  • Structuring System Architecture in a Flex Web Application on a Budget (w/o Java)

    - by phwd
    I started a project a while back using the following architecture from Adobe Developer Article talking about Creating marketing platforms in Flex. I did my first set of coding locally forgetting that my server did not handle Tomcat. So I said okay, and cut some corners and then some other limitation came up and I cut some more corners. Eventually for a good week or two, it was trying to get the project working with making the ends meet. Layers started to merge. In the end I used a PureMVC (Presentation/Client) - ZendAMF (Communication) - MySql (Data) Layout. It worked but I never felt as though I had some layer just to take care of all the SQL calls to the data.It just felt hacked together So should I keep the above setup and just start from the presentation layer and move downwards like they said in the article or is there a better layering (based on a hosting plan that does not handle Java) I could accomplish ? NOTE: I would just ask the adobe guys but they barely reply on their site. Thanks !

  • Axis2 issue with comment in WSDL

    - by Sirs
    I'm using an Axis2 client to access an external Webservice, whose WSDL starts with the following content: <?xml version="1.0" encoding="UTF-8"?><!--Created by TIBCO WSDL--><wsdl:definitions xmlns:wsdl=... My call to sendReceive crashes with the following error: com.ctc.wstx.exc.WstxUnexpectedCharException: Unexpected character 'C' (code 67) in prolog; expected '<' The 'C' is the first character on the comment in the WSDL. Without that comment everything works fine, but as far as my knowledge of basic XML dictates that comment is correct. My question would be: Is this a bug in Axis2 or is the accessed WSDL malformed? Is there any way to prevent Axis2 from crashing under these circumstances?

  • How to make iPhone application accept incorrect server certificate but only specific one?

    - by Igor Romanov
    I need to work with private HTTPS API and client has incorrect certificate on the host. Certificate is for www.clienthost.com and I'm working with api.clienthost.com. So I need to connect via HTTPS to api.clienthost.com ignoring incorrect certificate but still make sure it is the one for www.clienthost.com and not something else. I found this answer: http://stackoverflow.com/questions/933331/how-to-use-nsurlconnection-to-connect-with-ssl-for-an-untrusted-cert and it seems to solve half of my problem but I'm trying to figure out how to still check certificate for host is one I expect to see and not different.

  • Web Application Nat Traversal

    - by pbreault
    We are deploying web applications in java using tomcat on client machines across the country. Once they are installed, we want to allow a remote access to these web applications through a central server, but we do not want our clients to have to open ports on their routers. Is there a way to tunnel the http traffic in a way that the central server can access the web application that is behind the firewall ? The central server has a static ip address and we have full control over it. We don't need to access the filesystem, we only want to access the web application itself through a browser.

  • Javascript Hex String to Image

    - by Gunnar Hoffman
    Hello everyone. I'll cut right to the chase. Right now I am developing a web based application. It has a PHP REST based architecture that serves up XML documents. On many of these documents attributes are hex encoded picture strings. On the client side jQuery AJAX fetches an XML document with a picture in it. I need to display said picture in some <img> tags. However my knowledge on such methods is lacking so here I am asking for help. Goal: JavaScript String variable in hex or base64 HTML displayed image. Cross browser is required, or a hack for the ones that do not support it is fine. Thanks, Gunnar

  • Should I be so enthusiastic about Groovy?

    - by rukoche
    I'm currently working on my project which consists of front and back-end written in PHP and desktop app written in Java, and that's what the plan was before I discovered Groovy and later on Grails. Now after rewriting my desktop client and sketching some back-end functionality in Groovy I'm considering to drop PHP altogether in favor of Groovy (although I haven't played around with Grails yet.) For me it just looks like coding in Groovy is as simple as in PHP, but with lots of extra sugar and awesomeness of Java libraries. Comparing those two may sound awkward, but hey I'm an amateur ;) Finally to my question, from the looks of it most of the articles/blog posts about Groovy I can find is awfully outdated. Am I missing some reason why it's not so popular and which will crush my enthusiasm to bits? :D

  • A reasonable way to add attributes to an xml root element.

    - by DrLazer
    The function "WriteStartElement" does not return anything. I find this a little bizzare. So up until now I have been doing it like this. XmlDocument xmlDoc = new XmlDocument(); XmlTextWriter xmlWriter = new XmlTextWriter(m_targetFilePath, System.Text.Encoding.UTF8); xmlWriter.Formatting = Formatting.Indented; xmlWriter.WriteProcessingInstruction("xml", "version='1.0' encoding='UTF-8'"); xmlWriter.WriteStartElement("client"); xmlWriter.Close(); xmlDoc.Load(m_targetFilePath); XmlElement root = xmlDoc.DocumentElement; Saving the doc, then reloading it to get hold of the start element so i can write attributes to it. Does anybody know the correct way of doing this because I'm pretty sure what I'm doing isn't right. I tried to use xmlWriter.AppendChild() but it doesnt seem to write out anything. :(

  • noindex, follow on list views?

