• local user cannot access vsftpd server

  - by Zloy Smiertniy

  I'm currently running a vsftpd server and I added the necessary configurations in vsftpd.conf so that local users can use clients like FileZilla to manage their homes in a server. I found out that only users in the sudoers list access without a problem only they can't download the files, but users that are not sudoers cannot even access their homes from a client but they can access by a web browser using the FTP protocol and they can only access their home directories (as intented) Im running a fedora 14 on my server and my vsftpd.conf looks like this: # Example config file /etc/vsftpd/vsftpd.conf # # The default compiled in settings are fairly paranoid.

• DDNS Not Creating Journal (Dhcpd and Named)

  - by user130094

  * EDIT 1 * After monkeying with additional debug logging I see some log entries of interest. 27-Jul-2012 23:45:26.537 general: error: zone example.lan/IN/internal: journal rollforward failed: no more 27-Jul-2012 23:45:26.537 general: error: zone example.lan/IN/internal: not loaded due to errors. ^^^ If I can remedy the above messages I think I'll be good to go ^^^ * EDIT 2 * Grasping at straws I touched a forward and a reverse zone journal file and restarted named. Boom! Works. Despite documentation stating the files are created automatically and what I have seen before... dunno why but that did the trick. Also re-checked perms on the dir the files live in. As certain as I was, they were correct with named having rw. CentOS 6 (final) dhcpd 4.1.1-P1 named BIND 9.8.2rc1-RedHat-9.8.2-0.10.rc1.el6 Basic DHCP and DNS functionality are in place on 192.168.111.2. Clients are assigned addresses as intended and can resolve local DNS names as well as Internet names. My problem is that named's zone journal files are not created. chroot: /var/named/chroot I tried placing the zone files in various directories (/var/named/data, /var/named, /var/named/dynamic - no matter which dir with named owning and wide open perms I now get nowhere). Along the way I, at one point, got a permission denied when named tried to create the journal. Resolved the issue by: chown --recursive named:named /var/named chmod --recursive 777 /var/named The journal was then created and here's where things fell apart. I attempted to tame permissions to something more sane and broke it. Once changed and having restarted named it threw an error indicating the journal was out of sync (or something to that affect)... didn't matter since this is a new setup so I deleted it and now it is not recreated. Now though I see no errors in /var/log/messages, my chrooted /var/log/named.log, or chrooted /var/log/named.debug. I increased the debug level with 'rndc trace' - no love. Increased trace to 10, still nothing. SELinux is disabled...

• WCF MustUnderstand headers are not understood

  - by raghur

  Hello everyone, I am using a Java Web Service which is developed by one of our vendor which I really do not have any control over it. I have written a WCF router which the client application calls it and the router sends the message to the Java Web Service and returns the data back to the client. The issue what I am encountering is, I am successfully able to call the Java web service from the WCF router, but, I am getting the following exceptions back. Router config file is as follows: <customBinding> <binding name="SimpleWSPortBinding"> <!--<reliableSession maxPendingChannels="4" maxRetryCount="8" ordered="true" />--> <!--<mtomMessageEncoding messageVersion ="Soap12WSAddressing10" ></mtomMessageEncoding>--> <textMessageEncoding maxReadPoolSize="64" maxWritePoolSize="16" messageVersion="Soap12WSAddressing10" writeEncoding="utf-8" /> <httpTransport manualAddressing="false" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" allowCookies="false" authenticationScheme="Anonymous" bypassProxyOnLocal="true" keepAliveEnabled="true" maxBufferSize="65536" transferMode="Buffered" unsafeConnectionNtlmAuthentication="false"/> </binding> </customBinding> Test client config file <customBinding> <binding name="DocumentRepository_Binding_Soap12"> <!--<reliableSession maxPendingChannels="4" maxRetryCount="8" ordered="true" />--> <!--<mtomMessageEncoding messageVersion ="Soap12WSAddressing10" ></mtomMessageEncoding>--> <textMessageEncoding maxReadPoolSize="64" maxWritePoolSize="16" messageVersion="Soap12WSAddressing10" writeEncoding="utf-8"> <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /> </textMessageEncoding> <httpTransport manualAddressing="false" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" allowCookies="false" authenticationScheme="Anonymous" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" keepAliveEnabled="true" maxBufferSize="65536" proxyAuthenticationScheme="Anonymous" realm="" transferMode="Buffered" unsafeConnectionNtlmAuthentication="false" useDefaultWebProxy="true" /> </binding> </customBinding> If I use the textMessageEncoding I am getting <soap:Text xml:lang="en">MustUnderstand headers: [{http://www.w3.org/2005/08/addressing}To, {http://www.w3.org/2005/08/addressing}Action] are not understood.</soap:Text> If I use mtomMessageEncoding I am getting The server did not provide a meaningful reply; this might be caused by a contract mismatch, a premature session shutdown or an internal server error.

