  • Losing sessions on GlassFish

    - by synti
    I have a web application that logs users in a @SessionScoped managed bean. It's all the basic stuff, pretty much like this: users logs in using regular http form and gets redirect to user area (wich is protected using a filter). But if any resource on that area is accessed, the request somehow uses a new session, wich has no managed bean, no user, and the filter does his job, redirecting him to login page. Here's the login form: <h:form> <h:outputLabel for="email" value="Email "/> <p:inputText id="email" size="30" value="#{loginManager.email}"/> <h:outputLabel for="password" value="Password "/> <p:password id="password" size="12" value="#{loginManager.password}"/> <p:commandButton value="Login" action="#{loginManager.login()}"/> </h:form> The loginManager managed bean: @ManagedBean @SessionScoped public class LoginManager implements Serializable { @EJB private UserService userService; private User user; private String email; private String password; public String login() { user = userService.findBy(email, password); if (user == null) { // FacesMessage stuff } else { return "/user/welcome.xhtml?faces-redirect=true"; } } public String logout() { FacesContext.getCurrentInstance().getExternalContext().invalidateSession(); return "/index.xhtml?faces-redirect=true"; } // Getters, setters (no setter for user) and serialVersionUID And then comes the filter that protects the user area: @WebFilter(urlPatterns="/user/*", displayName="UserFilter") public class UserFilter implements Filter { @Override public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException { HttpSession session = ((HttpServletRequest)request).getSession(false); LoginManager loginManager = (LoginManager) session.getAttribute("loginManager"); if (loginManager == null || !loginManager.hasUser()) { HttpServletResponse resp = (HttpServletResponse) response; resp.sendRedirect("index.xhtml"); } final User user = loginManager.getUser(); if (user.isValid()) { chain.doFilter(request, response); } else { HttpServletResponse resp = (HttpServletResponse) response; resp.sendRedirect("index.xhtml"); } } The UserService is just a stateless EJB that handles persistence. Part of the JSF for user area: <h:form> <p:panelMenu> <p:submenu label="Items"> <p:menuitem value="Add item" action="#{userItens.addItems}" ajax="false"/> <p:menuitem value="My items" /> </p:submenu> </p:panelMenu> </h:form> And finally the userItens managed bean. @ManagedBean @RequestScoped public class UserItens { private User user; @PostConstruct private void init() { HttpSession session = (HttpSession) FacesContext.getCurrentInstance() .getExternalContext().getSession(false); LoginManager loginManager = (LoginManager) session.getAttribute("loginManager"); if (loginManager != null) user = loginManager.getUser(); } public String addItems() { // Doesn't get here. Seems like UserFilter comes first, doesn't find // an user and redirects. } I'm using glassfish and session timeout is now on 0.

  • synchronized block in JSP tag class

    - by Sudhakar
    Hi, I am trying to find answer for the following ,for the past couple of days ,but couldnt find comprehensive answer Problem Statement I have a custom JSP tag class which handles a web form submission ,captures data and write it to same file in the filesystem. As all web applications,this can be triggeredsimultaneosly ,and i fear that multiple threads would be in action handling each of the submission (we all know thats how Servlet works.) CODE synchronized (this){ final String reportFileName = "testReport.csv"; File reportDir = new File( rootCsDirectory, "reports" ); if(!reportDir.isDirectory())reportDir.mkdir(); File reportFile = new File (reportDir, reportFileName); logReport(reportFile,reportContent.toString()); } ISSUE: - A File object can be opened by one thread for writing and at same time another thread might try to access and fail and throw an exception So i thought of synchronizing (on the object ) should solve the issue , but read some where that jsp engine would have pool of jsp tag objects, so i am afraid that synchronized (this) wont work and it should be changed to synchronized (this.getClass())

  • Why encodeXxx methods in UIComponent accept FacesContext parameter?

    - by Roman
    I haven't ever before created custom component in jsf so I've noticed it only now that methods like encodeBegin(), encodeEnd() etc accept FacesContext parameter. FacesContext instance can usually be received with FacesContext.getCurrentInstance(). So, I wonder whether these methods have FacesContext parameter just for convenience or some different objects can be passed there (maybe from external resources..). If the latter is possible then could you give an example pls.

  • eclipse add unimplemented methods including javadoc

    - by dcp
    When implementing an interface in eclipse, it has a really nice feature that lets you "add unimplemented methods", and it will generate the method stubs for the interface methods. However, it does not bring along the method documentation from the interface methods, and I was wondering if there was a way to get eclipse to do that.

  • jsFunction pass data to backingbean

    - by deilig
    I have a javascript that is calling a function addData(param1,param2,param3,param4) which is calling addClip at the end And I need to pass those to a backing bean. <a4j:form> <a4j:jsFunction name="addClip" action="#{backingBean.goGo}"> <a4j:actionparam name="param1" assignTo="#{backingBean.param1}"/> </a4j:jsFunction> </a4j:form> But I can't seem to pass any values to the backingbean. I've even tried setting a static value for the actionparam. But when I try to do a Systemout on the setParam1 method it only prints out null. Have I missed anything important?

