  • google appengine local datastore integration testing with spring

    - by mirror303
    Hi all, I want to write some integration tests to see how my spring-managed DAO's behave when talking to the appengine datastore. Following the spring manual I will be providing my test-classes with the proper annotations: @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations = { "classpath:applicationContext.xml" }) After a lot of browsing I found this blog post dating back to august '09 from somebody doing exactly what I want to achieve. It involves writing a TestEnvironment class that implements ApiProxy.Environment plus talking to ApiProxyLocalImpl. However, if I look at the current docs (for version 1.3.1), it seems that this has been replaced by newing an instance of the framework provided LocalDatastoreServiceTestConfig which is passed to a LocalServiceTestHelper. It is too bad that the appengine docs don't show an example how to do this with JPA because then the spring wiring would be trivial. Trying to follow the route outlined in the blog posting has me running into a compiler messages telling me that classes such as ApiProxyLocalImpl are not visible by me. Hence, there must be a new way of doing it, which probably involves the LocalServiceTestHelper. My question: Does anybody know how? I know I will need to configure an EntityManagerFactory and provide it with the Datastore connection somehow... but how? :)

  • jQTouch Spinning Wheel (Cubiq) Implementation Won't Work

    - by Peter
    I am trying to get a nice Spinning Wheel working within my webapp; http://bit.ly/89oWud However, I keep receiving an error within Mobile Safari that the variable 'blabla' cannot be found. I have implemented both of these suggested solutions: 1# Change SpinningWheelCSS 2# Change JQTouch CSS, JS files, and add JQTouch wrapper to body Neither worked for me. I am trying to use the incredible Spinning Wheel by Cubiq.org. I'm likely doing something wrong, but for the life of me I can't figure out what it is. Help is very much appreciated.

  • iPhone apps: Webapps or native?

    - by jpartogi
    Hi all, I am planning to create an iPhone apps version for our online webapps. I am still new to iPhone apps development so I don't know whether to choose iPhone native or a webapps that runs on iPhone browser. The requirement is actually pretty basic. The iPhone apps need to submit data and get data from the database that is also used by the webapps. User would have the same access to the webapps, only I want this specific to iPhone, as the user experience would be different using a webapps and iPhone apps. I am also interested to sell the application on Apple store. Based on your experience, what would be better for this kind of requirement, iPhone native or webapps? What are the drawbacks building a native iPhone apps and webapps that runs on iPhone browser? Also, am I only limited to Objective-C to build a native iPhone apps? Or is there any other framework for that? Please be gentle on me, I am not starting a flamewar.

  • GAE Task Queue oddness

    - by b3nw
    I have been testing the taskqueue with mixed success. Currently I am using the default queue, in default settings ect ect.... I have a test url setup which inserts about 8 tasks into the queue. With short order, all 8 are completed properly. So far so good. The problem comes up when I re-load that url twice under say a minute. Now watching the task queue, all the tasks are added properly, but only the first batch execute it seems. But the "Run in Last Minute" # shows the right number of tasks being run.... The request logs tell a different story. They show only the first set of 8 running, but all task creation urls working successfully. The oddness of this is that if I wait say a minute between the task creation url requests, it will work fine. Oddly enough changing the bucket_size or execution speed does not seem to help. Only the first batch are executed. I have also reduced the number of requests all the way down to 2, and still found only the first 2 execute. Any others added display the same issues as above. Any suggestions? Thanks

  • c# Unit Test: Writing to Settings in unit test does not save values in user.config

    - by HorstWalter
    I am running a c# unit test (VS 2008). Within the test I do write to the settings, which should result in saving the data to the user.config. Settings.Default.X = "History"; // X is string Settings.Default.Save(); But this simply does not create the file (I have crosschecked under "C:\Documents and Settings\HW\Local Settings\Application Data"). If I create the same stuff as a Console application, there is no problem persisting the data (same code). Is there something special I need to consider doing this in a UnitTest?

  • Android app (with felix) crashes with LinearAlloc exceeded capacity

    - by user1106000
    I am running apache felix and an osgi app on android (3.2). This works pretty well so far, but I have rather large chunks of data to load into the application (osgi bundles). The problem with that is that when I load the biggest chunk of data I get LinearAlloc exceeded capacity The error seems to come from LinearAlloc.c \#define DEFAULT_MAX_LENGTH (4*1024*1024) if (nextOffset > pHdr->mapLength) { /* * We don't have to abort here. We could fall back on the system * malloc(), and have our "free" call figure out what to do. Only * works if the users of these functions actually free everything * they allocate. */ LOGE("LinearAlloc exceeded capacity, last=%d\n", (int) size); dvmAbort(); } afaik in 3.2/4.x it is even 8*1024*1024, but I still hit that limit. I'm looking to get better insight on what causes this problem and how I might possibly be able to fix it. Any help would be appreciated.

