  • How do I configure Jetty (via jettyrunner) so that it names a character set in the Content-Type response header?

    - by Pointy
    I use Jetty (via the oh-so-handy Jetty Runner) for day-to-day web application testing. One thing I've recently stumbled on is the fact that I don't get a character set called out in the "Content-Type" response header all the time. I do get it in response to my application's XMLHttpRequest transactions, but not for plain old pages loaded by <a> links or whatever. I've read a little bit about how to set up a Jetty config file, but I've never been able to completely understand that; all servlet containers are complicated, and while Jetty is pretty simple it's just weird enough that I don't grok the overall idea. Thus, all I do to launch my app is to run the Jetty Runner .jar file with a couple of simple arguments to set up the port number and logfile path, and then I just give it the .war file to run. It works great — except for the missing character set :-) Anybody have a quick sample config file that might fix this? edit — oh if it matters, I'm running Jetty 7.0.0 RC3; I've also tried with a slightly newer version (still 7.something) with exactly the same issue. All my testing is on Ubuntu.

  • Needs management tool for .java files

    - by Chris Okyen
    When I open the src file in the project folder in Package Explorer in Eclipse, it says the following: Error retrieving content description for resource '/GuiAdd/src/GuiAdd.Java.' Now, the directories of the source projects shown in Eclipse Package explorer doesn't always have the source file to link to, causing this message. I need a way to sync the folders in the correct directory without overwriting the newest ones. Some source files I project files of the root which the Package explorer links to may be the correct versions but other source files in the root may not have the latest source or any source. I am not using svn/git or other depository programs.

  • Capture virtual machine traffic in Fiddler

    - by HtS
    I'm running Ubuntu in a virtual machine (host machine is Windows 7). Is it possible to use Fiddler in the host machine to capture the traffic from the virtual machine? Seeing as the virtual machine's network must be passing through the host computers NIC, can Fiddler capture the packets? (I don't know of any free alternative to Fiddler for Linux, except Tamper Data, but I need a bit more control). Thanks.

  • IPTables configuration help

    - by Sam
    I'm after some help with setting up IPTables. Mostly the configuration is working, but regardless of what I try I cannot allow localhost to access the local Apache only (i.e. localhost to access localhost:80 only). Here is my script: !/bin/bash Allow root to access external web and ftp iptables -t filter -A OUTPUT -p tcp --dport 21 --match owner --uid-owner 0 -j ACCEPT iptables -t filter -A OUTPUT -p tcp --dport 80 --match owner --uid-owner 0 -j ACCEPT Allow DNS queries iptables -A OUTPUT -p udp --dport 53 -j ACCEPT iptables -A OUTPUT -p tcp --dport 53 -j ACCEPT Allow in and outbound SSH to/from any server iptables -A INPUT -p tcp -s 0/0 --dport 22 -j ACCEPT iptables -A OUTPUT -p tcp -d 0/0 --sport 22 -j ACCEPT Accept ICMP requests iptables -A INPUT -p icmp -s 0/0 -j ACCEPT iptables -A OUTPUT -p icmp -d 0/0 -j ACCEPT Accept connections from any local machines but disallow localhost access to networked machines iptables -A INPUT -s 10.0.1.0/24 -j ACCEPT iptables -A OUTPUT -d 10.0.1.0/24 -j DROP Drop ALL other traffic iptables -A OUTPUT -p tcp -d 0/0 -j DROP iptables -A OUTPUT -p udp -d 0/0 -j DROP Now I have tried many permutations and I'm obviously missing everything. I place them above the in/out bound SSH to/from, so it's not the precedence order. If someone could give me the heads up on allowing only the local machine to access the local web server, that'd be great. Cheers guys.

  • Podlogger Half Baked Code, but yours for free.

    Some time ago I started building a demo application that would have been posted on www.asp.net. It is a Podcast Publishing application and completing basic functionality we decided that it was a bit too complex for the intended introductory material. Though not finished (Meaning NOT FINISHED, INCOMPLETE, IMPERFECT, ETC) I thought Id share it in case anyone finds it useful. Some of the stuff that is in there : Basic Post Publication with Rich Editor File Upload Comments Submission...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • reading k&r(c book) and confusing 1st chapter code [closed]

    - by DarkEnergy
    #include <stdio.h> /* copy input to output; 2nd version*/ main() { int c; while ((c = getchar()) != EOF) putchar(c); } this is very confusing... since you never escape the while loop. I've learned that EOF is -1. i type -1 but it just reprints it. It's a never ending loop. Over time did the library get changed and differs from what the book intended it to be? when i say library i mean the putchar()/getchar() that's in the library... sorry.

  • How can I remove the IM status entries from the messaging indicator?

