• class weblogic.management.WeblogicMBean not found

  - by khue

  Hi all I meet this problem when I try to run Junit test case in fork mode (starting each test in a separate JVM) using Build ant file. [junit] Exception in thread "main" java.lang.NoClassDefFoundError: weblogic/management/WebLogicMBean [junit] at java.lang.ClassLoader.defineClass1(Native Method) [junit] at java.lang.ClassLoader.defineClass(ClassLoader.java:621) [junit] at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:124) [junit] at java.net.URLClassLoader.defineClass(URLClassLoader.java:260) [junit] at java.net.URLClassLoader.access$000(URLClassLoader.java:56) [junit] at java.net.URLClassLoader$1.run(URLClassLoader.java:195) [junit] at java.security.AccessController.doPrivileged(Native Method) [junit] at java.net.URLClassLoader.findClass(URLClassLoader.java:188) [junit] at java.lang.ClassLoader.loadClass(ClassLoader.java:307) [junit] at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) [junit] at java.lang.ClassLoader.loadClass(ClassLoader.java:252) [junit] at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:320) [junit] at java.lang.ClassLoader.defineClass1(Native Method) [junit] at java.lang.ClassLoader.defineClass(ClassLoader.java:621) [junit] at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:124) [junit] at java.net.URLClassLoader.defineClass(URLClassLoader.java:260) [junit] at java.net.URLClassLoader.access$000(URLClassLoader.java:56) [junit] at java.net.URLClassLoader$1.run(URLClassLoader.java:195) [junit] at java.security.AccessController.doPrivileged(Native Method) [junit] at java.net.URLClassLoader.findClass(URLClassLoader.java:188) [junit] at java.lang.ClassLoader.loadClass(ClassLoader.java:307) [junit] at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) [junit] at java.lang.ClassLoader.loadClass(ClassLoader.java:252) [junit] at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:320) [junit] at java.lang.ClassLoader.defineClass1(Native Method) [junit] at java.lang.ClassLoader.defineClass(ClassLoader.java:621) [junit] at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:124) [junit] at java.net.URLClassLoader.defineClass(URLClassLoader.java:260) [junit] at java.net.URLClassLoader.access$000(URLClassLoader.java:56) [junit] at java.net.URLClassLoader$1.run(URLClassLoader.java:195) .... I have the library weblogic.jar in my build library folders, which is set as classpath for the junit task. I look at this file and can't find the WeblogicMBean.class inside. However, in Jdev, I can import weblogic.management.WeblogicMBean into my class if I set library reference to this weblogic.jar file and compile my class without problem. Any suggestion of what really goes wrong? Thanks a lot.

• How to share session cookies between Internet Explorer and an ActiveX components hosted in a webpage

  - by jerem

  I am currently working on a .Net application which makes HTTP requests to some web applications hosted on a IIS server. The application is deployed through ClickOnce and is working fine on simple networks architectures. One of our customers has a very complex network involving a custom authentication server on which the user has first to log himself in order to be authenticated and get access to other applications on this network. Once authenticated on this server, a session cookie is created and sent to the user. Every time the user then makes a request on a secured server of the network, this cookie is checked to grant access to the user. If this cookie is not sent with the request, the user is redirected to the login page. The only browser used is Internet Explorer. This cookie cannot be accessed from our .net application since it is executed in another process than the Internet Explorer process which was used to log the user in, and thus is not sent with our requests, which cannot be completed since the server redirects every of our requests to the login page. I had a look at embedding my application into Internet Explorer by making the main control COM visible and creating it on an HTML page with an tag. It is working properly, however the sessions cookies set earlier in the browser are not sent when the ActiveX control makes web requests. I was hoping this sharing of the session information would be automatic (although I didn't really believe it). So my questions are : Is it possible to have access to this cookie in the embedded ActiveX? How? Does it make a difference to use a .Net COM-interop component instead of a "true" ActiveX control? Also, are there specific security words to describe this kind of behaviors (given that I am not an expert at all on security topics, this lack of proper terminology makes it a lot harder to find the needed resources)? My goal is to have my application's requests look the same from the requests made by the host browser's requests, and I thought that embedding the application as an ActiveX control into the browser was the only way to achieve this, however any suggestion on another to do this is welcome.

