• NetBeans Web-Services Client Project - repeated WSDL parsing

  - by RedGrittyBrick

  I created a new project thus ... File, New Project... Java, Java Application. Right-click project icon in "Projects" tree-view panel. Choose New, Web Service Client... Specify WSDL file e.g. ( ) Project (*) Local file D:\temp\Foo\Bar.wsdl ( ) WSDL URL [Set Proxy...] client-style JAX-WS [ ] Generate Dispatch code It parsed the WSDL and generated lots of java files. I created a main class and used Netbeans to insert a WS client call Now whenever I run my code (Desktop app), it again parses the WSDL (which doesn't ever change) and regenerates about 78 java files and compiles them. How do I stop Netbeans performing this uneccessary and time-consuming action?

• Why GWT? Advantages and Trade-Offs of Using This RIA Framework

  - by prometheus

  I'm new to stackoverflow and have been reading through a bunch of the "highest voted" questions for GWT. Several of these questions talk about the pitfalls or problems with GWT. In the articles: Which Javascript framework (jQuery vs Dojo vs … )? and Biggest GWT Pitfalls?, some posters seem to suggest that GWT is not lightweight enough or that there are better alternatives that may be used. Do most of you feel that there are problems with GWT that have not been fixed with GWT 2.0 -- which would make you inclined to suggest using a simpler framework for a new project? To some extent, shouldn't GWT be somewhat future-proof (since you don't have to worry about it changing drastically from release to release and since it is backed by Google)? I realize that the answer to this question depends greatly upon what you want to do or what you wish to make. I am looking at this from the perspective of starting a new web application that will eventually be used by millions of users.

• Managing multiple .NET languages in a web application

  - by tomfanning

  I am part of a development team building a new ASP.NET 3.5 web application. Two of us are C# coders, and the other is a VB.NET coder. I know that we can mix languages on a per-project basis, and one can build classes in one language that inherit from classes written in the other language in a different project (which we are already doing), but I can see us getting into a situation where we might well end up with cyclic dependencies between our various project DLLs. Other than simply having a high number of projects (more seperation of concerns into more libraries), how have you managed this situation on your own projects? Note - I believe this question to be different enough from the only similar match I could find (this one) on the basis that we are not wanting to use different languages in order to take advantage of their specific features per se, but rather to make use of what developer resource is available to us (i.e. one dev just happens to be VB.NET only).

• Dynamic page with JSF

  - by Milan

  Hello everybody! I need to make dynamic web-page/form in JSF. Dynamic: In runtime I get the number of input fields Ill have together with buttons. I'll try to demonstrate you what I need to make. inputField1 inputField2 inputField3 BUTTON1 inputField4 inputField5 BUTTON2 inputField6 inputFiled7 inputField8 inputField9 BUTTON3 I hope you understand me what I want to make. So I when I click on some of the buttons I have to collect the data from the input fields and do something with the data. If I click BUTTON1 I collect data from inputField1 inputField2 inputField3 BUTTON2 inputField4 inputField5, etc. Probably I should create the input fields programmatically and group them in forms. Any idea how to do it? Any idea?

• Rest Web Service with App Engine and Webapp

  - by fceruti

  I want to build a REST web service on app engine. Currently i have this: from google.appengine.ext import webapp from google.appengine.ext.webapp import util class UsersHandler(webapp.RequestHandler): def get(self, name): self.response.out.write('Hello '+ name+'!') def main(): util.run_wsgi_app(application) #Map url like /rest/users/johnsmith application = webapp.WSGIApplication([(r'/rest/users/(.*)',UsersHandler)] debug=True) if __name__ == '__main__': main() And i would like to retreive for example all my users when the path /rest/users is accessed. I Imagine I can do this by building another handler, but I want to know if is possible to do it inside of this handler.

• How do I resolve the config error which states a machine to application error

  - by waterfalrain

  I imported a website made in visual studio express 2008 to visual studio express 2010. When I run the home page I get the following error: "It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS." When I looked up the meaning of this on Google I read their needed to be a change to the configuration of the virtual directory. Another suggestion was to change the web config files . T Were these suggestions correct? If so how do I emplement them so that I can view these website pages on my local machine.

• Recommendation needed for text content, should I use text files or database?

  - by Jörgen

  I'm doing a web application in asp.net mvc. Now I'm at the point where I do alot of text info such as help texts, eula, privacy policy etc. I realized that I'm not sure what would the best way to store these texts. 1.

In my sql database If use option 3 how would I then design the database e.g. eula = table x, privacypolicy=table y? I guess I just need some directions of what't the pros and cons with the options above.

