I'm developing a webapp using tiles and spring mvc. With the use of xsd and dtd validation on the definition of tiles and bean declaration of spring mvc, each time the web app is start/restart, then requests are sent to external server for xsd and dtd files. I notice that because my webapp failed to start casually due to failed request to external server (!!!).
I wonder if there is a way to tell my app to stop doing that? Like place a cached version of these files somewhere, or tell the Xml Processor to not valid these xml files at run time?
I'm facing a similar problem (but with xsd files.) After a little research, it appears that generally, foo-1.0.jar will contain foo-schema-1.0.xsd and therefore when foo goes to validate its foo-config.xml, it doesn't need to ask the Internet for the xsd.
The problem comes when you upgrade to foo-1.1.jar (which includes the new foo-schema-1.1.xsd) without changing your foo-config.xml to reference the new version of the schema. foo-1.1.jar doesn't contain foo-schema-1.0.xsd, so the parser looks for it on the Internet. If the site is trying to look at is down, you have problems.
So check your xml files to make sure they're referencing the version of the xsd/dtd appropriate for the jar version which is validating them.

All,
Sorry in advance - I'm a total novice when it comes to ASP.net.
I'm working on a project that's fairly simple. I have single HTML page that collects input from the user. When the input is complete - the html page uses AJAX to post the data to a web service. That service receives the data, does some processing on it, then sends back a response.
The "client" part of this app is pure HTML/Javascript (not ASP.net), and is complete and works perfectly.
The "service" part of this app (MyHandler.ashx) is built using ASP.net. Technically - what it does is receive data from the AJAX post. It then uses Microsoft.Office.Interop.Excel to open an Excel spreadsheet, pass the users' inputs into that spreadsheet, then retrieve several calculated values from the spreadsheet, and returns those values in the response to the AJAX post.
Using Visual Studio VS I've got this whole process running locally on my PC.
When I "publish" the project - VS creates a ton of files. I sent those files to the team that manages the server; they deployed them, and voilà - it works. (The necessary Office interop libraries are installed on the server).
So - my question - as I make a few modest changes (e.g., validation, error handling) to the handler - MyHandler.ashx - which of those published files actually change? If i want to reploy - do I simply need to resend an updated version of MyHandler.ashx? Or, do simple coding changes to that file require changes to the DLL?
I guess my question is, generally - what's in the DLL? (E.g., is it a compiled version of MyHandler.ashx?)
More specifically - publishing my project creates the following files that I don't really understand:
Web.config
Global.asax (in my project, there's not much in here)
bin/MyProject.dll
So, if I make changes to MyHandler.ashx - can I simply reploy THAT file? Or, do I need to "publish", then "redeploy" thd dll? (By changes - I mean simple code changes, not decisions to include/exclude other external dependencies).
Sorry - this question must seem like nonsense to knowledgeable ASP.net developers. But, with other technologies I've used, things were clear:
If you're developing a Flash project, you write source code in .FLA files, then compile, then deploy the resulting .SWF files.
If you're developing an HTML/JavaScript/PHP project, you write those files, then deploy those same files
I'd trying to get a better understanding of what's what with ASP.net.
Thanks again.
The DLL contains the compiled code behind the ASHX file. The ASHX is just a service definition for an HTTP handler. When you make changes to the service (e.g. the code), simply issue another Publish like you did before and send the entire package.
But in short, when you change the code, the DLL is what's changing.
Is there some sort of configuration settings in FlashBuilder 4.5 where you can easily switch between webservice urls? Right now I have to delete and recreate the web service every time I switch from local to production and vice versa.
The need/requirement is this – Since I work in a startup, we keep changing servers, and their IP addresses. And being a service oriented application – I need to be able to edit the webservice endpoints in my Flex application in a easy manner every time this happens.
My Solution for this -
Assumption is that my webservice endpoint looks like this -
http:////ListAllServices/
1) Create a file config.xml in a folder named “settings” that sits in the root folder of your Flex application – outside the “src” folder. And the config.xml will be a simple xml file of the following format -
localhostTestFlexApp
At the end of this exercise the directory structure of your flex source code will look like this -
flex_src(root of the source code)
-com(some source folder)
–testapp
—view
—
-images
-settings
–config.xml
-appName.mxml
2) Now in your application code, setup a HTTPService object either in mxml or action script. Set the url of that object to this value- “settings/config.xml” – And the above xml fiel containing the current settings will be loaded into memory .
Now you can store these values in a singleton object and construct your Webservice call at runtime.
And whenever you want to move this to a new server in production, edit the tag of your config.xml and you should be good to go.
And this can be automated as well via the EnvGen ant task.
This is not the best way but yes it is very helpful while switching among servers.
Alrighty... The way I was doing it before in fact worked. The problem was browser caching.