• EJB3 JNDI Lookup Failure in JEE application client

  - by Hank

  I'm trying to access an EJB3 from a JEE client-application, but keep getting nothing but lookup failures. My JEE Application 'CoreServer' is exposing a number of beans with remote interfaces. I have no problem accessing them from a Web Application deployed on the same Glassfish v3.0.1. Now I'm trying to access it from a client-application: public class Main { public static void main(String[] args) { CampaignControllerRemote bean = null; try { InitialContext ctx = new InitialContext(); bean = (CampaignControllerRemote) ctx.lookup("java:global/CoreServer/CampaignController"); } catch (Exception e) { System.out.println(e.getMessage()); } if (bean != null) { Campaign campaign = bean.get(361); if (campaign != null) { System.out.println("Got "+ campaign); } } } } When I run deploy it to Glassfish and run it from the appclient, I get this error: Lookup failed for 'java:global/CoreServer/CampaignController' in SerialContext targetHost=localhost,targetPort=3700,orb'sInitialHost=localhost,orb'sInitialPort=3700 However, that's exactly the same JNDI-name I use when I lookup the bean from the WebApplication (via SessionContext, not InitialContext - does that matter?). Also, when I deploy 'CoreServer', Glassfish reports: Portable JNDI names for EJB CampaignController : [java:global/CoreServer/CampaignController!mvs.api.CampaignControllerRemote, java:global/CoreServer/CampaignController] Glassfish-specific (Non-portable) JNDI names for EJB CampaignController : [mvs.api.CampaignControllerRemote, mvs.api.CampaignControllerRemote#mvs.api.CampaignControllerRemote] I tried all four names, none worked. Is the appclient unable to access beans with (only) Remote interfaces?

• EF4 querying from parent to grandchildren

  - by Hans Kesting

  I have a model withs Parents, Children and Grandchildren, in a many-to-many relationship. Using this article I created POCO classes that work fine, except for one thing I can't yet figure out. When I query the Parents or Children directly using LINQ, the SQL reflects the LINQ query (a .Count() executes a COUNT in the database and so on) - fine. The Parent class has a Children property, to access it's children. But (and now for the problem) this doesn't expose an IQueryable interface but an ICollection. So when I access the Children property on a particular parent all the Parent's Children are read. Even worse, when I access the Grandchildren (theParent.Children.SelectMany(child => child.GrandChildren).Count()) then for each and every child a separate request is issued to select all data of it's grandchildren. That's a lot of separate queries! Changing the type of the Children property from ICollection to IQueryable doesn't solve this. Apart from missing methods I need, like Add() and Remove(), EF just doesn't recognize the navigation property then. Are there correct ways (as in: low database interaction) of querying through children (and what are they)? Or is this just not possible?

• How to get current Joomla user with external PHP script

  - by Joey Adams

  I have a couple PHP scripts used for AJAX queries, but I want them to be able to operate under the umbrella of Joomla's authentication system. Is the following safe? Are there any unnecessary lines? joomla-auth.php (located in the same directory as Joomla's index.php): <?php define( '_JEXEC', 1 ); define('JPATH_BASE', dirname(__FILE__)); define( 'DS', DIRECTORY_SEPARATOR ); require_once ( JPATH_BASE .DS.'includes'.DS.'defines.php' ); require_once ( JPATH_BASE .DS.'includes'.DS.'framework.php' ); /* Create the Application */ $mainframe =& JFactory::getApplication('site'); /* Make sure we are logged in at all. */ if (JFactory::getUser()->id == 0) die("Access denied: login required."); ?> test.php: <?php include 'joomla-auth.php'; echo 'Logged in as "' . JFactory::getUser()->username . '"'; /* We then proceed to access things only the user of that name has access to. */ ?>

• Linq - how does it work??

