• HTTP Error 403.18 - Forbidden - asp.net mvc web api

  - by CoffeeCode

  I have deployed the default asp.net mvc 4 web api project to my windows server 2008 RC and am experiensing some issues with calling the web api actions. I'm quite new in the server/iis configuration part. I can open the home page, but the API part doesnt work. I'm getting such an error: HTTP Error 403.18 - Forbidden The specified request cannot be processed in the application pool that is configured for this resource on the Web server Module IIS Web Core Notification BeginRequest Handler StaticFile Error Code 0x00000000 Requested URL http://server.com:80/index.php?p=MvcApplication2_deploy/api/values/ Physical Path C:\Inetpub\vhosts\server.com\Webservice\index.php Logon Method Not yet determined Logon User Not yet determined I have checked Url Rewrite it is empty, have disabled WebDAV and also checked the Handler Mappings every thing seems to be ok there. Could any one give me some hints what could be wrong? Thanks!!!

• Configure IIS7.5 to allow calls to asmx web services.

  - by goodeye

  Hi, I migrated a site from IIS6 to Windows Server 2008 R2 IIS7.5. It has an asmx web service, which is working fine locally, but returns this 500 error when called from another machine: Request format is unrecognized for URL unexpectedly ending in /myMethodName The solution in previous versions is to add this to the web.config for the protocols needed (typically omitting HttpGet for production): <system.web> <webServices> <protocols> <add name="HttpGet" /> <add name="HttpPost" /> <add name="HttpSoap" /> </protocols> </webServices> </system.web> This is posted everywhere, including http://stackoverflow.com/questions/657313/request-format-is-unrecognized-for-url-unexpectedly-ending-in For IIS7.5, this throws a configuration error; I understand this section doesn't belong, but tried it anyway. I also boiled down the asmx call to a simple hello world. I tested with POST also, just to eliminate any issues with GET. What is the equivalent for IIS7.5? - either web.config format or the UI button to push would be really helpful. Thanks, Bob

• Why don't I have a "Web Service References" menu item in excel/VBA?

  - by Draemon

  I'm trying to consume a SOAP web service from excel. Now according to This article (and confirmed by other articles and MSDN) if I do the following: Install the web services toolkit (I've installed v2.01) Install SOAP Toolkit 3.0 Add a reference to Microsoft Soap Type Library (I've tried v3.0 and an older one) I should get a "Web Service References" menu item in the Tools menu but I don't. I've also tried adding every reference that seemed to have anything to do with SOAP or XML, but it hasn't helped. Any ideas?

• What SDK I should choose on Amazon Web Service to build API on server app?

  - by Nguyen Minh Binh

  I am a newbie on Amazon Web Service. I have a task that setup then build a web service that provide APIs to Mac OS, iOS, Android client. There are some APIs and Database need to be kept in secure.

Not yet, there are 2 special SDK for Android and iOS app. So, What should I choose (Java, .Net, PHP,...) to carry out my task? Does AWS support all webservice protocol? Does it support secure webservice? Thanks a lot.

• Deploying web services on a RHEL 5 box using Apache/Tomcat/Axis/Java.

  - by Deepak Konidena

  Hi, I am new to the Web services scene. I currently have access to a RHEL5 box and i need to deploy a java web service on it. It runs apache and i know this because i have a website hosted on this machine. Now, i want to deploy a web service on to this website to be able to just pass a link to someone when they need to access my web service. Could someone point out a resource or explain what all i need to get the webservice deployed using Tomcat/Apache Axis and Java. I have done this on Windows (hosted on localhost) but couldn't quite figure out things on linux. Any help is greatly appreciated. Thanks. Deepak.

• What would be the total expenses of running an in-home web server?

  - by techaddict

  I have several hosting accounts with companies, and plan to keep them. However, I would like to try my hand at creating my own home web-server, both for fun and for the learning experience. I would like to know the expenses involved, including: electricity costs (greater than light bulb?) internet costs (will I have to upgrade my internet? Or is 3-5Mbps upload speed fine for a web server with medium amount of traffic? Would I have to get a separate internet connection?) other unknown expenses Consider that I will configure the web server myself, so that is not an expense. Also consider that I already have a computer (year-old Dell laptop, 15R) to use to be dedicated as the web server.

