  • Sending a file over web service from java to .net

    - by Goran
    Hello, I have built .NET 1.1 Web Service which should accept files and save them. Here is the code of the webmethod: [WebMethod] public bool SaveDocument(Byte[] docbinaryarray, string docname) { string dirPath = @"C:\Temp\WSTEST\"; if(!Directory.Exists(dirPath)) { Directory.CreateDirectory(dirPath); } string filePath = dirPath + docname; FileStream objfilestream = new FileStream(filePath, FileMode.Create, FileAccess.ReadWrite); objfilestream.Write(docbinaryarray, 0, docbinaryarray.Length); objfilestream.Close(); return true; } When I make a client in .NET with reference to this Web service everything goes great, but when a college of mine tries to send me a file from a JAVA client I don't get the actuall file. All I get is byte array with only one element. Definition of byte array for file, in WSDL looks like this: <s:element minOccurs="0" maxOccurs="1" name="docbinaryarray" type="s:base64Binary" /> He sends me base64binary and fails every time. All I get is Byte array with only one element inside.

  • Rubygems on Debian: Gems won't load (LoadError)

    - by daswerth
    I've installed the development version of Crunchbang, a linux distro based off Debian. I got Ruby and Rubygems installed, but I can't get the gems I've installed to load. Here is a command-line session: $ ruby -v ruby 1.9.1p378 (2010-01-10 revision 26273) [i486-linux] $ gem env RubyGems Environment: - RUBYGEMS VERSION: 1.3.6 - RUBY VERSION: 1.9.1 (2010-01-10 patchlevel 378) [i486-linux] - INSTALLATION DIRECTORY: /usr/lib/ruby1.9.1/gems/1.9.1 - RUBY EXECUTABLE: /usr/bin/ruby1.9.1 - EXECUTABLE DIRECTORY: /usr/bin - RUBYGEMS PLATFORMS: - ruby - x86-linux - GEM PATHS: - /usr/lib/ruby1.9.1/gems/1.9.1 - /home/corey/.gem/ruby/1.9.1 - GEM CONFIGURATION: - :update_sources => true - :verbose => true - :benchmark => false - :backtrace => false - :bulk_threshold => 1000 - REMOTE SOURCES: - http://rubygems.org/ $ echo $PATH /home/corey/bin:/usr/local/bin:/usr/bin:/bin:/usr/bin/X11:/usr/games:/home/corey/.gem/ruby/1.9.1:/usr/lib/ruby1.9.1/gems/1.9.1 $ gem list -d nokogiri `*** LOCAL GEMS ***` nokogiri (1.4.1) Authors: Aaron Patterson, Mike Dalessio Rubyforge: http://rubyforge.org/projects/nokogiri Homepage: http://nokogiri.org Installed at: /usr/lib/ruby1.9.1/gems/1.9.1 Nokogiri (?) is an HTML, XML, SAX, and Reader parser $ ruby -r rubygems -e "require 'nokogiri'" -e:1:in `require': no such file to load -- nokogiri (LoadError) from -e:1:in `' I've encountered similar problems on Ubuntu before, but they were easy to fix.

I hope this question is relevant. :)

  • php file path of server

    - by Jacksta
    I am trying to get this script to work. it opens up a directry and lists the files in the directory. I have copied this code from somewhere else and the problem is that this php file is hosted on an apache server not my localhost. what is the correct $dir_name = "c:/"; to use? The file is in this directory /domains/domainxxxx.com.au/public_html/lsitfiles.php so would I use domainxxxx.com.au/public_html/lsitfiles.php ? <?php $dir_name = "c:/"; $dir = opendir($dir_name); $file_list = "<ul>"; while ($file_name = readdir($dir)) { if(($file_name != ".") && (file_name != "..")) { $file_list .= "<li>$file_name"; } } $file_list.= "<ul>"; closedir($dir); ?> <HTML> <BODY> <p>Files in: <? echo "$dir_name"; ?></p> <? echo "$file_list"; ?> </BODY> </HTML>

