  • Ajax and sophisticated graphics in Java web-app

    - by EugeneP
    In my opinion WWW will sooner or later come to full-blown AJAX web-sites, so that we wouldn't have page reloads every time you click somewhere. Now I want you to ask this. What tools and frameworks can one use to make a Java Web-application running on Tomcat have AJAX functionality like "in-place, with no page reloading" table sorting by clicking on its column header, multi-tabs that enable opening at once the new screen to the user without reloading a page, saving data in the database without reloading a page, and other similar things that we do not usually see on web pages. That's all should probably be based on AJAX. But how to integrate this AJAX functionality with existing java web-frameworks, let's say Spring MVC? Or maybe there are other frameworks that better suit such needs but that can be integrated with core Spring?

    Hello, I am using richfaces dropDownMenu component which contains a set of rich menuItems. When the menu items are displayed, a extra space is displayed before the lablel for each of the menu item.

  • How can a servlet always perform the same task?

    - by membersound
    I want a Servlet to perform always the same tasks. Regardless of if it is a GET or POST. At the moment I just call the doGet() from doPost(), which works fine. Then I tried overriding the service() method, and I thought it would just work the same way. But it does not! The code somehow gets executed, but the response does not generate the webpage: response.getWriter(); response.println(string); This code works for the doGet/doPost methods, but not for the service. Why? Servlet: class MyWebServlet extends HttpServlet { @Override public void service(ServletRequest request, ServletResponse response) { response.setContentType("text/html"); PrintWriter out = response.getWriter(); String string = "teststring"; out.println(string); } }

  • Setting date from selectInputDate to object

    - by DD
    I have a date controller which does various things. Once a calendar date is set, I want to pass the value from the date controller to another bean. The problem I have is that the setPropertyActionListener gets called before the user clicks on a date. Is there a way to get the date from the selectInputDate after selection and pass to a bean? This is what I tried: <ice:selectInputDate popupDateFormat="dd-MMM-yyyy" renderAsPopup="true" value="#{dateRangeDateContoller.end}" > <f:setPropertyActionListener target="#{searchParameters.endDate}" value="#{dateRangeDateContoller.end}" /> </ice:selectInputDate>

  • [IceFaces] Why are validators of unchanged components called?

    - by bitschnau
    I have a IceFaces-form and several input fields. Let's say I have this: <ice:selectOneMenu id="accountMenu" value="#{accountController.account.aId}" validator="#{accountController.validateAccount}"> <f:selectItems id="accountItems" value="#{accountController.accountItems}" /> </ice:selectOneMenu> and this: <ice:selectOneMenu id="costumerMenu" value="#{customerController.customer.cId}" validator="#{customerController.validateCustomer"> <f:selectItems id="customerItems" value="#{customerController.customerItems}" /> </ice:selectOneMenu> If I change one value, the respective validator is called, what is fine. But also the other validator is called, which is not fine, because the user get's an irritating message to insert a value to a field he maybe was just going to pay attention to. It's like poking the user with a stick to "Hurry up now!". BAD! I thought the attribute "partialSubmit" is controlling this behaviour, so only the one DOM-part is submitted, which is affected by the user interaction, but if I declare the both components to be partially submitted, nothing changes. Still both validators are called if one component value is changed. How can I prevent the whole form from being validated until it is submitted completely?

  • h:graphicimage not working in c:foreach

    - by Muneeswaran Balasubramanian
    I have used c:forEach loop for display the list of images using h:graphicImage. But I can't display the images. I have the h:commandLink also in my page. The image have to be displayed at the time of form inititalization. But its not working. But after click the h:commandlink, the images are displayed properly. Before that it shows the image not found text (alt message). I have used h:graphicImage tag like below <c:forEach items="#{Sample.imageList}" var="images" varstatus="imageStatus"> <h:graphicimage id="image" url="#{images}" alt="Image Not Found"/> </c:forEach> What I do wrong in that and how can I achieve that?

  • Can we have a component-scoped bean in a JSF2 composite component?

