiple servlet apps running on the local machine. It works fine, for the most part. Requests come into apache then are directed to the application bound on a port on localhost. The app receives the request and responds, which is delivered back to the client by apache. The problem I'm having is that the application delivers 500's on errors, and mod_proxy stomps on them. Often these errors are caused in a ajax request and the error is handled in client side javascript. For example, a call to a server side createObject(name) might throw a NameNotUniqueException , which is delivered back as a 500. The client javascript might then display an appropriate error message. When an error is thrown by the application (resulting in a 500 response to mod_proxy), then apache stomps the error message and returns 500 Internal Server Error Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request. .. the stock apache server side error message. I want mod_proxy to pass the original 500 back through to the client. Is there a directive I've missed which prevents clobbering of the 500? TIA

• HttpSendRequest not getting latest file from server

  - by Doug Kavendek

  I am having an issue with my HTTP requests in my app, such that if the remote file is the same size as the local file (even though its modified time is different, as its contents have been changed), attempts to download it return quickly and the newer file is not downloaded. In short, the process I am following is: Setting up an HTTP connection with the INTERNET_FLAG_RESYNCHRONIZE flag and calling HttpSendRequest(); then checking the HTTP status code and finding it to be "200". If the remote file is updated, but remains the same size as the local copy: The local file is unchanged after running the app. If I call HttpQueryInfo() with HTTP_QUERY_LAST_MODIFIED after sending the request, it gives me the actual last modified time of the server's file, which I can see is different from the local file I am trying to have it overwrite. If the remote file is updated, and the file size becomes different from the local copy: It is downloaded and overwrites the local copy as expected. Here's a fairly abridged version of the code, to cut out helpers and error checking: // szAppName = our app name HINTERNET hInternetHandle = InternetOpen( szAppName, INTERNET_OPEN_TYPE_PRECONFIG, NULL, NULL, 0 ); // szServerName = our server name hInternetHandle = InternetConnect( hInternetHandle, szServerName, INTERNET_DEFAULT_HTTP_PORT, NULL, NULL, INTERNET_SERVICE_HTTP, NULL, 0 ); // szPath = the file to download LPCSTR aszDefault[2] = { "*/*", NULL }; DWORD dwFlags = 0 | INTERNET_FLAG_IGNORE_REDIRECT_TO_HTTP | INTERNET_FLAG_IGNORE_REDIRECT_TO_HTTPS | INTERNET_FLAG_KEEP_CONNECTION | INTERNET_FLAG_NO_AUTH | INTERNET_FLAG_NO_AUTO_REDIRECT | INTERNET_FLAG_NO_COOKIES | INTERNET_FLAG_NO_UI | INTERNET_FLAG_RESYNCHRONIZE; HINTERNET hHandle = HttpOpenRequest( hInternetHandle, "GET", szPath, NULL, NULL, aszDefault, dwFlags, 0 ); DWORD dwTimeOut = 10 * 1000; // In milliseconds InternetSetOption( hInternetHandle, INTERNET_OPTION_CONNECT_TIMEOUT, &dwTimeOut, sizeof( dwTimeOut ) ); InternetSetOption( hInternetHandle, INTERNET_OPTION_RECEIVE_TIMEOUT, &dwTimeOut, sizeof( dwTimeOut ) ); InternetSetOption( hInternetHandle, INTERNET_OPTION_SEND_TIMEOUT, &dwTimeOut, sizeof( dwTimeOut ) ); DWORD dwRetries = 5; InternetSetOption( hInternetHandle, INTERNET_OPTION_CONNECT_RETRIES, &dwRetries, sizeof( dwRetries ) ); HttpSendRequest( hInternetHandle, NULL, 0, NULL, 0 ); Since I have found I can query the remote file's last modified time, and find it to be accurate, I know it's actually getting to the server. I thought that specifying INTERNET_FLAG_RESYNCHRONIZE would force the file to resynch if it's out of date. Do I have it all wrong? Is this just how it's supposed to work?

