Hi! I am developing a RESTful web service. I have a bunch of entity classes (mostly JPA entities, but also other beans). There are gazillions of object mapping, serialization, binding and whatnot libraries out there.

Date.getTime() returns milliseconds since Jan 1, 1970. Unixtime is seconds since Jan 1, 1970. I don't usually code in java, but I'm working on some bug fixes. I have: Date now = new Date(); Long longTime = new Long(now.getTime()/1000); return longTime.intValue(); Is there a better way to get unixtime in java? UPDATE Based on John...
I'm new to Java portlets, and am trying to get a handle on how these things work at a fairly basic level. I'm confused now about how to have multiple "views" in my portlet. Let's say my portlet will be used for CRUD operations. For the sake of simplicity, I'm imagining that when a user first views the portlet they'll see a table wit...
I built a couple working examples that upload an image to the server and display it on the page without refreshing. One approach was the iframe method, and the other was DWR (version 3). I wonder if anyone has an example using SWFUpload. I am not quite sure how it hooks into the server side code. Thanks! ...

Basically we have a class like this: public class AnImporter implements Runnable { // some methods, attributes, etc. } But where to put the main method? I concider it a good practice to "keep code where it belo...

Hi I'm taking an independent project during the summer at school. The prof. told me to come up with a good topic or a good project. He likes doing GUI in Java and I like the same too. So I was thinking a on doing a project in Java instead of doing research. He told me to present to him a good topic and explain what I am planning on do...
I've done some HotSpot optimization in Java. However, I'm now concerned about space in relation to loading classes (ie. only need one method in a class, don't want to load others). How would I go about doing so? ...

I wrote a linked list implementation for my java class earlier this year. This is a generic class called LList. We now have to write out the merge sort algorithm for a lab. Instead of creating a new List implementation that takes Ints, I decided to just reuse the generic list I had created before. The problem is how do I compare two gen...
I would like to do some more learning of facelets. Now that java is a supported Google app engine language, is there anything in the facelets implementation that would prevent use on app engine? Edit: This page at google now has a list of various frameworks and their status in regards to app engine. http://groups.google.com/group/googl...

Hey everyone, When implementing a Matrix construct using arrays, which would be more efficient? Using a 1D array, or an array of arrays (2D)? I would think a 2D is more efficient as you already have the X and Y coordinates of an element, where in a 1D implementation you have to calculate the index. Any thoughts? Thank you Edit: it ...
I have a database table that uses Sql Server 2005's uniqueidentifier column. I know how to create GUIDs in C#... string newid = System.Guid.NewGuid().ToString(); However, the application that is inserting into this database is running Java. Is there a way to generate Sql-Server-compatible GUIDs using Java code? (NOTE: generating th...

I really like the concept of modular bundles as implemented by OSGi. I also like "managed deployment" services like Google AppEngine (for web application) or Java WebStart (for client software). These two ideas seem to complement each-other rather well conceptually. However, the OSGi standard includes a couple of features that make i...
How can I have one window move with another? i.e., I'd like a JDialog to follow a JFrame when the JFrame is being dragged. If the JFrame moves by (+5, +20), the JDialog needs to move the same. I've tried using ComponentListeners, but I only receive drag events in chunks which causes the JDialog window to be jumpy while dragging the ma...
Hey guys and gals I'm using the Apache Cocoon framework, set up several eons ago for the web app I'm developing. I don't know if its how cocoon is set up for everyone, or its if some 'special' configuration my company has performed, but this is what happens. In order for cocoon to use ANY class files, they must be bundled up into a JA...