    - by Fabrizio
    On one of our client's website we have lot's of list views with links to detail views. (Image a blog with the posts overview and the single pages). The detail views don't change, but the list views will change when new items come up. The pages displaying the list view don't contain any other valuable content. So my question is: Does it make sense to define meta "noindex, follow" on the list view pages (and of course "index, follow" on the detail views) to prevent search engines to point to the list views when the keyword is found in the title or teaser of the list view. By the time the visitor clicks on the list view search result it might have changed and the content is not visible anymore, whereas if he goes directly to the single view he will definitly find what he was searching for? Related question: The startpage also contains mainly a list view. Is it a bad idea to have the start page not indexed? Any SEO gurus here? :) Thanks, Fabrizio.

  • How to capture a screen shot in .NET from a webapplication?

    - by CodeToGlory
    In Java we can do it as follows: import java.awt.Dimension; import java.awt.Rectangle; import java.awt.Robot; import java.awt.Toolkit; import java.awt.image.BufferedImage; import javax.imageio.ImageIO; import java.io.File; ... public void captureScreen(String fileName) throws Exception { Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize(); Rectangle screenRectangle = new Rectangle(screenSize); Robot robot = new Robot(); BufferedImage image = robot.createScreenCapture(screenRectangle); ImageIO.write(image, "png", new File(fileName)); } ... How do we do this in .NET from a webapplication? Capturing the client's screen and sending it to the server all from within the application.

  • GAE and Socket Data

    - by Vinod
    I have a field device which keeps on sending data over to any designated port using sockets. I am planning to use GAE for server-side infrastructure. I read GAE does not support sockets. But i can configure the device to send the data over port 80. so we wrote a genericservlet to capture this data on GAE. But it is not obtaining any values from the client. any suggestions to fix this issue?

  • More interactive ZODB packing

    - by Mikko Ohtamaa
    Hi, Current ZMI management "Pack database" functionality is little rough. 1) Could it be possible to have some kind of progress indicator for web UI? E.g. one telling how many minutes/hours are left giving at least some kind of estimate 2) How does ZODB packing affect the responsivity of the site? Are all transactions blocked? 3) Any command line scripts with progress indicator available so you could do this from a ZEO command line client? 4) At least some kind of log markers to logout output... [INFO] 30% done... 3:15 to go

  • Authorization in a more purely OOP style...

    - by noblethrasher
    I've never seen this done but I had an idea of doing authorization in a more purely OO way. For each method that requires authorization we associate a delegate. During initialization of the class we wire up the delegates so that they point to the appropriate method (based on the user's rights). For example: class User { private deleteMemberDelegate deleteMember; public StatusMessage DeleteMember(Member member) { if(deleteMember != null) { deleteMember(member); } } //other methods defined similarly... User(string name, string password) //cstor. { //wire up delegates based on user's rights. //Thus we handle authentication and authorization in the same method. } } This way the client code never has to explictly check whether or not a user is in a role, it just calls the method. Of course each method should return a status message so that we know if and why it failed. Thoughts?

  • Is there a way for IIS6 to do http and https together in the same site?

    - by puffpio
    The site needs to be accessible both from HTTP and HTTPS (in case the client wants the form submissions to be secure or not) The site is hosted in IIS6 and ideally I'd like to be able to just have one website in there and it can handle both http and https..is this possible? alternatively i was thinking maybe creating a "secure" subdirectory in the site and duplicating everything in there as well..is that feasible? this is further complicated that it is using asp.net 3.5's routing ability to do url rewrites so even if I create a secure subdirectory, i dunno if it will actually pick up that it's supposed to be SSL approved

  • How do people handle working with Code Names for their projects?

    - by Mark
    Hi All, Recently we started using some code names for several different types of prototype applications all following a theme. This made things a little more fun and was a great idea. The problem is that Im not too sure how people deal with migrating a codebase from "codename" state into version 1.0 state which may have a proper name... not something that a client really shouldnt see :) We are using Visual Studio at the moment, and I can see that you can change the assembly name, but there are references to the namespaces, etc... that would really be a large change to make. Do people both changing things like namespaces before the v1.0 release?

