• C# WCF - Failed to invoke the service.

  - by Keith Barrows

  I am getting the following error when trying to use the WCF Test Client to hit my new web service. What is weird is every once in awhile it will execute once then start popping this error. Failed to invoke the service. Possible causes: The service is offline or inaccessible; the client-side configuration does not match the proxy; the existing proxy is invalid. Refer to the stack trace for more detail. You can try to recover by starting a new proxy, restoring to default configuration, or refreshing the service. My code (interface): [ServiceContract(Namespace = "http://rivworks.com/Services/2010/04/19")] public interface ISync { [OperationContract] bool Execute(long ClientID); } My code (class): public class Sync : ISync { #region ISync Members bool ISync.Execute(long ClientID) { return model.Product(ClientID); } #endregion } My config (EDIT - posted entire serviceModel section): <system.serviceModel> <diagnostics performanceCounters="Default"> <messageLogging logMalformedMessages="true" logMessagesAtServiceLevel="true" logMessagesAtTransportLevel="true" /> </diagnostics> <serviceHostingEnvironment aspNetCompatibilityEnabled="false" /> <behaviors> <endpointBehaviors> <behavior name="JsonpServiceBehavior"> <webHttp /> </behavior> </endpointBehaviors> <serviceBehaviors> <behavior name="SimpleServiceBehavior"> <serviceMetadata httpGetEnabled="True" policyVersion="Policy15"/> </behavior> <behavior name="RivWorks.Web.Service.ServiceBehavior"> <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment --> <serviceMetadata httpGetEnabled="true"/> <!-- To receive exception details in faults for debugging purposes, set the value below to true.

• Jqgrid: navigation based on the selected row

  - by bsreekanth

  Hello, I was trying to enable navigation based on a selected row. So, the user select a row from jQgrid, and when press the show (is there a show button for the grid, I saw edit, add etc), it needs to go to a new page based on the url (part of the row). $(document).ready(function () { function getLink() { // var rowid = $("#customer_list").jqGrid('getGridParam', 'selrow'); var rowid = $("#customer_list").getGridParam('selrow'); var MyCellData = $("#customer_list").jqGrid('getCell', rowid, 'dataUrl'); return MyCellData; } $("#customer_list").jqGrid({ url:'mytestList', editurl:'jq_edit_test', datatype: "json", colNames:['Call Id','Title','dataUrl'], colModel:[ {name:'callId', width:80, search:false }, {name:'title', width:200, sortable:false }, {name:'dataUrl',hidden:true} ], rowNum:10, sortname:'lastUpdated', sortorder: 'desc', pager:'#customer_list_pager', viewrecords: true, gridview: true }).navGrid('#customer_list_pager', {add:true,edit:true,del:false,search:true,refresh:true}, {closeAfterEdit:true, afterSubmit:afterSubmitEvent }, // edit options {addCaption:'Create New something', afterSubmit:afterSubmitEvent, savekey:[true,13]}, // add options {afterSubmit:afterSubmitEvent} // delete options ); $("#customer_list").jqGrid('filterToolbar'); }); so, the url is passed for each row as dataUrl. I'm trying to read it and set to the button. Whn debug through firebug, the rowid was 223 (there were only 12 rows in the grid), and the cell value is empty. Currently the button is kept outside the grid, but it may better to be it part of the vavGrid thanks.

• iPhone UIScrollview with UIButtons - how to recreate springboard?

  - by Patrick

  I'm trying to create a springboard-like interface within my app. I'm trying to use UIButtons added to a UIScrollView. The problem I'm running in to is with the buttons not passing any touches to the UIScrollView - if I try to flick/slide and happen to press on the button it doesn't register for the UIScrollView, but if I flick the space between buttons it will work. The buttons do click/work if I touch them. Is there a property or setting that forces the button to send the touch events up to its parent (superview)? Do the buttons need to be added to something else before being added the UIScrollView? Here is my code: //init scrolling area UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 480, 480)]; scrollView.contentSize = CGSizeMake(480, 1000); scrollView.bounces = NO; scrollView.delaysContentTouches = NO; //create background image UIImageView *rowsBackground = [[UIImageView alloc] initWithImage:[self scaleAndRotateImage:[UIImage imageNamed:@"mylongbackground.png"]]]; rowsBackground.userInteractionEnabled = YES; //create button UIButton *btn = [[UIButton buttonWithType:UIButtonTypeCustom] retain]; btn.frame = CGRectMake(100, 850, 150, 150); btn.bounds = CGRectMake(0, 0, 150.0, 150.0); [btn setImage:[self scaleAndRotateImage:[UIImage imageNamed:@"basicbutton.png"]] forState:UIControlStateNormal]; [btn addTarget:self action:@selector(buttonClick) forControlEvents:UIControlEventTouchUpInside]; //add "stuff" to scrolling area [scrollView addSubview:rowsBackground]; [scrollView addSubview:btn]; //add scrolling area to cocos2d //this is just a UIWindow [[[Director sharedDirector] openGLView] addSubview:scrollView]; //mem-mgmt [rowsBackground release]; [btn release]; [scrollView release];

