  • Disable eclipselink caching and query caching - not working?

    - by James
    I am using eclipselink JPA with a database which is also being updated externally to my application. For that reason there are tables I want to query every few seconds. I can't get this to work even when I try to disable the cache and query cache. For example: EntityManagerFactory entityManagerFactory = Persistence.createEntityManagerFactory("default"); EntityManager em = entityManagerFactory.createEntityManager(); MyLocation one = em.createNamedQuery("MyLocation.findMyLoc").getResultList().get(0); Thread.sleep(10000); MyLocation two = em.createNamedQuery("MyLocation.findMyLoc").getResultList().get(0); System.out.println(one.getCapacity() + " - " + two.getCapacity()); Even though the capacity changes while my application is sleeping the println always prints the same value for one and two. I have added the following to the persistence.xml <property name="eclipselink.cache.shared.default" value="false"/> <property name="eclipselink.query-results-cache" value="false"/> I must be missing something but am running out of ideas.

  • PHP extensions won't load on Apache startup

    - by WebDevHobo
    I've added php as a module for Apache 2.2.11: LoadModule php5_module "c:/php/php5apache2_2.dll" And also added AddType application/x-httpd-php .php And in PHP.ini, my extension dir is set to: extension_dir = "C:\php\ext" And yes, the directories are correct and all files do exist. But when I start apache, I get these errors: PHP Warning: PHP Startup: Unable to load dynamic library 'C:\php\ext\php_mysql.dll' - The specified module could not be found.\r\n in Unknown on line 0 PHP Warning: PHP Startup: Unable to load dynamic library 'C:\php\ext\php_pdo_pgsql.dll' - The specified module could not be found.\r\n in Unknown on line 0 PHP Warning: PHP Startup: Unable to load dynamic library 'C:\php\ext\php_pgsql.dll' - The specified module could not be found.\r\n in Unknown on line 0 [Sun May 17 03:46:01 2009] [notice] Apache/2.2.11 (Win32) PHP/5.2.9-2 configured -- resuming normal operations [Sun May 17 03:46:01 2009] [notice] Server built: Dec 10 2008 00:10:06 [Sun May 17 03:46:01 2009] [notice] Parent: Created child process 4652 PHP Warning: PHP Startup: Unable to load dynamic library 'C:\php\ext\php_mysql.dll' - The specified module could not be found.\r\n in Unknown on line 0 PHP Warning: PHP Startup: Unable to load dynamic library 'C:\php\ext\php_pdo_pgsql.dll' - The specified module could not be found.\r\n in Unknown on line 0 PHP Warning: PHP Startup: Unable to load dynamic library 'C:\php\ext\php_pgsql.dll' - The specified module could not be found.\r\n in Unknown on line 0 [Sun May 17 03:46:01 2009] [notice] Child 4652: Child process is running [Sun May 17 03:46:01 2009] [notice] Child 4652: Acquired the start mutex.

  • PHP create huge errors file on my server feof() fread()

    - by Nik
    I have a script that allows users to 'save as' a pdf, this is the script - <?php header("Content-Type: application/octet-stream"); $file = $_GET["file"] .".pdf"; header("Content-Disposition: attachment; filename=" . urlencode($file)); header("Content-Type: application/force-download"); header("Content-Type: application/octet-stream"); header("Content-Type: application/download"); header("Content-Description: File Transfer"); header("Content-Length: " . filesize($file)); flush(); // this doesn't really matter. $fp = fopen($file, "r"); while (!feof($fp)) { echo fread($fp, 65536); flush(); // this is essential for large downloads } fclose($fp); ?

  • iPhone Provisioning Profile problems...

    - by James
    I have already successfully submitted two apps to the app store, so I should be able to do it by now, right? With my most recent app, however, I'm having a bear of a time with getting the Application Identifier or Bundle Identifier set up. In my distribution profile, I have included the identifier "com.jmock.irowbeta", and then copied it exactly into the the app's Info.plist file under "Bundle Identifier". In the past, this has done the trick, but now I'm getting the error Provisioning profile 'irow beta' specificies the identifier 'com.jmock.irowbeta' which doesn't match the current setting 'com.yourcompany.irow-beta'. So it seems that its somehow still using the default of com.yourcompany.APPLICATION_NAME, but it shouldn't after I have changed it in the Info.plist, right? I think this means that xcode isn't recognizing that PLIST for some reason, because when I change the name of the icon file, for example, or other such attributes, nothing changes. If this is the problem, how do I make xcode recognize the PLIST? Otherwise, what the heck is going on? Thanks, James

  • Setting an delegate for the UIDatePicker animation?

