Reporting tool for OLAP, *not* OLTP!

- by Stefan Moser

I'm looking for a control that I can put on top of an already existing OLAP star schema to allow the user to define their own "queries" and generate reports. Right now I have some predefined reports built on top of the cubes, but I'd like to allow the user to define their own criteria based on the cubes that I've created. I've found lots of products that will allow you to treat a transactional table like an OLAP cube, but nothing specifically for pre-existing cubes. EDIT: Let me be clear, I know there are countless reporting tools out there that claim to report on OLAP cubes. The problem is they all assume they are looking at transactional data and try to create their own cubes. I have tables that contain tens, if not hundreds of millions of records. Most tools crash when handling this much data, the others just run incredible slowly. I don't want a tool that is targeting the business people. I want a tool that understands what a star and snowflake schema is. I want to be able to tell it what the fact tables are and what the dimension tables are, and then creates a UI on top of them. This is an easier problem to solve for the tool vendor because I am spoon feeding them the cubes. I want to rely on the fact that cubes are a standardized pattern and I want a tool that takes advantage of this fact. I want a tool that targets developers and starts with the assumption that I actually know how to manage my data, it just needs to build pretty reports for me and not crumble under the weight of my data.

need primitive public key signature with out of band key distribution

- by Mike D

I pretty much a complete neophyte at this signature business so I don't know if what I'm asking is nonsense or not. Anyway, here goes... I want to send an out of band message (don't worry about how it gets there) to a program I've written on a distant machine. I want the program to have some confidence the message is legit by attaching a digital signature to the message. The message will be small less than 200 characters. It seems a public key based signature is what I want to use. I could embed the public key in the program. I understand that the program would be vulnerable to attack by anyone who modifies it BUT I'm not too worried about that. The consequences are not dire. I've looked through the MSDN and around the web but the prospect of diving in is daunting. I'm writing in straight c++, no NET framework or other fancy stuff. I've had no experience including NET framework stuff and little luck during previous attempts. Can anyone point me at some very basic resources to get me started? I need to know 1)how to generate the public and private keys 2)how to sign the message 3)how to verify the signature Any help much appreciated. TIA, Mike

Javascript: Error 'Object Required.'

- by javascripthelp

The following is the error popup message I get when I click "Finalize" button on my website: "Line: 298 Char: 5 Error: Object required: 'lobi_c_selected(...)'

Translating CURL to FLEX HTTPRequests

- by Joshua

I am trying to convert from some CURL code to FLEX/ActionScript. Since I am 100% ignorant about CURL and 50% ignorant about Flex and 90% ignorant on HTTP in general... I'm having some significant difficulty. The following CURL code is from http://code.google.com/p/ga-api-http-samples/source/browse/trunk/src/v2/accountFeed.sh I have every reason to believe that it's working correctly. USER_EMAIL="[email protected]" #Insert your Google Account email here USER_PASS="secretpass" #Insert your password here googleAuth="$(curl https://www.google.com/accounts/ClientLogin -s \ -d Email=$USER_EMAIL \ -d Passwd=$USER_PASS \ -d accountType=GOOGLE \ -d source=curl-accountFeed-v2 \ -d service=analytics \ | awk /Auth=.*/)" feedUri="https://www.google.com/analytics/feeds/accounts/default\ ?prettyprint=true" curl $feedUri --silent \ --header "Authorization: GoogleLogin $googleAuth" \ --header "GData-Version: 2" The following is my abortive attempt to translate the above CURL to AS3 var request:URLRequest=new URLRequest("https://www.google.com/analytics/feeds/accounts/default"); request.method=URLRequestMethod.POST; var GoogleAuth:String="$(curl https://www.google.com/accounts/ClientLogin -s " + "-d [email protected] " + "-d Passwd=secretpass " + "-d accountType=GOOGLE " + "-d source=curl-accountFeed-v2" + "-d service=analytics " + "| awk /Auth=.*/)"; request.requestHeaders.push(new URLRequestHeader("Authorization", "GoogleLogin " + GoogleAuth)); request.requestHeaders.push(new URLRequestHeader("GData-Version", "2")); var loader:URLLoader=new URLLoader(); loader.dataFormat=URLLoaderDataFormat.BINARY; loader.addEventListener(Event.COMPLETE, GACompleteHandler); loader.addEventListener(IOErrorEvent.IO_ERROR, GAErrorHandler); loader.addEventListener(SecurityErrorEvent.SECURITY_ERROR, GAErrorHandler); loader.load(request); This probably provides you all with a good laugh, and that's okay, but if you can find any pity on me, please let me know what I'm missing. I readily admit functional ineptitude, therefore letting me know how stupid I am is optional.

