• Error using SoapClient() in PHP [migrated]

  - by Dhaval

  I'm trying to access WSDL(Web Service Definition Language) file using SoapClient() of PHP. I found that WSDL file is authenticated. I tried with passing credentials on an array by another parameter and active SSL on my server, still I'm getting an error. Here is the code I'm using: $client = new SoapClient("https://webservices.chargepointportal.net:8081/coulomb_api_1.1.wsdl",array("trace" = "1","Username" = "username","Password" = "password")); Here is the error I'm getting: Warning: SoapClient::SoapClient(https://webservices.chargepointportal.net:8081/coulomb_api_1.1.wsdl) [soapclient.soapclient]: failed to open stream: Connection timed out in PATH_TO_FILE on line 80 Warning: SoapClient::SoapClient() [soapclient.soapclient]: I/O warning : failed to load external entity "https://webservices.chargepointportal.net:8081/coulomb_api_1.1.wsdl" in PATH_TO_FILE on line 80 Fatal error: Uncaught SoapFault exception: [WSDL] SOAP-ERROR: Parsing WSDL: Couldn't load from 'https://webservices.chargepointportal.net:8081/coulomb_api_1.1.wsdl' : failed to load external entity "https://webservices.chargepointportal.net:8081/coulomb_api_1.1.wsdl" in PATH_TO_FILE:80 Stack trace: #0 /home2/wingstec/public_html/widget/API/index.php(80): SoapClient-SoapClient('https://webserv...', Array) #1 {main} thrown in PATH_TO_FILE on line 80 It seems that error says file not exist at the path we given but when we run that path directly on browser then we're getting that file Can anyone help me to figure out what the exactly problem is?

• Strategy for restoring state via URL in web apps

  - by JW01

  This is a question about modern web apps, where a single page is loaded, and all subsequent navigation is done by XHR calls and modifying the DOM. We can use libraries that manipulate the hash string, which let us navigate by URL and support the back/forward buttons. But to use those libraries, we need to be able to move the UI from any one state to any other. Is there a good strategy for moving between UI states, that also allows them to be restored from scratch when you load a new URL? In a complex app, you might have a lot of different states. You don't want to reload the entire UI each time you change states. But you also don't want to require separate methods for moving from every state to each every state. Typically we need to: Restore a state from scratch, when you enter a new URL or hit Reload. Move from one state to another, when you use the Back/Forward buttons. Move from one state to another, when you perform an action within your app (like clicking a link). Move to certain states that shouldn't be added to the history, like ones that appear after form submissions. Move to some states that are built on the previous state, like a drill-down list. When you perform actions within your app, there's the additional question of which comes first: Do you change the URL, listen for the URL change, and change your state in response to it? Or do you change your state, then change the URL, but don't do anything in response? Does anyone have some experience to share on this topic?

• RMS java web framework

  - by Kamil Tomšík

  We're currently reconsidering technologies and frameworks to get more agile with "simple" RMS CRUD-based projects. In short, short-living things like this Right now we have custom extension on top of SmartGWT but after some time it has proven not to be enough flexible. I also personally dislike that java-js compilation process and the whole GWT codebase. Not only its ugly designed, it also makes certain low-level js things very complicated if not completely impossible. So what I'm looking for is: closest to web as possible, like JSF or possibly Tapestry, it is very important to be able get "low" and weave framework if necessary. Happens more often than we thought. datagrid capable - Ext.js & PrimeFaces looks pretty good, Vaadin does too. db-schema generators (optional, no matter in which way) If it were only on me, I'd probably stick to Ext.js + custom rest-based java solution, possibly generated from database schema (not sure about concrete tooling yet) I only does have experience with vanilla Ext.js, vanilla GWT and JSF 2.0 / Seam, so it kinda hard for me to judge or even propose other frameworks. What would be your proposition? What are the problems you've faced, what was your solution and how hard do you think it was to deal with them in "big picture"?

• Web to Print system - which client side technology should I use

  - by mr null

  I'm getting started to develop Web to Print system. My main concern is which client-side techology should I use: jQuery/CSS Flex/ActionScript or something else? For now, idea is that user/customer choose Product eg: Business card Attributes: Dimensions,Paper type, ... etc Template or blank Adjust product (editor) Preview & order Output should be PDF 300dpi. My main issue is: adding/adjusting text in editor. (font size, font family...). Because application should be cross browser. And I think that 10px Arial can't be the same in Firefox 5 and IE 8. It must be pixel perfect in every browser. If somebody order $100 of business cards, and text is different that he/she saw when ordering - that is a big problem. So, Flash platform should be the answer. But, as I see it's dying technology, 2012 is here - HTML5 is replacing Flash rapidly. I hope that you understand me, so every guideline or few smart words would be very appreciating.

