I am trying to print the current date when the template is activated. I have read that I have to pass a new Date() Java object to the template, but I don't know how to do that or where to put it in the code. Does someone know how to pass a Java object to the template in this case? Thank you !! Actually you don't have to pass a new Date() to your template, because placing a timestamp into a template's output is quite common and therefore FreeMarker provides a special variable called .now which returns the current date and time. You can use it in your template like this: Page generated: ${.now}

I work on a project where we have to create unit tests for all of our simple beans (POJOs). Is there any point to creating a unit test for POJOs if all they consist of is getters and setters? Is it a safe assumption to assume POJOs will work about 100% of the time? Duplicate of - Should @Entity Pojos be tested? See also Is it bad practice to run tests on a DB instead of on fake repositories? Is there a Java unit-test framework that auto-tests getters and setters? The rule in TDD is "Test everything that could possibly break" Can a getter break? Generally not, so I don't bother to test it.

I have a POJO, and a (currently not-yet-built) class that will return Lists of it. I'd like to automatically generate the code necessary for the POJO to be accessed as a Map. Is this a good idea, is it possible to do automatically, and do I need to do this manually for every POJO I want to treat this way? Thanks, Andy You can use Commons BeanUtils BeanMap for this. Map map = new BeanMap(someBean); Update : since that's not an option due to some apparent library dependency problems in Android, here's a basic kickoff example how you could do it with little help of Reflection API : public static

In the company that I work for we have this major discussion on whether it should be better to use wrapping classes for primitives (java.lang.Integer, java.lang.Long) or whether to use the primitive types directly in the POJOs that map Entities to Tables in Hibernate. The idea is that we want these values to not be null in the database. The arguments in favor of using primitives: Handling these values as int means that they can never be null, in this way making it impossible to inadvertently get a null reference on the field. int=32/64 bits of memory. Integer = 16 bytes of memory and is also

Is there any way to take an unknown schema xml file and convert the values, tags, etc from the xml file into pojo? I looked at jaxb and it seems like the best way to use that is if you already know the xml schema. So basically, I want to be able to parse the tags from the xml put each into its own object maybe through the use of an arraylist. Did I just not fully understand what jaxb can or is there a better tool that can do this, or is it just too hard to implement? In the hope that this helps you to understand your situation! public static void dumpAllNodes( String path ) throws Exception {

I'm about to start on a small project which goal is to end up with a web xml/json api. I'll be writing it in Java, and I'll be using the restlet library. How do I approach the xml/json duality? I know I can use JAXB to "convert" pojos to xml (and back), but how do I automate this for json? Is there any functionality in the restlet library I can leverage? Restlet allows you to directly work with POJOs within your server resources at the level of REST annotated methods, as described below: public class MyServerResource extends ServerResource { @Get public List<MyPojo> getList() { List<MyPojo>