• Java - encrypt / decrypt user name and password from a configuration file

  - by nzpcmad

  We are busy developing a Java web service for a client. There are two possible choices: Store the encrypted user name / password on the web service client. Read from a config. file on the client side, decrypt and send. Store the encrypted user name / password on the web server. Read from a config. file on the web server, decrypt and use in the web service. The user name / password is used by the web service to access a third-party application. The client already has classes that provide this functionality but this approach involves sending the user name / password in the clear (albeit within the intranet). They would prefer storing the info. within the web service but don't really want to pay for something they already have. (Security is not a big consideration because it's only within their intranet). So we need something quick and easy in Java. Any recommendations? The server is Tomkat 5.5. The web service is Axis2. What encrypt / decrypt package should we use? What about a key store? What configuration mechanism should we use? Will this be easy to deploy?

• Email not sent until application closes

  - by Tester101

  I have an application that uses SmtpClient to send E-Mail, but the E-Mails are not sent until the application closes. I have searched and searched to find a solution to the problem, but I am not able to find one. The system does have Symantec anti-virus installed, which could possibly be the problem. Does anybody have a solution to this problem? Here is the code I am using. public class EMail { private string server; public string Server {get{return this.server;}set{this.server = value;}} private string to; public string To {get{return this.to;}set{this.to = value;}} private string from; public string From {get{return this.from;}set{this.from = value;}} private string subject; public string Subject {get{return this.subject;}set{this.subject = value;}} private string body; public string Body {get{return this.body;}set{this.body = value;}} public EMail() {} public EMail(string _server, string _to, string _from, string _subject, string _body) { this.Server = _server; this.To = _to; this.From = _from; this.Subject = _subject; this.Body = _body; } public void Send() { System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage(this.From, this.To, this.Subject, this.Body); message.IsBodyHtml = true; System.Net.Mail.SmtpClient client = new System.Net.Mail.SmtpClient(this.Server); client.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network; //I have tried this, but it still does not work. //client.ServicePoint.ConnectionLeaseTimeout = 0; try { client.Send(message); } catch(System.Exception ex) { System.Windows.Forms.MessageBox.Show(ex.ToString()); } message.Dispose(); } }

• Web application date time localization best practice at 201x

  - by Hieu Lam

  Hi all, I have worked for various web projects but correct date time localization have not been done and considered throroughly so I want to ask this very typical problem here and I want to hear comments from expert in this problem What is the correct strategy for storing a date/time value from client from server As I understand, because of locale and timezone so we have to do the conversion, I have heard about GMT or UTC time and after do some search it seems that UTC is more accurate ? so we will convert from client time - UTC+0 when saving and when we read the value from server to client, we convert from server time back to client time again ? However, I see in some website, at the bottom have the sentence "All times are in UTC", "All times are in GMT" and also "All times are in your local time". So maybe not all the sites do the convertion back and forth ? And in that case the user has to manually do the date/time conversion ? How to display the date/time convenient to user based on his locale and region How to provide personalization on date/time value ? I had one time depends on vbscript to do the display and the format is read from windows regional and format settings automatically. But without vbscript how can we determine a date/time pattern for a user of a specific locale. Do we have to store a mapping between a locale and pattern somewhere and do the conversion at the server side ? Although date/time conversion is needed in most case, there's situation where only date matter for example if my birthday is 2 Feb 1980, it should be the same for all locale and no conversion should be done. How can we address this issue.

• Dependency isn't included in my assembly, although scope is "compile"

  - by Bernhard V

  Hi! I have the following dependency specified in my project's pom: <dependency> <groupId>org.jboss.client</groupId> <artifactId>jbossall-client</artifactId> <scope>compile</scope> </dependency> My project itself has to be the child of another pom. And in that one, the following is defined: <dependency> <groupId>jboss</groupId> <artifactId>jbossall-client</artifactId> <version>4.2.2</version> <scope>provided</scope> <type>jar</type> </dependency> When I now assembly my program, it seems that the "provided" scope of the parent pom overrides the scope of my project, since the jbossall-client-jar is not included in my assembly. Although it seems illogical to me, maybe it's this feature taking effect here. Do you know a way to include the dependency in my assembly without touching the parent pom?

