• how to programmatically register an already setup bean to spring context

  - by lisak

  Hey, I'm wondering how one can do that. Afaik there is BeanFactoryPostProcessor interface that let us use BeanDefinitionRegistry.registerBeanDefinition() method before beans within context are initialized. That method accepts only a class / definition. But usually one needs to register a bean that is already set with properties. Otherwise the bean definition registration itself is kinda useless. I don't want to set it up additionally after I get it from context then. When using singleton it's ok, but for prototypes I'd have to set the bean up for each getBean() .

• Is it better to use List or Collection?

  - by Vivin Paliath

  I have an object that stores some data in a list. The implementation could change later, and I don't want to expose the internal implementation to the end user. However, the user must have the ability to modify and access this collection of data. Currently I have something like this: public List<SomeDataType> getData() { return this.data; } public void setData(List<SomeDataType> data) { this.data = data; } Does this mean that I have allowed the internal implementation details to leak out? Should I be doing this instead? public Collection<SomeDataType> getData() { return this.data; } public void setData(Collection<SomeDataType> data) { this.data = new ArrayList<SomeDataType>(data); }

• Deploying CXF web service in weblogic 10.

  - by Rig Veda

  Earlier I used to create a war file out of web service and manually deploy it in weblogic. But now (somehow) weblogic doesn't recognize the web-service. Though the earlier jars continue to work. The WSDL's in both the cases are same. Any help would be welcome. But my question is how does weblogic find the web-service. Is it the WSDL or soemthing else?

• In an ExpandableListView, how can I show one additional line at the end of the child results?

  - by fiXedd

  I have created a custom ExpandableListAdapter and everything works properly. What I'd like to be able to do is in each of the groups add a different type of child to the end. I have tried adding 1 to the getChildrenCount() number and then testing isLastChild in the getChildView() method, but that doesn't seem to work. If a group has three children what I have working looks like this: Group NormalChild NormalChild NormalChild But I'd really like something like this: Group NormalChild NormalChild NormalChild AlternateChild The idea being that the AlternateChild could be a link to more info about the group. Any Ideas? EDIT: ListView has addFooterView() which will allow you to add a footer to a whole ListView... wonder how to add them to the ExpandableListView's children, or if it's even possible

• Strange behaviour with GregorianCalendar

  - by Spark

  I just encountered a strange behaviour with the GregorianCalendar class, and I was wondering if I really was doing something bad. This only appends when the initialization date's month has an actualMaximum bigger than the month I'm going to set the calendar to. Here is the example code : // today is 2010/05/31 GregorianCalendar cal = new GregorianCalendar(); cal.set(Calendar.YEAR, 2010); cal.set(Calendar.MONTH, 1); // FEBRUARY cal.set(Calendar.DAY_OF_MONTH, cal.getActualMaximum(Calendar.DAY_OF_MONTH)); cal.set(Calendar.HOUR_OF_DAY, cal.getActualMaximum(Calendar.HOUR_OF_DAY)); cal.set(Calendar.MINUTE, cal.getActualMaximum(Calendar.MINUTE)); cal.set(Calendar.SECOND, cal.getActualMaximum(Calendar.SECOND)); cal.set(Calendar.MILLISECOND, cal.getActualMaximum(Calendar.MILLISECOND)); return cal.getTime(); // => 2010/03/03, wtf I know the problem is caused by the fact that the calendar initialization date is a 31 day month ( may ), which mess with the month set to february (28 days). The fix is easy ( just set day_of_month to 1 before setting year and month ), but I was wondering is this really was the wanted behaviour. Any thoughts ?

