  • How do I upload a file from a Java servlet to a location on a web server within Tomcat/webapps

    - by Ankur
    How do I upload a file from a Java servlet to a location on a web server within Tomcat/webapps. I am using Commons upload. I have a location such as myserver:8080/myapp/mylocation where I want to put the files that are uploaded. I tried using getServletContext().getRealPath("/"); to find where I am and then appended that with mylocation but I get a nullpointer exception. I know I sound vague, it's because I am confused about the big picture, what are the generals steps I need to perform to make this work. Any code or links to code would be much appreciated.

  • Upgrading website from VS2005(2.0 Framework) to VS2008(2.0 Framework)

    - by Sravan
    We have a website that is created in VS2005 Recently we upgraded the website to VS2008 with 2.0 framework. While compiling the website Compilation errors are occuring i.e Licenses.licx file is not compiling, if it compile than it will reproduces an AppLicenses.dll. In the licensing.licx file containing one class and a namespace(i.e. OSADirectLicensing.OSADirectLicensedClass, OSADirectLicensing). The compilation error is as follows: Error 1 C:\Program Files\Sharp\Sharp Developer Tools\OSA SDK\Samples\DirectOSA\ExternalAuthority\licenses.licx: Could not transform licenses file into a binary resource. (1) : error LC0004 : Exception occurred creating type 'OSADirectLicensing.OSADirectLicensedClass, OSADirectLicensing, Version=1.0.4006.31768, Culture=neutral, PublicKeyToken=null System.ComponentModel.LicenseException: Invalid License at System.ComponentModel.LicenseManager.CreateWithContext(Type type, LicenseContext creationContext, Object[] args) at System.ComponentModel.LicenseManager.CreateWithContext(Type type, LicenseContext creationContext) at System.Tools.LicenseCompiler.GenerateLicenses(String fileContents, String targetPE, ITypeResolutionService resolver, DesigntimeLicenseContext ctx)' . Does VS2008 support licenses.licx or not? We should not remove this file from website. How can we solve this issue?

  • How do I modify this download function in Python?

    - by TIMEX
    Right now, it's iffy. Gzip, images, sometimes it doesn't work. How do I modify this download function so that it can work with anything? (Regardless of gzip or any header?) How do I automatically "Detect" if it's gzip? I don't want to always pass True/False, like I do right now. def download(source_url, g = False, correct_url = True): try: socket.setdefaulttimeout(10) agents = ['Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0)','Mozilla/4.0 (compatible; MSIE 7.0b; Windows NT 5.1)','Microsoft Internet Explorer/4.0b1 (Windows 95)','Opera/8.00 (Windows NT 5.1; U; en)'] ree = urllib2.Request(source_url) ree.add_header('User-Agent',random.choice(agents)) ree.add_header('Accept-encoding', 'gzip') opener = urllib2.build_opener() h = opener.open(ree).read() if g: compressedstream = StringIO(h) gzipper = gzip.GzipFile(fileobj=compressedstream) data = gzipper.read() return data else: return h except Exception, e: return ""

  • How can I pass a Visual Studio project's assembly version to another project for use in a post-build

    - by Coder7862396
    I have a solution with 2 projects: My Application 1.2.54 (C# WinForms) My Application Setup 1.0.0.0 (WiX Setup) I would like to add a post-build event to the WiX Setup project to run a batch file and pass it a command line parameter of My Application's assembly version number. The code may look something like this: CALL MyBatchFile.bat "$(fileVersion.ProductVersion($(var.My Application.TargetPath)))" But this results in the following error: Unhandled Exception:The expression """.My Application" cannot be evaluated. Method 'System.String.My Application' not found. C:\My Application\My Application Setup\My Application Setup.wixproj Error: The expression """.My Application" cannot be evaluated. Method 'System.String.My Application' not found. C:\My Application\My Application Setup\My Application Setup.wixproj I would like to be able to pass "1.2.54" to MyBatchFile.bat somehow.

