  • How to call a WCF service using ksoap2 on android?

    - by Qing
    Hi all, Here is my code import org.ksoap2.*; import org.ksoap2.serialization.*; import org.ksoap2.transport.*; import android.app.Activity; import android.os.Bundle; import android.widget.TextView; public class ksop2test extends Activity { /** Called when the activity is first created. */ private static final String METHOD_NAME = "SayHello"; // private static final String METHOD_NAME = "HelloWorld"; private static final String NAMESPACE = "http://tempuri.org"; // private static final String NAMESPACE = "http://tempuri.org"; private static final String URL = "http://192.168.0.2:8080/HelloWCF/Service1.svc"; // private static final String URL = "http://192.168.0.2:8080/webservice1/Service1.asmx"; final String SOAP_ACTION = "http://tempuri.org/IService1/SayHello"; // final String SOAP_ACTION = "http://tempuri.org/HelloWorld"; TextView tv; StringBuilder sb; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); tv = new TextView(this); sb = new StringBuilder(); call(); tv.setText(sb.toString()); setContentView(tv); } public void call() { try { SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); request.addProperty("name", "Qing"); SoapSerializationEnvelope envelope = new SoapSerializationEnvelope( SoapEnvelope.VER11); envelope.dotNet = true; envelope.setOutputSoapObject(request); HttpTransportSE androidHttpTransport = new HttpTransportSE(URL); androidHttpTransport.call(SOAP_ACTION, envelope); sb.append(envelope.toString() + "\n");//cannot get the xml request send SoapPrimitive result = (SoapPrimitive)envelope.getResponse(); //to get the data String resultData = result.toString(); // 0 is the first object of data sb.append(resultData + "\n"); } catch (Exception e) { sb.append("Error:\n" + e.getMessage() + "\n"); } } } I can successfully access .asmx service, but when I try to call a wcf service the virtual machine said : Error: expected:END_TAG{http://schemas.xmlsoap.org/soap/envelope/}Body(position:END_TAG@1:712 in java.io.InputStreamReader@43ba6798 How to print what the request send?

  • Example WCF XML-RPC client C# code against custom XML-RPC server implementation?

    - by mr.b
    I have built my own little custom XML-RPC server, and since I'd like to keep things simple, on both server and client side (server side PHP runs, by the way), what I would like to accomplish is to create a simplest possible client in C# using WCF. Let's say that Contract for service exposed via XML-RPC is as follows. [ServiceContract] public interface IContract { [OperationContract(Action="Ping")] string Ping(); // server returns back string "Pong" [OperationContract(Action="Echo")] string Echo(string message); // server echoes back whatever message is } So, there are two example methods, one without any arguments, and another with simple string argument, both returning strings (just for sake of example). Service is exposed via http. What's next? Thanks for reading! P.S. I have done my homework of googling around for samples and similar, but all that I could come up with are some blog-related samples that use existing (and very big) classes, which implement correct IContract (or IBlogger) interfaces, so that most of what I am interested is hidden below several layers of abstraction...

  • Multiple Operations with soapAction="" in a WCF Service Contract?

    - by John Saunders
    I need to create a service that will be "called back" by a third party. As a result, I need to conform to their WSDL. Their WSDL has all of the operations defined with soapAction="", so my service needs to do the same. Unfortunately, I'm getting the error: The operations A and B have the same action (). Every operation must have a unique action value. In ASMX web services, there was a mode where the soapAction would not be used, but the name of the request element would be used instead. Is there some way using WCF not only to dispatch on the request element, but also to emit a WSDL with no soapAction?

  • Test data generators / quickest route to generating solid, non-repetitive, but not-real database sam

    - by Jamo
    I need to build a quick feasibility test / proof-of-concept of a remote database for a client, that will be populated with mostly-typical Company and People data (names, addresses, etc); 150K records or so. The sample databases mentioned here were helpful: http://stackoverflow.com/questions/57068/good-databases-with-sample-data ...but, I'd like to be able to generate sample data like this easily on less-typical datasets as well. Anyone have any recommendations for off-the-shelf (or off-the-web) solutions?

