  • Hibernate Transient Extends problem

    - by mrvreddy
    @MappedSuperclass public abstract class BaseAbstract implements Serializable{ private static final long serialVersionUID = 1L; protected String test = //some random value; public String getTest() { return test; } public void setTest(String test){ this.test = test; } } @Entity public class Artist extends BaseAbstract { private static final long serialVersionUID = 1L; private Integer id; @override @Transient public String getTest() { return test; } ..... } My question is... when i am trying to do any operation on the artist, along with id and name, test is also getting saved which should not be the case... if i add the same transient on the baseabstract class getTest() method, i see test column NOT getting created(ideally what it should happen) but if i try to override the method with adding annotaion in the sub class it creates the test column... I dont know why this is happening since when hibernate is creating the artist object and checks for annotations, it should see the transient annotation present on the getTest() of artist method...and should not create a column in the database... Let me know if you need any clarification.... Any response on this is greatly appreciated.... Thank you

  • Post complex types to WebApi Client

    - by BumbleBee
    I am new to WebAPI. I have a MVC project and webApi project both reside under the **same solution**. Also, BLL Class library and DAL class library reside under the same solution. Earlier, my MVC project will talk to the BLL now I am trying to create a WebAPi project which stands in between MVC and BLL. Here is what I have come up with so far : I'm using the HTTPClient to post to a WebApi project. My post method on my controller accepts a single parameter (a model). StatsCriteria criteria = new StatsCriteria(); ...... var client = new HttpClient(); var response = client.PostAsJsonAsync("http://localhost:52765/api/reports", criteria).Result; ....... Here's the signature for my controller in Webapi [HttpPost] public CMAReportVM Reports([FromBody] StatsCriteria criteria) { var cmaReport = Service3.GetCMAReport(criteria.Mlsnums); //Create Map to enable mapping business object to View Model Mapper.CreateMap<CMAReport, CMAReportVM>(); // Maps model to VM model class var cmaVM = Mapper.Map<CMAReport, CMAReportVM>(cmaReport); reutn cmaVM; } // and here's my routing: config.Routes.MapHttpRoute( name: "DefaultApi", routeTemplate: "api/{controller}/{id}", defaults: new { id = RouteParameter.Optional } I am getting the following 405 : Method not allowed. As the WebAPI and MVC project both reside under same sloution I am not sure where/how to host my webapi.

  • Ruby on Rails controller and architecture with cells

    - by dt
    I decided to try to use the cells plugin from rails: http://cells.rubyforge.org/community.html given that I'm new to Ruby and very used to thinking in terms of components. Since I'm developing the app piecemeal and then putting it together piece by piece, it makes sense to think in terms of components. So, I've been able to get cells working properly inside a single view, which calls a partial. Now, what I would like to be able to do (however, maybe my instincts need to be redirected to be more "Rails-y"), is call a single cell controller and use the parameters to render one output vs. another. Basically, if there were a controller like: def index params[:responsetype] end def processListResponse end def processSearchResponse end And I have two different controller methods that I want to respond to based on the params response type, where I have a single template on the front end and want the inner "component" to render differently depending on what type of request is made. That allows me to reuse the same front-end code. I suppose I could do this with an ajax call instead and just have it rerender the component on the front end, but it would be nice to have the option to do it either way and to understand how to architect Rails a bit better in the process. It seems like there should be a "render" option from within the cells framework to render to a certain controller or view, but it's not working like I expect and I don't know if I'm even in the ballpark. Thanks!

  • How can I kill off a Python web app on GAE early following a redirect?

