  • How to hide check all, clear all checkbox

    - by Kalpana
    I am having check box in the column header. The function of this is to check or uncheck all the check boxes in that column.If the row check box is checked and say delete, that row can be deleted from the dataTable. If the row object is used in some other table as a foreign key i put '-' in that row instead of check box which indicates that row cannot be deletable. In these cases if all the row has '-" , there is no need to have the header check box. How to programatically hide this 'Check All | Clear All' check box, if there is nothing to be removed. It would be even preferable to hide the 'Remove' button if there is no selection to be made. What are the best practices to address the above scenario. I have attached the javascript which I am using. <script type="text/javascript"> var tableId = '#user\\:userList'; jQuery(document).ready(function() { jQuery('#selectAll').click(function() { jQuery(tableId).find("input[type='checkbox']").attr('checked', jQuery('#selectAll').is(':checked')); }); }); </script>

  • CakePHP 1.3 and Uploadifive/Uploadify - Change Upload Filename to a random string

    - by CaboONE
    I have somehow implemented UPLOADIFIVE in my CakePHP application. Everything seems to work great including uploading multiple files and inserting the correct information in the Database. Based on the following code, I would like to UPLOAD AND SAVE EVERY FILE WITH A RANDOM NAME TAKING INTO ACCOUNT THE CURRENT DATE OR SOMETHING SIMILAR. How could I accomplish this? In my Photos Controller I have the following function: // This function is called at every file upload. It uploads the file onto the server // and save the corresponding image name, etc, to the database table `photos`. function upload() { $uploadDir = '/img/uploads/photos/'; if (!empty($_FILES)) { debug($_FILES); $tempFile = $_FILES['Filedata']['tmp_name'][0]; $uploadDir = $_SERVER['DOCUMENT_ROOT'] . $uploadDir; $targetFile = $uploadDir . $_FILES['Filedata']['name'][0]; // Validate the file type $fileTypes = array('jpg', 'jpeg', 'gif', 'png'); // Allowed file extensions $fileParts = pathinfo($_FILES['Filedata']['name'][0]); // Validate the filetype if (in_array($fileParts['extension'], $fileTypes)) { // Save the file move_uploaded_file($tempFile,$targetFile); $_POST['image'] = $_FILES['Filedata']['name'][0]; $this->Photo->create(); if ($this->Photo->save($_POST)) { $this->Session->setFlash($targetFile, 'default', array('class' => 'alert_success')); $this->redirect(array('action' => 'index')); } } else { // The file type wasn't allowed //echo 'Invalid file type.'; $this->Session->setFlash(__('The photo could not be saved. Please, try again.', true)); } } } In my View file - admin_add.ctp I have added the following function $('#file_upload').uploadifive({ 'auto' : false, 'uploadScript' : '/photos/upload', 'buttonText' : 'BROWSE FILES', 'method' : 'post', 'onAddQueueItem' : function(file) { this.data('uploadifive').settings.formData = { 'photocategory_id' : $('#PhotoPhotocategoryId').val() }; } }); <input type="file" name="file_upload" id="file_upload" />

  • How to serve tiff WMS imagery through GeoServer

    - by mikem419
    Ok so I am new to the GeoServer/database world. I am a student intern and I have been given the task of setting up a WMS using GeoServer. I have never done any database work before this so bare with me if my questions leave out important information. I am using GeoServer 2.0.1 in standalone mode (downloaded using Jetty) with PostgreSQL 8.4 installed. I went through nyc_roads and nyc_buildings install demo in the GeoServer documentation but I still do not understand how I should go about serving up some test images. I noticed that the nyc_roads setup included a .sql file that was responsible for setting up the nyc_buildings database. I do not know how/where this file was generated. Our test images are .tiff and .jpeg. I have successfully been able to do a WMS call on the local GeoServer machine, and have opened the included demo imagery. I now wish to add these .tiff and .jpeg images to GeoServer and access them through WMS. I have tried copying the images to the GeoServer data directory,adding a new data store, and layers, but I always receive an error regarding the "input stream." Again I am very sorry if I am leaving out allot of vital information, this is as much as I know. thanks!

