  • Why doesn't JSF 2.0 RI (Mojarra) scan my class' annotations?

    - by DWoldrich
    I have a War and Jar project in my Eclipse-based JSF project. I have decided to use annotations to declare my FacesConverter, (among a myriad other things), rather than declare it using my faces-config.xml. @FacesConverter(value="passwordFieldStringConverter") public class PasswordFieldStringConverter implements Converter { public Object getAsObject(FacesContext arg0, UIComponent arg1, String arg2) throws ConverterException { try { return arg2.getBytes("UTF-16BE"); } catch(UnsupportedEncodingException uee) { Assert.impossibleException(uee); } return(null); } public String getAsString(FacesContext arg0, UIComponent arg1, Object arg2) throws ConverterException { try { return new String((byte[]) arg2, "UTF-16BE"); } catch(UnsupportedEncodingException uee) { Assert.impossibleException(uee); } return(null); } } And then I use passwordFieldStringConverter directly in my .xhtml: <?xml version="1.0" encoding="UTF-8" ?> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:f="http://java.sun.com/jsf/core" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:sec="http://www.springframework.org/security/facelets/tags"> <ui:composition> <f:view> <f:loadBundle basename="landingPage.bundle" var="bundle" /> <ui:decorate template="/WEB-INF/jsf_helpers/htmlShell.xhtml"> <ui:param name="PageTitleParam" value="#{bundle.pageTitle}" /> <h:form> <h:dataTable var="rowVar" value="#{userListContainer.users}"> <f:facet name="header"><h:outputText value="Users you are currently managing:" /></f:facet> <h:column> <f:facet name="header"> <h:outputText value="Screen Name" /> </f:facet> <h:outputText value="#{rowVar.screenName}" /> </h:column> <h:column> <f:facet name="header"> <h:outputText value="Password" /> </f:facet> <h:outputText value="#{rowVar.password}"> <f:converter converterId="passwordFieldStringConverter" /> </h:outputText> </h:column> </h:dataTable> </h:form> </ui:decorate> </f:view> </ui:composition> </html> JSF is supposed to scan the jars in my War at deployment-time and detect which classes have annotations on them (and auto-configure the application accordingly). My problem is that JSF is apparently not detecting the classes I have which sport annotations. The War project has all of my .xhtml files as well as the project's faces-config.xml, my Jar project has all of my faces related Java code (action beans, managed beans, custom converters, etc.)

  • Model binding nested collections in ASP.NET MVC

    - by MartinHN
    Hi I'm using Steve Sanderson's BeginCollectionItem helper with ASP.NET MVC 2 to model bind a collection if items. That works fine, as long as the Model of the collection items does not contain another collection. I have a model like this: -Product --Variants ---IncludedAttributes Whenever I render and model bind the Variants collection, it works jusst fine. But with the IncludedAttributes collection, I cannot use the BeginCollectionItem helper because the id and names value won't honor the id and names value that was produced for it's parent Variant: <div class="variant"> <input type="hidden" value="bbd4fdd4-fa22-49f9-8a5e-3ff7e2942126" autocomplete="off" name="Variants.index"> <input type="hidden" value="0" name="Variants[bbd4fdd4-fa22-49f9-8a5e-3ff7e2942126].SlotAmount" id="Variants_bbd4fdd4-fa22-49f9-8a5e-3ff7e2942126__SlotAmount"> <table class="included-attributes"> <input type="hidden" value="0" name="Variants.IncludedAttributes[c5989db5-b1e1-485b-b09d-a9e50dd1d2cb].Id" id="Variants_IncludedAttributes_c5989db5-b1e1-485b-b09d-a9e50dd1d2cb__Id" class="attribute-id"> <tr> <td> <input type="hidden" value="0" name="Variants.IncludedAttributes[c5989db5-b1e1-485b-b09d-a9e50dd1d2cb].Id" id="Variants_IncludedAttributes_c5989db5-b1e1-485b-b09d-a9e50dd1d2cb__Id" class="attribute-id"> </td> </tr> </table> </div> If you look at the name of the first hidden field inside the table, it is Variants.IncludedAttributes - where it should have been Variants[bbd4fdd4-fa22-49f9-8a5e-3ff7e2942126].IncludedAttributes[...]... That is because when I call BeginCollectionItem the second time (On the IncludedAttributes collection) there's given no information about the item index value of it's parent Variant. My code for rendering a Variant looks like this: <div class="product-variant round-content-box grid_6" data-id="<%: Model.AttributeType.Id %>"> <h2><%: Model.AttributeType.AttributeTypeName %></h2> <div class="box-content"> <% using (Html.BeginCollectionItem("Variants")) { %> <div class="slot-amount"> <label class="inline" for="slotAmountSelectList"><%: Text.amountOfThisVariant %>:</label> <select id="slotAmountSelectList"><option value="1">1</option><option value="2">2</option></select> </div> <div class="add-values"> <label class="inline" for="txtProductAttributeSearch"><%: Text.addVariantItems %>:</label> <input type="text" id="txtProductAttributeSearch" class="product-attribute-search" /><span><%: Text.or %> <a class="select-from-list-link" href="#select-from-list" data-id="<%: Model.AttributeType.Id %>"><%: Text.selectFromList.ToLowerInvariant() %></a></span> <div class="clear"></div> </div> <%: Html.HiddenFor(m=>m.SlotAmount) %> <div class="included-attributes"> <table> <thead> <tr> <th><%: Text.name %></th> <th style="width: 80px;"><%: Text.price %></th> <th><%: Text.shipping %></th> <th style="width: 90px;"><%: Text.image %></th> </tr> </thead> <tbody> <% for (int i = 0; i < Model.IncludedAttributes.Count; i++) { %> <tr><%: Html.EditorFor(m => m.IncludedAttributes[i]) %></tr> <% } %> </tbody> </table> </div> <% } %> </div> </div> And the code for rendering an IncludedAttribute: <% using (Html.BeginCollectionItem("Variants.IncludedAttributes")) { %> <td> <%: Model.AttributeName %> <%: Html.HiddenFor(m => m.Id, new { @class = "attribute-id" })%> <%: Html.HiddenFor(m => m.ProductAttributeTypeId) %> </td> <td><%: Model.Price.ToCurrencyString() %></td> <td><%: Html.DropDownListFor(m => m.RequiredShippingTypeId, AppData.GetShippingTypesSelectListItems(Model.RequiredShippingTypeId)) %></td> <td><%: Model.ImageId %></td> <% } %>