    - by Mike Hayes
    Hi Disclaimer: completely new to Python from a PHP background Ok I'm using Python on Google App Engine with Google's webapp framework. I have a function which I import as it contains things which need to be processed on each page. def some_function(self): if data['user'].new_user and not self.request.path == '/main/new': self.redirect('/main/new') This works fine when I call it, but how can I make sure the app is killed off after the redirection. I don't want anything else processing. For example I will do this: class Dashboard(webapp.RequestHandler): def get(self): some_function(self) #Continue with normal code here self.response.out.write('Some output here') I want to make sure that once the redirection is made in some_function() (which works fine), that no processing is done in the get() function following the redirection, nor is the "Some output here" outputted. What should I be looking at to make this all work properly? I can't just exit the script because the webapp framework needs to run. I realise that more than likely I'm just doing things in completely the wrong way any way for a Python app, so any guidance would be a great help. Hopefully I have explained myself properly and someone will be able to point me in the right direction. Thanks

  • Where can I get software-related legal advice?

    - by musicfreak
    Whenever someone asks a legal question here on SO, the response is usually something along the lines of "we are not lawyers." Okay, that's legitimate, but in that case, how can I talk to a lawyer about software-related legal matters? I could look through the phone book and find a local lawyer, but then I have no way of knowing whether the lawyer knows anything about software. (And I hear most local lawyers charge for your time, even if it's just a simple question.) Is there maybe some kind of online service for this sort of thing? For now, I'm just looking for some basic advice, so something free would be awesome, even if the "quality" is not as good. However, I'll still take any kind of paid services--I'll keep them in mind for the future. You can give me anything from a forum or QA site (like this one) to a professional service. Just remember that I'm looking specifically for software-related legal advice. I'm sure most lawyers know a thing or two about software, but I'd rather talk to someone who legitimately knows his stuff than someone who can only guess.

  • return ArrayList from spring controller for ajax call and render in second dropdown

    - by user1708125
    I've a spring bean with 3 Maps all of which are to be populated incrementally. First map is an item category list, second map is a product list and third map is a hobby for item type list All the maps are mapped to and on the JSP. When the page is loaded only the first map is populated on the onchange event of first map, I need to populate the second map in the bean and similarly on the onchange event of second map, I need to populate the third map in the bean. Is there a way to do this using Ajax?? I need some code samples to how to render JSON response in second and third dropdown. Clarification: @Donal: I have a simple JSP page with 3 dropdowns corresponding to 3 maps stored in my commandBean. So when the page loads for the first time only the first map and hence the first dropdown is populated. Now whenever the user selects anything out of the first dropdown, I need to send the same commandbean back with the values of the first dropdown and get the values for the second map and hence the second dropdown and so forth for the 3rd dropdown as well. For each dropdown I 've got 3 maps and 3 variables for storing the selected values. Now I want to understand if this is possible using Ajax. I hope this clarifies whatever you need to know. Thanx

  • How to check if new version of Chrome is available?

    - by serg
    I am trying to build an extension that would notify a user when new version of Chrome is available. I tried to inspect network traffic when Chrome is checking for an update and it is sending a request to http://74.125.95.113/service/update2?w=3:{long_encoded_string} page that returns XML with information I need: <?xml version="1.0" encoding="UTF-8"?> <gupdate xmlns="http://www.google.com/update2/response" protocol="2.0" server="prod"> <daystart elapsed_seconds="31272"/> <app appid="{8A69D345-D564-463C-AFF1-A69D9E530F96}" status="ok"> <updatecheck status="noupdate"/> <ping status="ok"/> </app> </gupdate> Besides sending {long_encoded_string} as URL parameter it is also sending some encoded cookie. Maybe someone familiar with Chrome build process can shed some light on those encoded strings and how to build them? Maybe there is another easier way (I have a feeling that string encoding is a dead end for me)?

  • web service slowdown

    - by user238591
    Hi, I have a web service slowdown. My (web) service is in gsoap & managed C++. It's not IIS/apache hosted, but speaks xml. My client is in .NET The service computation time is light (<0.1s to prepare reply). I expect the service to be smooth, fast and have good availability. I have about 100 clients, response time is 1s mandatory. Clients have about 1 request per minute. Clients are checking web service presence by tcp open port test. So, to avoid possible congestion, I turned gSoap KeepAlive to false. Until there everything runs fine : I bearly see connections in TCPView (sysinternals) New special synchronisation program now calls the service in a loop. It's higher load but everything is processed in less 30 seconds. With sysinternals TCPView, I see that about 1 thousands connections are in TIME_WAIT. They slowdown the service and It takes seconds for the service to reply, now. Could it be that I need to reset the SoapHttpClientProtocol connection ? Someone has TIME_WAIT ghosts with a web service call in a loop ?

