  • Mergesort : Revision

    - by stan
    Does merge sort work by; taking a list of values splitting it in to two take the first element of each list, the lowest value one goes in to a new list(and i guess removed from the original). comare the next two numbers - do this until one list is empty, then place the rest of the other list at the end ofthe nw list? Also, what are the ramifications of doing this on a linked list? Thanks

  • JPQL (JPA) search substring

    - by JavaBeginner
    Hi, Im facing simple problem with searching entities by some (sub)string, which they might contain. E.g. I have users user1, usr2, useeeer3, user4 and I will enter to search window "use" and I expect to return user1, useeer3, user4. Im sure you know what I mean now. Is there any construction in JPA (JQPL)? It would be nice to search using WHERE somehow in named queries. Something like "SELECT u FROM User u WHERE u.nickname contains :substring"

  • Calling one DAO from another DAO?

    - by es11
    Can this ever make sense? Say I need to fetch an object from the DB which has a relation to another object (represented by a foreign key in the DB, and by a composition in my domain object). If in my first DAO I fetch the data for object 1, then call the dao for object 2, and finally (from within the first DAO, call the setter in object 1 and give it the previously fetched object 2). I know I could do a join instead, but it just seems more logical to me to decouple the functionality (which is why I am skeptical about calling one dao from another). Or should I move some of the logic to the service layer? Thanks Update: I think I solved the problem with help from the answers: all I needed to do was add the following to my mapping of Object 1: <one-to-one name="Object2" fetch="join" class="com...Object2"></one-to-one> I didn't have to change anything else. Thanks for the help!

  • UriBuilder incorrectly encoding Query Parameters value ?

    - by Fred
    Lets consider the following code sample where a path and single parameter are encoded... Parameter name: "param" Parameter value: "foo/bar?aaa=bbb&ccc=ddd" (happens to be a url with query parameters) String test = UriBuilder.fromPath("https://dummy.com"). queryParam("param", "foo/bar?aaa=bbb&ccc=ddd"). build().toURL().toString(); The encoded URL string returned is: "https://dummy.com?param=foo/bar?aaa%3Dbbb&ccc%3Dddd" Is this correct ? Should not the character "&" (and may be even "?") be encoded in the parameter value string ? Would not the URL produced be interpreted as follow: One first parameter, name="param", value = "ar?aaa%3Dbbb" followed by a second parameter, name="ccc%3Dddd", without value.

  • Javas Math.sin() produces NaN all the time

    - by milan1612
    Forgive me if this is a dumb beginners problem, but I really don't get it. I have a member variable declared like so: public Double Value; When I assign 3.14159265 to Value and try to compute the sine of it, this happens: system.out.println(Value.toString()); //outputs 3.14159265 Value = Math.sin(Value); system.out.println(Value.toString()); //outputs NaN In fact, this happens with every single value I tried - even with 0! Math.sin() seems to always produce NaN as a result, regardless of the arguments value. The docs say: If the argument is NaN or an infinity, then the result is NaN. But my argument is clearly not NaN or infinity! What the heck is happening there?

  • alternatedocroot

    - by ring bearer
    Using Sun Glassfish Enterprise server v2.1.1 I am using "alternatedocroot" via sun-web.xml for my web application to abstract out static content from actual deploy-able code (EAR/WAR) What I have is a cluster of two server instances distributed across two physical hosts - HOST1 and HOST2. "alternatedocroot" points to /data/static-content/ on both HOST1 and HOST2. Would DAS (Domain application server )take care of syncing /data/static-content between HOST1 and HOST2 if I use syncinstances=true option while starting up the cluster? Thanks!

  • Use case of Glass Pane vs. Layered Pane

    - by Amanda S
    I've always been a little fuzzy on the difference between the glass pane and a layered pane. Is the glass pane essentially just "the very top layer of the root pane," or does it behave differently? When would you use a layered pane instead of the glass pane?

  • Axis2 Class Generation

    - by Jack
    I have an instance of a derived class (called Child) that I would like to send between the client and server of my web service. However, the method that might be returning this instance, is marked as returning an instance of the parent class (called Parent). For example: public class Service{public Parent createInstanceOfParentOrChildObject();} While Child is not a parameter anywhere in the service nor is it ever specifically named as a return type (only Parent is ever named), it is nonetheless generated and returned inside certain methods (and then cast to Parent). I generated the wsdl file using Axis2 1.4.1 java2wsdl and specifying that it include this class (using the -xc parameter). I did not use Axis2 1.5.1 because it was not honoring the -xc parameter though it looks like that bug is supposedly fixed in Axis2 1.6. I even did a quick check of the generated .wsdl file to ensure that it did indeed include a definition for Child (and, of course, Parent). However, when I used wsdl2java to generate the server-side (and client-side) code, Child was not generated. How can I get wsdl2java to generate Child? I realize that I could do this by hand but I don't want to have to do this for both the client and server. I was also hoping that I could make this as easy as possible for people to use my wsdl to generate their own clients.