• what is the Web development process efficiency judgment criteria

  - by Ahmed safan

  I'm working as a web developer and I want to be able to determine if I'm efficient. Does this include the how long it take to accomplish tasks such as: Server side code for the site logic with one language or multiple php,asp,asp.net. Client side code like javascript with jquery for ajax, menus and other interactivity Page layout, html, css (color, fonts (but I have no artistic sense!)) The needs of the site and how it will work (planning) How can i judge how long it will take to complete a website? The site has CMS for adding and editing news, products, articles on the experience of the company. Also, they can edit team work, add Recreational Activities and a logo gallery with compressed psd download, and send messages to cpanel and to email. You are starting from scratch except JQuery and PHPmailer. How can I estimate how long the job will take, and how can I calculate the required time to finish any new projects? I'm so sorry for many scattered questions, but I'm in my first experiment and I want to take benefits from the great experience of those who have it.

• Standards & compliances for secure web application development?

  - by MarkusK

  I am working with developers right now that write code the way they want and when i tell them to do it other way they respond that its just matter of preference how to do it and they have their way and i have mine. I am not talking about the formatting of code, but rather of way site is organized in classes and the way the utilize them. and the way they create functions and process forms etc. Their coding does not match my standards, but again they argue that its matter of preference and as long as goal achieved the can be different way's to do it. I agree but their way is proven to have bugs and we spend a lot of time going back and forth with them to fix all problems security or functionality, yet they still write same code no matter how many times i asked them to stop doing certain things. Now i am ready to dismiss them but friend of mine told me that he has same exact problem with freelance developers he work with. So i don't want to trade one bad apple for another. Question is is there some world wide (or at least europe and usa) accepted standard or compliance on how write secure web based applications. What application architecture should be for maintainable application. Is there are some general standard that can be used for any language ruby php or java govern security and functionality and quality of code? Or at least for PHP and MySQL i use for my website. So i can make them follow this strict standard and stop making excuses.

• Retexturing a model via API on the web

  - by AndyMcKenna

  I'm looking at creating a site where a user could see our product and configure the options or look of it and see an image that represents that. The way I'm doing it now is if you have Piece A selected and then you choose Texture X, I have an image on the filesystem that is A with X applied to it. I just swap out my default image with that specific one. One product has 8 areas, with 10-70 pieces per area, and about 200 textures for each piece. Programming the site was pretty simple but we are getting bogged down in rendering all these pieces/textures and entering them into the system. What I would love to do is build a model and have some way to apply the textures via API and render it to the browser. I would even settle for exporting a flat image and pulling that into the browser. Is that possible with something like SolidWorks, 3DSMax, or something else? If the rendering is too time intensive it would still help to batch create all my images and use them the way I am currently.

• Advice on designing web application with a 40+ year lifetime

  - by user2708395

  Scenario Currently, I am apart of a health care project whose main requirement is to capture data with unknown attributes using user generated forms by health care providers. The second requirement is that data integrity is key and that the application will be used for 40+ years. We are currently migrating the client's data from the past 40 years from various sources (Paper, Excel, Access, etc...) to the database. Future requirements are: Workflow management of forms Schedule management of forms Security/Role based management Reporting engine Mobile/Tablet support Situation Only 6 months in, the current (contracted) architect/senior programmer has taken the "fast" approach and has designed a poor system. The database is not normalized, the code is coupled, the tiers have no dedicated purpose and data is starting to go missing since he has designed some beans to perform "deletes" on the database. The code base is extremely bloated and there are jobs just to synchronize data since the database is not normalized. His approach has been to rely on backup jobs to restore missing data and doesn't seem to believe in re-factoring. Having presented my findings to the PM, the architect will be removed when his contract ends. I have been given the task to re-architect this application. My team consists of me and one junior programmer. We have no other resources. We have been granted a 6-month requirement freeze in which we can focus on re-building this system. I suggested using a CMS system like Drupal, but for policy reasons at the client's organization, the system must be built from scratch. This is the first time that I will be designing a system with a 40+ lifespan. I have only worked on projects with 3-5 year lifespans, so this situation is very new, yet exciting. Questions What design considerations will make the system more "future proof"? What experiences have you had in designing such systems - both failures and successes? What questions should be asked to the client/PM to make the system more "future proof"?

