  • Best way to get free driving instructions

    - by Chris
    Is there a simple way to get driving instructions? Something like: I call "http://someservice/?start=NYC&target=Washington" and then the service returns a XML file containing routing information? Has anybody ever tried to access such a web-based service from a standalone desktop application? Any help would really be appreciated! Update: Thanks for the hints, but unfortunately I can't run JavaScript. Is there still a possibility to receive driving instructions?

  • JAXB adding namespace to parent but not to the child elements contained

    - by Nishant
    I put together an XSD and used JAXB to generate classes out of it. Here are my XSDs- myDoc.xsd : <?xml version="1.0" encoding="UTF-8"?> <xs:schema xmlns="http://www.mydoc.org" targetNamespace="http://www.mydoc.org" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:mtp="http://www.mytypes.com" elementFormDefault="qualified"> <xs:import namespace="http://www.mytypes.com" schemaLocation="mytypes.xsd" /> <xs:element name="myDoc"> <xs:complexType> <xs:sequence> <xs:element name="crap" type="xs:string"/> <xs:element ref="mtp:foo"/> <xs:element ref="mtp:bar"/> </xs:sequence> </xs:complexType> </xs:element> mytypes.xsd <?xml version="1.0" encoding="UTF-8"?> <xs:schema targetNamespace="http://www.mytypes.com" xmlns="http://www.mytypes.com" xmlns:tns="http://www.mytypes.com" xmlns:xs="http://www.w3.org/2001/XMLSchema" attributeFormDefault="qualified" elementFormDefault="qualified"> <xs:element name="foo" type="tns:Foo"/> <xs:element name="bar" type="tns:Bar"/> <xs:element name="spam" type="tns:Spam"/> <xs:simpleType name="Foo"> <xs:restriction base="xs:string"></xs:restriction> </xs:simpleType> <xs:complexType name="Bar"> <xs:sequence> <xs:element ref="spam"/> </xs:sequence> </xs:complexType> <xs:simpleType name="Spam"> <xs:restriction base="xs:string" /> </xs:simpleType> </xs:schema> The document marshalled is- <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <myDoc xmlns:ns2="http://www.mytypes.com"> <crap>real crap</crap> <ns2:foo>bleh</ns2:foo> <ns2:bar> <spam>blah</spam> </ns2:bar> </myDoc> Note that the <spam> element uses the default namespace. I would like it to use the ns2 namespace. The schema (mytypes.xsd) expresses the fact that <spam> is contained within <bar> which in the XML instance is bound to the ns2 namespace. I've broken my head over this for over a week and I would like ns2 prefix to appear in <spam>. What should I do? Required : <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <myDoc xmlns:ns2="http://www.mytypes.com"> <crap>real crap</crap> <ns2:foo>bleh</ns2:foo> <ns2:bar> <ns2:spam>blah</ns2:spam><!--NS NS NS--> </ns2:bar> </myDoc>

  • Is context:annotation-config an alternative to @AutoWired?

    - by Antacid
    Is it correct that I can put context:annotation-config in my XML config and it will automatically inject the bean class without needing any annotations? So instead of using these annotation types: public class Mailman { private String name; @Autowired private Parcel Parcel; public Mailman(String name) { this.name = name; } @Autowired public void setParcel(Parcel Parcel) { this.Parcel = Parcel; } @Autowired public void directionsToParcel(Parcel Parcel) { this.Parcel = Parcel; } } I would just need to write this: <beans ... > <bean id="mailMan" class="MailMan"> <constructor-arg value="John Doe"/> </bean> <bean id="parcel" class="Parcel" /> <context:annotation-config /> </beans> and then my MailMan class would look a lot simpler without the need for annotations: public class Mailman { private String name; private Parcel Parcel; public Mailman(String name) { this.name = name; } }

  • Weak hashmap with weak references to the values?