    - by james.ingham
    If I had a date picker within an action sheet and called the following line: [datePicker setDate:newDate animated:YES]; And then my app hides the action sheet the date picker is within, is there anyway to set up a animation delegate so that the user see's the animation of the date picker first and then hides the action sheet? I have done this with UIView's by calling: [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(METHOD)]; However I can not see anything like this for the date picker. Thanks in advanced - James

  • Ninject - initialise objects

    - by James Lin
    Hi guys, I am new to ninject, I am wondering how I can run custom initizlisation code when constructing the injected objects? ie. I have a Sword class which implements IWeapon, but I want to pass an hit point value to the Sword class constructor, how do I achieve that? Do I need to write my own provider? A minor question, IKernel kernel = new StandardKernel(new Module1(), new Module2(), ...); what is the actual use of having multiple modules in Kernel? I sorta understand it, but could someone give me a formal explaination and use case? Thanks a lot! James

  • Passenger: "Missing these required gems redgreen"

    - by Michael Stum
    Hello, total ruby newbie, trying to setup a Rails/MongoDB application on Mac OS X Snow leopard. Installed Ruby 1.9.1 and RubyGems 1.3.7, which ruby and which gem point to the same directory. I'm using the Snow Leopard built-in apache and Passenger 2.2.11. I'm using the rails template from the mongo-site which seems to work okay overall. The exact error that passenger gives me is: /Users/User/Sites/feuerapp/vendor/rails/railties/lib/rails/gem_dependency.rb:119:Warning: Gem::Dependency#version_requirements is deprecated and will be removed on or after August 2010. Use #requirement **Notice: C extension not loaded. This is required for optimum MongoDB Ruby driver performance. You can install the extension as follows: gem install bson_ext If you continue to receive this message after installing, make sure that the bson_ext gem is in your load path and that the bson_ext and mongo gems are of the same version. Missing these required gems: redgreen You're running: ruby 1.9.1.376 at /usr/local/bin/ruby rubygems 1.3.7 at /Users/User/.gem/ruby/1.9.1, /usr/local/lib/ruby/gems/1.9.1 Runrake gems:installto install the missing gems. The weird thing is that redgreen is installed and looks fine to me: Dahlia:feuerapp User$ ls -la vendor/gems/ total 0 drwxr-xr-x 7 User staff 238 May 18 22:56 . drwxr-xr-x 5 User staff 170 May 18 23:00 .. drwxr-xr-x 11 User staff 374 May 18 22:56 factory_girl-1.2.4 drwxr-xr-x 11 User staff 374 May 18 22:56 mocha-0.9.8 drwxr-xr-x 7 User staff 238 May 18 22:56 mongo_mapper-0.7.6 drwxr-xr-x 7 User staff 238 May 18 22:56 redgreen-1.2.2 drwxr-xr-x 11 User staff 374 May 18 22:56 shoulda-2.10.3 Commenting out this line in environment.rb "solves" the issue, but that's not really want I want: config.gem 'redgreen' I don't understand anything of gems yet, but from my limited understanding, redgreen should be there and found?

  • Objective C selector memory managment (does this leak memory)?

    - by James Jones
    - (IBAction) someButtonCall { if(!someCondition) { someButtonCallBack = @selector(someButtonCall); [self presentModalViewController:someController animated:YES]; } else ... } //Called from someController - (void) someControllerFinished:(BOOL) ok { [self dismissModalViewControllerAnimated:YES]; if(ok) [self performSelector:someButtonCallBack]; else ... } I'm wondering if the user keeps getting into the !someCondition clause if the selector is leaked by assigning a new selector each time (the code above is hypothetical and not what i'm doing). Any help is appreciated. Thanks, James Jones

  • 100% height on nested table cell in IE

    - by James Cooper
    I want a nested table to expand to the height of the enclosing cell. This works as expected in Firefox/Chrome/Safari, but not in IE7 or IE8. Please see the example here: http://www.bitmechanic.com/heightDemo.html The DOCTYPE is relevant. While the demo above validates as HTML 4.01 Strict, it does not render properly in IE7. If I remove the DOCTYPE entirely, or set it to HTML 3.2, it renders properly in IE. Any suggestions on how to get this to render in 4.01 (strict or loose)? The actual web site is a bit more complicated -- changing the DOCTYPE will cause all sorts of other problems. We're struggling to understand the (presumed) IE bug here and how to work around it. thanks -- James