• Android-Java: Constructing a triangle based on Coordinates on a map and your bearing

  - by Aidan

  Hi Guys, I'm constructing a geolocation based application and I'm trying to figure out a way to make my application realise when a user is facing the direction of the given location (a particular long / lat co-ord). I've got the math figured, I just have the triangle to construct. //UPDATE So I've figured out a good bit of this... Below is a method which takes in a long / lat value and attempts to compute a triangle finding a point 700 meters away and one to its left + right. It'd then use these to construct the triangle. It computes the correct longitude but the latitude ends up somewhere off the coast of east Africa. (I'm in Ireland!). public void drawtri(double currlng,double currlat, double bearing){ bearing = (bearing < 0 ? -bearing : bearing); System.out.println("RUNNING THE DRAW TRIANGLE METHOD!!!!!"); System.out.println("CURRENT LNG" + currlng); System.out.println("CURRENT LAT" + currlat); System.out.println("CURRENT BEARING" + bearing); //Find point X(x,y) double distance = 0.7; //700 meters. double R = 6371.0; //The radius of the earth. //Finding X's y value. Math.toRadians(currlng); Math.toRadians(currlat); Math.toRadians(bearing); distance = distance/R; Global.Alat = Math.asin(Math.sin(currlat)*Math.cos(distance)+ Math.cos(currlat)*Math.sin(distance)*Math.cos(bearing)); System.out.println("CURRENT ALAT!!: " + Global.Alat); //Finding X's x value. Global.Alng = currlng + Math.atan2(Math.sin(bearing)*Math.sin(distance) *Math.cos(currlat), Math.cos(distance)-Math.sin(currlat)*Math.sin(Global.Alat)); Math.toDegrees(Global.Alat); Math.toDegrees(Global.Alng); //Co-ord of Point B(x,y) // Note: Lng = X axis, Lat = Y axis. Global.Blat = Global.Alat+ 00.007931; Global.Blng = Global.Alng; //Co-ord of Point C(x,y) Global.Clat = Global.Alat - 00.007931; Global.Clng = Global.Alng; } From debugging I've determined the problem lies with the computation of the latitude done here.. Global.Alat = Math.asin(Math.sin(currlat)*Math.cos(distance)+ Math.cos(currlat)*Math.sin(distance)*Math.cos(bearing)); I have no idea why though and don't know how to fix it. I got the formula from this site.. http://www.movable-type.co.uk/scripts/latlong.html It appears correct and I've tested multiple things... I've tried converting to Radians then post computations back to degrees, etc. etc. Anyone got any ideas how to fix this method so that it will map the triangle ONLY 700 meters in from my current location in the direction that I am facing? Thanks, EDIT/// Converting the outcome to radians gives me a lat of 5.6xxxxxxxxxxxxxx .I have a feeling this bug has something to do with conversions but its not THAT simple. The equation is correct, it just.. outputs wrong..

• F# Powerpack's Metadata doesn't recognize FSharp.Core as an F# library

  - by Nathan Sanders

  Here's my test code to isolate the problem: open Microsoft.FSharp.Metadata [<EntryPoint>] let main args = let core = FSharpAssembly.FromFile @"C:\Program Files\FSharp-2.0.0.0\\bin\FSharp.Core.dll" let core2 = FSharpAssembly.FSharpLibrary let core3 = System.AppDomain.CurrentDomain.GetAssemblies() |> Seq.find (fun a -> a.FullName.Contains "Core") |> FSharpAssembly.FromAssembly core.Entities |> Seq.iter (printfn "%A") 0 All three lets should give me the same FSharpAssembly. Instead, all 3 throw an exception that FSharp.Core is not an F# assembly (details below, re-formatted for readability). Two more clues: Using the core3 method, I get the same error for the test F# assembly itself I don't get the error at FSI after doing #r "@C:\Program Files...\FSharp.Powerpack.Metadata.dll". Any ideas? I'm using Visual Studio 2008, F# 2.0 and F# Powerpack 2.0.0.0 (May 20, 2010) release on an oldish XP VM, I think it's updated to SP3 though. (I got the error this morning with Powerpack 1.9.9.9, so I upgraded to 2.0.0.0. I thought that if 1.9.9.9 doesn't recognise F#'s 2.0.0.0's assemblies, then maybe bugfixes in Powerpack 2.0.0.0 would help.) Unhandled Exception: System.TypeInitializationException: The type initializer for 'Microsoft.FSharp.Metadata.AssemblyLoader' threw an exception. ---> System.TypeInitializationException: The type initializer for '<StartupCode$FSharp-PowerPack-Metadata>.$Metadata' threw an exception. ---> System.ArgumentException: could not produce an FSharpAssembly object for the assembly 'FSharp.Core' because this is not an F# assembly Parameter name: name at Microsoft.FSharp.Metadata.AssemblyLoader.Add(String name,Assembly assembly) at <StartupCode$FSharp-PowerPack-Metadata>.$Metadata..cctor() --- End of inner exception stack trace --- at Microsoft.FSharp.Metadata.AssemblyLoader..cctor() --- End of inner exception stack trace --- at Microsoft.FSharp.Metadata.AssemblyLoader.Get(Assembly assembly) at Microsoft.FSharp.Metadata.FSharpAssembly.FromAssembly(Assembly assembly) at Program.main(String[] args) in C:\Documents an...\FSMetadataTest\Program.fs:line 11 Press any key to continue . . .

