  • request response with activemq - always send double response.

    - by Chris Valley
    Hi, I'm new at activeMq. I tried to create a simple request response like this. public Listener(string destination) { // set factory ConnectionFactory factory = new ConnectionFactory(URL); IConnection connection; try { connection = factory.CreateConnection(); connection.Start(); ISession session = connection.CreateSession(); // create consumer for designated destination IMessageConsumer consumer = session.CreateConsumer(new Apache.NMS.ActiveMQ.Commands.ActiveMQQueue(destination)); consumer.Listener += new MessageListener(consumer_Listener); Console.ReadLine(); } catch (Exception ex) { Console.WriteLine(ex.ToString()); throw new Exception("Exception in Listening ", ex); } } The OnMessage static void consumer_Listener(IMessage message) { IConnectionFactory factory = new ConnectionFactory("tcp://localhost:61616/"); using (IConnection connection = factory.CreateConnection()) { //Create the Session using (ISession session = connection.CreateSession()) { //Create the Producer for the topic/queue // IMessageProducer prod = session.CreateProducer(new Apache.NMS.ActiveMQ.Commands.ActiveMQTempQueue(message.NMSDestination)); IMessageProducer producer = session.CreateProducer(message.NMSDestination); // Create Response // IMessage response = session.CreateMessage(); ITextMessage response = producer.CreateTextMessage("Replied from VS2010 Test"); //response.NMSReplyTo = new Apache.NMS.ActiveMQ.Commands.ActiveMQQueue("testQ1"); response.NMSCorrelationID = message.NMSCorrelationID; if (message.NMSReplyTo != null) { producer.Send(message.NMSReplyTo, response); Console.WriteLine("Receive: " + ((ITextMessage)message).NMSCorrelationID); Console.WriteLine("Received from : " + message.NMSDestination.ToString()); Console.WriteLine("----------------------------------------------------"); } } } } Every time i tried to send a request to the listener, the response always send repeatedly. The first response will have NMSReplyTo properties while the other not. My workaround to stop this situation by cheking the NMSReplyTo properties if (message.NMSReplyTo != null) { producer.Send(message.NMSReplyTo, response); Console.WriteLine("Receive: " + ((ITextMessage)message).NMSCorrelationID); Console.WriteLine("Received from : " + message.NMSDestination.ToString()); Console.WriteLine("----------------------------------------------------"); } In my understanding, this happened because there was a circular send response in the listener to the same Queue. Could you guys help me how to fix this? Many Thanks, Chris

  • UIBarButtonItem: target-action not working?

    - by Jacob Relkin
    Hey fellas, I've got a custom view inside of a UIBarButtonItem, set by calling -initWithCustomView. OK, so the view renders fine, but when I tap it, it doesn't call the method that I set as the UIBarButtonItem's action property. Oh, and I have verified that my -deselectAll method works fine. Here's my code: UIImageView *SOCImageView = [[ UIImageView alloc ] initWithImage:[ UIImage imageNamed: @"cancel_wide.png" ] ]; SOItem.leftBarButtonItem = [[ UIBarButtonItem alloc ] initWithCustomView: SOCImageView ]; [ SOCImageView release ]; [ SOItem.leftBarButtonItem setTarget: self ]; [ SOItem.leftBarButtonItem setAction: @selector( deselectAll ) ]; Thanks a million

  • Introduction to 3D Graphics Programming

    - by Jacob Relkin
    Hi everyone! I'm a self-taught programmer with absolutely nil 3D programming experience. A client of mine has related to me an idea for an iPhone app that requires OpenGL ES 2.0 for it's inherently complex 3D structure and animations. Where do I start on this ( albeit long ) journey toward OpenGL ES competence? I'm willing to put in a tremendous amount of time and effort into learning, and if i could please get some pointers to where I should start and what to expect, that would be awesome!

  • emacs elisp buffer not running font lock mode until opened by user

    - by jacob
    My problem is I am opening a buffer using (set-buffer (find-tag-noselect (current-word))) and then I try to copy some text out of that buffer. The text that I get back has only the properties (fontified nil). find-tag-noselect automatically opens the buffer found in the TAGS file but it seems it does not run the font lock mode over it. When I manually switch to this buffer after it has been opened and then run the function again when it copies the text it has all the correct text properties attached. So what do I need to do to have this buffer completely initialized so that the correct syntax highlighting will be copied in?