• Trouble adding video controls to video selected by XML comboBox

  - by user560128

  Hello, it's been a few years since I've touched flash, so perhaps I'm just overlooking something. If anyone could look at the code and offer any suggestions that would be awesome. What's working, I select a video from a combobox that is populated from an XML file, pick the video and it plays. I've been trying to add pause/play, stop, forward and reverse functionality, once I get that to work I also want to add a video scrubber(slider), and previous/next buttons to go to the previous/next video as listed in the xml file. At the moment I have a component button on the stage called playButton, which I'm trying to use for pause/play functionality. Below is my code, the player control is at the very bottom. Thanks. import fl.data.DataProvider; var nc:NetConnection = new NetConnection(); nc.connect(null); var ns:NetStream = new NetStream(nc); var videosXML:XML = new XML(); var loader:URLLoader = new URLLoader(); var request:URLRequest= new URLRequest("xml/videos.xml"); var videos:Array = new Array({label:"Select a Video",data:""}); var client:Object = new Object(); theVideo.attachNetStream(ns); ns.client = client; loader.addEventListener(Event.COMPLETE,loaderOnComplete); loader.load (request); function loaderOnComplete(event:Event):void{ videosXML = new XML(event.target.data); for each (var video:XML in videosXML.video){ videos.push({label:video.name.toString(),data:video.url.toString()}); } moviesCB.dataProvider = new DataProvider(videos); } moviesCB.addEventListener(Event.CHANGE, changeHandler); function changeHandler(event:Event):void { if(ComboBox(event.target).selectedItem.data != ""){ ns.play(ComboBox(event.target).selectedItem.data); } }; client.onMetaData = metadataHandler; function metadataHandler(md:Object):void{ } //player controls playButton.onRelease = function() { ns.pause(); }

• StreamReader.EndOfStream produces IOException

  - by Ziplin

  I'm working on an application that accepts TCP connections and reads in data until an </File> marker is read and then writes that data to the filesystem. I don't want to disconnect, I want to let the client sending the data to do that so they can send multiple files in one connection. I'm using the StreamReader.EndOfStream around my outter loop, but it throws an IOException when the client disconnects. Is there a better way to do this? private static void RecieveAsyncStream(IAsyncResult ar) { TcpListener listener = (TcpListener)ar.AsyncState; TcpClient client = listener.EndAcceptTcpClient(ar); // init the streams NetworkStream netStream = client.GetStream(); StreamReader streamReader = new StreamReader(netStream); StreamWriter streamWriter = new StreamWriter(netStream); while (!streamReader.EndOfStream) // throws IOException { string file= ""; while (file!= "</File>" && !streamReader.EndOfStream) { file += streamReader.ReadLine(); } // write file to filesystem } listener.BeginAcceptTcpClient(RecieveAsyncStream, listener); }

• Cookie not renewing/overwriting in IE

  - by deceze

  I have a weird quirk with cookies in IE. When a user logs into the site, I'm generating a new session id and hence need to overwrite the cookie. The flow is basically: Client goes to https://secure.example.com/users/login page, automatically receiving a session id Client POSTs login credentials to same address Client receives the following headers together with a 302 redirect to https://secure.example.com/users/mypage: CAKEPHP=deleted; expires=Sun, 05-Apr-2009 04:50:35 GMT; path=/ CAKEPHP=98hnIO23...; expires=Mon, 12 Apr 2010 04:50:36 GMT; path=/; secure Client is supposed to visit https://secure.example.com/users/mypage, presenting the new session id. This works in all browsers, except IE (tested in 7 & 8). IE retains the old, unauthenticated session id, and is redirected back to the login page. It works on my local test environment (using a self-signed certificate at https://localhost:8443/...), but not on the live server. I'm using CakePHP and simply issue a $this->Session->renew(), which produces the above cookie headers. Any ideas how to get IE to accept the new cookie?

• Stale connection with Pheanstalk

  - by token47

  I'm using beanstalkd to offload some work to other machines. The setup is a bit unusual, the server is on the internet (public ip) but the consumers are behind adsl lines on some peoples homes. So there is a linux server as client going out through a dynamic ip and connecting to the server to get a job. It's all PHP and I'm using pheanstalk library. Everything runs smoothly for some time, but then the adsl changes the IP (every 24h hours the provider forces a disconnect-reconnect) the client just hangs, never to go out of "reserve". I thought that putting a timeout on the reserve would help it, but it didn't. As it seems, the client issues a command and blocks, it never checks the timeout. It just issues a reserve-with-timeout (instead of a simple reserve) and it is the servers responsibility to return a TIME_OUT as the timeout occurs. The problem is, the connection is broken (but the TCP/IP doesn't know about that yet until any of the sides try to talk to the other side) and if the client blocked reading, it will never return. The library seems to have support for some kind of timeouts locally (for example when trying to connect to server), but it does not seem to contemplate this scenario. How could I detect the stale connection and force a reconnect? Is there some kind of keepalive on the protocol (and on the pheanstalk itself)? Thanks!

