  • java.io.FileNotFoundException for valid URL

    - by Alexei
    Hello. I use library rome.dev.java.net to fetch RSS. Code is URL feedUrl = new URL("http://planet.rubyonrails.ru/xml/rss"); SyndFeedInput input = new SyndFeedInput(); SyndFeed feed = input.build(new XmlReader(feedUrl)); You can check that http://planet.rubyonrails.ru/xml/rss is valid URL and the page is shown in browser. But I get exception from my application java.io.FileNotFoundException: http://planet.rubyonrails.ru/xml/rss at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1311) at com.sun.syndication.io.XmlReader.<init>(XmlReader.java:237) at com.sun.syndication.io.XmlReader.<init>(XmlReader.java:213) at rssdaemonapp.ValidatorThread.run(ValidatorThread.java:32) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:619) I don't use any proxy. I get this exception on my PC and on the production server and only for this URL, other URLs are working.

    - by user3702405
    I have implemented a new routing protocol named AODV2 in ns-2.35. I am using ns-2.35 in fedora 13. All .cc files have a .o file with them that means recompilation is done.

Error is shown below: trace/cmu-trace.o: In function hdr_aodv2::access(Packet const*)': cmu-trace.cc:(.text._ZN9hdr_aodv26accessEPK6Packet[hdr_aodv2::access(Packet const*)]+0x7): undefined reference tohdr_aodv2::offset_2' collect2: ld returned 1 exit status make: * [ns] Error 1 I don't know how to remove this error, Can anyone help me please? Thanks, Naeem

  • How to simulate a dial-up connection for testing purposes?

    - by mawg
    I have to code a server app where clients open a TCP/IP socket, send some data and close the connection. The data packets are small < 100 bytes, however there is talk of having them batch their transactions and send multiple packets. How can I best simulate a dial-up ut connection (using Delphy & Indy components, just FYI)? Is it as simple as open connection wait a while (what is the definition of "a while"?) close connection

  • Increasing speed of webservice - howto

    - by Koran
    Hi, Our client-server product has the protocol between them as XML over HTTP. Here, the client asks a GET/POST query to the web server and the server responds with XML. The server is written using django. The server has to be on the web because there are many clients across the world using this. The server code uses extensive memoization and also there is very less db queries - most queries dont have any db queries, some of them has max 1. The biggest problem is the speed. Every query takes close to 5 seconds for the reply. The data replied is also very less - in the range of 4-6 Kb. What are the mechanisms to improve speed of the web service? Is this the usual way of writing a client-server? Are there other technologies and are we missing out on it? Thank you K

  • Server-side technology for a game

    - by Soonts
    We’re creating a massively-multiplayer social game. We expect up to 1 million concurrent users. The game is not real-time, instead it’s turn-based. We need reliable messaging between our clients and the server, preferably over HTTP protocol. Besides the multiplayer functionality, we’ll also need a content delivery service. Could you please recommend a server-side technology for us, so we’ll start searching for the right people to hire? Is it correct assumption that no single server will hold that amount of load so it must scale horizontally? Will Windows Azure do the job? Thanks in advance.

  • XML - how to use namespace prefixes

    - by Asbie
    I have this XML at http://localhost/file.xml: <?xml version="1.0" encoding="utf-8"?> <val:Root xmlns:val="http://www.hw-group.com/XMLSchema/ste/values.xsd"> <Agent> <Version>2.0.3</Version> <XmlVer>1.01</XmlVer> <DeviceName>HWg-STE</DeviceName> <Model>33</Model> <vendor_id>0</vendor_id> <MAC>00:0A:DA:01:DA:DA</MAC> <IP>192.168.1.1</IP> <MASK>255.255.255.0</MASK> <sys_name>HWg-STE</sys_name> <sys_location/> <sys_contact> HWg-STE:For more information try http://www.hw-group.com </sys_contact> </Agent> <SenSet> <Entry> <ID>215</ID> <Name>Home</Name> <Units>C</Units> <Value>27.7</Value> <Min>10.0</Min> <Max>40.0</Max> <Hyst>0.0</Hyst> <EmailSMS>1</EmailSMS> <State>1</State> </Entry> </SenSet> </val:Root> I am trying to read this from my c# code: static void Main(string[] args) { var xmlDoc = new XmlDocument(); xmlDoc.Load("http://localhost/file.xml"); XmlElement root = xmlDoc.DocumentElement; // Create an XmlNamespaceManager to resolve the default namespace. XmlNamespaceManager nsmgr = new XmlNamespaceManager(xmlDoc.NameTable); nsmgr.AddNamespace("val", "http://www.hw-group.com/XMLSchema/ste/values.xsd"); XmlNodeList nodes = root.SelectNodes("/val:SenSet/val:Entry"); foreach (XmlNode node in nodes) { string name = node["Name"].InnerText; string value = node["Value"].InnerText; Console.Write("name\t{0}\value\t{1}", name, value); } Console.ReadKey(); } } Problem is that the node is empty. I understand this is a common newbie problem when reading XML, still not able to solve what I am doing wrong, probably something with the Namespace "val" ?