  • noClassDefFoundError using Scala Plugin for Eclipse

    - by Jacob Lyles
    I successfully implemented and ran several Scala tutorials in Eclipse using the Scala plugin. Then suddenly I tried to compile and run an example, and this error came up: Exception in thread "main" java.lang.NoClassDefFoundError: hello/HelloWorld Caused by: java.lang.ClassNotFoundException: hello.HelloWorld at java.net.URLClassLoader$1.run(URLClassLoader.java:200) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at java.lang.ClassLoader.loadClass(ClassLoader.java:315) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:330) at java.lang.ClassLoader.loadClass(ClassLoader.java:250) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:398) After this point I could no longer run any Scala programs in Eclipse. I tried cleaning and rebuilding my project, closing and reopening my project, and closing and reopening Eclipse. Eclipse version number 3.5.2 and Scala plugin 2.8.0 Here is the original code: package hello object HelloWorld { def main(args: Array[String]){ println("hello world") } }

  • Cannot add Silverlight Maps Control to Windows Mobile 7 application

    - by Jacob
    I know the bits just came out today, but one of the first things I want to do with the newly released Windows Mobile 7 SDK is put a map up on the screen and mess around. I've downloaded the latest version of the Silverlight Maps Control and added the references to my application. As a matter of fact, the VS 2010 design view of the MainPage.xaml shows the map control after adding the namespace and placing the control. I'm using the provided VS 2010 Express version that comes with the Win Mobile 7 SDK and have just used the New Project - Windows Phone Application template. When I try to build I get two warnings related to the Microsoft.Maps.MapControl dll's. Warning 1 The primary reference "Microsoft.Maps.MapControl, Version=1.0.1.0, Culture=neutral, PublicKeyToken=498d0d22d7936b73, processorArchitecture=MSIL" could not be resolved because it has an indirect dependency on the framework assembly "System.Windows.Browser, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e" which could not be resolved in the currently targeted framework. "Silverlight,Version=v4.0,Profile=WindowsPhone". To resolve this problem, either remove the reference "Microsoft.Maps.MapControl, Version=1.0.1.0, Culture=neutral, PublicKeyToken=498d0d22d7936b73, processorArchitecture=MSIL" or retarget your application to a framework version which contains "System.Windows.Browser, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e". Warning 2 The primary reference "Microsoft.Maps.MapControl.Common, Version=1.0.1.0, Culture=neutral, PublicKeyToken=498d0d22d7936b73, processorArchitecture=MSIL" could not be resolved because it has an indirect dependency on the framework assembly "System.Windows.Browser, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e" which could not be resolved in the currently targeted framework. "Silverlight,Version=v4.0,Profile=WindowsPhone". To resolve this problem, either remove the reference "Microsoft.Maps.MapControl.Common, Version=1.0.1.0, Culture=neutral, PublicKeyToken=498d0d22d7936b73, processorArchitecture=MSIL" or retarget your application to a framework version which contains "System.Windows.Browser, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e". I'm leaning towards some way of adding the System.Windows.Browser to the targeted framework version. But I'm not even sure if that is possible. To be more specific; I'm looking for a way to get the Silverlight Maps Control up on a Windows Phone 7 series application. If possible. Thanks.

  • ClassCastException when casting custom View subclass

    - by Jens Jacob
    Hi I've run into an early problem with developing for android. I've made my own custom View (which works well). In the beginning i just added it to the layout programmatically, but i figured i could try putting it into the XML layout instead (for consistency). So what i got is this: main.xml: [...] <sailmeter.gui.CompassView android:id="@+id/compassview1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@id/widget55" android:background="@color/white" /> [...] CompassView.java: public class CompassView extends View { } SailMeter.java (activity class): public class SailMeter extends Activity implements PropertyChangeListener { public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); compassview = (CompassView) findViewById(R.id.compassview1); [...] } } (Theres obviously more, but you get the point) Now, this is the stacktrace: 05-23 16:32:01.991: ERROR/AndroidRuntime(10742): Uncaught handler: thread main exiting due to uncaught exception 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): java.lang.RuntimeException: Unable to start activity ComponentInfo{sailmeter.gui/sailmeter.gui.SailMeter}: java.lang.ClassCastException: android.view.View 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2596) 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2621) 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): at android.app.ActivityThread.access$2200(ActivityThread.java:126) 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1932) 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): at android.os.Handler.dispatchMessage(Handler.java:99) 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): at android.os.Looper.loop(Looper.java:123) 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): at android.app.ActivityThread.main(ActivityThread.java:4595) 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): at java.lang.reflect.Method.invokeNative(Native Method) 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): at java.lang.reflect.Method.invoke(Method.java:521) 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:860) 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:618) 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): at dalvik.system.NativeStart.main(Native Method) 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): Caused by: java.lang.ClassCastException: android.view.View 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): at sailmeter.gui.SailMeter.onCreate(SailMeter.java:51) 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1047) 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2544) 05-23 16:32:02.051: ERROR/AndroidRuntime(10742): ... 11 more Why cant i cast my custom view?