  - by clarkeyboy

  Hey, I have just been looking into Linq with ASP.Net. It is very neat indeed. I was just wondering - how do all the classes get populated? I mean in ASP.Net, suppose you have a Linq file called Catalogue, and you then use a For loop to loop through Catalogue.Products and print each Product name. How do the details get stored? Does it just go through the Products table on page load and create another instance of class Product for each row, effectively copying an entire table into an array of class Product? If so, I think I have created a system very much like this, in the sense that there is a SiteContent module with an instance of each Manager class - for example there is UserManager, ProductManager, SettingManager and alike. UserManager contains an instance of the User class for each row in the Users table. They also contain methods such as Create, Update and Remove. These Managers and their "Items" are created on every page load. This just makes it nice and easy to access users, products, settings etc in every page as far as I, the developer, am concerned. Any any subsequent pages I need to create, I just need to reference SiteContent.UserManager to access a list of users, rather than executing a query from within that page (ie this method separates out data access from the workings of the page, in the same way as using code behind separates out the workings of the page from how the page is layed out). However the problem is that this technique seems rather slow. I mean it is effectively creating a database on every page load, taking data from another database. I have taken measures such as preventing, for example, the ProductManager from being created if it is not referenced on page load. Therefore it does not load data into storage when it is not needed. My question is basically whether my technique does the exact same thing as Linq, in the sense of duplicating data from tables into properties of classes.. Thanks in advance for any advice or answers about this. Regards, Richard Clarke

• IE History Tracking, IFRAMES, and Cross Domain error...

  - by peiklk

  So here's the deal. We have a Flash application that is running within an HTML file. For one page we call a legacy reporting system in ASP.NET that is within an IFRAME. This page then communicates back to the Flash application using cross-domain scripting (document.domain = "domain" is set in both pages. THIS ALL WORKS. Now the kicker. Flash has history tracking enabled. This loads the history.js file that created a div tag to store page changes so the back and forward buttons work in the browser. Which works for Firefox and Chrome as they create a div tag. HOWEVER In Internet Explorer, history.js creates another IFRAME (instead of a DIV) called ie_historyFrame. When the ScriptResource.axd code attempts to access this with: var frameDoc = this._historyFrame.contentWindow.document; we get an "Access is Denied" error message. ARGH! We've tried getting a handle to this IFRAME and inserting the document.domain code. FAIL. We've tried editing the historytemplate.html file that flex also uses to include document.domain... FAIL. I've tried to edit the underlying ASP.NET page to disable history tracking in the ScriptManager control. FAIL. At my wit's end on this one. We have users who need to use IE to access this site. They are big clients who we cannot tell to just use Firefox. Any suggestions would be greatly appreciated.

• Rails: Should partials be aware of instance variables?

  - by Alexandre

  Ryan Bates' nifty_scaffolding, for example, does this edit.html.erb <%= render :partial => 'form' %> new.html.erb <%= render :partial => 'form' %> _form.html.erb <%= form_for @some_object_defined_in_action %> That hidden state makes me feel uncomfortable, so I usually like to do this edit.html.erb <%= render :partial => 'form', :locals => { :object => @my_object } %> _form.html.erb <%= form_for object %> So which is better: a) having partials access instance variables or b) passing a partial all the variables it needs? I've been opting for b) as of late, but I did run into a little pickle: some_action.html.erb <% @dad.sons.each do |a_son| %> <%= render :partial => 'partial', :locals => { :son => a_son } %> <% end %> _partial.html.erb The son's name is <%= son.name %> The dad's name is <%= son.dad.name %> son.dad makes a database call to fetch the dad! So I would either have to access @dad, which would be going back to a) having partials access instance variables or I would have to pass @dad in locals, changing render :partial to <%= render :partial = 'partial', :locals = { :dad = @dad, :son = a_son } %, and for some reason passing a bunch of vars to my partial makes me feel uncomfortable. Maybe others feel this way as well. Hopefully that made some sense. Looking for some insight into this whole thing... Thanks!