    - by Razor Storm
    I am building an android app where each entity has a bitmap that represents its sprite. However, each entity can be be duplicated (there might be 3 copies of entity asdf for example). One approach is to load all the sprites upfront, and then put the correct sprite in the constructors of the entities. However, I want to decode the bitmaps lazily, so that the constructors of the entities will decode the bitmaps. The only problem with this is that duplicated entities will load the same bitmap twice, using 2x the memory (Or n times if the entity is created n times). To fix this, I built a SingularBitmapFactory that will store a decoded Bitmap into a hash, and if the same bitmap is asked for again, will simply return the previously hashed one instead of building a new one. Problem with this, though, is that the factory holds a copy of all bitmaps, and so won't ever get garbage collected. What's the best way to switch the hashmap to one with weakly referenced values? In otherwords, I want a structure where the values won't be GC'd if any other object holds a reference to it, but as long as no other objects refers it, then it can be GC'd.

  • How to find longest common substring using trees?

    - by user384706
    The longest common substring problem according to wiki can be solved using a suffix tree. From wiki: The longest common substrings of a set of strings can be found by building a generalised suffix tree for the strings, and then finding the deepest internal nodes which have leaf nodes from all the strings in the subtree below it I don't get this. Example: if I have: ABCDE and XABCZ then the suffix tree is (some branches from XABCZ omitted due to space): The longest common substring is ABC but it is not I can not see how the description of wiki helps here. ABC is not the deepest internal nodes with leaf nodes. Any help to understand how this works?

  • SELECT * FROM <table> BETWEEN <value typed in a JTextField> AND <idem>

    - by Rodrigo Sieja Bertin
    In this part of the program, the JInternalFrame file FrmMovimento, I made a button called Visualizar ("View"). Based on what we type on the text fields, it must show the interval the user defined. There are these JTextFields: Code from: _ To: _ Asset: _ And these JFormattedTextFields: Date from: _ To: _ There are registers appearing already in the JDesktopPane from JInternalFrame FrmListarMov, if I use another SELECT statement selecting all registers, for example. But not if I type as I did in the title: public List<MovimentoVO> Lista() throws ErroException, InformacaoException{ List<MovimentoVO> listaMovimento = new ArrayList<> (); try { MySQLDAO.getInstancia().setAutoCommit(false); try (PreparedStatement stmt = MySQLDAO.getInstancia().prepareStatement( "SELECT * FROM Cadastro2 WHERE Codigo BETWEEN "+ txtCodDeMov +" AND "+ txtCodAteMov +";") { ResultSet registro = stmt.executeQuery(); while(registro.next()){ MovimentoVO Movimento = new MovimentoVO(); Movimento.setCodDeMov(registro.getInt(1)); Movimento.setCodAteMov(registro.getInt(2)); Movimento.setAtivoMov(registro.getString(3)); Movimento.setDataDeMov(registro.getString(4)); Movimento.setDataAteMov(registro.getString(5)); listaMovimento.add(Movimento); } } } catch (SQLException ex) { throw new ErroException(ex.getMessage()); } catch (InformacaoException ex) { throw ex; } return listaMovimento; } In the SELECT line, txtCodDeMov is how I named the JTextField of "Code from" and txtCodAtemov is how I named the JTextField of the first "To". Oh, I'm using NetBeans 7.1.2 (Build 201204101705) and MySQL Ver 14.14 Distrib 5.1.63 in a Linux Mint 12 64-bits.