  • I am getting an error with a oneToMany association when using annotations with gilead for hibernate

    - by user286630
    Hello Guys I'm using Gilead to persist my entities in my GWT project, im using hibernate annotations aswell. my problem is on my onetomany association.this is my User class that holds a reference to a list of FileLocations @Entity @Table(name = "yf_user_table") public class YFUser implements Serializable { @Id @GeneratedValue(strategy = GenerationType.AUTO) @Column(name = "user_id",nullable = false) private int userId; @Column(name = "username") private String username; @Column(name = "password") private String password; @Column(name = "email") private String email; @OneToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY) @JoinColumn(name="USER_ID") private List fileLocations = new ArrayList(); This is my file location class @Entity @Table(name = "fileLocationTable") public class FileLocation implements Serializable { @Id @GeneratedValue(strategy = GenerationType.AUTO) @Column(name = "locationId", updatable = false, nullable = false) private int ieId; @Column (name = "location") private String location; @ManyToOne(fetch=FetchType.LAZY) @JoinColumn(name="USER_ID", nullable=false) private YFUser uploadedUser; When i persist this data in a normal desktop application, it works fine , creates the tables and i can add and store data to it. but when i try to persist the data in my gwt application i get errors i will show them lower. this is my ServiceImpl class that extends PersistentRemoteService. public class TestServiceImpl extends PersistentRemoteService implements TestService { public static final String SESSION_USER = "UserWithinSession"; public TestServiceImpl(){ HibernateUtil util = new HibernateUtil(); util.setSessionFactory(com.example.server.HibernateUtil .getSessionFactory()); PersistentBeanManager pbm = new PersistentBeanManager(); pbm.setPersistenceUtil(util); pbm.setProxyStore(new StatelessProxyStore()); setBeanManager(pbm); } @Override public String registerUser(String username, String password, String email) { Session session = com.example.server.HibernateUtil.getSessionFactory().getCurrentSession(); session.beginTransaction(); YFUser newUser = new YFUser(); newUser.setUsername(username);newUser.setPassword(password);newUser.setEmail(email); session.save(newUser); session.getTransaction().commit(); return "Thank you For registering "+ username; } this is the error that im am getting. the error goes away when i remove my onetoManyRelationship and builds my session factory when i put it in , it on the line of buildsessionfactory in hibernate Util that it throws this exception. my hibernate util class is ok also. this is the error java.lang.NoSuchMethodError: javax.persistence.OneToMany.orphanRemoval()Z Mar 24, 2010 10:03:22 PM org.hibernate.cfg.annotations.Version <clinit> INFO: Hibernate Annotations 3.5.0-Beta-4 Mar 24, 2010 10:03:22 PM org.hibernate.cfg.Environment <clinit> INFO: Hibernate 3.5.0-Beta-4 Mar 24, 2010 10:03:22 PM org.hibernate.cfg.Environment <clinit> INFO: hibernate.properties not found Mar 24, 2010 10:03:22 PM org.hibernate.cfg.Environment buildBytecodeProvider INFO: Bytecode provider name : javassist Mar 24, 2010 10:03:22 PM org.hibernate.cfg.Environment <clinit> INFO: using JDK 1.4 java.sql.Timestamp handling Mar 24, 2010 10:03:22 PM org.hibernate.annotations.common.Version <clinit> INFO: Hibernate Commons Annotations 3.2.0-SNAPSHOT Mar 24, 2010 10:03:22 PM org.hibernate.cfg.Configuration configure INFO: configuring from resource: /hibernate.cfg.xml Mar 24, 2010 10:03:22 PM org.hibernate.cfg.Configuration getConfigurationInputStream INFO: Configuration resource: /hibernate.cfg.xml Mar 24, 2010 10:03:22 PM org.hibernate.cfg.Configuration doConfigure INFO: Configured SessionFactory: null Mar 24, 2010 10:03:22 PM org.hibernate.cfg.search.HibernateSearchEventListenerRegister enableHibernateSearch INFO: Unable to find org.hibernate.search.event.FullTextIndexEventListener on the classpath.