• Practical value for concurrent-request-timeout parameter

  - by Andrei

  In the Seam Reference Guide, one can find this paragraph: We can set a sensible default for the concurrent request timeout (in ms) in components.xml: <core:manager concurrent-request-timeout="500" /> However, we found that 500 ms is not nearly enough time for most of the cases we had to deal with, especially with the severe restriction seam places on conversation access. In our application we have a combination of page scoped ajax requests (triggered by various use actions), some global scoped polling notification logic (part of the header, so included in every page) and regular links that invoke actions and/or navigate to other pages. Therefore, we get the dreaded concurrent access to conversation exception way too often, even without any significant load on the site. After researching the options for quite a bit, we ended up bumping this value to several seconds (we're debating whether to bump it up to 10s), as none of the recommended solutions seemed able to solve our issue completely (even forcing a global queue for all the ajax requests would still leave us exposed to a user deciding to click a link right when one of our polling calls was in progress). And we'd much rather have the users wait for a second or two instead of getting an error page just because they clicked a link at the wrong moment. And now to the question: is there something obvious we're missing (like a way to allow concurrent access to conversations and taking care of the needed locking ourselves, for instance :)? How do people solve this problem (ajax requests mixed with user driven interaction) in seam? Disabling all the links on the page while ajax requests are in progress (as suggested by one blog page) is really not a viable option. Any other suggestions? TIA, Andrei

• IPhone app with SSL client certs

  - by Pavel Georgiev

  I'm building an iphone app that needs to access a web service over https using client certificates. If I put the client cert (in pkcs12 format) in the app bundle, I'm able to load it into the app and make the https call (largely thanks to stackoverflow.com). However, I need a way to distribute the app without any certs and leave it to the user to provide his own certificate. I thought I would just do that by instructing the user to import the certificate in iphone's profiles (settings-general-profiles), which is what you get by opening a .p12 file in Mail.app and then I would access that item in my app. I would expect that the certificates in profiles are available through the keychain API, but I guess I'm wrong on that. 1) Is there a way to access a certificate that I've already loaded in iphone's profile in my app? 2) What other options I have for loading a user specified certificate in my app? The only thing I can come up with is providing some interface where the user can give an URL to his .p12 cerificate, which I can then load into the app's keychain for later use, but thats not exactly user-friednly. I'm looking for something that would allow the user to put the cert on phone (email it to himself) and then load it in my app.

• N-Tier Architecture - Structure with multiple projects in VB.NET

  - by focus.nz

  I would like some advice on the best approach to use in the following situation... I will have a Windows Application and a Web Application (presentation layers), these will both access a common business layer. The business layer will look at a configuration file to find the name of the dll (data layer) which it will create a reference to at runtime (is this the best approach?). The reason for creating the reference at runtime to the data access layer is because the application will interface with a different 3rd party accounting system depending on what the client is using. So I would have a separate data access layer to support each accounting system. These could be separate setup projects, each client would use one or the other, they wouldn't need to switch between the two. Projects: MyCompany.Common.dll - Contains interfaces, all other projects have a reference to this one. MyCompany.Windows.dll - Windows Forms Project, references MyCompany.Business.dll MyCompany.Web.dll - Website project, references MyCompany.Business.dll MyCompany.Busniess.dll - Business Layer, references MyCompany.Data.* (at runtime) MyCompany.Data.AccountingSys1.dll - Data layer for accounting system 1 MyCompany.Data.AccountingSys2.dll - Data layer for accounting system 2 The project MyCompany.Common.dll would contain all the interfaces, each other project would have a reference to this one. Public Interface ICompany ReadOnly Property Id() as Integer Property Name() as String Sub Save() End Interface Public Interface ICompanyFactory Function CreateCompany() as ICompany End Interface The project MyCompany.Data.AccountingSys1.dll and MyCompany.Data.AccountingSys2.dll would contain the classes like the following: Public Class Company Implements ICompany Protected _id As Integer Protected _name As String Public ReadOnly Property Id As Integer Implements MyCompany.Common.ICompany.Id Get Return _id End Get End Property Public Property Name As String Implements MyCompany.Common.ICompany.Name Get Return _name End Get Set(ByVal value as String) _name = value End Set End Property Public Sub Save() Implements MyCompany.Common.ICompany.Save Throw New NotImplementedException() End Sub End Class Public Class CompanyFactory Implements ICompanyFactory Public Function CreateCompany() As ICompany Implements MyCompany.Common.ICompanyFactory.CreateCompany Return New Company() End Function End Class The project MyCompany.Business.dll would provide the business rules and retrieve data form the data layer: Public Class Companies Public Shared Function CreateCompany() As ICompany Dim factory as New MyCompany.Data.CompanyFactory Return factory.CreateCompany() End Function End Class Any opinions/suggestions would be greatly appreciated.

