  • Difference between the List and Enumeration

    - by harigm
    I have a written a method to get all the records and return in the List Type, but I got out of memory error. So I changed return type from List to Enumeration, in the method, instead of ArrayList, uses Vector and return vector.elements at the end of the method. It works without any error. but I did not understand why. Could someone explain Why this Enumeration worked?

  • Piano Keys using GridLayout (or Something Else)

    - by yar
    I am creating a container of JComponents which will look like a piano keyboard. The black keys look like this (Groovy) def setBlackNotes(buttons) { def octaves = (int)(buttons.size() / 5) def gridLayout = new GridLayout(1, octaves*7); def blackNotePanel = new JPanel(gridLayout) this.add blackNotePanel def i = 0 octaves.times { 2.times { blackNotePanel.add buttons[i++] } blackNotePanel.add Box.createHorizontalBox() 3.times { blackNotePanel.add buttons[i++] } blackNotePanel.add Box.createHorizontalBox() } } Which is just what I need, and looks like this: but then I'd like to move this over to the right by half-a-key width. All of my attempts to move the blackNotePanel over by an arbitrary width -- wrapping it a BorderLayout, a MigLayout, etc. -- have failed or changed the spacing of the GridLayout radically. Any suggestions on how to move this over to the right by an arbitrary amount in pixels?

  • 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.

  • 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!

  • Getters and Setters are bad OO design?

    - by Dan
    Getters and Setters are bad Briefly reading over the above article I find that getters and setters are bad OO design and should be avoided as they go against Encapsulation and Data Hiding. As this is the case how can it be avoided when creating objects and how can one model objects to take this into account. In cases where a getter or setter is required what other alternatives can be used? Thanks.

  • Regarding Toplink Fetching Policy

    - by Chandu
    Hi, I'm working for a Swing Project and the technologies used are netbeans with Toplink essentials, mysql. The Problem I'm facing is the entity object dosn't get updated after insertions take place while calling a getter collection of the foreign key property. Ex: I have 2 tables Table1,Table2. I have sno column, id column as a primary key in Table1 & is Foreign Key in Table2. Through find method I just get the particular sno object(existed in table 1) set some values persisted to table2 & committed the transaction. When I select the same sno object through find method & gets its collection from Table2 through the getTable2Collection() of the bean(as it is already created in bean by toplink essential) I'm unable to get the latest added record except that all other records of it are displayed. After I close the application & opening it then the new record gets reflected while calling the same sno through the above process. I came to know that this is a kind of lazy fetching and there should be some way of fetch policy to be changed to make the entity object get updated with the changes. So Please help me in this regard. Regards, Chandu

  • Spring: PropertyPlaceHolderConfigurer to set values for non-string/integer properties

    - by babyangel86
    Hi, All the examples I have seen where the PropertyPlaceHolderConfigurer is used seem to be setting simple values like Strings and ints. How do you use the PPC to set the values of classes. E.g. If i had a class signature Source(String name, DistributionSample batch, DistributionSample delay) How would I go about setting the batch and delay properties. There is also a small catch. DistributionSample is an abstract class. On the bright side, The class that is using the propertyPlaceHolder knows the beanName of the "Solid" class that needs to be instantiated. Any help would be much appreciated.

  • What's the correct way to read an inputStream into a node property in JCR 2?

    - by Stuart
    In JCR 1 you could do: final InputStream in = zip.getInputStream(zip.getEntry(zipEntryName)); node.setProperty(JcrConstants.JCR_CONTENT, in); But that's deprecated in JCR 2 as detailed at http://www.day.com/maven/jsr170/javadocs/jcr-2.0/javax/jcr/Node.html#setProperty%28java.lang.String,%20java.io.InputStream%29 That says I should be using node.setProperty(String, Binary) but I don't see any way to turn my inputStream into a Binary. Can anyone point me to docs or example code for this?

  • Repeated Scene Trees (Java3d / OpenGL)

    - by Jim
    Hello, I want to make a 3d scene that loops around on its self. That is to say, if you keep going in any direction, you will loop back to the other side. My current implementation is so bad, it's embarrassing to admit to it. I redraw the each change twenty-seven times, to make a 3x3x3 scene cube. When the user reaches the end of the middle cube, I jump them over to the other side. Maintaining consistency (let alone performance) is a nightmare. Total Disaster. This doesn't seem like it would be an unusual request, so I'm wondering if anyone knows of a more legit solution. Thanks!

  • Android Apps not working in emulator

    - by Mohit Deshpande
    None of my apps work in the emulator. I am running Ubuntu 9.10 and everytime I try to access my UI, the app crashes. All I get is an "Sorry! The application ... has stopped unexpectedly". For EVERY app this happens. package com.mohit.helloandroid; import android.app.TabActivity; import android.content.Intent; import android.content.res.Resources; import android.os.Bundle; import android.widget.TabHost; public class HelloAndroid extends TabActivity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Resources res = getResources(); //Resource object to get drawables TabHost tabHost = getTabHost(); //The activity tabhost TabHost.TabSpec spec; //Reusable tab spec Intent intent; intent = new Intent().setClass(this, HelloAndroid.class); spec = tabHost.newTabSpec("artists").setIndicator("Artists", res .getDrawable(R.drawable.tab_artists)) .setContent(intent); tabHost.addTab(spec); } } I don't know how this code could possibly throw a message like that.

  • Is it possible to use ActiveObjects (or another ORM) with an embedded database & JWS technology ?

    - by phmr
    I would like to embed a database in my JWS application. As a matter of fact I have to use HSQL or SQLite. Hibernate may support (HSQL or SQLite, does it ?) but the workflow is rather complex for my application but maybe it's the way to go for my needs. In ActiveObjects database shoould be "linked" to by a path because of JDBC, but is it possible to specify a database that is inside a JAR and how ?

  • 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!