  • How to improve workflow for creating a Lua-based Wireshark dissector

    - by piyo
    I've finally created a Dissector for my UDP protocol in Lua for Wireshark, but the work flow is just horrendous. It consists of editing my custom Lua file in my editor, then double-clicking my example capture file to launch Wireshark to see the changes. If there was an error, Wireshark informs me via dialogs or a red line in the Tree analysis sub-pane. I then re-edit my custom Lua file and then close that Wireshark instance, then double-click my example capture file again. It's like compiling a C file and only seeing one compiler error at a time. Is there a better (faster) way of looking at my changes, without having to restart Wireshark all the time? At the time, I was using Wireshark 1.2.9 for Windows with Lua enabled.

  • What is the fastest way to display an image in QT on X11 without OpenGL?

    - by msh
    I need to display a raw image in a QT widget. I'm running X11 on a framebuffer, so OpenGL is not available. Both the image and the framebuffer are in the same format - RGB565, but I can change it to any other format if needed. I don't need blending or scaling. I just need to display pixels as is. I'm using QPainter::drawImage, but it converts QImage to QPixmap and this conversion seems to be very slow. Also it is backed by Xrender and I think there is unnecessary overhead required to support blending in Xrender which I don't really need Is there any better way? If it is not available in QT, I can use Xlib or any other library or protocol. I can modify the driver, X server or anything else.

  • Is It Possible to get a (rough) Mobile Phone Location from a HTTP Request

    - by Tim Lytle
    If memory serves me correctly, google does this for the maps site. I know google's mobile maps app can determine the rough location (I assume using some kind of cell tower lookup), yet I seem to remember the site getting somewhat close to the current location when viewing on a mobile browser. Anyone know how/if that's possible? Does the IP address change based on the tower or area (seems like they'd be using some kind of gateway common to the carrier)?

  • Security & Authentication: SSL vs SASL

    - by 4herpsand7derpsago
    My understanding is that SSL combines an encryption algorithm (like AES, DES, etc.) with akey exchange method (like Diffier-Hellman) to provide secure encryption and identification services between two endpoints on an un-secure network (like the Internet). My understanding is that SASL is an MD5/Kerberos protocol that pretty much does the same thing. So my question: what are the pros/cons to choosing both and what scenarios make both more preferable? Basically, I'm looking for a guidelines to follow when choosing SSL or to go with SASL instead. Thanks in advance!

  • my realtime network receiving time differs a lot, anyone can help?

    - by sguox002
    I wrote a program using tcpip sockets to send commands to a device and receive the data from the device. The data size would be around 200kB to 600KB. The computer is directly connected to the device using a 100MB network. I found that the sending packets always arrive at the computer at 100MB/s speed (I have debugging information on the unit and I also verified this using some network monitoring software), but the receiving time differs a lot from 40ms to 250ms, even if the size is the same (I have a receiving buffer about 700K and the receiving window of 8092 bytes and changing the window size does not change anything). The phenomena differs also on different computers, but on the same computer the problem is very stable. For example, receiving 300k bytes on computer a would be 40ms, but it may cost 200ms on another computer. I have disabled firewall, antivirus, all other network protocol except the TCP/IP. Any experts on this can give me some hints?