• How can I make a server log file available via my ASP.NET MVC website?

  - by Gary McGill

  I have an ASP.NET MVC website that works in tandem with a Windows Service that processes file uploads. For easy maintenance of the site, I'd like the log file for the Windows Service to be accessible (to me, only) via the website, so that I can hit http://myserver/logs/myservice to view the contents of the log file. How can I do that? At a guess, I could either have the service write its log file in a "Logs" folder at the top level of the site, or I could leave it where it is and set up a virtual directory to point to it. Which of these is better - or is there another, better way? Wherever the file is stored, I can see that there's going to be another problem. I tried out the first option (Logs folder in my website), but when I try to access the file via HTTP I get an error: The process cannot access the file 'foo' because it is being used by another process. Now, I know from experience that my service keeps the file locked for writing while it's running, but that I can still open the file in Notepad to view the current contents. (I'm surprised that IIS insists on write access, if that's what's happening). How can I get around that? Do I really have to write a handler to read the file and serve it to the browser myself? Or can I fix this with configuration or somesuch? PS. I'm using IIS7 if that helps.

• Unhandled Exception with c++ app on Visual Studio 2008 release build - occurs when returning from fu

  - by Rich

  Hi, I have a (rather large) application that I have written in C++ and until recently it has been running fine outside of visual studio from the release build. However, now, whenever I run it it says "Unhandled exception at 0x77cf205b in myprog.exe: 0xC0000005: Access violation writing location 0x45000200.", and leads me to "crtexe.c" at line 582 ("mainret = main(argc, argv, envp);") if I attempt to debug it. Note that this problem never shows if I run my debug executable outside of visual studio, or if I run my debug or release build within visual studio. It only happens when running the release build outside of visual studio. I have been through and put plenty of printfs and a couple of while(1)s in it to see when it actually crashed, and found that the access violation occurs at exactly the point that the value is returned from the function (I'm returning a pointer to an object). I don't fully understand why I would get an access violation at the point it returns, and it doesn't seem to matter what I'm returning as it still occurs when I return 0. The point it started crashing was when I added a function which does a lot of reading from a file using ifstream. I am opening the stream every time I attempt to read a new file and close it when I finish reading it. If I keep attempting to run it, it will run once in about 20 tries. It seems a lot more reliable if I run it off my pen drive (it seems to crash the first 3 or 4 times then run fine after that - maybe it's due to its slower read speed). Thanks for your help, and if I've missed anything let me know.