    - by spoonfood
    On 11.10: I know how to remove the email & u1 entries using blacklist/remove from /usr/share/blablabla_youknowwhere but I see no entries or solutions on how to remove only the status entries, as I dont use any IMs, only mail & u1. I suspect its hardcoded, please let me be wrong. but if it is so, maybe someone enlightened got a diff/patch, although I fear it will lead to dependency hell (compiling wise)

  • A better way to organize your Silverlight Code Snippets.

    - by mbcrump
    I hate re-writing code. I also hate it when I find a great code snippet on the web and forget to bookmark it or it gets lost in my endless sea of bookmarks. So what do you do to get around this? This is the question that I was asking myself at the end of 2010. How can I get my Silverlight code organized? My requirements for a snippet manager were: Needs to be FREE. An easy way to view XAML/C# code behind together in one “view”. I wanted the ability to store the code snippets in cloud in case my HDD dies. Searchable Keywords to quickly find code snippets. I started looking for a snippet manager that would allow me to do just that and finally found Snippet Manager. Before going any further, I think that one of the most important things to note here is that this software supports 37 languages. It’s not just for Silverlight developers nor C# only guys. The software supports Java, SQL and even COBOL.   Below is a screenshot of the Snippet Manager that shows my Silverlight code snippet. You will notice that I have highlighted two sections. The top part is my XAML and the bottom is my C# code behind. I’ve included a sample below of my code snippets so that you can get an idea of how I organized it. Another thing that’s great about this software is that it supports plain text. I added some connection strings in the TEXT section below.  Once you have finished adding your code snippets, you can store them in the cloud. I created a FTP directory called “snippets” on my FTP Server and hit the upload button once I am finished adding my new codes snippets. This will allow me to use the code snippets on another computer with this application on my USB Key. See screenshots below: Enter your FTP credentials below: Hit the Uploads button on the Toolbar: Login in to your FTP Server and verify the following files are now on the FTP Server: Another great feature of the Snippet Manager is that you can also integrate this into VS2010 by clicking Tools –> External Tools: And setting up your External Screen to point to the Executable: You can now launch it by going to Tools –> Snippet Manager. If you want you could also a shortcut to launch the program with HotKeys. As you can see, this is a nice little program that includes everything needed to organize your code snippets very clean. I didn’t go over every feature but this is something that you might want to download and give it a shot.  Subscribe to my feed CodeProject

  • What Do You Think About This Smelly Test?

    - by panamack
    I caught a whiff of a smell eminating from one of my tests, in a scenario akin to the following: [TestFixture] public void CarPresenterTests{ [Test] public void Throws_If_Cars_Wheels_Collection_Is_Null(){ IEnumerable<Wheels> wheels = null; var car = new Car(wheels); Assert.That( ()=>new CarPresenter(car), Throws.InstanceOf<ArgumentException>() .With.Message.EqualTo("Can't create if cars wheels is null)); } } public class CarPresenter{ public CarPresenter(Car car) { if(car.Wheels == null) throw new ArgumentException("Can't create if cars wheels is null); _car = car; _car.Wheels.Rolling += WheelsRollingHandler; } } I was struggling to describe what the problem is except that it seems wrong that a CarPresenter should attempt to dictate to a Car whether or not it's Wheels are initialised correctly. I wondered what pointers people here might give me?

  • Circumventing a manual HTML login page for "unclassified" websites (automation purposes, credentials

    - by auramo
    The IT department just made my life a little bit harder again: they introduced a manual HTML login page for all websites they have not "classified". This means that all the applications which try to access unclassified websites for e.g. downloading plugins do not work. Examples: Eclipse plugin installation, Maven builds etc. What would be the easiest workaround for this? The best I've come up with is try to extend/customize Ruby's httpproxy.rb that comes with Webrick. I would automate the manual login process whenever that login response page is detected. This sounds quite painful, and I think there might/should be simpler options?

  • C# and SQL data layer code generator

    I've created a simple yet efficient tool to help generate stored procedures and a C# data access layer from a table.  Instead of using an ORM, this uses standard ADO .NET (SqlConnection, SqlDataReader, etc).  Check it out at www.asteio.com.  It's saved me a ton of time and I'm hoping it does the same for you....Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • Structuring an input file

    - by Ricardo
    I am in the process of structuring a small program to perform some hydraulic analysis of pipe flow. As I am envisioning this, the program will read an input file, store the input parameters in a suitable way, operate on them and finally output results. I am struggling with how to structure the input file in a sane way; that is, in a way that a human can write it easily and a machine can parse it easily. A sample input file made available to me for a similar program is just a stream of comma-separated numbers that don't make much sense on their own, so that's the scenario I am trying to avoid. Though I am giving the details of my particular problem, I am more interested in general input-file structuring strategies. Is a stream of comma-separated values my best bet? Would I be better off using some sort of key:value structure? I don't know much about this, so any help will probably put me in a better track than I am now.