• Throttle connections to web service if load gets too high?

  - by Joseph Turian

  I have a web site that communicates via XMLRPC with an XMLRPC server web service. (The web service is written in Python using xmlrpclib.) I believe that xmlrpclib will block while it is handling one request. So if there are three users with an xmlrpclib request ahead of you, your response takes four times as long. How do I handle it if I receive too many XMLRPC requests and the web service gets bogged down and has slow response time? If I am getting slashdotted, my preferred behavior is that the first users get good response times and everyone else is told to come back later. I think this is superior to giving everyone terrible response times. How do I create this behavior? Is this called load-balancing? I am not actually balancing though, until I have multiple servers.

• Tools to manage large network of heterogeneous web applications?

  - by Andrew

  I recently started a new job where I've been tasked with managing a global network of heterogenous web applications. There's very little documentation. My first order of business is to create an inventory of all of the web applications. Are there any tools out there to manage a large group of web apps? I'd like to collect a large dataset for each website including: logins for web based control panels logins to FTP/ssh accounts Google analytics tracking code for each site 3rd party libraries used SSL certs, issuers, and expiration dates etc I know I could keep the information in Excel or build a custom database, but I'm hoping there's already a tool out there to help me with this.

• Clipboard app that automatically saves to Web share folder ?

  - by cyberpine

  I currently use SnagIt and have used Windows 7 Snipping tools. These tools allow you to copy a piece of your screen the clipboard and then paste it into other applications on your desktop. They work with Outlook and it's really useful as you don't have to save the image to do a write-up or send an email. Problem is - you can't paste clipboard images into webforms. Gmail web does have image insert feature, but it only works on web images that you copied as it extracts the full url from your copy and uses that. It does not work on with images in your local clipboard. Does anybody know of an application that would allow to clip and save directly to a web folder, maybe something that replaces your clipboard with the URL of the save image location? It would be awesome if the picasa web client or evernote allowed actual clipboard pasting. Instead they ask for a file to upload.

• Provider claiming "all web servers in the cloud are automatically kept in sync" - should I be skeptical?

  - by RobMasters

  I'm no expert in cloud computing - I've spent a fair bit of time researching it and various providers but am yet to get any hands-on experience with it. From what I've read about AWS and auto-scaling EC2 instances though, it seems as though each instance should be completely decoupled from all other instances. i.e. If content is uploaded to the web server's local filesystem from a custom CMS backend then that content won't be available if subsequently requested from a different web server in the auto-scaling group. Is that right? I met with a representative of our existing hosting provider recently and he was claiming that it isn't a problem that our legacy CMS system is highly dependent on having a local filesystem. He said that all web servers, regardless of how many, would be kept as exact duplicates so I shouldn't notice any difference compared to our existing setup of a single dedicated server. This smells a little too much like bull fecal-matter to me...should I be skeptical about this? I'm a little worried because my (non-technical) boss who ultimately makes the decisions is all for signing up to this cloud solution because it won't require any extra work. I'm sure that they must at least be able to provide this, otherwise they wouldn't be attempting to sell it to us. But at what cost? It sounds as though each web server will always need to be checking the other web server(s) for new static content, which to me sounds like unwanted overhead that'll slow things down. I'd really appreciate it if somebody could clear this up to me. I'm all for switching to AWS and using S3+CloudFront for all static content, but that isn't looking very likely to happen at the moment.

• Securing Web Service communication with SSL using CXF

  Hi all, I am trying to secure communications via SSL/TLS for one of our Web Service using CXF 2.2.5.