  • Applescript access to last.fm app via application icon in menu bar

    - by Mark
    Hi, I want to create an Applescript to drive the last.fm player app. I'm trying to do this via last.fm application icon in the menu bar rather than using the main application menus, as this approach (I think) won't cause last.fm to switch to the foreground. The overall plan is to bind my script to a quicksilver trigger so I can stop|start|skip|love|ban|tag tracks from the keyboard. My problem is I can't find what UI element to bind the applescript to. I've used UI Browser to scan through the UI object model but it draws a blank with the last.fm icon in the menu bar. Any thoughts appreciated.

  • WM_POWERBROADCAST handler for CMainDlg in ATL app not invoked

    - by psychotik
    I have an ATL app where I want to handle WM_POWERBROADCAST. I have a CMainDlg (CAxDialogImpl) in whose MSG_MAP I defined the handler. BEGIN_MSG_MAP(CMainDlg) ... MESSAGE_HANDLER(WM_POWERBROADCAST, OnPowerChange) ... END_MSG_MAP() However, the handler isn't invoked when I do things that should invoke it, for instance change power settings or put the machine to sleep. Any ideas about what might be going on, and how to fix this? Does CMainDlg not get notified of power events, for some reason?

  • External config file to be used by multiple DLLs.

    - by vikp
    Hi, I have multiple DLLs that are used to read/write data into my database. There is a presentation layer DLL and a data access layer DLL. I want these DLLs to share a set of the connection strings. My idea is to store the connection string in a seperate DLL in the external configuration file. I'm not sure whether it's a good idea and whether I can reference that external DLL in both presentation and data access layers. The other question is whether I should write a helper class to read the data from the external config file or whether I should be using built in .Net methods? Thank you

  • Good Guide For Web App Security?

    - by QAH
    Hello! I am pretty good on making web applications and I know how to transfer data to and from client/server, etc. I need some help though learning how to make the data exchanges more secure. That is the reason why I feel kind of scared to publish any web app I make. I wanted to know what are some good guides to help you understand and learn how to secure data transfer with your web application? Things like better authentication for example and making better logins. You can post any suggestion, but just for your information, I mainly code my web apps with Javascript and PHP. Also, I transfer my data using JSON or XML. Thanks a lot

  • Appengine datastore phantom entity - inconsistent state?

    - by aloo
    Getting a weird error on java appengine code that used to work fine (nothing has changed but the data in the datastore). I'm trying to iterate over the results of a query and change a few properties of the entities. The query does return a set of results, however, when I try to access the first result in the list, it throws an exception when trying to access any of its properties (but its key). Here's the exception: org.datanucleus.state.JDOStateManagerImpl isLoaded: Exception thrown by StateManager.isLoaded Could not retrieve entity of kind OnTheCan with key OnTheCan(3204258) org.datanucleus.exceptions.NucleusObjectNotFoundException: Could not retrieve entity of kind OnTheCan with key OnTheCan(3204258) at org.datanucleus.store.appengine.DatastoreExceptionTranslator.wrapEntityNotFoundException(DatastoreExceptionTranslator.java:60) And here is my code: PersistenceManager pm = PMF.get().getPersistenceManager(); Query query = null; List<OnTheCan> cans; query = pm.newQuery("SELECT this FROM " + OnTheCan.class.getName() + " WHERE open == true ORDER BY onTheCanId ASC"); query.setRange(0, num); cans = (List<OnTheCan>) query.execute(); for (OnTheCan c : cans) { System.err.println(c.getOnTheCanId()); // this works fine! getting the key works c.setOpen(false); // failure here with the above exception c.setAutoClosed(true); c.setEndTime(new Date(c.getStartTime().getTime() + 600000/*10*60*1000*/)); } pm.close(); The code throws the exception when trying to execute c.setOpen(false) - thats the first time I'm accessing or setting a property that isnt the key. So it seems there is a phantom entity in my datastore with key 3204258. THis entity doesn't really exist (queried the datastore from admin console) but for some reason its being returned by the query. Could my data store be in an inconsistent state? I've managed the following workaround by placing it as the first line in my for loop. Clearly an ugly hack: if (c.getOnTheCanId() == 3204258) { continue; } Any ideas?

  • iPhone App link to iStore for commission

    - by Simon
    Is it possible to link from an iPhone application to the iStore so a user can (a) play a sample of music and then navigate to that track in order to buy it? In a bit more detail: the application lists a number of tracks for a particular artist (a recommendation by the app based on user criteria). The user scrolls down the list and finds a track that they are interested in. They play the 30 second sample (as you would in the iStore) and then, if they like it, they press on a link that takes them to the iStore where they can purchase the track. If they buy the track, then the application gets 5% of the money paid for the track. I have looked through the web and found a number of suggestions but nothing seems to fit the specification above. I would be very grateful if anyone is able to tell me whether this is possible and some clues as to how it would be done. Thanks, Simon...

Only slight annoyance is that when developing new plugins, I don't get intellisense on classes inside the App_Code directory. Currently I am creating them in another directory inside my project and then copying them into App_Code. is there any way around this?