Set up Gitosis, but can't clone

- by Tim Rupe

I've set up Gitosis on a remote Ubuntu box which I will refer to as linuxserver as my host in the following commands. I'm also connecting from a Windows box using Cygwin. I followed the instructions according to: http://scie.nti.st/2007/11/14/hosting-git-repositories-the-easy-and-secure-way I had no problems up until I needed to clone the gitosis-admin repository to my local machine git clone git@linuxserver:gitosis-admin.git When I do this, the command executes, but hangs there displaying nothing until I ctrl-c to get back to a command prompt. No messages are displayed at all. I'm pretty sure I have my ssh keys set up properly, because logging in using "ssh linuxserver" into my regular account works perfectly without asking for a password. Edit: Over the weekend I set up a near identical Ubuntu box at home, and had no problem setting up Gitosis. The only difference was that I was connecting from OSX instead of Cygwin. Edit: I've also discovered that when using the Bash Shell provided with "Git Extensions", I have no problems, so the issue definitely seems to be some kind of Cygwin conflict. Edit: Just an update, but about a month after posting this question, I switched to Mercurial, and found that I prefer it much more than git. Thanks for the suggestions, but I don't plan on going back to git to try any of them out.

Speeding up a soap powered website

- by ChrisRamakers

Hi all, We're currently looking into doing some performance tweaking on a website which relies heavily on a Soap webservice. But ... our servers are located in Belgium and the webservice we connect to is locate in San Francisco so it's a long distance connection to say the least. Our website is PHP powered, using PHP's built in SoapClient class. On average a call to the webservice takes 0.7 seconds and we are doing about 3-5 requests per page. All possible request/response caching is already implemented so we are now looking at other ways to improved the connection speed. This is the code which instantiates the SoapClient, what i'm looking for now is other ways/methods to improve speed on single requestes. Anyone has idea's or suggestions? private function _createClient() { try { $wsdl = sprintf($this->config->wsUrl.'?wsdl', $this->wsdl); $client = new SoapClient($wsdl, array( 'soap_version' => SOAP_1_1, 'encoding' => 'utf-8', 'connection_timeout' => 5, 'cache_wsdl' => 1, 'trace' => 1, 'features' => SOAP_SINGLE_ELEMENT_ARRAYS )); $header_tags = array('username' => new SOAPVar($this->config->wsUsername, XSD_STRING, null, null, null, $this->ns), 'password' => new SOAPVar(md5($this->config->wsPassword), XSD_STRING, null, null, null, $this->ns)); $header_body = new SOAPVar($header_tags, SOAP_ENC_OBJECT); $header = new SOAPHeader($this->ns, 'AuthHeaderElement', $header_body); $client->__setSoapHeaders($header); } catch (SoapFault $e){ controller('Error')->error($id.': Webservice connection error '.$e->getCode()); exit; } $this->client = $client; return $this->client; }

share the same cookie between two website using PHP cURL extension

- by powerboy

I want to get the contents of some emails in my gmail account. I would like to use the PHP cURL extension to do this. I followed these steps in my first try: In the PHP code, output the contents of https://www.google.com/accounts/ServiceLoginAuth. In the browser, the user input username and password to login. In the PHP code, save cookies in a file named cookie.txt. In the PHP code, send request to https://mail.google.com/ along with cookies retrieved from cookie.txt and output the contents. The following code does not work: $login_url = 'https://www.google.com/accounts/ServiceLoginAuth'; $gmail_url = 'https://mail.google.com/'; $cookie_file = dirname(__FILE__) . '/cookie.txt'; $ch = curl_init(); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($ch, CURLOPT_HEADER, false); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file); curl_setopt($ch, CURLOPT_URL, $login_url); $output = curl_exec($ch); echo $output; curl_setopt($ch, CURLOPT_URL, $gmail_url); curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file); $output = curl_exec($ch); echo $output; curl_close($ch);