  • Resources related to data-mining and gaming on social networks

    - by darren
    Hi all I'm interested in the problem of patterning mining among players of social networking games. For example detecting cheaters of a game, given a company's user database. So far I have been following the usual recipe for a data mining project: construct a data warehouse that aggregates significant information select a classifier, and train it with a subsectio of records from the warehouse validate classifier with another test set lather, rinse, repeat Surprisingly, I've found very little in this area regarding literature, best practices, etc. I am hoping to crowdsource the information gathering problem here. Specifically what I'm looking for: What classifiers have worked will for this type of pattern mining (it seems highly temporal, users playing games, users receiving rewards, users transferring prizes etc). Are there any highly agreed upon attributes specific to social networking / gaming data? What is a practical amount of information that should be considered? One problem I've run into is data overload, where queries and data cleansing may take days to complete. Related to point above, what hardware resources are required to produce results? I've found it difficult to estimate the amount of computing power I will require for production use. It has become apparent that a white box in the corner does not have enough horse-power for such a project. Are companies generally resorting to cloud solutions? Are they buying clusters? Basically, any resources (theoretical, academic, or practical) about implementing a social networking / gaming pattern-mining program would be very much appreciated. Thanks.

  • How to fix "could not find a base address that matches schema http"... in WCF

    - by Craig Shearer
    I'm trying to deploy a WCF service to my server, hosted in IIS. Naturally it works on my machine :) But when I deploy it, I get the following error: This collection already contains an address with scheme http. There can be at most one address per scheme in this collection. Googling on this, I find that I have to put a serviceHostingEnvironment element into the web.config file: <serviceHostingEnvironment> <baseAddressPrefixFilters> <add prefix="http://mywebsiteurl"/> </baseAddressPrefixFilters> </serviceHostingEnvironment> But once I have done this, I get the following: Could not find a base address that matches scheme http for the endpoint with binding BasicHttpBinding. Registered base address schemes are [https]. It seems it doesn't know what the base address is, but how do I specify it? Here's the relevant section of my web.config file: <system.serviceModel> <serviceHostingEnvironment> <baseAddressPrefixFilters> <add prefix="http://mywebsiteurl"/> </baseAddressPrefixFilters> </serviceHostingEnvironment> <behaviors> <serviceBehaviors> <behavior name="WcfPortalBehavior"> <serviceMetadata httpGetEnabled="true"/> <serviceDebug includeExceptionDetailInFaults="true"/> </behavior> </serviceBehaviors> </behaviors> <bindings> <basicHttpBinding> <binding name="BasicHttpBinding_IWcfPortal" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" receiveTimeout="00:10:00" sendTimeout="00:10:00" openTimeout="00:10:00" closeTimeout="00:10:00"> <readerQuotas maxBytesPerRead="2147483647" maxArrayLength="2147483647" maxStringContentLength="2147483647"/> </binding> </basicHttpBinding> </bindings> <services> <service behaviorConfiguration="WcfPortalBehavior" name="Csla.Server.Hosts.Silverlight.WcfPortal"> <endpoint address="" binding="basicHttpBinding" contract="Csla.Server.Hosts.Silverlight.IWcfPortal" bindingConfiguration="BasicHttpBinding_IWcfPortal"> </endpoint> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/> </service> </services> </system.serviceModel> Can anybody shed some light on what's going on and how to fix it?

  • VBA-Sorting the data in a listbox, sort works but data in listbox not changed

    - by Mike Clemens
    A listbox is passed, the data placed in an array, the array is sort and then the data is placed back in the listbox. The part that does work is putting the data back in the listbox. Its like the listbox is being passed by value instead of by ref. Here's the sub that does the sort and the line of code that calls the sort sub. Private Sub SortListBox(ByRef LB As MSForms.ListBox) Dim First As Integer Dim Last As Integer Dim NumItems As Integer Dim i As Integer Dim j As Integer Dim Temp As String Dim TempArray() As Variant ReDim TempArray(LB.ListCount) First = LBound(TempArray) ' this works correctly Last = UBound(TempArray) - 1 ' this works correctly For i = First To Last TempArray(i) = LB.List(i) ' this works correctly Next i For i = First To Last For j = i + 1 To Last If TempArray(i) > TempArray(j) Then Temp = TempArray(j) TempArray(j) = TempArray(i) TempArray(i) = Temp End If Next j Next i ! data is now sorted LB.Clear ! this doesn't clear the items in the listbox For i = First To Last LB.AddItem TempArray(i) ! this doesn't work either Next i End Sub Private Sub InitializeForm() ' There's code here to put data in the list box Call SortListBox(FieldSelect.CompleteList) End Sub Thanks for your help.