• How to return a complex object from an axis web service

  - by jani

  Hi all, I am writing a simple web service to return an object with 2 properties. I am embedding the service into an existing web application. My wsdd looks like this. <globalConfiguration> <parameter name="adminPassword" value="admin"/> <parameter name="sendXsiTypes" value="true"/> <parameter name="sendMultiRefs" value="true"/> <parameter name="sendXMLDeclaration" value="true"/> <parameter name="axis.sendMinimizedElements" value="true"/> <requestFlow> <handler type="java:org.apache.axis.handlers.JWSHandler"> <parameter name="scope" value="session"/> </handler> <handler type="java:org.apache.axis.handlers.JWSHandler"> <parameter name="scope" value="request"/> <parameter name="extension" value=".jwr"/> </handler> </requestFlow> </globalConfiguration> <handler name="LocalResponder" type="java:org.apache.axis.transport.local.LocalResponder"/> <handler name="URLMapper" type="java:org.apache.axis.handlers.http.URLMapper"/> <handler name="Authenticate" type="java:org.apache.axis.handlers.SimpleAuthenticationHandler"/> <transport name="http"> <requestFlow> <handler type="URLMapper"/> <handler type="java:org.apache.axis.handlers.http.HTTPAuthHandler"/> </requestFlow> </transport> <transport name="local"> <responseFlow> <handler type="LocalResponder"/> </responseFlow> </transport> <service name="helloService" provider="java:RPC" style="document" use="literal"> <parameter name="className" value="ws.example.HelloService"/> <parameter name="allowedMethods" value="*"/> <parameter name="scope" value="application"/> </service> I am able to deploy it successfully.

• What is my HttpContext.GetLocalResourceObject Method Virtual Path?

  - by ARUNRAJ

  I have read http://msdn.microsoft.com/en-us/library/ms149953.aspx and need to verify what is my GetLocalResourceObject virtual path. My local resource files are located on my pc at: C:\inetpub\wwwroot\GlobalX\Input\App_LocalResources Within this folder are my resource files for all the languages that site handles (InputContactDetails.aspx.ro.resx, InputContactDetails.aspx.hi.resx, etc.), as well as the default resource file (InputContactDetails.aspx.resx). I am receiving an error when I attempt to implement the virtual path string. Below is my line of offending code: return '<%= HttpContext.GetLocalResourceObject("~/GlobalX/Input/App_LocalResources/InputContactDetails.aspx.resx", "ContactDetails.Text", new System.Globalization.CultureInfo("ro")) %>'; I have tried ~/GlobalX/Input/App_LocalResources as the virtual path, and several other permutations, but I get the same error. If someone could show what I am doing wrong, I would appreciate it greatly. Here is the error message I am getting: The resource class for this page was not found.

• jQuery AutoComplete (jQuery UI 1.8rc3) with ASP.NET web service

  - by user296640

  Currently, I have this version of the autocomplete control working when returning XML from a .ashx handler. The xml looks like this: <?xml version="1.0" encoding="UTF-8" standalone="no" ?> <States> <State> <Code>CA</Code> <Name>California</Name> </State> <State> <Code>NC</Code> <Name>North Carolina</Name> </State> <State> <Code>SC</Code> <Name>South Carolina</Name> </State> The autocomplete code looks like this: $('.autocompleteTest').autocomplete( { source: function(request, response) { var list = []; $.ajax({ url: "http://commonservices.qa.kirkland.com/StateLookup.ashx", dataType: "xml", async: false, data: request, success: function(xmlResponse) { list = $("State", xmlResponse).map(function() { return { value: $("Code", this).text(), label: $("Name", this).text() }; }).get(); } }); response(list); }, focus: function(event, ui) { $('.autocompleteTest').val(ui.item.label); return false; }, select: function(event, ui) { $('.autocompleteTest').val(ui.item.label); $('.autocompleteValue').val(ui.item.value); return false; } }); For various reasons, I'd rather be calling an ASP.NET web service, but I can't get it to work. To change over to the service (I'm doing a local service to keep it simple), the start of the autocomplete code is: $('.autocompleteTest').autocomplete( { source: function(request, response) { var list = []; $.ajax({ url: "/Services/GeneralLookup.asmx/StateList", dataType: "xml", This code is on a page at the root of the site and the GeneralLookup.asmx is in a subfolder named Services. But a breakpoint in the web service never gets hit, and no autocomplete list is generated. In case it makes a difference, the XML that comes from the asmx is: <?xml version="1.0" encoding="utf-8" ?> <string xmlns="http://www.kirkland.com/"><State> <Code>CA</Code> <Name>California</Name> </State> <State> <Code>NC</Code> <Name>North Carolina</Name> </State> <State> <Code>SC</Code> <Name>South Carolina</Name> </State></string> Functionally equivalent since I never use the name of the root node in the mapping code. I haven't seen anything in the jQuery docs about calling a .asmx service from this control, but a .ajax call is a .ajax call, right? I've tried various different paths to the .asmx (~/Services/), and I've even moved the service to be in the same path to eliminate these issues. No luck with either. Any ideas?