Saving "heavy" figure to PDF in MATLAB - rendering problem

- by yuk

I generate a figure in MATLAB with lot amount of points (100000+) and want to save it into a PDF file. With zbuffer or painters renderer I've got very large and slowly opened file (over 4 Mb) - all points are in vector format. Using OpenGL renderer rasterize the figure in PDF, ok for the plot, but not good for text labels. The file size is about 150 Kb. Try this simplified code, for example: x=linspace(1,10,100000); y=sin(x)+randn(size(x)); plot(x,y,'.') set(gcf,'Renderer','zbuffer') print -dpdf -r300 testpdf_zb set(gcf,'Renderer','painters') print -dpdf -r300 testpdf_pa set(gcf,'Renderer','opengl') print -dpdf -r300 testpdf_op The actual figure is much more complex with several axes and different types of plots. Is there a way to rasterize the figure, but keep text labels as vectors? Another problem with OpenGL is that is does not work in terminal mode (-nosplash -nodesktop) under Mac OSX. Looks like OpenGL is not supported. I have to use terminal mode for automation. The MATLAB version I run is 2007b. Mac OSX server 10.4.

WHy am I unable to add text along with <%# Container.DataItem %> in repeater in user control

- by Jamie Hartnoll

I have a User Control which is dynamically placed by CodeBehind as follows: Dim myControl As Control = CType(Page.LoadControl("~/Controls/mainMenu.ascx"), Control) If InStr(Request.ServerVariables("url"), "/Login.aspx") <= 0 Then mainMenu.Controls.Add(myControl) End If As per an example from my previous question on here. Within this Control is a repeater which calls a database to generate values. My Repeater mark-up is as follows <asp:Repeater runat="server" ID="locationRepeater" OnItemDataBound="getQuestionCount"> <ItemTemplate> <p id='locationQuestions' title='<%# Container.DataItem %>' runat='server'></p> </ItemTemplate> </asp:Repeater> The example above works fine, but I want to be able to prepend text to <%# Container.DataItem %> in the title attribute of that <p to print to the browser like this is some text DATA_ITEM_OUTPUT When I try to do that though, it prints this is some text <%# Container.DataItem %> exactly like that, ie, turning <%# Container.DataItem %> into text, NOT the value from the repeater code. It was working fine before I made it into a dynamically inserted control, so I am thinking I might have something being generated in the wrong order, but given that it works without any prepended text, I am stumped to fix it! I'm new to .net and using vb.net, please could someone point me in the right direction?

how to create an function using jquery live? [Solved]

Hey all i am trying to create a function that well keep the user in lightbox images while he adds to cart, for a demo you can visit secure.sabayafrah.com username: mahmud password: mahmud when you click at any image it well enlarge using lightbox v2, so when the user clicks at the image add, it well refresh the page, when i asked about it at jcart support form they informed me to use jquery live, but i dont know how to do it but as far as i tried this code which i used but still nothing is happening jQuery(function($) { $('#button') .livequery(eventType, function(event) { alert('clicked'); // to check if it works or not return false; }); }); i also used jQuery(function($) { $('input=[name=addto') .livequery(eventType, function(event) { alert('clicked'); // to check if it works or not return false; }); }); yet nothing worked for code to create those images http://pasite.org/code/572 Update 1: i have done this function adding(form){ $( "form.jcart" ).livequery('submit', function() {var b=$(this).find('input[name=<?php echo $jcart['item_id']?>]').val();var c=$(this).find('input[name=<?php echo $jcart['item_price']?>]').val();var d=$(this).find('input[name=<?php echo $jcart['item_name']?>]').val();var e=$(this).find('input[name=<?php echo $jcart['item_qty']?>]').val();var f=$(this).find('input[name=<?php echo $jcart['item_add']?>]').val();$.post('<?php echo $jcart['path'];?>jcart-relay.php',{"<?php echo $jcart['item_id']?>":b,"<?php echo $jcart['item_price']?>":c,"<?php echo $jcart['item_name']?>":d,"<?php echo $jcart['item_qty']?>":e,"<?php echo $jcart['item_add']?>":f} }); return false; } and it seems to add to jcart but yet it still refreshes

How do I process multipart http responses in Ruby Net:HTTP?