  • Connecting to an RMI object without registry

    - by Mark Probst
    I think I need to connect to a remote RMI object without going through the registry, but I don't know how. My situation is this: I'm implementing a simple job distribution service which consists of one distributor and multiple workers. The distributor has a registered RMI object to which clients connect to send jobs, and workers connect to accept jobs. Unfortunately the distributor and worker hosts are behind a firewall. To get to the distributor host I am tunneling two ports (one for the registry, one for the distributor object) via SSH, so I can get to the registry and the distributor from outside the firewall. To make that work I have to set "-Djava.rmi.server.hostname=localhost" on the distributor JVM so that the clients connect to their local, tunneled port, instead of the port on the actual distributor host, which is blocked. This creates a problem for the workers, though, because they need to connect to the distributor directly, but because of the "localhost" redirection they behave like clients and try to connect to a port on their own host, which is not available, because I'm not tunneling on the workers (it is impractical). Now, if I could connect to a remote object directly by giving the hostname and port, I could do away both with the registry on the distributor and the "localhost" hack, and make the workers connect properly. How do I do that? Or is there a different solution to this problem?

  • Redirected wikipedia request

    - by Le_Coeur
    Hi people, i need to write a program, that can redirect's http://localhost:8080 to en.wikipedia.org, it seems to be easy, but i have some problems(only with wikipedia with another sites works good). I make url to wikipedia: URL url = new URL("http", "en.wikipedia.org", 80, "/wiki"); than URLConnection, extract headers, and when i want connection.getInputStream(), i received message 404 Not Found. So i have tried some hack for host header, because in this way host header is localhost:8080, therefor i have tried to change host header to wikipedia, and it works, but after request in browser http://localhost:8080 wikipedia opens, but url in browser changes to en.wikipedia.org, but i want proceed with localhost :)

  • How to find where a library is used across multiple pom files

    - by Pablojim
    We have multiple maven projects depending on on our own common libraries. When we upgrade a library it would be useful to quickly find out which projects have a dependency on the library (and might need to use the new version) Obviously I can manually look in all the pom files or write a script to do it but this is less than ideal. Are there any tools that provide this functionality. e.g. a hudson plugin, Nexus, artifactory etc?

  • Multi-module Maven build

    - by Don
    Hi, My project has a fairly deep graph of Maven modules. The root POM has the following plugin configured <plugins> <plugin> <groupId>org.jvnet</groupId> <artifactId>animal-sniffer</artifactId> <version>1.2</version> <configuration> <signature> <groupId>org.jvnet.animal-sniffer</groupId> <artifactId>java1.4</artifactId> <version>1.0</version> </signature> </configuration> </plugin> </plugins> If I invoke this target from the command line in the root directory via: mvn animal-sniffer:check Then it works fine as long as the current module extends (either directly or indirectly) from the root POM. However there are many children (or grandchildren) of the root module, which do not inherit from that module's POM. In this case, the goal fails because it cannot find the necessary configuration [ERROR] BUILD ERROR [INFO] ------------------------------------------------------------------------ [INFO] One or more required plugin parameters are invalid/missing for 'animal-sniffer:check' [0] Inside the definition for plugin 'animal-sniffer' specify the following: <configuration> ... <signature>VALUE</signature> </configuration>. When configuring this plugin in the root module, is there any way to exclude a list of sub-modules either by name, or by packaging type? Thanks, Donal

  • How to specify a different column for a @Inheritance JPA annotation

    - by Cue
    @Entity @Inheritance(strategy = InheritanceType.JOINED) public class Foo @Entity @Inheritance(strategy = InheritanceType.JOINED) public class BarFoo extends Foo mysql> desc foo; +---------------+-------------+ | Field | Type | +---------------+-------------+ | id | int | +---------------+-------------+ mysql> desc barfoo; +---------------+-------------+ | Field | Type | +---------------+-------------+ | id | int | | foo_id | int | | bar_id | int | +---------------+-------------+ mysql> desc bar; +---------------+-------------+ | Field | Type | +---------------+-------------+ | id | int | +---------------+-------------+ Is it possible to specify column barfo.foo_id as the joined column? Are you allowed to specify barfoo.id as BarFoo's @Id since you are overriding the getter/seeter of class Foo? I understand the schematics behind this relationship (or at least I think I do) and I'm ok with them. The reason I want an explicit id field for BarFoo is exactly because I want to avoid using a joined key (foo _id, bar _id) when querying for BarFoo(s) or when used in a "stronger" constraint. (as Ruben put it)