  • Using WAMP's MySQL with Cygwin Ruby on Rails

    - by Andrei
    I'm trying to install a Rails app on a Cygwin Rails + WAMP MySQL setup, but rake trows an error : Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2) Of course, it's trying to connect to MySQL trought a Cygwin socket, and since there's no MySQL server running on Cygwin, it fails. How do I get Rails to connect to WAMP's MySQL (perhaps through TCP/IP instead of a socket) ?

  • I'm using the correct content type & Headers so Why is FireFox saving Zip Files without extensions

    - by The_AlienCoder
    Users on my site have the option to download all the photos in an album as a zip file.The Zip file is dynamically created and saved to Response.OutPutStream to be detected as a file download on the user's browser. Here is the Header and Content-type I am outputing context.Response.AddHeader("Content-Disposition", "attachment; filename=Photos.zip"); context.Response.ContentType = "application/x-zip-compressed"; ..Well everything works fine with every browser except FireFox. Although Firefox correctly detects the download as a Zip file, It saves the file without the .zip extension. I thought adding this header context.Response.AddHeader("Content-Disposition", "attachment; filename=Photos.zip"); ..is supposed to force FF to save the extension. I believe I am following the correct protocol so why is FF behaving this way and how do I fix this?

  • Php - please help to find two alternatives for ereg functions

    - by Guanche
    ereg and eregi functions will be deleted from Php. Please help to find alternatives for the following ereg functions: 1) To allow IP addresses only for specific ranges: $targetAddr = "60.37..*..*"; if (!ereg($targetAddr, $_SERVER['REMOTE_ADDR'])) { die; } 2) To replace series of points like ....................... $message = ereg_replace("[.]{3,}", "...

  • Gruber URL Regex tweak to capture "domain.com"

    - by mootymoots
    I found an updated version of John Gruber's regex for url matching in this post by user GianPac, which states it's been adapted to recognize url without protocol or the www part: (?i)\b((?:[a-z][\w-]+:(?:/{1,3}|[a-z0-9%])|www\d{0,3}[.]|[a-z0-9.-]+[.][a-z]{2,4}/?)(?:[^\s()<]+|(([^\s()<]+|(([^\s()<]+)))))(?:(([^\s()<]+|(([^\s()<]+))))|[^\s`!()[]{};:'\".,<?«»“”‘’])) Whilst this works in most cases, I found it does not match "google.com". It does match "google.comm" and "google.co.uk", so this must be a small oversight. The trouble is, I literally hate regex. It's the bane of my life. I just want to try and tweak this one more time to allow for "google.com" - can anyone throw me a pointer? I (think) it's something to do with this part of the code: +[.][a-z]{2,4}/?) ?

  • How to implement a syndication receiver? (multi-client / single server)

    - by LeonixSolutions
    I have to come up with a system architecture. A few hundred remote devices will be communicating over internet with a central server which will receive data and store it in a database. I could write my own TCP/IP based protocol use SOAP use AJAX use RSS anything else? This is currently seen as one way (telemetry, as opposed to SCADA). Would it make a difference if we make it bi-directional. There are no plans to do so, but Murphy's law makes me wary of a uni-directional solution (on the data plane; I imagine that the control plane is bi-directional in all solutions (?)). I hope that this is not too subjective. I would like a solution which is quick and easy to implement and for others to support and where the general "communications pipeline" from remote deceives to database server can be re-used as the core of future projects. I have a strong background in telecomms protocols, in C/C++ and PHP.

  • Ideas on simulating webservices for local automated testing.

    - by novice123
    I am testing an app, which talks to different webservices over the internet. For my automated testing, I don't want to go over the network. To achieve this, I need to simulate the webservice on my machine using another app. My initial thought is to record all the requests and responses between client and webservice, and then just write a simulation app which replays these responses. The disadvantage here is that everytime the webservice protocol changes a bit, I have to modify all my recorded resposnes. so I am looking to see if there are more elegant solutions. have anyone solved a similar problem? any thoughts, suggestion are appreciated.

  • SQL Server: error when connecting

    - by atricapilla
    The application I'm using tries to connect SQL Server named instance running on a dedicated database server. Here's the error I'm getting: The TCP/IP connection to the host <instance_name>, port 1433 has failed. Error: Connection refused: connect. Is the firewall blocking my access or what? Should I dedicate a different port for this application?

I see he is saving the user ip, user agent and referrer, but am confused with the req=(request) line. Any help is appreciated. Thanks
