• Including a JSP Page Programatically

  - by Tom Tucker

  I need to include a JSP page in a Tag class. I believe the standard way to include a JSP page within another JSP page using API is this: request.getRequestDispatcher("included.jsp").include(request, response); However, I noticed that the included page is rendered at the top of the generated page, no matter where the code is located. On the other hand, the <jsp:include> action works as expected, rendering the included page where the tag appears in the JSP file. How do I include a JSP page in a class so that it behaves the same as the <jsp:include>? There's no way to invoke the <jsp:include> action within a Tag class, is there?

• Using Google AppEngine app as a OAuth provider

  - by Alistair

  Hi, I'm using the Google AppEngine 1.3.4 SDK which offers to allow your application to act as a OAuth service provider (http://code.google.com/appengine/docs/python/oauth/). Setting up a standard application on my localhost and using the following: Request URL /_ah/OAuthGetRequestToken Authorize URL /_ah/OAuthAuthorizeToken Access Token URL /_ah/OAuthGetAccessToken The client application just gets sent to a page requesting to grant OAuth access even though no user is logged in. Clicking 'Grant access' results in a message saying 'OAuth access granted' with no tokens or anything exchange. Can't see how this could work when it's not even prompting for a login. As this functionality is quite new I can't find much out there. I've created a OAuth provider before in Rails and know that you need a Consumer Key and Secret, something that seems to be lacking in GAE? Any ideas on how to get OAuth working in a sample GAE project are most welcome.

• How could the year 2010 be mistaken as a leap year? [closed]

  - by Templar

  According to news reports such as this one, older Playstation 3 game consoles incorrectly considered the year 2010 to be a leap year. The problem persisted through most of the Monday, March 1, which older PlayStations thought was Feb. 29, 2010, a date that doesn't exist. The standard leap year formula states that a leap year is any year that is divisible by 4, but not by 100, except if divisible by 400. The year 2010 doesn't fit any of those criteria. Any idea what programming error would have caused this?

• Howto format a date as localized Short MonthDay string

  - by Wouter

  I would like to format a DateTime to a string containing the month name abbreviated and the date for use in axislabels in a graph. The default DateTime format strings do not contain abbreviated month. I guess there is no standard but I could take a substring of the first 3 characters of the month name and replace this into the MonthDay format. The reason I would use MonthDay is that the ordering of month and date is locale dependent. Does anyone have a better idea? http://msdn.microsoft.com/en-us/library/az4se3k1.aspx#MonthDay

• Why does PuTTYcyg display â instead of hyphen in man pages?

  - by gbacon

  I've been using PuTTYcyg as a Cygwin terminal, but it doesn't render dashes in manual pages correctly. For example, the top of man gcc looks like GCC(1) GNU GCC(1) NAME gcc â GNU project C and C++ compiler SYNOPSIS gcc [âc|âS|âE] [âstd=standard] [âg] [âpg] [âOlevel] [âWwarn...] [âpedantic] [âIdir...] [âLdir...] [âDmacro[=defn]...] [âUmacro] [âfoption...] [âmmachineâoption...] [âo outfile] infile... Changing fonts doesn't help. How can I fix this?

• How to verify an XML digital signature in Cocoa?

  - by Geoff Smith

  I have a C# application that uses XML digital signatures to sign license files. I've used the standard Microsoft approach described here. I'm porting the application to the MAC and need to verify the signature. My general question is how best to do this? This is what I've done: I've used macport to install Aleksey's xmlsec1 library. Used the Chilkat library to convert my XML public key to a PEM file Chilkat.PublicKey pubKey = new Chilkat.PublicKey(); pubKey.LoadXml(publicKeyXml); pubKey.SaveOpenSslPemFile("publicKey.pem"); Compiled and ran the alekseys sample program. See (http://www.aleksey.com/xmlsec/api/xmlsec-verify-with-key.html) to verify an XML dsig. Result: my license files fail to validate. The call to xmlSecDSigCtxVerify fails with status=unknown. Now for my specific question: What can I do next? Geoff

• .NET custom form designer: How to implement IMenuCommandService?

