  • Chrome OS : déjà un échec pour le créateur de Gmail et de la devise de Google, l'OS accumule les critiques négatives

    Chrome OS : déjà un échec pour le créateur de Gmail et de la devise de Google L'OS accumule les critiques négatives Les premières critiques sur Chrome OS ne sont pas bonnes. Parmi ces testeurs des premiers laptops équipés de l'OS de Google orienté Cloud, deux voix portent un peu plus que les autres. Celle de Paul Buchheit, créateur de Gmail, et celle de Richard Stallman, le père du GNU. La première constatation polémique, bien qu'elle aille dans le sens de la vision de Google d'un OS totalement intégré dans le Web, a choqué plus d'un testeur de la première heure. Chrome OS n'a tout simplement pas d'explorateur de disques durs. En tout cas rien d'équivalent à Windows...

  • Computer-controlled Lights and Music Synced into Christmas Rock Spectacular

    - by Jason Fitzpatrick
    This spectacular computer controlled and synchronized lighting display combines thousands of feet of LED lighting, multiple controllers, and a rock medley to great effect. The above display started life as the personal Christmas light display of Sioux Falls, ND resident Joe Noe. When Noe moved, he donated his display to a local mall in order to preserve the tradition of people stopping by to see it and making donations to the Make-A-Wish foundation. The local mall, Western Mall, expanded the display and added in even more LEDs and controllers. The end result is an impressive display synced to a Christmas rock medley by UK musician Richard Campbell.

    Many thanks to Richard Hopton and the NxtGenUG guys in Oxford for inviting me to talk on Hyper-V for Developers last night, and for Research Machines for providing the venue.  It was great to have developers not yet using Hyper-V who were really interested in some of the finer points to help them with specific requirements. For those wanting to follow up on the topics I covered, you can download the presentation deck as either PDF (with speaker notes included) or as the original PowerPoint slidedeck,   http://www.tigernews.co.uk/blog-twickers/nxtgenugoxford/HyperV4Devs.pdf   http://www.tigernews.co.uk/blog-twickers/nxtgenugoxford/HyperV4Devs.zip I also mentioned the new feature, Dynamic Memory, coming in Service Pack 1, had been presented in a session at TechEd 2010 by Ben Armstrong, and you can download his presentation from here,   http://blogs.msdn.com/b/virtual_pc_guy/archive/2010/06/08/talking-about-dynamic-memory.aspx

  • Any suggestions how it would be good to promote software in a small company ?

    - by Derfder
    Ok, I know if I am Red hat or other giant and offer some support etc. I can be profitable, in fact, Red Hat is doing quite well. However, what about a small company where I create a small program. e.g. an instant messenger for a windows or linux (just as an illustration) and I want to sell it. But how can I sell it if it is free and everybody can download it? Any advice? I like the idea of FSF by Richard Stallman, however I am missing the way how to sell my software under GNU/GPL licence. Any advice, how can I solve this problem? Any profitable small business software developers around with their opinion? Any links or names of small companies taht I can look at and study their model of business?

  • Can not print after upgrading from 12.x to 14.04

    - by user318889
    After upgrading from V12.04 to V14.04 I am not able to print. I am using an HP LaserJet 400 M451dn. The printer troubleshooter told me that there is no solution to the problem.

  • Survey says: Java technology rules

    - by hinkmond
    Eclipse came out with their Open Source Developer Report and Survey for 2012. In it, we see (in the words of the immortal Richard Dawson, RIP) "Surveys Says!": Java computer programming language is on top. See: Java is the top Here's a quote: The Eclipse community was invited to participate in the survey between April 23 and May 15 of this year. Skerrett says the Foundation promoted the survey primarily through social media (Facebook, Twitter) and online forums. Of the 840 people who responded, 732 completed the survey... So, now we know who's on top, we can keep this in mind the next time this question comes up on Family Feud. Hinkmond

    Google a-t-il raté son entrée sur le marché des tablettes ? Android connaît une "croissance pénible" d'après DisplaySearch Six mois après le lancement d'Android 3 (alias Honeycomb), force est de constater que les ventes des tablettes qui tournent dessus sont loin de défrayer les chroniques, elles ne semblent pas être en mesure en tout cas de freiner les ventes frénétiques de l'iPad d'Apple. Pour l'analyste Richard Shim de DisplaySearch, l'univers Android connaît une « croissance pénible » avec Honeycomb : « il est clair que les premières tablettes fondées sur Android ne s'écoulent pas aussi bien que ce que beaucoup attendaient, quelques marques avec lesquelles ...

