  • Add jar to EAR in Eclipse

    - by Gerard
    I have several projects in an EAR in Eclipse. These projects themselves have dependency jar's on the build path marked as "do not export, do not contribute to others". Now in Eclipse I add jar's to the EAR via the EAR properties "Java EE Module Dependencies". I browse to the jar (add jar) and click ok. The jar is added to the list. When I click apply, the added jar is gone from the list, it cannot be found in other properties, it is contained in the hidden folder .settings in the file org.eclipse.wst.common.component. This behaviour does not make much sense to me, what am I missing?

  • Winform BindingSources - Question

    - by Stephen Patten
    I have a windows form (net 2.0) with controls on it bound to an entity (w/ INotifyPropertyChanged) through a BindingSource..works. On the same form I have a drop down list that is also wired up through a BindingSource..works Here's a sample of the relevant code: m_PlanItemLookupBindingSource.DataSource = GetBusinessLogic().RetrievePaymentPlanLookups(); // Collection of PaymentPlans paymentPlanType.Properties.DataSource = m_PlanItemLookupBindingSource; paymentPlanType.Properties.DisplayMember = "Name"; paymentPlanType.Properties.ValueMember = "ID"; paymentPlanType.DataBindings.Add(new Binding("EditValue", m_PlanBindingSource, "PaymentPlanID", true, DataSourceUpdateMode.OnPropertyChanged, null, "D")); agencyComission.DataBindings.Add(new Binding("EditValue", m_PlanBindingSource, "AgencyCommission", true, DataSourceUpdateMode.OnPropertyChanged, null, "P1")); billingType.DataBindings.Add(new Binding("Text", m_PlanBindingSource, "BillingType")); So when I change a value in the drop down list I thought that the m_PlanItemLookupBindingSource Current property would change along with the PaymentPlanID property of the entity which does change. Just a bit confused. Thanks in advance, Stephen

  • Linking to an Apache License 2.0 library and distributing with proprietary application

    - by atnakjp
    Hi all, I've read through "Apache License, Version 2.0" but my interpretation was in slightly different to an answer given in a related question so was hoping for some clarification. Supposing I created an application that linked to a library that was licensed under the license in question, my interpretation for doing what's required is: I don't need to do anything special to the application itself because it's considered neither "Work" nor "Derivative Works". When distributing the library alongside the application, I need to include a copy of the license. Any installer that contains the library would be considered "Derivative Works" and therefore I would need to show the attribution notices contained in "NOTICE" (if one exists) in one of its screens. If I were to distribute everything in a zip file instead, I would need to put the same attribution notices in a text file that I distribute alongside the file. Does this sound about right? Cheers,

  • Retrieve a facebook page's type

    - by HectorMac
    I am trying to display a list of pages similar to the facebook search results. Along with the page's name, I would like to display the page type. The page's type property (from the Pages.getInfo API call returns the rather unfriendly looking strings from this list: http://wiki.developers.facebook.com/index.php/Page_Types Is there any way to map these to or retrieve the actual type descriptions facebook uses for page types in the facebook search results? These are not only more presentable, but appear to be less granular (both good things for my purpose).

  • How should I manage data in an 2D vector based animation program?

    - by shadow
    I've been trying to design a program that makes 2D animations and then uses the ffmpeg library to create the video for possible use in tv and movies. The problem is when I think about how to manage the data in the application I can only think of two ways, I don't think either of them will work out very well. One is to use an SQlite database, but it seems like it will be difficult to save, especially if an artist puts 1000 things on screen. The other is to use something like linked lists, which would duplicate many features of the database and get complicated when dealing with things like points on a bezier curve and jumping to a frame and collecting all the objects that need to be drawn on that frame. Should I use one of these solutions, or is there something else that would be better? Currently planning to use C# for code.

  • 301 Redirects, and the correct regex to go with it

    - by Tisch
    Hi Guys, I have several URLs that I want to redirect to the same place, however these are dynamic URLs. The structure is something like this: http://www.mysite.com/declaration/list?[query_string] What I think would be ideal for this situation is to use some regex in my .htaccess file to redirect all these links to the sites home page. I was wondering if someone could help me with the regex for this situation. So far, I have this, but it doesn't work: RewriteCond %{QUERY_STRING} ^(.*)$ RewriteRule ^/declaration/list$ http://www.mysite.com/$ [R=301,L] My regex is weak to say the least, something I want to, and am trying to learn. Thanks in advance. Tom

  • How well do zippers perform in practice, and when should they be used?