  - by jonny

  I've got a report form designer written long ago for a database project. It used a lot of winapi magic hence i was forced to rewrite some parts 'in proper way'. Thanks to some articles from MSDN magazine (here and here) and CodeProject i was able to implement designer surface, toolbox and undo/redo engine. Every resource i discovered on the topic so far is a bit outdated. Can you point to fresh/comprehensive article? Code from article mentioned above seems not working. MenuCommandService.ShowContextMenu is called but nothing appears since there aren't any DesignerVerbs in globalVerbs collection. Should i add 'standard' ones, corresponded to designer actions such as cut/paste, manually? If yes, how can i accomplish this?

• Keycodes of function keys with F-lock off?

  - by ak

  Many recent keyboard from Microsoft and Logitech have a so-called F-Lock key, which toggles the function keys F1 to F12 between their traditional keycodes and new meanings that are printed onto the keys: F1=Help F2=Undo F3=Redo F4=Open ... . (See also http://en.wikipedia.org/wiki/F-Lock.) This means that long-established shortcuts such as Alt+F4 no longer work if the F-lock is off, and googling shows that quite a few people are unhappy about this. So I'm wondering, what virtual key (VK) codes do the function keys send when F-lock is off? VK_F13 to VK_F24 perhaps? Or do they not trigger standard keyboard events at all? (I haven't got such a keyboard to try and find out myself, and didn't manage to dig up anything on MSDN about this.)

• Automate open dialog box

  - by Andrey M.

  Is there any way to automate a opening files with open dialog box on Mac OS? The application asks user to open files with the standard open dialog box. But I need open files automatically. The idea is to write script or a small application which will click the button in the target application to open dialog box and then somehow select files which I needed. But I don't know how can I do it. Any suggestions will be very appreciated.

• What one-time-password devices are compatible with mod_authn_otp?

  - by netvope

  mod_authn_otp is an Apache web server module for two-factor authentication using one-time passwords (OTP) generated via the HOTP/OATH algorithm defined in RFC 4226. The developer's has listed only one compatible device (the Authenex's A-Key 3600) on their website. If a device is fully compliant with the standard, and it allows you to recover the token ID, it should work. However, without testing, it's hard to tell whether a device is fully compliant. Have you ever tried other devices (software or hardware) with mod_authn_otp (or other open source server-side OTP program)? If yes, please share your experience :)

• How can I find the program making a harmonica sound?

  - by Josh

  A friend has a Windows XP SP3 machine that plays a harmonica sound for about 5 seconds throughout the day at what seems to be random intervals (every couple hours). My question is how can I find the program making this sound? Is there a Windows API hook for monitoring audio access? I've gone through and checked all the standard Windows sounds in the Control Panel and right now the theme is set to no sounds and I personally checked to make sure none of the events have a sound specified. I also checked the Task Scheduler to make sure there wasn't something scheduled to go off every couple hours. Any ideas on how to go about finding the bugger?

• Can't authenticate with different NTLM credentials in one session with java.net.URLConnection

  - by ndn

  When I access a HTTP server using the standard Java API (java.net.URLConnection), the credentials are "cached" after the first successful authentication, and subsequent calls to Authenticator.setDefault() have no effect. So, I need to restart the application in order to use different credentials. I don't observe this effect when Basic Authentication is used. But I need to use NTLM for the server I'm accessing, and the Jakarta Commons HttpClient isn't an alternative either because it doesn't support NTLMv2 (see http://oaklandsoftware.com/papers/ntlm.html) Looking at the packets using Wireshark, I also observe that before the first successful authentication, an authentication with the current Windows credentials is attempted first. But after succesful authentication, only the saved credentials are used. Is there any way to reset or change the credentials java.net.Authenticator is using after a successful NTLM authentication?

• Is it possible to get an NSView to pass rightMouseDown: to the next responder without subclassing?

  - by Benedict Cohen

  I have a view which contains a few subviews: mainView subViewA subViewB SubViewC mainView is an NSView constructed from a nib and is controlled with an NSViewController subclass. The subviews are standard views such as NSTextField and NSImageView and are configured to be non-editable. I want mainView to receive rightMouseDown: even when the event is triggered in one of the subviews. The default implementation of rightMouseDown: in NSResponder passes the event to the next responder, but NSView changes the default behaviour and does not pass it to the next responder. I could subclass all of the subviews but this doesn't seem like a very elegant or maintainable solution. How can I get the subviews to pass rightMouseDown: messages to the next responder without subclassing all of the subviews?