  • Strange behavior while returning csv file from spring controller

    - by Fanooos
    I working in a spring application which have an action method that returns a CSV file. This action works fine but in some cases it throws a predefined exception (MyAppException). I have another method that is annotated @ExceptionHandler(MyAppException.class) In the exception handler method I return another csv file but with different contents. The code that returns the csv file is almost the same in the two methods. List<String[]> list= new ArrayList<String[]>(); list.add(new String[]{ integrationRequestErrorLog.getErrorMessage(), Long.toString(integrationRequestErrorLog.getId()), Integer.toString(integrationRequestErrorLog.getErrorCode()) }); CSVWriter writer = new CSVWriter(response.getWriter(), ','); writer.writeAll(list); writer.close(); the difference between the two method is the list of contents. In the first method the file is returned normally while in the exception handler method I have a strange behavior. The exception handler method works fine with Opera browser while it gives me a 404 with FireFox. Opera browser give me 404 also but it download the file while firefox does not? Really I do not understand what is the difference here.

  • ASP.Net MVC - how can I easily serialize query results to a database?

    - by Mortanis
    I've been working on a little property search engine while I learn ASP.Net MVC. I've gotten the results from various property database tables and sorted them into a master generic property response. The search form is passed via Model Binding and works great. Now, I'd like to add pagination. I'm returning the chunk of properties for the current page with .Skip() and .Take(), and that's working great. I have a SearchResults model that has the paged result set and various other data like nextPage and prevPage. Except, I no longer have the original form of course to pass to /Results/2. Previously I'd have just hidden a copy of the form and done a POST each time, but it seems inelegant. I'd like to serialize the results to my MS SQL database and return a unique key for that results set - this also helps with a "Send this query to a friend!" link. Killing two birds with one stone. Is there an easy way to take an IQueryable result set that I have, serialize it, stick it into the DB, return a unique key and then reverse the process with said key? I'm using Linq to SQL currently on a MS SQL Express install, though in production it'll be on MS SQL 2008.

  • _beginthreadx and socket

    hi, i have a question about the _beginthreadx function In the third and fourth parameter: if i have this line to create the thread hThread=(HANDLE)_beginthreadex(0,0, &RunThread, &m_socket,CREATE_SUSPENDED,&threadID ); m_socket is the socket that i want inside the thread (fourth parameter) and i have the RunThread function (third parameter) in this way static unsigned __stdcall RunThread (void* ptr) { return 0; } It is sufficient to create the thread independently if m_socket has something or not? Thanks in advance Thank you for the response Ciaran Keating helped me understand better the thread I'll explain a little more the situation I´m creating the tread in this function inside a class public: void getClientsConnection() { numberOfClients = 1; SOCKET temporalSocket = NULL; firstClient = NULL; secondClient = NULL; while (numberOfClients < 2) { temporalSocket = SOCKET_ERROR; while (temporalSocket == SOCKET_ERROR) { temporalSocket = accept(m_socket, NULL, NULL); //----------------------------------------------- HANDLE hThread; unsigned threadID; hThread=(HANDLE)_beginthreadex(0,0, &RunThread, &m_socket,CREATE_SUSPENDED,&threadID ); WaitForSingleObject( hThread, INFINITE ); if(!hThread) printf("ERROR AL CREAR EL HILO: %ld\n", WSAGetLastError()); //----------------------------------------------- } if(firstClient == NULL) { firstClient = temporalSocket; muebleC1 = temporalSocket; actionC1 = temporalSocket; ++numberOfClients; printf("CLIENTE 1 CONECTADO\n"); } else { secondClient = temporalSocket; muebleC2 = temporalSocket; actionC2 = temporalSocket; ++numberOfClients; printf("CLIENTE 2 CONECTADO\n"); } } } What i'm trying to do is to have the socket inside the thread while wait for a client connection Is this feasible as i have the code of the thread? I can change the state of the thread that is not a problem Thanks again

