When using Maven to build an executable JAR, how do I specify the JVM arguments that are used when the JAR is executed? I can specify the main class using <mainClass>. I suspect there's a similar attribute for JVM arguments. Specially I need to specify the maximum memory (example -Xmx500m). Here's my assembly plugin: <plugin> <a...
I have an application that I'm trying to wrap into a jar for easier deployment. The application compiles and runs fine (in a Windows cmd window) when run as a set of classes reachable from the CLASSPATH.

I can of course create a .bat file to launch my application, but is it possible to make Vista execute a .jar as required? ...

In Eclipse, I have everything working. When I package my project as a runnable Jar and execute it by double-clicking, everything still works. But when I have a...
I want to be able to distribute by executable JAR without having to make the user upgrade to the latest version of the JRE. How can I package a JRE into the JAR so that they can run the jar with no JRE installed on their system? ...
Hi all, Just finished a little app that I want to distribute and at the moment for windows platform it is just an executable jar. Is there anyway to give this jar another image than the java cup? Thanks ...

When I run this program in Eclipse, it prints out "Hello World!", but when I call the jar-file from the com...