• REST web service keeps first POST parametrs

  - by Diego

  I have a web service in REST, designed with Java and deployed on Tomcat. This is the web service structure: @Path("Personas") public class Personas { @Context private UriInfo context; /** * Creates a new instance of ServiceResource */ public Personas() { } @GET @Produces("text/html") public String consultarEdad (@QueryParam("nombre") String nombre) { ConectorCliente c = new ConectorCliente("root", "cafe.sql", "test"); int edad = c.consultarEdad(nombre); if (edad == Integer.MIN_VALUE) return "-1"; return String.valueOf(edad); } @POST @Produces("text/html") public String insertarPersona(@QueryParam("nombre") String msg, @QueryParam("edad") int edad) { ConectorCliente c = new ConectorCliente("usr", "passwd", "dbname"); c.agregar(msg, edad); return "listo"; } } Where ConectorCliente class is MySQL connector and querying class. So, I had tested this with the @GET actually doing POST work, any user inputed data and information from ma Java FX app and it went direct to webservice's database. However, I changed so the CREATE operation was performed through a webservice responding to an actual POST HTTP request. However, when I run the client and add some info, parameters go OK, but in next time I input different parameters it'll input the same. I run this several times and I can't get the reason of it. This is the clients code: public class WebServicePersonasConsumer { private WebTarget webTarget; private Client client; private static final String BASE_URI = "http://localhost:8080/GetSomeRest/serviciosweb/"; public WebServicePersonasConsumer() { client = javax.ws.rs.client.ClientBuilder.newClient(); webTarget = client.target(BASE_URI).path("Personas"); } public <T> T insertarPersona(Class<T> responseType, String nombre, String edad) throws ClientErrorException { String[] queryParamNames = new String[]{"nombre", "edad"}; String[] queryParamValues = new String[]{nombre, edad}; ; javax.ws.rs.core.Form form = getQueryOrFormParams(queryParamNames, queryParamValues); javax.ws.rs.core.MultivaluedMap<String, String> map = form.asMap(); for (java.util.Map.Entry<String, java.util.List<String>> entry : map.entrySet()) { java.util.List<String> list = entry.getValue(); String[] values = list.toArray(new String[list.size()]); webTarget = webTarget.queryParam(entry.getKey(), (Object[]) values); } return webTarget.request().post(null, responseType); } public <T> T consultarEdad(Class<T> responseType, String nombre) throws ClientErrorException { String[] queryParamNames = new String[]{"nombre"}; String[] queryParamValues = new String[]{nombre}; ; javax.ws.rs.core.Form form = getQueryOrFormParams(queryParamNames, queryParamValues); javax.ws.rs.core.MultivaluedMap<String, String> map = form.asMap(); for (java.util.Map.Entry<String, java.util.List<String>> entry : map.entrySet()) { java.util.List<String> list = entry.getValue(); String[] values = list.toArray(new String[list.size()]); webTarget = webTarget.queryParam(entry.getKey(), (Object[]) values); } return webTarget.request(javax.ws.rs.core.MediaType.TEXT_HTML).get(responseType); } private Form getQueryOrFormParams(String[] paramNames, String[] paramValues) { Form form = new javax.ws.rs.core.Form(); for (int i = 0; i < paramNames.length; i++) { if (paramValues[i] != null) { form = form.param(paramNames[i], paramValues[i]); } } return form; } public void close() { client.close(); } } And this this the code when I perform the operations in a Java FX app: String nombre = nombreTextField.getText(); String edad = edadTextField.getText(); String insertToDatabase = consumidor.insertarPersona(String.class, nombre, edad); So, as parameters are taken from TextFields, is quite odd why second, third, fourth and so on POSTS post the SAME.