• Automated UAT/functional tests on Swing applications without source code

  - by jas

  Our team is now working on a big Swing application. Our job basically focuses on writing extensions to the existing framework. A typical job would be adding a new panel/ or adding a new tab with some extra functionalities that suit our need. It seems FEST can help a lot in terms of unit-test our code. I am going to try it out this week. But the question here is if there is a way to do automated functional testing on the whole application. In another word, we do not only need to test our code but also the framework. After all, UAT is the most important part. I am currently considering decompiling the jar files we got into source code then we can identify the components and then use FEST. So, before I get started to give this approach a shot, I think I just ask for ideas and inspirations here. There must be people who have done similar things before. Would be nice if I could learn from the veterans who fought against this before . Thanks,

• SoundPool repeating issue for Samsung Galaxy S3

  - by Alaa Eldin

  I'm trying to play a background sound for my application, I use SoundPool class, my problem is that, sound plays well only when I set the loop parameter with zero value, but it doesn't work for any other value. My code for initialization is: soundpool = new SoundPool(4, AudioManager.STREAM_MUSIC, 0); soundsMap = new HashMap<Integer, Integer>(); soundsMap.put(1, soundpool.load(this, R.raw.soundfile_1, 1)); soundsMap.put(2, soundpool.load(this, R.raw.soundfile_2, 1)); my code for playing is soundpool.play(1, 0.9f, 0.9f, 1, -1, 1f); as I mentioned sound works when I put (0) instead of (-1) for the loop value, anyone has any idea why (-1) or any value other than (0) doesn't work (there is no output sound) ?

• optimistic locking batch update

  - by Priit

  How to use optimistic locking with batch updates? I am using SimpleJdbcTemplate and for single row I can build update sql that increments version column value and includes version in WHERE clause. Unfortunately te result int[] updated = simpleJdbcTemplate.batchUpdate does not contain rowcounts when using oracle driver. All elements are -2 indicating unknown rowcount. Is there some other, more performant way of doing this than executing all updates individually? These batches contain an average of 5 items (only) but may be up to 250.

• How to remove Modules from a Intellij Maven Project permanently?

  - by herpnderpn

  I am currently working on a larger scale Maven-based project in IntelliJIdea 12.1.6 Ultimate. I have been working with IntelliJIdea since about 5 months. An included module has dependencies on another module. The dependent module's source was also part of my project until recently. Since I removed the dependent module from my project, I get compile errors whenever I am trying to compile the source without maven. The pom.xml of removed modules in Intellij seem to be placed onto the Settings-Maven-Ignored Files. I cant seem to remove it from there, only check or uncheck it. It's not possible to include the module again since IntelliJ will say its still under Ignored Files. 2 ways allow me to compile again: Uncheck the pom from Ignored files, which will include the module again in my project. Or delete the source of the dependent project, so my project will load the dependent module from the maven repository. But whenever I update my project from svn, the source of the dependent module is restored (I don't know why this even happens since its not part my project) and the cycle begins anew. I googled this for a while since it gets really annoying. It became a problem with several excluded modules. I could rebuild the intellij-project but since a lot of IntelliJ settings were made (not related to the problem) I would rather solve this. Any help is appreciated, I guess I must be missing something

• PulpCore OGG music playback - can't loop as soon as I animate the musicVolume property

  - by Peter Perhác

  I have been experimenting with PulpCore for about a week or so and I am enjoying it very much but today I ran into a problem that I can't quite figure out. Sound bgMusic = Sound.load("music/music.ogg"); Playback musicPlayback; ... musicVolume = new Fixed(0.75); musicPlayback = bgMusic.loop(musicVolume); //TODO figure out why it's NOT looping when volume is animated // musicVolume.animate(0, musicVolume.get(), FADE_IN_TIME); This code, for as long as the last line is commented out, plays the music.ogg again and again in an endless loop (which I can stop by calling stop on the Playback object returned from loop(). However, I would like the music to fade in smoothly, so following the advice of the PulpCore API docs, I added the last line which will create the fade-in but the music will only play once and then stop. I wonder why is that? Here is a bit of the documentation: Playback pulpcore.sound.Sound.loop(Fixed level) Loops this sound clip with the specified volume level (0.0 to 1.0). The level may have a property animation attached. Parameters: level Returns: a Playback object for this unique sound playback (one Sound can have many simultaneous Playback objects) or null if the sound could not be played. So what could be the problem? I repeat, with the last line, the sound fades in but doesn't loop, without it it loops but starts with the specified 0.75 volume level.