  • GoogleAppEngine : JAR for enhancer not found, yet ASM is on the classpath

    When deploying my application to GoogleAppEngine I'm getting the following message after the upload Exception in thread "Thread-0" You have selected to use ClassEnhancer "ASM" yet the JAR for that enhancer does not seem to be in the CLASSPATH! org.datanucleus.enhancer.NucleusEnhanceException: You have selected to use ClassEnhancer "ASM" yet the JAR for that enhancer does not seem to be in the CLASSPATH! at org.datanucleus.enhancer.DataNucleusEnhancer.init(DataNucleusEnhancer.java:212) at org.datanucleus.enhancer.DataNucleusEnhancer.addClasses(DataNucleusEnhancer.java:370) at org.datanucleus.enhancer.EnhancerProcessor$EnhanceRunnable.run(EnhancerProcessor.java:163) at java.lang.Thread.run(Thread.java:636) I'm not sure why this is happening, since I have the following in my POM <dependency> <groupId>asm</groupId> <artifactId>asm</artifactId> <version>3.2</version> </dependency> Which is required by GAE, and the ASM jar is located in the target directory, so I'm failing to see what the issue is Any ideas?

  • Reflection and changing a variables type at runtime?

    - by james-west
    Hi I'm trying to create an object Of a specific type. I've got the following code, but it fails because it can't cast the new table object to the one that is already defined. I need table to start of an IEnumerable type so I can't declare is an object. Public sub getTable(ByVal t as Type) Dim table As Table(Of Object) Dim tableType As Type = GetType(Table(Of )).MakeGenericType(t) table = FormatterServices.GetUninitializedObject(tableType) End sub So in short - is there a way of changing a variable type at runtime? (or a better way of doing what I'm doing) Thanks in advance. James

  • Better to build or buy a compute grid platform?

    - by James B
    I am looking to do some quite processor-intensive brute force processing for string matching. I have run my prototype in a multi-threaded environment and compared the performance to an implementation using Gridgain with a couple of nodes (also multithreaded). The performance I observed was that my Gridgain implementation performed slower to my multithreaded implementation. It could be the case that there was a flaw in my gridgain implementation, but it was only a prototype, and I thought the results were indicative. So my question is this: What are the advantages of having to learn and then build an implementation for a particular grid platform (hadoop, gridgain, or EC2 if going hosted - other suggestions welcome), when one could fairly easily put together a lightweight compute grid platform with a much shallower learning curve?...i.e. what do we get for free with these cloud/grid platforms that are worth having/tricky to implement? (Please note, I don't have any need for a data grid) Cheers, -James (p.s. Happy to make this community wiki if needbe)

  • Concatenating text in an ASP.NET localized label

    - by James B
    Trying to localize text in ASP.NET labels... want to add a ':' after the localized text. I could just add the ':' to the localized text in the resource file, but that seems silly... there should be an easy way to do this. <asp:Label id="RoleTypeLabel" runat="server" Text='<%$ Resources: GS3, RoleTypeLabel %>:' AssociatedControlID="RoleTypeDropDown"></asp:Label> (note the ':' at the end of Text='...') Of course, this doesn't work... and neither does anything I can think of to concatenate a ':' onto the end of the localized text. Anyone know how to do it? TIA, James

  • PHP application variable... maybe?

    - by James
    I went to a PHP job interview, I was asked to implement a piece of code to detect visitors are bots to crawl thru the website and steal content. So I implemented a few lines of code to detect if the site is being refreshed/visited too quickly/often by using a session variable to store last visit timestamp. I got told that session varaibles can be manupilated by cookies etc, so I am wondering if there is a application variable that I can use to store the timestamp information against visitor IPs eg $_SERVER[REMOTE_ADDR]? I know that I can write the data to a file but it's not very good for a high traffic website. Regards James

  • How to make a DropDownList control display some items in bold ASP.Net

    - by james lewis
    I'm working with a custom DropDownList control in ASP.Net and there's been a request to display certain items in the list with a bold typeface (NOTE - the control inherits from CompositeDataBoundControl so it can be data bound... not DropDownListBox). The control is bound to a table and there's a column in the table named IsUsed - if this is set to true, the corresponding item in the list should be rendered bold. (It should be noted here that this will only ever be viewed in FireFox.) My experience is all in the middle \ backend tiers so the presentation layer is very new to me - can someone point me in the right direction? My initial thought was that somewhere in the custom control I would have access to all the rows that are returned from the data source which I could cycle through etc but I'm not sure if that's possible... There's also RenderContents which I can override... looks interesting! Any help appreciated - cheers. James

