  • apache tiles ordering problem

    - by ivar
    I have a problem with the order of rendering tiles. The menu gets rendered first and then the body of our webpage gets rendered. Each tile has it`s own controller that handles everything that tile needs to do. There are two forms. One in the menu and one in the body. Each one changes something in the menu and in the body. The problem is that if a form in the body changes something the menu gets rendered first and then the body controller handles form things and puts data to session, but menu is already done and the session was empty. I cant turn body and menu around becaouse there are other forms that work the other way around. How to deal with this problem? I do want every tile to have its own controller that deals with everything that tile does.

  • One liner for getting a sublist from a Set

    - by yegor256
    Is there a one-liner (maybe from Guava or Apache Collections) that gets a sublist from a set. Internally it should do something like this: public <T> List<T> sublist(Set<T> set, int count) { Iterator<T> iterator = set.iterator(); List<T> sublist = new LinkedList<T>(); int pos = 0; while (iterator.hasNext() && pos++ < count) { sublist.add(iterator.next()); } return sublist; } Obviously, if there are not enough elements it has to return as many as possible.

  • Concurrent Programming:Should I write a sequential program first, then add thread safety?

    - by evthim
    I'm working on a project where we have to create a number of threads(actual number will be inputted in by testers (TA's)). I'm having trouble not only with the programming but also with the design, I can't wrap my head around all of the threads that will be invoked and where I might cause errors. The project is due soon so I don't want to waste time on this if it'll actually set me back, but I was wondering if I should write the program like only one thread will be running and everything should be sequential and then later go back and try to add the thread safety parts of the code? Would that take twice the original amount of time? Project Description: Note:I'm going to be as vague as possible so I don't violate any honor codes, sorry :( your program should accept n number of objectA threads, m number of objectB threads, and r number of objectC objectB threads interact with code in objectA. objectA threads interact with code in objectB and objectC objectB and objectC don't directly interact, but do so indirectly through objectA -ex: objectB needs something from objectA. objectA gets the result for that something by calling objectC my confusion stems mostly from the fact that all of this interactions will be done by m+n threads and there are various restrictions throughout the descriptions, like objectB can request something from objectA, and objectA has to wait for objectC to finish that something before returning it to objectB. Also each objectA thread can only work on one instruction from objectB at a time, etc. etc. I just want to know if I write the code so that there is only 1 objectA, 1 objectB and 1 object C, can I go back and easily modify it so that those 1's can be changed to m, n and r? Sorry again, if my description is a little bit confusing.

  • Representing element as boolean with JAXB?

    - by Marcus
    We have this XML: <Summary> <ValueA>xxx</ValueA> <ValueB/> </Summary> <ValueB/> will never have any attributes or inner elements. It's a boolean type element - it exists (true) or it doesn't (false). JAXB generated a Summary class with a String valueA member, which is good. But for ValueB, JAXB generated a ValueB inner class and a corresponding member: @XmlElement(name = "ValueB") protected Summary.ValueB valueB; But what I'd like is a boolean member and no inner class: @XmlElement(name = "ValueB") protected boolean valueB; How can you do this? I'm not looking to regenerate the classes, I'd like to just make the code change manually. Update: In line with the accepted answer, we created a new method returning the boolean value conditional on whether valueB == null. As we are using Hibernate, we annotated valueB with @Transient and annotated the boolean getter with Hibernate's @Column annotation.

  • GWT: stange import collision error in visualisation api

    - by parag_
    hi, I'm attempting to add two charts to a gwt page using the visualization api, but for some strange and inexplicable reason, eclipse claims that the following two imports are colliding - which makes no sense to me. In the methods where i am calling them, I have even tried using the fully qualified names, but that doesnt seem to help either. Any idea what may be going on ? import com.google.gwt.visualization.client.visualizations.Table.Options; import com.google.gwt.visualization.client.visualizations.LineChart.Options;

  • Hibernate session method to update object

    - by EugeneP
    I need this roadmap of a Hibernate managed object instance. First, I create an instance with initial properties and persist this object in a db. Then session associated with this object is closed. But still, I serialize my object and on the next step deserialize it, invoke some setters, and again, I need to update what changed in a database. What methods of Hibernate session should I use? persist() or save() on the first step and saveOrUpdate() on the second? In fact I see that saveOrUpdate() can be used on each step. What would you recommend?