  • BST insert operation. don't insert a node if a duplicate exists already

    - by jeev
    the following code reads an input array, and constructs a BST from it. if the current arr[i] is a duplicate, of a node in the tree, then arr[i] is discarded. count in the struct node refers to the number of times a number appears in the array. fi refers to the first index of the element found in the array. after the insertion, i am doing a post-order traversal of the tree and printing the data, count and index (in this order). the output i am getting when i run this code is: 0 0 7 0 0 6 thank you for your help. Jeev struct node{ int data; struct node *left; struct node *right; int fi; int count; }; struct node* binSearchTree(int arr[], int size); int setdata(struct node**node, int data, int index); void insert(int data, struct node **root, int index); void sortOnCount(struct node* root); void main(){ int arr[] = {2,5,2,8,5,6,8,8}; int size = sizeof(arr)/sizeof(arr[0]); struct node* temp = binSearchTree(arr, size); sortOnCount(temp); } struct node* binSearchTree(int arr[], int size){ struct node* root = (struct node*)malloc(sizeof(struct node)); if(!setdata(&root, arr[0], 0)) fprintf(stderr, "root couldn't be initialized"); int i = 1; for(;i<size;i++){ insert(arr[i], &root, i); } return root; } int setdata(struct node** nod, int data, int index){ if(*nod!=NULL){ (*nod)->fi = index; (*nod)->left = NULL; (*nod)->right = NULL; return 1; } return 0; } void insert(int data, struct node **root, int index){ struct node* new = (struct node*)malloc(sizeof(struct node)); setdata(&new, data, index); struct node** temp = root; while(1){ if(data<=(*temp)->data){ if((*temp)->left!=NULL) *temp=(*temp)->left; else{ (*temp)->left = new; break; } } else if(data>(*temp)->data){ if((*temp)->right!=NULL) *temp=(*temp)->right; else{ (*temp)->right = new; break; } } else{ (*temp)->count++; free(new); break; } } } void sortOnCount(struct node* root){ if(root!=NULL){ sortOnCount(root->left); sortOnCount(root->right); printf("%d %d %d\n", (root)->data, (root)->count, (root)->fi); } }

  • Unable to access Java-created file -- sometimes

    - by BlairHippo
    In Java, I'm working with code running under WinXP that creates a file like this: public synchronized void store(Properties props, byte[] data) { try { File file = filenameBasedOnProperties(props); if ( file.exists() ) { return; } File temp = File.createTempFile("tempfile", null); FileOutputStream out = new FileOutputStream(temp); out.write(data); out.flush(); out.close(); file.getParentFile().mkdirs(); temp.renameTo(file); } catch (IOException ex) { // Complain and whine and stuff } } Sometimes, when a file is created this way, it's just about totally inaccessible from outside the code (though the code responsible for opening and reading the file has no problem), even when the application isn't running. When accessed via Windows Explorer, I can't move, rename, delete, or even open the file. Under Cygwin, I get the following when I ls -l the directory: ls: cannot access [big-honkin-filename] total 0 ?????????? ? ? ? ? ? [big-honkin-filename] As implied, the filenames are big, but under the 260-character max for XP (though they are slightly over 200 characters). To further add to the sense the my computer just wants me to feel stupid, sometimes the files created by this code are perfectly normal. The only pattern I've spotted is that once one file in the directory "locks", the rest are screwed. Anybody ever run into something like this before, or have any insights into what's going on here?

  • When I try to run vim in command line I get Python errors

    - by Eduan
    When I try running vim in the Terminal (so as to follow @romainl's suggestion in my other question) I get lots of Python errors, which all boil down to: IOError: invalid Python installation: unable to open /usr/include/python2.7/pyconfig.h (No such file or directory) Why is this? I can use Python or Sublime Text even, without any problems. The full list of errors is the following: Traceback (most recent call last): File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site.py", line 565, in <module> File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site.py", line 547, in main File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site.py", line 278, in addusersitepackages File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site.py", line 253, in getusersitepackages File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site.py", line 243, in getuserbase File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/sysconfig.py", line 523, in get_config_var File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/sysconfig.py", line 419, in get_config_vars File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/sysconfig.py", line 298, in _init_posix IOError: invalid Python installation: unable to open /usr/include/python2.7/pyconfig.h (No such file or directory) Extra info: I am on Mac OS X Mountain Lion (OS 10.8) EDIT: I tried @BobDunakey idea with no success, the idea was to use sudo.