    - by Pradyumna
    Hi, I was wondering how I could create "component-scoped" beans, or so-to-say, "local variables inside a composite component" that are private to the instance of the composite component, and live as long as that instance lives. Below are more details, explained with an example: Suppose there is a "calculator" component - something that allows users to type in a mathematical expression, and evaluates its value. Optionally, it also plots the associated function. I can make a composite component that has: a text box for accepting the math expression two buttons called "Evaluate", and "Plot" another nested component that plots the function It is evidently a self-contained piece of function; so that somebody who wants to use it may just say <math:expressionEvaluator /> But obviously, the implementation would need a java object - something that evaluates the expression, something that computes the plot points, etc. - and I imagine it can be a bean - scoped just for this instance of this component, not a view-scoped or request-scoped bean that is shared across all instances of the component. How do I create such a bean? Is that even possible with composite components?

  • Refactor a link and an image

    - by Mihail Stoynov
    I have to write an link with an image inside. Instead of explaining, here's the code I have now: <c:if test="${userSession.loggedUser eq null and company.image != null}"> <a onclick="${rich:component('loginPanel')}.show()"> <img src="/download.do?hash=#{company.image.hash}" /> </a> </c:if> <c:if test="${userSession.loggedUser eq null and company.image == null}"> <a onclick="${rich:component('loginPanel')}.show()"> <img src="${request.contextPath}/img/icons/logo_default.jpg" /> </a> </c:if> <c:if test="${userSession.loggedUser ne null and company.image != null}"> <a href="company.xhtml?${company.name}"> <img src="/download.do?hash=#{company.image.hash}" /> </a> </c:if> <c:if test="#{userSession.loggedUser ne null and company.image == null}"> <a href="company.xhtml?${company.name}"> <img src="${request.contextPath}/img/icons/logo_default.jpg" /> </a> </c:if> This code looks awful - there are two exact links with two exact images but combined in all possible combinations. Is there a better way? Is there a way to avoid c:if - it created tables? Update: Bozho proposes: You can replace <c:if and <a with <h:outputLink rendered="#{..}". Apart from that I don't see any other optimization. But it doesn't work. This does not render correctly: <a href=> <h:outputLink rendered="#{..} <h:outputLink rendered="#{..} </a> (the image is outside the anchor) This does render fine: <h:outputLink value=> <h:outputLink rendered="#{..} <h:outputLink rendered="#{..} </a> , but it always adds href and in two of the cases I don't want href when rendered.

  • richfaces suggestionBox passing additional values to backing bean

    - by Martlark
    When using the rich faces suggestionBox how can you pass more than one id or value from the page with the text input to the suggestionBox backing bean. ie: to show a list of suggested cities within a selected state? Here is my autoComplete method. public List< Suburb > autocomplete(Object suggest) { String pref = (String) suggest; ArrayList< Suburb > result = new ArrayList< Suburb >(); Iterator< Suburb > iterator = getSuburbs().iterator(); while( iterator.hasNext() ) { Suburb elem = ((Suburb) iterator.next()); if( (elem.getName() != null && elem.getName().toLowerCase().indexOf( pref.toLowerCase() ) == 0) || "".equals( pref ) ) { result.add( elem ); } } return result; } As you can see there is one value passed from the page, Object suggest, which is the text of the h:inputText (in the faceLets m:textFormRow ) <m:textFormRow id="suburb" label="#{msgs.suburbPrompt}" property="#{bean[dto].addressDTO.suburb}" required="true" maxlength="100" size="30" /> <rich:suggestionbox height="200" width="200" usingSuggestObjects="true" suggestionAction="#{suburbsMBean.autocomplete}" var="suburb" for="suburb" fetchValue="#{suburb.name}" id="suggestion"> <h:column> <h:outputText value="#{suburb.name}" /> </h:column> </rich:suggestionbox> Earlier in the page you can select a state which I'd like to use to pare down the list of suburbs that the suggestion box displays.

  • How hide some nodes in Richfaces Tree (do not render nodes by condition)?