• Python: how do I install SciPy on 64 bit Windows?

  - by Peter Mortensen

  How do I install SciPy on my system? Update 1: for the NumPy part (that SciPy depends on) there is actually an installer for 64 bit Windows: numpy-1.3.0.win-amd64-py2.6.msi (is direct download URL, 2310144 bytes). Running the SciPy superpack installer results in this message in a dialog box: "Cannot install. Python version 2.6 required, which was not found in the registry." I already have Python 2.6.2 installed (and a working Django installation in it), but I don't know about any Registry story. The registry entries seems to already exist: REGEDIT4 [HKEY_LOCAL_MACHINE\SOFTWARE\Python] [HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore] [HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore\2.6] [HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore\2.6\Help] [HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore\2.6\Help\Main Python Documentation] @="D:\\Python262\\Doc\\python262.chm" [HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore\2.6\InstallPath] @="D:\\Python262\\" [HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore\2.6\InstallPath\InstallGroup] @="Python 2.6" [HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore\2.6\Modules] [HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore\2.6\PythonPath] @="D:\\Python262\\Lib;D:\\Python262\\DLLs;D:\\Python262\\Lib\\lib-tk" What I have done so far: Step 1 Downloaded the NumPy superpack installer numpy-1.3.0rc2-win32-superpack-python2.6.exe (direct download URL, 4782592 bytes). Running this installer resulted in the same message, "Cannot install. Python version 2.6 required, which was not found in the registry.". Update: there is actually an installer for NumPy that works - see beginning of the question. Step 2 Tried to install NumPy in another way. Downloaded the zip package numpy-1.3.0rc2.zip (direct download URL, 2404011 bytes), extracted the zip file in a normal way to a temporary directory, D:\temp7\numpy-1.3.0rc2 (where setup.py and README.txt is). I then opened a command line window and: d: cd D:\temp7\numpy-1.3.0rc2 setup.py install This ran for a long time and also included use of cl.exe (part of Visual Studio). Here is a nearly 5000 lines long transcript (230 KB). This seemed to work. I can now do this in Python: import numpy as np np.random.random(10) with this result: array([ 0.35667511, 0.56099423, 0.38423629, 0.09733172, 0.81560421, 0.18813222, 0.10566666, 0.84968066, 0.79472597, 0.30997724]) Step 3 Downloaded the SciPy superpack installer, scipy-0.7.1rc3- win32-superpack-python2.6.exe (direct download URL, 45597175 bytes). Running this installer resulted in the message listed in the beginning Step 4 Tried to install SciPy in another way. Downloaded the zip package scipy-0.7.1rc3.zip (direct download URL, 5506562 bytes), extracted the zip file in a normal way to a temporary directory, D:\temp7\scipy-0.7.1 (where setup.py and README.txt is). I then opened a command line window and: d: cd D:\temp7\scipy-0.7.1 setup.py install This did not achieve much - here is a transcript (about 95 lines). And it fails: >>> import scipy as sp2 Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: No module named scipy Platform: Python 2.6.2 installed in directory D:\Python262, Windows XP 64 bit SP2, 8 GB RAM, Visual Studio 2008 Professional Edition installed.

• Android: trouble updating to Android SDK Tools, revision 7.

  - by Arhimed

  Currently I have Android SDK 2.1 (+ tools revision 4). I'd like to upgrade to Android SDK 2.2. When I try to do it I'm informed I need to upgrade Android SDK Tools to revision 7 first. So I agree, the process starts and then I get an error: -= warning! =- A folder failed to be renamed or moved. On Windows this typically means that a program Is using that Folder (for example Windows Explorer or your anti-virus software.) Please momentarily deactivate your anti-virus software. Please also close any running programs that may be accessing the directory 'D:\Install\Programming\android-sdk-working-dir\android-sdk_r04-windows\android-sdk-windows\too!s'. When ready, press YES to try again. Downloading Android SDK Tools, revision 7 Installing Android SDK Tools, revision 7 Failed to rename directory D:\Install\Programming\android-sdk-working-dir\android-sdk_r04-windows\android-sdk-windows\tools to D:\Install\Programming\android-sdk-working-dir\android-sdk_r04-windows\android-sdk-windows\temp\ToolPackage.old01. I am aware of http/https and antivirus issues. So I disactivated my AV. I also closed any application that might hold a handle to the folder. Eclipse is also closed (I start the manager via command line). However I still get the same error. Looks like the only app that can hold a handle to the folder is the manager itself, because its starting directory is the one the error complains about ('\tools'). I am on Win XP Pro + SP3. Does anyone have an idea?