• How to communicate between frames?

  - by bangoker

  I'm maintaining an application that goes sort of like this: There is a Page A with a Frame that shows Page B. Now page B is part of a completely different product, so there's a frame in a that just calls B. Now, they want that when B an option in B is clicked, the WHOLE page is redirected to another page in A. The problem is that the url of A is something like "www.client.MyCompany/Order/Details/123" But B doesnt know nothing about A, or which order # it is or anything, but Page A who has the frame B does know it. For know my solution is to just redirect to all the order so something like client.MyCompany/Orders but since B doesn't know which client it is, I'll add it in the webconfig. (so each client has its own webconfig with a different value). I dont find this solution optimal but I can't think of anything else! I already tried putting the needed url in page A in a hidden Div (since A does know all the info) and then trying to read the whole DOM of the page from B to find it.... unfortunately I can only get access to Frame B's DOM... (I tried with jquery). I know frames are evil, but this is how it is written... any ideas? Thanks!

• java: can't use constructors in abstract class

• How to use associated Model as datasource for DataView

  - by Chris Gilbert

  I have a Model structure as shown below and I want to know how to use the Bookings array as the datasource of my DataView. Model Structure: Client ClientId Name Bookings (HasManyAssociation) Contacts (HasManyAssociation) AjaxProxy JsonReader (ImplicitIncludes is set to true so child models are created with one call) Booking BookingNodeId BookingDetails Contact ContactNodeId ContactDetails The above gives me a data structure as follows: Client Bookings[ Booking Booking ] Contacts[ Contact Contact ] What I want to be able to do is either, create a Store from my Bookings array and then use that store as the datasource for my DataView OR directly use the Bookings array as the datasource (I don't really care how I do it to be honest). If I setup the AjaxProxy on my Booking model it works fine but then obviously I cannot automatically create my Client and Contacts when I load my JSON. It seems to me to make sense that the Client model, being the top level model hierarchically, is the one to load the data. EDIT: I figured it out as follows (with special thanks to handet87 below for his dataview.setStore() pointer). The key in this case is to know that creating the relationship actually sets up another store called, in this case BookingsStore and ContactsStore. All I needed to do was dataview.setStore("BookingsStore")

• How do I ensure my C# software can access the internet in a Citrix + ISA environment?

  - by TomFromThePool

  Hi everyone, A client recently informed us that deployment of our software in their environment has failed due to a proxy error when the software attempts to access the internet. The client has a combination of Citrix and Microsoft's ISA server. The software allows the use of a proxy and the ability to manually enter authentication information, or automatically retrieve the current system proxy settings. The error returned is the standard 407 authentication error, but the client assures us that they have entered the authentication information required. They have also shown us the snippet of the ISA error logs which identify the client as Anonymous and the authentication protocol as Basic. I have a few questions I suppose: How should I go about dealing with the ISA server in my code? I have no real experience with this environment and am assuming that the ISA server is treated like any other proxy. If I am mistaken, what should I be doing? Does ISA allow the administrator to disallow specific authentication protocols - and if this is the case and 'Basic' auth is disallowed, would it still return a 407 error? Could the Citrix environment have caused this issue? Is there any particular way to ensure that my software will work in such an environment? Code-samples would be much appreciated. I have neither a Citrix test server or an ISA server at my disposal to carry out testing on this so I am currently trying to identify possible causes before I make the case for investment in a more robust testing environment. Thanks for any help!

• What is the best web-based File Explorer?

  - by Vincent

  I would like to know what you think is the best web-based File Explorer to manage files in a remote server through HTTP / Web. It would be preferable to have PHP or Flash technology, but any good suggestion would do. More generally, how would you allow someone to manage files on a remote server with HTTP being the only open outgoing port?
