  • recovering raid 0 hard disk

    - by Hiawatha
    I bumped to a huge (for me) problem. I was running dual boot system (win 7 / linux) and at some point I decided to test fedora ( I am new in Linux ). My hard disk conf: 3 hard disks each 1 TB, 2 set to raid 0 with windows running on it and 1 for linux. After installing it from live usb I found out that windows 7 is not in grub anymore and while booting shows raid error. I installed back Ubuntu and ran Disk Utility and checked now I have one disks (raid 0) failed (READ) error. First has 5 bad sectors and second has 1 bad sector. And now I dont know what to do and how to repair. further I dont know which data i could provide to get help. I tried ntfsfix and got this output: Mounting volume... NTFS signature is missing. FAILED Attempting to correct errors... NTFS signature is missing. FAILED Failed to startup volume: Invalid argument NTFS signature is missing. Trying the alternate boot sector Unrecoverable error Volume is corrupt. You should run chkdsk. #sudo ntfs-3g -o force,rw /dev/sdb /media/windows NTFS signature is missing. Failed to mount '/dev/sdb': Invalid argument The device '/dev/sdb' doesn't seem to have a valid NTFS. Maybe the wrong device is used? Or the whole disk instead of a partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?

  • what will EcmaScript 6 bring to the table for us

    - by user697296
    Our company ported moderate chunks of business logic to JavaScript. We compile the code with a minifier, which further improves performance. Since the language is dynamically typed, it lends itself well to obfuscation, which occurs as a byproduct of minification. We went to great efforts to ensure it positively screams, performance-wise. We can now do what we did before, faster, better, with less code, on more platforms. In summary, we are very satisfied with the current state of the language. I personally love the language especially for its cross-platform nature. So naturally, I read up a lot about the state of JavaScript compilers, performance and compatibility across as many browsers and platforms as I have time to research. The one theme which has been growing louder and louder these days, is the news about ECMAScript 6. So far, what I have been able to gather is that ES6 promises a better development experience; firstly by enabling new ways to do things, secondly by reporting errors early. This sounds great for those who are still waiting for the language to meet their needs before jumping on board. But we have already jumped on board in a big way. Sure, I expect that we will have to do ongoing maintenance and feature revisions on our code through the years, and that we would obviously make use of best practices at the time. But I don't see us refactoring major portions of it to take advantage of language features that are mostly intended to boost developer productivity. I keep wondering, what impact will the language advances ultimately have on our existing, well-written, well-performing code base? Is there something I am missing? Is there something we ought to look out for? Does anyone have tips or guidance on how we should approach the ecmascript.next finalization? Should we care?

  • How do I get my Intel HD graphics to work alongside my HD7850, as my second(HDMI out) monitor?

    - by AlexTes
    Title says it all. Further info: Motherboard: http://www.asrock.com/mb/Intel/Z77%20Pro3/ Processor: http://ark.intel.com/products/65520/Intel-Core-i5-3570K-Processor-%286M-Cache-up-to-3_80-GHz%29 So currently my main screen is running on my HD7850. Got drivers from the amd website. I have looked through dozens of questions here. I'm about to try booting Ubuntu from a stick and seeing if the xorg-edgers drivers might help. When booting, all action goes down on the very screen I'm trying to get to work.*EDIT never mind this. Seems to be special boot magic. As the screen only displays whiteline errors once the gui of ubuntu has kicked in and everything graphic is happening through my graphics card again. Connected through HDMI(motherboard)-DVI. So unless having multiple displays is a huge deal the solution hopefully isn't that complicated. I just feel I'm missing something simple. If this really is complicated, I should probably just hook up the display to my graphics card. My CPU is usually the one chilling out though so I'd like to try to get that to work. Also just because I don't want to buy an extra cable and this set up makes me feel warm and fuzzy inside. Tell me what to try or look up, I'll be most appreciative. Thank you! **UPDATE The x-swat ppa installed some intel stuff. Booting with one monitor plugged into the motherboard gives nothing. Doing it with the pc already on gives the purple "Ubuntu" with 5 dots boot/shutdown screen.

  • Do there exist programming languages where a variable can truly know its own name?

