  • Adding a valuetype to IDL, compile and it fails with "No factory found"

    - by jim
    I can't figure out why the client keeps complaining about the not finding the factory method. I've tried the IDL with and without the "factory" keyword and that didn't change the behavior. The SDMGeoVT IDL matches other objects used (which run successfully). The SDMGeoVT classes generated match other generated classes in regards to inheritance and methods. The IDL is as follows; The idlj compiler runs w/o error. I implement the function on the server and I see the server code run and serialize the object over the wire (the server code runs fine). The client bombs with the following stack trace (the first couple of lines is from the jacORB library). I've created a small app just to compile and test the code (ArrayClient & ArrayServer). The base app (from the jacORB demo) works fine. I've tried using the base class OFBaseVT and a single object (SDMGeoVT vs the list return) and have the same issue. 2010-05-27 15:37:11.813 FINE read GIOP message of size 100 from ClientGIOPConnection to 127.0.0.1:47030 (1e4853f) 2010-05-27 15:37:11.813 FINE read GIOP message of size 100 from ClientGIOPConnection to 127.0.0.1:47030 (1e4853f) org.omg.CORBA.MARSHAL: No factory found for: IDL:pl/SDMGeoVT:1.0 at org.jacorb.orb.CDRInputStream.read_untyped_value(CDRInputStream.java:2906) at org.jacorb.orb.CDRInputStream.read_typed_value(CDRInputStream.java:3082) at org.jacorb.orb.CDRInputStream.read_value(CDRInputStream.java:2679) at com.helloworld.pl.SDMGeoVTHelper.read(SDMGeoVTHelper.java:106) at com.helloworld.pl.SDMGeoVTListHelper.read(SDMGeoVTListHelper.java:51) at com.helloworld.pl._PLManagerIFStub.getSDMGeos(_PLManagerIFStub.java:28) at com.helloworld.ArrayClient.<init>(ArrayClient.java:40) at com.helloworld.ArrayClient.main(ArrayClient.java:125) valuetype SDMGeoVT : common::OFBaseVT{ private string sdmName; private string zip; private string atz; private long long primaryDeptId; private string deptName; factory instance(in string name,in string ZIP,in string ATZ,in long long primaryDeptId,in string deptName,in string name); string getZIP(); void setZIP(in string ZIP); string getATZ(); void setATZ(in string ATZ); long long getPrimaryDeptId(); void setPrimaryDeptId(in long long primaryDeptId); string getDeptName(); void setDeptName(in string deptName); }; typedef sequence<SDMGeoVT> SDMGeoVTList; interface PLManagerIF : PublicManagerIF { pl::SDMGeoVTList getSDMGeos(in framework::ITransactionHandle tHandle, in long long productionLocationId); };

