• How does java LoginContext.login() work?

  - by tangens

  I have this code to create a configuration of a java client to connect to a JBoss application server: System.setProperty( "java.security.auth.login.config", "auth.conf" ); LoginContext auth = new LoginContext( "myAuth", new LoginCallbackHandler( username, password ) ); auth.login(); The file auth.conf contains the following lines: myAuth { org.jboss.security.ClientLoginModule required; }; Now, somewhere else in the code (the LoginContext auth isn't known there) I have an EJB that does a initialContext.lookup( jndiName ) and a narrow() to access a Bean on the JBoss application server. This narrow only succeeds if the login information of the first step was correct. Question How does the login information propagate from the LoginContext to the narrow()? I don't see any connection between these two places. And further, how could I do two or more different logins inside of one client?

• In MS Access is there a way to allow forms to update while maintaning Read Only

  - by Alex

  I have several forms linked tables via queries. The form pull data such as sales and ratios by selecting a product from the main's form's combo box. I am however having to issues: 1- I would ultimately prefer the combo box to be a free entry; however by just entering in the box and hitting enter (not a button called “enter on a screen” which would initiate recalcs, just normal enter), while it does bring the new information in sub-forms it also changes the information in the original table. If I make the table read only that it just doesn't allow the form to work by saying that the table is read only. 2- The same Read only issue occurs when another user with read only rights tries to use the database. I understand that ready only is functioning as intended, however I am wondering if there is way to make some functions work while disallowing the updating. I am unfortunately learning on the go, so go easy plz. Thank you

• Multiple Table Joins to Improve Performance?

  - by EdenMachine

  If I have a table structure like this: Transaction [TransID, ...] Document [DocID, TransID, ...] Signer [SignerID, ...] Signature [SigID, DocID, SignerID, ...] And the business logic is like this: Transactions can have multiple documents Documents can have multiple signatures And the same signer can have multiple signatures in multiple documents within the same transaction So, now to my actual question: If I wanted to find all the documents in a particular transaction, would it be better, performance-wise, if I also stored the TransID and the DocID in the Signer table as well so I have smaller joins. Otherwise, I'd have to join through the Signature Document Transaction Documents to get all the documents in the transaction for that signer. I think it's really messy to have that many relationships in the Signer table though and it doesn't seem "correct" to do it that way (also seems like an update nightmare) but I can see that it might be better performance for direct joins. Thoughts? TIA!

• Map browser DOM using Javascript

  - by EddyR

  I'm trying to map a browsers DOM using javascript. It should list all the functions and attributes associated with it and it should also recurse through any object attributes. Now as I understand it 'window' is the most top-level node (although I've see a reference to 'top' as well in Chrome.) then 'document', etc. However I've never seen 'Node' under 'window' and yet I can call it. So where is 'Node' located? Is there a level above 'window' or is it a separate object (W3C says it's supposed to be inherited by 'document' only.)? I've been playing with a function to do this but I keep getting weird results so I'm not post it here. Alternatively - is it possible to get the properties from the object types instead of the object reference itself? for example 'DOMWindow' instead of 'window'. I think this would stop duplicating data from inherited objects.

• php and mysql user tracking and reporting

  - by inertiahz

  Hi, I currently have a table which consists of user information and lesson id; the table layout looks like: ---------------------------------------------------- |employeeID|numVisits|lessonID1|lessonID2|lessonID3| ---------------------------------------------------- |33388 |2 |1 |0 |3 | and a lessons table which contains the information about the lesson: ------------------------------------------------------ |lessonID |cateogry |title |filepath |numberviews| ------------------------------------------------------ |1 |beginner |lesson |file:// |10 | Within the lessonID fields in the user table is an integer which tracks how many times someone has clicked on a lesson. Now what I am trying to do is in a report I have the top 5 people who have visited the site and would like to then be able to drill down into what lessons they have clicked on. Can anyone help with this? Or would restructuring the way the database is be an easier task? Thanks

• gsub! Is modifying unspecified strings

  - by user335729

  I'm extracting some information from an XML file, and I want to perform some modifications on the data while keeping a copy of the original in a variable "origFile". This is what I have: require "rexml/document" include REXML doc = Document.new File.new(thePath) root = doc.root array = [] root.elements.each("dict/string") {|element| array << element} origFile = [] root.elements.each("dict"){|i| origFile << i} theBody = array[6][0].to_s theBody.gsub!(/\&lt;!-- more --\&gt;/, "----------Read More----------") The problem is that after I perform gsub! on theBody, origFile also has the modification. I don't understand why this would be or how to fix it. I would really appreciate your help.

• How can I tell what files are currently open by a process (i.e. my app)?

  - by chaiguy

  I am using a Lucene.Net index and want to give the user an option to move the index, but am having trouble closing it down so the directory/contents can be moved (I keep getting access denied exceptions). I need to be able to have some more information so I can debug this problem, such as being able to tell what files are currently open, and as much information about each use as possible. Alternatively, is there any way to simply force close a bunch of files so they can be moved? This would make things a lot easier to solve.