  • how to serialize function depending on what instance of object calls it, if same instance call in a thread then do serialize else not

    - by LondonDreams
    I have a function which fetches and updates some record from db and I am trying to make sure each if the function is called by same instance of object(same Or different thread) then function should behave synchronized else its a call from different object instance function need not to be synchronized. I have tried it use a lock per client. That is, instead of synchronizing the method directly using explicit locking through lock objects using Map. function is like :- getAndUpdateMyHitCount(myObjId){ //go to db and get unique record by myObjId //fetch value , increment , save update } And this function may get call is same thread by different Or same object instance But as fetching and matching from Map is slow , Is there other optimized way to do this ? Found similar at this Question but dont feel that is optimized

  • Organizing your Data Access Layer

    - by nighthawk457
    I am using Entity Framework as my ORM in an ASP.Net application. I have my database already created so ended up generating the entity model from it. What is a good way to organize files/classes in the data access layer. My entity framework model is in a class library and I was planning on adding additional classes per Entity(i.e per database table) and putting all the queries related to those tables in their respective classes. I am not sure if this is a right approach and if it is then where do the queries requiring data from multiple tables go? Am I completely wrong in organizing my files based on entities/tables and should I organize them based on functional areas instead.

  • Continuing to code on large projects

    - by user3487347
    I am a hobbyist programmer, and I've started many medium - sized projects to work on just by myself. These include games, a raytracer, physics simulations etc. By the time these projects get to a certain size (around 5000 lines), I begin to slow down in adding features to the program. This is not because of a lack of ideas of what to implement in a program, but rather a struggle in how to go about it. In particular, I'm afraid of breaking what I already have working in order to implement a new feature. I've tried using version control like Git and Subversion, but these seem unnecessary when you are a one man team. I simply have a folder of "versions" of my program, one for each major change I make. How do I keep coding past this 5000 line mark? What about the 50000 line mark?

  • Is this a violation of the Liskov Substitution Principle?

    - by Paul T Davies
    Say we have a list of Task entities, and a ProjectTask sub type. Tasks can be closed at any time, except ProjectTasks which cannot be closed once they have a status of Started. The UI should ensure the option to close a started ProjectTask is never available, but some safeguards are present in the domain: public class Task { public Status Status { get; set; } public virtual void Close() { Status = Status.Closed; } } public ProjectTask : Task { public override void Close() { if (Status == Status.Started) throw new Exception("Cannot close a started Project Task"); base.Close(); } } Now when calling Close() on a Task, there is a chance the call will fail if it is a ProjectTask with the started status, when it wouldn't if it was a base Task. But this is the business requirements. It should fail. Can this be regarded as a violation?

  • gzip compression good or bad?

    - by WarDoGG
    I have a server that currently does a lot of processing in my application and the target users are those who have a very good internet connection. The output that is sent from the server is always text/html and we do not use any media (audio/video) only images (static site images like logo,etc). We are experiencing severe performance issues and I wonder if turning off gzip/mod_deflate on the server so that the server would avoid compressing the output. Will this cause an improvement in performance?

  • Long lines of text in source code [closed]

    - by ale
    Possible Duplicate: Is the 80 character limit still relevant in times of widescreen monitors? I used to set a vertical line set at 80 characters in my text editor and then I added carriage returns if the lines got too long. I later increased the value to 135 characters. I started using word wrap and not giving myself a limit but tried to keep lines short if I could because it took a lot of time shortening my lines. People at work use word wrap and don't give themselves a limit.. is this the correct way? What are you meant to do ? Many thanks.

  • FeedDaemon and Tweetdeck not opening links in Chrome but opening in IE when IE is set default browser

    - by user2059078
    A while ago a Chrome version update failed and I ended up having a program called new_chrome.exe in the folder where chrome.exe used to be. I was very busy at that moment and I continued to work without bothering to try to fix the problem. Apparently recently another update came out and the new_chrome.exe is now gone, it was replaced by chrome.exe. Since the last upgrade happened two applications that I use a lot (not sure if others do the same) do now work anymore as they used to when I try to open links. These two apps are Tweetdek and Feedaemon. If I change the default browser to Internet Explorer they both open the links when I click on them I tried everything I could but it did not work: My Default programs look like this: and my set Default Programs looks like this: How can I fix this?

  • Best way to reuse common functions between ASPX pages ?

    - by DFord
    I have a bunch of functions that are used across multiple ASPX files. I want to condense these down to one file to be used for all the ASPX files. I have a few ideas but I want to know what the accepted method to doing this would be. I have an idea to just create a class to put them in. However, I was wondering if i could put them in a ascx page, but that does not look like the solution I'm looking for. Is there a accepted method for this type of situation?
