  • Why is Log4j rootLogger not filtering log events according to event level?

    - by Derek Mahar
    Why is the Log4j rootLogger in my application not filtering log events according to level? In my log4j.properties, I have several loggers: log4j.rootLogger=info,stdout log4j.logger.com.name.myapp=debug,myapp log4j.logger.org.castor=debug,castor log4j.logger.org.exolab.castor=debug,castor log4j.logger.org.hibernate=debug,hibernate log4j.logger.org.springframework=debug,spring Each of the loggers receive and record numerous log events at levels DEBUG and above, which is what I expect. The rootLogger, however, despite being set to level INFO, is displaying all of these events, too, including the DEBUG events, which is not what I expect. Instead, I would expect it to filter the DEBUG events, but display only the events at level INFO and higher (WARN, ERROR, and FATAL). Why is rootLogger displaying all of the events?

  • Spring-Security http-basic auth in addition to other authentication types

    - by Keith
    I have a pretty standard existing webapp using spring security that requires a database-backed form login for user-specific paths (such as /user/**), and some completely open and public paths (such as /index.html). However, as this webapp is still under development, I'd like to add a http-basic popup across all paths (/**) to add some privacy. Therefore, I'm trying to add a http-basic popup that asks for a universal user/pass combo (ex admin/foo) that would be required to view any path, but then still keep intact all of the other underlying authentication mechanisms. I can't really do anything with the <http> tag, since that will confuse the "keep out the nosy crawlers" authentication with the "user login" authentication, and I'm not seeing any way to associate different paths with different authentication mechanisms. Is there some way to do this with spring security? Alternatively, is there some kind of a dead simple filter that I can apply independently of spring-security's authentication mechanisms?

  • Should integration testing of DAOs be done in an application server?

    - by HDave
    I have a three tier application under development and am creating integration tests for DAOs in the persistence layer. When the application runs in Websphere or JBoss I expect to use the connection pooling and transaction manager of those application servers. When the application runs in Tomcat or Jetty, we'll be using C3P0 for pooling and Atomikos for transactions. Because of these different subsystems, should the DAO's be tested in a fully configured application server environment or should we handle those concerns when integration testing the service layer? Currently we plan on setting up a simple JDBC data source with non-JTA (i.e. resource-local) transactions for DAO integration testing, thus no application server is involved....but this leaves me wondering about environmental problems we won't uncover.

  • How could I get an .ear's filesize at runtime?

    - by adam
    I started out attempting to do this with the Length ant task, but realized that that would be done before the ear is packaged. Packaging the ear, then checking the file size, and then placing it in the ear would effect the size of the ear. Is there a way to get the ear's size programmatically at run-time? Or perhaps an MBean that would have that information?

  • Unable to set mouse cursor JLayeredPane

    - by Ones3k2
    I'm running into a problem that I can't seem to figure out nor find the answer anywhere on the web. I've got a JLayeredPane and when it only has one child Panel I am able to correctly set the cursor using setCursor(). The cursor shows up and everything is fine. But when I add an additional JPanel into the JLayeredPane the cursor no longer shows up for example this works: m_layeredPane = new JLayeredPane(); m_layeredPane.setLayout(new WBLayoutManager()); m_layeredPane.add(m_mediaPanel, new Integer(0)); // m_layeredPane.add(m_whiteboardPanel, new Integer(1)); m_layeredPane.setCursor(Cursor.getPredefinedCursor(Cursor.HAND_CURSOR)); // WORKS but this doesn't: m_layeredPane = new JLayeredPane(); m_layeredPane.setLayout(new WBLayoutManager()); m_layeredPane.add(m_mediaPanel, new Integer(0)); m_layeredPane.add(m_whiteboardPanel, new Integer(1)); m_layeredPane.setCursor(Cursor.getPredefinedCursor(Cursor.HAND_CURSOR)); // FAILS Anyone know how i can get custom cursors working within a JLayeredPane

  • Create NinePatch at Runtime

    - by Pedro Lopes
    Hello everybody! I have a business need to create the NinePatchDrawable objects at runtime, this is, an exterior .png image is received from a server and it has to be applied in a button's background (for example) as a nine patch. I have tried to create the NinePatchDrawable object, but the constructor asks me for a "byte[] chuck" that describes the patch. The thing is, I have no idea on how to build this chunck from a bitmap that does not have the 9patch information in it. Any ideas on this topic? Am I seeing the problem from a wrong perpective? Thanks!