  • How can I build the Boost.Python example on Ubuntu 9.10?

    - by Gatlin
    I am using Ubuntu 9.10 beta, whose repositories contain boost 1.38. I would like to build the hello-world example. I followed the instructions here (http://www.boost.org/doc/libs/1%5F40%5F0/libs/python/doc/tutorial/doc/html/python/hello.html), found the example project, and issued the "bjam" command. I have installed bjam and boost-build. I get the following output: Jamroot:18: in modules.load rule python-extension unknown in module Jamfile</usr/share/doc/libboost1.38-doc/examples/libs/python/example>. /usr/share/boost-build/build/project.jam:312: in load-jamfile /usr/share/boost-build/build/project.jam:68: in load /usr/share/boost-build/build/project.jam:170: in project.find /usr/share/boost-build/build-system.jam:248: in load /usr/share/boost-build/kernel/modules.jam:261: in import /usr/share/boost-build/kernel/bootstrap.jam:132: in boost-build /usr/share/doc/libboost1.38-doc/examples/libs/python/example/boost-build.jam:7: in module scope I do not know enough about Boost (this is an exploratory exercise for myself) to understand why the python-extension macro in the included Jamroot is not valid. I am running this example from the install directory, so I have not altered the Jamroot's use-project setting. As a side question, if I were to just willy-nilly start a project in an arbitrary directory, how would I write my jamroot?

  • java.io.FileNotFoundException (Permission denied) When trying to write to the Android sdcard

    - by joefischer1
    I am trying to select an image file from the photo gallery and write to the sdcard. Below is the code that results in an exception. It appears to throw this exception when trying to create the FileOutputStream. I have the following line added to the manifest file nested inside the application element.

  • Django Image Upload: IOErrno2 Could not find path -- and yet it's saving the image there anyway?

    - by Rob
    I have an issue where the local version of django is handling image upload as expected but my server is not. Note: I am using a Django Container on MediaTemple.net (grid server) Here is my code. def view_settings(request): <snip> if request.POST: success_msgs = () mForm = MainProfileForm(request.POST, request.FILES, instance = mProfile) pForm = ChangePasswordForm(request.POST) eForm = ChangeEmailForm(request.POST) if mForm.is_valid(): m = mForm.save(commit = False) if mForm.cleaned_data['avatar']: m.avatar = upload_photo(request.FILES['avatar'], settings.AVATAR_SAVE_LOCATION) m.save() success_msgs += ('profile pictured updated',) <snip> def upload_photo(data,saveLocation): savePath = os.path.join(settings.MEDIA_ROOT, saveLocation, data.name) destination = open(savePath, 'wb+') for chunk in data.chunks(): destination.write(chunk) destination.close() return os.path.join(saveLocation, data.name) Here's where it gets whacky and I was hoping someone could shed a light on this error, because either a) it's the wrong error code, or b) something is happening with the file before it's completely handled. To recap, the file was actually uploaded to the server in the intended directory - and yet this err msg continues to persist. IOError at /user/settings [Errno 2] No such file or directory: u'/home/user66666/domains/example.com/html/media/images/avatars/DSC03852.JPG' Environment: Request Method: POST Request URL: http://111.111.111.111:2011/user/settings Django Version: 1.0.2 final Python Version: 2.4.4 Installed Applications: ['django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.sites', 'ctrlme', 'usertools', 'easy_thumbnails'] Installed Middleware: ('django.middleware.common.CommonMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware') Traceback: File "/home/user6666/containers/django/leonidas/usertools/views.py" in view_settings m.avatar = upload_photo(request.FILES['avatar'], settings.AVATAR_SAVE_LOCATION) File "/home/user666666/containers/django/leonidas/usertools/functions.py" in upload_photo destination = open(savePath, 'wb+')