• Hierarchical object model with property inheritance and event bubbling?

  - by Winston Fassett

  I'm writing a document-based client application and I need a DOM or WPF-like, but non-visual model that: Is a tree composed of elements Can accept an unlimited number of custom properties that get/set any CLR type, including collections. Can inherit their values from their parent Can inherit their default values from an ancestor Can be derived/calculated from other properties, ancestors, or descendants Support event bubbling / tunneling There will be a core set of properties but other plugins may add their own or even create custom documents Supports full inspection by the owning document in order to persist the tree and attributes in an XML format. I realize that's a tall order but I was really hoping there would be something out there to help me get started. Unfortunately WPF DependencyObjects are too closed, proprietary, and coupled to WPF to be of any use as a document model. My needs also have a strong resemblance to the HTML DOM but I haven't been able to find any clean DOM implementations that could be decoupled from HTML or ported to .NET. My current platform is .NET/C# but if anyone knows of anything that might be useful for inspiration or embedding, regardless of the platform, I'd love to know.

• What happens to my PriorityQueue if my Comparator throws an exception while it's busy bubbling up or

  - by nieldw

  Hi, I'm trying order pairs of integers ascendantly where a pair is considered less than another pair if both its entries are strictly less than those of the other pair, and larger than the other pair if both its entries are strictly larger than those of the other pair. All other cases are considered incomparable. They way I want to solve this is by defining a Comparator that implements the above, but will throw an exception for incomparable cases, and provide that to a PriorityQueue. Of course, while inserting a pair the priority queue does several comparisons while bubbling the new entry up to its correct position in the heap, and many of these will be comparable. But it may happen during the bubbling process that a pair is encountered with which this new pair is incomparable, and an exception will be thrown. If this happens, what will be the state of the PriorityQueue? Will the pair I was trying to insert sit in the heap at the last position it was in before the exception was thrown? If I use the PriorityQueue's remove(Object o) method, will the PriorityQueue be restored to a consistent state? Thanks

• How can I use Hibernate Criteria's to query nested tables?

  - by cbmeeks

  I've looked all over SO and Google but I guess I'm not using the right search terms or something. Anyway, say I have three tables: Companies ----------------------------------------- id name user_id Users ----------------------------------------- id username usertype_id UserTypes ----------------------------------------- id typeofuser So ACME would be a company, it would have a user Moe and Moe would be a usertype of Stooge. In SQL, I would do something like: select * from companies c join users u on (u.id = c.user_id) join usertypes ut on (ut.id = u.usertype_id) where ut.typeofuser = 'Stooge' But I can't seem to figure out how to do that in a Criteria. I have tried: Criteria crit = io.getSession().createCriteria(Company.class); List<Company> list = crit.createCriteria("users") .createCriteria("usertypes") .add(Restriction.eq("typeofuser", "Stooge").list(); But I get back way too many records. And the results don't even come close to being accurate. I've also tried: Criteria crit = io.getSession().createCriteria(Company.class); List<Company> list = crit.createAlias("users", "u") .createAlias("u.usertypes", "ut") .add(Restriction.eq("ut.typeofuser", "Stooge").list(); Seems to bring back the exact same result set. I actually have read the user manual. And when I nest only one level deep (ie, searching by users is fine) but when I get two layers deep, I can't quite get it. And the manual is no help. I just can't relate cats and kittens to business objects. Maybe they should use cats, kittens and fleas? :-/ Thanks for any suggestions.

• Setting a value into a object using reflection

  - by marionmaiden

  Hello I have an object that has a lot of attributes, each one with it's getter and setter. Each attribute has a non primitive type, that I don't know at runtime. For example, what I have is this: public class a{ private typeA attr1; private typeB attr2; public typeA getAttr1(){ return attr1; } public typeB getAttr2(){ return attr2; } public void setAttr1(typeA at){ attr1 = at; } public void setAttr2(typeB at){ attr2 = at; } } public class typeA{ public typeA(){ // doesn't matter } } public class typeB{ public typeB(){ // doesn't matter } } So, using reflection, I obtained the setter method for an attribute. Setting a value in the standard way is something like this: a test = new a(); a.setAttr1(new typeA()); But how can I do this using reflection? I already got the setAttr1() method using reflection, but I don't know how to create a new typeA object to be inserted in the setter.