• R: extracting "clean" UTF-8 text from a web page scraped with RCurl

  - by SlowLearner

  Using R, I am trying to scrape a web page save the text, which is in Japanese, to a file. Ultimately this needs to be scaled to tackle hundreds of pages on a daily basis. I already have a workable solution in Perl, but I am trying to migrate the script to R to reduce the cognitive load of switching between multiple languages. So far I am not succeeding. Related questions seem to be this one on saving csv files and this one on writing Hebrew to a HTML file. However, I haven't been successful in cobbling together a solution based on the answers there. The pages are from Yahoo! Japan Finance and my Perl code that looks like this. use strict; use HTML::Tree; use LWP::Simple; #use Encode; use utf8; binmode STDOUT, ":utf8"; my @arr_links = (); $arr_links[1] = "http://stocks.finance.yahoo.co.jp/stocks/detail/?code=7203"; $arr_links[2] = "http://stocks.finance.yahoo.co.jp/stocks/detail/?code=7201"; foreach my $link (@arr_links){ $link =~ s/"//gi; print("$link\n"); my $content = get($link); my $tree = HTML::Tree->new(); $tree->parse($content); my $bar = $tree->as_text; open OUTFILE, ">>:utf8", join("","c:/", substr($link, -4),"_perl.txt") || die; print OUTFILE $bar; } This Perl script produces a CSV file that looks like the screenshot below, with proper kanji and kana that can be mined and manipulated offline: My R code, such as it is, looks like the following. The R script is not an exact duplicate of the Perl solution just given, as it doesn't strip out the HTML and leave the text (this answer suggests an approach using R but it doesn't work for me in this case) and it doesn't have the loop and so on, but the intent is the same. require(RCurl) require(XML) links <- list() links[1] <- "http://stocks.finance.yahoo.co.jp/stocks/detail/?code=7203" links[2] <- "http://stocks.finance.yahoo.co.jp/stocks/detail/?code=7201" txt <- getURL(links, .encoding = "UTF-8") Encoding(txt) <- "bytes" write.table(txt, "c:/geturl_r.txt", quote = FALSE, row.names = FALSE, sep = "\t", fileEncoding = "UTF-8") This R script generates the output shown in the screenshot below. Basically rubbish. I assume that there is some combination of HTML, text and file encoding that will allow me to generate in R a similar result to that of the Perl solution but I cannot find it. The header of the HTML page I'm trying to scrape says the chartset is utf-8 and I have set the encoding in the getURL call and in the write.table function to utf-8, but this alone isn't enough. The question How can I scrape the above web page using R and save the text as CSV in "well-formed" Japanese text rather than something that looks like line noise? Edit: I have added a further screenshot to show what happens when I omit the Encoding step. I get what look like Unicode codes, but not the graphical representation of the characters. So it may be some kind of locale-related issue, but in the exact same locale the Perl script does provide useful output. So this is still puzzling.

• Large invoice database structure and rendering

  - by user132624

  Our client has a MS SQL database that has 1 million customer invoice records in it. Using the database, our client wants its customers to be able to log into a frontend web site and then be able to view, modify and download their company’s invoices. Given the size of the database and the large number of customers who may log into the web site at any time, we are concerned about data base engine performance and web page invoice rendering performance. The 1 million invoice database is for just 90 days sales, so we will remove invoices over 90 days old from the database. Most of the invoices have multiple line items. We can easily convert our invoices into various data formats so for example it is easy for us to convert to and from SQL to XML with related schema and XSLT. Any data conversion would be done on another server so as not to burden the web interface server. We have tentatively decided to run the web site on a .NET Framework IIS web server using MS SQL on MS Azure. How would you suggest we structure our database for best performance? For example, should we put all the invoices of all customers located within the same 5 digit or 6 digit zip codes into the same table? Or could we set up a separate home directory for each customer on IIS and place each customer’s invoices in each customer’s home directory in XML format? And secondly what would you suggest would be the best method to render customer invoices on a web page and allow customers to modify for best performance? The ADO.net XML Data Set looks intriguing to us as a method, but we have never used it.

• Security in a private web service

  - by Oni

  I am developing a web site and a web service for a small on-line game. Technically, I'll be using Express (node.js) and MongoDB+Redis for the databases. This the structure I came up with: One Express server that will server as the Web Service. This will connect to the databases. One Express server that will provide the web site. It will connect to the Web Service to retrieve and push the information. iOS and Android application will be able to interact with the WebService. Taking into account: It is a small game. The information transferred is not critical. There will NOT be third party applications. At least for the moment. My concern is about which level of security I should use in each of the scenarios: Security of the user playing through web browser Security of the applications and the Web Server connecting to the WS. I have take a look at the different options and: OAuth and/or Https is too much for this scenario, isn't it? Will be a good option to hash the user and password with MD5(or similar) and some salt? I would like to get some directions and investigate by my own rather than getting a response like "you should you use this node.js module..." Thanks in advance,