  • getting expat to use .dtd for entity replacement in python

    - by nicolas78
    I'm trying to read in an xml file which looks like this <?xml version="1.0" encoding="ISO-8859-1"?> <!DOCTYPE dblp SYSTEM "dblp.dtd"> <dblp> <incollection> <author>Jos&eacute; A. Blakeley</author> </incollection> </dblp> The point that creates the problem looks is the Jos&eacute; A. Blakeley part: The parser calls its character handler twice, once with "Jos", once with " A. Blakeley". Now I understand this may be the correct behaviour if it doesn't know the eacute entity. However, this is defined in the dblp.dtd, which I have. I don't seem to be able to convince expat to use this file, though. All I can say is p = xml.parsers.expat.ParserCreate() # tried with and without following line p.SetParamEntityParsing(xml.parsers.expat.XML_PARAM_ENTITY_PARSING_ALWAYS) p.UseForeignDTD(True) f = open(dblp_file, "r") p.ParseFile(f) but expat still doesn't recognize my entity. Why is there no way to tell expat which DTD to use? I've tried putting the file into the same directory as the XML putting the file into the program's working directory replacing the reference in the xml file by an absolute path What am I missing? Thx.

  • Network Authentication when running exe from WMI

    - by Andy
    Hi, I have a C# exe that needs to be run using WMI and access a network share. However, when I access the share I get an UnauthorizedAccessException. If I run the exe directly the share is accessible. I am using the same user account in both cases. There are two parts to my application, a GUI client that runs on a local PC and a backend process that runs on a remote PC. When the client needs to connect to the backend it first launches the remote process using WMI (code reproduced below). The remote process does a number of things including accessing a network share using Directory.GetDirectories() and reports back to the client. When the remote process is launched automatically by the client using WMI, it cannot access the network share. However, if I connect to the remote machine using Remote Desktop and manually launch the backend process, access to the network share succeeds. The user specifed in the WMI call and the user logged in for the Remote Desktop session are the same, so the permissions should be the same, shouldn't they? I see in the MSDN entry for Directory.Exists() it states "The Exists method does not perform network authentication. If you query an existing network share without being pre-authenticated, the Exists method will return false." I assume this is related? How can I ensure the user is authenticated correctly in a WMI session? ConnectionOptions opts = new ConnectionOptions(); opts.Username = username; opts.Password = password; ManagementPath path = new ManagementPath(string.Format("\\\\{0}\\root\\cimv2:Win32_Process", remoteHost)); ManagementScope scope = new ManagementScope(path, opts); scope.Connect(); ObjectGetOptions getOpts = new ObjectGetOptions(); using (ManagementClass mngClass = new ManagementClass(scope, path, getOpts)) { ManagementBaseObject inParams = mngClass.GetMethodParameters("Create"); inParams["CommandLine"] = commandLine; ManagementBaseObject outParams = mngClass.InvokeMethod("Create", inParams, null); }

  • Include error in writing html file from php

    - by Grozav Alex Ioan
    I seem to have some problem with my code here. It creates a file from the php file, but I get an error on the include path. include('../include/config.php'); $name = ($_GET['createname']) ? $_GET['createname'] : $_POST['createname']; function buildhtml($strphpfile, $strhtmlfile) { ob_start(); include($strphpfile); $data = ob_get_contents(); $fp = fopen ($strhtmlfile, "w"); fwrite($fp, $data); fclose($fp); ob_end_clean(); } buildhtml('portfolio.php?name='.$name, "../gallery/".$name.".html"); The problem seems to be here: 'portfolio.php?name='.$name Any way I can replace this, and still send the variable over?