  • Html.LabelFor and Html.TextBoxFor generate empy html code

    - by Ceridan
    I'm writing my first ASP.NET MVC application and there is one big problem for me. I want to make a control which will represent a form, but when I try to generate labels and textboxes it returns to me empty page. So, this is my model file (MyModel.cs): namespace MyNamespace.Models { public class MyModel { [Required(ErrorMessage = "You have to fill this field")] [DisplayName("Input name")] public string Name{ get; set; } } } This is MyFormControlView.ascx file with my control: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<MyNamespace.Models.MyModel>"%> <div> <% using (Html.BeginForm()) { Html.LabelFor(m => m.Name); Html.TextBoxFor(m => m.Name); Html.ValidationMessageFor(m => m.Name); } %> </div> And this is my Index.aspx file where I render the control: <%@ Page Language="C#" MasterPageFile="~/Views/Shared/Main.Master" Inherits="System.Web.Mvc.ViewPage<System.Collections.IEnumerable>" %> <asp:Content runat="server" ID="MainContent" ContentPlaceHolderID="MainContent"> This is my control test! <%Html.RenderPartial("MyFormControlView", new MyNamespace.Models.MyModel { Name = "MyTestName"}); %> </asp:Content> So, when I run my application the result is lonely caption: "This is my control test!" and there are no label or textbox on the generated page. If I inspect the source code of the generated page I can see my block, but it's inner text is empty. Please, could you help me?

  • C# Regex - Replace multiple characters at once without overwriting?

    - by Everaldo Aguiar
    Hello guys, I'm implementing a c# program that should automatize a Mono-alphabetic substitution cipher. The functionality i'm working on at the moment is the simplest one: The user will provide a plain text and a cipher alphabet, for example: Plain text(input): THIS IS A TEST Cipher alphabet: A - Y, H - Z, I - K, S - L, E - J, T - Q Cipher Text(output): QZKL KL QJLQ I thought of using regular expressions since I've been programming in perl for a while, but I'm encountering some problems on c#. First I would like to know if someone would have a suggestion for a regular expression that would replace all occurrence of each letter by its corresponding cipher letter (provided by user) at once and without overwriting anything. Example: In this case, user provides plaintext "TEST", and on his cipher alphabet, he wishes to have all his T's replaced with E's, E's replaced with Y and S replaced with J. My first thought was to substitute each occurrence of a letter with an individual character and then replace that character by the cipherletter corresponding to the plaintext letter provided. Using the same example word "TEST", the steps taken by the program to provide an answer would be: 1 - replace T's with (lets say) @ 2 - replace E's with # 3 - replace S's with & 4 - Replace @ with E, # with Y, & with j 5 - Output = EYJE This solution doesn't seem to work for large texts. I would like to know if anyone can think of a single regular expression that would allow me to replace each letter in a given text by its corresponding letter in a 26-letter cipher alphabet without the need of splitting the task in an intermediate step as I mentioned. If it helps visualize the process, this is a print screen of my GUI for the program: http://img43.imageshack.us/img43/2118/11618743.jpg

  • Problems reading RSS feed with jQuery.get()

    - by bbeckford
    Hi there, I've been pulling my hair out trying to use jQuery.get() to pull in my dynamically generated RSS feed and I'm having nothing but issues, is my RSS feed the wrong format? If so can I convert it to the correct format using javascript? Here's my feed: http://dev.chriscurddesign.co.uk/burns/p/rc_rss.php?rcf_id=0 Here's my code: function get_rss_feed() { $(".content").empty(); $.get("http://dev.chriscurddesign.co.uk/burns/p/rc_rss.php?rcf_id=0", function(d) { var i = 0; $(d).find('item').each(function() { var $item = $(this); var title = $item.find('title').text(); var link = $item.find('link').text(); var location = $item.find('location').text(); var pubDate = $item.find('pubDate').text(); var html = '<div class="entry"><a href="' + link + '" target="_blank">' + title + '</a></div>'; $('.content').append(html); i++; }); }); }; Any input would be greatly appreciated!!