SQL Server Index cost

- by yellowstar

I have read that one of the tradeoffs for adding table indexes in SQL Server is the increased cost of insert/update/delete queries to benefit the performance of select queries. I can conceptually understand what happens in the case of an insert because SQL Server has to write entries into each index matching the new rows, but update and delete are a little more murky to me because I can't quite wrap my head around what the database engine has to do. Let's take DELETE as an example and assume I have the following schema (pardon the pseudo-SQL) TABLE Foo col1 int ,col2 int ,col3 int ,col4 int PRIMARY KEY (col1,col2) INDEX IX_1 col3 INCLUDE col4 Now, if I issue the statement DELETE FROM Foo WHERE col1=12 AND col2 > 34 I understand what the engine must do to update the table (or clustered index if you prefer). The index is set up to make it easy to find the range of rows to be removed and do so. However, at this point it also needs to update IX_1 and the query that I gave it gives no obvious efficient way for the database engine to find the rows to update. Is it forced to do a full index scan at this point? Does the engine read the rows from the clustered index first and generate a smarter internal delete against the index? It might help me to wrap my head around this if I understood better what is going on under the hood, but I guess my real question is this. I have a database that is spending a significant amount of time in delete and I'm trying to figure out what I can do about it. When I display the execution plan for the deletion, it just shows an entry for "Clustered Index Delete" on table Foo which lists in the details section the other indices that need to be updated but I don't get any indication of the relative cost of these other indices. Are they all equal in this case? Is there some way that I can estimate the impact of removing one or more of these indices without having to actually try it?

GUI for generating XML

- by Kenston

Hello. Does anybody know of GUIs for generating XMLs? This means the user will not be presented with an IDE with support for XML for him to type XML codes. This would be helpful for non-technical people using the system. I know this sounds easy, given many libraries that can help in generating XMLs. The issue here is that the schema is really that flexible rather than being straightforward like representing books in a library with their properties. Imagine HTML, where we can create font tags inside a body, a table, a div, or nested even within itself. The solution is a WYSIWYG application that allows user to generate html codes (XML). However, that is good for XML applied in webpages since they involve visual aspect and design. My application of XML would focus on representing some conceptual and computational definitions, much like sql-like syntax, but more than that. I'm actually after the approach or previous works done or tried, although having a library/working framework for that would be better. Btw, I'm using Java for this project. Currently, I'm just thinking of presenting element tags where user will be able to drag and drop them and nest them with each other. And perhaps, assist them through a forms in inputing values for XML attributes. I'm still hoping if there are better ideas from the community. Thank you.

CSS doesn't apply to dynamically created elements in IE 7?

- by Austin Hyde

In the project I am working on, I dynamically generate (with javascript) filters that look like this: <div class="filter"> <a ... class="filter_delete_link">Delete</a> <div class="filter_field"> ... </div> <div class="filter_compare"> ... </div> <div class="filter_constraint"> ... </div> <div class="filter_logic"> ... </div> </div> And I have CSS that applies to each filter (for example): .filter a.filter_delete_link{ display:block; height:16px; background: url('../images/remove_16.gif') no-repeat; padding-left:20px; } However, it seems in IE 7 (and probably 6 for that matter), these styles don't get applied to the new filters. Everything works perfectly in Firefox/Chrome/IE8. Using the IE8 developer tools, set to IE7 mode, the browser can see the new elements, and can see the CSS, but just isn't applying the CSS. Is there a way to force IE to reload styles, or perhaps is there a better way to fix this?

Storing User Information in Session with aspNetMembershipProvider

- by Muhammad Adeel Zahid

Hi Everyone, i m developing an application in .NET mvc2. i m using aspnetMembershipProvider for User registration and related activities. i need some custom information about user that i stored in a separate table (sysUser for example) and linked it to aspnetUser table through foreign key. after Login i need to fetch user's credentials from sysUser table and push it to the session. For this Account controller's Logon method seemed best to me and i pasted following code in my Logon ActionResult if (!ValidateLogOn(userName, password)) { return View(); } FormsAuth.SignIn(userName, rememberMe); ApplicationRepository _ApplicationRepository = new ApplicationRepository(); MembershipUser aspUser = Membership.GetUser(userName); SessionUser CurrentUser = _ApplicationRepository.GetUserCredentials(aspUser.ProviderUserKey.ToString()); //Session["CurrentUser"] = CurrentUser; if (!String.IsNullOrEmpty(returnUrl)) { return Redirect(returnUrl); } else { return RedirectToAction("Index", "Home"); } The code is working perfectly for me and put my desired information in the session but the thing is that if a user selects Remember me and on his next visit he won't have to Log in and i would not find my desired information in the Session. Can anyone guide me where should i put my code that stores the user information in the session. any Help is Highly appreciated Regards Adeel