  • JSF 2.0 AJAX: jsf.ajax.request to call method not only rerender an area of page

    - by gerry
    Hi, I'm looking for a soultion of the following problem: _The is a list of links with different types of cars. _The user can click on each car in the list and a ajax request should be sent. _The response of the ajax request should be dependent on the id (of each car) and displayed in an panelGroup. So what I need is a possibility to call a method on the backing-bean. Additionally, this method should be called with a car id as its parameter. My code so far looks like: ... <ul> <ui:repeat value="#{carTree.getCars)}" var="car"> <h:outputScript name="jsf.js" library="javax.faces" target="head" /> <li onclick="showDetails(#{car.id});">#{car.name}</li> </ui:repeat> </ul> ... <h:panelGroup id="carDetails" layout="block" style="float:left;"> // need the details of each 'selected /clicked' car here </h:panelGroup> ... And the method in the backing bean should look like: public class CarTree { ... public String getCarDetails(int carid){ return "The car details for the car id "+carid+" are......"; } ... } I've no idea how to call a method by using the new JSF 2.0 AJAX functionality. Please, help me...

  • How to get selected row index in JSF datatable?

    - by Nitesh Panchal
    I have a databale on index.xhtml <h:dataTable style="border: solid 2px black;" value="#{IndexBean.bookList}" var="item" binding="#{IndexBean.datatableBooks}"> <h:column> <h:commandButton value="Edit" actionListener="#{IndexBean.editBook}"> <f:param name="index" value="#{IndexBean.datatableBooks.rowIndex}"/> </h:commandButton> </h:column> </h:dataTable> My bean: @ManagedBean(name="IndexBean") @ViewScoped public class IndexBean implements Serializable { private HtmlDataTable datatableBooks; public HtmlDataTable getDatatableBooks() { return datatableBooks; } public void setDatatableBooks(HtmlDataTable datatableBooks) { this.datatableBooks = datatableBooks; } public void editBook() throws IOException{ int index = Integer.parseInt(FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap().get("index").toString()); System.out.println(index); } } My problem is that I always get the same index in server log even though I click the different edit buttons. Imagine that there is one collection which is supplied to the datatable. I have not shown that in bean. If I change scope from ViewScope to RequestScope it works fine. What can be the problem with @ViewScoped? Thanks in advance :) EDIT: <h:column> <h:commandButton value="Edit" actionListener="#{IndexBean.editBook}" /> </h:column> public void editBook(ActionEvent ev) throws IOException{ if (ev.getSource() != null && ev.getSource() instanceof HtmlDataTable) { HtmlDataTable objHtmlDataTable = (HtmlDataTable) ev.getSource(); System.out.println(objHtmlDataTable.getRowIndex()); } }

  • spring-mvc binding arraylist in form

    - by Mike
    In my controller I added an ArrayList to my model with the attribute name "users". Now I looked around and this is the method I found (including a question here): <form:form action="../user/edit" method="post" modelAttribute="users"> <table> <c:forEach var="user" items="${users}" varStatus="counter"> <tr> <td> <form:input path="users[${counter.index}].age"/> </td> <td><button type="submit" name="updateId" id="Update" value="${user.id}">Update</button></td> </tr> </c:forEach> </table> </form:form> But when I load the JSP page I get: .springframework.beans.NotReadablePropertyException: Invalid property 'projects[0]' of bean class [java.util.ArrayList]: Bean property 'users[0]' is not readable or has an invalid getter method: Does the return type of the getter match the parameter type of the setter? So apparantely this isn't the way to go, but in that case how do I bind an arraylist so I can edit the values?