• Modifying generator.yml views in Symfony

  - by Alex Ciminian

  Hey! I'm currently working on a web app written in Symfony. I'm supposed to add an "export to CSV" feature in the backend/administration part of the app for some modules. In the list view, there should be an "Export" button which should provide the user with a csv file of the elements that are displayed (considering filtering criteria). I've created a method in the actions class of the module that takes a comma separated list of ids and generates the CSV, but I'm not really sure how to add the link to it in the view. The problem is that the view doesn't exist anywhere, it's generated on the fly from the data in the generator.yml configuration file. I've posted the relevant part of the file below. list: display: [=name, indemn, _status, _participants, _approved_, created_at] title: Lista actiuni object_actions: _edit: ~ _delete: ~ filters: [name, county_id, _status_filter, activity_id] fields: name: name: Nume Actiune indemn: name: Îndemn la actiune description: name: Descriere approved_: name: Operatiune created_at: name: Creata la status: name: Status Actiune I'm new to Symfony, so any help would be appreciated :). Thanks, Alex

• Amazon SQS invalid binary character in message body

  - by letronje

  I have a web app that sends messages to an Amazon SQS Queue. Amazon sqs lib throws a 'AmazonSQSException' since the message contained invalid binary character. The message is the referrer obtained from an incoming http request. This is what it looks like: http://ads.vrx.adbrite.com/adserver/display_iab_ads.php?sid=1220459&title_color=0000FF&text_color=000000&background_color=FFFFFF&border_color=CCCCCC&url_color=008000&newwin=0&zs=3330305f323530&width=300&height=250&url=http%3A%2F%2Funblockorkutproxy.com%2Fsearch.php%2FOi8vZG93%2FbmxvYWRz%2FLnppZGR1%2FLmNvbS9k%2Fb3dubG9h%2FZGZpbGUv%2FNTY5MTQ3%2FNi9NeUN1%2FdGVHaXJs%2FZnJpZW5k%2FWmFoaXJh%2FLndtdi5o%2FdG1s%2Fb0%2F^Fô}úÃ<99ë)j Looks like the characters in bold are the invalid characters. Is there an easy way to filter out characters characters that are not accepted by amazon ? Here are the characters allowed by amazon in message body. I am not sure what regex i should use to replace invalid characters by ''

• Creating a System.Web.UI.Page programatically in IHTTPHandler

  - by ObiWanKenobi

  I am trying to use the ASP.NET (3.5) "Routing Module" functionality to create custom pages based on the contents of the URL. Various articles, such as this one: http://blogs.msdn.com/mikeormond/archive/2008/05/14/using-asp-net-routing-independent-of-mvc.aspx explain how to use ASP.NET Routing to branch to existing pages on the web server. What I would like to do is create the page on-the-fly using code. My first attempt looks like this: public class SimpleRouteHandler : IRouteHandler { public IHttpHandler GetHttpHandler(RequestContext requestContext) { string pageName = requestContext.RouteData.GetRequiredString("PageName"); Page myPage = new Page(); myPage.Response.Write("hello " + pageName); return myPage; } } But this throws an HTTPException saying "Response is not available in this context." at the Response.Write statement. Any ideas on how to proceed? UPDATE: In the end, I went with an approach based on IHttpModule, which turned out to be rather easy.

• Default login popup for web sites

  - by John Quest

  Hi. I am trying to build a web site with ASP.NET MVC, I'm new to this. My question is: how can I display the default login dialog? I am not referring to a custom dialog, like the jQuery Dialog, there is a default pop-up for credentials, which looks different depending on browser, same as with javascript alert(), but I don't know how to display it. To know what I mean, go to http://fit.c2.com/wiki.cgi?WelcomeVisitors, there is a Login button at the bottom of the page, when you click it a pop-up appears. That is what I want to display. Any ideas?

• close fails on database connections (managed connection cleanup fails) in websphere 7 but not in web

  - by mete

  I have a simple method (used in a web application through servlets) that gets a connection from a JNDI name and issues a select statement (get connection, issue select, return result, close the connection etc. in finally). Due to other methods in the application the connection is set as autocommit=false. This method works normally in websphere 6.1 as well as in glassfish and weblogic. However, in websphere 7, it receives cleanup failed error when I close the connection because, it says, the connection is still in a transaction. Because I was not updating anything I did not commit or rollback the connection in this method (which can be wrong). If I add commit before closing the connection, it works. My question is why it works in websphere 6.1 (and other containers) and why not in websphere 7 ? What can be the cause of this difference ?

• Eclipse 3.5 Missing New Web Application option after installing Google App Engine plugin

  - by stevebot

  Hey all, I just used Eclipse 3.5 to install the Google App Engine plug in. The plug in is showed as installed in the update manager. However, I am not seeing the option to "New Web Application Project" (http://code.google.com/appengine/docs/java/tools/eclipse.html). I also don't see anything Google related when I type Google into the search bar under Windows Preferences. There were no errors at the time of installation, and I was asked if I wanted to restart Eclipse, clicked yes, and it restarted accordingly. Am I missing something?

• Can I autoregister my clients/servers in local DNS?