• Problems with WiX and Visual Studio web deployment project

  - by Valeriu

  Hello, I want to create an .MSI package from a web deployment project in Visual Studio 2008. Now we want to use continuous integration and we would need the .MSI package build in the nightly builds. Till now we used standard Visual Studio Web Setup project, but this is not compatible with the MSBuild. So we decided to use WiX. The problem is that I have not found any good tutorial/documentation about this. Is there a way to do a WiX installer package from a web deployment project? If yes, how? Also, I tried to use heat.exe to create the XML for the WiX project .wxs file, but it seems that heat.exe doesn't recognize the web deployment project format. Thank you for your responses. Regards, V.

• Convert string to JSON using Python

  - by Luiz Fernando

  Hi, I'm a little bit confused with JSON in Python. To me, it seems like a dictionary, and for that reason I'm trying to do that: json = """{ "glossary": { "title": "example glossary", "GlossDiv": { "title": "S", "GlossList": { "GlossEntry": { "ID": "SGML", "SortAs": "SGML", "GlossTerm": "Standard Generalized Markup Language", "Acronym": "SGML", "Abbrev": "ISO 8879:1986", "GlossDef": { "para": "A meta-markup language, used to create markup languages such as DocBook.", "GlossSeeAlso": ["GML", "XML"] }, "GlossSee": "markup" } } } } } """ But when I do print dict(json), it gives an error. How can I transform this string into a structure and then call json["title"] to obtain "example glossary"? Thanks.

• How do I access a tomcat 5.5 installation via localhost running on Virtual PC 2007?

  - by MetroidFan2002

  I have a tomcat installation of 5.5 up and running on a Virtual PC with a fresh XP pro SP3. Launching tomcat gives the standard messages: INFO: Find registry server-registry.xml at classpath resource Apr 12, 2010 11:43:44 AM org.apache.catalina.startup.Catalina start INFO: Server startup in 3576 ms However, I cannot for the life of me connect to http://localhost:8080. I've also tried http://127.0.0.1:8080 with no success. This is on the virtual PC itself that I cannot connect to the server - I haven't bothered to try it on the host machine. Can anyone provide any information on why this may be happening? It's a fresh install of tomcat using Sun's JRE 5.0 (I know, EOL, technical requirements make me have to use 5.0 and not a newer JRE).

• QWidget keyPressEvent override

  - by eaigner

  Hi there, I'm trying for half an eternity now overriding QWidgets keyPressEvent function in QT but it just won't work. I've to say i am new to CPP, but I know ObjC and standard C. My problem looks like this: class QSGameBoard : public QWidget { Q_OBJECT public: QSGameBoard(QWidget *p, int w, int h, QGraphicsScene *s); signals: void keyCaught(QKeyEvent *e); protected: virtual void keyPressEvent(QKeyEvent *event); }; QSGameBoard is my QWidget subclass and i need to override the keyPressEvent and fire a SIGNAL on each event to notify some registered objects. My overridden keyPressEvent in QSGameBoard.cpp looks like this: void QSGameBoard::keyPressEvent(QKeyEvent *event) { printf("\nkey event in board: %i", event->key()); //emit keyCaught(event); } When i change QSGameBoard:: to QWidget:: it receives the events, but i cant emit the signal because the compiler complains about the scope. And if i write it like this the function doesn't get called at all. What's the problem here?

• Speed up compilation with mockito on Android

  - by pbreault

  I am currently developing an android app in eclipse using: One project for the app One project for the tests (Instrumentation and Pojo tests) In the test project, I am importing the mockito library for standard POJO testing. However, when I import the library, the compilation time skyrockets from 1 second to about 30 seconds in eclipse. The cause seems to be that the whole library is converted each time. So basically, each time a make a modification that I want to test, I have to wait 30 seconds. The only workarounds that I have found so far would be: Disable "Build Automatically" Create a project that includes only pojo tests and put mockito only there. Use another library that compiles faster (e.g. easymock) Any other suggestion?

• Is there "native" support for JSON in JDK6 Script Engine?

  - by Ayman

  I'm using JDK6the standard Scripting. I need to store and retrieve some JavaScript Objects that also contain Java Objects to JSON. I loaded the json2.js into the ScriptENgine and can use it fine without issue if the objects are all created in the Scrip Engine. The moment I try to use my own Java classes, I get some errors like "object does not support toJSON" errors. I did not find much about JSON in Java Scripting / Rhino context. Am I doing something totally wrong? What's the best way of achieving the requirement?