Thanks in advance, Raghu

• AuthSub token from Google/YouTube API is always returned as invalid

  - by Miriam Raphael Roberts

  Anyone out there have experience with the YouTube/Google API? I am trying to login to Google/Youtube using clientLogin, retrieve an AuthSub token, exchange it for a multi-session token and then use it in our upload form. Just a note that we are not going to have other users logging into our (secure) website, this is for our use only (no multi-users). We just want a way to upload videos to our YT account via our own website without having to login/upload to YouTube. Ultimately, everything is dependent on the first step. My AuthSub token is always being returned as invalid (Error '403'). All the steps I used are below with username/password changed. Anyone have an insight on why my AuthSub is always invalid? I am spending an enormous amount of time trying to get this to work. STEP 1: Getting the authsub token from Youtube/Google POST /youtube/accounts/ClientLogin HTTP/1.1 User-Agent: curl/7.10.6 (i386-redhat-linux-gnu) libcurl/7.10.6 OpenSSL/0.9.7a ipv6 zlib/1.1.4 Host: www.google.com Pragma: no-cache Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, */* Content-Type:application/x-www-form-urlencoded Content-Length: 86 Email=MyGoogleUsername&Passwd=MyGooglePasswd&accountType=GOOGLE&service=youtube&source=Test RESPONSE RECEIVED: Auth=AIwbFAR99f3iACfkT-5PXCB-1tN4vlyP_1CiNZ8JOn6P-......yv4d4zeGRemNm4il1e-M6czgfDXAR0w9fQ YouTubeUser=MyYouTubeUsername CURL COMMAND USED: /usr/bin/curl -S -v --location https://www.google.com/youtube/accounts/ClientLogin --data Email=MyGoogleUsername&Passwd=MyGooglePasswd&accountType=GOOGLE&service=youtube&source=Test --header Content-Type:application/x-www-form-urlencoded STEP 2: Exchanging the AuthSub token for a multi-use token GET /accounts/AuthSubSessionToken HTTP/1.1 User-Agent: curl/7.10.6 (i386-redhat-linux-gnu) libcurl/7.10.6 OpenSSL/0.9.7a ipv6 zlib/1.1.4 Host: www.google.com Pragma: no-cache Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, */* Content-Type:application/x-www-form-urlencoded Authorization: AuthSub token="AIwbFASiRR3XDKs......p5Oy_VA_9U2yV1enxJoVGSgMlZqTcjKw9mS861vlc9GWTH9D9sQ" Response received: 403 Invalid AuthSub token. curl command used: /usr/bin/curl -S -v --location https://www.google.com/accounts/AuthSubSessionToken --header Content-Type:application/x-www-form-urlencoded -H Authorization: AuthSub token="AIwbFAQR_4xG2g.....vp3BQZW5XEMyIj_wFozHSTEQ-BQRfYuIY-1CyqLeQ" STEP 3: Checking to see if the token is good/valid GET /accounts/AuthSubTokenInfo HTTP/1.1 User-Agent: curl/7.10.6 (i386-redhat-linux-gnu) libcurl/7.10.6 OpenSSL/0.9.7a ipv6 zlib/1.1.4 Host: www.google.com Pragma: no-cache Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, */* Content-Type:application/x-www-form-urlencoded Authorization: AuthSub token="AIwbFASiRR3XDKsNkaIoPaujN5RQhKs3u.....A_9U2yV1enxJoVGSgMlZqTcjKw9mS861vlc9GWTH9D9sQ" Received response: 403 Invalid AuthSub token. curl command used: /usr/bin/curl -S -v --location https://www.google.com/accounts/AuthSubTokenInfo --header Content-Type:application/x-www-form-urlencoded -H Authorization: AuthSub token="AIwbFAQR_4xG2gHoAKDsNdFqdZdwWjGeNquOLpvp3BQZW5XEMyIj_wFozHSTEQ-BQRfYuIY-1CyqLeQ" STEP 4: Trying to get the upload token using the authsub token POST /action/GetUploadToken HTTP/1.1 User-Agent: curl/7.10.6 (i386-redhat-linux-gnu) libcurl/7.10.6 OpenSSL/0.9.7a ipv6 zlib/1.1.4 Host: gdata.youtube.com Pragma: no-cache Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, */* Content-Type:application/atom+xml Authorization: AuthSub token="AIwbFASiRR3XDKsNkaIoPaujN5RQhp5Oy_VA_9U2yV1enxJoVGSgMlZqTcjKw9mS861vlc9GWTH9D9sQ" X-Gdata-Key:key="AI39si5EQyo-TZPFAnmGjxJGFKpxd_7a6hEERh_3......R82AShoQ" Content-Length:0 GData-Version:2 Recevied Response: 401 Token invalid - Invalid AuthSub token.

• WCF contract mismatch problem

  - by Tom

  Hi there, I have a client console app talking to a WCF service and I get the following error: "The server did not provide a meaningful reply; this might be caused by a contract mismatch, a premature session shutdown or an internal server error." I think it's becuase of a contract mismatch but i can't figure out why. The service runs just fine by itself and the 2 parts were working together until i added the impersonation code. Can anyone see what is wrong? Here is the client, all done in code: NetTcpBinding binding = new NetTcpBinding(); binding.Security.Mode = SecurityMode.Message; binding.Security.Message.ClientCredentialType = MessageCredentialType.Windows; EndpointAddress endPoint = new EndpointAddress(new Uri("net.tcp://serverName:9990/TestService1")); ChannelFactory<IService1> channel = new ChannelFactory<IService1>(binding, endPoint); channel.Credentials.Windows.AllowedImpersonationLevel = TokenImpersonationLevel.Impersonation; IService1 service = channel.CreateChannel(); And here is the config file of the WCF service: <configuration> <system.serviceModel> <bindings> <netTcpBinding> <binding name="MyBinding"> <security mode="Message"> <transport clientCredentialType="Windows"/> <message clientCredentialType="Windows" /> </security> </binding> </netTcpBinding> </bindings> <behaviors> <serviceBehaviors> <behavior name="WCFTest.ConsoleHost2.Service1Behavior"> <serviceMetadata httpGetEnabled="true" /> <serviceDebug includeExceptionDetailInFaults="true" /> <serviceAuthorization impersonateCallerForAllOperations="true" /> </behavior> </serviceBehaviors> </behaviors> <services> <service behaviorConfiguration="WCFTest.ConsoleHost2.Service1Behavior" name="WCFTest.ConsoleHost2.Service1"> <endpoint address="" binding="wsHttpBinding" contract="WCFTest.ConsoleHost2.IService1"> <identity> <dns value="" /> </identity> </endpoint> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> <endpoint binding="netTcpBinding" bindingConfiguration="MyBinding" contract="WCFTest.ConsoleHost2.IService1" /> <host> <baseAddresses> <add baseAddress="http://serverName:9999/TestService1/" /> <add baseAddress="net.tcp://serverName:9990/TestService1/" /> </baseAddresses> </host> </service> </services> </system.serviceModel> </configuration>