• Depmod - unresolved symbols in rt73 module

  - by Xolstice

  I'm trying to install a linux driver for my wireless network card (D-Link DWL-G510) on my Red Hat Linux 7.1 machine with a 2.4.37.9 kernel. I downloaded the serial monkey driver from the sourceforge site and was able to successfully compile the module. However, whenever I do a "make install", the make script executes a "depmod -a" command which then complains with the message: "Unresolved symbols in /lib/modules/2.4.37.9/extra/rt73.o". I then executed a "depmod -e" command to show unresolved symbols and it indicates the following information: request_firmware_Rsmp_38ce5074 release_firmware_Rsmp_33934162 I did a grep on the above information and it showed no source files making reference to it. I searched for it on google and it returned no results. Can anyone help?

• SVG Using Adobe in IE doesn't work when loading page, but saving the page and then loading it works.

  - by Nick

  So I'm trying to get a SVG document to load in IE. I can see it fine, but all calls to .getSVGDocument() fail, the svg onload="onload()" function never gets called and the right-click Adobe SVG Viewer context menu doesn't show up when right-clicking on the svg. It seems as though I'm managing to crash the adobe SVG viewer or something before it is able to call the onload function but after it has drawn the SVG document. As a test I saved the html page to my hard drive and loaded it up and walla - it works! Right-click, onload, and .getSVGDocument() all work. Very curious. For some reason getting the page from the server makes the adobe plugin crap out but loading up static HTML is fine. Any thoughts?

• How to write following MongoDB query in C# Driver?

  - by user3043457

  I wrote the exact query I need in Mongo console, but I'm having trouble rewriting it in C# driver. Here's a sample of the document, it's simple dictionary: { "_id" : ObjectId("539716bc101c588f941e2c27"), "_t" : "DictionaryDocument", "CsvSeparator" : ",", "SelectedAccounts" : "0", ... } Here's the query: db.settings.find({"SelectedAccounts" :{$exists:true}},{"SelectedAccounts":1, "_id":0} ) Now, I got the first part, Find with exists working, but how to write the second parameter in C# driver? I'd just like a single string as a result, not entire document. Here's C# code I got so far: _collection.FindOneAs(typeof(DictionaryDocument), Query.Exists(key)); key in this case is "SelectedAccounts". I'd like the query to filter and return only the data I need, I don't want to return all the results and search on the C# side. EDIT: I wouldn't mind if _id was passed back, but I don't need it. So only this part would work if it could be converted in C#: db.settings.find({"SelectedAccounts" :{$exists:true}},{"SelectedAccounts":1} )

• How to tell if running in a linux console versus an ssh session?

  - by Stéphane

  I have an application that needs to behave differently if run directly from the linux console. So if a user connects with SSH to run FooBar, or the user walks over to the console and logs in directly to run FooBar, I want it to do something different. What C API do I need to call to tell the difference between these two scenarios? I was thinking I'd have to look at the "tty/pts" information (such as what I see when I run "ps axf"), but I'm not certain if that is the best solution, nor what API to call to get that information. Hints appreciated. :)

• How to handle User Authentication for program in client’s local machine?

  - by Daniel

  Which user authentication scheme could be used at following scenario? 1.Application A developed by my company is installed at user's local computer. 2.Users login at my company's website. 3.If login is successful, access to the application A in user's local machine is granted. The development environment is .NET. Is there a secure way to authenticate the user to access the application? I've thought about encrypting the login information entered at the website, and then sending that information to the program at user's local machine for authentication. but I think as long as the client program has the decrypting ability, it is vulnerabe to decompiling,etc. Thanks in advance!

• C++ networking simple send and receive

  - by Wallter

  I'm trying to link 10 computers together, the program i would like to write would have one 'control' computer. From what I've looked up this computer would take all the packets sent over the network and do a echo with them... right? The other computers would need to be able to send information (then echoed to the others) to the 'control' ... is there a easy! or simple way to do this? From what I've seen i want a non-blocking socket? I have looked into sockets and such but for an armature programmer like me, this seems like a daunting task :) I'm kind-of looking for an easy class implication that has a send() and an event driven recv(). I'm not going to be sending that much information over the network.

• Retrieve text from external HTML/asp page with JavaScript

  - by Rotem

  Hi, I am using an external asp page (On the company's server - not related to me beside the fact that I'm using it for my job). The asp page has one query in it, I'm writing something in it and it gives me some information. In the information there is a certain line with constant header (let's assume 'HEADER'), I want to build an HTA that pulls the line that contains 'HEADER' to my HTA and display only this line. I think that this isn't possible without any server interaction, but I'm asking anyway. Can someone think of a way doing it? Thanks, Rotem

• Is this a correct iText design?

  - by Lucas

  I´m making some pdf reports to be used on a web app. I wonder if the way I´m taking to make the designs is appropriated. This would be a screenshot of the way I´m doing the things. As you can see, I´m using tables to position everything in the document. I think this is a pretty much similar design to HTML. But I want to know is there is a better way to get the same result I got. This is the document without cell borders: I could post the code if necessary. By the way, why should I spend long hours programming these kind of stuff with iText tool when I could do things faster and maybe better looking with iReport? I like iText, it´s just a question. Sorry for my english and thanks!