  • What happens to my PriorityQueue if my Comparator throws an exception while it's busy bubbling up or

    - by nieldw
    Hi, I'm trying order pairs of integers ascendantly where a pair is considered less than another pair if both its entries are strictly less than those of the other pair, and larger than the other pair if both its entries are strictly larger than those of the other pair. All other cases are considered incomparable. They way I want to solve this is by defining a Comparator that implements the above, but will throw an exception for incomparable cases, and provide that to a PriorityQueue. Of course, while inserting a pair the priority queue does several comparisons while bubbling the new entry up to its correct position in the heap, and many of these will be comparable. But it may happen during the bubbling process that a pair is encountered with which this new pair is incomparable, and an exception will be thrown. If this happens, what will be the state of the PriorityQueue? Will the pair I was trying to insert sit in the heap at the last position it was in before the exception was thrown? If I use the PriorityQueue's remove(Object o) method, will the PriorityQueue be restored to a consistent state? Thanks

  • JSP request parameter is returning null on a jsp include with Weblogic.

    - by doug
    Hello, I am having trouble with the jsp:include tag. I have code like the following: <jsp:include page="./Address.jsp"> <jsp:param value="30" name="tabIndex"/> <jsp:param value="true" name="showBox"/> <jsp:param value="none" name="display"/> </jsp:include> The page is included fine, but when I try to access the parameters on the Address.jsp page, they are null. I have tried accessing them the following ways (with jstl): <c:out value="${param.tabIndex}" /> <c:out value="${param['tabIndex']} /> <%= request.getParameter("tabIndex") %> <c:out value="${pageScope.param.tabIndex} /> ${param.tabIndex} etc... Here is the kicker, The above works fine in tomcat 5.5. However, when I deploy the application in Weblogic 10, it does not. Also, the code works fine in other areas of my application (on weblogic) just not a particular page. Any Ideas? Thanks!

  • Android - Making an activity display different things depending on what is clicked

    - by user3682017
    I have a listview that is populated by an arraylist of classes. public void populateThingsList(){ listExample.add(new Example("Example name", 1, "Example detail 1", "Example detail 2", R.drawable.1_icon, "Example detail 3")); listExample.add(new Example("Example name1", 2, "Example detail 1", "Example detail 2", R.drawable.2_icon, "Example detail 3")); listExample.add(new Example("Example name2", 3, "Example detail 1", "Example detail 2", R.drawable.3_icon, "Example detail 3")); listExample.add(new Example("Example name3", 4, "Example detail 1", "Example detail 2", R.drawable.4_icon, "Example detail 3")); listExample.add(new Example("Example name4", 5, "Example detail 1", "Example detail 2", R.drawable.5_icon, "Example detail 3")); listExample.add(new Example("Example name5", 6, "Example detail 1", "Example detail 2", R.drawable.6_icon, "Example detail 3")); listExample.add(new Example("Example name6", 7, "Example detail 1", "Example detail 2", R.drawable.7_icon, "Example detail 3")); listExample.add(new Example("Example name7", 8, "Example detail 1", "Example detail 2", R.drawable.8_icon, "Example detail 3")); listExample.add(new Example("Example name8", 9, "Example detail 1", "Example detail 2", R.drawable.9_icon, "Example detail 3")); listExample.add(new Example("Example name9", 10, "Example detail 1", "Example detail 2", R.drawable.10_icon, "Example detail 3")); } This is the code for the clicklistener. ListView list = (ListView) findViewById(R.id.exampleListView); list.setOnItemClickListener(new AdapterView.OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { Example clickedexample = listExample.get(position); startActivity(new Intent("com.example.app.EXAMPLEACTIVITY")); } } Is there any way I can get the information from clickedExample and set the textViews and imageView in ExampleActivity depending on which one was clicked?

  • PulpCore OGG music playback - can't loop as soon as I animate the musicVolume property

    - by Peter Perhác
    I have been experimenting with PulpCore for about a week or so and I am enjoying it very much but today I ran into a problem that I can't quite figure out. Sound bgMusic = Sound.load("music/music.ogg"); Playback musicPlayback; ... musicVolume = new Fixed(0.75); musicPlayback = bgMusic.loop(musicVolume); //TODO figure out why it's NOT looping when volume is animated // musicVolume.animate(0, musicVolume.get(), FADE_IN_TIME); This code, for as long as the last line is commented out, plays the music.ogg again and again in an endless loop (which I can stop by calling stop on the Playback object returned from loop(). However, I would like the music to fade in smoothly, so following the advice of the PulpCore API docs, I added the last line which will create the fade-in but the music will only play once and then stop. I wonder why is that? Here is a bit of the documentation: Playback pulpcore.sound.Sound.loop(Fixed level) Loops this sound clip with the specified volume level (0.0 to 1.0). The level may have a property animation attached. Parameters: level Returns: a Playback object for this unique sound playback (one Sound can have many simultaneous Playback objects) or null if the sound could not be played. So what could be the problem? I repeat, with the last line, the sound fades in but doesn't loop, without it it loops but starts with the specified 0.75 volume level.