  • How to write Haskell function to verify parentheses matching?

    - by Rizo
    I need to write a function par :: String -> Bool to verify if a given string with parentheses is matching using stack module. Ex: par "(((()[()])))" = True par "((]())" = False Here's my stack module implementation: module Stack (Stack, push, pop, top, empty, isEmpty) where data Stack a = Stk [a] deriving (Show) push :: a -> Stack a -> Stack a push x (Stk xs) = Stk (x:xs) pop :: Stack a -> Stack a pop (Stk (_:xs)) = Stk xs pop _ = error "Stack.pop: empty stack" top :: Stack a -> a top (Stk (x:_)) = x top _ = error "Stack.top: empty stack" empty :: Stack a empty = Stk [] isEmpty :: Stack a -> Bool isEmpty (Stk [])= True isEmpty (Stk _) = False So I need to implement a 'par' function that would test a string of parentheses and say if parentheses in it matches or not. How can I do that using a stack?

  • IWebBrowser2.Navigate opens second window

    - by Sam Barham
    The following code, on Vista with Internet Explorer 7, opens two windows (the one I create, and then a second one when Navigate is called, which is the one that the file appears in). This doesn't happen in Internet Explorer 8, or on XP as far as I know. Any idea how I can stop it doing that? SHDocVw.InternetExplorerClass ieObject = (SHDocVw.InternetExplorerClass)this.ieObject; if (this.ieObject == null) { ieObject = new SHDocVw.InternetExplorerClass(); this.ieObject = ieObject; } SHDocVw.IWebBrowser2 browserApp = (SHDocVw.IWebBrowser2)this.ieObject; object empty = System.Reflection.Missing.Value; browserApp.Visible = true; User32.SetForegroundWindow(new IntPtr(browserApp.HWND)); browserApp.Navigate(filePath, ref empty, ref empty, ref empty, ref empty);

  • JQuery tablesorter - Keeping grouped subheaders together, but still sorted

    - by hfidgen
    Hiya, I'm not really a Javascript programmer, so I'm struggling with this! I'm using the tablesorter plugin along with the Tablegroup plugin, which work very nicely to group the table rows by a parent, and then sort the parents. My problem is though, that I'd also like the child rows to be sorted whilst within the parent group I've done my best to get this working but I'm afraid I've hit a wall. Can anyone suggest a new starter for 10? The example below is working fine - There are 2x groups here: Nordics (Norway and Denmark) DACH (Germany and Austria) If I click on the header row, the groups are sorted, but the child rows within the group are not sorted. <script type="text/javascript"> $(document).ready(function () { $(".tablesorter") .tablesorter({ // set default sort column sortList: [[0,0]], // don't sort by first column headers: {0: {sorter: false}} , onRenderHeader: function (){ this.wrapInner("<span></span>"); } , debug: true }) }); </script> <table id="results-header" class="grid tablesorter table-header" cellpadding="0" cellspacing="0" border="0"> <thead> <tr class="title"> <th class="countries">&nbsp;</th> <th>% market share</th> <th>% increase in mkt share</th> <th>Target achieved</th> <th>% targets</th> <th>% sales inc.