  • Trying to save file from Flash to PHP using $GLOBALS["HTTP_RAW_POST_DATA"]

    - by jolyonruss
    Let me start by saying PHP isn't my forte, I'm usually reluctant to try working with it because of problems exactly like this. The code works fine on my local machine under MAMP and on my server, but doesn't on the clients server :'( So what am I trying to do, well - save an image from Flash onto the server, simple right?! I'm using the method described on this site here: http://designreviver.com/tutorials/actionscript-3-jpeg-encoder-revealed-saving-images-from-flash/ but have made a small alteration so that instead of echoing the jpg causing the browser to download it locally, I do an fwrite and an fclose to save it to the server. Here is my PHP: $imageFile = '../images/' . $_GET['name']; $imageHandle = fopen($imageFile, "w"); fwrite($imageHandle, $jpg); fclose($imageHandle); } ? I've dona a phpinfo() on my clients server and it's running 5.2.2 my host is running 5.2.11 I don't know if much can have changed in those 9 minor revisions? I've also read another question on here which suggests making suer always_populate_raw_post_data is set to ON, but it's set to OFF on all of the server environments I've been testing in. I'm doing some XML saving using file_get_contents('php://input') which I've tried but failed to get working with images. Any help would be gratefully received, I'm happy to post the AS3 as well but it's EXACTLY the same as example I've linked above and works locally. As far as I can tell the problem lies with the PHP. Cheers.

  • ASP.NET Ajax - Asynch request has separate session???

    - by Marcus King
    We are writing a search application that saves the search criteria to session state and executes the search inside of an asp.net updatepanel. Sometimes when we execute multiple searches successively the 2nd or 3rd search will sometimes return results from the first set of search criteria. Example: our first search we do a look up on "John Smith" - John Smith results are displayed. The second search we do a look up on "Bob Jones" - John Smith results are displayed. We save all of the search criteria in session state as I said, and read it from session state inside of the ajax request to format the DB query. When we put break points in VS everything behaves as normal, but without them we get the original search criteria and results. My guess is because they are saved in session, that the ajax request somehow gets its own session and saves the criteria to that, and then retrieves the criteria from that session every time, but the non-async stuff is able to see when the criteria is modified and saves the changes to state accordingly, but because they are from two different sessions there is a disparity in what is saved and read. EDIT::: To elaborate more, there was a suggestion of appending the search criteria to the query string which normally is good practice and I agree thats how it should be but following our requirements I don't see it as being viable. They want it so the user fills out the input controls hits search and there is no page reload, the only thing they see is a progress indicator on the page, and they still have the ability to navigate and use other features on the current page. If I were to add criteria to the query string I would have to do another request causing the whole page to load, which depending on the search criteria can take a really long time. This is why we are using an ajax call to perform the search and why we aren't causing another full page request..... I hope this clarifies the situation.

  • jquery autocomplete & masterpage

    - by Caroline
    Hi everyone, first time posting here, so hello to all :-) I'm pretty new to the jQuery thing, but I got the autocomplete function running quite well on a simple aspx page. Now I wanted to use the same function on an aspx-page with a masterpage, and it doesnt work anymore. this test function works fine: $(document).ready(function () { $("[id$=AlertButton]").click(function () { alert("Welcome jQuery !"); }); }); but this simply does nothing: $(document).ready(function () { $("[id$=Suchen]").autocomplete("AutocompleteData.ashx"); }); the javascript and css files are loaded in the master page, just above the contentplaceholder. the code within the contentplaceholder looks like this: <atlas:ScriptManager id="SM1" runat="server" EnablePartialRendering="true" > <Services> <atlas:servicereference path="~/xxxxx.asmx" /> </Services> </atlas:ScriptManager> <script type="text/javascript"> $(document).ready(function () { $("[id$=Suchen]").autocomplete("AutocompleteData.ashx"); }); </script> <br /> <asp:Button ID="AlertButton" runat="server" Text="Button" /> <br /> <asp:TextBox ID="Suchen" Width="250" runat="server"></asp:TextBox> if I execute the .ashx page on its own, it fires back the expected data... I've been browsing tons of pages, but couldn't resolve the issue. I'd be glad for any input!!! Thanks alot & all the best, Caroline

  • Access custom error messages for InArray validator when using Zend_Form_Element_Select