• jQuery: selecting by class after class change by .addClass() or .attr()

  - by Sosh

  I have some jQuery code something like this: $(document).ready(function() { $("img.off").click(function() { alert('on'); $(this).attr('class', 'on'); }); $("img.on").click(function() { alert('off'); $(this).attr('class', 'off'); }); }); The selector works fine for images that have the class name defined in the original HTML document, however after manipulating the class name with jQuery, the img item will not respond to selectors using it's new class. In other words, running the above code, if you click an 'off' img, it will trigger the first function, and change the class to 'on'. However, clicking this image again does not trigger the second function (as I would have expected), but rather triggers the first again. It's as if the selector is reading the old DOM rather than the updated version. What am I doing wrong here? Firefox 3.6.3 - jQuery 1.4.2

• XSLT: moving a grouping html elements into section levels

  - by Jeff

  Hello there, I'm trying to write an XSLT that organizes an HTML file into different section levels depending on the header level. Here is my input: <html> <head> <title></title> </head> <body> <h1>HEADER 1 CONTENT</h1> <p>Level 1 para</p> <p>Level 1 para</p> <p>Level 1 para</p> <p>Level 1 para</p> <h2>Header 2 CONTENT</h2> <p>Level 2 para</p> <p>Level 2 para</p> <p>Level 2 para</p> <p>Level 2 para</p> </body> </html> I'm working with a fairly simple structure at the moment so this pattern will be constant for the time-being. I need an output like this... <document> <section level="1"> <header1>Header 1 CONTENT</header1> <p>Level 1 para</p> <p>Level 1 para</p> <p>Level 1 para</p> <p>Level 1 para</p> <section level="2"> <header2>Header 2 CONTENT</header2> <p>Level 2 para</p> <p>Level 2 para</p> <p>Level 2 para</p> <p>Level 2 para</p> </section> </section> </document> I had been working with this example: Stackoverflow Answer However, I cannot get it to do exactly what I need. I'm using Saxon 9 to run the xslt within Oxygen for dev. I'll be using a cmd/bat file in production. Still Saxon 9. I'd like to handle up to 4 nested section levels if possible. Any help is much appreciated! I need to append onto this as I've encountered another stipulation. I probably should have thought of this before. I'm encountering the following code sample <html> <head> <title></title> </head> <body> <p>Level 1 para</p> <p>Level 1 para</p> <p>Level 1 para</p> <p>Level 1 para</p> <h1>Header 2 CONTENT</h1> <p>Level 2 para</p> <p>Level 2 para</p> <p>Level 2 para</p> <p>Level 2 para</p> </body> </html> As you can see, the <p> is a child of <body> while in my first snippet, <p> was always a child of a header level. My desired result is the same as above except that when I encounter <p> as a child of <body>, it should be wrapped in <section level="1">. <document> <section level="1"> <p>Level 1 para</p> <p>Level 1 para</p> <p>Level 1 para</p> <p>Level 1 para</p> </section> <section level="1"> <header1>Header 2 CONTENT</header1> <p>Level 2 para</p> <p>Level 2 para</p> <p>Level 2 para</p> <p>Level 2 para</p> </section> </document>

• Prevent backspace button from navigating back in Sharepoint 2010 and IE

  - by Machinegon

  as a user requirement I have to disable the backspace button from navigating back in the history. I made the following piece of code //Bind back nutton to prevent escaping the page with backspace $j(document).unbind('keydown').bind('keydown', function (event) { var doPrevent = false; if (event.keyCode === 8) { if(event.target == document.body){ if(event.preventDefault()){ event.preventDefault(); } event.stopEvent(); event.returnValue = false; } } }); This is working perfectly in all the browsers except IE8/7. I cannot bind the input types as exceptions because the content editor in sharepoint allows to modify the text in div or paragraph elements etc. The solution is not working in IE8 because the event.target returns the element that is on mouseover when there's no controls that has the focus. All tips will be appreciated. Thanks!!

• google contacts api service account oauth2.0 sub user

  I am trying to use the Google Contacts API to connect to a user's contact information, on my Google apps domain. Generating an access_token using the gdata api's ContactsService clientlogin function while using the API key for my project works fine, but I would prefer to not store the user's credentials, and from the information I have found that method uses OAuth1.0 So, to use OAuth2.0 I have: Generated a Service Account in the developer's console for my project Granted access to the service account for the scope of https://www.google.com/m8/feeds/ in the Google apps domain admin panel Attempted to generate credentials using SignedJwtAssertionCredentials: credentials = SignedJwtAssertionCredentials( service_account_name=service_account_email, private_key=key_from_p12_file, scope='https://www.google.com/m8/feeds/', sub=user_email') The problem I am running into is that attempting to generate an access token using this method fails. It succeeds in generating the token when I remove the sub parameter, but then that token fails when I try to fetch the user's contacts. Does anyone know why this might be happening?