  • Visual Studio 2008 Web Project problem with PNG files

    - by NoCarrier
    I've added a PNG file to a directory in my VS2k8 webforms project, and when I run the app, it refuses to render my image - it even knows the dimensions but renders a box with a red X. Oddly enough, if I double click the PNG file within VS2k8, it opens up in the IDE and displays fine (but only within the IDE). Does anyone have any clues? The path is correct.. I just have a basic default.aspx page with this in the body <img src="img/logo.png" /> if i navigate to img/logo.png in the browser, it shows a box with the same dimensions as my image, but a red x. Its finding the image, just not rendering it. It's showing up in IE running under the vs2k8 web server (localhost:5512/default.aspx) I've dropped a JPG in the same directory, and it shows up just fine. I'm not sure what type of PNG it is, but here is the kicker.... If i make an HTML file that references that image, copy both this HTML file and PNG file to my webserver (or just double click on the HTML page), it comes up JUST FINE. Its leading me to believe that the Visual Studio web server may not recognize PNG files (at least this one) properly?

  • Authentication Error when accessing Sharepoint list via web service

    - by Joe
    I wrote a windows service a few months ago that would ping a Sharepoint list using _vti_bin/lists.asmx function GetListItemChanges. It was working fine until a few weeks ago when my company upgraded our Sharepoint instance to SP1. Now whenever my service attempts to access Sharepoint I receive an 401.1 authentication error: Error: You are not authorized to view this page You do not have permission to view this directory or page using the credentials that you supplied. Please try the following: Contact the Web site administrator if you believe you should be able to view this directory or page. HTTP Error 401.1 - Unauthorized: Access is denied due to invalid credentials. Internet Information Services (IIS) I have checked and my privileges on the site have not changed. here is the code In which I call the list: Lists listsService = new Lists(); listsService.Credentials = new NetworkCredential("UserName", "Password", "domain"); Result = listsService.GetListItemChanges("List name", null, dTime.ToString(), null); It has also been brought to my attention that basic authentication may have been disabled on our farm. I don't believe I'm using that but I may be mistaken.

  • Unwanted Shell expansion when assigning the output of a shell command to a variable

    - by Rob Goodwin
    I am exporting a portion of a local prototypte svn repository to import into a different repo. We have a number of svn properties set throughout the repo so I figured I would write a script to list the file elements and their corresponding properties. How hard can that be right. So I write started writing a bash script that would assign the output of the svn proplist -v to a variable so I could check if the specified file had any properties. #!/bin/bash svn proplist -v $1 o=$(svn proplist -v "$1") echo $o now this works fine and echos the output of the svn proplist command. But if the proplist command returns something like svn:ignore : * build it performs a shell expansion on the * and inserts the entire directory listing prior to the build property value. So if the directory had a.txt, b.txt and build files/dirs in it, the output would look like. svn:ignore a.txt b.txt build I figure I need to somehow escape the output or something to keep the expansion from happening, but have yet to find something that works. There are other ways to do this, but I hate when I cannot figure something out. and I have to admin, I think this one beat me ( well given the time I can spend on it )

  • Sql Server Backup and move backup file: How to cope with file permissions?

    - by Stefan Steinegger
    With our product we have a simple backup tool for the sql server database. This tool should just make a full backup and restore to and from any folder. Of course, the user (usually an administrator) needs permission to write to the target folder. To avoid the problem of not being able to perform a backup to a network drive, I write the backup to a temp file in the Sql Server backup directory. Then I move it to the target folder. This requires permission to delete the temporary file from the sql servers backup folder. Restore is the same in the other direction. This seemed to work fine until someone tested it on vista, where the user does not have write access to the backup folder by default. So there are many solutions to solve this, but none of them seemed to be really nice. One solution would be to find another folder for the temporary file. Both the sql server user as well as the administrator performing the backup need read and write permissions. Is there such a directory? Any other ideas? Thanks a lot.