stopping backspace on multiple browsers using jQuery

- by jboyd

I am attempting to stop a backspace keydown event from being handled by browsers, I'm using the jquery library, so I need to get the original event, but on some browsers (firefox at least) I get an error when trying to set the original events keyCode = 0, it gives and error saying that only a getter exists for that property. function blockBackspace(event) { var altKey = event.originalEvent.altKey; var srcElementType = event.originalEvent.srcElement; if( (altKey) || ((event.keyCode == 8) && (srcElementType != "text" && srcElementType != "textarea" && srcElementType != "password")) || ((event.ctrlKey) && ((event.keyCode == 78) || (event.keyCode == 82)) ) || (event.keyCode == 116) ) { event.keyCode = 0; event.returnValue = false; event.originalEvent.keyCode = 0; event.originalEvent.returnValue = false; //sets process backspaceFlag to keep multiple handlers from removing text processBackspace = true; } } so I'm not exactly sure what to do next, every solution I find yields more problems. There must be ways around this problem or else other text areas (that's kind of what I'm building) would not work

Best way to store list of numbers and to retrieve them

- by bingoNumbers

Hi. What is the best way to store a list of random numbers (like lotto/bingo numbers) and retrieve them? I'd like to store on a Database a number of rows, where each row contains 5-10 numbers ranging from 0 to 90. I will store a big number of those rows. What I'd like to be able is to retrieve the rows that have at least X number in common to a newly generated row. Example: [3,4,33,67,85,99] [55,56,77,89,98,99] [3,4,23,47,85,91] Those are on the DB I will generate this: [1,2,11,45,47,88] and now I want to get the rows that have at least 1 number in common with this one. The easiest (and dumbest?) way is to make 6 select and check for similar results. I thought to store numbers with a large binary string like 000000000000000000000100000000010010110000000000000000000000000 with 99 numbers where each number represent a number from 1 to 99, so if I have 1 at the 44th position, it means that I have 44 on that row. This method is probably shifting the difficult tasks to the Db but it's again not very smart. Any suggestion?

How to hide zero values in bar3 plot in MATLAB

- by Doresoom

I've got a 2-D histogram (the plot is 3D - several histograms graphed side by side) that I've generated with the bar3 plot command. However, all the zero values show up as flat squares in the x-y plane. Is there a way I can prevent MATLAB from displaying the values? I already tried replacing all zeros with NaNs, but it didn't change anything about the plot. Here's the code I've been experimenting with: x1=normrnd(50,15,100,1); %generate random data to test code x2=normrnd(40,13,100,1); x3=normrnd(65,12,100,1); low=min([x1;x2;x3]); high=max([x1;x2;x3]); y=linspace(low,high,(high-low)/4); %establish consistent bins for histogram z1=hist(x1,y); z2=hist(x2,y); z3=hist(x3,y); z=[z1;z2;z3]'; bar3(z) As you can see, there are quite a few zero values on the plot. Closing the figure and re-plotting after replacing zeros with NaNs seems to change nothing: close z(z==0)=NaN; bar3(z)

SubSonic 3 screws up selecteditem?

- by SteveCav

If you have a moment, please try this: -Download Subsonic 3. -Start a new proj and add SS's ActiveRecord templates. -Point it to any SQL Server DB and generate the classes. -Add a WPF project. -Create a window and add a combobox or listbox. -Set the ItemsSource from the SS DAL, and format it how you wish. -Add a button that will show you some value from the SelectedItem (using messagebox, console, whatever). -Run the project. -Click on the third item in the list. -Click on the second item in the list. -Click on the button. When I do that, the button gives me the value of the THIRD item, not the second. In other words, once the SelectedItem is set the first time it STAYS, no matter which item is subsequently highlighted on the screen. This is happening to me whatever control I use (combobox, listbox, even datagrid) and it ONLY happens with Subsonic Activerecord objects. If I write my own POCOs with identical properties and bind a list of them instead, the controls behave as expected. Does this happen to you? Any ideas?