• Importing MEF-Plugins into MVC Controllers

  - by Marks

  Hello. There are several examples of using MEF to plugin whole controller/view packages into a MVC application, but i didn't found one, using MEF to plugin funcional parts, used by other controllers. For example, think of a NewsService with a simple interface like interface INewsService { List<NewsItem> GetAllNews(); } That gets news wherever he wants, and returns them in a List of NewsItems. My page should load an exported INewsService and show the news on the page. But there is the problem. I cant just use [Import] in the controllers, as they are just created when they are needed. Edit: (Importing them to the main MVCApplication class doesn't work, becouse i cant access it from the controllers.) I think i found a way to access the main app via HttpContext.ApplicationInstance. But the Service object in this instance is null although it was created successfully in the Application_Start() method. Any idea why? So, how can i access the NewsService from within a controller? Thanks in advance, Marks

• Windows Programming: ID2D1Bitmap Interface - Getting the Bitmap Data

  - by LostInBrackets

  I've been writing my own library of functions to access some of the new Direct2D Windows libraries. In particular, I've been working on the ID2D1Bitmap interface. I wanted to write a function to return a pointer to the start of the bitmap data (for the editing of particular pixels, or custom encoding or whatever else I might wish for in the future). Unfortunately... problem ahead... I can't seem to find a way to get access to the raw pixel data from the ID2D1Bitmap Interface. Does anyone have an idea how to access this? One of my friends suggested drawing the bitmap to a surface and extracting the bitmap data from there. I don't know if this would work. It definitely seems inefficient and I wouldn't know which kind of surface to use. Any help is appreciated. (c++ in particular, but I assume the code won't be tooo different between languages) (I know I could just read in the data direct from the file, but I'm using the WIC decoders which means it could be in any number of indecipherable formats)

• Accessing XUL anonymous content using C++

  Hi All, I am writing Firefox extension using C++. I am trying to access XUL:tabox element in "TabOpen" event handler, but I am unable access any XUL element. I am putting here pseudocode of my extension for reference: HandleEvent() { if (event type is TabOpen) { nsCOMPtr<nsIDOMNode> OriginalNode = do_QueryInterface(event->GetTarget); nsCOMPtr<nsIDOMNodeList> childlist; // // Note here that I got OriginalNode's local name as "tabbrowser" // OriginalNode->GetChildNodes(getter_AddRefs(childlist)); PRUint32 len; childlist->GetLength(&len); // Return 1; consider only "popup" child element. nsString localName; nsCOMPtr<nsIDOMNode> node1; childlist->Item(0, getter_AddRefs(node1)); node1->GetLocalName(localName); // Returns "popup" as the local name. } } By traversing the DOM tree through DOM Inspector, I came to know that XUL elements are anonymous content. How do I access these XUL elements? Very Thanks in advance, Vaibhav.

• IRC Server configuration possibilities

  - by Katai

  I need to know a couple of things, concerning IRC servers that I couldnt directly find out over google (or werent clear enough for me to be sure if it actually works) I'm working at a larger community site, and wanted to deliver an in-page chat. Since it would be a nice feature to let people access it from outside too, over their own clients, I tought implementing an IRC Server would be the best solution (probably dedicated, I'll have to teach myself a couple of things for that) I plan to include a Web-based IRC client over an APE Client / Server. The problem is, I want to strip down the user rights, to disallow many functionalities that IRC would offer: Change of nicknames: The user logs in over the Page login, and I'll automatically create an IRC auth for this user with that password. So basically, he would connect to the IRC client over a button. And after connecting, he shouldnt be able to change his nickname at all Creating channels: I want the possibility to create channels, but not from 'normal' users. Basically, I would prefer to set up basic channels that are public, and if a user really creates an own channel, that one should be private and via invitation (is that possible?) Private conversations: private conversations should be filtered out from the allaround IRC client, into separate 'in-browser-windows' that I create over JS. I guess I just have to filter the stuff coming from IRC - or is there a better solution to that? Only 'registered' users have access: Like I said, if someone registers on the page, I would like to create an IRC 'account' for him. Users that arent registered on the page, cant access the IRC server at all (or get thrown out). Mainly to avoid spammers or bots from outside. Is this stuff solvable over IRC? I've read some FAQ's and Instructions for IRC OP's and servers, but I couldnt find a clear answer - it seems that everyone can do pretty much everything - I would like to configure it in a way that user possibilities are more cut down. Basically, giving users the possibility to chat, but not more. So the Question basically is, how possible / solvable this issues are allaround, or if I have to find other solutions for this.

