  • how to configure jetty 7 to use syslog or log4j

    - by egemen ozden
    I am looking for a way to direct all the jetty 7 logging to syslog. My current configuration dumps everything to JETTY_HOME/logs/.. After some initial ivestigation, it seems I should change JETTY_HOME/etc/jetty-logging.xml, but this does not look straightforward. It looks like I should create a new PrintStream implementation which sends its output to syslog and redirecting stderr and stdout to that class in jetty-logging.xml. any easier way to do that or to make jetty log directly to log4j ? Thanks

  • Somewhere to download CSS coverflow?

    - by Mark
    This is my favorite coverflow: http://paulbakaus.com/lab/js/coverflow/ Is there some way to download this? Or is there an implementation guide? All I see are some blog posts with nothing on how to implement. Thanks.

  • IVsEditorAdaptersFactoryService.CreateVsTextViewAdapter throws an object null reference

    - by Adam Driscoll
    I'm trying to create a IVsTextViewAdpater with the IVsEditorAdaptersFactoryService but when I call CreateVsTextViewAdapter it throws an object null reference: var editorFactory = componentModel.GetService<IVsEditorAdaptersFactoryService>(); var serviceProvider = (Microsoft.VisualStudio.OLE.Interop.IServiceProvider)this; var view = editorFactory.CreateVsTextViewAdapter(serviceProvider); 'this' is a Microsoft.VisualStudio.Shell.Package implementation. Any ideas?

  • How to approach performance issues?

    - by jess
    Hi, We are developing a client-server desktop application(winforms with sql server 2008, using LINQ-SQL).We are now finding many issues related to performance.These relate to querying too much data with LINQ , bad database design,not much caching etc.What do you suggest,we should do - how to go about solving these performance issues? One thing,I am doing is doing sql profiling,and trying to fix some queries.As far caching is concerned,we have static lists.But,how to keep them updated,we don't have any server side implementation.So,these lists can be stale,if someone changes data. regards

  • Xsl mime type problem

    - by savruk
    Hi, I have a busybox with lighttpd running on as http server. My problem is while firefox and opera can get the page with applied xsl, Arora(webkit) can not. Here is the script I use to get it work: <html> <head> <script> function loadXMLDoc(dname) { if (window.XMLHttpRequest) { xhttp=new XMLHttpRequest(); } else { xhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xhttp.open("GET",dname,false); xhttp.send(""); return xhttp.responseXML; } function querySt(ji) { hu = window.location.search.substring(1); gy = hu.split("&"); for (i=0;i<gy.length;i++) { ft = gy[i].split("="); if (ft[0] == ji) { return ft[1]; } } } function displayResult() { xml=loadXMLDoc("sample.xml"); alert(xml)//Gives [object Document] $scan=querySt("scan"); $sub = querySt("sub"); xsl=loadXMLDoc("sample.xsl"); alert(xsl)//Gives Null // code for IE if (window.ActiveXObject) { ex=xml.transformNode(xsl); document.getElementById("example").innerHTML=ex; } // code for Mozilla, Firefox, Opera, etc. else if (document.implementation && document.implementation.createDocument) { xsltProcessor=new XSLTProcessor(); xsltProcessor.importStylesheet(xsl); xsltProcessor.setParameter(null,"scan",$scan) if($sub != ""){ xsltProcessor.setParameter(null,"sub",$sub) } resultDocument = xsltProcessor.transformToFragment(xml,document); document.getElementById("example").appendChild(resultDocument); } } </script> </head> <body onload="displayResult()"> <div id="example" ></div> </body> </html> I tried to see if it load xsl well and put an alert(xsl) but it gives null. Other browser can get xml and xsl files perfectly. What can be the problem? Thanks P.S: It runs well on my local server with all browser.