  • std::basic_stringstream<unsigned char> won't compile with MSVC 10

    - by Michael J
    I'm trying to get UTF-8 chars to co-exist with ANSI 8-bit chars. My strategy has been to represent utf-8 chars as unsigned char so that appropriate overloads of functions can be used for the two character types. e.g. namespace MyStuff { typedef uchar utf8_t; typedef std::basic_string<utf8_t> U8string; } void SomeFunc(std::string &s); void SomeFunc(std::wstring &s); void SomeFunc(MyStuff::U8string &s); This all works pretty well until I try to use a stringstream. std::basic_ostringstream<MyStuff::utf8_t> ostr; ostr << 1; MSVC Visual C++ Express V10 won't compile this: c:\program files\microsoft visual studio 10.0\vc\include\xlocmon(213): warning C4273: 'id' : inconsistent dll linkage c:\program files\microsoft visual studio 10.0\vc\include\xlocnum(65) : see previous definition of 'public: static std::locale::id std::numpunct<unsigned char>::id' c:\program files\microsoft visual studio 10.0\vc\include\xlocnum(65) : while compiling class template static data member 'std::locale::id std::numpunct<_Elem>::id' with [ _Elem=Tk::utf8_t ] c:\program files\microsoft visual studio 10.0\vc\include\xlocnum(1149) : see reference to function template instantiation 'const _Facet &std::use_facet<std::numpunct<_Elem>>(const std::locale &)' being compiled with [ _Facet=std::numpunct<Tk::utf8_t>, _Elem=Tk::utf8_t ] c:\program files\microsoft visual studio 10.0\vc\include\xlocnum(1143) : while compiling class template member function 'std::ostreambuf_iterator<_Elem,_Traits> std::num_put<_Elem,_OutIt>:: do_put(_OutIt,std::ios_base &,_Elem,std::_Bool) const' with [ _Elem=Tk::utf8_t, _Traits=std::char_traits<Tk::utf8_t>, _OutIt=std::ostreambuf_iterator<Tk::utf8_t,std::char_traits<Tk::utf8_t>> ] c:\program files\microsoft visual studio 10.0\vc\include\ostream(295) : see reference to class template instantiation 'std::num_put<_Elem,_OutIt>' being compiled with [ _Elem=Tk::utf8_t, _OutIt=std::ostreambuf_iterator<Tk::utf8_t,std::char_traits<Tk::utf8_t>> ] c:\program files\microsoft visual studio 10.0\vc\include\ostream(281) : while compiling class template member function 'std::basic_ostream<_Elem,_Traits> & std::basic_ostream<_Elem,_Traits>::operator <<(int)' with [ _Elem=Tk::utf8_t, _Traits=std::char_traits<Tk::utf8_t> ] c:\program files\microsoft visual studio 10.0\vc\include\sstream(526) : see reference to class template instantiation 'std::basic_ostream<_Elem,_Traits>' being compiled with [ _Elem=Tk::utf8_t, _Traits=std::char_traits<Tk::utf8_t> ] c:\users\michael\dvl\tmp\console\console.cpp(23) : see reference to class template instantiation 'std::basic_ostringstream<_Elem,_Traits,_Alloc>' being compiled with [ _Elem=Tk::utf8_t, _Traits=std::char_traits<Tk::utf8_t>, _Alloc=std::allocator<uchar> ] . c:\program files\microsoft visual studio 10.0\vc\include\xlocmon(213): error C2491: 'std::numpunct<_Elem>::id' : definition of dllimport static data member not allowed with [ _Elem=Tk::utf8_t ] Any ideas? ** Edited 19 June 2012 ** OK, I've gotten closer to understanding this, but not how to solve it. As we all know, static class variables get defined twice: once in the class definition and once outside the class definition which establishes storage space. e.g. // in .h file class CFoo { // ... static int x; }; // in .cpp file int CFoo::x = 42; Now in the VC10 headers we get something like this: template<class _Elem> class numpunct : public locale::facet { // ... _CRTIMP2_PURE static locale::id id; // ... } When the header is included in an application, _CRTIMP2_PURE is defined as __declspec(dllimport), which means that the variable is imported from a dll. Now the header also contains the following template<class _Elem> locale::id numpunct<_Elem>::id; Note the absence of the __declspec(dllimport) qualifier. i.e. The class declaration says that the static linkage of the id variable is in the dll, but for the general case, it gets declared outside the dll. For the known cases, there are specialisations. template locale::id numpunct<char>::id; template locale::id numpunct<wchar_t>::id; These are protected by #ifs so that they are only included when building the DLL. They are excluded otherwise. i.e. the char and wchar_t versions of numpunct ARE inside the dll So we have the class definition saying that id's storage is in the DLL, but that is only true for the char and wchar_t specialisations, meaning that my unsigned char version is doomed. :-( The only way forward that I can think of is to create my own specialisation: basically copying it from the header file and fixing it. This raises many issues. Anybody have a better idea?

  • Wicket testing - AnnotApplicationContextMock - There is no application attached to current thread ma

    I've written a couple of tests for a small web app, but I get an error when I try to run the page specific tests that makes use of WicketTester.

