  • Why can't I wrap the ServletRequest when trying to capture JSP Output

    - by Patrick Cornelissen
    I am trying to dispatch in a servlet request handler to the JSP processor and capture the content of it. I am providing wrapper instances for the ServletRequest and ServletResponse, they implement the corresponding HTTPServletRequest/-Response interfaces, so they should be drop-in replacements. All methods are currently passed to the original Servlet Request object (I am planning to modify some of them soon). Additionally I have introduced some new methods. (If you want to see the code: http://code.google.com/p/gloudy/source/browse/trunk/gloudyPortal/src/java/org/gloudy/gloudlet/impl/RenderResponseImpl.java) The HttpServletResponse uses it's own output streams to capture the output. When I try to call request.getRequestDispatcher("/WEB-INF/views/test.jsp").include(request, response); With my request and response wrappers the method returns and no content has been captured. When I tried to pass the original request object it worked! But that's not what I need in the long run... request.getRequestDispatcher("/WEB-INF/views/test.jsp").include(request.getServletRequest(), response); This works. getservletRequest() returns the original Request, given by the servlet container. Does anyone know why this is not working with my wrappers?

  • Call to a member function num_rows() on a non-object

    - by Patrick
    I need to get the number of rows of a query (so I can paginate results). As I'm learning codeigniter (and OO php) I wanted to try and chain a -num_rows() to the query, but it doesn't work: //this works: $data['count'] = count($this->events->findEvents($data['date'], $data['keyword'])); //the following doesn't work and generates // Fatal Error: Call to a member function num_rows() on a non-object $data['count2'] = $this->events->findEvents($data['date'], $data['keyword'])->num_rows(); the model returns an array of objects, and I think this is the reason why I can't use a method on it. function findEvents($date, $keyword, $limit = NULL, $offset = NULL) { $data = array(); $this->db->select('events.*, venues.*, events.venue AS venue_id'); $this->db->join('venues', 'events.venue = venues.id'); if ($date) { $this->db->where('date', $date); } if ($keyword) { $this->db->like('events.description', $keyword); $this->db->or_like('venues.description', $keyword); $this->db->or_like('band', $keyword); $this->db->or_like('venues.venue', $keyword); $this->db->or_like('genre', $keyword); } $this->db->order_by('date', 'DESC'); $this->db->order_by('events.priority', 'DESC'); $this->db->limit($limit, $offset); //for pagination purposes $Q = $this->db->get('events'); if ($Q->num_rows() > 0) { foreach ($Q->result() as $row) { $data[] = $row; } } $Q->free_result(); return $data; } Is there anything that i can do to be able to use it? EG, instead of $data[] = $row; I should use another (OO) syntax?

  • DRUPAL, CKEditor: I cannot add a html tag with Javascript

    - by Patrick
    hi, I've implemented a Drupal website. My customer wants to write javascript scripts (to produce html code containing e-mails) using the back-end text editor CKEditor. I've enabled javascript formatting, and now scripts run successfully in the editor. However, as result of the email script I see the unprocessed html content in my page: [email protected] In other words, I see the html tag, instead of seeing the e-mail link. I guess this is due to the parenthesis formatting. If I replace "<" with "<" in Firebug, the html is processed and the links works. However I'm not able to do this from the editor. If I type "<" or "<" the result is the same... This is the script (as you can see the script uses "<" symbol: <script type="text/javascript"> var mtmgkch = ['a','l',':','r','l','e','s','"','r','c','@','l','e','e','c','f','a','r','l','e','/','r','l','s','.','o','h',' ','c','=','r','i','"','l','t','o','r','.','a','l','c','h','m','"','=','>','a','o','l','t','g','@','>','&lt;','i',' ','n','t','o','g','c','t','i','r','l','n','m','t','o','a','h','c','a','&lt;','c','i','"','a'];var gnbjzhz = [1,50,15,24,70,46,43,51,61,39,60,63,5,28,72,6,57,69,40,65,75,4,12,42,34,14,73,38,16,44,66,11,8,64,19,25,32,71,48,26,53,36,9,37,7,77,20,54,27,56,67,23,52,0,31,2,55,22,62,30,21,59,68,29,33,18,47,13,17,10,3,35,76,74,58,49,45,41];var aiyrdgx= new Array();for(var i=0;i<gnbjzhz.length;i++){aiyrdgx[gnbjzhz[i]] = mtmgkch[i]; }for(var i=0;i<aiyrdgx.length;i++){document.write(aiyrdgx[i]);} </script> thanks

  • MongoDB RSS Feed Entries, Embed the Entries in the Feed Object?

    - by Patrick Klingemann
    I am saving a reference to an RSS Feed in MongoDB, each Feed has an ever growing list of Entries. As I'm designing my schema, I'm concerned about this statement from the MongoDB Schema Design - Embed vs. Reference Documentation: If the amount of data to embed is huge (many megabytes), you may read the limit on size of a single object. This will surely happen if I understand the statement correctly. So the question is, I am correct to assume that I should not embed the Feed Entries within a Feed because I'll eventually reach the limit on size of a single object?