For the benefit of others I modified the subsclass for the generated service and replace the wsdl variable with whatever endpoint I need.
I want to make a "properties style web form" that shows the application version for various .NET applications.
If I know the URL e.g. /someapp/default.aspx is it possible via reflection to execute that page and figure out the assembly version?
It's quite easy to find the executing assembly version, but without modifying the other application, is it possible?
Both the property page and the other application is running on the same server and in the same application pool.
Update: I've had some luck with
var url = "~/SomeApp/default.aspx";
var appType = System.Web.Compilation.BuildManager.GetCompiledType(url);
But navigating appType to find the assembly file version is not the same everytime.
Without modifying the web application to expose the version number through some URL-based retrieval (a simple page GET being the easy, obvious one), you're going to need to find a way to figure out where the DLL for the web application is from the URL.
If you can know the DLL's location, either by some convention (e.g. /appX/ is always at D:\Sites\appX\bin\appX.dll) or some configuration (you manually enter where each URL base's DLL is in a database), then you can retrieve that DLL's assembly version using the following code:
Assembly assembly = Assembly.LoadFrom("MyAssembly.dll");
Version ver = assembly.GetName().Version;
Code taken from this question.
Edit:
I've had a little look around, and there are some APIs to inspect the IIS configuration, so this is certainly a route to explore if you're trying to get from the URL to the assembly location. This question has an example of getting the physical path from the application/site name, for example. Microsoft.Web.Administration is the assembly to explore.
The ASP.NET engine streams nothing but HTML, javascript, etc.. to the client. There is nothing left of the assembly that gets passed in the response that can show what version of .net/asp.net that the application is running unless the developer on the server side adds it.
That said, you can gather some information from a utility at http://uptime.netcraft.com/up/graph that will give you some server information. Not down to the assembly version, but this is as close as I believe you are going to get.
You may implement custom HttpModule, put it to the bin folder of each application that you wish to monitor and append register this module in web.config files. In this module for example you should handle request, retrieve all required information and put it to response cookie.
I am having an issue when attempting to override the DisplayNameAttribute in ASP.NET MVC to provide a localized string. The code itself is straightforward and similar to that in another Stackoverflow post link text
The code works for global resources but not so well for local resources. I have a registration screen and used the Visual Studio "Generate Local Resource" command to create my local resource file. The generated file is named Registration.aspx.resx and the App_LocalResources folder is created relative to the actual Registration.aspx page - as one would expect.
However, when I attempt to get the localized string using:
ResourceManager.GetString(resourceKey)
I receive the following error message.
Could not find any resources
appropriate for the specified culture
or the neutral culture. Make sure
"FullAssemblyName.Views.Account.App_LocalResources.Registration_aspx.resources"
was correctly embedded or linked into
assembly "FullAssemblyName" at compile
time, or that all the satellite
assemblies required are loadable and
fully signed.
Using reflector, I can see that the file is actually Registration.aspx.resources and not Registration_aspx.resources - the underscore/period being the subtle difference
FullAssemblyName.Views.Account.App_LocalResources.Registration.aspx.resources
I have toyed with the code quite a bit but no matter what I do, the file being requested is always different than that copiled in the assembly. For instance, if i rename Registration_aspx (in the generated Registration.aspx.designer.cs class i get the same error but this time the path is "...App_LocalResources.Registrationaspx.resources"
Has anyone run into this? Is there any way I can ensure that the resource found in my assembly has this underscore?!?!?
Thank you in advance!
Try Michael K. Campbell solution link text. It worked fine form me in localizing my project.
I've a simple, if not primitive, C++/CLI .NET 2.0 class library. It is used in order to wrap some C++ legacy code for the Web Service. The following facts appear to be true:
Primitive C# test program calls class library and it works.
If class library does not refer to any modules of our code base, it works as well as part of the web service. That is, I load the web service and invoke the methods and receive proper response.
The same moment I replace the copied and pasted code by the calls from our code base libraries, the Web Service stops to load. I get System.IO.FileNotFoundException message.
The problem: I cannot find any place where the file name that couldn't be found is written.
I googled it and gave some permissions to some ASP.NET user on my computer. I copied all the DLLs of our libraries into the same directory where web service is installed. I searched in IIS logs, event logs, etc - no where could I find the name of the module that prevents the web service from coming up.
Any help on the matter would be greatly appreciated.
Boris
Make sure all the dependent DLLs are in the path (Path meaning not the directory where your assembly is, because ASP.net copies your assembly away into a temporary folder, but rather a directory that's included in the System path environment variable).
What calls are you replacing? Could it be the original code gracefully handles missing files (which may not even be important) and yours does not?
Add same rights to the iusr-account that you did to the asp.net-account.