  • Getting timing consistency in Linux

    - by Jim Hunziker
    I can't seem to get a simple program (with lots of memory access) to achieve consistent timing in Linux. I'm using a 2.6 kernel, and the program is being run on a dual-core processor with realtime priority. I'm trying to disable cache effects by declaring the memory arrays as volatile. Below are the results and the program. What are some possible sources of the outliers? Results: Number of trials: 100 Range: 0.021732s to 0.085596s Average Time: 0.058094s Standard Deviation: 0.006944s Extreme Outliers (2 SDs away from mean): 7 Average Time, excluding extreme outliers: 0.059273s Program: #include <stdio.h> #include <stdlib.h> #include <math.h> #include <sched.h> #include <sys/time.h> #define NUM_POINTS 5000000 #define REPS 100 unsigned long long getTimestamp() { unsigned long long usecCount; struct timeval timeVal; gettimeofday(&timeVal, 0); usecCount = timeVal.tv_sec * (unsigned long long) 1000000; usecCount += timeVal.tv_usec; return (usecCount); } double convertTimestampToSecs(unsigned long long timestamp) { return (timestamp / (double) 1000000); } int main(int argc, char* argv[]) { unsigned long long start, stop; double times[REPS]; double sum = 0; double scale, avg, newavg, median; double stddev = 0; double maxval = -1.0, minval = 1000000.0; int i, j, freq, count; int outliers = 0; struct sched_param sparam; sched_getparam(getpid(), &sparam); sparam.sched_priority = sched_get_priority_max(SCHED_FIFO); sched_setscheduler(getpid(), SCHED_FIFO, &sparam); volatile float* data; volatile float* results; data = calloc(NUM_POINTS, sizeof(float)); results = calloc(NUM_POINTS, sizeof(float)); for (i = 0; i < REPS; ++i) { start = getTimestamp(); for (j = 0; j < NUM_POINTS; ++j) { results[j] = data[j]; } stop = getTimestamp(); times[i] = convertTimestampToSecs(stop-start); } free(data); free(results); for (i = 0; i < REPS; i++) { sum += times[i]; if (times[i] > maxval) maxval = times[i]; if (times[i] < minval) minval = times[i]; } avg = sum/REPS; for (i = 0; i < REPS; i++) stddev += (times[i] - avg)*(times[i] - avg); stddev /= REPS; stddev = sqrt(stddev); for (i = 0; i < REPS; i++) { if (times[i] > avg + 2*stddev || times[i] < avg - 2*stddev) { sum -= times[i]; outliers++; } } newavg = sum/(REPS-outliers); printf("Number of trials: %d\n", REPS); printf("Range: %fs to %fs\n", minval, maxval); printf("Average Time: %fs\n", avg); printf("Standard Deviation: %fs\n", stddev); printf("Extreme Outliers (2 SDs away from mean): %d\n", outliers); printf("Average Time, excluding extreme outliers: %fs\n", newavg); return 0; }

  • How can I get bitfields to arrange my bits in the right order?

    - by Jim Hunziker
    To begin with, the application in question is always going to be on the same processor, and the compiler is always gcc, so I'm not concerned about bitfields not being portable. gcc lays out bitfields such that the first listed field corresponds to least significant bit of a byte. So the following structure, with a=0, b=1, c=1, d=1, you get a byte of value e0. struct Bits { unsigned int a:5; unsigned int b:1; unsigned int c:1; unsigned int d:1; } __attribute__((__packed__)); (Actually, this is C++, so I'm talking about g++.) Now let's say I'd like a to be a six bit integer. Now, I can see why this won't work, but I coded the following structure: struct Bits2 { unsigned int a:6; unsigned int b:1; unsigned int c:1; unsigned int d:1; } __attribute__((__packed__)); Setting b, c, and d to 1, and a to 0 results in the following two bytes: c0 01 This isn't what I wanted. I was hoping to see this: e0 00 Is there any way to specify a structure that has three bits in the most significant bits of the first byte and six bits spanning the five least significant bits of the first byte and the most significant bit of the second? Please be aware that I have no control over where these bits are supposed to be laid out: it's a layout of bits that are defined by someone else's interface.

  • When is it appropriate to use error codes?

    - by Jim Hurne
    In languages that support exception objects (Java, C#), when is it appropriate to use error codes? Is the use of error codes ever appropriate in typical enterprise applications? Many well-known software systems employ error codes (and a corresponding error code reference). Some examples include operating systems (Windows), databases (Oracle, DB2), and middle-ware products (WebLogic, WebSphere). What benefits do error codes provide? What are the disadvantages to using error codes?

  • ASP.NET- using System.IO.File.Delete() to delete file(s) from directory inside wwwroot?