• Facebook require_login() in iFrame App

  - by LapKom

  Hi, I have serious problem with iframe application. I need to use many external JS libraries and other dynamic stuuf so FMBL application can't be done. When I call require_login() I get applicaition installing dialog when app is not already installed, which is ok. But then after authorization application enters an endless redirect loop with parameters like auth_token, installed and so. Yesterday I managed to fix this, but today it's broken again... What the heck is happening with FB? It's driving me crazy to find a sollution, none of ones found on net doesn't seem to be working. So far I tried: http://abhirama.wordpress.com/2010/03/07/facebook-iframe-xfbml-app/ (7th march 2010!) http://forum.developers.facebook.com/viewtopic.php?pid=156092 http://www.keywordintellect.com/facebook-development/how-to-set-up-a-facebook-iframe-application-in-php-in-5-minutes/ http://www.markdeepwell.com/2010/02/validating-a-facebook-session-within-an-iframe/ http://forum.developers.facebook.com/viewtopic.php?pid=210449 http://www.ajaxlines.com/ajax/stuff/article/facebook_fbml_rendering_in_iframe_application.php http://www.aratide.com/php/solving-the-break-out-issue-in-iframe-facebook-applications/ None of the above worked... According to those and some FB docs: http://wiki.developers.facebook.com/index.php/FB_RequireFeatures http://wiki.developers.facebook.com/index.php/Cross_Domain_Communication_Channel My example test files look as follow: <?php //Link in library. require_once '../application/vendor/Facebook/facebook.php'; //Authentication Keys $appapikey = 'XXXX'; $appsecret = 'XXXX'; //Construct the class $facebook = new Facebook($appapikey, $appsecret); //Require login $user_id = $facebook->require_login(); ?> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:fb="http://www.facebook.com/2008/fbml"> <head> <title></title> </head> <body> <script src="http://static.ak.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php" type="text/javascript"></script> This is you: <fb:name uid="<?php echo $user_id?>"></fb:name> <?php var_dump($facebook->$this->facebook->api_client->friends_get())?> <script type="text/javascript"> FB_RequireFeatures(["XFBML"], function(){ FB.Facebook.init("<?=$appapikey?>", "xd_receiver.html"); }); </script> </body> </html> And cross-domain file xd_receiver.html is: <!doctype html public "-//w3c//dtd xhtml 1.0 strict//en" "http://www.w3.org/tr/xhtml1/dtd/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head> <title>cross-domain receiver page</title> </head> <body> <script src="http://static.ak.facebook.com/js/api_lib/v0.4/XdCommReceiver.js" type="text/javascript"></script> </body> </html> How do I get it working? I'm using Kohana framework to do this and already replaced header('Location') with url::redirect() in facebook php library.

• Delphi 7 SOAP Authentication and SessionID HowTo

  - by Justin Philbrow

  Hello All, I am developing a 3 tier database application. 1.) MS SQL DB 2.) Middle tier SOAP Server (with Delphi 7) connected to the DB 3.) Clients (first win32 gui (with Delphi 7) - later other platfomrs) connected to the SOAP server I chose a SOAP Server to be open to various clients at a later stage (also some of the win32 gui clients will be stationed abroad - so the clients need to be thin) (this as suggested by Dr. Bob). I am new to SOAP and have been looking at different examples and papers about authentication. But cant quite get my head around it. I have made a SOAP server and client with Delphi's SOAP Server Application Wizard and added a SOAP SERVER Data Module, added a database connection and some datasets and providers. Connected the client with dbgrid etc and that part works fine. But I want the client first to login and then be able to access data and I want the server to log each connection and also when the client logs off or is disconnected, so I am guessing I need the sessionID and a timeout. I also want the server to be able to tell the clients who else is "connected" (or whos session is still active) at any given time. I have gathered that I need to make a authentication header, but cant figure out where or who I can get a sessionID. I presume that each time a client connectes to the server the server generates a sessionID? How do I get this? Any help or suggestions/pointer would be appreciated, thanks Justin OK take 2: OK, I have done the following so far (this is used from the example Bank Account SOAP application that comes with Delphi 7): procedure TForm1.btnLoginClick(Sender: TObject); var H: TAuthHeader; Headers: ISOAPHeaders; SoapData: IThorPayServerDB; begin SoapData := HTTPRIOOnForm as IThorPayServerDB; if not(SoapData.login(edtUser.Text,edtPassword.Text)) then begin showmessage('Not correct login'); exit; end; Headers := SoapData as ISoapHeaders; { Get the header from the incoming message } Headers.Get(TAuthHeader, TSoapHeader(H)); try if H < nil then begin FIdKey := H.IdNumber; FTimeStamp := H.TimeStamp; end else ShowMessage('No authentication header received from server'); finally H.Free; end; if FIdKey 0 then showmessage('Authenticated');; end; The SoapData.login returns the correct result, but for some reason I cant get hold of the header. In this case H is nil and the result becomes 'No authentication header received from server'. If I intersept the SOAP xml I can see that the header is there, here is the returned package: 1 1 4208687 2010-05-14T10:03:49.469+03:00 true Anyone any idea? In this case I am not using the SOAPConnetion that I am using for the DB, but a seperate HTTPTRIO component.