    - by Rob
    I think that the zipper is a beautiful idea; it elegantly provides a way to walk a list or tree and make what appear to be local updates in a functional way. Asymptotically, the costs appear to be reasonable. But traversing the data structure requires memory allocation at each iteration, where a normal list or tree traversal is just pointer chasing. This seems expensive (please correct me if I am wrong). Are the costs prohibitive? And what under what circumstances would it be reasonable to use a zipper?

  • JavaFX: Update of ListView if an element of ObservableList changes

    - by user1828169
    I would like to display a list of persons (coded in POJOS, and containing a name and surname property) using a JavaFX ListView control. I created the ListView and added the list of persons as an ObservableList. Everything works fine if I delete or add a new person to the ObservableList, but changes in the POJO do not trigger an update of the ListView. I have to remove and add the modified POJO from the ObservableList to trigger the update of the ListView. Is there any possibility to display changes in POJOS without the workaround described above?

  • Spring validation errors not displayed

    - by Art Vandelay
    I have the following situation. I have a validator to validate my command object and set the errors on a Errors object to be displayed in my form. The validator is invoked as expected and works okay, but the errors i set on the Errors objects are not displayed, when i am sent back to my form because of the validation errors. Validator: public void validate(Object obj, Errors err) { MyCommand myCommand = (MyCommand) obj; int index = 0; for (Field field : myCommand.getFields()) { if (field.isChecked()) { if ((field.getValue() == null) || (field.getValue().equals(""))) { err.rejectValue("fields[" + index + "].value", "errors.missing"); } } index++; } if (myCommand.getLimit() < 0) { err.rejectValue("limit", "errors.invalid"); } } Command: public class MyCommand { private List<Field> fields; private int limit; //getters and setters } public class Field { private boolean checked; private String name; private String value; //getters and setters } Form: <form:form id="myForm" method="POST" action="${url}" commandName="myCommand"> <c:forEach items="${myCommand.fields}" var="field" varStatus="status"> <form:checkbox path="fields[${status.index}].checked" value="${field.checked}" /> <c:out value="${field.name}" /> <form:input path="fields[${status.index}].value" /> <form:errors path="fields[${status.index}].value" cssClass="error" /></td> <form:hidden path="fields[${status.index}].name" /> </c:forEach> <fmt:message key="label.limit" /> <form:input path="limit" /> <form:errors path="limit" cssClass="error" /> </form:form> Controller: @RequestMapping(value = REQ_MAPPING, method = RequestMethod.POST) public String onSubmit(Model model, MyCommand myCommand, BindingResult result) { // validate myCommandValidator.validate(myCommand, result); if (result.hasErrors()) { model.addAttribute("myCommand", myCommand); return VIEW; } // form is okay, do stuff and redirect } Could it be that the paths i give in the validator and tag are not correct? The validator validates a command object containing a list of objects, so that's why i give a index on the list in the command object when registering an error message (for example: "fields["+index+"]".value). Or is it that the Errors object containing the errors is not available to my view? Any help is welcome and appreciated, it might give me a hint or point me in right direction.

  • Get children count via HQL

    - by Thomas Lötzer
    Hi, I have a one-to-many mapping between a parent entity and child entities. Now I need to find the number of children associated with each parent for a list of parents. I am trying to do this with HQL but I am not sure how I can get the list of parents in there. Also, I don't know how I can return the entity itself and not just its ID. My current HQL query is: select new map(parent.id as parentId, count(*) as childCount) from Parent parent left join parent.children children group by parent.id but this only returns the ID and does not filter on specific parents. EDIT Based on Pascal's answer I have modified the query to select new map(parent as parent, count(elements(parent.children)) as childCount) from Parent parent group by parent That does work, but is prohibitively slow: 30 seconds instead of 400 ms on the same database.

  • Haskell parsec parsing a string of items

    - by Chris
    I have a list that I need to parse where the all but the last element needs to be parsed by one parser, and the last element needs to be parsed by another parser. a = "p1 p1b ... p2" or a = "p2" Originally I tried parser = do parse1 <- many parser1 parse2 <- parser2 return AParse parse1 parse2 The problem is that parse1 can consume a parse2 input. So parse1 always consumes the entire list, and leave parse2 with nothing. Is there a way to say to apply parse1 to everything besides the last element in a string, and then apply parse2?