    For this example from the MongoDB documentation, how do I write the query using MongoTemplate? db.sales.aggregate( [ { $group : { _id : { month: { $month: "$date" }, day: { $dayOfMonth: "$date" }, year: { $year: "$date" } }, totalPrice: { $sum: { $multiply: [ "$price", "$quantity" ] } }, averageQuantity: { $avg: "$quantity" }, count: { $sum: 1 } } } ] ) Or in general, how do I group by a calculated field?

  • Seam @Factory in abstract base class?

    - by Shadowman
    I've got a series of web actions I'm implementing in Seam to perform create, read, update, etc. operations. For my read/update/delete actions, I'd like to have individual action classes that all extend an abstract base class. I'd like to put the @Factory method in the abstract base class to retrieve the item that is to be acted upon. For example, I have this as the base class: public abstract class BaseAction { @In(required=false)@Out(required=false) private MyItem item=null; public MyItem getItem(){...} public void setItem(...){...} @Factory("item") public void initItem(){...} } My subclasses would extend BaseAction, so that I don't have to repeat the logic to load the item that is to be viewed, deleted, updated, etc. However, when I start my application, Seam throws errors saying I have declared multiple @Factory's for the same object. Is there any way around this? Is there any way to provide the @Factory in the base class without encoutnering these errors?

  • How can I retrieve the value of a PASTE (copy-pasta) event in a GWT TextBox?

    - by dominicbri7
    Hello fellow SO members, I want to prevent the user from copy-pasting values in my TextBox IF AND ONLY IF the values do not respect a certain condition. For instance, I created a DigitsOnlyTextBox which will be used for phone numbers. I already made it so only Character.isDigit characters can be typed into the box, and the user cannot copy-paste values into it, using : this.sinkEvents(Event.ONPASTE); and public void onBrowserEvent(Event event) { super.onBrowserEvent(event); // Permet d'empêcher le copier-coller, donc d'entrer des caractères non-numériques if (event.getTypeInt() == Event.ONPASTE) { event.stopPropagation(); event.preventDefault(); } } But I'd like to verify if the copy-pasted String is "digits only" and if so, let the event happen (therefore the text added). tl;dr : see title Thank you for your time. Sincerely.

  • How to inject param in Struts 2 Tag OGNL way

    - by Roy Chan
    Hi Guru, I want to use a property as a param of an object's method. <s:property value="orderProductId" /> returns correct value (e.g. 1) <s:iterator value="%{order.getProductById(1).activations}"> gives me correct value too. But <s:iterator value="%{order.getProductById(#orderProductId).activations}"> doesn't. Not sure why #orderProductId doesn't interpret correctly.

  • Help naming a class that has a single public method called Execute()

    - by devoured elysium
    I have designed the following class that should work kind of like a method (usually the user will just run Execute()): public abstract class ??? { protected bool hasFailed = false; protected bool hasRun = false; public bool HasFailed { get { return hasFailed; } } public bool HasRun { get { return hasRun; } } private void Restart() { hasFailed = false; hasRun = false; } public bool Execute() { ExecuteImplementation(); bool returnValue = hasFailed; Restart(); return returnValue; } protected abstract void ExecuteImplementation(); } My question is: how should I name this class? Runnable? Method(sounds awkward)?

  • How can I display a dialog box for making a choice before a CALL is processed in android?

    - by jsight
    I would like to intercept outgoing calls and pass them to a VOIP application. I see that the Google Voice application has a feature for displaying a question before each call is actually initiated. It provides the user with the choice: Initiate call via Google Voice Initiate call via standard call I would like a way to do something similar with my application (so that not all calls have to be routed through it). At the moment, I can intercept CALL events via a BroadcastReceiver, however, these are not allowed to open dialogs (thus making it possible to display the choice). What is the best way of achieving this goal?

  • Discover NullPointerException bugs using FindBug

    When I run FindBug on this code, it reports NO issues. boolean _closed = false; public void m1(@Nullable String text) { if(_closed) return; System.out.println(text.toLowerCase()); } While here it finds issue as expected: public void m1(@Nullable String text) { System.out.println(text.toLowerCase()); // FireBug: text must be nonnull but is marked as nullable } Why does it fail in first case?