  • JAXB - Beans to XSD or XSD to beans?

    - by bajafresh4life
    I have an existing data model. I would like to express this data model in terms of XML. It looks like I have two options if I'm to use JAXB: Create an XSD that mirrors my data model, and use xjc to create binding objects. Marshalling and unmarshalling will involve creating a "mapping" class that would take my existing data objects and map them to the objects that xjc created. For example, in my data model I have a Doc class, and JAXB would create another Doc class with basically the same exact fields, and I would have to map from my Doc class to xjc's Doc class. Annotate my existing data model with JAXB annotations, and use schemagen to generate an XSD from my annotated classes. I can see advantanges and disadvantages of both approaches. It seems that most people using JAXB start with the XSD file. It makes sense that the XSD should be the gold standard truth, since it expresses the data model in a truly cross-platform way. I'm inclined to start with the XSD first, but it seems icky that I have to write and maintain a separate mapping class that shuttles data in between my world and JAXB world. Any recommendations?

  • JBoss ignores @RemoteBinding annotation

    - by tputkonen
    I would like to specify JNDI name for an EJB3 bean using annotation, but JBoss 5.1.0 GA seems to ignore the annotation completely. Bean's annotations are: @Remote(Foobar.class) @Stateless(name = "Foobar") @TransactionManagement(TransactionManagementType.BEAN) @RemoteBinding(jndiBinding="ejb/Foobar") public class FoobarBean implements Foobar { ... I tested deploying also using @RemoteBindings annotation, but the result was same: @RemoteBindings({@RemoteBinding(jndiBinding="ejb/Foobar")}) The bean does not get bound to JNDI with the specified name, and the log file doesn't give any clues.

  • JTable row filters updates

    - by Jeff Storey
    Is there a way to tell a JTable's row filter that it should update itself to display the filtered data? I'm currently using the fireTableDataChanged method in the AbstractTableModel but the underlying data for the table isn't actually changing, so this seems like it might be wasteful. The way my filter works is to check if data in the table is in some other list and only display it if it is in that list. So that other list changed and I need to tell the filter to refresh itself. Is fireTableDataChanged the correct way to do this? thanks, Jeff

  • How to get image's coordinate on JPanel

    - by Jessy
    This question is related to my previous question http://stackoverflow.com/questions/2376027/how-to-generate-cartesian-coordinate-x-y-from-gridbaglayout I have successfully get the coordinate of each pictures, however when I checked the coordinate through (System.out.println) and the placement of the images on the screen, it seems to be wrong. e.g. if on the screen it was obvious that the x point of the first picture is on cell 2 which is on coordinate of 20, but the program shows x=1. Here is part of the code: public Grid (){ setPreferredSize(new Dimension(600,600)); .... setLayout(new GridBagLayout()); GridBagConstraints gc = new GridBagConstraints(); gc.weightx = 1d; gc.weighty = 1d; gc.insets = new Insets(0, 0, 0, 0);//top, left, bottom, and right gc.fill = GridBagConstraints.BOTH; JLabel[][] label = new JLabel[ROWS][COLS]; Random rand = new Random(); // fill the panel with labels for (int i=0;i<IMAGES;i++){ ImageIcon icon = createImageIcon("myPics.jpg"); int r, c; do{ //pick random cell which is empty r = (int)Math.floor(Math.random() * ROWS); c = (int)Math.floor(Math.random() * COLS); } while (label[r][c]!=null); //randomly scale the images int x = rand.nextInt(50)+30; int y = rand.nextInt(50)+30; Image image = icon.getImage().getScaledInstance(x,y, Image.SCALE_SMOOTH); icon.setImage(image); JLabel lbl = new JLabel(icon); // Instantiate GUI components gc.gridx = r; gc.gridy = c; add(lbl, gc); //add(component, constraintObj); label[r][c] = lbl; } I checked the coordinate through this code: Component[] components = getComponents(); for (Component component : components) { System.out.println(component.getBounds()); }