  • Converting a Doc object into a string in python

    - by Sam
    I'm using minidom to parse through an xml document. I took the data with yum tags and stored them in a list and calculated the frequency of the words. However, its not storing or reading them as strings in the list. Is there another way to do it? Right now this is what I have: yumNodes = [node for node in doc.getElementsByTagName("yum")] for node in yumNodes: yumlist.append(t.data for t in node.childNodes if t.nodeType == t.TEXT_NODE) for ob in yumlist: for o in ob: if word not in freqDict: freqDict[word] = 1 else: freqDict[word] += 1

  • Rails "Load more..." instead of pagination.

    - by Joseph Silvashy
    I have a list of elements, and I've been using will_paginate up until now, but I'd like to have something like "load more..." at the bottom of the list. Is there an easy way to accomplish this using will_paginate or do I need to resort to some other method here? From what I know this is a better route anyhow because then I don't need a SQL count of the records. And it really doesn't matter if there are like 9,847 pages, nobody would need the records beyond the first couple pages anyhow.

  • I need some help optimizing my database schema

    - by Steffan
    Here's a layout of my data: Heading 1: Sub heading Sub heading Sub heading Sub heading Sub heading Heading 2: Sub heading Sub heading Sub heading Sub heading Sub heading Heading 3: Sub heading Sub heading Sub heading Sub heading Sub heading Heading 4: Sub heading Sub heading Sub heading Sub heading Sub heading Heading 5: Sub heading Sub heading Sub heading Sub heading Sub heading These headings need to have a 'Completion Status' boolean value which gets linked to a user Id. Currently, this is how my table looks: id | userID | field_1 | field_2 | field_3 | field_4 | etc... ----------------------------------------------------------------------- 1 | 1 | 0 | 0 | 1 | 0 | ----------------------------------------------------------------------- 2 | 2 | 1 | 0 | 1 | 1 | Each field represents one Sub Heading. Having this many columns in my table looks awfully inefficient... How can I go about optimizing this? I can't think of any way to neaten it up :/

  • LINQ to Objects .Distinct() not pulling distinct objects

    - by Anthony Potts
    I have two ways that I am doing a fuzzy search for a customer. One is by an abbreviated name and the other is by the customers full name. When I take these two and then union them together (which I have read several places should remove distinct values) I get duplicates. Thinking that all I need to do is then call the .Distinct() method on this I also still get Duplicates. Do I need to implement some compare functionality in my customer object? My code: Dim shortNameMatch As List(Of ICustomer) = CustomerLibrary.GetCustomersByShortName(term) Dim custNameMatch As List(Of ICustomer) = CustomerLibrary.GetCustomersByCustName(term) Dim allMatch = (From a In (From s In shortNameMatch Select s).Union(From c In custNameMatch Select c) Select a).Distinct()

  • MEF part unable to import Autofac autogenerated factory

    - by Michael Wagner
    This is a (to me) pretty weird problem, because it was already running perfectly but went completely south after some unrelated changes. I've got a Repository which imports in its constructor a list of IExtensions via Autofacs MEF integration. One of these extensions contains a backreference to the Repository as Lazy(Of IRepository) (lazy because of the circular reference that would occur). But as soon as I try to use the repository, Autofac throws a ComponentNotRegisteredException with the message "The requested service 'ContractName=Assembly.IRepository()' has not been registered." That is, however, not really correct, because when I break right after the container-build and explore the list of services, it's there - Exported() and with the correct ContractName. I'd appreciate any help on this... Michael

  • Problem in JsonResult

    - by Saravanan I M
    I am using the jsonresult for listing all the cities under a country. I retrieve the data from database and load it to a dropdown list using jquery. The problem is if the cities goes beyond 3000 then the jsonresult is not working. <script type="text/javascript"> $(document).ready(function () { //Hook onto the MakeID list's onchange event $("#Country").change(function () { //build the request url $("#HomeTown").empty(); var url = '<%= Url.Content("~/") %>' + "Location/GetCitiesByCountry/" + $("#Country").val(); $.getJSON(url, function (data) { $.each(data, function (index, optionData) { $("#HomeTown").append("<option value='" + optionData.geonameid + "'>" + optionData.asciiname + "</option>"); }); $("#HomeTown").option[0].selected = true; }); }).change(); }); </script>

  • C# -Closure -Clarification

    - by nettguy
    I am learning C#.Can I mean closure as a construct that can adopt the changes in the environment in which it is defined. Example : List<Person> gurus = new List<Person>() { new Person{id=1,Name="Jon Skeet"}, new Person{id=2,Name="Marc Gravell"}, new Person{id=3,Name="Lasse"} }; void FindPersonByID(int id) { gurus.FindAll(delegate(Person x) { return x.id == id; }); } The variable id is declared in the scope of FindPersonByID() but t we still can access the local variable id inside the anonymous function (i.e) delegate(Person x) { return x.id == id; } (1) Is my understanding of closure is correct ? (2) What are the aditional advantages can we get from closures?