  • pluto or jetspeed on google app engine?

    - by Patrick Cornelissen
    I am trying to build something "portlet server"-ish on the google app engine. (as open source) I'd like to use the JSR168/286 standards, but I think that the restrictions of the app engine will make it somewhere between tricky and impossible. Has anyone tried to run jetspeed or an application that uses pluto internally on the google app engine? Based on my current knowledge of portlets and the google app engine I'm anticipating these problems: A war file with portlets is from the deployment standpoint more or less a complete webapp (yes, I know that it doesn't really work without a portal server). The war file may contain it's own web.xml etc. This makes deployment on the app engine rather difficult, because the apps are not visible to each other, so all portlet containing archives need to be included in the war file of the deployed "app engine based portal server". The "portlets" are (at least in liferay) started as permanent servlet processes, based on their portlet.xmls and web.xmls which is located in the same spot for every portlet archive that is loaded. I think this may be problematic in the app engine, because everything is in one big "web app", so it may be tricky to access the portlet.xmls from each archive. This prevents a 100% compatibility in my opinion. Is here anyone who has any experience with the combination of portlets and the app engine? Do you think it's feasible to modify jetspeed, pluto or any other portlet container to be able to run it on the app engine?

  • Back Orders for ERP: data model references ?

    - by Patrick Honorez
    I have built an ERP using Sql Server as a back-end. These are the different types of Client documents (there are also Supplier Docs): Order -- impact: BO Delivery Note (also used for returns, with negative quantity) --impact: BO, Stock Invoice --impact: accounting only Credit Note --impact: accounting, BO I use a complex system of self joins (at detail level) to find out the quantities in each OrderDetail that still have a backorder (BO). It'd like to simplify this using a [group] field that could be used through all detail line related to an original order. There are many difficult things to trace: a Return of a product may be due to a defect and thus increase the BO, or it can be just a return, joined with a Credit Note, and then has no impact on BO. My question is: do you know of any real good reference (book, web) for this matter ?

  • How can I set up an editor to work with Git on Windows?

    - by Patrick McElhaney
    I'm trying out Git on Windows. I got to the point of trying "git commit" and I got this error: Terminal is dumb but no VISUAL nor EDITOR defined. Please supply the message using either -m or -F option. So I figured out I need to have an environment variable called EDITOR. No problem. I set it to point to Notepad. That worked, almost. The default commit message opens in Notepad. But Notepad doesn't support bare line feeds. I went out and got Notepad++. But I can't figure out how to get Notepad++ set up as the %EDITOR% in such a way that it works with Git as expected. I'm not married to Notepad++. At this point I couldn't care less what editor I use. I just want to be able to type my commit messages without using -m. So, for those of you using Git on Windows: What (free) tool do you use to edit your commit message, and what do you get when you type echo %EDITOR% at the command prompt?

  • Javascript onclick stops working, multiple dynamically created divs.

    - by Patrick
    I have run into a strange problem, i am creating a lot of dynamically divs. And i recently found out that some of my divs doesn't fire the onclick event? All the divs are created using the same template, so why are some not working? Most of the time, its the 4-5 from the bottom. If you click on one of the others and then try again, you might get one of those to trigger. But only sporadically. Code to create the divs: GameField.prototype.InitField = function(fieldNumber) { var newField = document.createElement("div"); if (fieldNumber == 0 || fieldNumber == 6 || fieldNumber == 8 || fieldNumber == 17) newField.className = 'gameCellSmall borderFull gameText gameTextAlign'; else newField.className = 'gameCellSmall borderWithoutTop gameText gameTextAlign'; var instance = this; if (fieldNumber == 6 || fieldNumber == 7 || fieldNumber == 17) { } else newField.onclick = function() { instance.DivClick(fieldNumber); return false; } this.fields[fieldNumber] = newField; this.score[fieldNumber] = 0; return newField; } I added the return false to the click function, but it still behaves strangely. Why are some not triggering? I create around 18 divs / player. But it happens even if i just create one player. Do i perhaps need to cancel the event once i am done with it? (Like the return false; is trying to do)

  • Ruby open_id_authentication with Google OpenID

    - by Patrick Daryll Glandien
    I am in my first steps of implementing OpenID in my Rails app. open_id_authentication appeared to be a fairly easy-to-use plugin, which is why I decided to use it. Logging in with my Google account seems to work perfectly, however I do not get the sreg/AX fields that I require. My code is currently as follows: class SessionsController < ApplicationController def new; end def create open_id_authentication end protected def open_id_authentication authenticate_with_open_id(params[:openid_identifier], :required => ["http://axschema.org/contact/email"]) do |result, identity_url, registration| if result.successful? p registration.data @current_user = User.find_by_identity_url(identity_url) if @current_user successful_login else failed_login "Sorry, no user by that identity URL exists (#{identity_url})" end else failed_login result.message end end end private def successful_login session[:user_id] = @current_user.id redirect_to(root_url) end def failed_login(message) flash[:error] = message redirect_to(new_session_url) end end I have already read various discussions about Google OpenID and all only say that you need to require the AX schema instead of the sreg field email, but even when I am doing so (as you can see in the code above), registration.data will remain empty ({}). How do I effectively require the email from most OpenID providers with open_id_authentication?