  • Spring 3 DI using generic DAO interface

    - by Peders
    I'm trying to use @Autowired annotation with my generic Dao interface like this: public interface DaoContainer<E extends DomainObject> { public int numberOfItems(); // Other methods omitted for brevity } I use this interface in my Controller in following fashion: @Configurable public class HelloWorld { @Autowired private DaoContainer<Notification> notificationContainer; @Autowired private DaoContainer<User> userContainer; // Implementation omitted for brevity } I've configured my application context with following configuration <context:spring-configured /> <context:component-scan base-package="com.organization.sample"> <context:exclude-filter expression="org.springframework.stereotype.Controller" type="annotation" /> </context:component-scan> <tx:annotation-driven /> This works only partially, since Spring creates and injects only one instance of my DaoContainer, namely DaoContainer. In other words, if I ask userContainer.numberOfItems(); I get the number of notificationContainer.numberOfItems() I've tried to use strongly typed interfaces to mark the correct implementation like this: public interface NotificationContainer extends DaoContainer<Notification> { } public interface UserContainer extends DaoContainer<User> { } And then used these interfaces like this: @Configurable public class HelloWorld { @Autowired private NotificationContainer notificationContainer; @Autowired private UserContainer userContainer; // Implementation omitted... } Sadly this fails to BeanCreationException: org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.organization.sample.dao.NotificationContainer com.organization.sample.HelloWorld.notificationContainer; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [com.organization.sample.NotificationContainer] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)} Now, I'm a little confused how should I proceed or is using multiple Dao's even possible. Any help would be greatly appreciated :)

I am getting the error as follows, org.springframework.webflow.definition.registry.NoSuchFlowDefinitionException: No flow definition '${flowExecutionUrl}&_eventId=next' found at org.springframework.webflow.definition.registry.FlowDefinitionRegistryImpl.getFlowDefinitionHolder(FlowDefinitionRegistryImpl.java:126) at org.springframework.webflow.definition.registry.FlowDefinitionRegistryImpl.getFlowDefinition(FlowDefinitionRegistryImpl.java:61) at org.springframework.webflow.executor.FlowExecutorImpl.launchExecution(FlowExecutorImpl.java:138) at org.springframework.webflow.mvc.servlet.FlowHandlerAdapter.handle(FlowHandlerAdapter.java:193).... Shown below is my configurations, <bean name="flowController" class="org.springframework.webflow.mvc.servlet.FlowController"> <property name="flowExecutor" ref="flowExecutor"></property> </bean> <webflow:flow-executor id="flowExecutor" /> <webflow:flow-registry id="flowRegistry" > <webflow:flow-location path="/WEB-INF/flows/welcome/welcome.xml"></webflow:flow-location> </webflow:flow-registry> /WEB-INF/flows/welcome/welcome.xml, <view-state id="welcome"> <transition on="next" to="introduction" /> <transition on="skip" to="menu" /> </view-state> <view-state id="introduction"> <on-render> <evaluate expression="libraryService.getHolidays()" result="requestScope.holidays" /> </on-render> <transition on="next" to="menu" /> </view-state> <view-state id="menu"></view-state> In welcome.jsp, <a href="${flowExecutionUrl}&_eventId=next">Next</a> <a href="${flowExecutionUrl}&_eventId=skip">Skip</a> Please let me know what is going wrong.

