My Java RCP application prompts the user for username and password upon start-up. How could I use these credentials to do authentication against the native OS without using JNI to port some C libraries? Thanks!
PS. If possible, pure Java implementation without using third-party libraries will be very much preferable.

I have a file that contains some amount of plain text at the start followed by binary content at the end. The size of the binary content is determined by some one of the plain text lines I read.
I was using a BufferedReader to read the individual lines, however it exposes no methods to refer to read a byte array. The readUTF for a DataI...

Hi everyone,
I've a project at the moment, in Java, which uses a filetype which is inherently in the YCbCr colorspace. Within this, there is a lot of number crunching happening behind the scenes (which I've had to code) to convert to RGB from the YCbCr values. This is done per-pixel, per-frame, at 25 frames per second...

Hello.
I have a Java program which prints to a HTML file. Another method reads in this file and prints it to the editor pane.
My problem is that the color orange doesn't work. My code is as follows:
print.println("<html><p><br><font color=\"orange\">");
When I pass this html file into the editor pane all the colors are right. Red, ye...
Non-blocking TCP/IP SocketChannels and Selector in NIO help me to handle many TCP/IP connections with small number of threads. But how about UDP DatagramChannels? (I must admit that I'm not very familiar with UDP.)
UDP send operations don't seem to block even if the DatagramChannel is not operating in blocking mode. Is there really a...
I am maintaining two very similar schedulers - one in Java and one in C#. The C# version was originally created using JLCA and then modified by hand. The Java version has been modified quite significantly over the last few weeks by someone else (so I have to track down his changes), and I am wondering whether to reconvert it using one o...
Hello all,
I am currently doing some work for a company that runs a legacy web app built on Java Servlets (the system pre-dates JSP's, although they now use them when building new pages). The code base is a big jumbled mess as its around 10 years of building on top of an out of date framework. They have very little consistency in the co...
I'm trying to forward my IDE, Netbeans, over ssh to the Xming server on my Windows Desktop. I'm able to get Netbeans to launch and run, but the fonts look terrible because they aren't being anti-aliased. I've uploaded a screenshot here.
If I launch Netbeans from Gnome on the linux box itself, the fonts look fine, so it must be a probl...
What's the most efficient way to put as many bytes as possible from a ByteBuffer bbuf_src into another ByteBuffer bbuf_dest (as well as know how many bytes were transferred)? I'm trying bbuf_dest.put(bbuf_src) but it seems to want to throw a BufferOverflowException and I can't get the javadocs from Sun right now (network problems) when I...
My primary development experience is in Java, although I have some C# experience as well. I have a library of material that I turn to often for those things that you do just infrequently enough that you don't remember the details from the last time you did something similar. The most valuable aspect of this library is that it's large e...
I have a java program that parses an XML document using xerces API.
My parsing class extends org.apache.xerces.parsers.XMLDocumentParser, overloading the startElement, endElement, characters methods.
Since it's a complicated XML document that is written by hand (mainly some kind of configuration elements), classic validation by xsd or ...