• ASP.NET MVC WebService - Security for Industrial Android Clients

  - by Chris Nevill

  I'm trying to design a system that will allow a bunch of Android devices to securely log into an ASP.NET MVC REST Web service. At present neither side are implemented. However there is an ASP.NET MVC website which the web service will site along side. This is currently using forms authentication. The idea will be that the Android devices will download data from the web service and then be able to work offline storing data in their own local databases, where users will be able to make updates to that data, and then syncing updates back to the main server where possible. The web service will be using HTTPS to prevent calls being intercepted and reduce the risk of calls being intercepted. The system is an industrial system and will not be in used by the general Android population. Instead only authorized Android devices will be authorized by the Web Service to make calls. As such I was thinking of using the Android devices serial number as a username and then a generated long password which the device will be able to pick up - once the device has been authorized server side. The device will also have user logins - but these will not be to log into the web service - just the device itself - since the device and user must be able to work offline. So usernames and passwords will be downloaded and stored on the devices themselves. My question is... what form of security is best setup on the web service? Should it use forms Authentication? Should the username and password just be passed in with each GET/POST call or should it start a session as I have with the website? The Android side causes more confusion. There seems to be a number of options here Spring-Android, Volley, Retrofit, LoopJ, Robo Spice which seems to use the aforementioned Spring, Retrofit or Google HttpClient. I'm struggling to find a simple example which authenticates with a forms based authentication system. Is this because I'm going about this wrong? Is there another option that would better suite this?

• Project Showcase: SaaS Web Apps Hits a Home Run with New SCMS Database

  - by Webgui

  We love seeing projects from start to finish, and we’re happy to share the latest example with you. Who: SaaS Web Apps – they use Software as a Service to create web applications that look and feel like desktop applications. What: SaaS Web Apps needed to build a Sports Contract Management System (SCMS) for one of its customers, Premier Stinson Sports. Why: The SCMS database is used for collecting, analyzing and recording college coach and athletic directors’ employment and contract data. The Challenge: Premier Stinson Sports works with a number of partners, each with its own needs and unique requirements. For example, USA Today uses the system to provide cutting edge news analysis while The National Sports Law Institute of Marquette University Law School uses it to for the latest sports contract data and student analysis. In addition, the system needed to be secure due to the sensitivity of the data; it was essential that the user security and permissions be easily configurable. As always, performance was a key factor, especially with the intense reporting and analytical capabilities for this project. Because of this, most of the processing had to be done on a dedicated server but the project called for the richness and responsiveness of a desktop application. The Solution: To execute the project, SaaS Web Apps used APS.Net-based Visual WebGui from Gizmox, combined with SQL Server 2008 and SQL Reporting Services. This combination resulted in a quick deployment for SaaS Web Apps’ customers. The Result: The completed project gave each partner the scalability and availability of a web application with the performance and security of a desktop application. As an example, USA Today pulls data from this database to give readers the latest sports stats – Salary analysis of 2010 Football Bowl Subdivision Coaches. And here’s a screenshot of the database itself. Great work, SaaS Web Apps!

• How Does Domain Know Where Your Web Host Is Located [closed]

  - by icu222much

  Possible Duplicate: How Does Domain Know Where Your Web Host Is Located? I just purchased a domain name from RapidNames, and a hosting plan at JustHost. I was told to enter JustHost's name server (ns1.justhost.com) in my domain name's name server field and wait for 24 hours for the process to be complete. I do not understand how RapidNames can find my account on JustHost's server as I am sure I am not JustHost's only customer. I have read the article How DNS Works that John Conde has posted, but I still do not understand the issue. After reading several other articles, I am beginning to understand how it works, but I would still like someone to confirm if I am correct or not. From my understanding, linking your domain name to your web host is a two step process. First, you need to tell your domain name who your web host is. This is done by providing the two DNS server addresses. Secondly, you need to tell your web host which domain names you own by entering your domain names into the domain name manager. As a result, when someone queries your domain name, they will be forwarded to your web host. The web host will look in their database to match the domain name the account's owner, and then serve the appropriate website. I want to confirm if my understanding of how a domain knows where your web host is located is accurate?