• How to return a complex object from an axis web service

  Hi all, I am writing a simple web service to return an object with 2 properties. I am embedding the service into an existing web application.

• Multiple "pages" in GWT with human friendly URLs

  - by Andreas Borglin

  Hi. I'm playing with a GWT/GAE project which will have three different "pages", although it is not really pages in a GWT sense. The top views (one for each page) will have completely different layouts, but some of the widgets will be shared. One of the pages is the main page which is loaded by the default url (http://www.site.com), but the other two needs additional URL information to differentiate the page type. They also need a name parameter, (like http://www.site.com/project/project-name. There are at least two solutions to this that I'm aware of. Use GWT history mechanism and let page type and parameters (such as project name) be part of the history token. Use servlets with url-mapping patterns (like /project/*) The first choice might seem obvious at first, but it has several drawbacks. First, a user should be able to easily remember and type URL directly to a project. It is hard to produce a human friendly URL with history tokens. Second, I'm using gwt-presenter and this approach would mean that we need to support subplaces in one token, which I'd rather avoid. Third, a user will typically stay at one page, so it makes more sense that the page information is part of the "static" URL. Using servlets solves all these problems, but also creates other ones. So my first questions is, what is the best solution here? If I would go for the servlet solution, new questions pop up. It might make sense to split the GWT app into three separate modules, each with an entry point. Each servlet that is mapped to a certain page would then simply forward the request to the GWT module that handles that page. Since a user typically stays at one page, the browser only needs to load the js for that page. Based on what I've read, this solution is not really recommended. I could also stick with one module, but then GWT needs to find out which page it should display. It could either query the server or parse the URL itself. If I stick with one GWT module, I need to keep the page information stored on server side. Naturally I thought about sessions, but I'm not sure if its a good idea to mix page information with user data. A session usually lives between user login and logout, but in this case it would need different behavior. Would it be bad practise to handle this via sessions? The one GWT module + servlet solution also leads to another problem. If a user goes from a project page to the main page, how will GWT know that this has happened? The app will not be reloaded, so it will be treated as a simple state change. It seems rather ineffecient to have to check page info for every state change. Anyone care to guide me out of the foggy darkness that surrounds me? :-)

• Django TemplateSyntaxError only on live server (templates exist)

  - by Tom

  I'm getting a strange error that only occurs on the live server. My Django templates directory is set up like so base.html two-column-base.html portfolio index.html extranet base.html index.html The portfolio pages work correctly locally on multiple machines. They inherit from either the root base.html or two-column-base.html. However, now that I've posted them to the live box (local machines are Windows, live is Linux), I get a TemplateSyntaxError: "Caught TemplateDoesNotExist while rendering: base.html" when I try to load any portfolio pages. It seems to be a case where the extends tag won't work in that root directory (???). Even if I do a direct_to_template on two-column-base.html (which extends base.html), I get that error. The extranet pages all work perfectly, but those templates all live inside the /extranet folder and inherit from /extranet/base.html. Possible issues I've checked: file permissions on the server are fine the template directory is correct on the live box (I'm using os.path.dirname(os.path.realpath(__file__)) to make things work across machines) files exist and the /templates directories exactly match my local copy removing the {% extends %} block from the top of any broken template causes the templates to render without a problem manually starting a shell session and calling get_template on any of the files works, but trying to render it blows up with the same exception on any of the extended templates. Doing the same with base.html, it renders perfectly (base.html also renders via direct_to_template) Django 1.2, Python 2.6 on Webfaction. Apologies in advance because this is my 3rd or 4th "I'm doing something stupid" question in a row. The only x-factor I can think of is this is my first time using Mercurial instead ofsvn. Not sure how I could have messed things up via that. EDIT: One possible source of problems: local machine is Python 2.5, live is 2.6. Here's a traceback of me trying to render 'two-column-base.html', which extends 'base.html'. Both files are in the same directory, so if it can find the first, it can find the second. c is just an empty Context object. >>> render_to_string('two-column-base.html', c) Traceback (most recent call last): File "<console>", line 1, in <module> File "/home/lightfin/webapps/django/lib/python2.6/django/template/loader.py", line 186, in render_to_string return t.render(context_instance) File "/home/lightfin/webapps/django/lib/python2.6/django/template/__init__.py", line 173, in render return self._render(context) File "/home/lightfin/webapps/django/lib/python2.6/django/template/__init__.py", line 167, in _render return self.nodelist.render(context) File "/home/lightfin/webapps/django/lib/python2.6/django/template/__init__.py", line 796, in render bits.append(self.render_node(node, context)) File "/home/lightfin/webapps/django/lib/python2.6/django/template/debug.py", line 72, in render_node result = node.render(context) File "/home/lightfin/webapps/django/lib/python2.6/django/template/loader_tags.py", line 103, in render compiled_parent = self.get_parent(context) File "/home/lightfin/webapps/django/lib/python2.6/django/template/loader_tags.py", line 100, in get_parent return get_template(parent) File "/home/lightfin/webapps/django/lib/python2.6/django/template/loader.py", line 157, in get_template template, origin = find_template(template_name) File "/home/lightfin/webapps/django/lib/python2.6/django/template/loader.py", line 138, in find_template raise TemplateDoesNotExist(name) TemplateSyntaxError: Caught TemplateDoesNotExist while rendering: base.html I'm wondering if this is somehow related to the template caching that was just added to Django. EDIT 2 (per lazerscience): template-related settings: import os PROJECT_ROOT = os.path.dirname(os.path.realpath(__file__)) TEMPLATE_DIRS = ( os.path.join(PROJECT_ROOT, 'templates'), ) sample view: def project_list(request, jobs, extra_context={}): context = { 'jobs': jobs, } print context context.update(extra_context) return render_to_response('portfolio/index.html', context, context_instance=RequestContext(request)) The templates in reverse-order are: http://thosecleverkids.com/junk/index.html http://thosecleverkids.com/junk/portfolio-base.html http://thosecleverkids.com/junk/two-column-base.html http://thosecleverkids.com/junk/base.html though in the real project the first two live in a directory called "portfolio".