    - by Ben Waine
    Hello, I'm using Zend Framework 1.62 (becuase we are deploying the finished product to a Red Hat instance, which doesn't have a hgih enough PHP version to support ZF1.62). When creating a Form using Zend Form, I add a select element, add some multi options. I use the Zend Form as an in-object validation layer, passing an objects values through it and using the isValid method to determine if all the values fall within normal parameters. Zend_Form_Element_Select works exactly as expected, showing invalid if any other value is input other than one of the multi select options I added. The problem comes when I want to display the form at some point, I cant edit the error message created by the pre registered 'InArray' validator added automatically by ZF. I know I can disable this behaviour, but it works great apart from the error messages. I've tryed the following: $this->getElement('country')->getValidator('InArray')->setMessage('The country is not in the approved lists of countries'); // Doesn't work at all. $this->getElement('country')->setErrorMessage('The country is not in the approved lists of countries'); // Causes a conflict elswhere in the application and doesnt allow granular control of error messages. Anyone have any ideas? Ben

  • Silverlight 4, Out of browser, Printing, Automatic updates

    - by minal
    I have a very critial business application presently running using Winforms. The application is a very core UI shell. It accepts input data, calls a webservice on my server to do the computation, displays the results on the winforms app and finally send a print stream to the printer. Presently the application is deployed using Click-once. Moving forward, I am trying to contemplate wheather I should move the application into a Silverlight application. Couple of reasons I am thinking silverlight. Gives clients the feel that it is a cloud based solution. Can be accessed from any PC. While the clickonce app is able to do this as well, they have to install an app, and when updates are available they have to click "Yes" to update. The application presently has a drop down list of customers, this list has expanded to over 3000 records. Scrolling through the list is very painful. With Silverlight I am thinking of the auto complete ability. Out of the browser - this will be handy for those users who use the app daily. I haven't used Silverlight previous hence looking for some expert advice on a few things: Printing - does silverlight allow sending raw print data to the printer. The application prints to a Zebra Thermal label printer. I have to send raw bytes to the printer with the commands. Can this be done with SL, or will it always prompt the "Print" dialog? Out of browser - when SL apps are installed as out of browser, how to updates come through, does the app update automatically or is the user prompted to opt for update?

  • c++ OpenCV CVCalibrateCamera2 is causing multiple errors

    - by tlayton
    I am making a simple calibration program in C++ using OpenCV. Everything goes fine until I actually try to call CVCalibrateCamera2. At this point, I get one of several errors: If the number of images which I am using is equal to 4 (which is the number of points being drawn from each image: OpenCV Error: Sizes of input arguments do not match (Both matrices must have the same number of points) in unknown function, file ......\src\cv\cvfundam.cpp, line 870 If the number of images is below 20: OpenCV Error: Bad argument (The total number of matrix elements is not divisible by the new number of rows) in unknown function, file ......\src\cxcore\cxarray.cpp, line 2749 Otherwise, if the number of image is 20 or above: OpenCV Error: Unsupported format or combination of formats (Invalid matrix type) in unknown function, file ......\src\cxcore\cxarray.cpp, line 117 I have checked the arguments for CVCalibrateCamera2 many times, and I am certain that they are of the correct dimensions relative to one another. It seems like somewhere the program is trying to reshape a matrix based on the number of images, but I can't figure out where or why. Any ideas? I am using Eclipse Galileo, MINGW 5.1.6, and OpenCV 2.1.

  • javascript - catch SyntaxError and run alternate function

    - by ludicco
    Hello there, I'm trying to build something on javascript that I can have an input that can be everything like string, xml, javascript and (non-javascript string without quotes) as follows: //strings eval("'hello I am a string'"); /* note the following proper quote marks */ //xml eval(<p>Hello I am a XML doc</p>); //javascript eval("var hello = 2+2;"); So this first 3 are working well since they are simple javascript native formats but when I try use this inside javascript //plain-text without quotes eval("hello I am a plain text without quotes"); //--SyntaxError: missing ; before statement:--// Obviously javascript interprets this as syntax error because it thinks its javascript throwing a SyntaxError. So what I would like to do it to catch this error and perform the adjustment method if this occurs. I've already tried with try catch but it doesn't work since it keeps returning the Syntax error as soon as it tries to execute the code. Any help would be much appreciated Cheers :) Additional Information: Imagine an external file that javascript would read, using spidermonkey, so it's a non-browser stuff(I can't use HttpRequest, DOM, etc...)..not sure if this matters, but there it is. :)