    - by Jim S
    Hello, I have a ASP.NET SOAP web service whose web method creates a PDF file, writes it to the "Download" directory of the applicaton, and returns the URL to the user. Code: //Create the map images (MapPrinter) and insert them on the PDF (PagePrinter). MemoryStream mstream = null; FileStream fs = null; try { //Create the memorystream storing the pdf created. mstream = pgPrinter.GenerateMapImage(); //Convert the memorystream to an array of bytes. byte[] byteArray = mstream.ToArray(); //return byteArray; //Save PDF file to site's Download folder with a unique name. System.Text.StringBuilder sb = new System.Text.StringBuilder(Global.PhysicalDownloadPath); sb.Append("\\"); string fileName = Guid.NewGuid().ToString() + ".pdf"; sb.Append(fileName); string filePath = sb.ToString(); fs = new FileStream(filePath, FileMode.CreateNew); fs.Write(byteArray, 0, byteArray.Length); string requestURI = this.Context.Request.Url.AbsoluteUri; string virtPath = requestURI.Remove(requestURI.IndexOf("Service.asmx")) + "Download/" + fileName; return virtPath; } catch (Exception ex) { throw new Exception("An error has occurred creating the map pdf.", ex); } finally { if (mstream != null) mstream.Close(); if (fs != null) fs.Close(); //Clean up resources if (pgPrinter != null) pgPrinter.Dispose(); } Then in the Global.asax file of the web service, I set up a Timer in the Application_Start event listener. In the Timer's ElapsedEvent listener I look for any files in the Download directory that are older than the Timer interval (for testing = 1 min., for deployment ~20 min.) and delete them. Code: //Interval to check for old files (milliseconds), also set to delete files older than now minus this interval. private static double deleteTimeInterval; private static System.Timers.Timer timer; //Physical path to Download folder. Everything in this folder will be checked for deletion. public static string PhysicalDownloadPath; void Application_Start(object sender, EventArgs e) { // Code that runs on application startup deleteTimeInterval = Convert.ToDouble(System.Configuration.ConfigurationManager.AppSettings["FileDeleteInterval"]); //Create timer with interval (milliseconds) whose elapse event will trigger the delete of old files //in the Download directory. timer = new System.Timers.Timer(deleteTimeInterval); timer.Enabled = true; timer.AutoReset = true; timer.Elapsed += new System.Timers.ElapsedEventHandler(OnTimedEvent); PhysicalDownloadPath = System.Web.Hosting.HostingEnvironment.ApplicationPhysicalPath + "Download"; } private static void OnTimedEvent(object source, System.Timers.ElapsedEventArgs e) { //Delete the files older than the time interval in the Download folder. var folder = new System.IO.DirectoryInfo(PhysicalDownloadPath); System.IO.FileInfo[] files = folder.GetFiles(); foreach (var file in files) { if (file.CreationTime < DateTime.Now.AddMilliseconds(-deleteTimeInterval)) { string path = PhysicalDownloadPath + "\\" + file.Name; System.IO.File.Delete(path); } } } This works perfectly, with one exception. When I publish the web service application to inetpub\wwwroot (Windows 7, IIS7) it does not delete the old files in the Download directory. The app works perfect when I publish to IIS from a physical directory not in wwwroot. Obviously, it seems IIS places some sort of lock on files in the web root. I have tested impersonating an admin user to run the app and it still does not work. Any tips on how to circumvent the lock programmatically when in wwwroot? The client will probably want the app published to the root directory. Thank you very much.

  • Error: The Side-by-Side configuration information in "BLAH.EXE" contains errors.

    - by Jim Buck
    This is the error Dependency Walker gives me on an executable that I am building with VC++ 2005 Express Edition. When trying to run the .exe, I get: This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem. (I am new to the manifest/SxS/etc. way of doing things post VC++ 2003.) EDIT: I am running on the same machine I am building the .exe with. In Event Viewer, I have the unhelpful: Faulting application blah.exe, version 0.0.0.0, faulting module blah.exe, version 0.0.0.0, fault address 0x004239b0.

  • MX Records - go to two servers?

    - by Jim Beam
    Right now I have a single mail server for IMAP. Let's say I want to introduce Exchange but not all users will be on it. Some users will be on my "legacy" IMAP, others on the "new" Exchange. Is it possible to "split up" your users (from the same e-mail domain) on two services like this? What would the MX records look like? My guess is that this isn't possible, but thought I'd ask. By the way, I realize that Exchange can offer IMAP and all that, but my question is more about splitting users across services and the MX records. The actual protocols above are only examples.