  • Why isn't this company contacting me? [closed]

    - by Alan
    I had a phone screen the other day with a company that I really want to work for. It went pretty well, based on cues from the HR person, such as "Next step we're going to send you a programming test," and "Well, before I get ahead of myself, do you want to continue the interviewing process." and "We'll send out the test later this afternoon. It doesn't sound like you'll have trouble with it, but I want to be honest we do have a high failure rate on it." The questions asked weren't technical, just going down my resume, and talking about the work I've done, and how it relates to the position. Nothing I couldn't talk through. This was last Thursday. It's now Tuesday, and haven't received the test yet. I sent a follow up email yesterday to the lady who interviewed me, but haven't gotten a response. Anyone had a similar experience? Am I reading too much into this? Or was I off the mark by thinking I had moved on to the next step in the interview process. Since this is a company I really want to work for, I'm driving myself insane enumerating all the various what-if scenarios.

  • GWT with JPA - no persistence provider...

    - by meliniak
    GWT with JPA There are two projects in my eclipse workspace, let's name them: -JPAProject -GWTProject JPAProject contains JPA configuration stuff (persistence.xml, entity classes and so on). GWTProject is an examplary GWT project (taken from official GWT tutorial). Both projects work fine alone. That is, I can create EMF (EntityManagerFactory) in JPAProject and get entities from the database. GWTProject works fine too, I can run it, fill the field text in the browser and get the response. My goal is to call JPAProject from GWTProject to get entities. But the problem is that when calling DAO, I get the following exception: [WARN] Server class 'com.emergit.service.dao.profile.ProfileDaoService' could not be found in the web app, but was found on the system classpath [WARN] Adding classpath entry 'file:/home/maliniak/workspace/emergit/build/classes/' to the web app classpath for this session [WARN] /gwttest/greet javax.persistence.PersistenceException: No Persistence provider for EntityManager named emergitPU at javax.persistence.Persistence.createEntityManagerFactory(Unknown Source) at javax.persistence.Persistence.createEntityManagerFactory(Unknown Source) at com.emergit.service.dao.profile.JpaProfileDaoService.<init>(JpaProfileDaoService.java:19) at pl.maliniak.server.GreetingServiceImpl.<init>(GreetingServiceImpl.java:21) . . . at org.mortbay.jetty.HttpConnection.handle(HttpConnection.java:380) at org.mortbay.io.nio.SelectChannelEndPoint.run(SelectChannelEndPoint.java:395) at org.mortbay.thread.QueuedThreadPool$PoolThread.run(QueuedThreadPool.java:488) [ERROR] 500 - POST /gwttest/greet (127.0.0.1) 3812 bytes I guess that the warnings at the beginning can be omitted for now. Do you have any ideas? I guess I am missing some basic point. All hints are highly apprecieable.

  • Android: How to periodically send location to a server

    - by Mark
    Hi, I am running a Web service that allows users to record their trips (kind of like Google's MyTracks) as part of a larger app. The thing is that it is easy to pass data, including coords and other items, to the server when a user starts a trip or ends it. Being a newbie, I am not sure how to set up a background service that sends the location updates once every (pre-determined) period (min 3 minutes, max 1 hr) until the user flags the end of the trip, or until a preset amount of time elapses. Once the trip is started from the phone, the server responds with a polling period for the phone to use as the interval between updates. This part works, in that I can display the response on the phone, and my server registers the user's action. Similarly, the trip is closed server-side upon the close trip request. However, when I tried starting a periodic tracking method from inside the StartTrack Activity, using requestLocationUpdates(String provider, long minTime, float minDistance, LocationListener listener) where minTime is the poll period from the server, it just did not work, and I'm not getting any errors. So it means I'm clueless at this point, never having used Android before. I have seen many posts here on using background services with handlers, pending intents, and other things to do similar stuff, but I really don't understand how to do it. I would like the user to do other stuff on the phone while the updates are going on, so if you guys could point me to a tutorial that shows how to actually write background services (maybe these run as separate classes?) or other ways of doing this, that would be great. Thanks!