• Kanban vs. Scrum

  - by Andrew Siemer

  Can someone with Kanban experience tell me how Kanban and Scrum differ? What are the pro's and con's of each of the different project management methodologies? Kanban seems to be getting a lot of press these days. I don't want to miss the hottest new way of tracking my teams failures (...and successes). Responses @S. Lott - What part of this article wasn't clear enough? infoq.com/articles/hiranabe-lean-agile-kanban/…. Do you have a more specific question? That is a great article but technically no it is not clear enough. That article gives a great amount of detail about kanban (and thank you for it...good read) but it does not specifically contrast Kanban vs. Scrum. That article will help someone like me make a decision but it most certainly won't help someone like my boss or in general someone less experienced! I was hoping for a quick overview of kanban pros and cons contrasted to scrum pros and cons. Thanks though! @S. Lott - Why do you say kanban vs. scrum? What leads you to conclude they are conflicting approaches? Can you make your question more specific? I don't think that they are necessarily conflicting. But they are different enough for a user to adhere to one over the other. Perhaps one fits a project or company better than the other? How would I sell one over the other when presenting a project management approach. Say I went to a company that was currently stuck in the rutt that is "water fall" - why would I sell one approach over the other?

• Making a app show inside a GUI in Java

  - by José

  Hello. I have one problem I've been dealing with for this week. You see, I'm new to Java, so that's probably it... Anyways, I've started a project out of pure curiosity. I had it done in Java, but in plain CMD-style, which is not very pretty. It calls one of my ten programs, chosen by the user using "Case". Eg.: If you type 1, it will go to program 1. After you finish it, it goes back to selection until the user press 0. After that, I've been trying to make a GUI for it. I've been able to create the selector alone and make it respond to the numbers chosen. If you press 1 and click ok, it will tell you you've chosen program 1. I, however, have not been able to make it run the program. I've been trying to make the program show up in a jPanel, part of the main GUI. I failed miserably. The program runs in separate but I can't make them run together like the CMD one. The apps were made in Eclipse SDK 3.5.2 The GUIs were made in Netbeans IDE 6.8 Here's the code for the GUI only (the prints are in PT-BR, my native language): Main program: /* * To change this template, choose Tools | Templates * and open the template in the editor. */ /* * ProgramasGUI.java * * Created on 31/01/2010, 22:56:19 */ package Main; import Main.Prog1; /** * * @author Zeh® */ public class ProgramasGUI extends javax.swing.JFrame { /** Creates new form ProgramasGUI */ public ProgramasGUI() { initComponents(); } /** This method is called from within the constructor to * initialize the form. * WARNING: Do NOT modify this code.

• IE8 CSS selector selects, but does not apply the style.

  - by Dan

  This is making me want to kill myself. I have some really simple CSS to style my input objects: input, button { border: 1px solid #c66600; background-color: white; color: #7d212f; font-family: "Eras Light ITC", Tahoma, sans; } But I don't like the ugly border it puts around radio buttons, so I use a selector to kill the border: input[type=radio] { border: none; } You can probably guess what browsers this works in and which ONE it does not work in. What's funny is when I press F12 to launch the excellent developer tools in IE8 it actually tells me that the style of the radio buttons has been overridden to 'none' just like I asked it to do, but the border remains on the radio button objects. I have tried a variety of semantic things, like setting the border width to 0px or the color to something insane like lime green, but it remains the originally assigned color that it got from the first style. And finally, I have tried only styling 'text' objects, in which case no style is applied to anything. Again, the browser claims to fulfill the CSS selection, but it visually does not happen. Thoughts? By the way, this is a DotNetNuke installation with generated code where I can't explicitly set the style of the radio buttons. Thanks, Dan

  I build Visual Studio 2008 setup Project with MSI build it depends on .NET 3.5. I added Prerequisites like: .NET 3.5, Microsoft office interoperability, VS tools for office System 3.0 Run time, .etc. After that Selected "Download Prerequisite from Same location as my application" in Specify install location for Prerequisite. Build the setup. I can find mysetup.msi in Release directory. In new Machine I started fresh installation of my application... While Clicking the mySetup.msi. Dialog shows like this " This Setup Requires .NET framework 3.5 , Please install .NET setup then run this setup, .NET Framework can be obtained from web Do you want to do that now?" it gives "yes" no option - if I press YES it goes microsoft website. How can avoid it ? I wanted setup take .NET Framework to be installed from same location where I put all setup files including mysetup.msi ? In case of Quite installation cmd /c "msiexec /package mysetup.msi /quiet /log install.log" ..in log I can see only half way through installtion then error Property(S): HideFatalErrorForm = TRUE MSI (s) (D0:24) [00:07:08:015]: Product: my product-- Installation failed. === Logging stopped: 3/23/2010 0:07:08 === so how can complete the installation without user intervention and without error using VS2008 setup project thanks for all the help in advance for any input.