  • jQuery show hide divs on radio buttons

    - by RyanP13
    I have got a group of radio buttons that when clicked need to display a corresponding unordered list. I have got as far as showing the correct list according to which radio button is clicked but cannot figure out how to hide the other lists that need to be hidden. So if i click the second benefits radion then the second 'spend' ul will display and the other 'spend' uls will hide. This is my jQuery: // hide all except first ul $('div.chevron ul').not(':first').hide(); // $('div.chevron > ul > li > input[name=benefits]').live('click',function() { // work out which radio has been clicked var $radioClick = $(this).index('div.chevron > ul > li > input[name=benefits]'); var $radioClick = $radioClick + 1; $('div.chevron > ul').eq($radioClick).show(); }); // trigger click event to show spend list var $defaultRadio = $('div.chevron > ul > li > input:first[name=benefits]') $defaultRadio.trigger('click'); And this is my HTML: <div class="divider chevron"> <ul> <li><strong>What benefit are you most interested in?</strong></li> <li> <input type="radio" class="inlineSpace" name="benefits" id="firstBenefit" value="Dental" checked="checked" /> <label for="firstBenefit">Dental</label> </li> <li> <input type="radio" class="inlineSpace" name="benefits" id="secondBenefit" value="Optical" /> <label for="secondBenefit">Optical</label> </li> <li> <input type="radio" class="inlineSpace" name="benefits" id="thirdBenefit" value="Physiotherapy" /> <label for="thirdBenefit">Physiotherapy, osteopathy, chiropractic, acupuncture</label> </li> </ul> <ul> <li><strong>How much do you spend a year on Dental?</strong></li> <li> <input type="radio" class="inlineSpace" name="spend" id="rate1a" value="£50" /> <label for="rate1a">&pound;50</label> </li> <li> <input type="radio" class="inlineSpace" name="spend" id="rate2a" value="£100" /> <label for="rate2a">&pound;100</label> </li> <li> <input type="radio" class="inlineSpace" name="spend" id="rate3a" value="£150" /> <label for="rate3a">&pound;150</label> </li> </ul> <ul> <li><strong>How much do you spend a year on Optical?</strong></li> <li> <input type="radio" class="inlineSpace" name="spend" id="rate1b" value="£50" /> <label for="rate1a">&pound;50</label> </li> <li> <input type="radio" class="inlineSpace" name="spend" id="rate2b" value="£100" /> <label for="rate2a">&pound;100</label> </li> <li> <input type="radio" class="inlineSpace" name="spend" id="rate3b" value="£150" /> <label for="rate3a">&pound;150</label> </li> </ul> <ul> <li><strong>How much do you spend a year on Physiotherapy, osteopathy, chiropractic, acupuncture?</strong></li> <li> <input type="radio" class="inlineSpace" name="spend" id="rate1c" value="£50" /> <label for="rate1a">&pound;50</label> </li> <li> <input type="radio" class="inlineSpace" name="spend" id="rate2c" value="£100" /> <label for="rate2a">&pound;100</label> </li> <li> <input type="radio" class="inlineSpace" name="spend" id="rate3c" value="£150" /> <label for="rate3a">&pound;150</label> </li> </ul> <label class="button"><input type="submit" value="View your quote" class="submit" /></label> </div> I tried using: $('div.chevron > ul').not($radioClick).hide(); But that yielded a bad result where all the lists where hidden. Thanks in advance.

  • jQuery to PHP: no input... kinda

    - by Seva Alekseyev
    Hi all, I'm using jQuery to post HTTP requests to my PHP page (Apache/Linux, if that matters). I carefully validate on the client so that empty requests are not sent. However on occasions, I'd get an empty request like this: - $_POST collection empty ($_GET collection also empty); - Content-Length is nonzero (a number below 100, consistent with a valid POST from my script) - Content-Type properly application/x-www-form-urlencoded - reading from php://input yields an empty string It's as if $_POST is somehow eaten on the way. I checked the code very carefully - I don't do anything to the contents of $_POST. Any ideas, please?

  • Trying to get these list items to display inline

    I have several unordered lists that I want to display like this: <ul> <li><img></li> <li><p></li> //inline </ul> //linebreak <ul> <li><img></li> <li><p></li> //inline </ul> ...etc I'm not able to get the li items to be inline with eachother. They are stacking vertically. I have stripped away most styling but still can't figure out what I'm doing wrong: html: <ul class="instrument"> <li class="imagebox"><img src="/images/matepe.jpg" width="247" height="228" alt="Matepe" /></li> <li class="textbox"><p>The matepe is a 24 key instrument that is played by the Kore-Kore people in North-Eastern Zimbabwe and Mozambique. It utilizes four fingers-each playing an individual melody. These melodies also interwieve to create resultant melodies that can be manipulated thru accenting different fingers. The matepe is used in Rattletree as the bridge from the physical world to the spirit world. The matepe is used in the Kore-Kore culture to summon the Mhondoro spirits which are thought to be able to communicate directly with Mwari (God) without the need of an intermediary.</p></li> </ul> <ul class="instrument"> <li class="imagebox"><img src="/images/soprano_little.jpg" border="0" width="247" height="170" alt="Soprano" /></li> <li class="textbox"><p>The highest voice of the Rattletree Marimba orchestra is the Soprano marimba. The soprano is used to whip up the energy on the dancefloor and help people reach ecstatic state with it's high and clear singing voice.

It is played by standing on a platform and struck with mallets that have lacross-ball size heads (they are actually made with rubber dog balls).