  • Error with varchar(max) column when using net.sourceforge.jtds.jdbc.Driver

    - by Rihan Meij
    Hi I have a MS SQL database running (MS SQL 2005) and am connecting to it via the net.sourceforge.jtds.jdbc.Driver. The query works fine for all the columns except one that is a varchar(max). Any ideas how to get around this issues? I am using the jdbc driver to run a data index into a SOLR implementation. (I do not control the database, so the first prize solution would be where I can tweak the SQL command to get the desired results) Thanks

  • Variable sized packet structs with vectors

    - by Rev316
    Lately I've been diving into network programming, and I'm having some difficulty constructing a packet with a variable "data" property. Several prior questions have helped tremendously, but I'm still lacking some implementation details. I'm trying to avoid using variable sized arrays, and just use a vector. But I can't get it to be transmitted correctly, and I believe it's somewhere during serialization. Now for some code. Packet Header class Packet { public: void* Serialize(); bool Deserialize(void *message); unsigned int sender_id; unsigned int sequence_number; std::vector<char> data; }; Packet ImpL typedef struct { unsigned int sender_id; unsigned int sequence_number; std::vector<char> data; } Packet; void* Packet::Serialize(int size) { Packet* p = (Packet *) malloc(8 + 30); p->sender_id = htonl(this->sender_id); p->sequence_number = htonl(this->sequence_number); p->data.assign(size,'&'); //just for testing purposes } bool Packet::Deserialize(void *message) { Packet *s = (Packet*)message; this->sender_id = ntohl(s->sender_id); this->sequence_number = ntohl(s->sequence_number); this->data = s->data; } During execution, I simply create a packet, assign it's members, and send/receive accordingly. The above methods are only responsible for serialization. Unfortunately, the data never gets transferred. Couple of things to point out here. I'm guessing the malloc is wrong, but I'm not sure how else to compute it (i.e. what other value it would be). Other than that, I'm unsure of the proper way to use a vector in this fashion, and would love for someone to show me how (code examples please!) :) Edit: I've awarded the question to the most comprehensive answer regarding the implementation with a vector data property. Appreciate all the responses!

  • Changing the color of a QTextBlock that is within a QTextDocument

    - by yan bellavance
    Is there any other way to change the QTextLayout of a QTextBlock that is within a QTextDocument without having to subclass QAbstractTextDocumentLayout and call its documentChanged? I know that on a call to QTextBlock::layout() const ; the returned QTextLayout object can only be modified from the documentChanged implementation of a QAbstractTextDocumentLayout subclass but I was wodering if there was any other way before I implemented it.

  • How does 'binding' in JSF work?

    - by Roman
    I've created custom component which shows chart. Now I need to make binding support for this component i.e. generated chart-image should be available (as array of bytes) to backing bean via binding mechanism. I'd like to know some general info about binding implementation techniques. Any links and examples are welcome as well. Thanks in advance!

  • Which web crawler to use to save news articles from a website into .txt files?

    - by brokencoding
    Hi, i am currently in dire need of news articles to test a LSI implementation (it's in a foreign language, so there isnt the usual packs of files ready to use). So i need a crawler that given a starting url, let's say http://news.bbc.co.uk/ follows all the contained links and saves their content into .txt files, if we could specify the format to be UTF8 i would be in heaven. I have 0 expertise in this area, so i beg you for some sugestions in which crawler to use for this task.

  • Why do switch statements continue after case

    - by John W.
    After evaluating a case in a switch statement in Java (and I am sure other languages) the following case's are also evaluated unless a control statement like break, or return is used. I understand this is probably an implementation detail, but what is/are the reasons for having this functionality happen? Thanks!

  • Google App Engine Memcache - Sliding expiration

    - by Keyur
    Is there support for sliding expiration in the GAE MemcacheService? I can do a crude implementation where following every get() I do a put(). This will effectively reset the expiration time but this obviously is not an efficient solution. Any pointers on how I can implement this more efficiently? Thanks, Keyur

  • Python or Ruby for webbased Artificial Intelligence?

    - by Pieter Kubben
    A new web application may require adding Artificial Intelligence (AI) in the future, e.g. using ProLog. I know it can be done from a Java environment, but I am wondering about the opportunities with modern web languages like Ruby or Python. The latter is considered to be "more scientific" (at least used in that environment), but using Google there seems to be a preliminary ProLog implementation for both. Any suggestions on modern (open source) web languages (like Python or Ruby) in combination with AI?

  • Message Queue with 'Message Barrier' Feature?

    - by Lajos Nagy
    Is there a message queue implementation that allows breaking up work into 'batches' by inserting 'message barriers' into the message stream? Let me clarify. No messages after a message barrier should be delivered to any consumers of the queue, until all messages before the barrier are consumed. Sort of like a synchronization point. I'd also prefer if all consumers received notification when they reached a barrier. Anything like this out there?