  • which xml validator will work perfectly for multithreading project

    - by Sunil Kumar Sahoo
    Hi All, I have used jdom for xml validation against schema. The main problem there is that it gives an error FWK005 parse may not be called while parsing The main reason was that multiple of threads working for xerces validation at the same time. SO I got the solution that i have to lock that validation. which is not good So I want to know which xml validator works perfectly for multithreading project public static HashMap validate(String xmlString, Validator validator) { HashMap<String, String> map = new HashMap<String, String>(); long t1 = System.currentTimeMillis(); DocumentBuilder builder = null; try { //obtain lock to proceed // lock.lock(); try { builder = DocumentBuilderFactory.newInstance().newDocumentBuilder(); // Source source = new DOMSource(builder.parse(new ByteArrayInputStream(xmlString.getBytes()))); validator.validate(new StreamSource(new StringReader(xmlString))); map.put("ISVALID", "TRUE"); logger.info("We have successfuly validated the schema"); } catch (Exception ioe) { ioe.printStackTrace(); logger.error("NOT2 VALID STRING IS :" + xmlString); map.put("MSG", ioe.getMessage()); // logger.error("IOException while validating the input XML", ioe); } logger.info(map); long t2 = System.currentTimeMillis(); logger.info("XML VALIDATION TOOK:::" + (t2 - t1)); } catch (Exception e) { logger.error(e); } finally { //release lock // lock.unlock(); builder = null; } return map; } Thanks Sunil Kumar Sahoo

  • Using HAML with custom filters

    - by Guard
    Hi everybody. I feel quite excited about HAML and CoffeeScript and am working on tutorial showing how to use them in non-Rails environment. So, haml has easy to use command-line utility haml input.haml output.html. And, what is great, there exist a project (one of many forks: https://github.com/aussiegeek/coffee-haml-filter) aimed at providing custom filter that converts CoffeeScript into JS inside of HAML files. Unfortunately (or am I missing something?) haml doesn't allow specifying custom filters on the command line or with some configuration file. I (not being a Ruby fan or even knowing it enough) managed to solve it (based on some clever suggestion somewhere on SO) with this helper script: haml.rb require 'rubygems' require 'active_support/core_ext/object/blank' require 'haml' require 'haml/filters/coffee' template = ARGV.length > 0 ? File.read(ARGV.shift) : STDIN.read haml_engine = Haml::Engine.new(template) file = ARGV.length > 0 ? File.open(ARGV.shift, 'w') : STDOUT file.write(haml_engine.render) file.close Which is quite straightforward, except of requires in the beginning. Now, the questions are: 1) should I really use it, or is there another way to have on-demand HAML to HTML compilation with custom filters? 2) What about HAML watch mode? It's great and convenient. I can, of course, create a polling script in python that will watch the directory changes and call this .rb script, but it looks like a dirty solution.

  • Passing char * into fopen with C.

    - by Rhys
    Hey there, I'm writing a program that passes data from a file into an array, but I'm having trouble with fopen (). It seems to work fine when I hardcode the file path into the parameters (eg fopen ("data/1.dat", "r");) but when I pass it as a pointer, it returns NULL. Note that line 142 will print "data/1.dat" if entered from command line so parse_args () appears to be working. 132 int 133 main(int argc, char **argv) 134 { 135 FILE *in_file; 136 int *nextItem = (int *) malloc (sizeof (int)); 137 set_t *dictionary; 138 139 /* Parse Arguments */ 140 clo_t *iopts = parse_args(argc, argv); 141 142 printf ("INPUT FILE: %s.\n", iopts->input_file); /* This prints correct path */ 143 /* Initialise dictionary */ 144 dictionary = set_create (SET_INITAL_SIZE); 145 146 /* Use fscanf to read all data values into new set_t */ 147 if ((in_file = fopen (iopts->input_file, "r")) == NULL) 148 { 149 printf ("File not found...\n"); 150 return 0; 151 } Thanks!