  require "alien" --the address im trying to edit in the Mahjong game on Win7 local SCOREREF = 0x0744D554 --this should give me full access to the process local ACCESS = 0x001F0FFF --this is my process ID for my open window of Mahjong local PID = 1136 --function to open proc local op = alien.Kernel32.OpenProcess op:types{ ret = "pointer", abi = "stdcall"; "int", "int", "int"} --function to write to proc mem local wm = alien.Kernel32.WriteProcessMemory wm:types{ ret = "long", abi = "stdcall"; "pointer", "pointer", "pointer", "long", "pointer" } local pRef = op(ACCESS, true, PID) local buf = alien.buffer("99") -- ptr,uint32,byte arr (no idea what to make this),int, ptr print( wm( pRef, SCOREREF, buf, 4, nil)) --prints 1 if success, 0 if failed So that is my code. I am not even sure if I have the types set correctly. I am completely lost and need some guidance. I really wish there was more online help/documentation for alien, it confuses my poor brain. What utterly baffles me is that it WriteProcessMemory will sometimes complete successfully (though it does nothing at all, to my knowledge) and will also sometimes fail to complete successfully. As I've stated, my brain hurts. Any help appreciated.

• Accessing frame info in gdb

  - by Maelstrom

  In gdb, is there a way to access the contents of info frame in a script? I'm debugging a problem somewhere between Apache, PHP, APC and my own code, and I have about a hundred cores to choose from. Following the instructions here http://bugs.php.net/bugs-generating-backtrace.php I end up with a stacktrace like: #0 0x0121a31a in do_bind_function (opline=0xa94dd750, function_table=0x9b9cf98, compile_time=0 '\0') at /usr/src/debug/php-5.2.7/Zend/zend_compile.c:2407 #1 0x0124bb2e in ZEND_DECLARE_FUNCTION_SPEC_HANDLER (execute_data=0xbfef7990) at /usr/src/debug/php-5.2.7/Zend/zend_vm_execute.h:498 #2 0x01249dfa in execute (op_array=0xb79d5d3c) at /usr/src/debug/php-5.2.7/Zend/zend_vm_execute.h:92 #3 0x01261e31 in ZEND_INCLUDE_OR_EVAL_SPEC_VAR_HANDLER (execute_data=0xbfef80d0) at /usr/src/debug/php-5.2.7/Zend/zend_vm_execute.h:7809 #4 0x01249dfa in execute (op_array=0xb79d55ec) at /usr/src/debug/php-5.2.7/Zend/zend_vm_execute.h:92 ... #26 0x09caa894 in ?? () #27 0x00000000 in ?? () The stack will always look similar, with function execute and ZEND_something interleaved several times. I need to go up to the last instance of execute (up 2 in this case) and print myVar. Obviously gdb knows the function names, but does it surface them in any user variables I could access? Typing frame 2 shows a one-line version, and info frame shows a single stackframe in detail. I want to do something like while ($current_frame.function_name != "execute") {up;} print myVar but I don't see how to do it strictly within gdb. Is there a variable / structure / special memory location / something that allows access to gdb's information on either the whole stack (like bt) or to the current stack frame (like info frame)?