Thanks for any help.

  • iPhone smooth move and pinch of UIImageView

    - by Jacob
    I have an image view that I'm wanting to be able to move around, and pinch to stretch it. It's all working, but it's kinda jumpy when I start to do any pinch movements. The position will jump back and forth between the two fingers. - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { startLocation = [[touches anyObject] locationInView:mouth_handle]; if([touches count] == 2) { NSArray *twoTouches = [touches allObjects]; UITouch *first = [twoTouches objectAtIndex:0]; UITouch *second = [twoTouches objectAtIndex:1]; initialDistance = distanceBetweenPoints([first locationInView:mouth_handle],[second locationInView:mouth_handle]); } } - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { CGPoint pt = [[touches anyObject] locationInView:mouth_handle]; CGRect frame = [mouth_handle frame]; frame.origin.x += pt.x - startLocation.x; frame.origin.y += pt.y - startLocation.y; frame.origin.x = (frame.origin.x < 58) ? 58 : frame.origin.x; frame.origin.x = (frame.origin.x > (260 - mouth_handle.frame.size.width)) ?

  • Linq to NHibernate wrapper issue using where statement

    - by Jacob
    I'am using wrapper to get some data from table users IQueryable<StarGuestWrapper> WhereQuery = session.Linq<User>().Where(u => u.HomeClub.Id == clubId && u.IsActive).Select( u => new StarGuestWrapper() { FullName = u.Name + " " + u.LastName, LoginTime = DateTime.Now, MonthsAsMember = 2, StarRating = 1, UserPicture = u.Photo.PhotoData, InstructorFullName = "Someone Xyz", TalkInteractionDuringSession = true, GoalInteractionDuringSession = false }); I use this without a problem as a IQueryable so I can do useful things before actually running the query. Like : WhereQuery.Skip(startRowIndex).Take(maximumRows).ToList(); and so on. The problem occurs using 'where' statement on query. For example: WhereQuery.Where(s => s.StarRating == 1) will throw an exception in runtime that 'StarRating' doesn't exist in User table - of course it doesn't it's a wrappers property. I will work if I materialize query by WhereQuery.AsEnumerable().Where(s => s.StarRating == 1) but then it loses all the sens of using IQueryable and I don't want to do this. What is strange and interesting that not all properties from wrapper throw error, all the bool values can be used in where statement. Example : WhereQuery.Where(s => s.TalkInteractionDuringSession) It works in EntityFramework , why do I get this error in NHibernate and how to get it working the way I want it to ?

  • Template inheritence c++

    - by Chris Condy
    I have made a template singleton class, I have also made a data structure that is templated. My question is; how do I make my templated data structure inherit from a singleton so you can only have one float type of this structure? I have tested both seperate and have found no problems. Code provided under... (That is the problem) template <class Type> class AbstractRManagers : public Singleton<AbstractRManagers<Type> > The problem is the code above doesn't work I get alot of errors. I cant get it to no matter what I do template a templated singleton class...

  • ASP MVC Set RadioButton From Database

    - by Jacob Huggart
    Hello All, I have what should be an easy question for you today. I have two radio buttons in my view: Sex: <%=Html.RadioButton("Sex", "Male", true)% Male <%=Html.RadioButton("Sex", "Female", true)% Female I need to select one based on the value returned from my database. The way I am trying to do it now is: ViewData["Sex"] = data.Sex; //Set radio button But that is not working. I have tried every possible combination of isChecked properties. I know that data.Sex is returning either "Male" or "Female". What do I need to do to check the appropriate radio button?

  • Is Private Bytes >> Working Set normal?