  • Windows Server 2003 Hacked - Files Being Uploaded

    - by jreedinc
    Blank directories are being created on my Windows Server 2003 virtual server with sub directories that are weird (for example: "88ÿ ÿ ÿÿþþ þþ13þ"). It looks like they are uploading bootlegged DVDs and pirated software. All of my bandwidth and file space is being eaten up. Could this be a shared permissions issue? Where should I look to further investigate this? My security permissions for the directory that is being hit are as followed: Administrators - ALL GRANTED IIS_WPG - Read & Execute, List Folder Contents, Read Internet Guest - DENY SYSTEM - ALL GRANTED Users - Read & Execute, List Folder Contents, Read My Event Viewer is showing many Logon/Logoff with NO IP?

  • Replace HTML entities in a string avoiding <img> tags

    - by Xeos
    I have the following input: Hi! How are you? <script>//NOT EVIL!</script> Wassup? :P LOOOL!!! :D :D :D Which is then run through emoticon library and it become this: Hi! How are you? <script>//NOT EVIL!</script> Wassup? <img class="smiley" alt="" title="tongue, :P" src="ui/emoticons/15.gif"> LOOOL!!! <img class="smiley" alt="" title="big grin, :D" src="ui/emoticons/5.gif"> <img class="smiley" alt="" title="big grin, :P" src="ui/emoticons/5.gif"> <img class="smiley" alt="" title="big grin, :P" src="ui/emoticons/5.gif"> I have a function that escapes HTML entites to prevent XSS. So running it on raw input for the first line would produce: Hi! How are you? &lt;script&gt;//NOT EVIL!&lt;/script&gt; Now I need to escape all the input, but at the same time I need to preserve emoticons in their initial state. So when there is <:-P emoticon, it stays like that and does not become &lt;:-P. I was thinking of running a regex split on the emotified text. Then processing each part on its own and then concatenating the string together, but I am not sure how easily can Regex be bypassed? I know the format will always be this: [<img class="smiley" alt="] [empty string] [" title="] [one of the values from a big list] [, ] [another value from the list (may be matching original emoticon)] [" src="ui/emoticons/] [integer from Y to X] [.gif">] Using the list MAY be slow, since I need to run that regex on text that may have 20-30-40 emoticons. Plus there may be 5-10-15 text messages to process. What could be an elegant solution to this? I am ready to use third-party library or jQuery for this. PHP preprocessing is possible as well.

  • Android - MapView contained within a Listview

    - by Ryan
    Hello, Currently I am trying to place a MapView within a ListView. Has anyone had any success with this? Is it even possible? Here is my code: ListView myList = (ListView) findViewById(android.R.id.list); List<Map<String, Object>> groupData = new ArrayList<Map<String, Object>>(); Map<String, Object> curGroupMap = new HashMap<String, Object>(); groupData.add(curGroupMap); curGroupMap.put("ICON", R.drawable.back_icon); curGroupMap.put("NAME","Go Back"); curGroupMap.put("VALUE","By clicking here"); Iterator it = data.entrySet().iterator(); while (it.hasNext()) { //Get the key name and value for it Map.Entry pair = (Map.Entry)it.next(); String keyName = (String) pair.getKey(); String value = pair.getValue().toString(); if (value != null) { //Add the parents -- aka main categories curGroupMap = new HashMap<String, Object>(); groupData.add(curGroupMap); //Push the correct Icon if (keyName.equalsIgnoreCase("Phone")) curGroupMap.put("ICON", R.drawable.phone_icon); else if (keyName.equalsIgnoreCase("Housing")) curGroupMap.put("ICON", R.drawable.house_icon); else if (keyName.equalsIgnoreCase("Website")) curGroupMap.put("ICON", R.drawable.web_icon); else if (keyName.equalsIgnoreCase("Area Snapshot")) curGroupMap.put("ICON", R.drawable.camera_icon); else if (keyName.equalsIgnoreCase("Overview")) curGroupMap.put("ICON", R.drawable.overview_icon); else if (keyName.equalsIgnoreCase("Location")) curGroupMap.put("ICON", R.drawable.map_icon); else curGroupMap.put("ICON", R.drawable.icon); //Pop on the Name and Value curGroupMap.put("NAME", keyName); curGroupMap.put("VALUE", value); } } curGroupMap = new HashMap<String, Object>(); groupData.add(curGroupMap); curGroupMap.put("ICON", R.drawable.back_icon); curGroupMap.put("NAME","Go Back"); curGroupMap.put("VALUE","By clicking here"); //Set up adapter mAdapter = new SimpleAdapter( mContext, groupData, R.layout.exp_list_parent, new String[] { "ICON", "NAME", "VALUE" }, new int[] { R.id.photoAlbumImg, R.id.rowText1, R.id.rowText2 } ); myList.setAdapter(mAdapter); //Bind the adapter to the list Thanks in advance for your help!!