• Web Crawler for Learnign Topics on Wikipedia

  - by Chris Okyen

  When I want to learn a vast topic on wikipedia, I don't know where to start. For instance say I want to learn about Binary Stars, I then have to know other things linked on that pages and linked pages on all the linked pages and so on for the specified number of levels. I want to write a web crawler like HTTracker or something similiar, that will display a heiarchy of the links on a certain page and the links on those linked pages.I wish to use as much prewritten code as possible. Here is an example: Pretending we are bending the rules by grabing links from only the first sentence of each pages The example archives and "processes" two levels deep The page is Ternary operation The First Level In mathematics a ternary operation is an N-ary operation The Second Level Under Mathmatics: Mathematics (from Greek µ???µa máthema, “knowledge, study, learning”) is the abstract study of topics encompassing quantity, structure, space, change and others; it has no generally accepted definition. Under N-ary In logic,mathematics, and computer science, the arity i/'ær?ti/ of a function or operation is the number of arguments or operands that the function takes Under Operation In its simplest meaning in mathematics and logic, an operation is an action or procedure which produces a new value from one or more input values ------------------------------------------------------------------------- I need some way to determine what oder to approach all these wiki pages to learn the concept ( in this case ternary operations )... Following along with this exmpakle, one way to show the path to read would a printout flowout like so: This shows that the first sentence of the Mathematics page doesn't link to the first sentence of pages linked on ternary page two levels deep. (Please tell me how I should explain this ) --- In otherwords, the child node of the top pages first sentence, ternary_operation, does not have any child nodes that reference the children of the top pages other children nodes- N-ary and operation. Thus it is safe to read this first. Since N-ary has a link to operations we shoudl read the operation page second and finally read the N-ary page last. Again, I wish to use as much prewritten code as possible, and was wondering what language to use and what would be the simpliest way to go about doing this if there isn't already somethign out there? Thank You!

• Where should "display functions" live in an MVC web app?

  - by User

  I'm using the Yii Framework which is an MVC php framework that is pretty similar to your standard web-based MVC framework. I want to display the related data from a many-to-many table as a list of strings in my view. Assuming a table schema like: tag { id, name } post { id, title, content, date } post_tag { post_id, tag_id } A post will display like: Date: 9/27/2012 Title: Some Title Content: blah blah blah... Tags: Smart Funny Cool Informative I can achieve this by doing something like this in my Post view: <?php echo join(' ', array_map(function($tag) { return $tag->name; }, $model->tags)); ?> (where $model->tags is an array of Tag objects associated with my model) My questions are: Is this amount of code/logic okay in the view? (Personally I think I'd rather just reference a property or call a single function.) If not, where should this code live? In the model? the controller? a helper? Potentially I may want to use in in other views as well. Ultimately I think its purely a display issue which would make me think it should be in the view, but then I have to repeat the code in any view I want to use it in.

• Should I learn the easier framework as a start? [closed]

  - by gunbuster363

  I've been a programmer for 2 years. I learned Java SE, C from college and learned Cobol from the workplace. I've noticed that there is a hype about framework and I actually don't know what is a framework. It is so cool that my colleague once said you cannot find a new job without knowing something like struct spring hibernate. And we should know Java EE too because it was aimed for enterprise application. I've never code something such as server-client web application, and I think I need to try it out. But which language should I code in? I can't decide between the following 2: 1) Java. It is heavily used by many company so I could easily reuse the experience gained. But Java and its related framework are pretty heavy (for the machine and operation). It is on-demand. 2) ROR. It is cool. The syntax of ruby is simple. I can get a better hand on it. And maybe I can learn the concept easily and possibly correctly. However, not much company here would use it. All the job ads are about J2EE/C#. Should I learn the easy one or the difficult one? Not to mention there are a lot of frameworks out there for Java, which makes the decision much more difficult.

• What's the canonical process for backing up a website?