  - by Christian Wattengård

  Right now I have a W2k12 server at home that I run as a domain controller. This has the extra benefit of registering every "subordinate" computers name in it's DNS so that I don't have to go around remembering IP's all the time. (And it let's me easily run dhcp also on my servers). I need to rework my home network for several odd reasons, and in this new scenario there is no place for a big honking W2k12 server box. I have a RasPI, and I have other smallish linux boxen I can use. (In a worst case scenario I'll use my NUC, but then I'll be forced to use my home cinema's UPnP-client for media... The HORROR!!) Is it possible to set up a DNS-server-"appliance" that somehow autoregisters it's own hostname.. Scenario: Router (N66u) on 172.20.20.1. Runs DHCP on 172.20.20.100-200 range. Server [verdant] of a *nix flavor on 172.20.20.2 Laptop [speedy] of W8 flavor on DHCP assigned Laptop [canary] of W8 flavor on DHCP assigned Desktop [lianyu] of Ubunto flavor on DHCP assigned What I would like is that all of the above servers (except possibly the router) would be available on verdant.starling.lan and canary.starling.lan and so on. This is how it works right now (except the Ubuntu box... I haven't cracked that one yet) because Windows just does this for you.. I would also be able to do this without any manual labor on the server. When I tell my box it's name is smoak it should "immediately" be available as smoak.starling.lan without any extra configuration on my part. How can I do this in a Linux (Ubuntu) environment? (Bonus comment upvote for naming the naming scheme :P )

• Validation Rules in Webtesting using VS2010

  - by Lexipain

  I'm creating a simple webtest (Recorded Web performance test) that makes sure that a correct error message is displayed if i try to login with a username that does not exist. However, there are two types of error messages that handle incorrect login info. One is for all the usernames that do not exist and therefore are not allowed, and the other is for usernames that start with the letter 'Q' (which is not allowed for a few reasons). Now what i want to do is use the 'Find Text' validation rule and the test should pass if ONE of the 'Find Text' parameters is found, and in that case i want the second 'Find Text' rule to be ignored so it doesn't fail the test. In other words the test should always pass if one of the 'Find Test' rules is found. How can i achieve that? Is there some if,else statement that i can use for this?

• Graphics.RotateTransform works on localhost, but not on remote server

  - by harriyott

  It works on my machine... I'm combining two map pins into a single image. I load an empty pin image and write a number on top of it. I then combine two of these, having rotated one 15 degrees and the other -15 degrees. It looks fine running through my localhost web server: I upload this to my shared server, and I get this instead: I load the image thus: var g = Graphics.FromImage(image); The line to rotate the image is: g.RotateTransform(angle); I'm sure this must be a setting somewhere, but I've had no luck finding it.

• JavaScript multithreading

  - by Krzysztof Hasinski

  I'm working on comparison for several different methods of implementing (real or fake) multithreading in JavaScript. As far as I know only webworkers and Google Gears WorkerPool can give you real threads (ie. spread across multiple processors with real parallel execution). I've found the following methods: switch between tasks using yield() use setInterval() (or other non-blocking function) with threads waiting one for another use Google Gears WorkerPool threads (with plugin) use html5 web workers I read related questions and found several variations of the above methods, but most of those questions are old, so there might be a few new ideas. I'm wondering - how else can you achieve multithreading in JavaScript? Any other important methods? UPDATE: As pointed out in comments what I really meant was concurrency. UPDATE 2: I found information that Silverlight + JScript supports multithreading, but I'm unable to verify this. UPDATE 3: Google deprecated Gears: http://code.google.com/apis/gears/api_workerpool.html

• Deploying only changed part of a website with git to ftp (svn2web for git)

  - by Elazar Leibovich

  I'm having a website with many big images file. The source (as well as the images) is maintained with git. I wish to deploy that via ftp to a bluehost-like cheap server. I do not wish to deploy all the website each time (so that I won't have to upload too many unchanged files over and over), but to do roughly the following: In a git repository, mark the last deployed revision with a tag "deployed". When I say "deploy revision X", find out which files has changed between revision X and revision tagged as deploy, and upload just them. It is similar in spirit to svn2web. But I want that for DVCS. Mercurial alternative will be considered. It's a pretty simple script to write, but I'd rather not to reinvent the wheel if there's some similar script on the web. Capistrano and fab seems to know only how to push the whole revision, in their SCM integration. So I don't think I can currently use them.

• Is it possible to get code coverage data for a GWT web app running tests from the web browser?

  - by jeff

  I am not sure if this is possible but I would like some way to get code coverage information for tests that are written in Quick Test for our GWT based web app. It does not seem like there is any solution because the Quick Test Pro tests are testing against the GWT compiled app and not the original java code in which the app was written. I suppose I could get coverage data on the javascript that the GWT compiler creates, but there would be no way for me (that I know of) to map this information back to the original java code. Is there some way to do this?

• Should I obscure primary key values?

  - by Scott

  I'm building a web application where the front end is a highly-specialized search engine. Searching is handled at the main URL, and the user is passed off to a sub-directory when they click on a search result for a more detailed display. This hand-off is being done as a GET request with the primary key being passed in the query string. I seem to recall reading somewhere that exposing primary keys to the user was not a good idea, so I decided to implement reversible encryption. I'm starting to wonder if I'm just being paranoid. The reversible encryption (base64) is probably easily broken by anybody who cares to try, makes the URLs very ugly, and also longer than they otherwise would be. Should I just drop the encryption and send my primary keys in the clear?
