  • 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.

  • I18n - JSF variable value translation

    - by Yurish
    Hi! I am using Bundle Internationalization in my project. I have initialized bundle via <f:loadBundle basename="ui.all.bundles.AppResources_en" var="msg"/> When i need to translate some text, i am using a key to resourceBundle, to get a value of it, for example: #{msg.someText}. But, now i want to translate text, which key is a value of another variable. For example: I have variable String textToTransl. It`s value is status_booked. In my AppResources is defined, that status_booked means "It is booked!", so, when i am pointing it to #{msg.textToTransl} i need to see "It is booked!" How can i make it work?

  • Doubt about instance creation by using Spring framework ???

    - by Arthur Ronald F D Garcia
    Here goes a command object which needs to be populated from a Spring form public class Person { private String name; private Integer age; /** * on-demand initialized */ private Address address; // getter's and setter's } And Address public class Address { private String street; // getter's and setter's } Now suppose the following MultiActionController @Component public class PersonController extends MultiActionController { @Autowired @Qualifier("personRepository") private Repository<Person, Integer> personRepository; /** * mapped To /person/add */ public ModelAndView add(HttpServletRequest request, HttpServletResponse response, Person person) throws Exception { personRepository.add(person); return new ModelAndView("redirect:/home.htm"); } } Because Address attribute of Person needs to be initialized on-demand, i need to override newCommandObject to create an instance of Person to initiaze address property. Otherwise, i will get NullPointerException @Component public class PersonController extends MultiActionController { /** * code as shown above */ @Override public Object newCommandObject(Class clazz) thorws Exception { if(clazz.isAssignableFrom(Person.class)) { Person person = new Person(); person.setAddress(new Address()); return person; } } } Ok, Expert Spring MVC and Web Flow says Options for alternate object creation include pulling an instance from a BeanFactory or using method injection to transparently return a new instance. First option pulling an instance from a BeanFactory can be written as @Override public Object newCommandObject(Class clazz) thorws Exception { /** * Will retrieve a prototype instance from ApplicationContext whose name matchs its clazz.getSimpleName() */ getApplicationContext().getBean(clazz.getSimpleName()); } But what does he want to say by using method injection to transparently return a new instance ??? Can you show how i implement what he said ??? ATT: I know this funcionality can be filled by a SimpleFormController instead of MultiActionController. But it is shown just as an example, nothing else

  • Hibernate: how to maintain insertion order

    - by jwaddell
    I have a list of entities where creation order is important, but they do not contain a timestamp to use for sorting. Entities are added to the end of the list as they are created so they will be ordered correctly in the list itself. After persisting the list using Hibernate the entities appear in the database table in the order that they were created. However when retrieving the list using a new Hibernate session the list is now in reverse order of insertion/creation. Is this expected behaviour? Is there any way to retrieve the list in the same order as it appears in the table? The primary key is a UUID, and the list of entities should always have been created on the same IP address and JVM. This mean sorting by UUID is a possibility but I'd rather not make assumptions. Another possibility is if the list is guaranteed to always come out in reverse order I could always just work through it backwards.

  • Encountering NullPointerException when trying to add polynoms

    - by Ayler Cruz
    I need to add two polynomials, which is composed of two ints. For example, the coefficient and the exponent 3x^2 would be constructed using 3 and 2 as parameters. I am getting a NullPointerException but I can't figure out why. Any help would be appreciated! public class Polynomial { private Node poly; public Polynomial() { } private Polynomial(Node p) { poly = p; } private class Term { int coefficient; int exponent; private Term(int coefficient, int exponent) { this.coefficient = coefficient; this.exponent = exponent; } } private class Node { private Term data; private Node next; private Node(Term data, Node next) { this.data = data; this.next = next; } } public void addTerm(int coeff, int exp) { Node pointer = poly; if (pointer.next == null) { poly.next = new Node(new Term(coeff, exp), null); } else { while (pointer.next != null) { if (pointer.next.data.exponent < exp) { Node temp = new Node(new Term(coeff, exp), pointer.next.next); pointer.next = temp; return; } pointer = pointer.next; } pointer.next = new Node(new Term(coeff, exp), null); } } public Polynomial polyAdd(Polynomial p) { return new Polynomial(polyAdd(this.poly, p.poly)); } private Node polyAdd(Node p1, Node p2) { if (p1 == p2) { Term adding = new Term(p1.data.coefficient + p2.data.coefficient, p1.data.exponent); p1 = p1.next; p2 = p2.next; return new Node(adding, null); } if (p1.data.exponent > p2.data.exponent) { p2 = p2.next; } if (p1.data.exponent < p2.data.exponent) { p1 = p1.next; } if (p1.next != null && p2.next != null) { return polyAdd(p1, p2); } return new Node(null, null); } }

  • Is it against best practice to throw Exception on most JUnit tests?

    - by Chris Knight
    Almost all of my JUnit tests are written with the following signature: public void testSomething() throws Exception My reasoning is that I can focus on what I'm testing rather than exception handling which JUnit appears to give me for free. But am I missing anything by doing this? Is it against best practice? Would I gain anything by explicitly catching specific exceptions in my test and then fail()'ing on them?