  • Creating a property setter delegate

    - by Jim C
    I have created methods for converting a property lambda to a delegate: public static Delegate MakeGetter<T>(Expression<Func<T>> propertyLambda) { var result = Expression.Lambda(propertyLambda.Body).Compile(); return result; } public static Delegate MakeSetter<T>(Expression<Action<T>> propertyLambda) { var result = Expression.Lambda(propertyLambda.Body).Compile(); return result; } These work: Delegate getter = MakeGetter(() => SomeClass.SomeProperty); object o = getter.DynamicInvoke(); Delegate getter = MakeGetter(() => someObject.SomeProperty); object o = getter.DynamicInvoke(); but these won't compile: Delegate setter = MakeSetter(() => SomeClass.SomeProperty); setter.DynamicInvoke(new object[]{propValue}); Delegate setter = MakeSetter(() => someObject.SomeProperty); setter.DynamicInvoke(new object[]{propValue}); The MakeSetter lines fail with "The type arguments cannot be inferred from the usage. Try specifying the type arguments explicitly." Is what I'm trying to do possible? Thanks in advance.

  • How do I unit test controllers for an asp.net mvc site that uses StructureMap and NHibernate?

    - by Jim Geurts
    I have an asp.net mvc2 application that is using StructureMap 2.6 and NHibernate 3.x. I would like to add unit tests to the application but am sort of at a loss for how to accomplish it. Say I have a basic controller called Posts that has an action called Index. The controller looks something like: public class PostsController : Controller { private readonly IPostService _postService; public PostsController(IPostService postService) { _postService = postService; } public ActionResult Index() { return View(_postService.QueryOver<Post>().Future()); } } If I wanted to create an nunit test that would verify that the index action is returning all of the posts, how do I go about that? If mocking is recommended, do you just assume that interaction with the database will work? Sorry for asking such a broad question, but my web searches haven't turned up anything decent for how to unit test asp.net mvc actions that use StructureMap (or any other IOC) and NHibernate. btw, if you don't like that I return a QueryOver object from my post service, pretend it is an IQueryable object. I'm using it essentially in the same way.

  • Is there a way to programatically popup the "Microsoft Silverlight Configuration" dialog?

    - by Jim McCurdy
    I am building for Silverlight 4, and I handle MouseRightButtonDown events and build my own ContextMenu's (a class from the Silverlight Toolkit). I would like to add the classic "Silverlight" menu item to my menus, and give the user the familiar option of launching the "Microsoft Silverlight Configuration" dialog. This is the dialog lets users manage Updates, Webcams, Permissions, and Application Storage. So I need a way to programatically launch the dialog when the menu item is clicked. I can be done for Flash, and it would seem that Microsoft would want to encourage developers to support that option. Can it be done?

  • xerces serialization in Java 6

    - by Jim Garrison
    In Java 6, the entire xerces XML parser/serializer implementation is now in the Java runtime (rt.jar). The packages have been moved under the com.sun.* namespace, which places them off-limits for explicit reference within client code. This is not a problem when using the parser, which is instantiated via javax API-defined factories. However, our code also uses xerces serialization (org.apache.xml.serialize.* ). AFAICT, there are no javax.xml API-defined factories for creating instances of Serializer and OutputFormat. This seems to imply that the only way to get one is to explicitly call the com.sun.org.apache.xml.serialize.* APIs. I've found the serialization classes in javax.xml.stream, but they don't seem to provide any output-formatting control like the xerces OutputFormat class. Question: Is there a way to access the xerces serialization functionality (which is in rt.jar) via a javax standard API, without including xerces.jar and also without explicitly instantiating com.sun.* classes? If not, is there an javax API-compliant way to achieve the same effect?