  • Binary Search Tree node removal

    - by doc
    I've been trying to implement a delete function for a Binary Search Tree but haven't been able to get it to work in all cases. This is my latest attempt: if(t->get_left() == empty) *t = *t->get_left(); else if(t->get_right() == empty) *t = *t->get_right(); else if((t->get_left() != empty) && (t->get_right() != empty)) { Node* node = new Node(t->get_data(), t->get_parent(), t->get_colour(), t->get_left(), t->get_right()); *t = *node; } t is a node and empty is just a node with nothing in it. I'm just trying to swap the values but I'm getting a runtime error. Any ideas? Thanks

  • Problem with GCC calling static templates functions in templated parent class.

    - by Adisak
    I have some code that compiles and runs on MSVC++ but will not compile on GCC. I have made a test snippet that follows. My goal was to move the static method from BFSMask to BFSMaskSized. Can someone explain what is going on with the errors (esp. the weird 'operator<' error)? Thank you. In the case of both #defines are 0, then the code compiles on GCC. #define DOESNT_COMPILE_WITH_GCC 0 #define FUNCTION_IN_PARENT 0 I get errors if I change either #define to 1.

  • velocity: join optional fields with a separator/prefix

    - by SlowStrider
    What would be the most concise/readable way in a velocity template to join multiple fields with a separator while leaving out empty or null Strings without adding excess separators? As an example we have a tooltip or appointments that goes like: Appointment ($number) [with $employee] [-] [$remarks] [-] [$roomToVisit] Where I used brackets to indicate optional data. When filled in it would normally show as Appointment (3) with John - ballroom - serve Java coffee When $remarks is empty but $roomToVisit is not, this becomes: Appointment (3) with John - ballroom When $remarks is "serve Java coffee" but $roomToVisit is empty we get: Appointment (3) with John - serve Java coffee When both are empty: Appointment (3) with John Bonus: also make the field prefix optional. When only $employee is empty we should get: Appointment (2) serve Java coffee - ballroom Ideally I would like the velocity template to look very similar to the first code box. If this is not possible, how would you achieve this with a minimum of distracting code tags? Similar ideas (first is much more verbose): Join with intelligent separators velocity: do something except in last loop iteration

  • when text changed inputbox automatically updates next text boxes?

    - by James123
    Extension to my previous question http://bit.ly/c5yiVM I have 7 textboxes. If Top 1 textbox(Volume All Years) text changed, text need to be updated in next 6 inputboxes(Latest 2009 Volume to Latest 2014 Volume). I need javascript or Jquery for this. I will write Js textchanged() or focuschange() for top 1 textbox. So what should I write in focuschage() or textchanged methods(). I changed little bit in code. Now Html will like below. These textboxes have common CssClass. volumetextbox. Can we use this class and change text in all textboxes those have same CssClass. <tr id="row12_136" class="RegText"> <td style="width:420px;Padding-right:20px;">Volume All Years</td> <td style="width:420px;Padding-left:0px;"> <input name="12_136" type="text" maxlength="255" id="12_136" tabindex="61" title="Volume All Years" class="volumetextbox" OnKeyPress="javascript:FocusChange();" style="width:300px;" /> </td> <tr id="row12_60" class="RegText"> <td style="width:420px;Padding-right:20px;">Latest 2009 Volume</td> <td style="width:420px;Padding-left:0px;"> <input name="12_136" type="text" maxlength="255" id="12_60" tabindex="56" title="Volume All Years" class="volumetextbox" OnKeyPress="javascript:FocusChange();" style="width:300px;" /> </td> <tr id="row12_61" class="RegText"> <td style="width:420px;Padding-right:20px;">Latest 2010 Volume</td> <td style="width:420px;Padding-left:0px;"> <input name="12_136" type="text" maxlength="255" id="12_61" tabindex="57" title="Volume All Years" class="volumetextbox" OnKeyPress="javascript:FocusChange();" style="width:300px;" /> </td> <tr id="row12_62" class="RegText"> <td style="width:420px;Padding-right:20px;">Latest 2011 Volume</td> <td style="width:420px;Padding-left:0px;"> <input name="12_136" type="text" maxlength="255" id="12_62" tabindex="58" title="Volume All Years" class="volumetextbox" OnKeyPress="javascript:FocusChange();" style="width:300px;" /> </td> <tr id="row12_63" class="RegText"> <td style="width:420px;Padding-right:20px;">Latest 2012 Volume</td> <td style="width:420px;Padding-left:0px;"> <input name="12_136" type="text" maxlength="255" id="12_63" tabindex="59" title="Volume All Years" class="volumetextbox" OnKeyPress="javascript:FocusChange();" style="width:300px;" /> </td> <tr id="row12_64" class="RegText"> <td style="width:420px;Padding-right:20px;">Latest 2013 Volume</td> <td style="width:420px;Padding-left:0px;"> <input name="12_136" type="text" maxlength="255" id="12_64" tabindex="60" title="Volume All Years" class="volumetextbox" OnKeyPress="javascript:FocusChange();" style="width:300px;" /> </td> <tr id="row12_65" class="RegText"> <td style="width:420px;Padding-right:20px;">Latest 2014 Volume</td> <td style="width:420px;Padding-left:0px;"> <input name="12_136" type="text" maxlength="255" id="12_65" tabindex="61" title="Volume All Years" class="volumetextbox" OnKeyPress="javascript:FocusChange();" style="width:300px;" /> </td>

