pojo

I'm looking for a way to directly convert some POJO to a Jackson TreeModel . I know that a translation from POJO-to-JSON-String exists, and TreeModel-to-JSON-String is supported — hovewer I am looking for a POJO-to-TreeModel translation. Is there a way? The use-case is as follows: Server-side templating is done with the Java implementation of Mustache. This uses Jackson's TreeModel. After that, I need a slimmed-down version of the TreeModel on the client-side, so I want to be able to first filter the TreeModel, serialize that to JSON, then send it to the client-side for further processing.

I have an object graph that I would like to convert to and from JSON and XML, for the purposes of creating a REST-style API. It strikes me that someone must have done this already, but a quick search using Google and Stack Overflow reveals nothing. Does anyone know of a suitable (Apache or equivalent license preferred) library to do this? NimChimpsky GSON from google : http://code.google.com/p/google-gson/ , or Jackson the library used in spring : https://github.com/FasterXML/jackson and I would concur with others suggesting jaxb for XML to pojo, well supported lots of tools : its the standard

I usually tend to define the model layer of my apps using POJO's, such as Article, Comment, etc. I was about to implement an AlphabetIndexer in the adapter of one of my ListViews. Right now this adapter accepts a Collection of Articles, which I normally get from my wrapper around an SQLiteDatabase. The signature of the AlphabetIndexer constructer is as follows: public AlphabetIndexer (Cursor cursor, int sortedColumnIndex, CharSequence alphabet) Since this doesn't accept a Collection or something similar, just a Cursor, it got me wondering: maybe I shouldn't be creating objects for my model,

I am attempting to map the results of a Native query to a POJO using @SqlResultSetMapping with @ConstructorResult. Here is my code: @SqlResultSetMapping(name="foo", classes = { @ConstructorResult( targetClass = Bar.class, columns = { @ColumnResult(name = "barId", type = Long.class), @ColumnResult(name = "barName", type = String.class), @ColumnResult(name = "barTotal", type = Long.class) }) }) public class Bar { private Long barId; private String barName; private Long barTotal; ... And then in my DAO: Query query = em.createNativeQueryBar(QUERY, "foo"); ... set some parameters ... List<Bar>

What does the term Plain Old Java Object (POJO) mean? I couldn't find anything explanatory enough. POJO's Wikipedia page says that POJO is an ordinary Java Object and not a special object. Now, what makes or what doesn't make and object special in Java? The above page also says that a POJO should not have to extend prespecified classes, implement prespecified Interfaces or contain prespecified Annotations. Does that also mean that POJOs are not allowed to implement interfaces like Serializable , Comparable or classes like Applets or any other user-written Class/Interfaces? Also, does the above

I'm creating an application using JavaFX 2. I intend to isolate the UI from data and logics. Considering that, I have a lot of data objects like this: public class Entity { private String m_Value; public Entity(String value) { m_Value = value; } public String getValue() { return m_Value; } public void setValue(String value) { m_Value = value; } } I'm having a hard time creating a binding between the m_Value attribute and the textProperty of a Label, for instance. Another similar question here suggested people to use JFXtras, however I'm not sure I'm allowed to use that (company restrictions).

I'm looking for an article or tutorial that gives an example of what an up-to-date MVC pattern (2.0?) should look like with the Swing framework. Also, being more used to a layered architecture, I'd like to know how the domain objects or POJOs fit into the picture. Am I right in assuming that they are separate and called by the model? As for the pattern itself, are there widely used conventions in terms of grouping classes into packages? TIA, James P. That's a big question. I'll share some thoughts with you I have on this subject and see what comes out of it. Swing is more Model->View than

I cannot find difference between them. Does anyone know how to differentiate them? POJO or "Plain Old Java Object" is a name used to describe "ordinary" Java objects, as opposed to EJBs (originally) or anything considered "heavy" with dependencies on other technologies. DTO or "Data Transfer Object" is an object for... well... transferring data, usually between your "business" classes and persistence layer. It typically is a behavior-less class much like a C-style struct. They are an outdated concept. Jon A POJO is just a simple Java object, the acronym is used to emphasize that it really is