• How do I left join tables in unidirectional many-to-one in Hibernate?

  - by jbarz

  I'm piggy-backing off of http://stackoverflow.com/questions/2368195/how-to-join-tables-in-unidirectional-many-to-one-condition. If you have two classes: class A { @Id public Long id; } class B { @Id public Long id; @ManyToOne @JoinColumn(name = "parent_id", referencedColumnName = "id") public A parent; } B - A is a many to one relationship. I understand that I could add a Collection of Bs to A however I do not want that association. So my actual question is, Is there an HQL or Criteria way of creating the SQL query: select * from A left join B on (b.parent_id = a.id) This will retrieve all A records with a Cartesian product of each B record that references A and will include A records that have no B referencing them. If you use: from A a, B b where b.a = a then it is an inner join and you do not receive the A records that do not have a B referencing them. I have not found a good way of doing this without two queries so anything less than that would be great. Thanks.

• Spring ROO issue with UrlRewrite in STS (eclipse)

• Accessing the value of a Richfaces calendar during validation.

Where is the value that appears in the text box of the richfaces calendar component?

• Why encodeXxx methods in UIComponent accept FacesContext parameter?

  - by Roman

  I haven't ever before created custom component in jsf so I've noticed it only now that methods like encodeBegin(), encodeEnd() etc accept FacesContext parameter. FacesContext instance can usually be received with FacesContext.getCurrentInstance(). So, I wonder whether these methods have FacesContext parameter just for convenience or some different objects can be passed there (maybe from external resources..). If the latter is possible then could you give an example pls.

• what pattern to use for multi-argument method?

  - by Omid S

  I have a method with the following signature: foo (Sample sample, Aliquot aliquot) "foo" needs to alter a Sample object, either the first argument or from the second argument it can extract its Sample. For example: foo (Sample sample, Aliquot aliquot) { Sample out = null; if (sample != null) out = sample else out = aliquot.getSample() return out; } But that is so un-elegant, other than reading the API a developer does not know the reference of the first argument overrides the Sample of the second argument. Now, I could change "foo" to foo (SomeMagicalObject bar) where SomeMagicalObject is a tuple for Sample and Aliquot and holds some logic ... etc. But I am wondering, are there some patterns for this question?

• Filling SWT table object using a separated thread class ...

  - by erlord

  Hi all I've got a code snippet by the swt team that does exactly what I need. However, there is a part I want to separate into another class, in particular, the whole inline stuff. In response to my former question, it has been suggested that Callable should be used in order to implement threaded objects. It is suggested to make use of an implementation of runnable or better callable, since I do need some kind of return. However, I don't get it. My problems are: In the original code, within the inline implementation of the method run, some of the parents objects are called. How would I do this when the thread is separated? Pass the object via the C'tor's parameter? In the original code, another runnable object is nested within the runnable implementation. What is it good for? How to implement this when having separated the code? Furthermore, this nested runnable again calls objects created by the main method. Please, have mercy with me, but I am still quite a beginner and my brain is near collapsing :-( All I want is to separate all the threaded stuff into another class and make the program do just the same thing as it already does. Help please! Again thank you very much in advance for any useful suggestions, hints, examples etc... Regs Me

• JUnit - stop it from exiting on finish?

  - by waitinforatrain

  Hi guys, Quick JUnit question. I'm running some unit tests that involve starting up the GUI and doing a load of stuff. I would like to see the results after the test to confirm it visually. However, it gets to the end of the code and exits, as it should. If I want to override this, I put a breakpoint on the last line of the test. This is pretty awkward though. Is there some option to stop it from exiting?