  • Decorator for determining HTTP response from a view

    - by polera
    I want to create a decorator that will allow me to return a raw or "string" representation of a view if a GET parameter "raw" equals "1". The concept works, but I'm stuck on how to pass context to my renderer. Here's what I have so far: from django.shortcuts import render_to_response from django.http import HttpResponse from django.template.loader import render_to_string def raw_response(template): def wrap(view): def response(request,*args,**kwargs): if request.method == "GET": try: if request.GET['raw'] == "1": render = HttpResponse(render_to_string(template,{}),content_type="text/plain") return render except Exception: render = render_to_response(template,{}) return render return response return wrap Currently, the {} is there just as a place holder. Ultimately, I'd like to be able to pass a dict like this: @raw_response('my_template_name.html') def view_name(request): render({"x":42}) Any assistance is appreciated.

  • Authkit - deferring action to HTTP response to client application

    - by jon
    Form, Redirect and Forward all send an unauthenticated user to a Form on a login page specified within an Authkit middleware application. I'd like to allow a client application to request a service via XHR and then present a custom 'client side' form if a HTTP status code of 401 is returned, which would then post to Authkit for authentication until valid authentication/authorization occured. Specifically, 1) a jquery $.get request might request a resource. 2) if an Authkit cookie check confirmed previous authorization the content would be returned. 3) if not I would like Authkit to simply return the '401 response' (and not redirect to another page, or return a form template) where a client side exception handler would notify the user and present an authentication form. Can Authkit work like this?

  • Debugging stack data not assigned to a named variable

    - by gibbss
    Is there a way to view stack elements like un-assigned return values or exceptions that not assigned to a local variable? (e.g. throw new ...) For example, suppose I have code along the lines of: public String foo(InputStream in) throws IOException { NastyObj obj = null; try { obj = new NastyObj(in); return (obj.read()); } finally { if (obj != null) obj.close(); } } Is there any way to view the return or exception value without stepping to a higher level frame where it is assigned? This is particularly relevant with exceptions because you often have to step back up through a number of frames to find an actual handler. I usually use the Eclipse debugging environment, but any answer is appreciated. Also, if this cannot be done, can you explain why? (JVM, JPDA limitation?)

  • Programming style: should you return early if a guard condition is not satisfied?

    - by John Topley
    One thing I've sometimes wondered is which is the better style out of the two shown below (if any)? Is it better to return immediately if a guard condition hasn't been satisfied, or should you only do the other stuff if the guard condition is satisfied? For the sake of argument, please assume that the guard condition is a simple test that returns a boolean, such as checking to see if an element is in a collection, rather than something that might affect the control flow by throwing an exception. // Style 1 public SomeType aMethod() { SomeType result = null; if (!guardCondition()) { return result; } doStuffToResult(result); doMoreStuffToResult(result); return result; } // Style 2 public SomeType aMethod() { SomeType result = null; if (guardCondition()) { doStuffToResult(result); doMoreStuffToResult(result); } return result; }

  • Cant open Nerd Dinner 1.0 VS 2008 SP1 MVC 2

    - by josephj1989
    I was trying to download some ASP.NET MVC Sample application to learn MVC. I tried Music Store and TownHall but they wont open in my VS2008.So I tried the common Nerddinner 1.0 but it gives error "The project Type is not supported by this installation" . I tried the 3rd Method suggested in the following post http://stackoverflow.com/questions/1002907/cant-open-nerddinner-project-in-vs2008 This is about changing the project type GUIDS.Now the project loads but when I run it throws an exception <add assembly="System.Web.Mvc, Version=1.0.0.0, Culture=neutral,PublicKeyToken=31BF3856AD364E35" /> I presume this is happening because the Nerddinner 1.0 is for MVC 1.0 and I have MVC 2.0 installed. How do I proceed now. I have spent a lot of time trying to get an MVC application working on my PC. I am happy if I can get any properly architected , MVC application of medium to high complexity to work on my PC. thanks

