For the purpose of a project, I need to capture a live feed from a Panasonic BL C131 IP cam. The video is encoded either in MPEG4 or in MJPEG, and I can manage to get and display the stream. The sound stream in the other hand is encoded in g721 (now superseded by g726 - 32kbits/s - 8Khz - 4 bits of quantification), and I don't how to decode it. Has anyone already struggled with this issue ? I'm opened to suggestions and/or solutions. Thanks.

Executing native process inside WEB-INF

mac01021 — Mon, 12 Oct 2009 13:59:24 -0400

Grettings, all.

I am running Apache Tomcat 5 under Red Hat Linux.

Generally, I deploy web applications using Tomcat's "Manager" application, which allows one to upload a WAR file over the network and have it automatically deployed.

The specific webapp that I am trying to deploy includes some native executable programs inside its WEB-INF directory which are to be executed via system calls from a java servlet.

However, when the Tomcat Manager uploads and deploys my WAR file, it creates the native programs without assigning execute permissions to the tomcat user.

Why Ant and Maven are weak

iirekm — Sat, 26 Sep 2009 05:56:07 -0400

At my company among other tasks I am often responsible for ‘technical’ things, which also means working with Maven and Ant from time to time. Some time ago we used Ant, now we use Maven. When project grows and grows both tools are bad. In this article I’ll explain why.

Visual Java?

I'm currently preparing to get training in Java - in hopes of making myself more marketable in the software developer market - by working through the book "Teach Yourself Programming with Java in 24 hours". It seems like the language is mostly text based (i.e. - we don't use visual tools, like Visual Studio 2005 for C# or VB, to build GUI's). Is this true? Or are there visual methods I don't know about?