• Segfaulting Java process

  - by zenmonkey

  I've a java process that is working on some large data set in memory. I've seen it crash with a SIGSEGV signal sometimes, so i was wondering some potential causes and fixes could do. Caues: - JVM bug - Native library bug (e.g pthreads etc) - JNI bug in user code Fixes: - Upgrade to new JVM In my particular case, this is the output form the log file (pruned) A fatal error has been detected by the Java Runtime Environment: # SIGSEGV (0xb) at pc=0x00002aaaaacd1b94, pid=32116, tid=1086544208 # JRE version: 6.0_14-b08 Java VM: Java HotSpot(TM) 64-Bit Server VM (14.0-b16 mixed mode

• Autocomplete jQuery on User Controller within Repeater .NET

  - by TheDPQ

  I have a Multiview search feature on a Web User Controller that is called within a Repeater, OHMY!! I have some training sessions being listed out on a page, each calling an employeeSearch Web User Controller so people can search for employees to add to the training session. I have the Employee Names and Employee IDs listed out in JS on the page and using the jQuery autocomplete i have them search for the employee and populate a hidden field in the User controller. Once the process is done they have the option of adding yet another employee. So i had Autocompelte 'work' in all the employee search boxes, but one i do the initial search (postback) autocomplete won't work again. Then i updated $().ready(function() to pageLoad() so it works correctly on multiple searches but only in the LAST item of the repeater (jQuery is loaded on the User Controller) FYI: I have the JS string set as EMPLOYEENAME|ID and jQuery displays the Employee Name and if they select it throws the ID in a ASP:HIDDEN FIELD <script type="text/javascript"> format_item = function(item, position, length) { var str = item.toString().split("|", 2); return str[0]; } function pageLoad() { $("#<%=tb_EmployeeName.ClientID %>").autocomplete(EmployeeList, { minChars: 0, width: 500, matchContains: true, autoFill: false, scrollHeight: 300, scroll: true, formatItem: format_item, formatMatch: format_item, formatResult: format_item }); $("#<%=tb_EmployeeName.ClientID %>").result(function(event, data, formatted) { var str = data.toString().split("|", 2); $("#<%=hf_EmployeeID.ClientID %>").val(str[1]); }); }; </script> I can already guess that by repeating pageLoad within the User Controll i override the previous pageLoad. THE QUESTION: Is there a way around this, a way to have all the jQuery appear in a single pageLoad or to somehow have a single jquery call to handle all my search boxes? I can't move the jQuery into the page calling all the controllers because i have no way of referencing the specific *tb_EmployeeName* textbox AND *hf_EmployeeID* hidden field. Thank you so much for any help or insight you can give me into this problem. This is the Multiview that on the User Controller <asp:MultiView ID="mv_EmployeeArea" runat="server" ActiveViewIndex="0"> <asp:View ID="vw_Search" runat="server"> <asp:Panel ID="eSearch" runat="server"> <b>Signup Employee Search</b> (<i>Last Name, First Name</i>)<br /> <asp:TextBox ID="tb_EmployeeName" class="EmployeeSearch" runat="server"></asp:TextBox> <asp:HiddenField ID="hf_EmployeeID" runat="server" /> <asp:Button ID="btn_Search" runat="server" Text="Search" /> </asp:Panel> </asp:View> <asp:View ID="vw_Confirm" runat="server"> <b>Signup Confirmation</b> <asp:FormView ID="fv_EmployeeInfo" runat="server"> <ItemTemplate> <%#(Eval("LastName"))%>, <%#(Eval("FirstName"))%><br /> </ItemTemplate> </asp:FormView> <asp:Button ID="btn_Confirm" runat="server" Text="Signup this employee" /> &nbsp; <asp:Button ID="btn_Reset3" runat="server" Text="Reset" /> </asp:View> <asp:View ID="vw_ThankYou" runat="server"> <b>Thank You</b><br /> The employee has been signed up and an email confirmation has been sent out.<br /><br /> <asp:Button ID="btn_Reset" runat="server" Text="Reset" /> </asp:View> </asp:MultiView> UPDATE: I never did find an answer but i had to do a demo so i hacked together something that 'works', but feels sort of cheesy. I am still very much needed of a better question or better understanding.