• Marrying Core Animation with OpenGL ES

  - by Ole Begemann

  Edit: I suppose instead of the long explanation below I might also ask: Sending -setNeedsDisplay to an instance of CAEAGLLayer does not cause the layer to redraw (i.e., -drawInContext: is not called). Instead, I get this console message: <GLLayer: 0x4d500b0>: calling -display has no effect. Is there a way around this issue? Can I invoke -drawInContext: when -setNeedsDisplay is called? Long explanation below: I have an OpenGL scene that I would like to animate using Core Animation animations. Following the standard approach to animate custom properties in a CALayer, I created a subclass of CAEAGLLayer and defined a property sceneCenterPoint in it whose value should be animated. My layer also holds a reference to the OpenGL renderer: #import <UIKit/UIKit.h> #import <QuartzCore/QuartzCore.h> #import "ES2Renderer.h" @interface GLLayer : CAEAGLLayer { ES2Renderer *renderer; } @property (nonatomic, retain) ES2Renderer *renderer; @property (nonatomic, assign) CGPoint sceneCenterPoint; I then declare the property @dynamic to let CA create the accessors, override +needsDisplayForKey: and implement -drawInContext: to pass the current value of the sceneCenterPoint property to the renderer and ask it to render the scene: #import "GLLayer.h" @implementation GLLayer @synthesize renderer; @dynamic sceneCenterPoint; + (BOOL) needsDisplayForKey:(NSString *)key { if ([key isEqualToString:@"sceneCenterPoint"]) { return YES; } else { return [super needsDisplayForKey:key]; } } - (void) drawInContext:(CGContextRef)ctx { self.renderer.centerPoint = self.sceneCenterPoint; [self.renderer render]; } ... (If you have access to the WWDC 2009 session videos, you can review this technique in session 303 ("Animated Drawing")). Now, when I create an explicit animation for the layer on the keyPath @"sceneCenterPoint", Core Animation should calculate the interpolated values for the custom properties and call -drawInContext: for each step of the animation: - (IBAction)animateButtonTapped:(id)sender { CABasicAnimation *animation = [CABasicAnimation animationWithKeyPath:@"sceneCenterPoint"]; animation.duration = 1.0; animation.fromValue = [NSValue valueWithCGPoint:CGPointZero]; animation.toValue = [NSValue valueWithCGPoint:CGPointMake(1.0f, 1.0f)]; [self.glView.layer addAnimation:animation forKey:nil]; } At least that is what would happen for a normal CALayer subclass. When I subclass CAEAGLLayer, I get this output on the console for each step of the animation: 2010-12-21 13:59:22.180 CoreAnimationOpenGL[7496:207] <GLLayer: 0x4e0be20>: calling -display has no effect. 2010-12-21 13:59:22.198 CoreAnimationOpenGL[7496:207] <GLLayer: 0x4e0be20>: calling -display has no effect. 2010-12-21 13:59:22.216 CoreAnimationOpenGL[7496:207] <GLLayer: 0x4e0be20>: calling -display has no effect. 2010-12-21 13:59:22.233 CoreAnimationOpenGL[7496:207] <GLLayer: 0x4e0be20>: calling -display has no effect. ... So it seems that, possibly for performance reasons, for OpenGL layers, -drawInContext: is not getting called because these layers do not use the standard -display method to draw themselves. Can anybody confirm that? Is there a way around it? Or can I not use the technique I laid out above? This would mean I would have to implement the animations manually in the OpenGL renderer (which is possible but not as elegant IMO).

• Blackberry storm 9530 tracing touch events while scrolling

  hey in my screen there is a an edit field and 2 custom button fields as "OK" and "CANCEL" Below buttonfield there are some more focussable label fields when i write a name in edit field and press enter then focus comes to "OK" button but how to set focus on "CANCEL" button. Moreover while scrolling the focus does not automatically move ahead??? what to do may be i m confused with touch events and their handling!!! Kindly help!!!!!!!!!!!!

• android pending intent notification problem

  - by spagi

  Hi all! I have a alarm thing going on in my app and it launches a notification that then when pressed launched an activity. The problem is that when I create more than one alarm then the activity launched from the notification gets the same extras as the first one. I think the problem is either with the intent i put in the pending intent or in the pending intent itself. I think I might need to put a flag on one of these but I dont know which one. Intent showIntent =new Intent(context, notificationreceiver.class); showIntent.putExtra("details", alarmname); PendingIntent contentIntent = PendingIntent.getActivity(context, 0, showIntent, 0); notification.setLatestEventInfo(context, "The event is imminent", alarmname, contentIntent); And the receiver of the notification Bundle b = getIntent().getExtras(); String eventname = b.getString("details"); details.setText(eventname); The "details" extra is the same to every the next time a notification happens instead of having the different value. Until I set the intents I am sure that the correct value goes to the "details" so its a problem of getting the first intent everytime i press any notification. How can I make it to launch the correct intents? Hope I was as clear as i could Thanks!