  • how to Solve the "Digg" problem in MongoDB

    - by user193116
    A while back,a Digg developer had posted this blog ,"http://about.digg.com/blog/looking-future-cassandra", where the he described one of the issues that were not optimally solved in MySQL. This was cited as one of the reasons for their move to Cassandra. I have been playing with MongoDB and I would like to understand how to implement the MongoDB collections for this problem From the article, the schema for this information in MySQL : CREATE TABLE Diggs ( id INT(11), itemid INT(11), userid INT(11), digdate DATETIME, PRIMARY KEY (id), KEY user (userid), KEY item (itemid) ) ENGINE=InnoDB DEFAULT CHARSET=utf8; CREATE TABLE Friends ( id INT(10) AUTO_INCREMENT, userid INT(10), username VARCHAR(15), friendid INT(10), friendname VARCHAR(15), mutual TINYINT(1), date_created DATETIME, PRIMARY KEY (id), UNIQUE KEY Friend_unique (userid,friendid), KEY Friend_friend (friendid) ) ENGINE=InnoDB DEFAULT CHARSET=utf8; This problem is ubiquitous in social networking scenario implementation. People befriend a lot of people and they in turn digg a lot of things. Quickly showing a user what his/her friends are up to is very critical. I understand that several blogs have since then provided a pure RDBMs solution with indexes for this issue; however I am curious as to how this could be solved in MongoDB.

  • Android how to create notification that resumes activity

    - by Adam Praiswater
    I a have a notification in a receiver that fires off fine, but it restarts the activity (thus clearing the edittexts and resetting the toggle button) How can i set it so that when its tapped on it resumes the activity rather that clearing and resetting everything? My current code doesnt work. Current Code String currentDateTimeString = DateFormat.getDateTimeInstance().format(new Date()); Intent intenti= new Intent(context, Locator.class); intenti.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_SINGLE_TOP); PendingIntent contentIntent = PendingIntent.getActivity(context, 0, intenti, 0); NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context) .setSmallIcon(R.drawable.xxxxxxnotifyicon) .setContentTitle("xxxxxxx Link") .setContentText("Auto Check In Complete at " + currentDateTimeString); mBuilder.setContentIntent(contentIntent); mBuilder.setDefaults(Notification.DEFAULT_SOUND); mBuilder.setAutoCancel(true); NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE); mNotificationManager.notify(1, mBuilder.build());

  • Search the Quartz maps

    - by user197127
    Hi, I would like to store some properties in the quartz datastore (jdbc) and then be able to find all triggers/jobs that match. E.g. store the user id related to a trigger and then query like user_id=555. Previously, I used to query the database directly but this is naturally not a good way. Anyone has another suggestion on how to accomplish this? Thanks.

  • 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?

  • 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.

  • 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; } }

  • Spring security and Struts 2

    - by Thanksforfish
    I have a struts2 action with an @Secured({"ROLE_ADMIN"}) to secure the execute method. In the execute method i assign a message to a member variable of the action, then return SUCCESS and end up on the jsp page. On the page I retrieve the actions member variable with <sroperty. private String greeting; public String execute() throws Exception { this.greeting="Hello"; return SUCCESS; } // getters and setters for greeting ... <s:property value="greeting" /> The problem is when the secured annotation is present the jsp shows nothing for the member variable but when @Secured is removed the whole thing behaves properly and shows the message that was set into the member variable. It appears that the actual security is working ok but when enabled via the annotation the member variable (or maybe the instance of the action) is not making its way onto the value stack. I cant see any error messages.

  • Displaying same image multiple times at different locations in a web page using JavaScript or CSS

    - by Joe B
    I’m looking to create a web page with 6 coupons on it, two per line in a web space of 1275 X 1650. Each coupon space will consist of a different image. The problem is I will be creating 20 such web pages that will have these coupons on them. Now some of the same images will appear in different locations/positions on the various web pages. Is there a way to update the same image that appear in different locations/positions at the same time? And what language is used to complete this? I’ve tried CSS but it don’t think it’s possible. So should I be using JavaScript.

  • Rounding up milliseconds when printing with Joda Time

    - by RoToRa
    I'm implementing a count-down using Joda Time. I only need a display accuracy of seconds. However when printing the time, the seconds are displayed as full seconds, so when the count down reaches, for example, 900ms, then "0" seconds is printed, but as a count-down it would make more sense to display "1" second, until the time actually reaches 0ms. Example: void printDuration(Duration d) { System.out.println( d.toPeriod(PeriodType.time()).toString( new PeriodFormatterBuilder().printZeroAlways().appendSeconds().toFormatter() ) ); } printDuration(new Duration(5000)); // Prints "5" => OK printDuration(new Duration(4900)); // Prints "4" => need "5" printDuration(new Duration(1000)); // Prints "1" => OK printDuration(new Duration(900)); // Prints "0" => need "1" printDuration(new Duration(0)); // Prints "0" => OK Basically I need to the seconds to be display rounded up from milliseconds and not rounded down. Is there a way to achieve this with Joda without needing to write my own formatter?