My wsdd looks like this. <globalConfiguration> <parameter name="adminPassword" value="admin"/> <parameter name="sendXsiTypes" value="true"/> <parameter name="sendMultiRefs" value="true"/> <parameter name="sendXMLDeclaration" value="true"/> <parameter name="axis.sendMinimizedElements" value="true"/> <requestFlow> <handler type="java:org.apache.axis.handlers.JWSHandler"> <parameter name="scope" value="session"/> </handler> <handler type="java:org.apache.axis.handlers.JWSHandler"> <parameter name="scope" value="request"/> <parameter name="extension" value=".jwr"/> </handler> </requestFlow> </globalConfiguration> <handler name="LocalResponder" type="java:org.apache.axis.transport.local.LocalResponder"/> <handler name="URLMapper" type="java:org.apache.axis.handlers.http.URLMapper"/> <handler name="Authenticate" type="java:org.apache.axis.handlers.SimpleAuthenticationHandler"/> <transport name="http"> <requestFlow> <handler type="URLMapper"/> <handler type="java:org.apache.axis.handlers.http.HTTPAuthHandler"/> </requestFlow> </transport> <transport name="local"> <responseFlow> <handler type="LocalResponder"/> </responseFlow> </transport> <service name="helloService" provider="java:RPC" style="document" use="literal"> <parameter name="className" value="ws.example.HelloService"/> <parameter name="allowedMethods" value="*"/> <parameter name="scope" value="application"/> </service> I am able to deploy it successfully. If I try to invoke the method which returns a String, it is successfully returning the String. But when I invoke the method which returns an object, I am getting the following error. AxisFault faultCode: {http://schemas.xmlsoap.org/soap/envelope/}Server.userException faultSubcode: faultString: org.xml.sax.SAXParseException: Premature end of file. faultActor: faultNode: faultDetail: {http://xml.apache.org/axis/}stackTrace:org.xml.sax.SAXParseException: Premature end of file. at org.apache.xerces.util.ErrorHandlerWrapper.createSAXParseException(Unknown Source) at org.apache.xerces.util.ErrorHandlerWrapper.fatalError(Unknown Source) at org.apache.xerces.impl.XMLErrorReporter.reportError(Unknown Source) at org.apache.xerces.impl.XMLErrorReporter.reportError(Unknown Source) at org.apache.xerces.impl.XMLVersionDetector.determineDocVersion(Unknown Source) at org.apache.xerces.parsers.XML11Configuration.parse(Unknown Source) at org.apache.xerces.parsers.XML11Configuration.parse(Unknown Source) at org.apache.xerces.parsers.XMLParser.parse(Unknown Source) at org.apache.xerces.parsers.AbstractSAXParser.parse(Unknown Source) at org.apache.xerces.jaxp.SAXParserImpl$JAXPSAXParser.parse(Unknown Source) at javax.xml.parsers.SAXParser.parse(SAXParser.java:395) at org.apache.axis.encoding.DeserializationContext.parse(DeserializationContext.java:227) at org.apache.axis.SOAPPart.getAsSOAPEnvelope(SOAPPart.java:696) at org.apache.axis.Message.getSOAPEnvelope(Message.java:424) at org.apache.axis.transport.http.HTTPSender.readFromSocket(HTTPSender.java:796) at org.apache.axis.transport.http.HTTPSender.invoke(HTTPSender.java:144) at org.apache.axis.strategies.InvocationStrategy.visit(InvocationStrategy.java:32) at org.apache.axis.SimpleChain.doVisiting(SimpleChain.java:118) at org.apache.axis.SimpleChain.invoke(SimpleChain.java:83) at org.apache.axis.client.AxisClient.invoke(AxisClient.java:165) at org.apache.axis.client.Call.invokeEngine(Call.java:2765) at org.apache.axis.client.Call.invoke(Call.java:2748) at org.apache.axis.client.Call.invoke(Call.java:2424) at org.apache.axis.client.Call.invoke(Call.java:2347) at org.apache.axis.client.Call.invoke(Call.java:1804) at ws.example.ws.HelloServiceSoapBindingStub.getAwardById(HelloServiceSoapBindingStub.java:202) at Test.main(Test.java:21) Can any body help?

• ASP.NET Send Image Attachment With Email Without Saving To Filesystem

  - by KGO

  I'm trying to create a form that will send an email with an attached image and am running into some problems. The form I am creating is rather large so I have created a small test form for the purpose of this question. The email will send and the attachment will exist on the email, but the image is corrupt or something as it is not viewable. Also.. I do not want to save the image to the filesystem. You may think it is convoluted to take the image file from the fileupload to a stream, but this is due to the fact that the real form I am working on will allow multiple files to be added through a single fileupload and will be saved in session, thus the images will not be coming from the fileupload control directly on submit.

• Servlet/JSP Flow Control: Enums, Exceptions, or Something Else?

  - by Christopher Parker

  I recently inherited an application developed with bare servlets and JSPs (i.e.: no frameworks). I've been tasked with cleaning up the error-handling workflow. Currently, each <form> in the workflow submits to a servlet, and based on the result of the form submission, the servlet does one of two things: If everything is OK, the servlet either forwards or redirects to the next page in the workflow. If there's a problem, such as an invalid username or password, the servlet forwards to a page specific to the problem condition. For example, there are pages such as AccountDisabled.jsp, AccountExpired.jsp, AuthenticationFailed.jsp, SecurityQuestionIncorrect.jsp, etc. I need to redesign this system to centralize how problem conditions are handled. So far, I've considered two possible solutions: Exceptions Create an exception class specific to my needs, such as AuthException. Inherit from this class to be more specific when necessary (e.g.: InvalidUsernameException, InvalidPasswordException, AccountDisabledException, etc.). Whenever there's a problem condition, throw an exception specific to the condition. Catch all exceptions via web.xml and route them to the appropriate page(s) with the <error-page> tag. enums Adopt an error code approach, with an enum keeping track of the error code and description. The descriptions can be read from a resource bundle in the finished product. I'm leaning more toward the enum approach, as an authentication failure isn't really an "exceptional condition" and I don't see any benefit in adding clutter to the server logs. Plus, I'd just be replacing one maintenance headache with another. Instead of separate JSPs to maintain, I'd have separate Exception classes. I'm planning on implementing "error" handling in a servlet that I'm writing specifically for this purpose. I'm also going to eliminate all of the separate error pages, instead setting an error request attribute with the error message to display to the user and forwarding back to the referrer. Each target servlet (Logon, ChangePassword, AnswerProfileQuestions, etc.) would add an error code to the request and redirect to my new servlet in the event of a problem. My new servlet would look something like this: public enum Error { INVALID_PASSWORD(5000, "You have entered an invalid password."), ACCOUNT_DISABLED(5002, "Your account has been disabled."), SESSION_EXPIRED(5003, "Your session has expired. Please log in again."), INVALID_SECURITY_QUESTION(5004, "You have answered a security question incorrectly."); private final int code; private final String description; Error(int code, String description) { this.code = code; this.description = description; } public int getCode() { return code; } public String getDescription() { return description; } }; protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { String sendTo = "UnknownError.jsp"; String message = "An unknown error has occurred."; int errorCode = Integer.parseInt((String)request.getAttribute("errorCode"), 10); Error errors[] = Error.values(); Error error = null; for (int i = 0; error == null && i < errors.length; i++) { if (errors[i].getCode() == errorCode) { error = errors[i]; } } if (error != null) { sendTo = request.getHeader("referer"); message = error.getDescription(); } request.setAttribute("error", message); request.getRequestDispatcher(sendTo).forward(request, response); } protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { doGet(request, response); } Being fairly inexperienced with Java EE (this is my first real exposure to JSPs and servlets), I'm sure there's something I'm missing, or my approach is suboptimal. Am I on the right track, or do I need to rethink my strategy?