  • In Intellij, how can I get a List on the left hand side when I extract a variable that's an ArrayList?

    - by tieTYT
    As an example, if I extract a variable from this: return new ArrayList<CrudTestData<Foo>>(); It will turn the code into this: ArrayList<CrudTestData<Foo>> list = new ArrayList<CrudTestData<Foo>>(); return list; How can I automatically get a list on the left hand side like this? List<CrudTestData<Foo>> list = new ArrayList<CrudTestData<Foo>>(); return list; Theoretically, Intellij should know to use a List instead of a Collection because the method returns a List.

  • Updating position of JSlider Swing

    - by GLRockwell
    My apologies for posting tons of questions as of late. I'm trying to get a JSlider to update its position based on a constantly updating variable. The setValue(n) method doesn't seem to work. Is there any alternative? We're using this as a time marker for a music player.

  • Autocompletion in Eclipse for Roo project

    - by niklassaers
    Hi guys, I've got a Roo project where I've made a couple of entities, and when I load up the project in Eclipse it loads up fine, but if I i.e. make an instance MyEntity entity and then write entity. I don't get any of my properties (i.e. getMyField) in the autocompletion list. If I write entity.getMyField() it compiles fine, that is taken care of by the aspects. How do I enable autocompletion for functions generated by the aspects? Cheers Nik

I can not make TextField and InternalFrame at a time. I want to know the concept. I hope you take my question right.

  • Automatic Hudson CI setup and plugin updates through apt?

    - by aapeli
    Hi! We've used Hudson for quite a while to implement a CI server with all the bells and whistles. The setup is quite straight forward, when installing from the provided RPMs and Debs, but through googling I haven't been able to figure out whether the plugins are installable using apt/rpm or some other package manager? The reason is that I would like to create a (meta)package for Ubuntu which would install and also update both Hudson and all the plugins through the normal upgrade mechanism. At the same time I could create a template setup for other projects, say JavaEE project needs git, cobertura and Chuck Norris plugins, while my Python project needs plugins XXX and YYY. Anybody got such a setup? As a workaround I figured setting up a number of Maven POMs, which would do the init, and later upgrades, but I feel this would require more scripting on the side, which I'm not very eager to do. Any other suggestions for this would also be appreciated.

  • What does this do and why does it require a transaction?

    - by S. Palin
    What does the following code example do and why does it require a transaction? // PersistenceManager pm = ...; Transaction tx = pm.currentTransaction(); User user = userService.currentUser(); List<Account> accounts = new ArrayList<Account>(); try { tx.begin(); Query query = pm.newQuery("select from Customer " + "where user == userParam " + "parameters User userParam"); List<Customer> customers = (List<Customer>) query.execute(user); query = pm.newQuery("select from Account " + "where parent-pk == keyParam " + "parameters Key keyParam"); for (Customer customer : customers) { accounts.addAll((List<Account>) query.execute(customer.key)); } } finally { if (tx.isActive()) { tx.rollback(); } }

  • Are there any simple languages implemented using ANTLR or similar?

    - by etheros
    I'm trying to build a simple interpreted language for learning purposes. I've read countless theory and tutorials on ANTLR and JavaCC, but I can't figure out how to actually make it do something useful. I learn best by "taking something apart and putting it back together again", so, are there any working examples of simple languages implemented with the help of tools such as ANTLR, or similar? Something like the following might be nice: x = 1 if x == 1 print "true"

  • Webapp: safetly update a shared List/Map in the AppContext

    - by al nik
    I've Lists and Maps in my WebAppContext. Most of the time these are only read by multiple Threads but sometimes there's the need to update or add some data. I'm wondering what's the best way to do this without incurring in a ConcurrentModificationException. I think that using CopyOnWriteArrayList I can achieve what I want in terms of - I do not have to sync on every read operation- I can safety update the list while other threads are reading it. Is this the best solution? What about Maps?

  • How to define generic super type for static factory method?