  • Updating GUI axes in MATLAB

    - by James
    HI, I am making a GUI for a program I have created, where I need to be able to change the position of a load along a beam. I have set up the axes and the slider properly, but I am unsure how to get the axes to update, as I can't find any examples that show how to do this on the internet. At present, as I move the load, the position updates properly, but the old position stays on screen as well, which is quite annoying. Can anyone recommend any good examples that show how to do this, or does anyone have a suggestion of how to go about refreshing the axes? Regards, James

  • How to add a timeout value when using Java's Runtime.exec()?

    - by James Adams
    I have a method I am using to execute a command on the local host. I'd like to add a timeout parameter to the method so that if the command being called doesn't finish in a reasonable amount of time the method will return with an error code. Here's what it looks like so far, without the ability to timeout: public static int executeCommandLine(final String commandLine, final boolean printOutput, final boolean printError) throws IOException, InterruptedException { Runtime runtime = Runtime.getRuntime(); Process process = runtime.exec(commandLine); if (printOutput) { BufferedReader outputReader = new BufferedReader(new InputStreamReader(process.getInputStream())); System.out.println("Output: " + outputReader.readLine()); } if (printError) { BufferedReader errorReader = new BufferedReader(new InputStreamReader(process.getErrorStream())); System.out.println("Error: " + errorReader.readLine()); } return process.waitFor(); } Can anyone suggest a good way for me to implement a timeout parameter? Thanks in advance for any suggestions! --James

  • Free for personal use license?

    - by Lance May
    I'm trying desperately to find a software licensing model that would allow me to make my product completely open to the public domain for personal use/modification, but would be able to be sold commercially. I know such a beast exists, and I'm sure in many flavors. I just can't find it. ;( What I'm hoping for is a way to allow people the opportunity to benefit from the product in an "open source" fashion, while still allowing me to have a revenue on it to be able to continue development full time. Thanks much in advance.

  • How do I catch jQuery $.getJSON (or $.ajax with datatype set to 'jsonp') error when using JSONP?

    - by Andy May
    Is it possible to catch an error when using JSONP with jQuery? I've tried both the $.getJSON and $.ajax methods but neither will catch the 404 error I'm testing. Here is what I've tried (keep in mind that these all work successfully, but I want to handle the case when it fails): jQuery.ajax({ type: "GET", url: handlerURL, dataType: "jsonp", success: function(results){ alert("Success!"); }, error: function(XMLHttpRequest, textStatus, errorThrown){ alert("Error"); } }); And also: jQuery.getJSON(handlerURL + "&callback=?", function(jsonResult){ alert("Success!"); }); I've also tried adding the $.ajaxError but that didn't work either: jQuery(document).ajaxError(function(event, request, settings){ alert("Error"); }); Thanks in advance for any replies!

  • Why won't asp.net create cookies in localhost?

    - by James McConnell
    Okay, this is really kinda starting to bug me. I have a simple Web project setup located at: "C:\Projects\MyTestProject\". In IIS on my machine, I have mapped a virtual directory to this location so I can run my sites locally (I understand I can run it from Visual Studio, I like this method better). I have named this virtual directory "mtp" and I access it via http://localhost/mtp/index.aspx. All this is working fine. However, whenever I try to create a cookie, it simply never gets written out? I've tried this in FF3 and IE7 and it just plain won't write the cookie out. I don't get it. I do have "127.0.0.1 localhost" in my hosts file, I can't really think of anything else I can do. Thanks for any advice. James

  • NHibernate Unique Constraint on Name and Parent Object fails because NH inserts Null

    - by James
    Hi, I have an object as follows Public Class Bin Public Property Id As Integer Public Property Name As String Public Property Store As Store End Class Public Class Store Public Property Id As Integer Public Property Bins As IEnumerable(Of Bin) End Class I have a unique constraint in the database on Bin.Name and BinStoreID to ensure unique names within stores. However, when NHibernate persists the store, it first inserts the Bin records with a null StoreID before performing an update later to set the correct StoreID. This violates the Unique Key If I persist two stores with a Bin of the same name because The Name columns are the same and the StoreID is null for both. Is there something I can add to the mapping to ensure that the correct StoreID is included in the INSERT rather than performing an update later? We are using HiLo identity generation so we are not relying on DB generated identity columns Thanks James