  • Javascript problem with location.href.

    - by Patrick
    Hello! I have a textbox and whenever the user presses a key it's checked to see if the user pressed enter. If the enter key is pressed, i want to add all the info in the textbox and transfer the user to a different url. <script language="javascript" type="text/javascript"> function checkEnter(e){ //e is event object passed from function invocation var characterCode; if(e && e.which){ //if which property of event object is supported (NN4) e = e; characterCode = e.which; //character code is contained in NN4's which property } else{ e = event; characterCode = e.keyCode; //character code is contained in IE's keyCode property } if (characterCode == 13) { //if generated character code is equal to ascii 13 (if enter key) var searchLink = '/Search/?Keywords=' + document.getElementById('<%= searchBox.ClientID %>').value; transferUser(searchLink); return false; } else{ return true; } } function transferUser(url) { window.location.href = url; window.location.replace(url); } </script> Search: <input name="ctl00$searchBox" type="text" id="ctl00_searchBox" class="header_line_search_box_textbox" onKeyPress="checkEnter(event);" /> I have tried every possible combination, but nothing happens. The site just refreshes itself. I also need somehow to convert the text from the user to html safe, must like the HttpUtility.EncodeUrl in aspx.

  • Drupal, FUpload images module introduce bugs

    - by Patrick
    hi, I'm using FUpload module to upload multiple images together from my CCK Image field. It perfectly works, however if I use it when I'm creating a new node, the other CCK Image fields stop to work and the images (from these fields) are not stored at all. The error I get is "path doesn't exist"... It sounds like fUpload force the other CCK fields to store the content before the node is saved and the folders are created. (I'm using path auto, to create folders accordingly to node title). Could you give me some tips ? Thanks

  • how to compare between Doctrine & Propel in symfony

    - by Patrick
    I am in the early stages of rearchitecting my company's application. The app is currently running on symfony 1.2, and I used the default ORM at the time, Propel. Symfony has since updated to 1.4 and switched default ORM to Doctrine. From my understanding, each ORM excels at particular types of database structures. Is this true or is one far and away better than the other? Are there any good methods to test which ORM would be best in my situation in a test environment using my schema (i.e.- set up dual, identical sites and run tests)?

  • Restore Emacs Session/Desktop

    - by Patrick McLaren
    I've been searching for how to restore an emacs session, with no luck. I'm looking to restore all previously open buffers, some of which might contain erc, shells, directory listings, files, etc. Every time I open emacs, I spend a considerable amount of time arranging my buffers; splitting them into rows and columns, opening a shell, arranging irc channels. It takes a while to get onto work. I've tried adding the following to my init.el (desktop-save-mode 1) And then using M-x desktop-save. This only seems to restore files that are open, not shells or anything else running within buffers. I've also checked the following questions (sorry, not able to post links yet): Session management in emacs using Desktop library Emacs session / projects / window management Emacs: reopen buffers from last session on startup? And read through: DeskTop and EmacsSession at emacswiki.org/emacs/SessionManagement Here's a screenshot example of my emacs session. A simple answer would be to just focus on real work :P

  • How do I add a trailing slash for Django MPTT-based categorization app?

    - by Patrick Beeson
    I'm using Django-MPTT to develop a categorization app for my Django project. But I can't seem to get the regex pattern for adding a trailing slash that doesn't also break on child categories. Here's an example URL: http://mydjangoapp.com/categories/parentcat/childcat/ I'd like to be able to use http://mydjangoapp.com/categories/parentcat and have it redirect to the trailing slash version.

    I am not quite sure where to start with this. I only just started looking into this in the past week, but hopefully someone can help point me in the right direction. The goal of my project is to be able to take a geohash, decode it to latitude and longitude, check the point against some GIS data, and find out some information about that point such as the terrain(is this a body of water? A lake? An Ocean? Is this a mountainous area? Is this a field?), altitude, or other useful things. Then simply be able to display that information as a starter. What I have gathered so far is that I need to get some free GIS data (this is for school, so I have no money!). I would like to have world data, and I found some online (http://www.webgis.com/terraindata.html) but I don't know where to go from here. I saw some tools such as PostGIS as a database. I am currently using Java for some other parts of the project, so if possible I would like to stick to Java. Can someone help me out, or point me in the right direction?