  • How can I read/write data from a file?

    - by samy
    I'm writing a simple chrome extension. I need to create the ability to add sites URLs to a list, or read from the list. I use the list to open the sites in the new tabs. I'm looking for a way to have a data file I can write to, and read from. I was thinking on XML. I read there is a problem changing the content of files with Javascript. Is XML the right choice for this kinda thing? I should add that there is no web server, and the app will run locally, so maybe the problem websites are having are not same as this. Before I wrote this question, I tried one thing, and started to feel insecure because it didn't work. I made a XML file called Site.xml: <?xml version="1.0" encoding="utf-8" ?> <Sites> <site> <url> http://www.sulamacademy.com/AddMsgForum.asp?FType=273171&SBLang=0&WSUAccess=0&LocSBID=20375 </url> </site> <site> <url> http://www.wow.co.il </url> </site> <site> <url> http://www.Google.co.il </url> </site> I made this script to read the data from him, and put in on the html file. function LoadXML() { var ajaxObj = new XMLHttpRequest(); ajaxObj.open('GET', 'Sites.xml', false); ajaxObj.send(); var myXML = ajaxObj.responseXML; document.write('<table border="2">'); var prs = myXML.getElementsByTagName("site"); for (i = 0; i < prs.length; i++) { document.write("<tr><td>"); document.write(prs[i].getElementsByName("url")[0].childNode[0].nodeValue); document.write("</td></tr>"); } document.write("</table"); }

  • Managing web.config for teams in VS2010 & TFS

    - by Jarrett
    With VS2010's mandate that web.config be included in the project, how do we allow everyone to keep their own custom config file without getting into source control problems? Previously, we would simply leave web.config out of our project, allowing everyone to keep their own local version of web.config on their machine. We moved to VS2010, and it is now forcing me to add web.config to my project in order to run debug mode. Because our project is linked to TFS, it automatically adds web.config to source control and tries to maintain it that way. Is there a way to run in debug mode without including web.config in your project? Or is there a better way to manage config files?

  • Insertions into Zipper trees on XML files in Clojure

    - by ivar
    I'm confused as how to idiomatically change a xml tree accessed through clojure.contrib's zip-filter.xml. Should be trying to do this at all, or is there a better way? Say that I have some dummy xml file "itemdb.xml" like this: <itemlist> <item id="1"> <name>John</name> <desc>Works near here.</desc> </item> <item id="2"> <name>Sally</name> <desc>Owner of pet store.</desc> </item> </itemlist> And I have some code: (require '[clojure.zip :as zip] '[clojure.contrib.duck-streams :as ds] '[clojure.contrib.lazy-xml :as lxml] '[clojure.contrib.zip-filter.xml :as zf]) (def db (ref (zip/xml-zip (lxml/parse-trim (java.io.File. "itemdb.xml"))))) ;; Test that we can traverse and parse. (doall (map #(print (format "%10s: %s\n" (apply str (zf/xml-> % :name zf/text)) (apply str (zf/xml-> % :desc zf/text)))) (zf/xml-> @db :item))) ;; I assume something like this is needed to make the xml tags (defn create-item [name desc] {:tag :item :attrs {:id "3"} :contents (list {:tag :name :attrs {} :contents (list name)} {:tag :desc :attrs {} :contents (list desc)})}) (def fred-item (create-item "Fred" "Green-haired astrophysicist.")) ;; This disturbs the structure somehow (defn append-item [xmldb item] (zip/insert-right (-> xmldb zip/down zip/rightmost) item)) ;; I want to do something more like this (defn append-item2 [xmldb item] (zip/insert-right (zip/rightmost (zf/xml-> xmldb :item)) item)) (dosync (alter db append-item2 fred-item)) ;; Save this simple xml file with some added stuff. (ds/spit "appended-itemdb.xml" (with-out-str (lxml/emit (zip/root @db) :pad true))) I am unclear about how to use the clojure.zip functions appropriately in this case, and how that interacts with zip-filter. If you spot anything particularly weird in this small example, please point it out.