  • prevent bots to query my database several times

    - by Alain
    Hi all, I'm building an application that is a kind of registry. Think about the dictionary: you lookup for a word and it return something if the word is founded. Now, that registry is going to store valuable informations about companies, and some could be tempted to get the complete listing. My application use EJB 3.0 that replies to WS. So I was thinking about permits a maximum of 10 query per IP address per day. Storing the IP address and a counter on a table that would be empty by a script every night. Is it a good idea/practice to do so? If yes, how can I get the IP address on the EJB side? Is there a better way to prevent something to get all the data from my database? I've also though about CAPTCHA but I think it's a pain for the user, and sometime, they are difficult to read even for real human. Hope it's all clear since I'm not english... Thanks Alain

  • Dependency on Spring's annotations

    - by Jacques René Mesrine
    I have annotated my classes with @Repository, @Resource, @Component, @Service annotations but these classes must run in 2 environments. The first environment is Spring 2.x based while the other has no spring at all. I'm sure the code will fail without the spring jars & I want to know ideas from you on how I can retain the annotations but still work in both environments

That been said am having some trouble implementing a the server side for RTPSockets. After looking at their illustrations and example. I am still abit confused. Am I to develop a datasource and also datasink classes to handle the transfer? What am trying to do is stream data from my application to the underlying network and receive it back through another application. I have and understand receiving but just can't get my head around the steps involved for sending. Any help would be most appreciated.

  • How do I determine that an instance of org.apache.poi.hwpf.model.ListData belongs to a numbered lis

    - by leighgordy
    Is there a way to determine if an instance of a org.apache.poi.hwpf.model.ListData belongs to a numbered list or bulleted list? I am using Apache Poi's org.apache.poi.hwpf.HWPFDocument class to read the contents of a word document in order to generate HTML. I can identify the list items in the document by checking to see that the paragraph I am working with is an instance of org.apache.poi.hwpf.model.ListData. I can not find a way to determine if ListData belongs to a bulleted list or a numbered list.

  • Repackaging Jasper-Reports into an application specific OSGi bundle, legal or not?

    - by Chris
    Hi, I wanted to ask (probably a silly) question regarding the packaging of existing open-source components as OSGi bundles (more specifically Jasper Reports). I have an application that I am converting from a monolithic jar-hell type architecture to something more moduler and OSGi is my weapon of choice. There are various modules I have in mind but one of the modules is a reporting module. My own reporting module will be a jar file containing my code that should reference a Jasper Reports bundle. Trouble is, Jasper reports depends on far far too many libraries and is quite monolithic in its own right. I therefore wish to build my own Jasper Reports bundle but this is where I start getting confused about the legality of repackaging. I don't plan to re-compile but I do plan to re-bundle removing known items that I do not require. Can anyone offer advice on whether I am permitted to repackage (not recompile or extend) open-source libraries into OSGi bundles without falling foul of 'derivative works' clause of LGPL? I noticed that Groovy seems to offer some monolithic jars that include all dependancies and actually goes so far as to re-arrange the packages of its dependancies so that there are no namespace conflicts. This seems to me to be a violation of the license but if anyone can reassure me that this is legal then I would feel safer about my less intrusive custom-bundling of Jasper reports. Thanks for your time, Chris

  • SIP servlets, chatserver

    - by Senne
    I'm trying to get a SIP servlet chat server working, together with the textclient found here. When I use 2 clients to send messages to eachother (peer to peer), everything goes well. But when I use one or more clients together with my server, I have to wait exactly 32 seconds before the server picks up any new messages in the doMessage() method. I'm using Netbeans together with Sailfin as my SIP server. Is there some kind of limitation or configurable delay or timeout between requests or responses in Sailfin I'm looking over? I can post the server code, if needed. Thanks

  • WTK emulator bluetooth connection problem

    - by Gokhan B.
    Hi! I'm developing a J2ME program with eclipse / WTK 2.5.2 and having problem with connecting two emulators using bluetooth. There is one server and one .client running on two different emulators. The problem is client program cannot discover any bluetooth device. Here is the server and client codes: public Server() { try { LocalDevice local = LocalDevice.getLocalDevice(); local.setDiscoverable(DiscoveryAgent.GIAC); server = (StreamConnectionNotifier) Connector.open("btspp://localhost:" + UUID_STRING + ";name=" + SERVICE_NAME); Util.Log("EchoServer() Server connector open!"); } catch (Exception e) {} } after calling Connector.open, I get following warning in console, which i believe is related: Warning: Unregistered device: unspecified and client code that searches for devices: public SearchForDevices(String uuid, String nm) { UUIDStr = uuid; srchServiceName = nm; try { LocalDevice local = LocalDevice.getLocalDevice(); agent = local.getDiscoveryAgent(); deviceList = new Vector(); agent.startInquiry(DiscoveryAgent.GIAC, this); // non-blocking } catch (Exception e) {} } system never calls deviceDiscovered, but calls inquiryCompleted() with INQUIRY_COMPLETED paramter, so I suppose client program runs fine. Bluetooth is enabled at emulator settings.. any ideas ?