  • C#: Adding Functionality to 3rd Party Libraries With Extension Methods

    - by James Michael Hare
    Ever have one of those third party libraries that you love but it's missing that one feature or one piece of syntactical candy that would make it so much more useful?  This, I truly think, is one of the best uses of extension methods.  I began discussing extension methods in my last post (which you find here) where I expounded upon what I thought were some rules of thumb for using extension methods correctly.  As long as you keep in line with those (or similar) rules, they can often be useful for adding that little extra functionality or syntactical simplification for a library that you have little or no control over. Oh sure, you could take an open source project, download the source and add the methods you want, but then every time the library is updated you have to re-add your changes, which can be cumbersome and error prone.  And yes, you could possibly extend a class in a third party library and override features, but that's only if the class is not sealed, static, or constructed via factories. This is the perfect place to use an extension method!  And the best part is, you and your development team don't need to change anything!  Simply add the using for the namespace the extensions are in! So let's consider this example.  I love log4net!  Of all the logging libraries I've played with, it, to me, is one of the most flexible and configurable logging libraries and it performs great.  But this isn't about log4net, well, not directly.  So why would I want to add functionality?  Well, it's missing one thing I really want in the ILog interface: ability to specify logging level at runtime. For example, let's say I declare my ILog instance like so:     using log4net;     public class LoggingTest     {         private static readonly ILog _log = LogManager.GetLogger(typeof(LoggingTest));         ...     }     If you don't know log4net, the details aren't important, just to show that the field _log is the logger I have gotten from log4net. So now that I have that, I can log to it like so:     _log.Debug("This is the lowest level of logging and just for debugging output.");     _log.Info("This is an informational message.  Usual normal operation events.");     _log.Warn("This is a warning, something suspect but not necessarily wrong.");     _log.Error("This is an error, some sort of processing problem has happened.");     _log.Fatal("Fatals usually indicate the program is dying hideously."); And there's many flavors of each of these to log using string formatting, to log exceptions, etc.  But one thing there isn't: the ability to easily choose the logging level at runtime.  Notice, the logging levels above are chosen at compile time.  Of course, you could do some fun stuff with lambdas and wrap it, but that would obscure the simplicity of the interface.  And yes there is a Logger property you can dive down into where you can specify a Level, but the Level properties don't really match the ILog interface exactly and then you have to manually build a LogEvent and... well, it gets messy.  I want something simple and sexy so I can say:     _log.Log(someLevel, "This will be logged at whatever level I choose at runtime!");     Now, some purists out there might say you should always know what level you want to log at, and for the most part I agree with them.  For the most party the ILog interface satisfies 99% of my needs.  In fact, for most application logging yes you do always know the level you will be logging at, but when writing a utility class, you may not always know what level your user wants. I'll tell you, one of my favorite things is to write reusable components.  If I had my druthers I'd write framework libraries and shared components all day!  And being able to easily log at a runtime-chosen level is a big need for me.  After all, if I want my code to really be re-usable, I shouldn't force a user to deal with the logging level I choose. One of my favorite uses for this is in Interceptors -- I'll describe Interceptors in my next post and some of my favorites -- for now just know that an Interceptor wraps a class and allows you to add functionality to an existing method without changing it's signature.  At the risk of over-simplifying, it's a very generic implementation of the Decorator design pattern. So, say for example that you were writing an Interceptor that would time method calls and emit a log message if the method call execution time took beyond a certain threshold of time.  For instance, maybe if your database calls take more than 5,000 ms, you want to log a warning.  Or if a web method call takes over 1,000 ms, you want to log an informational message.  This would be an excellent use of logging at a generic level. So here was my personal wish-list of requirements for my task: Be able to determine if a runtime-specified logging level is enabled. Be able to log generically at a runtime-specified logging level. Have the same look-and-feel of the existing Debug, Info, Warn, Error, and Fatal calls.    Having the ability to also determine if logging for a level is on at runtime is also important so you don't spend time building a potentially expensive logging message if that level is off.  Consider an Interceptor that may log parameters on entrance to the method.  If you choose to log those parameter at DEBUG level and if DEBUG is not on, you don't want to spend the time serializing those parameters. Now, mine may not be the most elegant solution, but it performs really well since the enum I provide all uses contiguous values -- while it's never guaranteed, contiguous switch values usually get compiled into a jump table in IL which is VERY performant - O(1) - but even if it doesn't, it's still so fast you'd never need to worry about it. So first, I need a way to let users pass in logging levels.  Sure, log4net has a Level class, but it's a class with static members and plus it provides way too many options compared to ILog interface itself -- and wouldn't perform as well in my level-check -- so I define an enum like below.     namespace Shared.Logging.Extensions     {         // enum to specify available logging levels.         