  • Problem with core data migration mapping model

    - by dpratt
    I have an iphone app that uses Core Data to do storage. I have successfully deployed it, and now I'm working on the second version. I've run into a problem with the data model that will require a few very simple data transformations at the time that the persistent store gets upgraded, so I can't just use the default inferred mapping model. My object model is stored in an .xcdatamodeld bundle, with versions 1.0 and 1.1 next to each other. Version 1.1 is set as the active version. Everything works fine when I use the default migration behavior and set NSInferMappingModelAutomaticallyOption to YES. My sqlite storage gets upgraded from the 1.0 version of the model, and everything is good except for, of course, the few transformations I need done. As an additional experimental step, I added a new Mapping Model to the core data model bundle, and have made no changes to what xcode generated. When I run my app (with an older version of the data store), I get the following * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Object's persistent store is not reachable from this NSManagedObjectContext's coordinator' What am I doing wrong? Here's my code for to get the managed object model and the persistent store coordinator. - (NSPersistentStoreCoordinator *)persistentStoreCoordinator { if (_persistentStoreCoordinator != nil) { return _persistentStoreCoordinator; } _persistentStoreCoordinator = [[NSPersistentStoreCoordinator alloc] initWithManagedObjectModel:[self managedObjectModel]]; NSURL *storeUrl = [NSURL fileURLWithPath: [[self applicationDocumentsDirectory] stringByAppendingPathComponent: @"gti_store.sqlite"]]; NSError *error; NSDictionary *options = [NSDictionary dictionaryWithObjectsAndKeys: [NSNumber numberWithBool:YES], NSMigratePersistentStoresAutomaticallyOption, [NSNumber numberWithBool:YES], NSInferMappingModelAutomaticallyOption, nil]; if (![_persistentStoreCoordinator addPersistentStoreWithType:NSSQLiteStoreType configuration:nil URL:storeUrl options:options error:&error]) { NSLog(@"Eror creating persistent store coodinator - %@", [error localizedDescription]); } return _persistentStoreCoordinator; } - (NSManagedObjectModel *)managedObjectModel { if(_managedObjectModel == nil) { _managedObjectModel = [[NSManagedObjectModel mergedModelFromBundles:nil] retain]; NSDictionary *entities = [_managedObjectModel entitiesByName]; //add a sort descriptor to the 'Foo' fetched property so that it can have an ordering - you can't add these from the graphical core data modeler NSEntityDescription *entity = [entities objectForKey:@"Foo"]; NSFetchedPropertyDescription *fetchedProp = [[entity propertiesByName] objectForKey:@"orderedBar"]; NSSortDescriptor* sortDescriptor = [[[NSSortDescriptor alloc] initWithKey:@"index" ascending:YES] autorelease]; NSArray* sortDescriptors = [NSArray arrayWithObjects:sortDescriptor, nil]; [[fetchedProp fetchRequest] setSortDescriptors:sortDescriptors]; } return _managedObjectModel; }

  • Generic Data Structure Description Language

    - by Jon Purdy
    I am wondering whether there exists any declarative language for arbitrarily describing the format and semantics of a data structure, that can be compiled to a specific implementation of that structure in any of a set of target languages. That is, something like a generic data definition language but geared toward describing arbitrary data structures such as vectors, lists, trees, etc., and the semantics of operations on those structures. I ask because I had an idea for a feasible implementation of this concept, and I'm just wondering whether it's worth it, and, consequently, whether it's been done before. Another, slightly more abstract question: is there any real difference between the normative specification of a data structure (what it does) and its implementation (how it does it)?

  • How does cobol store and retrieve data?

    - by controlfreak123
    I'm starting to learn about COBOL. I have some experience writing programs that deal with sql databases and I guess I'm confused how cobol stores and retrieves data that is stored in a mainframe for example. I know that it's not like relational databases but every example program I've seen takes data straight from the command line and I know thats not how real world COBOL programs process the data. Can someone explain or show me a good resource that can explain it?

  • Visibility of Class field-data of Mouse Clicked ImageButton located within WrapPanel

    I am attempting to obtain the class-data behind an ImageButton that is mouse-clicked; which ImageButton is located within a WrapPanel filled with ImageButtons. The problem I am having is obtaining the visibility of the field data within the class behind the image-button. Although I can see the class, I can neither see nor access the field data.

  • Core Data vs. SQLitePersistentObjects

    - by Macatomy
    I'm creating an iPhone app and I'm trying to choose between 2 solutions for a persistent store. Core Data, or SQLitePersistentObjects. Basically, all my app needs is a way to store an array of model objects and then load them again to display in a UITableView. Its nothing too complicated. Core Data seems to have a much higher learning curve than the simple to use SQLitePersistentObjects. Are there any obvious benefits of using Core Data over SQLitePersistentObjects in my case?