  • Problem at JUnit test with generics

  • Custom annotations to configure tests

    - by ace
    First of al let me start off by saying I think custom annotations can be used for this but i'm not totally sure. I would like to have a set of annotations that I can decorate some test classes with. The annotations would allow me to configure the test for different environments. Example: public class Atest extends BaseTest{ private String env; @Login(environment=env) public void testLogin(){ //do something } @SignUp(environment=env) public void testSignUp(){ //do something } } The idea here would be that the login annotation would then be used to lookup the username and password to be used in the testLogin method for testing a login process for a particular environment. So my question(s) is this possible to do with annotations? If so I have not been able to find a decent howto online to do something like this. Everything out there seems to be your basic here's how to do your custom annotations and a basic processor but I haven't found anything for a situation like this. Ideas?

  • opengl - Rendering multiple cubes

This obviously has to do with gltranslatef, but I don't know why that isn't working. My question is, how do I render multiple cubes at once? Are there any tutorials out there on voxel engines? Sorry for the horrible code, I realize I probably need a array to do this. I'm quite new at opengl.

  • Why is BorderLayout calling setSize() and setBounds()?

    - by ags
    I'm trying to get my head around proper use of the different LayoutManagers to make my GUI design skills more efficient and effective. For me, that usually requires a detailed understanding of what is going on under the hood. I've found some good discussion of the interaction and consequences of a Container using BorderLayout containing a Container using FlowLayout. I understand it for the most part, but wanted to confirm my mental model and to do so I am looking at the code for BorderLayout. In the code snippet below taken from BorderLayout.layoutContainer(), note the calls to the child Component's setSize() method followed by setBounds(). Looking at the source for these methods of Component, setSize() actually calls setBounds() with the current values for Component.x and Component.y. Why is this done (and not entirely redudant?) Doesn't the setBounds() call completely overwrite the results of the setSize() call? if ((c=getChild(NORTH,ltr)) != null) { c.setSize(right - left, c.height); Dimension d = c.getPreferredSize(); c.setBounds(left, top, right - left, d.height); top += d.height + vgap; } I'm also tring to understand where/when the child Component's size is initially set (before the LayoutManager.layoutContainer() method is called). Finally, this post itself raises a "meta-question": in a situation like this, where the source is available elsewhere, is the accepteed protocol to include the entire method? Or some other way to make it easier for folks to participate in the thread? Thanks.

  • How can I remove a JPanel from a JFrame?

    - by Roman
    Recently I asked here how to add a new JPanel to JFrame. The answer helped me to get a working code. But not I have a related question: "How can I remove an old JPanel". I need that because of the following problem. A new JPanel appears appears when I want (either time limit is exceeded or user press the "Submit" button). But in several seconds some element of the old JPanel appears together with the component of the new JPanel. I do not understand why it happens. I thought that it is because I have to other threads which update the window. But the first thread just add the old panel once (so, it should be finished). And in the second thread I have a loop which is broken (so, it also should be finished). Here is my code: private Thread controller = new Thread() { public void run() { // First we set the initial pane (for the selection of partner). SwingUtilities.invokeLater(new Runnable() { public void run() { frame.getContentPane().add(generatePartnerSelectionPanel()); frame.invalidate(); frame.validate(); } }); // Update the pane for the selection of the parnter. for (int i=40; i>0; i=i-1) { final int sec = i; SwingUtilities.invokeLater(new Runnable() { public void run() { timeLeftLabel.setText(sec + " seconds left."); } }); try {Thread.sleep(1000);} catch (InterruptedException e) {} if (partnerSubmitted) {break;} } // For the given user the selection phase is finished (either the time is over or form was submitted). SwingUtilities.invokeLater(new Runnable() { public void run() { frame.getContentPane().add(generateWaitForGamePanel()); frame.invalidate(); frame.validate(); } }); } };