public enum LoggingLevel         {             Debug,             Informational,             Warning,             Error,             Fatal         }     } Now, once I have this, writing the extension methods I need is trivial.  Once again, I would typically /// comment fully, but I'm eliminating for blogging brevity:     namespace Shared.Logging.Extensions     {         // the extension methods to add functionality to the ILog interface         public static class LogExtensions         {             // Determines if logging is enabled at a given level.             public static bool IsLogEnabled(this ILog logger, LoggingLevel level)             {                 switch (level)                 {                     case LoggingLevel.Debug:                         return logger.IsDebugEnabled;                     case LoggingLevel.Informational:                         return logger.IsInfoEnabled;                     case LoggingLevel.Warning:                         return logger.IsWarnEnabled;                     case LoggingLevel.Error:                         return logger.IsErrorEnabled;                     case LoggingLevel.Fatal:                         return logger.IsFatalEnabled;                 }                                 return false;             }             // Logs a simple message - uses same signature except adds LoggingLevel             public static void Log(this ILog logger, LoggingLevel level, object message)             {                 switch (level)                 {                     case LoggingLevel.Debug:                         logger.Debug(message);                         break;                     case LoggingLevel.Informational:                         logger.Info(message);                         break;                     case LoggingLevel.Warning:                         logger.Warn(message);                         break;                     case LoggingLevel.Error:                         logger.Error(message);                         break;                     case LoggingLevel.Fatal:                         logger.Fatal(message);                         break;                 }             }             // Logs a message and exception to the log at specified level.             public static void Log(this ILog logger, LoggingLevel level, object message, Exception exception)             {                 switch (level)                 {                     case LoggingLevel.Debug:                         logger.Debug(message, exception);                         break;                     case LoggingLevel.Informational:                         logger.Info(message, exception);                         break;                     case LoggingLevel.Warning:                         logger.Warn(message, exception);                         break;                     case LoggingLevel.Error:                         logger.Error(message, exception);                         break;                     case LoggingLevel.Fatal:                         logger.Fatal(message, exception);                         break;                 }             }             // Logs a formatted message to the log at the specified level.              public static void LogFormat(this ILog logger, LoggingLevel level, string format,                                          params object[] args)             {                 switch (level)                 {                     case LoggingLevel.Debug:                         logger.DebugFormat(format, args);                         break;                     case LoggingLevel.Informational:                         logger.InfoFormat(format, args);                         break;                     case LoggingLevel.Warning:                         logger.WarnFormat(format, args);                         break;                     case LoggingLevel.Error:                         logger.ErrorFormat(format, args);                         break;                     case LoggingLevel.Fatal:                         logger.FatalFormat(format, args);                         break;                 }             }         }     } So there it is!  I didn't have to modify the log4net source code, so if a new version comes out, i can just add the new assembly with no changes.  I didn't have to subclass and worry about developers not calling my sub-class instead of the original.  I simply provide the extension methods and it's as if the long lost extension methods were always a part of the ILog interface! Consider a very contrived example using the original interface:     // using the original ILog interface     public class DatabaseUtility     {         private static readonly ILog _log = LogManager.Create(typeof(DatabaseUtility));                 // some theoretical method to time         IDataReader Execute(string statement)         {             var timer = new System.Diagnostics.Stopwatch();                         // do DB magic                                    // this is hard-coded to warn, if want to change at runtime tough luck!             if (timer.ElapsedMilliseconds > 5000 && _log.IsWarnEnabled)             {                 _log.WarnFormat("Statement {0} took too long to execute.", statement);             }             ...         }     }     Now consider this alternate call where the logging level could be perhaps a property of the class          // using the original ILog interface     public class DatabaseUtility     {         private static readonly ILog _log = LogManager.Create(typeof(DatabaseUtility));                 // allow logging level to be specified by user of class instead         public LoggingLevel ThresholdLogLevel { get; set; }                 // some theoretical method to time         IDataReader Execute(string statement)         {             var timer = new System.Diagnostics.Stopwatch();                         // do DB magic                                    // this is hard-coded to warn, if want to change at runtime tough luck!             if (timer.ElapsedMilliseconds > 5000 && _log.IsLogEnabled(ThresholdLogLevel))             {                 _log.LogFormat(ThresholdLogLevel, "Statement {0} took too long to execute.",                     statement);             }             ...         }     } Next time, I'll show one of my favorite uses for these extension methods in an Interceptor.