• JMS messaging implementation

  - by Gandalf StormCrow

  I've been struggling with this "simple" task for more expirienced people, I'm stuck for 2 days now need help. I've changed things arround like zillion times now, finally I stumbled upon this spring JMS tutorial. What I want to do, Send a message and receive it. I've been also reading this book chapter 8 on messaging. It really nicely explains 2 type of messaging and there is nice example for publish-and-subscribe type but now example for point-to-point messaging( this is the one I need). I'm able to send message to the queue on my own, but don't have a clue how to receive thats why I tried with this spring tutorial here is what I've got so far : SENDER : package quartz.spring.com.example; import java.util.HashMap; import java.util.Map; import javax.jms.ConnectionFactory; import javax.jms.JMSException; import javax.jms.Message; import javax.jms.Queue; import javax.jms.Session; import org.springframework.jms.core.MessageCreator; import org.springframework.jms.core.JmsTemplate; import org.springframework.jms.core.JmsTemplate102; import org.springframework.jms.core.MessagePostProcessor; public class JmsQueueSender { private JmsTemplate jmsTemplate; private Queue queue; public void setConnectionFactory(ConnectionFactory cf) { this.jmsTemplate = new JmsTemplate102(cf, false); } public void setQueue(Queue queue) { this.queue = queue; } public void simpleSend() { this.jmsTemplate.send(this.queue, new MessageCreator() { public Message createMessage(Session session) throws JMSException { return session.createTextMessage("hello queue world"); } }); } public void sendWithConversion() { Map map = new HashMap(); map.put("Name", "Mark"); map.put("Age", new Integer(47)); jmsTemplate.convertAndSend("testQueue", map, new MessagePostProcessor() { public Message postProcessMessage(Message message) throws JMSException { message.setIntProperty("AccountID", 1234); message.setJMSCorrelationID("123-00001"); return message; } }); } } RECEIVER : package quartz.spring.com.example; import javax.jms.JMSException; import javax.jms.Message; import javax.jms.MessageListener; import javax.jms.TextMessage; public class ExampleListener implements MessageListener { public void onMessage(Message message) { if (message instanceof TextMessage) { try { System.out.println(((TextMessage) message).getText()); } catch (JMSException ex) { throw new RuntimeException(ex); } } else { throw new IllegalArgumentException("Message must be of type TextMessage"); } } } applicationcontext.xml <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jee="http://www.springframework.org/schema/jee" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-2.0.xsd"> <bean id="sender" class="quartz.spring.com.example.JmsQueueSender" init-method="sendWithConversion" /> <bean id="receiver" class="quartz.spring.com.example.ExampleListener" init-method="onMessage" /> </beans> Didn't really know that learning curve for this is so long, I mean the idea is very simple: Send message to the destination queue Receive message from the destination queue To receive messages, you do the following(so does book say): 1 Locate a ConnectionFactory, typically using JNDI. 2 Use the ConnectionFactory to create a Connection. 3 Use the Connection to create a Session. 4 Locate a Destination, typically using JNDI. 5 Use the Session to create a MessageConsumer for that Destination. Once you’ve done this, methods on the MessageConsumer enable you to either query the Destination for messages or to register for message notification. Can somebody please direct me towards right direction, is there a tutorial which explains in details how to receive message from the queue?I have the working send message code, didn't post it here because this post is too long as it is.

• Drools flow architecture, Drools flow events with AND join nodes

  - by Shoukry K

  I have been evaluating a number of frameworks including jBPM and Drools flow for my application requirements. Lots of the opinions seem to be inclined towards Drools flow as its more flexible, knowledge oriented, easier to integrate with business rules, etc.. The application is some sort of an Email Campaign manager , where different customers can sign in, prepare (design) and launch email campaigns. The application should be able to do the following : 1- Receive a list of email addresses, send emails to each of these addresses starting from a certain date and during a certain time interval of the day , do some custom actions, and then wait for reply emails. 2- If a reply email is received and depending on the response text of the email , and depending on the time the email was received certain actions need to happen, web service calls need to take place, and error handling for these calls. 3- The application will manage and run many and different campaigns (different customers and different flows for each customer) at any point of time. The first question is : Is Drools flow the way to go about this? My main concerns are scalability, suspending, resuming flows, and long wait, and flows management. As you see from the requirements : There is a scheduling part : Certain flows need to be run at a certain point in time, they need to get suspended and then resumed. For example start sending emails starting on Dec 1st 2010 and send emails only in the time interval between 08:00 and 17:00 GMT. By then it might be that all subscribers have been sent emails, but it might not be the case, the process needs to (resume) on Dec 2nd and send a second batch, however certain (users) already received emails and they should be able to (continue at different stages of the flow) There are long wait states : Days or even weeks , i need to persist, suspend / resume and terminate flows (manage flows) External Events : This is where i got stuck first, i tried to put together a simple flow (see attached screenshot) See image http://img46.imageshack.us/img46/9620/workflowwithevents.png , there is a start node , connected to an action node, connected to a join. An event node is connected to a second action node, which is connected to the join. The join is an AND join , after the join there is an action and the end node. Here is the sample code i am using to launch the flow : KnowledgeBuilder builder = KnowledgeBuilderFactory .newKnowledgeBuilder(); builder.add(ResourceFactory.newClassPathResource("campaign.rf", CampaignsDroolsPoc.class), ResourceType.DRF); if (builder.hasErrors()) { KnowledgeBuilderErrors errors = builder.getErrors(); Iterator<KnowledgeBuilderError> iterator = errors.iterator(); while (iterator.hasNext()) { System.out.println(iterator.next().toString()); } } KnowledgeBase base = KnowledgeBaseFactory.newKnowledgeBase(); base.addKnowledgePackages(builder.getKnowledgePackages()); final StatefulKnowledgeSession ksession = base .newStatefulKnowledgeSession(); // KnowledgeRuntimeLoggerFactory.newConsoleLogger(ksession); ksession.getWorkItemManager().registerWorkItemHandler("Log", new SendSMSWorkItemHandler()); ProcessInstance startProcess = ksession.startProcess("flow"); System.out.println("Signaling event"); startProcess.signalEvent("ev1", "ev1"); System.out.println("Signaled"); ksession.fireUntilHalt(); I am noticing that the event get triggered, the action node connected to the event gets triggered, however things seem to get stuck at the join. The flow does not continue past the AND join and the flow seems to get stuck. The action following the node does not get triggered. I also went through the drools flow documentation , and all the example codes, however i didn't find anything there. In addition any hints about the way to go about architecting the solution, and implementing it would be great.

