I created a simple Hello World Swing application that compiles and runs just fine in Eclipse. I'm now trying to transfer this application over to a Maven package structure and run it as a Java Web-Start application, which is causing me great pain. After running "mvn clean install", javaws appears to load for several seconds and then quit.
Here are a few things for reference. My (very simple) project should be fully reproducible:

Thanks.
PS: The project I'm using is from an example on Shaun Abram's website, here: http://www.shaunabram.com/swing-webstart-maven-example/. It was designed to interface with tomcat and run on a server but I feel like I should be able to get this to work locally. I'm just using the SwingWebstartMaven-Client branch and ignoring the SwingWebstartMaven-Web branch.
PPS: I feel like I should be able to rename the package structure, but for some reason I can't. Whenever I try replacing shaunabram with my last name in the directory structure, the package declaration in my java file, and in the pom.xml file, it complains with:
[ERROR] The project com.kothur.swingwebstartmaven:SwingWebstartMaven-Client:1.0 (/media/reivei/New Volume/Project Files/SwingWebstartMaven/SwingWebstartMaven-Client/pom.xml) has 1 error
[ERROR] Non-resolvable parent POM: Failure to find com.kothur.swingwebstartmaven:SwingWebstartMaven:pom:1.0 in http://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced and 'parent.relativePath' points at wrong local POM @ line 6, column 13 -> [Help 2]
EDIT: The problem is identical to this one: I am not able launch JNLP applications using "Java Web Start"? except on an Ubuntu machine. I'm having difficulty understanding how the author's solution would translate over to Ubuntu (I tried setting JAVAWS_HOME to my jre bin and rerunning javaws but it gave me the same problem (i.e. the Java 6 splash screen starts and then stops with no program to be found)). Double-clicking launch.jnlp runs it in Java 7 (not what I want) and spits out
"Error: Unable to load resource: http://localhost:8080/SwingWebstartMaven-Web/webstart/launch.jnlp."
After that point, I tried a few other things. The primary pom.xml had the tomcat plugin, which I wasn't using, so I tried deleting it, which didn't do anything. I then tried actually creating a tomcat server and putting the project folder in /var/lib/tomcat7/webapps/. This also effected no change in the error.