  • How do I add a namespace attribute to an element in JAXB when marshalling?

    - by Ryan Elkins
    I'm working with eBay's LMS (Large Merchant Services) and kept running into the error: org.xml.sax.SAXException: SimpleDeserializer encountered a child element, which is NOT expected, in something it was trying to deserialize. After alot of trial and error I traced the problem down. It turns out this works: <?xml version="1.0" encoding="UTF-8"?> <BulkDataExchangeRequests xmlns="urn:ebay:apis:eBLBaseComponents"> <Header> <Version>583</Version> <SiteID>0</SiteID> </Header> <AddFixedPriceItemRequest xmlns="urn:ebay:apis:eBLBaseComponents"> while this (what I've been sending) doesn't: <?xml version="1.0" encoding="UTF-8"?> <BulkDataExchangeRequests xmlns="urn:ebay:apis:eBLBaseComponents"> <Header> <Version>583</Version> <SiteID>0</SiteID> </Header> <AddFixedPriceItemRequest> The difference is the xml namespace attribute on the AddFixedPriceItemRequest . All of my XML is currently being marshalled via JAXB and I'm not sure what is the best way to go about adding a second xmlns attribute to a different element in my file. So that's the question. How do I add an xmlns attribute to another element in JAXB? UPDATE: package ebay.apis.eblbasecomponents; import javax.xml.bind.annotation.XmlAccessType; import javax.xml.bind.annotation.XmlAccessorType; import javax.xml.bind.annotation.XmlElement; import javax.xml.bind.annotation.XmlType; @XmlAccessorType(XmlAccessType.FIELD) @XmlType(name = "AddFixedPriceItemRequestType", propOrder = { "item" }) public class AddFixedPriceItemRequestType extends AbstractRequestType { @XmlElement(name = "Item") protected ItemType item; public ItemType getItem() { return item; } public void setItem(ItemType value) { this.item = value; } } Added class definition by request. UPDATE 2: Edited the above class like so to no effect: @XmlAccessorType(XmlAccessType.FIELD) @XmlType(namespace = "urn:ebay:apis:eBLBaseComponents", name = "AddFixedPriceItemRequestType", propOrder = { "item" }) public class AddFixedPriceItemRequestType UPDATE 3: Here is a snippet of the BulkDataExchangeRequestsType class. I tried throwing a namespace="urn:ebay:apis:eBLBaseComponents" into the @XmlElement for AddFixedPriceItemRequest but it didn't do anything. @XmlAccessorType(XmlAccessType.FIELD) @XmlType(name = "BulkDataExchangeRequestsType", propOrder = { "header", "addFixedPriceItemRequest" }) public class BulkDataExchangeRequestsType { @XmlElement(name = "Header") protected MerchantDataRequestHeaderType header; @XmlElement(name = "AddFixedPriceItemRequest") protected List<AddFixedPriceItemRequestType> addFixedPriceItemRequest; UPDATE 4: Here's the hideous chunk of code that is updating the xml after marshalling for me. This is currently working although I'm not particulary proud of it. DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance(); dbf.setNamespaceAware(true); DocumentBuilder db = dbf.newDocumentBuilder(); Document doc = db.newDocument(); marshaller.marshal(request, doc); NodeList nodes = doc.getChildNodes(); nodes = nodes.item(0).getChildNodes(); for(int i = 0; i < nodes.getLength(); i++){ Node node = nodes.item(i); if (!node.getNodeName().equals("Header")){ ((Element)node).setAttribute("xmlns", "urn:ebay:apis:eBLBaseComponents"); } } Update 5: For anyone else that runs into this problem with eBay and wonders why - The reasoning behind this most likely has to do with how eBay is handling these requests. The BulkDataExchange probably takes the XML payload, breaks it up, and send the pieces out to the Merchant or Trading API. The inner pieces of the payload then do not have the namespace and the get the error. This is a guess on my part but I wouldn't be surprised if this is what was going on behind the scenes. Thanks for all the help everyone.