    - by Job
    In PHP and Python one can iterate over the local variables and, if there is only once choice where the value matches, you could say that you know what the variable's name is, but this does not always work. Machine code does not have variable names. C compiles to assembly and does not have any native reflection capabilities, so it would not know it's name. (Edit: per Anton's answer the pre-processor can know the variable's name). Do there exist programming languages where a variable would know it's name? It gets tricky if you do something like b = a and b does not become a copy of a but a reference to the same place. EDIT: Why in the world would you want this? I can think of one example: error checking that can survive automatic refactoring. Consider this C# snippet: private void CheckEnumStr(string paramName, string paramValue) { if (paramName != "pony" && paramName != "horse") { string exceptionMessage = String.Format( "Unexpected value '{0}' of the parameter named '{1}'.", paramValue, paramName); throw new ArgumentException(exceptionMessage); } } ... CheckEnumStr("a", a); // Var 'a' does not know its name - this will not survive naive auto-refactoring There are other libraries provided by Microsoft and others that allow to check for errors (sorry the names have escaped me). I have seen one library which with the help of closures/lambdas can accomplish error checking that can survive refactoring, but it does not feel idiomatic. This would be one reason why I might want a language where a variable knows its name.

  • 12.04 LTS Apache2 writing files from webpage at runtime has no effect - possible read/write permissions?

    - by J Green
    I'm running 12.04LTS with Apache and Mono in VirtualBox, with the goal of hosting a web app (coded in ASP.NET and C#) on my local network. The scripts on the page are able to successfully read from text files in the same directory as my site (/var/www/mysite/) but do not seem to be able to write. I'm sure the code works, because it did with my testing in Visual Web Developer on Windows. I don't get any errors, but when I click the button on the loaded webpage, the text file in question does not change. I'm fairly new to Linux in general, so I'm not too familiar with how to set permissions properly, and it may be a permissions issue. Unfortunately, I have searched all over the internet and haven't found a solution that worked, but I've tried (perhaps incorrectly) changing the owner of the files in question to www-root, changing the mode to a+rw, but sadly to no avail. I have tried everything here but it doesn't work: Whats the simplest way to edit and add files to "/var/www"? I hope someone can help me out.

  • Win7 and Ubuntu refuse to coexist

    - by Jeremy
    I'll make this quick: I have an HP laptop with win7, I installed Ubuntu on a separate partition, and when I tried to boot win7 from grub I got the loading screen and no progress-ever. I did a /fixmbr with the windows recovery cd and got back windows, but wiped out grub and my access to Ubuntu. I reinstalled grub from the Ubuntu live usb ( I know I did this correctly) and now windows won't boot, again. I'm a linux noob at a loss. Your wisdom is greatly appreciated! Update in response to Scott Severance: your instructions say to determine the main partition on my computer. I'm not sure what this means... my windows partition is at sda2, my boot partition is at sda1, and my linux root partition is at sda7... Which is the "main" partition? UPDATE: I determined that you were probably referring to the linux root(/) partition, because this was the only partition for which I could follow your instructions without errors. Now, Windows is booting fine (thanks to /fixmbr), but even after the grub instructions there is no grub. It boots straight into windows.

  • Boot failure on Ubuntu 11.04

    - by B Seven
    I was using my laptop with Ubuntu without problem for a few months. I did not update any software or install any OS updates. This morning when it started, I got error: no such device:.... error: no such disk error: you need to load the kernel first. Press any key to continue... Then takes me back to GRUB menu. Both Ubuntu option and recovery mode option show the same thing (above). What does this mean? How do I fix it? Since I did not install anything new, does it mean the SSD is dying (again)? How to check the SSD to and fix any file system errors? Ubuntu 11.04 EDIT: Just remembered something: when the system was shutting down, it did not turn off. There were a bunch of weird output statements, and I assumed the system had shut down so I turned it off with the power button. Perhaps something got corrupted because of that.