  • Login to website using PHP and get text from page

  • Parsec: backtracking not working

    - by Nathan Sanders
    I am trying to parse F# type syntax. I started writing an [F]Parsec grammar and ran into problems, so I simplified the grammar down to this: type ::= identifier | type -> type identifier ::= [A-Za-z0-9.`]+ After running into problems with FParsec, I switched to Parsec, since I have a full chapter of a book dedicated to explaining it. My code for this grammar is typeP = choice [identP, arrowP] identP = do id <- many1 (digit <|> letter <|> char '.' <|> char '`') -- more complicated code here later return id arrowP = do domain <- typeP string "->" range <- typeP return $ "("++domain++" -> "++range++")" run = parse (do t <- typeP eof return t) "F# type syntax" The problem is that Parsec doesn't backtrack by default, so > run "int" Right "int" -- works! > run "int->int" Left "F# type syntax" unexpected "-" expecting digit, letter, ".", "`" or end of input -- doesn't work! The first thing I tried was to reorder typeP: typeP = choice [arrowP, identP] But this just stack overflows because the grammar is left-recursive--typeP never gets to trying identP because it keeps trying arrowP over and over. Next I tried try in various places, for example: typeP = choice [try identP, arrowP] But nothing I do seems to change the basic behaviours of (1) stack overflow or (2) non-recognition of "-" following an identifier. My mistake is probably obvious to anybody who has successfully written a Parsec grammar. Can somebody point it out?

  • Extracting bool from istream in a templated function

    - by Thomas Matthews
    I'm converting my fields class read functions into one template function. I have field classes for int, unsigned int, long, and unsigned long. These all use the same method for extracting a value from an istringstream (only the types change): template <typename Value_Type> Value_Type Extract_Value(const std::string& input_string) { std::istringstream m_string_stream; m_string_stream.str(input_string); m_string_stream.clear(); m_string_stream >> value; return; } The tricky part is with the bool (Boolean) type. There are many textual representations for Boolean: 0, 1, T, F, TRUE, FALSE, and all the case insensitive combinations Here's the questions: What does the C++ standard say are valid data to extract a bool, using the stream extraction operator? Since Boolean can be represented by text, does this involve locales? Is this platform dependent? I would like to simplify my code by not writing my own handler for bool input. I am using MS Visual Studio 2008 (version 9), C++, and Windows XP and Vista.

    Hello, I have this piece of code which I'm hoping will be able to tell me how much data I have downloaded (and soon put it in a progress bar), and then parse the results through my Sax Parser. If I comment out basically everything above the //xr.parse(new InputSource(request.getInputStream())); line and swap the xr.parse's over, it works fine. But at the moment, my Sax parser tells me I have nothing. Is it something to do with is.read (buffer) section? Also, just as a note, request is a HttpURLConnection with various signatures. /*Input stream to read from our connection*/ InputStream is = request.getInputStream(); /*we make a 2 Kb buffer to accelerate the download, instead of reading the file a byte at once*/ byte [ ] buffer = new byte [ 2048 ] ; /*How many bytes do we have already downloaded*/ int totBytes,bytes,sumBytes = 0; totBytes = request.getContentLength () ; while ( true ) { /*How many bytes we got*/ bytes = is.read (buffer); /*If no more byte, we're done with the download*/ if ( bytes <= 0 ) break; sumBytes+= bytes; Log.v("XML", sumBytes + " of " + totBytes + " " + ( ( float ) sumBytes/ ( float ) totBytes ) *100 + "% done" ); } /* Parse the xml-data from our URL. */ // OLD, and works if comment all the above //xr.parse(new InputSource(request.getInputStream())); xr.parse(new InputSource(is)) /* Parsing has finished. */; Can anyone help me at all?? Kind regards, Andy

  • Websphere logs report {0} File not found, but application continues to work without issues