What's a good Java API for creating Word documents?

- by Bill James

I have a new app I'll be working on where I have to generate a Word document that contains tables, graphs, a table of contents and text. What's a good API to use for this? How sure are you that it supports graphs, ToCs, and tables? What are some hidden gotcha's in using them? Some clarifications: I can't output a PDF, they want a Word doc. They're using MS Word 2003 (or 2007), not OpenOffice Application is running on *nix app-server It'd be nice if I could start with a template doc and just fill in some spaces with tables, graphs, etc. Thanks for the help. Edit: Several good answers below, each with their own faults as far as my current situation. Hard to pick a "final answer" from them. Think I'll leave it open, and hope for better solutions to be created. Edit: The OpenOffice UNO project does seem to be closest to what I asked for. While POI is certainly more mainstream, it's too immature for what I want.

In IIS6, how to provide authenticated access to static files on remote server

- by frankadelic

We have a library of ZIP files that we would like to make available for download at an ASP.NET site. The files are sitting on a NAS device that is accessible from out web farm. Here is our initial strategy: Map an IIS virtual directory to the shared drive at path /zipfiles Users can download the zip files when given the URL However, if users share links to the files, anyone can download them. We would instead like to make use of the ASP.NET forms authentication in our site to validate users' requests before initiating the file transfer. A few problems: A request for a zip file is handled by IIS, not ASP.NET. So it is not subject to forms authentication. In addition, we don't want ASP.NET to handle the request, because it uses up an ASP.NET thread and is not scalable for download of large files. So, configuring the asp.net dll to handle *.zip requests is not an option. Any ideas on this? One idea we've tossed around is this: Initial request for download will be for an ashx handler. This handler will, after authentication, generate a download token which is saved to a database. Then, the user is redirected to the file with token appended in QueryString (e.g. /files/xyz.zip?token=123456789). An ISAPI plugin will be used to check the token. Also, the token will expire after x amount of time. Any thoughts on this? I have not implemented an ISAPI plugin so I'm not sure if this will even work. I would like to avoid custom coding since security is an issue and I'd prefer to use a time-tested solution.

Entity Framework and stored procedure returning temp table Issues

- by kaplooeymom

(Disclaimer - I'm not the database designer. I'm just the poor developer what has to make this work.) There are 17 (at the moment) tables with identical structure - name, address, phone number. Given a phone number, I have to check to see if there's a matching entry in any of the tables, then return that address. So, I created a view to get the list of tables (there's a ref table that holds that info), then I created a stored procedure to create a temp table, using cursors, check each table in the view for the phone number, using sql concatenation. If a record is found, insert it into the temp table. return the rows from the temp table. This all works in straight T-SQL. Now, I'm trying to use Entity Framework 4+ to call the stored procedure. But the function import interface won't generate columns. It says return type = none, and the LINQ code expects an int and won't compile. Any ideas on how to make this work? I know I can move the check tables part to code, if I absolutely have to, but I'd rather have the above method work.

What java web application framework to use?

- by frohiky

One of the main products of my company is an Oracle Forms (and Reports) based application, that "needs" to be re-written in another technology. Why? Users want a more rich interface experience, and we want, preferably, to reduce costs with an open source application server. For this (HUGE) project, we intend to use a java web application framework, keep these points in mind: We have: hundreds of tables on our database (the ORM must be as flexible as possible); some logic which is (and will still be) based on PL/SQL procedures/functions/packages; a lot of CRUDs (the application itself is of an considerable size); a demand to work with/generate documents and workflows; an intranet based user environment; We want: to offer a RIA interface experience; use (if possible) an open source app server; a rapid (as possible) development framework; a somewhat mature framework with a "wise" roadmap (and a considerable community support); a MVC approach combined with JS or GWT widgets (e.g. Vaadin or SmartGWT); Well, in the past weeks I've read a lot of posts, Q&As on stackoverflow, and much more: Wicket, JSF, Tapestry, Grails, GWT, Struts2, Play, Spring, Seam, Echo, .... the list goes on! I've even researched about Alfresco..! The obvious question: Which one to use? At this time, any insight, recommendation, shared experience, advice will be more then welcome!