  • OpenGL ES and real world development

    - by Mark
    Hi Guys, I'm trying to learn OpenGL ES quickly (I know, I know, but these are the pressures that have been thrusted upon me) and I have been read around a fair bit, which lots of success at rendering basic models, some basic lighting and 'some' texturing success too. But this is CONSTANTLY the point at which all OpenGL ES tutorials end, they never say more of what a real life app may need. So I have a few questions that Im hoping arent too difficult. How do people get 3d models from their favorite 3d modeling tool into the iPhone/iPad application? I have seen a couple of blog posts where people have written some python scripts for tools like Blender which create .h files that you can use, is this what people seem to do everytime? Or do the "big" tooling suites (3DS, Maya, etc...) have exporting features? Say I have my model in a nice .h file, all the vertexes, texture points, etc.. are lined up, how to I make my model (say of a basic person) walk? Or to be more general, how do you animate "part" of a model (legs only, turn head, etc...)? Do they need to be a massive mash-up of many different tiny models, or can you pre-bake animations these days "into" models (somehow) Truely great 3D games for the iPhone are (im sure) unbelievably complex, but how do people (game dev firms) seem to manage that designer/developer workflow? Surely not all the animations, textures, etc... are done programatically. I hope these are not stupid questions, and in actual fact, my app that Im trying to investigate how to make is really quite simple, just a basic 3D model that I want to be able to pan/tilt around using touch. Has anyone ever done/seen anything like this that I might be able to read up on? Thanks for any help you can give, I appreciate all types of response big or small :) Cheers, Mark

  • Providing downloads on ASP.net website

    - by Dave
    I need to provide downloads of large files (upwards of 2 GB) on an ASP.net website. It has been some time since I've done something like this (I've been in the thick-client world for awhile now), and was wondering on current best practices for this. Ideally, I would like: To be able to track download statistics: # of downloads is essential; actual bytes sent would be nice. To provide downloads in a way that "plays nice" with third-party download managers. Many of our users have unreliable internet connections, and being able to resume a download is a must. To allow multiple users to download the same file simultaneously. My download files are not security-sensitive, so providing a direct link ("right-click to download...") is a possibility. Is just providing a direct link sufficient, letting IIS handle it, and then using some log analyzer service (any recommendations?) to compile and report the statistics? Or do I need to intercept the download request, store some info in a database, then send a custom Response? Or is there an ASP.net user control (built-in or third party) that does this? I appreciate all suggestions.

  • FormsAuthentication authCookie is null only for some users

    - by mbalkema
    I am experiencing a strange problem with asp.net forms authentication. This problem only occurs for 3 users out of 30+ users that have successfully logged in. I am using very basic auth code that I have used many times and have never seen this problem. After the users successfully authenticates and the auth cookie is created, cookie added, and response.redirect to FormsAuthentication.GetRedirect(userid, false) is called. The Application_AuthenticateRequest method in Global.asax is hit. // Extract the forms authentication cookie string cookieName = FormsAuthentication.FormsCookieName; HttpCookie authCookie = Context.Request.Cookies[cookieName]; if (null == authCookie) { // There is no authentication cookie. return; } So immediately after a "good" cookie is saved and the redirect occurs the cookie is null. I have run the code through the debugger and the cookie is only null on these 3 users. But the cookie looks the same as the cookie for the many users that login successfully. Any ideas? This is standard code that should just work.