• JBoss Seam: In ScopeType.PAGE I get: java.lang.IllegalStateException: No conversation context active

  - by Markos Fragkakis

  Hi all, I have a page-scoped component, which has an instance variable List with data, which I display in a datatable. This datatable has pagination, sorting and filtering. The first time gate into the page, I get this appended in my URL: ?conversationId=97. The page works correctly, and when I change datatable pages no now component is created. After a minute or two, and at seamingly random time, I get an exception saying that there is no context. I have not used @Create in my code or my navigation files. So, I have two questions: Why do I get this suffix in my URL? Why did a conversation start? Why the exception? The component is scoped to PAGE. If I received an exception, it should not be related to a conversation. Right? Or is the conversation the exception is referring a temporary conversation? Cheers!

• jQuery dialog box, php form.

  i have a dialog box that opens on pageload for a site. script type="text/javascript"> $(function() { $('#dialog-message').dialog({ modal: 'true', width: '400' }); }); </script> this pulls up an include: <div id="dialog-message" title="Free Jiu Jitsu Session at Alliance"> <!--#include virtual="/includes/guest.php" --> guest.php has a very small form that is processed by the page itself: <?php $dbh=mysql_connect //login stuff here if (isset($_POST['submit'])) { if (!$_POST['name'] | !$_POST['email']) { echo"<div class='error'>Error<br />Please provide your Name and Email Address so we may properly contact you.</div>"; } else { $age = $_POST['age']; $name = $_POST['name']; $gender = $_POST['gender']; $email = $_POST['email']; $phone = $_POST['phone']; $comments = $_POST['comments']; $query = "INSERT INTO table here (age,name,gender,email,phone,comments) VALUES ('$age','$name','$gender','$email','$phone','$comments')"; mysql_query($query); mysql_close(); $yoursite = "my site here"; $youremail = $email; $subject = "Website Guest Contact Us Form"; $message = "message here"; $email2 = "send to email address"; mail($email2, $subject, $message, "From: $email"); echo"<div class='thankyou'>Thank you for contacting us,<br /> we will respond as soon as we can.</div>"; } } ?> <form id="contact_us" class="guest" method="post" action="/guest.php" > <fieldset> <legend>Personal Info</legend> <label for="name" class="guest">Name:</label> <input type="text" name="name" id="name" value="" /><br> <label for="phone" class="guest">Phone:</label> <input type="text" name="phone" id="phone" value="" /><br> <label for="email" class="guest">Email Address:</label> <input type="text" name="email" id="email" value="" /><br> <label for="age" class="guest">Age:</label> <input type="text" name="age" id="age" value="" size="2" /><br> <label for="gender" class="guest">Sex:</label> <input type="radio" name="gender" value="male" /> Male <input type="radio" name="gender" value="female" /> Female<br /> </fieldset> <fieldset> <legend>Comments</legend> <label for="comments" class="guest">Comments / Questions:</label> <textarea id="comments" name="comments" rows="4" cols="22"></textarea><br> <input type="submit" value="Submit" name="submit" /> <input type="Reset" value="Reset" /> </fieldset> </form> Problem is, that the path of the form action does not work, becasue this dialog box is on the index.html page of the site, and if i put the absolute path, it doesnt process... i have this functioning on another contact us page, so i know it works, but wit the dialog box, it seems to have stumped me... what should i do?

• Running an allocation simulation repeatedly breaks after the first run.