  • Ninject problem binding to constant value in MVC3 with a RavenDB session

    - by Jim
    I've seen a lot of different ways of configuring Ninject with ASP.NET MVC, but the implementation seems to change slightly with each release of the MVC framework. I'm trying to inject a RavenDB session into my repository. Here is what I have that's almost working. public class MvcApplication : NinjectHttpApplication { ... protected override void OnApplicationStarted() { base.OnApplicationStarted(); AreaRegistration.RegisterAllAreas(); RegisterGlobalFilters(GlobalFilters.Filters); RegisterRoutes(RouteTable.Routes); } protected override IKernel CreateKernel() { return new StandardKernel(new MyNinjectModule()); } public static IDocumentSession CurrentSession { get { return (IDocumentSession)HttpContext.Current.Items[RavenSessionKey]; } } ... } public class MyNinjectModule : NinjectModule { public override void Load() { Bind<IUserRepository>().To<UserRepository>(); Bind<IDocumentSession>().ToConstant(MvcApplication.CurrentSession); } } When it tries to resolve IDocumentSession, I get the following error. Error activating IDocumentSession using binding from IDocumentSession to constant value Provider returned null. Activation path: 3) Injection of dependency IDocumentSession into parameter documentSession of constructor of type UserRepository Any ideas on how to make the IDocumentSession resolve?

  • fileinfo and mime types I've never heard of

    - by Jim
    I'm not a stranger to mime types but this is strange. Normally, a text file would have been considered to be of text/plain mime but now, after implementing fileinfo, this type of file is now considered to be "text/x-pascal". I'm a little concerned because I need to be sure that I get the correct mime types set before allowing users to upload with it. Is there a cheat sheet that will give me all of the "common" mimes as they are interpreted by fileinfo? Sinan provided a link that lists all of the more common mimes. If you look at this list, you will see that a .txt file is of text/plain mime but in my case, a plain-jane text file is interpreted as text/pascal.

  • C# Application Becomes Slow and Unresponsive as String in Multiline Textbox Grows

    - by Jim Fell
    Hello. I have a C# application in which a LOT of information is being added to a Textbox for display to the user. Upon processing of the data, almost immediately, the application becomes very slow and unresponsive. This is how I am currently attempting to handle this: var saLines = textBox1.Lines; var saNewLines = saLines.Skip(50); textBox1.Lines = saNewLines.ToArray(); This code is run from a timer every 100mS. Is there a better way to handle this? I am using Microsoft Visual C# 2008 Express Edition. Thanks.

  • MVC 4 Beta with Mobile Project FIle Upload does not work

    - by Jim Shaffer
    I am playing around with the new MVC 4 beta release. I created a new web project using the Mobile Application template. I simply added a controller and a view to upload a file, but the file is always null in the action result. Is this a bug, or am I doing something wrong? Controller Code: using System.IO; using System.Web; using System.Web.Mvc; namespace MobileWebExample.Controllers { public class FileUploadController : Controller { public ActionResult Index() { return View(); } [AllowAnonymous] [HttpPost] [AcceptVerbs(HttpVerbs.Post)] public ActionResult Upload(HttpPostedFileBase file) { int i = Request.Files.Count; if (file != null) { if (file.ContentLength > 0) { var fileName = Path.GetFileName(file.FileName); var path = Path.Combine(Server.MapPath("~/App_Data/uploads"), fileName); file.SaveAs(path); } } return RedirectToAction("Index"); } } } And the view looks like this: @{ ViewBag.Title = "Index"; } <h2>Index</h2> <form action="@Url.Action("Upload")" method="post" enctype="multipart/form-data"> <label for="file">Filename:</label> <input type="file" name="file" id="file" /> <input type="submit" value="Submit" /> </form>

  • Auto-Complete Suggestions in Source Code Editor

    - by Jim
    Hello, Most IDEs (Eclipse, Netbeans, Intelij) provide contextually smart suggestions about the current statement you're writing. We would like to do the same thing (In Java for Java). We considered tokenizing the input and building our own abstract syntax trees, but quickly realized that could be a month long project in and of its self. We also started digging through the source code for the above mentioned IDEs, but it appears (correct me if I'm wrong) that the auto-complete code is pretty tightly woven with the rest of the IDE. We're wondering if anyone knows of a relatively isolated package that we could pull into our project to provide this auto-complete functionality. Thanks!