    - by Esko
    If this has already been asked, please link and close this one. I'm currently prototyping a design for a simplified API of a certain another API that's a lot more complex (and potentially dangerous) to use. Considering the related somewhat complex object creation I decided to use static factory methods to simplify the API and I currently have the following which works as expected: public class Glue<T> { private List<Type<T>> types; private Glue() { types = new ArrayList<Type<T>>(); } private static class Type<T> { private T value; /* some other properties, omitted for simplicity */ public Type(T value) { this.value = value; } } public static <T> Glue<T> glueFactory(String name, T first, T second) { Glue<T> g = new Glue<T>(); Type<T> firstType = new Glue.Type<T>(first); Type<T> secondType = new Glue.Type<T>(second); g.types.add(firstType); g.types.add(secondType); /* omitted complex stuff */ return g; } } As said, this works as intended. When the API user (=another developer) types Glue<Horse> strongGlue = Glue.glueFactory("2HP", new Horse(), new Horse()); he gets exactly what he wanted. What I'm missing is that how do I enforce that Horse - or whatever is put into the factory method - always implements both Serializable and Comparable? Simply adding them to factory method's signature using <T extends Comparable<T> & Serializable> doesn't necessarily enforce this rule in all cases, only when this simplified API is used. That's why I'd like to add them to the class' definition and then modify the factory method accordingly. PS: No horses (and definitely no ponies!) were harmed in writing of this question.

  • Hook for redraw event in Blackberry

    - by Bendlas
    Is there a way to add a redraw callback to a live screen object, i.e. not via inheritance? Reasoning: I want to draw an overlay from an extension for widget sdk (substituting defunct position:absolute), so the screen is created by the bbwp stub. I can get it by Ui.getUiEngine().getActiveScreen() and draw on it quite nicely, but I need a way to redraw when appropriate. Note: I've abandoned the approach to push the overlay as a screen, because i couldn't make it transparent / find a way to pass events through.

  • How To Keep Size Of JTextArea constant?

    - by Supereme
    Hi! I'm using an object of JTextArea in my application which deals with sending sms. I've used a DocumentFilter so as to allow only 160 characters to be typed in the textarea but now, I want the size of the textarea to be constant. it goes on increasing if I keep writing on the same line without pressing 'enter' key or even when I keep on pressing only 'enter' key. I tried once using 'scrollbar' too but the problem remains same. Suggest me something over this.

  • Correct way to persist Quartz triggers

    - by davioooh
    I'm quite new to Quartz and now I need to schedule some jobs in Spring Web App. I know about Spring + Quartz integration (I'm using Spring v 3.1.1) but I'm wondering if it's the right way to follow. In particular I need to persist my scheduled tasks in a DB so I can re-initialize them when application is restarted. Are there some utilities provided by Spring scheduling wrapper to do this? Can you suggest me some "well known" approach to follow?

  • JSF hiding exceptions?

    - by bshacklett
    I have a managed bean for a JSF page which is doing JPA calls in the constructor to populate fields in the bean. I'm having a bit of trouble with another call to persist an entity (to populate data for testing). I'm expecting it to throw some sort of exception since it's not working, but I'm not getting anything. Just of the heck of it I tried the following: Query newQuery = em.createQuery("Bad Syntax"); List newList = newQuery.getResultList(); I'd expect an IllegalArgumentException here since the query string is completely invalid, but the page still loads and I don't see any exceptions anywhere. Am I right in expecting this exception? If so, why am I not seeing it?

  • Android file-creation fails.

    - by Alxandr
    I use the following code to create a folder "mymir" and a file ".nomedia" (in the mymir-folder) on the sdcard of an android unit. However, somehow it fails with the exception that the folder the ".nomedia"-file is to be placed in dosn't exist. Here's the code: private String EnsureRootDir() throws IOException { File sdcard = Environment.getExternalStorageDirectory(); File mymirFolder = new File(sdcard.getAbsolutePath() + "/mymir/"); if(!mymirFolder.exists()) { File noMedia = new File(mymirFolder.getAbsolutePath() + "/.nomedia"); noMedia.mkdirs(); noMedia.createNewFile(); } return mymirFolder.getAbsolutePath(); }

  • Creating lots of arrays

    - by Dmitry
    Hello, everybody! May be that is a stupid question. How to create, say, 30 arrays (it doesn't matter of what type, say, char[])? It seems to me that it is not a good idea, to create them one by one by hand. I want to do that using a "for" cycle, but how should I specify identifiers?