  • Fourth texture = segmentation fault

    - by Robin92
    I keep on getting segmentation fault each time I load fourth texture - what type of texture, I mean filename, does not matter. I checked value of GL_TEXTURES_STACK_SIZE which turned out to be 10 so quite more than 4, isn't it? Here're code fragments: funciton to load texture from png static GLuint gl_loadTexture(const char filename[]) { static int iTexNum = 1; GLuint texture = 0; img_s *img = NULL; img = img_loadPNG(filename); if (img) { glGenTextures(iTexNum++, &texture); glBindTexture(GL_TEXTURE_2D, texture); glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MIN_FILTER,GL_LINEAR); glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MAG_FILTER,GL_LINEAR); glTexImage2D(GL_TEXTURE_2D, 0, img->iGlFormat, img->uiWidth, img->uiHeight, 0, img->iGlFormat, GL_UNSIGNED_BYTE, img->p_ubaData); img_free(img); //it may cause errors on windows } else printf("Error: loading texture '%s' failed!\n", filename); return texture; } actual loading static GLuint textures[4]; static void gl_init() { (...) //setting up OpenGL /* loading textures */ textures[0] = gl_loadTexture("images/background.png"); textures[1] = gl_loadTexture("images/spaceship.png"); textures[2] = gl_loadTexture("images/asteroid.png"); textures[3] = gl_loadTexture("images/asteroid2.png"); //this is causing SegFault no matter which file I load! } Any ideas? Problem is present on both Linux and Windows.

  • Release Notes for 5/18/2012

    Here are the notes for this week’s release: Pull Requests We’ve added the ability to see the snippets of code where a user commented inline in the discussion of pull requests. You can also add another line comment directly from the discussion area, rather than navigating to the code diff viewer. Note that there’s currently a known issue where the line associated with the comment isn’t being properly differentiated for existing pull requests (the line in the middle of each diff preview should be bolded). Apologies for the inconvenience! As part of this work, we also took some time to clean up our diff viewer UI to remove the dots and introduce a new color scheme where green is used for added lines. Bug Fixes Fixed an issue affecting the ability to assign pull requests. Fixed an issue where managing various team resources for a project was not working in Chrome or Firefox. Fixed an issue where a project’s RSS subscribe dialog popped up in the wrong place. Fixed an issue where editing wiki anchor links would insert extra characters, resulting in broken links. Fixed an issue where project logos did not display correctly when browsing the site with https in Chrome or Firefox. Fixed an issue where users could encounter errors when deleting remote Git branches. Fixed an issue affecting the ability of fork collaborators to push changes to the fork. Fixed an issue where the advanced work item filters would not persist when navigating through result pages. Fixed an issue where the issue tracker notifications link was not clickable in Chrome. Fixed an issue where pull request comments with line breaks would not be formatted properly when viewing the pull request. Other We upgraded our Git servers to version 1.7.10.1.

  • dist-upgrade broke my insatll HELP

    - by diefuchsjagden
    so I ran apt-get update; apt-get dist-upgrade the upgrade failed and I lost the gui, I have an encrypted /home drive. When I run apt-get * (any command) I have all kinds of errors mostly missing depends and thats because apparently my network stack is gone. I have no NIC if I run ifconfig. It doesn't even show up with lspci If I were to do a "clean" install of 10.04 LTS which is what I had on my on my build, will I lose all my data? BTW I was just using Ubuntu's default encryption to manage the encryption using my PSWD as the key so if I were to use the same user name and PSWD would my data be accessible? I can see my data from command line, when or if Xorg does start it just loads a basic window with nothing but a black X in the middle of the screen which I can only assume is my mouse cursor but it doesn't move! Reddit /r/linux had some ideas none of which worked was, no help. And apparently /r/ubuntu is full of jerks because all they did was ridicule me. If I can get my install back I probably will be switching back to either Slackware or Gentoo. The Ubuntu forums were of no help they had the same suggestion as /r/linux. I am about to just run my back up script to my back up drives and nuke everything else but I'd rather not.

  • Just installed Ubuntu 12.04. When booting, all I get is a black screen with cursor

    - by user66378
    Installation appears to go fine. After rebooting, I get my motherboard loading screens, but when it comes time for Ubuntu to boot, I just get a black screen with a blinking white underscore in the top-left - same as I got when waiting for the install CD to load, except it lasts forever. The only keypress it seems to recognize is ctrl+alt+del, which reboots. Letters don't register, function keys w/ or w/o modifiers do nothing. I've installed Ubuntu 12.04 twice and got the same error. The first time, I installed it as the only OS, and had it take up the whole disk. The second time, I installed Windows 7 first, then Ubuntu by specifying custom partitions. After this install, it would boot straight to Windows without showing grub. I used EasyBCD to add the Ubuntu installation to grub, and this got grub to show, and let me select it, but it led back to the same error described up top. I've had Linux Mint 11 and 12 installed on this PC, but was unable to get previous versions of Ubuntu to install (always had errors while installing, not after).