  - by Walkerneo

  This is going to sound terrible, but bear with me. I currently have a cron job that does a mysql dump, a git add all and commit, and a git push to bitbucket. I set this up almost a year ago, when I didn't know much about git, backups, and general web development and administration. I haven't had the time to fix this and do it properly, but the repo has now grown quite big from accumulating large temporary files from my forum, so now I have to do something and I want to do it properly this time around. What processes do semi-large websites and personal site admins use for backing up server content? Based on what I've learned since I set this up, what I'm currently think of doing is: Making changes on a development domain and committing the code frequently Archiving the entire site after a successful deployment from the development domain Having automatic daily database and user-content backups. I still like the idea of backing up sqldumps with git, though. I know git isn't a backup tool and that this is beyond its purpose, but the textual queries that are exported would be easily managed by git and would save a lot of space in archives.

• Best way to protect website application code

  - by Gaz_Edge

  Background I have a web application that I host on my own server. I have clients who use the application as is, but some have asked if they can host the application on their own server. This enables them to have their own URLS rather than mine. The application only forms part of their website so I'm assuming it will not be possible for my server to respond to a direct call to their domain etc To give some examples, i currently have urls like www.mydomain.com/profile, www.mydomain.com/index.php?option=someoption&view=someview&id=1 What my clients' want is www.theirdomian.com/profile, www.theirdomian.com/index.php?option=someoption&view=someview&id=1 etc Question My question is, what is the best way for me to allow them to use their own URLs with my application, without giving them all the backend source code and databases to install on their server? One way I thought would be to create a router.php file that sits on their server. The router then asks my server to output the html. The router modifies all the links etc in the html source and outputs the new html through the clients server. When a link is clicked on the clients site, the router receives the request and modifies the url to get the data from my server etc. Is this an effective way to achieve what I want, or is it way off the mark.

• Web-Service: How much would you charge? [closed]

  - by jacksbox

  I´ve to make an offer to a client who wants me to develope a web-service for him. I have some trouble calculating the pricing - can you help me? Here is a rough outline of the project: It´s a portal on which various artists and entertainers can register and administrate there profile (texts, gallerie, some embedded videos, choose categories and radius of offer, etc). Other user can browse the artists by 3-4 level categories and countries/staats. If someone wants to hire a artists, he can put them in an "shopping-basket" and can mail everyone in his basket. The Artists can answer them with a form on the website (he doesn't get the email of the other person). Users should be able to comment/rate the artists. But if an artists wants this comments/ratings visible on his profile he must pay, and after that, the admin of the site must activate this comments/ratings. So, no more information given, what would you charge (ca.)? Edit: It´ll be developed with php/codeigniter. A .psd design is already there.

• What kind of security issues will I have if I provide my web app write access?

  - by iama

  I would like to give my web application write access to a particular folder on my web server. My web app can create files on this folder and can write data to those files. However, the web app does not provide any interface to the users nor does it publicize the fact that it can create files or write to files. Am I susceptible to any security vulnerabilities? If so, what are they?

• how to verify browser IP for server-side web service

  - by Anthony

  I have a web service that needs to be able to verify the end-user's IP that called the server-script that is requesting the web service. Simple layout: Person A goes to Webpage B. Webpage B calls Web Service C to get some info on Person A. Web Service C won't give Webpage B the requested information without confirmation that the request originated from Person A's IP and not someone who has stolen Person A's session. I'm thinking that for a browser-based solution, the original site (Webpage B) can open an iframe that goes to the Web Service's authentication page. A key of some kind is passed to the browser which will some how indicate both the user's IP and Web Page B's IP, so that the Web Service can confirm that no one has nabbed anything. I have two challenges, but I'll stick to the more immediate one first: I'm not sure if my browser-based plan really makes sense. If someone steals the session cookie, how is the Web Service going to know? Would this cookie be held be Web Page B and thus be harder to steal? Is it a sound assumption that a cookie or key held by the server only and not the browser is safe? Also, would the web service, based on the iframe initial connection, be expecting the server/user-ip combo? What I mean is, does the session key provided via the iframe get stored by the web service and the Web Site B shows it has a match? Or is the session key more generic, meaning the web service is passed the key by Website B and the Web Service verifies that this is a valid session key based on what a valid session key should look like?

• Should I be an algorithm developer, or java web frameworks type developer?