  • Android Broadcast Address

    - by Eef
    Hey, I am making a Client Server application for my Android phone. I have created a UDP Server in Python which sits and listens for connections. I can put either the server IP address in directly like 192.169.0.100 and it sends data fine. I can also put in 192.168.0.255 and it find the server on 192.169.0.100. Is it possible to get the broadcast address of the network my Android phone is connected to? I am only ever going to use this application on my Wifi network or other Wifi networks. Cheers

  • Defining a dd/mm/yyyy field within an abstract table model

    - by Simon Andi
    I have defined an abstract table model but one of the columns should house date values as dd/mm/yyyy format not sure how to do this. I have a external global file and have hard coded the dates as dd/mm/yyyy. How can I define this column within my abstract table model so that to only allow only dates having dd/mm/yyyy format. public class OptraderGlobalParameters { public static boolean DEBUG = true; //Set DEBUG = true for Debugging /*=========================*/ /*Table Array For Dividends*/ /*=========================*/ public static String[] columnNames = {"Date", "Dividend", "Actual", "Yield (%)" }; public static Object[][] data = { {"dd/mm/yyyy", new Double(5), new Boolean(false), new Boolean(false)}, {"dd/mm/yyyy", new Double(5), new Boolean(false), new Boolean(false)}, {"dd/mm/yyyy", new Double(5), new Boolean(false), new Boolean(false)}, {"dd/mm/yyyy", new Double(5), new Boolean(false), new Boolean(false)}, {"dd/mm/yyyy", new Double(5), new Boolean(false), new Boolean(false)}, }; }

  • JSF: how to update the list after delete an item of that list

    - by Harry Pham
    It will take a moment for me to explain this, so please stay with me. I have table COMMENT that has OneToMany relationship with itself. @Entity public class Comment(){ ... @ManyToOne(optional=true, fetch=FetchType.LAZY) @JoinColumn(name="REPLYTO_ID") private Comment replyTo; @OneToMany(mappedBy="replyTo", cascade=CascadeType.ALL) private List<Comment> replies = new ArrayList<Comment>(); public void addReply(NewsFeed reply){ replies.add(reply); reply.setReplyTo(this); } public void removeReply(NewsFeed reply){ replies.remove(reply); } } So you can think like this. Each comment can have a List of replies which are also type Comment. Now it is very easy for me to delete the original comment and get the updated list back. All I need to do after delete is this. allComments = myEJB.getAllComments(); //This will query the db and return updated list But I am having problem when trying to delete replies and getting the updated list back. So here is how I delete the replies. Inside my managed bean I have //Before invoke this method, I have the value of originalFeed, and deletedFeed set. //These original comments are display inside a p:dataTable X, and the replies are //displayed inside p:dataTable Y which is inside X. So when I click the delete button //I know which comment I want to delete, and if it is the replies, I will know //which one is its original post public void deleteFeed(){ if(this.deletedFeed != null){ scholarEJB.deleteFeeds(this.deletedFeed); if(this.originalFeed != null){ //Since the originalFeed is not null, this is the `replies` //that I want to delete scholarEJB.removeReply(this.originalFeed, this.deletedFeed); } feeds = scholarEJB.findAllFeed(); } } Then inside my EJB scholarEJB, I have public void removeReply(NewsFeed comment, NewsFeed reply){ comment = em.merge(comment); comment.removeReply(reply); em.persist(comment); } public void deleteFeeds(NewsFeed e){ e = em.find(NewsFeed.class, e.getId()); em.remove(e); } When I get out, the entity (the reply) get correctly removed from the database, but inside the feeds List, reference of that reply still there. It only until I log out and log back in that the reply disappear. Please help

  • Setting a value into a object using reflection

    - by marionmaiden
    Hello I have an object that has a lot of attributes, each one with it's getter and setter. Each attribute has a non primitive type, that I don't know at runtime. For example, what I have is this: public class a{ private typeA attr1; private typeB attr2; public typeA getAttr1(){ return attr1; } public typeB getAttr2(){ return attr2; } public void setAttr1(typeA at){ attr1 = at; } public void setAttr2(typeB at){ attr2 = at; } } public class typeA{ public typeA(){ // doesn't matter } } public class typeB{ public typeB(){ // doesn't matter } } So, using reflection, I obtained the setter method for an attribute. Setting a value in the standard way is something like this: a test = new a(); a.setAttr1(new typeA()); But how can I do this using reflection? I already got the setAttr1() method using reflection, but I don't know how to create a new typeA object to be inserted in the setter.

  • how to programmatically register an already setup bean to spring context

    - by lisak
    Hey, I'm wondering how one can do that. Afaik there is BeanFactoryPostProcessor interface that let us use BeanDefinitionRegistry.registerBeanDefinition() method before beans within context are initialized. That method accepts only a class / definition. But usually one needs to register a bean that is already set with properties. Otherwise the bean definition registration itself is kinda useless. I don't want to set it up additionally after I get it from context then. When using singleton it's ok, but for prototypes I'd have to set the bean up for each getBean() .