  • Three Ubuntu 12.04 + Xfce problems

    - by user1708495
    sorry to bother you, but I wanted to set up a minimal Ubuntu 12.04 with minimal Xfce and probably due to my unawareness of several important things, not everything is working properly. -Sometimes when I shutdown I get error message from iwlwifi: It starts with a time out error about sending a power table and after several other errors it says "On demand firmware reload and "Unable to initialize device". And the shutdown stops there so I can only use hard shutdown. -Also when I boot, I often boot to a black screen, but pressing ctrl+alt+f1 gets me to the login prompt (I do not use a login manager). But then I sometimes cannot type. Seems probably more like a X server problem. When it works I only see the Plymouth splash for a very short time or sometimes not at all. -And the last problem is the most annoying one: Frequently Xfce freezes completely. I think ctrl+alt+f1 works sometimes, but other times I also have to use hard shutdown. When it freezes the cpu fan gets louder. I've been using Xbuntu for a while before, but with "real" Linux I am more a beginner, so I hope you forgive my questions Thanks

  • "Do it right, against customer's wishes" - how is it called?

    - by SF.
    We know the optimal situation of negotiating corrections of specifications with the customer, getting the specs to do what the client wanted, not what they said or thought they wanted. That's negotiating, explaining. Sometimes, we're unable to convince the client. We're forced to produce broken as designed. This, called "demonology" by merit of mages summoning demons and demons fulfilling their wishes very literally, causing the mage's demise as result, is another approach that will leave the customer very dissatisfied once they realize their error, and of course try to pin the blame on the developer. Now I just faced a very different approach: the customer created simple specs that fail to account for some critical caveat, and is completely unwilling to fix them, admit the obvious errors and accept suggested corrections. The product made to these specs will be critically broken, and possibly might cost human lives. Still, it's too late to drop the contract entirely. The contract has punitive clauses for that, ones we can't really accept. The boss' decision? We do the work right and lie to the customer that we did it according to the specs. The algorithms in question are hidden deep enough under the surface, the product will do the work just fine, won't fail in the caveat situation, and unless someone digs too deep, they will never discover we didn't break it as requested. Is there some common name for this tactics of execution of specs?

  • Problem installing Ubuntu 14.04 into a laptop using Windows 8.1

    - by AlexanderFreud
    I have used Ubuntu on my LG laptop for several years. I lately bought an Acer Aspire V5 laptop which included Windows 8.1. I don't have any data on it; I would like to just remove it completely (that horrible Windows 8.1) and install Ubuntu. I tried using a USB device with Ubuntu 14.04 (64bit version) saved on it. I changed the BIOS configuration, putting USB device first on boot order, Windows Boot Manager last. When I try to run with USB device it doesn't work. Messages like these show up: System doesn't have any USB boot option. Please select other boot option in Boot Manager Menu. Windows failed to start. A recent hardware or software change might be the cause. To fix the problem: 1. insert your windows installation disc and restart your computer 2. choose your language settings, and then click "next" 3. click "repair your computer" If you do not have this disk, contact your system administrator manufacturer for assistance File \ubuntu\winboot\wubildr.mbr Status: 0xc000007b Info: the application or operating system couldn't be load...[?] required file is missing or contains errors. Could someone please write step-by-step procedures to install Ubuntu 14.04 after removing Windows 8.1 ? I already have done a second partition on the hard disk just in case.

  • Ubuntu 11.10 Random reboots how to find root cause?

    - by Indigo42
    All, This issue started with 11.04, I upgraded to 11.10 this week in hopes it would correct it, but after a few days it happened again.. A few times a day, randomly, my monitors will go black and the machine will come back in the post screen and boot up again. Sometimes it boots up properly, sometimes it boots to disk scan (I understand why...the machine just died with a bunch of stuff open) and sometimes it takes several cycles of this to come up. I connected to the system with my laptop and tailed dmesg, syslog, kern.log, and Xorg.0.log. I also ran a cat /proc/kmesg. Nothing is showing up in any of these log files when it happens..it's just like someone has pulled the plug. I just got through running 4 hours of the memory test with no errors. I have a AMD Phenom 9850 Quad-Core Processor and Nvida 9500GT graphics card. This system has been stable for like 4 years. I'm thinking it might be a hardware problem, but how do I find out? Thanks,

  • ORA-00900 Super Easy Fix (for some cases)

    - by Bunch
    Here is a really easy fix for some ORA-00900 errors. Well at least the one I saw the other day. This was something that I did not come across when searching either. I found lots of other ideas on what the problem might be but not the fix. Since I am fairly new to PL/SQL (TSQL only for a long time) this one stumped me for a while. Until I asked someone and they saw the error in about two seconds. When using the Command Window to add a view I was receiving an ORA-00900 error. So I checked that everything the view was referencing was there and that the permissions looked OK. The code for the view was fairly simple and it ran just fine in a regular SQL Window. It ended up that the Command Window did not like the space I had between the list of items in the select before the from. Bad: col1,col2,                               <--- does not like the empty linefrom tblSomething Good: col1,col2,from tblSomething I will just chalk that up to my familiarity with PL/SQL.