  - by Az

  Background I have a bunch of students, their desired projects and the supervisors for the respective projects. I'm running a battery of simulations to see which projects the students end up with, which will allow me to get some useful statistics required for feedback. So, this is essentially a Monte-Carlo simulation where I'm randomising the list of students and then iterating through it, allocating projects until I hit the end of the list. Then the process is repeated again. Note that, within a single session, after each successful allocation of a project the following take place: + the project is set to allocated and cannot be given to another student + the supervisor has a fixed quota of students he can supervise. This is decremented by 1 + Once the quota hits 0, all the projects from that supervisor become blocked and this has the same effect as a project being allocated Code def resetData(): for student in students.itervalues(): student.allocated_project = None for supervisor in supervisors.itervalues(): supervisor.quota = 0 for project in projects.itervalues(): project.allocated = False project.blocked = False The role of resetData() is to "reset" certain bits of the data. For example, when a project is successfully allocated, project.allocated for that project is flipped to True. While that's useful for a single run, for the next run I need to be deallocated. Above I'm iterating through thee three dictionaries - one each for students, projects and supervisors - where the information is stored. The next bit is the "Monte-Carlo" simulation for the allocation algorithm. sesh_id = 1 for trial in range(50): for id in randomiseStudents(1): stud_id = id student = students[id] if not student.preferences: # Ignoring the students who've not entered any preferences for rank in ranks: temp_proj = random.choice(list(student.preferences[rank])) if not (temp_proj.allocated or temp_proj.blocked): alloc_proj = student.allocated_proj_ref = temp_proj.proj_id alloc_proj_rank = student.allocated_rank = rank successActions(temp_proj) temp_alloc = Allocated(sesh_id, stud_id, alloc_proj, alloc_proj_rank) print temp_alloc # Explained break sesh_id += 1 resetData() # Refer to def resetData() above All randomiseStudents(1) does is randomise the order of students. Allocated is a class defined as such: class Allocated(object): def __init__(self, sesh_id, stud_id, alloc_proj, alloc_proj_rank): self.sesh_id = sesh_id self.stud_id = stud_id self.alloc_proj = alloc_proj self.alloc_proj_rank = alloc_proj_rank def __repr__(self): return str(self) def __str__(self): return "%s - Student: %s (Project: %s - Rank: %s)" %(self.sesh_id, self.stud_id, self.alloc_proj, self.alloc_proj_rank) Output and problem Now if I run this I get an output such as this (truncated): 1 - Student: 7720 (Project: 1100241 - Rank: 1) 1 - Student: 7832 (Project: 1100339 - Rank: 1) 1 - Student: 7743 (Project: 1100359 - Rank: 1) 1 - Student: 7820 (Project: 1100261 - Rank: 2) 1 - Student: 7829 (Project: 1100270 - Rank: 1) . . . 1 - Student: 7822 (Project: 1100280 - Rank: 1) 1 - Student: 7792 (Project: 1100141 - Rank: 7) 2 - Student: 7739 (Project: 1100267 - Rank: 1) 3 - Student: 7806 (Project: 1100272 - Rank: 1) . . . 45 - Student: 7806 (Project: 1100272 - Rank: 1) 46 - Student: 7714 (Project: 1100317 - Rank: 1) 47 - Student: 7930 (Project: 1100343 - Rank: 1) 48 - Student: 7757 (Project: 1100358 - Rank: 1) 49 - Student: 7759 (Project: 1100269 - Rank: 1) 50 - Student: 7778 (Project: 1100301 - Rank: 1) Basically, it works perfectly for the first run, but on subsequent runs leading upto the nth run, in this case 50, only a single student-project allocation pair is returned. Thus, the main issue I'm having trouble with is figuring out what is causing this anomalous behaviour especially since the first run works smoothly. Thanks in advance, Az

• python: what are efficient techniques to deal with deeply nested data in a flexible manner?

  - by AlexandreS

  My question is not about a specific code snippet but more general, so please bear with me: How should I organize the data I'm analyzing, and which tools should I use to manage it? I'm using python and numpy to analyse data. Because the python documentation indicates that dictionaries are very optimized in python, and also due to the fact that the data itself is very structured, I stored it in a deeply nested dictionary. Here is a skeleton of the dictionary: the position in the hierarchy defines the nature of the element, and each new line defines the contents of a key in the precedent level: [AS091209M02] [AS091209M01] [AS090901M06] ... [100113] [100211] [100128] [100121] [R16] [R17] [R03] [R15] [R05] [R04] [R07] ... [1263399103] ... [ImageSize] [FilePath] [Trials] [Depth] [Frames] [Responses] ... [N01] [N04] ... [Sequential] [Randomized] [Ch1] [Ch2] Edit: To explain a bit better my data set: [individual] ex: [AS091209M02] [imaging session (date string)] ex: [100113] [Region imaged] ex: [R16] [timestamp of file] ex [1263399103] [properties of file] ex: [Responses] [regions of interest in image ] ex [N01] [format of data] ex [Sequential] [channel of acquisition: this key indexes an array of values] ex [Ch1] The type of operations I perform is for instance to compute properties of the arrays (listed under Ch1, Ch2), pick up arrays to make a new collection, for instance analyze responses of N01 from region 16 (R16) of a given individual at different time points, etc. This structure works well for me and is very fast, as promised. I can analyze the full data set pretty quickly (and the dictionary is far too small to fill up my computer's ram : half a gig). My problem comes from the cumbersome manner in which I need to program the operations of the dictionary. I often have stretches of code that go like this: for mk in dic.keys(): for rgk in dic[mk].keys(): for nk in dic[mk][rgk].keys(): for ik in dic[mk][rgk][nk].keys(): for ek in dic[mk][rgk][nk][ik].keys(): #do something which is ugly, cumbersome, non reusable, and brittle (need to recode it for any variant of the dictionary). I tried using recursive functions, but apart from the simplest applications, I ran into some very nasty bugs and bizarre behaviors that caused a big waste of time (it does not help that I don't manage to debug with pdb in ipython when I'm dealing with deeply nested recursive functions). In the end the only recursive function I use regularly is the following: def dicExplorer(dic, depth = -1, stp = 0): '''prints the hierarchy of a dictionary. if depth not specified, will explore all the dictionary ''' if depth - stp == 0: return try : list_keys = dic.keys() except AttributeError: return stp += 1 for key in list_keys: else: print '+%s> [\'%s\']' %(stp * '---', key) dicExplorer(dic[key], depth, stp) I know I'm doing this wrong, because my code is long, noodly and non-reusable. I need to either use better techniques to flexibly manipulate the dictionaries, or to put the data in some database format (sqlite?). My problem is that since I'm (badly) self-taught in regards to programming, I lack practical experience and background knowledge to appreciate the options available. I'm ready to learn new tools (SQL, object oriented programming), whatever it takes to get the job done, but I am reluctant to invest my time and efforts into something that will be a dead end for my needs. So what are your suggestions to tackle this issue, and be able to code my tools in a more brief, flexible and re-usable manner?