• Eclipse throwing error when copying and pasting

• WPF DataGridTemplateColumn. Am I missing something?

  - by plotnick

  <data:DataGridTemplateColumn Header="Name"> <data:DataGridTemplateColumn.CellTemplate> <DataTemplate> <TextBlock Text="{Binding Name}"> </DataTemplate> </data:DataGridTemplateColumn.CellTemplate> <data:DataGridTemplateColumn.CellEditingTemplate> <DataTemplate> <TextBox Text="{Binding Name}"> </DataTemplate> </data:DataGridTemplateColumn.CellEditingTemplate> </data:DataGridTemplateColumn> It's clear example of Template column, right? What could be wrong with that? So, here is the thing - when a user navigates through DataGrid with hitting TAB-key, it needs to hit the TAB twice(!) to be able to edit text in TextBox. How could I make it editable as soon as the user gets the column focus, I mean even if he just starts typing? Ok. I found a way - into Grid.KeyUp() I put the code below: if (Grid.CurrentColumn.Header.ToString() == "UserName") { if (e.Key != Key.Escape) { Grid.BeginEdit(); // Simply send another TAB press if (Keyboard.FocusedElement is Microsoft.Windows.Controls.DataGridCell) { var keyEvt = new KeyEventArgs(Keyboard.PrimaryDevice, Keyboard.PrimaryDevice.ActiveSource, 0, Key.Tab) { RoutedEvent = Keyboard.KeyDownEvent }; InputManager.Current.ProcessInput(keyEvt); } } }

• Android addTextChangedListener onTextChanged not fired when Backspace is pressed?

  - by tsil

  I use addTextChangeListener to filter a list items. When the user enters a character on the editText, items are filtered based on user input. For example, if the user enters "stackoverflow", all items that contains "stackoverflow" are displayed. It works fine except that once the user press backspace to delete character(s), items are no longer filtered until he deletes all characters. For example, my items are: "stackoverflow 1", "stackoverflow 2", "stackoverflow 3", "stackoverflow 4". If user input is "stackoverflow", all items are displayed. If user input is "stackoverflow 1", only "stackoverflow 1" is displayed. Then user deletes the last 2 characters (1 and the space). User input is now "stackoverflow" but "stackoverflow 1" is still displayed and the other items are not displayed. This is my custom filter: private class ServiceFilter extends Filter { @Override protected FilterResults performFiltering(CharSequence constraint) { FilterResults results = new FilterResults(); if (constraint == null || constraint.length() == 0) { // No filter implemented we return all the list results.values = origServiceList; results.count = origServiceList.size(); } else { List<ServiceModel> nServiceList = new ArrayList<ServiceModel>(); for (ServiceModel s : serviceList) { if (s.getName().toLowerCase().contains(constraint.toString().toLowerCase())) { nServiceList.add(s); } } results.values = nServiceList; results.count = nServiceList.size(); } return results; } @Override protected void publishResults(CharSequence constraint, FilterResults results) { if (results.count == 0) { notifyDataSetInvalidated(); } else { serviceList = (List<ServiceModel>) results.values; notifyDataSetChanged(); } } } And how I handle text change event: inputSearch.addTextChangedListener(new TextWatcher() { @Override public void afterTextChanged(Editable arg0) { // TODO Auto-generated method stub } @Override public void beforeTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) { // TODO Auto-generated method stub } @Override public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) { if (cs.length() >= 1) { mAdapter.getFilter().filter(cs); } else { mAdapter = new ServiceAdapter(MyActivity.this, R.layout.ussd_list_item, serviceList); listView.setAdapter(mAdapter); } } });