    I was on this website: http://code.google.com/edu/languages/cpp/basics/getting-started.html#learn-by-example and I saw this code: // Description: Illustrate the use of cin to get input // and how to recover from errors. #include <iostream> using namespace std; int main() { int input_var = 0; // Enter the do while loop and stay there until either // a non-numeric is entered, or -1 is entered. Note that // cin will accept any integer, 4, 40, 400, etc. do { cout << "Enter a number (-1 = quit): "; // The following line accepts input from the keyboard into // variable input_var. // cin returns false if an input operation fails, that is, if // something other than an int (the type of input_var) is entered. if (!(cin >> input_var)) { cout << "Please enter numbers only." << endl; cin.clear(); cin.ignore(10000,'\n'); } if (input_var != -1) { cout << "You entered " << input_var << endl; } } while (input_var != -1); cout << "All done." << endl; return 0; } I was wondering... what is the significance of cin.clear() and cin.ignore() ...and also why the 10000 and /n parameters are necessary...?...

  • a c++ code for scheduling tasks [closed]

    This code has no errors but then when i execute it, there is no output and the program automatically shuts down saying the program has stopped working. #include<unistd.h> #include<stdio.h> #include<stdlib.h> #include<time.h> #include<string.h> int main() { char *timetoken; char currtime[7]; char schedtime[7]; int i; struct tm *localtimeptr; strcpy(schedtime,"15:25:00"); while(6!=9) { time_t lt; sleep(1); lt = time(NULL); localtimeptr = localtime(lt); timetoken=strtok(asctime(localtimeptr)," "); for(i=1;i<5;i++) timetoken=strtok('\0'," "); if(i==3) { strcpy(currtime,timetoken); } } printf("The current time is: %s\n",currtime); printf("We are waiting for: %s\n",schedtime); if(!strcmp(currtime,schedtime)) { printf("Time to do stuff \n"); system("C:\PROJECT X"); } getch(); return 0; }