  • How to implement web cache: internal fragmentation VS external fragmentation

    - by Summer_More_More_Tea
    Hi there: I come up with this question when play with Firefox web cache: in which approach does the browser cache a response in limited disk space(take my configuration as an example, 50MB is the upper bound)? I think two ways can be employed. One is cache the total response object one by one, but this is inefficient and will introduce external fragmentation, thus the total cache space may not be fully used. The second is take the total space(50MB) as a consecutive file, splitting it into fixed-length slots; incoming response objects will also be treated blocks of data with the same length as the slots. We can fill slots until the whole file is run out of, then some displacement algorithm can be used to swap out the old cached objects. The latter approach will of course bing in internal fragmentation, but in my opinion is easier to implement and maintain than the first strategy. But when I enter Firefox's Cache directory, I find it (maybe) use a different method: a lot of varied-length files reside in that directory and all those files are filled with undisplayable characters. I don't but really want to know what mechanism that a commercial browser, e.g. Firefoix, employed to implement web cache. Regards.

Apache acts as a "front gate" for all requests and sends them to JBoss via mod_jk. Everything was working fine until I had to do some SEO optimizations. These optimizations include SEF urls, so i decided to use mod_rewrite for Apache to alter requests before they are sent to JBoss. Basically, I nedd to implement 2 rules: Redirect old rules like "http://hostname/directory/" to "http://hostname/" with permanent redirect Forward urls like "http://hostname/wtf/123/" to "http://hostname/wtf/view.htm?id=123" so that end user doesn't see the "ugly" URL (the actual rewrite). Here is my Apache config for test virtual host: <VirtualHost *:80> ServerAdmin [email protected] DocumentRoot "/usr/local/www/dummy" ServerName 192.168.1.10 <IfModule mod_rewrite.c> RewriteEngine On RewriteRule /directory/(.*) /$1 [R=permanent,L] RewriteRule ^/([^/]+)/([0-9]+)/?$ /$1/view.htm?id=$2 </IfModule> JkMount /* jsp-hostname ErrorLog "/var/log/dummy-host.example.com-error_log" CustomLog "/var/log/dummy-host.example.com-access_log" common </VirtualHost> The problem is that second rewrite rule doesn't work. Requests slip through to JBoss unchanged, so I get Tomcat 404 error. But if I add redirect flag to the second rule like RewriteRule ^/([^/]+)/([0-9]+)/?$ /$1/view.htm?id=$2 [R,L] it works like a charm. But redirect is not what I need here :) . I suspect that the problem is that requests are forwarded to the another host (192.168.1.2), but I really don't have any idea on how to make it work. Any help would be appreciated :)

  • Attachment_fu file saving problem

    - by Anand
    Attachment_fu plugin is kind of old, but I have to modify an old app and I can't use another plugin like paperclip etc. So here's the code without further ado Submissions table structure --------------------------- | content_type | varchar(255) | YES | | NULL | filename | varchar(255) | YES | | NULL app/models/submission.rb ------------------------ has_attachment :storage => :file_system, :path_prefix => 'public/submissions', :max_size => 2.megabytes, :content_type => ['application/pdf', 'application/msword', 'text/plain'] app/models/user.rb ------------------ has_one :submission, :dependent => :destroy app/views/user/some_action.html.erb ----------------------------------- <% form_for :user, :url => { :action => "some_action" }, :html => {:multipart => true} do |f| %> .... <%= file_field_tag "submission[uploaded_data]" %> <%end%> app/controllers/user_controller.rb ---------------------------------- @user = User.find_user(session[:user_id]) @submission = @user.submission if request.post? @submission.uploaded_data = params[:submission][:uploaded_data] end When the form is submitted, the database fields "content_type" and "filename" get updated and display the correct values, but the file does not appear in public/submissions/ directory. I have checked the permissions on the submissions directory. What am I missing? Many Thanks

  • Passing options in autospec with Cucumber in Ruby on Rails Development

    - by TK
    I always run autospec to run features and RSpec at the same time, but running all the features is often time-consuming on my local computer. I would run every feature before committing code. I would like to pass the argument in autospec command. autospec doesn't obviously doesn't accept the arguments directly. Here's the output of autospec -h: autotest [options] options: -h -help You're looking at it. -v Be verbose. Prints files that autotest doesn't know how to map to tests. -q Be more quiet. -f Fast start. Doesn't initially run tests at start. I do have a cucumber.yml in config directory. I also have rerun.txt in the Rails root directory. cucumber -h gives me a lot of information about arguments. How can I run autospec against features that are tagged as @wip? I think I can make use of config/cucumber.yml. There are profile definitions. I can run cucumber -p wip to run only @wip-tagged features, but I'd like to do this with autospec. I would appreciate any tips for working with many spec and feature files.