  • How to access/use custom attribute in spring security based CAS client

    - by Bill Li
    I need send certain attributes(say, human readable user name) from server to client after a successful authentication. Server part was done. Now attribute was sent to client. From log, I can see: 2010-03-28 23:48:56,669 DEBUG Cas20ServiceTicketValidator:185 - Server response: [email protected] <cas:proxyGrantingTicket>PGTIOU-1-QZgcN61oAZcunsC9aKxj-cas</cas:proxyGrantingTicket> <cas:attributes> <cas:FullName>Test account 1</cas:FullName> </cas:attributes> </cas:authenticationSuccess> </cas:serviceResponse> Yet, I don't know how to access the attribute in client(I am using Spring security 2.0.5). In authenticationProvider, a userDetailsService is configured to read db for authenticated principal. <bean id="casAuthenticationProvider" class="org.springframework.security.providers.cas.CasAuthenticationProvider"> <sec:custom-authentication-provider /> <property name="userDetailsService" ref="clerkManager"/> <!-- other stuff goes here --> </bean> Now in my controller, I can easily do this: Clerk currentClerk = (Clerk)SecurityContextHolder.getContext().getAuthentication().getPrincipal(); Ideally, I can fill the attribute to this Clerk object as another property in some way. How to do this? Or what is recommended approach to share attributes across all apps under CAS's centralized nature?

  • How to detect running on WebSphere

    - by Pedro Guedes
    Hi, I'm building a webapp that should run on both Tomcat and WebSphere and I've managed to make almost all the differences into properties with default values that I can override for deployment on the Tomcat server. I need to do yet another override for the authentication provider bean... public void postProcessBeanFactory(ConfigurableListableBeanFactory beanFactory) throws BeansException { if(isWebSphere()){ LOG.warn("Running on WebSphere... not overriding default authentication mechanism."); return; } LOG.info("Running on Tomcat... overriding authentication provider bean ("+AUTHENTICATION_PROVIDER_BEAN+")"); if (beanFactory.containsBean(AUTHENTICATOR_BEAN) && beanFactory.containsBean(POPULATOR_BEAN) && beanFactory.containsBean(USERDETAIL_PROVIDER_BEAN)){ LdapAuthenticator authenticator = (LdapAuthenticator) beanFactory.getBean(AUTHENTICATOR_BEAN); LdapAuthoritiesPopulator populator = (LdapAuthoritiesPopulator) beanFactory.getBean(POPULATOR_BEAN); UserDetailProvider userDetailProvider = (UserDetailProvider) beanFactory.getBean(USERDETAIL_PROVIDER_BEAN); ExtendedLdapAuthenticationProvider override = new ExtendedLdapAuthenticationProvider(authenticator, populator); override.setUserDetailProvider(userDetailProvider); beanFactory.registerSingleton(AUTHENTICATION_PROVIDER_BEAN, override); } else { throw new BeanCreationException("Could not find required beans to assemble overriding object for authentication..."); } } Now my problem is how to implement the isWebSphere() method. I was thinking Class.forName("someWebSphereSpecific"), but is there a better way?

  • Spring Security: Multiple Logins to the same resources: Form Login + Facebook Connect (uid, sessionK

    - by Daxon
    To begin I know about http://blog.kadirpekel.com/2009/11/09/facebook-connect-integration-with-spring-security/ The only problem is that it completely replaces the Form Login with Facebook Connect. I have the native form login in place, I also have Facebook Connect in place, Upon gathering user information I link it to a native account but without a password. At that point I would like to call a link or method to start process of going into the Spring Security Filter Chain. Here is the source code that works, but am trying to modify. It contains all the files I'm taking about. Now from what I understand I need to add a custom FacebookAuthenticationProvider so that my AuthenticationManager knows about it. <bean id="facebookAuthenticationProvider" class="org.springframework.security.facebook.FacebookAuthenticationProvider"> </bean> <security:authentication-manager alias="authenticationManager"> <security:authentication-provider ref="facebookAuthenticationProvider" /> </security:authentication-manager> Then within the FacebookAuthenticationProvider I would have to call an FacebookAuthenticationToken that would take my the current facebook Uid and SessionKey of the user. Then try authenticate this Token. So where does the FacebookAuthenticationFilter come into it? I'm just trying to understand the order at which these 3 files are called. As if you were trying to implement any other custom authentication. FacebookAuthenticationFilter.java FacebookAuthenticationProvider.java FacebookAuthenticationToken.java I have also posted this on the Spring Security Forum