    - by Eric
    A websphere 6.1 server is running a struts application that seems to be working fine. In the logs, however, I'm seeing the following error message, which is being continually emailed to the support staff. com.ibm.ws.webcontainer.webapp.WebAppErrorReport: SRVE0190E: File not found: {0} at com.ibm.ws.webcontainer.webapp.WebAppDispatcherContext.sendError(WebAppDispatcherContext.java:536) at com.ibm.ws.webcontainer.srt.SRTServletResponse.sendError(SRTServletResponse.java:930) at com.ibm.ws.webcontainer.extension.DefaultExtensionProcessor.handleRequest(DefaultExtensionProcessor.java:524) at com.ibm.ws.wswebcontainer.extension.DefaultExtensionProcessor.handleRequest(DefaultExtensionProcessor.java:111) at com.ibm.ws.webcontainer.webapp.WebApp.handleRequest(WebApp.java:3129) at com.ibm.ws.webcontainer.webapp.WebGroup.handleRequest(WebGroup.java:238) at com.ibm.ws.webcontainer.WebContainer.handleRequest(WebContainer.java:811) at com.ibm.ws.wswebcontainer.WebContainer.handleRequest(WebContainer.java:1433) at com.ibm.ws.webcontainer.channel.WCChannelLink.ready(WCChannelLink.java:93) I can narrow down the issue to a single Action and JSP, which are too big to show here, but here's the action definition in struts-config.xml: <action path="/HappyDefaultThing" name="HappyDefaultThingActionForm" type="com.foo.webadministration.action.HappyDefaultThingAction" validate="true" input="/WaAssignDefaultHappyThing.jsp" scope="session"> <forward name="success" path="/WaAssignDefaultHappyThing.jsp"/> <forward name="failure" path="/WaAssignDefaultHappyThing.jsp"/> </action> As far as I can see, nothing is missing, and everything necessary is being found, but the logs say "File not found: {0}" What is "{0}"?? The stack trace only shows IBMs code, which I can't see the source of, and therefore can't trace. Is this a bug in the websphere code? I'd appreciate any help.

  • events not firing in VisualForce

    - by Ben
    In the page below,Topic__c is a single-select picklist. My intention is to have this list control which of the input fields is available below. The user selects an option, and the onchange event should fire, and rerender the fields. <apex:inputField value="{!Call_Report__c.Topic__c}" id="topic" > <apex:actionSupport event="onchange" reRender="tickerInput,sectorInput,bondInput"> <apex:param name="topicSelection" value="{!Call_Report__c.Topic__c}" /> </apex:actionSupport> </apex:inputField> <apex:inputField value="{!Call_Report__c.Tickers__c}" rendered="{!Call_Report__c.Topic__c='Issuer'}" id="tickerInput" /> <apex:inputField value="{!Call_Report__c.Sector__c}" rendered="{!Call_Report__c.Topic__c='Industry'}" id="sectorInput"/> <apex:inputField value="{!Call_Report__c.Security__c}" rendered="{!Call_Report__c.Topic__c='Specific Bond'}" id="bondInput" /> Am I doing something obviously wrong here? http://community.salesforce.com/t5/Visualforce-Development/Multi-select-picklist-not-firing-event-for-AJAX-refreshes/m-p/173572/highlight/false#M22119 seems to imply that what I am doing is reasonable...

  • How to retain XML string as a string field during XML deserialization

    - by detale
    I got an XML input string and want to deserialize it to an object which partially retain the raw XML. <SetProfile> <sessionId>A81D83BC-09A0-4E32-B440-0000033D7AAD</sessionId> <profileDataXml> <ArrayOfProfileItem> <ProfileItem> <Name>Pulse</Name> <Value>80</Value> </ProfileItem> <ProfileItem> <Name>BloodPresure</Name> <Value>120</Value> </ProfileItem> </ArrayOfProfileItem> </profileDataXml> </SetProfile> The class definition: public class SetProfile { public Guid sessionId; public string profileDataXml; } I hope the deserialization syntax looks like string inputXML = "..."; // the above XML XmlSerializer xs = new XmlSerializer(typeof(SetProfile)); using (TextReader reader = new StringReader(inputXML)) { SetProfile obj = (SetProfile)xs.Deserialize(reader); // use obj .... } but XMLSerializer will throw an exception and won't output < profileDataXml 's descendants to "profileDataXml" field in raw XML string. Is there any way to implement the deserialization like that?