    - by Jacob
    OK, this may sound weird, but here goes. There are 2 computers, A (Pentium D) and B (Quad Core) with almost the same amount of RAM running Windows XP. If I run the same code on both computers, the allocated private bytes in A never goes down resulting in a crash later on. In B it looks like the private bytes is constantly deallocated and everything looks fine. In both computers, the working set is deallocated and allocated similarly. Could this be an issue with manifests or DLLs (system)? I'm clueless. Also, I compiled the executable on A and ran it on B and it worked. Note: I observed the utilized memory with Process Explorer. Question: During execution (where we have several allocations and deallocations) is it normal for the number of private bytes to be much bigger (1.5 GB vs 70 MB) than the working set?

  • Custom validator not invoked when using Validation Application Block through configuration

    - by Chris
    I have set up a ruleset in my configuration file which has two validators, one of which is a built-in NotNullValidator, the other of which is a custom validator. The problem is that I see the NotNullValidator hit, but not my custom validator. The custom validator is being used to validate an Entity Framework entity object. I have used the debugger to confirm the NotNull is hit (I forced a failure condition so I saw it set an invalid result), but it never steps into the custom one. I am using MVC as the web app, so I defined the ruleset in a config file at that layer, but my custom validator is defined in another project. However, I wouldn't have thought that to be a problem because when I use the Enterprise Library Configuration tool inside Visual Studio 2008 it is able to set the type properly for the custom validator. As well, I believe the custom validator is fine as it builds ok, and the config tool can reference it properly. Does anybody have any ideas what the problem could be, or even what to do/try to debug further? Here is a stripped down version of my custom validator: [ConfigurationElementType(typeof(CustomValidatorData))] public sealed class UserAccountValidator : Validator { public UserAccountValidator(NameValueCollection attributes) : base(string.Empty, "User Account") { } protected override string DefaultMessageTemplate { get { throw new NotImplementedException(); } } protected override void DoValidate(object objectToValidate, object currentTarget, string key, ValidationResults results) { if (!currentTarget.GetType().Equals(typeof(UserAccount))) { throw new Exception(); } UserAccount userAccountToValidate = (UserAccount)currentTarget; // snipped code ... this.LogValidationResult(results, "The User Account is invalid", currentTarget, key); } } Here is the XML of my ruleset in Validation.config (the NotNull rule is only there to force a failure so I could see it getting hit, and it does): <validation> <type defaultRuleset="default" assemblyName="MyProj.Entities, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" name="MyProj.Entities.UserAccount"> <ruleset name="default"> <properties> <property name="HashedPassword"> <validator negated="true" messageTemplate="" messageTemplateResourceName="" messageTemplateResourceType="" tag="" type="Microsoft.Practices.EnterpriseLibrary.Validation.Validators.NotNullValidator, Microsoft.Practices.EnterpriseLibrary.Validation, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" name="Not Null Validator" /> </property> <property name="Property"> <validator messageTemplate="" messageTemplateResourceName="" messageTemplateResourceType="" tag="" type="MyProj.Entities.UserAccountValidator, MyProj.Entities, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" name="Custom Validator" /> </property> </properties> </ruleset> </type> </validation> And here is the stripped down version of the way I invoke the validation: var type = entity.GetType() var validator = ValidationFactory.CreateValidator(type, "default", new FileConfigurationSource("Validation.config")) var results = validator.Validate(entity) Any advice would be much appreciated! Thanks, Chris

  • WIX Installing an EXE after Msi install finishes.