• Integrating virtual keyboard on a HP TouchSmart with an Adobe AIR app

  - by Alan

  Hi, Does anyone know if it's possible to integrate the ToushSmart's virtual keyboard with an Adobe AIR application? In most programs (Internet Explorer, Firefox, etc), when a user touches a text field a little keyboard icon automatically pops up which, when pressed, will bring up the virtual keyboard. However, this doesn't happen when clicking on text input fields in Adobe AIR applications. Has anyone had any experience working with AIR/Flash and touchscreens? Is there any API that can tell Windows (or the HP virtual keyboard specifically) that the user has clicked in a text field and that the virtual keyboard should be shown? The text fields are the standard kind (fl.controls.TextInput). Any suggestions would be greatly appreciated. Thanks in advance!

• WPF Control Templating: Keeping Windows look and feel

  - by Tyler

  I'm working on a control template for an inherited TextBox class. I'd like to use this template to add additional controls with the ScrollViewer. I can achieve that goal just fine, what I can't do recreate the border in such away that it matches the Windows look and feel. I have Windows Classic as my theme on XP. Textboxes are typically shown with the standard inset border style. With the XP Fischer Price theme, borders of textbox are a flat style and light blue. Is there any way of specifying something like this in the template? Ideally it would use the theme default (grey inset for Classic, flat and light blue for fischer price theme).

• jQuery event.stopPropagation is not working on <a>

  - by HorusKol

  I have the following javascript: $('#ge-display').click(function (event) { window.open('/googleearth/ge-display.php','','scrollbars=yes,menubar=no,height=650,width=1000,resizable=yes,toolbar=yes,location=no,status=no'); event.stopPropagation(); return false; }); the element with id 'ge-display' is a standard link: <a href="/googleearth/ge-display.php" id="ge-display" target="_blank">Load Google Earth Plugin (in a new window)</a> The problem is - when I take out the 'return false;' line from the click event handler, the javascript popup opens, and then another browser window opens - I thought stopPropagation() would prevent the links own click handler? I've also tried stopImmediatePropagation() - but I still need to return false to stop the default behaviour of the link.

• How do I get a TextBox to only accept numeric input in WPF?

  - by Giffyguy

  I'm looking to accept digits and the decimal point, but no sign. I've looked at samples using the NumericUpDown control for WinForms, and this sample of a NumericUpDown custom control from Microsoft. But so far it seems like NumericUpDown (supported by WPF or not) is not going to provide the functionality that I want. The way my app is designed, nobody in their right mind is going to want to mess with the arrows. They don't make any practical sense, in the context of my app. So I'm looking for a simple way to make a standard WPF TextBox accept only the characters that I want. Is this possible? Is it practical? Thanks, SO!

• Typical practice for redistributing third party source code with your source code

  - by bglenn

  I'm releasing an application I wrote as an open-source project by creating a public source-code repository. I use a third-party library which is also open-source and freely redistributable. I'm not versioning the third-party library, but should I include it in my repository for the convenience of those cloning the repository or should I expect them to download the third-party library on their own? To be clear, I'm not asking if I should version the third-party code or if I can redistribute it, but whether it is standard practice to include third-party source code as a convenience.

• LB_SETTABSTOPS does not appear to affect a CheckedListBox

  - by BP

  I am trying to set tab stops in a CheckedListBox in my WinForms application, but no matter what I do, it does not seem to have any effect. I have the following in the code for my form: <DllImport("user32.dll")> _ Public Sub SendMessage(ByVal hWnd As IntPtr, ByVal uMsg As Int32, ByVal wParam As Int32, ByRef lParam As Int32) End Sub Public Const LB_SETTABSTOPS As Int32 = &H192 And in the form's load method, I am doing the following, where theList is my CheckedListBox: Dim tabStops() As Integer = {40, 140, 240} Call SendMessage(theList.Handle, LB_SETTABSTOPS, tabStops.Length, tabStops(0)) theList.Refresh() And then later on, I use this in a loop, where col1 through col4 are all string values for the columns: theList.Items.Add(col1 & vbTab & col2 & vbTab & col3 & vbTab & col4) But no matter what I use for the values of tabStops, the list is formatted with standard width tab stops.