• Using jquery pagination plugin

  - by eddy

  Hi. I want to use this plugin, but I don't know if it'll meet all of my requirements. I know I have to use JSON to fetch the data from the server and then use it at the client side, is that right?. For now, that's fine, because I only have very few records, but when I have thousands of ; will it be convenient to bring all the data at once? What I would like to know is : Is there any way to query the database every time I press the number of an specific page? I ask this cause I don't think is a good idea to load all the data in one go, is it? I used to pass the id of the record I was going to edit like this : <td align="center"> <c:url value="edititem.htm" var="url"> <c:param name="id" value="${item.id}"/> </c:url> <a href="<c:out value="${url}"/>"><img src="images/edit.png" width="14" height="14" alt="edit"/></a> </td> but now I don't know not how to do it. I really hope you can help me out. Thanks in advance.

• Why wont a simple socket to the localhost connect?

  - by Jake M

  I am following a tutorial that teaches me how to use win32 sockets(winsock2). I am attempting to create a simple socket that connects to the "localhost" but my program is failing when I attempt to connect to the local host(at the function connect()). Do I need admin privileges to connect to the localhost? Maybe thats why it fails? Maybe theres a problem with my code? I have tried the ports 8888 & 8000 & they both fail. Also if I change the port to 80 & connect to www.google.com I can connect BUT I get no response back. Is that because I haven't sent a HTTP request or am I meant to get some response back? Here's my code (with the includes removed): // Constants & Globals // typedef unsigned long IPNumber; // IP number typedef for IPv4 const int SOCK_VER = 2; const int SERVER_PORT = 8888; // 8888 SOCKET mSocket = INVALID_SOCKET; SOCKADDR_IN sockAddr = {0}; WSADATA wsaData; HOSTENT* hostent; int _tmain(int argc, _TCHAR* argv[]) { // Initialise winsock version 2.2 if (WSAStartup(MAKEWORD(SOCK_VER,2), &wsaData) != 0) { printf("Failed to initialise winsock\n"); WSACleanup(); system("PAUSE"); return 0; } if (LOBYTE(wsaData.wVersion) != SOCK_VER || HIBYTE(wsaData.wVersion) != 2) { printf("Failed to load the correct winsock version\n"); WSACleanup(); system("PAUSE"); return 0; } // Create socket mSocket = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP); if (mSocket == INVALID_SOCKET) { printf("Failed to create TCP socket\n"); WSACleanup(); system("PAUSE"); return 0; } // Get IP Address of website by the domain name, we do this by contacting(??) the Domain Name Server if ((hostent = gethostbyname("localhost")) == NULL) // "localhost" www.google.com { printf("Failed to resolve website name to an ip address\n"); WSACleanup(); system("PAUSE"); return 0; } sockAddr.sin_port = htons(SERVER_PORT); sockAddr.sin_family = AF_INET; sockAddr.sin_addr.S_un.S_addr = (*reinterpret_cast <IPNumber*> (hostent->h_addr_list[0])); // sockAddr.sin_addr.s_addr=*((unsigned long*)hostent->h_addr); // Can also do this // ERROR OCCURS ON NEXT LINE: Connect to server if (connect(mSocket, (SOCKADDR*)(&sockAddr), sizeof(sockAddr)) != 0) { printf("Failed to connect to server\n"); WSACleanup(); system("PAUSE"); return 0; } printf("Got to here\r\n"); // Display message from server char buffer[1000]; memset(buffer,0,999); int inDataLength=recv(mSocket,buffer,1000,0); printf("Response: %s\r\n", buffer); // Shutdown our socket shutdown(mSocket, SD_SEND); // Close our socket entirely closesocket(mSocket); // Cleanup Winsock WSACleanup(); system("pause"); return 0; }

• Struts2 - How to use the Struts2 Annotations?

  - by Aaron

  I'm trying to implement the Struts 2 Annotations in my project, but I don't know how. I added the convention-plugin v 2.1.8.1 to my pom I modified the web.xml ... <init-param> <param-name>actionPackages</param-name> <param-value>org.apache.struts.helloworld.action</param-value> </init-param> ... My Action package org.apache.struts.helloworld.action; import org.apache.struts.helloworld.model.MessageStore; import com.opensymphony.xwork2.ActionSupport; import org.apache.struts2.convention.annotation.Result; import org.apache.struts2.convention.annotation.Results; @Results({ @Result(name="success", location="HelloWorld.jsp") }) public class HelloWorld extends ActionSupport { public String execute() throws Exception { messageStore = new MessageStore() ; return SUCCESS; } The jsp page from where I'm trying to use my action. <body> <h1>Welcome To Struts 2!</h1> <p><a href="<s:url action='helloWorld'/>">Hello World</a></p> </body> When I press the link associated to the action helloWorld, but it's sends me to the exactly the same page. So, from index.jsp, it's sends to index.jsp. The way it should behave: it should send me to HelloWorld.jsp. I uploaded the project (a very simple HelloWorld app) to FileFront, maybe someone sees where is the problem. http://www.filefront.com/16364385/Hello_World.zip