    - by Chris
    Hi, I have created an MSI package which when finishes runs an exe. <Package InstallerVersion="200" Compressed="yes" /> <Media Id="1" Cabinet="media1.cab" EmbedCab="yes" /> <Directory Id="TARGETDIR" Name="SourceDir"> <Directory Id="ProgramFilesFolder"> <Directory Id="INSTALLLOCATION" Name="Installer Example"> <Component Id="VSTOR30.EXE" Guid="4fb0aee7-ec5b-4179-8938-a2be4df8ca0e"> <File Id="VSTOR30.EXE" Source="C:\Projects\InstallationTarget\ExampleInstaller\VSTOR30.EXE" KeyPath="yes" Checksum="yes" /> </Component> </Directory> </Directory> </Directory> <Feature Id="ProductFeature" Title="Installation Target" Level="1"> <ComponentRef Id="VSTOR30.EXE" /> </Feature> <InstallExecuteSequence> <Custom Action="RunEXE" After="InstallFinalize">NOT Installed</Custom> </InstallExecuteSequence> <CustomAction Id="RunEXE" FileKey="VSTOR30.EXE" ExeCommand="[#VSTOR30.EXE]" Execute="immediate" Return="asyncNoWait"> </CustomAction> <UI /> The MSI installs but the EXE is not run. I am calling it after Install Finalize and checking the install sequence in ORCA shows that it is being called at the correct time. I need deploy this through group policy software installation which uses a silent install without inputs. If i use a custom UI and run the EXE in the exit dialog <UI> <UIRef Id="WixUI_Minimal" /> <Publish Dialog="ExitDialog" Control="Finish" Event="DoAction" Value="LaunchApplication">WIXUI_EXITDIALOGOPTIONALCHECKBOX = 1 and NOT Installed</Publish> </UI> <Property Id="WIXUI_EXITDIALOGOPTIONALCHECKBOXTEXT" Value="RunEXE" /> <!-- Step 3: Include the custom action --> <Property Id="WixShellExecTarget" Value="[#VSTOR30.exe]" /> <CustomAction Id="RunEXE" BinaryKey="WixCA" DllEntry="WixShellExec" Impersonate="yes" /> Then i can install the software after the msi has finished running, however when putting this group policy the EXE doesn't install. Is there anything i am missing? Chris

  • Conditional Statement as Hierarchy jQuery

    - by Jacob Lowe
    Is there a way to make jQuery use objects in a conditional statement as an object in a hierarchy. For Example, I want to validate that something exist then tell it to do something just using the this selector. Like this if ($(".tnImg").length) { //i have to declare what object I am targeting here to get this to work $(this).animate({ opacity: 0.5, }, 200 ); } Is there a way to get jQuery to do this? I guess theres not a huge benefit but i still am curious

  • Does binarywriter.flush() also flush the underlying filestream object?

    - by jacob sebastian
    I have got a code snippet as follows: Dim fstream = new filestream(some file here) dim bwriter = new binarywriter(fstream) while not end of file read from source file bwriter.write() bwriter.flush() end while The question I have is the following. When I call bwriter.flush() does it also flush the fstream object? Or should I have to explicitly call fstream.flush() such as given in the following example: while not end of file read from source file bwriter.write() bwriter.flush() fstream.flush() end while A few people suggested that I need to call fstream.flush() explicitly to make sure that the data is written to the disk (or the device). However, my testing shows that the data is written to the disk as soon as I call flush() method on the bwriter object. Can some one confirm this?

  • Entity Framework mant to many insert

    - by Jacob
    I've been playing around with Entity Framework v2 and added some code to insert new entity with many to many relationship , lets say this entity is called meeting. I add hours to meeting : meeting.Hours.Add(hour); and I get different errors on different occasions On Update : Cannot insert the value NULL into column 'Meetings_Id', table 'Plan.dbo.MeetingHour'; column does not allow nulls. INSERT fails. The statement has been terminated. On Inset : An item with the same key has already been added. But the tricky party is that if I add this manually trough SQL Server Management Studio , I can update the entity with the same value , clearing it first (meeting.Hour.Clear()) Can't see what could be the problem , maybe entity model isn't mapped correctly ?

  • Comparing developer productivity tools

    - by Jacob
    I am getting ready to test developer productivity tools for our team (Coderush, Resharper, JustCode, etc). We're planning to roll the tool out the same time as we deploy Visual Studio 2010 and TFS. I've seen several posts discussing the merits of one tool versus another. However, I haven't been able to find any discussion of a methodology self evaluating. One approach I've seen is to use each tool for a month or so and decide which one you like best. This seems completely reasonable if I were evaluating it for myself, but since I'm evaluating for others as well, I'd like to do something more rigorous. I'm hoping to collect some ideas on how to do that. As a starting point, my thinking was to come up a list of 10-20 crucial features to compare, then prepare a matrix where I can compare the relative strengths of each product. Once the matrix is complete, we can make a well informed decision about which product aligns with out needs. Since I'm not a user of any product now, it's been difficult to figure out which features are critical and which are less so. Thank you!

  • How does one change the background color for a loading out-of-browser Silverlight 3 application?