    - by VestniK
    I have a tree of categories and courses in my SEAM application. Courses may be active and inactive. I want to be able to show only active or all courses in my tree. I've decided to always build complete tree in my PAGE scope component since building this tree is quite expensive operation. I have boolean flag courseActive in the data wrapped by TreeNode<T>. Now I can't find the way to show courses node only if this flag is true. The best result I've achieved with the following code: <h:outputLabel for="showInactiveCheckbox" value="show all courses: "/> <h:selectBooleanCheckbox id="showInactiveCheckbox" value="#{categoryTreeEditorModel.showAllCoursesInTree}"> <a4j:support event="onchange" reRender="categoryTree"/> </h:selectBooleanCheckbox> <rich:tree id="categoryTree" value="#{categoryTree}" var="item" switchType="ajax" ajaxSubmitSelection="true" reRender="categoryTree,controls" adviseNodeOpened="#{categoryTreeActions.adviseRootOpened}" nodeSelectListener="#{categoryTreeActions.processSelection}" nodeFace="#{item.typeName}"> <rich:treeNode type="Category" icon="..." iconLeaf="..."> <h:outputText value="#{item.title}"/> </rich:treeNode> <rich:treeNode type="Course" icon="..." iconLeaf="..." rendered="#{item.courseActive or categoryTreeEditorModel.showAllCoursesInTree}"> <h:outputText rendered="#{item.courseActive}" value="#{item.title}"/> <h:outputText rendered="#{not item.courseActive}" value="#{item.title}" style="color:#{a4jSkin.inactiveTextColor}"/> </rich:treeNode> </rich:tree> the only problem is if some node is not listed in any rich:treeNode it just still shown with title obtained by Object.toString() method insted of being hidden. Does anybody know how to not show some nodes in the Richfases tree according to some condition?

  • populate drop-down values dynamically using Ajax

    - by abhishek
    Hi, I have 3 drop-downs. 1st drop-down contains some values when the page loads. I need to populate 2 nd drop-down based on the value selected in 1st dropdown. Similarly, I need to populate 3 nd drop-down based on the value selected in 1st and 2nd dropdown. Initially I tried like this. <h:selectOneMenu value="#{stu.country}" > <f:selectItems value="#{bean.allCountries}" /> <a4j:support event="onchange" action="#{bean.retrieveStates(stu.country)}" reRender="states_dropDown"></a4j:support> </h:selectOneMenu> //ly, for 2nd drop-down <h:selectOneMenu id="states_dropDown" value="#{stu.state}" > <f:selectItems value="#{bean.allStates}" /> <a4j:support event="onchange" action="#{bean.retrieveCities(stu.country,stu.state)}" reRender="City_dropDown"></a4j:support> </h:selectOneMenu> Some times this code works fine. But some times it doesn't invoke managed bean method. Can you please help??

  • Why can't I have static public fields in my managed beans?

    - by AlanObject
    I just started using the Netbeans 7.1 beta and it is calling out errors of a type which I have never seen before. Specifically: A managed bean with a public field should not declare any scope other than @Dependent. The fields it is complaining about are public static final. I can understand the restriction on non-static fields, but I can't think of a good reason this would not be allowed for a static field. Unfortunately I use a lot of them since I don't like having constants in my code. I note that even though I get the red dot in the margin in the editor, the maven-driven build still works and GlassFish still runs my application the way I would expect. So what is my denoument on this issue? Am I going to have to move my static fields elsewhere or is there another way of handling this?

  • Does NavigationHandler.handleNavigation() clear the flash?

    - by kgrad
    I am using JSF2.0 Mojarra 2.0.2. I have a method that logs out a user and puts a logout message in the flash, forwards to the login page (which has a div that prints out the flash). However, when I use navigationHandlers handleNavigation method for some reason the flash is not being displayed. I have a similar method that forwards a user to the login page if he/she isn't logged in. If I handle the navigation through an h:link and just call the logout method directly, the flash is displayed as normal, but if I use the handleNavigation() method, the flash is cleared for some reason. The code in question is: public void performLogout() { getFacesContext().getExternalContext().invalidateSession(); setCurrentUser(null); getFlash().put("notice", "Successfully logged out."); super.getFacesContext().getApplication().getNavigationHandler() .handleNavigation(getFacesContext(), null, "login"); } Is there some way I can keep the flash when navigating like this? thanks.