  • Data Collection (Offline - no internet) and then syncing it to generate reports from server

    - by Nishant
    So, I have a new project I am planning on taking, and needed to know what skills will be required to achieve this project. The project is to do intensive data collection in the field where they don't have internet access. As part of the data collection, images will be uploaded as part of the data collection which will have to be resized, etc. Once the data collection occurs, this data needs to be consolidated and reported on. I am thinking there are two ways of generating the report. 1. Into a PDF that can be designed. 2. Is there a way to generate an executable file (since the PDF will be huge due to multiple images, etc) and the executable file is navigation friendly with drop-downs etc. It might not be an executable file, but could be a web page or some way that this can be delivered to the client in a friendly professional way. The PDF will have to be generated somehow so that it can be printed as a hard copy. What languages and skill sets will I need to accomplish this project?

  • Can Core Data be used on Linux?

    - by glenc
    This might be a stupid question, but I was wondering whether or not you can use the Core Data libraries on Linux at all? I'm planning how to build the server side of an iPhone app that I'm working on, and have found that you can use PyObjC to get access to Core Data in a Python environment, e.g. use Core Data in a TurboGears web application. At this point I'm thinking that you would have to run the web server on Mac OSX, because I can't find any evidence on the internet that you can access the Objective-C libraries on Linux. I've always written webapps on Linux but will obviously make the jump to an OSX server if it allows me to use the same datastore implementation on the iPhone and the server, the only job remaining being the Core Data <- Web Services XML translation that has to happen on the wire.

  • Parse and transform XML with missing elements into table structure

    - by dnlbrky
    I'm trying to parse an XML file. A simplified version of it looks like this: x <- '<grandparent><parent><child1>ABC123</child1><child2>1381956044</child2></parent><parent><child2>1397527137</child2></parent><parent><child3>4675</child3></parent><parent><child1>DEF456</child1><child3>3735</child3></parent><parent><child1/><child3>3735</child3></parent></grandparent>' library(XML) xmlRoot(xmlTreeParse(x)) ## <grandparent> ## <parent> ## <child1>ABC123</child1> ## <child2>1381956044</child2> ## </parent> ## <parent> ## <child2>1397527137</child2> ## </parent> ## <parent> ## <child3>4675</child3> ## </parent> ## <parent> ## <child1>DEF456</child1> ## <child3>3735</child3> ## </parent> ## <parent> ## <child1/> ## <child3>3735</child3> ## </parent> ## </grandparent> I'd like to transform the XML into a data.frame / data.table that looks like this: parent <- data.frame(child1=c("ABC123",NA,NA,"DEF456",NA), child2=c(1381956044, 1397527137, rep(NA, 3)), child3=c(rep(NA, 2), 4675, 3735, 3735)) parent ## child1 child2 child3 ## 1 ABC123 1381956044 NA ## 2 <NA> 1397527137 NA ## 3 <NA> NA 4675 ## 4 DEF456 NA 3735 ## 5 <NA> NA 3735 If each parent node always contained all of the possible elements ("child1", "child2", "child3", etc.), I could use xmlToList and unlist to flatten it, and then dcast to put it into a table. But the XML often has missing child elements. Here is an attempt with incorrect output: library(data.table) ## Flatten: dt <- as.data.table(unlist(xmlToList(x)), keep.rownames=T) setnames(dt, c("column", "value")) ## Add row numbers, but they're incorrect due to missing XML elements: dt[, row:=.SD[,.I], by=column][] column value row 1: parent.child1 ABC123 1 2: parent.child2 1381956044 1 3: parent.child2 1397527137 2 4: parent.child3 4675 1 5: parent.child1 DEF456 2 6: parent.child3 3735 2 7: parent.child3 3735 3 ## Reshape from long to wide, but some value are in the wrong row: dcast.data.table(dt, row~column, value.var="value", fill=NA) ## row parent.child1 parent.child2 parent.child3 ## 1: 1 ABC123 1381956044 4675 ## 2: 2 DEF456 1397527137 3735 ## 3: 3 NA NA 3735 I won't know ahead of time the names of the child elements, or the count of unique element names for children of the grandparent, so the answer should be flexible.

  • Selecting element by data attribute

    - by zizo
    Is there an easy and straight-forward method to select elements based on their data attribute? For example, select all anchors that has data attribute named customerID which has value of 22. I am kind of hesitant to use rel or other attributes to store such information, but I find it much harder to select an element based on what data is stored in it. Thanks!