  - by Derek

  So - as I see it, there are really two kinds of developers. Those that do frameworks, web services, pretty-making front ends, etc etc. Then there are developers that write the algorithms that solve the problem. That is, unless the problem is "display this raw data in some meaningful way." In that case, the framework/web developer guy might be doing both jobs. So my basic problem is this. I have been an algorithms kind of software developer for a few years now. I double majored in Math and Computer science, and I have a master's in systems engineering. I have never done any web-dev work, with the exception of a couple minor jobs, and some hobby level stuff. I have been job interviewing lately, and this is what happens: Job is listed as "programmer- 5 years of experience with the following: C/C++, Java,Perl, Ruby, ant, blah blah blah" Recruiter calls me, says they want me to come in for interview In the interview, find out they have some webservices development, blah blah blah When asked in the interview, talk about my experience doing algorithms, optimization, blah blah..but very willing to learn new languages, frameworks, etc Get a call back saying "we didn't think you were a fit for the job you interviewed wtih, but our algorithm team got wind of you and wants to bring you on" This has happened to me a couple times now - see a vague-ish job description looking for a "programmer" Go in, find out they are doing some sort of web-based tool, maybe with some hardcore algorithms running in the background. interview with people for the web-based tool, but get an offer from the algorithms people. So the question is - which job is the better job? I basically just want to get a wide berth of experience at this level of my career, but are algorithm developers so much in demand? Even more so than all these supposed hot in demand web developer guys? Will I be ok in the long run if I go into the niche of math based algorithm development, and just little to no, or hobby level web-dev experience? I basically just don't want to pigeon hole myself this early. My salary is already starting to get pretty high - and I can see a company later on saying "we really need a web developer, but we'll hire this 50k/year college guy, instead of this 100k/year experience algorithm guy" Cliffs notes: I have been doing algorithm development. I consider myself to be a "good programmer." I would have no problem picking up web technologies and those sorts of frameworks. During job interviews, I keep getting "we think you've got a good skillset - talk to our algorithm team" instead of wanting me to learn new skills on the job to do their web services or whhatever other new technology they are doing. Edit: Whenever I am talking about algorithm development here - I am talking about the code that produces the answer. Typically I think of more math-based algorithms: solving a financial problem, solving a finite element method, image processing, etc

• Advantages and disadvantages of building a single page web application

  - by ryanzec

  I'm nearing the end of a prototyping/proof of concept phase for a side project I'm working on, and trying to decide on some larger scale application design decisions. The app is a project management system tailored more towards the agile development process. One of the decisions I need to make is whether or not to go with a traditional multi-page application or a single page application. Currently my prototype is a traditional multi-page setup, however I have been looking at backbone.js to clean up and apply some structure to my Javascript (jQuery) code. It seems like while backbone.js can be used in multi-page applications, it shines more with single page applications. I am trying to come up with a list of advantages and disadvantages of using a single page application design approach. So far I have: Advantages All data has to be available via some sort of API - this is a big advantage for my use case as I want to have an API to my application anyway. Right now about 60-70% of my calls to get/update data are done through a REST API. Doing a single page application will allow me to better test my REST API since the application itself will use it. It also means that as the application grows, the API itself will grow since that is what the application uses; no need to maintain the API as an add-on to the application. More responsive application - since all data loaded after the initial page is kept to a minimum and transmitted in a compact format (like JSON), data requests should generally be faster, and the server will do slightly less processing. Disadvantages Duplication of code - for example, model code. I am going to have to create models both on the server side (PHP in this case) and the client side in Javascript. Business logic in Javascript - I can't give any concrete examples on why this would be bad but it just doesn't feel right to me having business logic in Javascript that anyone can read. Javascript memory leaks - since the page never reloads, Javascript memory leaks can happen, and I would not even know where to begin to debug them. There are also other things that are kind of double edged swords. For example, with single page applications, the data processed for each request can be a lot less since the application will be asking for the minimum data it needs for the particular request, however it also means that there could be a lot more small request to the server. I'm not sure if that is a good or bad thing. What are some of the advantages and disadvantages of single page web applications that I should keep in mind when deciding which way I should go for my project?

• Can I disallow printing with parent controls on Snow Leopard?

  - by Quinn Taylor

  I have two children under 4 who are quite computer-savvy, and have their own account managed by parental controls to restrict what they can do an see. However, I haven't found a way to disallow them from printing, and I'm looking for a way do so. Their pictures of Sesame Street and Word World are cute and all, but I'd like to be in control of what (or even if) they print. (Our printer is connected wirelessly, not directly to the Mac.) I know I can add more time or authorize use of a given application by providing my password — can I do something similar for printing, such as approving or denying particular print jobs?
