I'm working in a Continuous Integration environment and part of the automated build process includes the compilation of Maven managed projects. What I want to know is if there is a way to make the Maven build independent of the network connection. Currently we have the all the jar's that we need installed in the repository but the pro...

Are there any good libraries for streaming live video using Java? Ideally both ends of the pipe should be written in Java but I am mostly concerned about the video player. What software would you recommend? UPDATE: It seems that VLC introduces a 1-2 second delay. I need video streaming that is truly live. The record-to-playback delay mu...
I am testing out MigLayout for a project, and I can't seem to figure out the MigLayout way of controlling the size of the whole panel which is being layed out. I am adapting the example in the MigLayout whitepaper. Also, I am writing in Python and using Jython rather than writing in Java. That said, here is my current code. layout = Mig...

So, this is an efficiency question. I have two collections - an ArrayList and a Stack. I use the stack because I needed some simple pop/push functionality for this bit of code. The ArrayList is essentially the out variable as this is a small section of code in the function. So, I the variables are defined as such, then code is run to ...

Hello, Sorry for the odd choice of words for the title, however, "border" seems to be the inappropriate term. While it is true that the visible line surrounding an icon in a JToggleButton can be made invisible by using setBorderPainted(false), the same is not true for JCheckBox and JRadioButton. I can not use the JToggleButton and the...
In my Java application, I have PDF files that I eventually need to convert to PCL and send to a RightFax server. I'll also need to embed codes in the PCL files that RightFax will read to know where to send the fax. What's the best approach towards doing this? Searching online, it seems like I could use Java's StreamPrintService to pr...
I'm timing some things, which I can't just put in a long loop. And I need to time them to see how long they take to complete, but it seems like the timer has a 15-16 ms accuracy in java? How can i get around this? ...

I've used the NStoPkg.properties file successfully in the past to map the webserver namespace to a convenient java package name with config lines like this: http\://webserver/somedir/service=com.blah.blah But w...
Hello chaps, I'm working on a web app that uses Jersey. I'm trying to implement a get-after-post sort of thing using a URIBuilder and a seeOther response. The aim is to redirect to the same URI the browser is already on, but to force a GET. It works a bit like this: Request comes in via PUT PUT request processed SeeOther response retu...

I'm trying to solve an allocation problem and one of my LHS goes like this $leftAlloc: SlotAllocation($leftRes: resource ) $rightAlloc: SlotAllocation(this != $leftAlloc, resource == $leftRes) for some reason the second statement does not match anyt...
I am really unfamiliar with working with threads, so I was hoping someone could help me figure out the best way to do this. I have a JButton in my java application...when you click on the button, I have a Process Builder that creates a process which executes some external python code. The python code generates some files, and this can t...

In Jboss I can just put the properties files into $JBOSS_HOME/server/default/conf, and they are loaded onto the system classpath and I can access them without any...
I am writing a webservice that allows users to post files and then retrieve them at a URL (basically think of it as the RESTful Amazon S3). The issue I came across was rather then return a byte[] from my Oracle query (Spring JDBC) I am returning an InputStream and then streaming the data back to the client in chunks. This (IMO) is a mu...