  • Regex to allow all php files except one

    - by Tim
    Hi all, I have this regex that allow all php files : ^.*\.([Pp][Hh][Pp]) how can I exclude a specific file, for example test.php ? Thanks for your answer, Best regards [edit] I omit to say that it is a reg from a htaccess file, the /i doesn't seems to work, and the ? neither. [Edit2] the purpose is to grant access to authenticated users, except for one file that has to be allowed for everyone. So I've done : <Files ~ "^.*\.([Pp][Hh][Pp])$"> AuthUserFile /directory/.htpasswd AuthGroupFile /dev/null AuthName "Please log in ..." AuthType Basic require valid-user </Files> So, all php files require valid user. I would like to add an exception for a specific file, says test.php

  • Timespan not accepting day in MVC3

    I have a MVC3 application in which i want to set a timespan to for example 2 days and 5 hours. when i enter 02:05:00:00 it gives me the following exception: System.OverflowException: SqlDbType.Time overflow. Value '2.05:00:00' is out of range. Must be between 00:00:00.0000000 and 23:59:59.9999999. When i enter 05:00:00 it correctly saves 5 hours into the database. according to MSDN timespan has a property for days. How do i correctly set the days? Model: public class ProductionTimeVM { [Required] public TimeSpan DefaultTime { get; set; } } In my view i just use: @Html.TextBoxFor(x => x.DefaultTime) For my controller: public ActionResult SaveProductionTime(ProductionTimeVM vm) { ProductionTime productionTime = new ProductionTime(); productionTime.Default = vm.DefaultTime; //some more code } Any idea's?

  • When to override OnError?

    - by Ek0nomik
    I'm looking into re-working and simplifying our error handling in an application I support. We currently have all of our pages inheriting from a base class we created, which in turn obviously inherits from System.Web.UI.Page. Within this base class, the OnError method is currently being overridden, and in turn calling MyBase.OnError, and then calling one of our custom logging methods. I don't see any benefit of overriding the OnError method, and I think it would be better to let the Application_Error method in the Global.asax take care of the unhandled exception (logging it) and then the customErrors section in the config would trigger a process to redirect the user. Looking online it looks like people override this method quite frequently, but I don't see a need to and this article from MSDN makes me think the same.

  • .net, using PowerShell class to invoke a "[namespace.class]::method" style command

    Hello, I created a powershell object via .net to invoke commands. When I invoke normal commands like 'Get-Process' I had no problems: ps.AddCommand("Get-Process").AddParameter(...).Invoke() but I'm not able to invoke a .net method with the syntax "[namespace.class]::method", just to make an example to invoke [System.IO.File]::Exists("c:\boo.txt"). I tried with ps.AddCommand("[System.IO.File]::Exists(\"c:\boo.txt\")").Invoke() ps.AddCommand("[System.IO.File]::Exists").AddArgument("c:\boo.txt\").Invoke() and some others. It always throws an exception which says that the command specified is not recognized. There is a way to invoke that type of command? Thanks

After i've tested and happy everythings working I move it from localhost to IIS. Now when I do this I get an exception in the POST handler code. How on earth can I debug this code line by line? I managed to do this awhile ago, I thought it was by attaching to process but I can't work it out. I can emulate GET just by typing address in browser, post im not sure about.

As a possible solution, is it enough to: public class Key { private char[] key; // ... protected void finalize() throws Throwable { try { for(int k = 0; k < key.length; k++) { key[k] = '\0'; } } catch (Exception e) { //... } finally { super.finalize(); } } // ... }

  • Automapping to EntityKeys in Entity Framework

    - by CodeGrue
    Does anyone have a technique to automap (using Automapper) references to child entities. So say I have a ViewModel: class AddressModel { int Id; string Street; StateModel State; } class StateModel { int Id; string Name; } And I pass this into a repository to map to equivalent entities in Entity Framework. When Automapping, I want it to automap AddressModel.State.ID to the EntityKey of AddressEntity.StateReference. So hand crafted code would look like this: addressEntity.Id = AddressModel.Id; addressEntity.Street = AddressModel.Street addressEntity.StateReference.EntityKey = new EntityKey("MyDB.States", "Id", AddressModel.State.Id); Obviously, when automapper tries to assign an Address.State.Id to the equivalent in EF, an exception is thrown.