  • building a web application in eclipse

    - by Noona
    As a concluding assignment for the technologies taught in a data management course, we have to write a web application using the technologies taught throughout the course, this mostly includes xhtml, css, JSP, servelets, JDBC, AJAX, webservices. the project will eventually be deployed using tomcat. we are given the option of choosing the technologies that we see fit. since this is my first time developing a web application I am having some uncertainties about where to start, so for example now I am writing the object classes that will be used in the database and implementing the operations that will be performed on the database, but I am not sure about how to make these operations available to a client through the website, I mean I think I have to write a servlet through which I can extract the request parameters and set the response accordingly, but I would still like a more specific overview of what I am going to do, so if someone can link me to a tutorial with an example that makes use of these technologies while illustrating the stages of the design so that I can see how all these things are linked together in a web project. thanks

  • accessing pdf via https URL

    - by Paul
    I send out a newsletter email containing URLs to a https website that then redirects to a pdf document. On first invocation of a URL the user is prompted with the typical https browser "security alert" popup, on selecting "Yes" the display of the PDF fails. The HTTP Header on the failed response is: HTTP/1.1 200 OK Server: ECS/HTTP-Server Date: Tue, 16 Mar 2010 15:57:26 GMT Content-type: application/pdf Content-language: en-US Set-cookie: JSESSIONID=0000r111cRz1Vc-PtCJg8Cdu4eR:-1; Path=/ Expires: Thu, 01 Dec 1994 16:00:00 GMT Cache-control: no-cache="set-cookie, set-cookie2" Connection: close Subsequent invocations of the URL successfully opens the PDF (at this point we have the session id cookie set by the initial failed request). The HTTP Header on the successful response is: HTTP/1.1 200 OK Server: ECS/HTTP-Server Date: Tue, 16 Mar 2010 16:53:03 GMT Content-type: application/pdf Content-language: en-US Connection: close The email client is Lotus Notes 6.5 which launches an IE6 browser Any ideas?

  • Managing multiple WCF endpoints for the same service

    - by Jacob
    I am building an single application that uses WCF to call out to multiple external endpoints. All of the remote endpoints are identical except for the URI. I would like to treat them as a pool: add and remove endpoints through configuration and have the application understand what to do. My original plan was to define one endoint in the app.config, then iterate over my list of endpoints and update client.Endpoint.Address on the fly to point to the right place. Unfortunately, that property is read-only, rendering that plan unworkable. I'm a little bit stumped here. Any suggestions on how I might accomplish this?

  • How is 'processing credit card data' defined (PCI)?

    - by Chris
    If i have a web application and i receive credit card data transmitted via a POST request by a web browser over HTTPS and instantly open a socket (SSL) to a remote PCI compilant card processor to forward the data and wait for a response, am i allowed to do that? or is this receiving the data with my application and forwarding it already subject of "processing credit card data"? if i create an iframe that is displayed in a client browser to enter cc data and this iframe posts the data via HTTPS to remote card processor (directly!) is this already a case of processing credit card data? even if my application code 'doesnt touch' the entered data with any event handlers? i'm interested in the definition "credit card data processing". when does it start to be a cc data processing application? can somebody maybe point me to that section in PCI-DSS standard that clearly defines when you start to 'be a processing application'? Thanks,

  • Android P2P Multiplayer game (with a) XMPP/Google talk b) JXTA peerdroid c) other way)

    - by Kristof
    Hi, I am an android developer and I made some board games. Now i want to make some of my board games multiplayer. I don't want to create and host my own web service, so i thought about P2P. The first thing i found was the XMPP protocol, however it's not real P2P, but if i can use the existing google talk service, i'm ready to go. Is this possible while using your existing google account without interfering with the normal working of your google talk client? Then i heard about JXTA, a real P2P solution, and it's already ported from J2ME to Android (http://code.google.com/p/peerdroid/). Maybe i am overcomplexing things here (as i do sometimes) I just want to know the easiest way to do simple P2P for a boardgame. All your opinions are welcome! Thanks in advance

  • Recommendations for supporting both Oracle and SQL Server in the same ASP.NET app with NHibernate

    - by Hugo Zapata
    Our client wants to support both SQL Server and Oracle in the next project. Our experience comes from .NET/SQL Server platform. We will hire an Oracle developer, but our concern is with the DataAccess code. Will NHibernate make the DB Engine transparent for us? I don't think so, but i would like to hear from developers who have faced similar situations. I know this question is a little vague, because i don't have Oracle experience, so i don't know what issues we will find.

  • How to setup Xcode 3.1.4 with Perforce ?

    - by Azeworai
    Hi everyone, I've been trying to setup Xcode with Perforce for about 7 hours now and managed to get the Perforce Repository Authenticated within Xcode. The problem I have is, within the repositories window, I don't see any directories for me to check out. I can see the p4root login and client are ok with the tick on the repository log. When I try to Import an xcode project directory within the Perforce root directory- the import fails with '/Users/jackson/p4root/alpha/MessageTapper' is not under the Perforce root. I have p4d running on the local machine, and have created a user and workspace. The workspace has the directories in view. I'm hoping for someone to give me some direction or maybe point me to a good reference to how to set perforce up with xcode. Thanks!