  • PHP Check slave status without mysql_connect timeout issues

    - by Jonathon
    I have a web-app that has a master mysql db and four slave dbs. I want to handle all (or almost all) read-only (SELECT) queries from the slaves. Our load-balancer sends the user to one of the slave machines automatically, since they are also running Apache/PHP and serving webpages. I am using an include file to setup the connection to the databases, such as: //for master server (i.e. - UPDATE/INSERT/DELETE statements) $Host = "10.0.0.x"; $User = "xx"; $Password = "xx"; $Link = mysql_connect( $Host, $User, $Password ); if( !$Link ) ) { die( "Master database is currently unavailable. Please try again later." ); } //this connection can be used for READ-ONLY (i.e. - SELECT statements) on the localhost $Host_Local = "localhost"; $User_Local = "xx"; $Password_Local = "xx"; $Link_Local = mysql_connect( $Host_Local, $User_Local, $Password_Local ); //fail back to master if slave db is down if( !$Link_Local ) ) { $Link_Local = mysql_connect( $Host, $User, $Password ); } I then use $Link for all update queries and $Link_Local as the connection for SELECT statements. Everything works fine until the slave server database goes down. If the local db is down, the $Link_Local = mysql_connect() call takes at least 30 seconds before it gives up on trying to connect to the localhost and returns back to the script. This causes a huge backlog of page serves and basically shuts down the system (due to the extremely slow response time). Does anyone know of a better way to handle connections to slave servers via PHP? Or, is there some kind of timeout function that could be used to stop the mysql_connect call after 2-3 seconds? Thanks for the help. I searched the other mysql_connect threads, but didn't see any that addressed this issue.

  • My python program always brings down my internet connection after several hours running, how do I debug and fix this problem?

    - by Shane
    I'm writing a python script checking/monitoring several server/websites status(response time and similar stuff), it's a GUI program and I use separate thread to check different server/website, and the basic structure of each thread is using an infinite while loop to request that site every random time period(15 to 30 seconds), once there's changes in website/server each thread will start a new thread to do a thorough check(requesting more pages and similar stuff). The problem is, my internet connection always got blocked/jammed/messed up after several hours running of this script, the situation is, from my script side I got urlopen error timed out each time it's requesting a page, and from my FireFox browser side I cannot open any site. But the weird thing is, the moment I close my script my Internet connection got back on immediately which means now I can surf any site through my browser, so it must be the script causing all the problem. I've checked the program carefully and even use del to delete any connection once it's used, still get the same problem. I only use urllib2, urllib, mechanize to do network requests. Anybody knows why such thing happens? How do I debug this problem? Is there a tool or something to check my network status once such situation occurs? It's really bugging me for a while... By the way I'm behind a VPN, does it have something to do with this problem? Although I don't think so because my network always get back on once the script closed, and the VPN connection never drops(as it appears) during the whole process.

  • Custom Header in ASIHTTPREQUEST

    - by Sharon Nathaniel
    Here is my problem. I am using ASIHTTPREQUEST to send request and get response. Now my need of the time is to upload a image,audio , video or docs via PUT method with a custom header . The header takes filename , filesize,sha256sum,username,mediatype,resume as parameters. Here is the code how I am doing that . -(void)uploadFile { NSString *resume =@"0"; NSUserDefaults *userCredentials =[NSUserDefaults standardUserDefaults]; NSString *userName =[userCredentials objectForKey:@"userName"]; NSArray *objects =[NSArray arrayWithObjects:selectedMediaType,delegate.fileName,userName,fileSize,fileSHA256Sum,resume, nil]; NSArray *keys =[NSArray arrayWithObjects:@"mediatype",@"file_name",@"usrname",@"filesize",@"sha256sum",@"resume", nil]; discSentValue =[NSDictionary dictionaryWithObjects:objects forKeys:keys]; NSURL *url = [NSURL URLWithString:@"http://briareos.code20.com/putmedia.php"]; uploadMedia = [ASIFormDataRequest requestWithURL:url]; [uploadMedia addRequestHeader:@"MEDIA_UPLOAD_CUSTOM_HEADER" value:[discSentValue JSONRepresentation]]; [uploadMedia setData:dataToUpload forKey:@"File"]; [uploadMedia setDelegate:self]; [uploadMedia setRequestMethod:@"PUT"]; [uploadMedia startAsynchronous]; } But the server is unable to recognize the header , it always returns "invalid header"
