Is it possible in Java to create a PriorityQueue of objects where the key that decides the priority is the member of the object? All the examples I see on net insert an integer into the PriorityQueue and retrieve them. I'm looking for an implementation that would insert an instance of an object and is retrieved based on one of its membe...
In order to minimize the number of database queries I need some sort of cache to store pairs of data. My approach now is a hashtable (with Strings as keys, Integers as value). But I want to be able to detect updates in the database and replace the values in my "cache". What I'm looking for is something that makes my stored pairs invalid ...

From what I know of MVC outside of the Java world (PHP and Ruby on Rails), all requests are first sent to the front controller (or dispatcher... or boostrap, etc.), and the front controller looks to the request path pattern in the URL in order to determine what class/method should handle the request. In Java MVC, it appears that servlets...

I have my java application configured to use 5G memory. I got an OutOfMemory out of blue. I inspected the gc log and found plenty of memory left: young generation occupies 4% allocated space, tenure generation occupancy is 5% and perm generation is 43%.

The @EJB annotation can be use in "managed clients" to access an EJB. One can place this annotation in a servlet class, declaring a member variable. public class MyServlet extends HttpServlet { @EJB private MyWorkerInterface theWorker; } That @EJB annotation is expanded to JNDI lookups that (I assume) are executed when th...

Instead of using a selector in the usual way, where for each ready channel a message can be determined and sent, I'd like to choose whichever connection is currently ready and send a message there. Presumably this can be done by throwing all the channels into a selector for reading and marking them ready for reading if they come out, t...

I've written a Java program to generate an m3u file based on a CD ripped from k3b which pretty much preserves special character encodings in artist, album and track names. I then place these m3u files on a server and generate a GWT web application where the m3u file name is the target of an HTML anchor tag. For 99+% of cases, this all ...

I'm looking for a fail-safe way to round-trip between a JVM class file and a text representation and back again. One strict requirement is that the resulting round-tripped JVM class file is exactly functionally equivalent to the original JVM class file as long as the text representation is left unchanged. Furthermore, the text represen...