  • data validation on wpf passwordbox:type password, re-type password

    - by black sensei
    Hello Experts !! I've built a wpf windows application in with there is a registration form. Using IDataErrorInfo i could successfully bind the field to a class property and with the help of styles display meaningful information about the error to users.About the submit button i use the MultiDataTrigger with conditions (Based on a post here on stackoverflow).All went well. Now i need to do the same for the passwordbox and apparently it's not as straight forward.I found on wpftutorial an article and gave it a try but for some reason it wasn't working. i've tried another one from functionalfun. And in this Functionalfun case the properties(databind,databound) are not recognized as dependencyproperty even after i've changed their name as suggested somewhere in the comments plus i don't have an idea whether it will work for a windows application, since it's designed for web. to give you an idea here is some code on textboxes <Window.Resources> <data:General x:Key="recharge" /> <Style x:Key="validButton" TargetType="{x:Type Button}" BasedOn="{StaticResource {x:Type Button}}" > <Setter Property="IsEnabled" Value="False"/> <Style.Triggers> <MultiDataTrigger> <MultiDataTrigger.Conditions> <Condition Binding="{Binding ElementName=txtRecharge, Path=(Validation.HasError)}" Value="false" /> </MultiDataTrigger.Conditions> <Setter Property="IsEnabled" Value="True" /> </MultiDataTrigger> </Style.Triggers> </Style> <Style x:Key="txtboxerrors" TargetType="{x:Type TextBox}" BasedOn="{StaticResource {x:Type TextBox}}"> <Style.Triggers> <Trigger Property="Validation.HasError" Value="true"> <Setter Property="ToolTip" Value="{Binding RelativeSource={RelativeSource Self}, Path=(Validation.Errors)[0].ErrorContent}"/> <Setter Property="Validation.ErrorTemplate"> <Setter.Value> <ControlTemplate> <DockPanel LastChildFill="True"> <TextBlock DockPanel.Dock="Bottom" FontSize="8" FontWeight="ExtraBold" Foreground="red" Padding="5 0 0 0" Text="{Binding ElementName=showerror, Path=AdornedElement.(Validation.Errors)[0].ErrorContent}"></TextBlock> <Border BorderBrush="Red" BorderThickness="2"> <AdornedElementPlaceholder Name="showerror" /> </Border> </DockPanel> </ControlTemplate> </Setter.Value> </Setter> </Trigger> </Style.Triggers> </Style> </Window.Resources> <TextBox Margin="12,69,12,70" Name="txtRecharge" Style="{StaticResource txtboxerrors}"> <TextBox.Text> <Binding Path="Field" Source="{StaticResource recharge}" ValidatesOnDataErrors="True" UpdateSourceTrigger="PropertyChanged"> <Binding.ValidationRules> <ExceptionValidationRule /> </Binding.ValidationRules> </Binding> </TextBox.Text> </TextBox> <Button Height="23" Margin="98,0,0,12" Name="btnRecharge" VerticalAlignment="Bottom" Click="btnRecharge_Click" HorizontalAlignment="Left" Width="75" Style="{StaticResource validButton}">Recharge</Button> some C# : class General : IDataErrorInfo { private string _field; public string this[string columnName] { get { string result = null; if(columnName == "Field") { if(Util.NullOrEmtpyCheck(this._field)) { result = "Field cannot be Empty"; } } return result; } } public string Error { get { return null; } } public string Field { get { return _field; } set { _field = value; } } } So what are suggestion you guys have for me? I mean how would you go about this? how do you do this since the databinding first purpose here is not to load data onto the fields they are just (for now) for data validation. thanks for reading this.

  • Why isn't the Spring AOP XML schema properly loaded when Tomcat loads & reads beans.xml

    - by chrisbunney
    I'm trying to use Spring's Schema Based AOP Support in Eclipse and am getting errors when trying to load the configuration in Tomcat. There are no errors in Eclipse and auto-complete works correctly for the aop namespace, however when I try to load the project into eclipse I get this error: 09:17:59,515 WARN XmlBeanDefinitionReader:47 - Ignored XML validation warning org.xml.sax.SAXParseException: schema_reference.4: Failed to read schema document 'http://www.springframework.org/schema/aop/spring-aop-2.5.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not . Followed by: SEVERE: StandardWrapper.Throwable org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 39 in XML document from /WEB-INF/beans.xml is invalid; nested exception is org.xml.sax.SAXParseException: cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'aop:config'. Caused by: org.xml.sax.SAXParseException: cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'aop:config'. Based on this, it seems the schema is not being read when Tomcat parses the beans.xml file, leading to the <aop:config> element not being recognised. My beans.xml file is as follows: <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jaxws="http://cxf.apache.org/jaxws" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd"> <!--import resource="classpath:META-INF/cxf/cxf.xml" /--> <!--import resource="classpath:META-INF/cxf/cxf-extension-soap.xml" /--> <!--import resource="classpath:META-INF/cxf/cxf-servlet.xml" /--> <!-- NOTE: endpointName attribute maps to wsdl:port@name & should be the same as the portName attribute in the @WebService annotation on the IWebServiceImpl class --> <!-- NOTE: serviceName attribute maps to wsdl:service@name & should be the same as the serviceName attribute in the @WebService annotation on the ASDIWebServiceImpl class --> <!-- NOTE: address attribute is the actual URL of the web service (relative to web app location) --> <jaxws:endpoint xmlns:tns="http://iwebservices.ourdomain/" id="iwebservices" implementor="ourdomain.iwebservices.IWebServiceImpl" endpointName="tns:IWebServiceImplPort" serviceName="tns:IWebService" address="/I" wsdlLocation="wsdl/I.wsdl"> <!-- To have CXF auto-generate WSDL on the fly, comment out the above wsdl attribute --> <jaxws:features> <bean class="org.apache.cxf.feature.LoggingFeature" /> </jaxws:features> </jaxws:endpoint> <aop:config> <aop:aspect id="myAspect" ref="aBean"> </aop:aspect> </aop:config> </beans> The <aop:config> element in my beans.xml file is copy-pasted from the Spring website to try and remove any possible source of error Can anyone shed any light on why this error is occurring and what I can do to fix it?