  • TeamCity output artifacts not published to IIS7 folder

    - by clausas
    I am trying to set up TeamCity to build and deploy an ASP.NET MVC application. I have the setup running successfully on other servers using TeamCity 4.5, but the new server is running TeamCity 6, and I am having trouble getting it to work as expected. TeamCity manages to get the files from source control, and the project (Visual Studio Solution 2008 set to "Build") builds and outputs the necessary files as expected. The problem seems to be with my artifact paths, as the output files are not copied to the website folder. My solution consists of dozen projects, of which the "Web" project is the interesting one in this case. The build checkout directory is C:\TeamCity\buildAgent\work\7da320cebf0ee541, and the "Web"-project is found in C:\TeamCity\buildAgent\work\7da320cebf0ee541\Web I have set up my build configuration with the following artifact paths (relative from checkout directory to the folder containing the website): Web/bin=>../../../../inetpub/wwwroot/staging/bin Web/Content=>../../../../inetpub/wwwroot/staging/Content Web/Views=>../../../../inetpub/wwwroot/staging/Views Web/Media=>../../../../inetpub/wwwroot/staging/Media Web/*.aspx=>../../../../inetpub/wwwroot/staging Web/*.asax=>../../../../inetpub/wwwroot/staging (I've tried with more ../ just in case, but it didn't make a difference). This is the output I get from the log [19:35:29]: Publishing artifacts (1s) [19:35:29]: [Publishing artifacts] Paths to publish: [Web/bin=../../../../inetpub/wwwroot/staging/bin, Web/Content=../../../../inetpub/wwwroot/staging/Content, Web/obj=../../../../inetpub/wwwroot/staging/obj, Web/Views=../../../../inetpub/wwwroot/staging/Views, Web/Media=../../../../inetpub/wwwroot/staging/Media, Web/.aspx=../../../../inetpub/wwwroot/staging, Web/.asax=../../../../inetpub/wwwroot/staging, teamcity-info.xml] [19:35:30]: [Publishing artifacts] Sending files [19:35:32]: Build finished Logs from some of the other servers running TeamCity 4.5 uses a different format, with a line for each of the artifacts being published, I'm not sure if this is relevant or only due to a different logging format. Everything seems to be working, but no files are put in my website folder after a build, am I missing something here? Any help will be much appreciated :)

  • PHP import functions

    - by ninuhadida
    Hi, I'm trying to find the best pragmatic approach to import functions on the fly... let me explain. Say I have a directory called functions which has these files: array_select.func.php stat_mediam.func.php stat_mean.func.php ..... I would like to: load each individual file (which has a function defined inside) and use it just like an internal php function.. such as array_pop(), array_shift(), etc. Once I stumbled on a tutorial (which I can't find again now) that compiled user defined functions as part of a PHP installation.. Although that's not a very good solution because on shared/reseller hosting you can't recompile the PHP installation. I don't want to have conflicts with future versions of PHP / other extensions, i.e. if a function named X by me, is suddenly part of the internal php functions (even though it might not have the same functionality per se) I don't want PHP to throw a fatal error because of this and fail miserably. So the best method that I can think of is to check if a function is defined, using function_exists(), if so throw a notice so that it's easy to track in the log files, otherwise define the function. However that will probably translate to having a lot of include/require statement in other files where I need such a function, which I don't really like. Or possibly, read the directory and loop over each *.func.php file and include_once. Though I find this a bit ugly. The question is, have you ever stumbled upon some source code which handled such a case? How was it implemented? Did you ever do something similar? I need as much ideas as possible! :)