    - by Jacob
    When running our Silverlight 3 application out-of-browser, startup takes a little time, but it's long enough to be noticeable. During this startup, the background of the window hosting the application displays an ugly white background color. When running in-browser, we have a splash screen, but that's loaded via JavaScript of course. How can I get a splash screen working for an out-of-browser Silverlight 3? Or if that's not possible, is there a way I can at least change the background color of the window?

  • using addListener with WordPress audio player

    - by Jacob
    Hi, I'm trying to add a listener for the stop event in the word press audio player but usage seems to be undocumented. I'm hoping someone who knows a little flash can look at the code and tell me how it works: In the code at http://tools.assembla.com/1pixelout/browser/audio-player/trunk/source/classes/Application.as I see a snippet with this: ExternalInterface.call("AudioPlayer.onStop", _options.playerID); I was hoping that would let me capture the event in javascript with ("player" is the ID of my player) AudioPlayer.addListener("player", "AudioPlayer.onStop", function() { alert('stopped'); }); But my javascript function never seems to get called

  • ClassNotFoundException when connecting to Mysql with JDBC

    I'm getting the following error when I try to run a simple Java JDBC program at the command line: Exception in thread "main" java.lang.NoClassDefFoundError: LoadDriver/java Caused by: java.lang.ClassNotFoundException: LoadDriver.java at java.net.URLClassLoader$1.run(URLClassLoader.java:200) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at java.lang.ClassLoader.loadClass(ClassLoader.java:315) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:330) at java.lang.ClassLoader.loadClass(ClassLoader.java:250) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:398) Here's the simple Java program, copied right out of the JDBC docs: import java.sql.Connection; import java.sql.DriverManager; import java.sql.SQLException; // Notice, do not import com.mysql.jdbc.* // or you will have problems! public class LoadDriver { public static void main(String[] args) { try { // The newInstance() call is a work around for some // broken Java implementations Class.forName("com.mysql.jdbc.Driver").newInstance(); } catch (Exception ex) { throw ex; // handle the error } } } Problem is, I'm bloody sure my bash shell $ClASSPATH variable is pointed at the correct .jar file. To be sure, I copied the JDBC .jar to the same directory as my program and ran it as follows: java -classpath ./mysql-connector-java-5.1.12-bin.jar LoadDriver.java I still get the same error. I'm running under Mac OSX, if it matters.

  • Suggestions for designing large-scale Java webapp from the group up

    - by Chris Thompson
    Hi all, I'm about to start developing a large-scale system and I'm struggling with which direction to proceed. I've done plenty of Java web apps before and I have plenty of experience with servlet containers and GWT and some experience with Spring. The problem is most of my webapps have been thrown together just to be a proof of concept and what I'm struggling with is what set of frameworks to use. I need to have both a browser based application as well as a web service designed to support access from mobile devices (Android and iPhone for now). Ideally, I'd like to design this system in such a way that I don't end up rewriting all of my servlets for each client (browser and phone) although I don't mind having some small checks in there to properly format the data. In addition, although I'm the only developer now, that won't necessarily be the case down the road and I'd like to design something that scales well both with regards to traffic and number of developers (isn't just a nightmare to maintain). So where I am now is planning on using GWT to design the browser-based interface but I'm struggling with how to reuse that code with to present the interface (most likely xml) for the mobile devices. Using GWT RPC would, I think, make it relatively easy to do all of the AJAX in the browser, but might make generating xml for the mobile phones difficult. In addition, I like the idea of using something like Hibernate for persistence and Spring Security to secure the whole thing. Again, I'm not sure how well those will cooperate with GWT (I think Hibernate should be fine...) There's obviously a lot more to this than I've presented here, but I've tried to give you the 5-minute overview. I'm a bit stumped and was wondering if anybody in the community had any experience starting from this place. Does what I'm trying to do make sense? Is it realistic? I have no doubt I can make all of these frameworks speak the same language, I'm just wondering if it's worth my time to fight with them. Also, am I missing a framework that would be really beneficial? Thanks in advance and sorry for the relatively broad question... Chris

  • Sparse constrained linear least-squares solver

    - by Jacob
    This great SO answer points to a good sparse solver, but I've got constraints on x (for Ax = b) such that each element in x is >=0 an <=N. The first thing which comes to mind is an QP solver for large sparse matrices. Also, A is huge (around 2e6x2e6) but very sparse with <=4 elements per row. Any ideas/recommendations? I'm looking for something like MATLAB's lsqlin but with huge sparse matrices.
