A limitation of Lombok is the fact that it is closely tied to the java compiler. Since the annotation processor API only allows creation of new files during the compilation (and not the modification of the existing files) lombok uses that API as a entry point to modify the java compiler. Unfortunately these modifications of … Read more
It is not recommended to dynamically prepare the URL at run time, especially based on ServletRequest. This is primarily because you have no idea of the URL that users would be using to access the application – the application server could be behind a web server, a firewall or a load balancer. To keep it … Read more
I think I may know what is going on. In your working web.xml you have set your servlet to be the default servlet (/ by itself is the default servlet called if there are no other matches), it will answer any request that doesn’t match another mapping. In Failed 1 your /* mapping does appear … Read more
RESTful is more an architecture style than a different technology. In server perspective, it is designed to be entirely stateless and self-contained on a per-request basis (i.e. there are no sessions). In client perspective, it’s more a way of getting information in different formats via URLs with (self-documenting) path parameters instead of request parameters. Surely … Read more
The difference between the two tags is that the way they work. Well, I will say an example so that you can imagine it better. Assume you have two pages, pageA, and pageB. In pageA you wrote the include tag. In this case the control was in pageA til you called the include tag. At … Read more
Thymeleaf th:each allows you to declare an iteration status variable <span th:each=”task,iter : ${foo.tasks}”> Then in the loop you can refer to iter.index and iter.size. See Tutorial: Using Thymeleaf – 6.2 Keeping iteration status.
In my understanding, you will not be able to process a plain List via JAXB, as JAXB has no idea how to transform that into XML. Instead, you will need to define a JAXB type which holds a List<RelationCanonical> (I’ll call it Type1), and another one to hold a list of those types, in turn … Read more
The people that wrote CDI gave you one big object factory; they did the work for you, better than you would. It’s XML configuration or annotation driven, so you don’t have to embed everything in code. Dependency injection engines, like Spring, do a lot more than your factory. It’ll take more than one factory class … Read more
Remove the standard.jar. It’s apparently of old JSTL 1.0 version when the TLD URIs were without the /jsp path. With JSTL 1.2 as available here you don’t need a standard.jar at all. Just the jstl-1.2.jar in /WEB-INF/lib is sufficient. See also: How to install JSTL? The absolute uri: http://java.sun.com/jstl/core cannot be resolved Our JSTL wiki … Read more
You can access individual elements with the array [] operator: <c:out value=”${attachments[0].id}” /> This will work for arrays and lists. It won’t work for maps and sets. In that case you must put the key of the element inside the brackets.