• SharePoint 2007 and SiteMinder

  - by pborovik

  Here is a question regarding some details how SiteMinder secures access to the SharePoint 2007. I've read a bunch of materials regarding this and have some picture for SharePoint 2010 FBA claims-based + SiteMinder security (can be wrong here, of course): SiteMinder is registered as a trusted identity provider for the SharePoint; It means (to my mind) that SharePoint has no need to go into all those user directories like AD, RDBMS or whatever to create a record for user being granted access to SharePoint - instead it consumes a claims-based id supplied by SiteMinder SiteMinder checks all requests to SharePoint resources and starts login sequence via SiteMinder if does not find required headers in the request (SMSESSION, etc.) SiteMinder creates a GenericIdentity with the user login name if headers are OK, so SharePoint recognizes the user as authenticated But in the case of SharePoint 2007 with FBA + SiteMinder, I cannot find an answer for questions like: Does SharePoint need to go to all those user directories like AD to know something about users (as SiteMinder is not in charge of providing user info like claims-based ids)? So, SharePoint admin should configure SharePoint FBA to talk to these sources? Let's say I'm talking to a Web Service of SharePoint protected by SiteMinder. Shall I make a Authentication.asmx-Login call to create a authentication ticket or this schema is somehow changed by the SiteMinder? If such call is needed, do I also need a SiteMinder authentication sequence? What prevents me from rewriting request headers (say, manually in Fiddler) before posting request to the SharePoint protected by SiteMinder to override its defence? Pity, but I do not have access to deployed SiteMinder + SharePoint, so need to investigate some question blindly. Thanks.

• Kohana 3 ORM: How to get data from pivot table? and all other tables for that matter

  - by zenna

  I am trying to use ORM to access data stored, in three mysql tables 'users', 'items', and a pivot table for the many-many relationship: 'user_item' I followed the guidance from http://stackoverflow.com/questions/1946357/kohana-3-orm-read-additional-columns-in-pivot-tables and tried $user = ORM::factory('user',1); $user->items->find_all(); $user_item = ORM::factory('user_item', array('user_id' => $user, 'item_id' => $user->items)); if ($user_item->loaded()) { foreach ($user_item as $pivot) { print_r($pivot); } } But I get the SQL error: "Unknown column 'user_item.id' in 'order clause' [ SELECT user_item.* FROM user_item WHERE user_id = '1' AND item_id = '' ORDER BY user_item.id ASC LIMIT 1 ]" Which is clearly erroneous because Kohana is trying to order the elements by a column which doesn't exist: user_item.id. This id doesnt exist because the primary keys of this pivot table are the foreign keys of the two other tables, 'users' and 'items'. Trying to use: $user_item = ORM::factory('user_item', array('user_id' => $user, 'item_id' => $user->items)) ->order_by('item_id', 'ASC'); Makes no difference, as it seems the order_by() or any sql queries are ignored if the second argument of the factory is given. Another obvious error with that query is that the item_id = '', when it should contain all the elements. So my question is how can I get access to the data stored in the pivot table, and actually how can I get access to the all items held by a particular user as I even had problems with that? Thanks

• Activate a python virtual environment using activate_this.py in a fabfile on Windows

  - by Rudy Lattae

  I have a Fabric task that needs to access the settings of my Django project. On Windows, I'm unable to install Fabric into the project's virtualenv (issues with Paramiko + pycrypto deps). However, I am able to install Fabric in my system-wide site-packages, no problem. I have installed Django into the project's virtualenv and I am able to use all the " python manage.py" commands easily when I activate the virtualenv with the "VIRTUALENV\Scripts\activate.bat" script. I have a fabric tasks file (fabfile.py) in my project that provides tasks for setup, test, deploy, etc. Some of the tasks in my fabfile need to access the settings of my django project through "from django.conf import settings". Since the only usable Fabric install I have is in my system-wide site-packages, I need to activate the virtualenv within my fabfile so django becomes available. To do this, I use the "activate_this" module of the project's virtualenv in order to have access to the project settings and such. Using "print sys.path" before and after I execute activate_this.py, I can tell the python path changes to point to the virtualenv for the project. However, I still cannot import django.conf.settings. I have been able to successfully do this on *nix (Ubuntu and CentOS) and in Cygwin. Do you use this setup/workflow on Windows? If so Can you help me figure out why this wont work on Windows or provide any tips and tricks to get around this issue? Thanks and Cheers. REF: http://virtualenv.openplans.org/#id9 | Using Virtualenv without bin/python Local development environment: Python 2.5.4 Virtualenv 1.4.6 Fabric 0.9.0 Pip 0.6.1 Django 1.1.1 Windows XP (SP3)
