When starting ArgoUML from a command line, there are several extra possibilities. Try typing:
java -jar argouml.jar -help
You will see the instructions:
Usage: [options] [project-file] Options include: -big use big fonts -huge use huge fonts -nosplash don't display Argo/UML logo -noedem don't report usage statistics -nopreload don't preload common classes -profileload report on load times -norecentfile don't reload last saved file -command <arg> command to perform on startup -batch don't start GUI You can also set java settings which influence the behaviour of ArgoUML: -Duser.language [e.g. en] -Duser.country [e.g. US] -Dforce.nativelaf [force ArgoUML to use the native look and feel. UNSUPPORTED]
A common problem is that the User Interface is shown in the wrong language. Below is an easy way to switch back to the English UI. Please be carefull: the language is in lowercase, the country in uppercase!
java -Duser.language=en -Duser.country=US -jar argouml.jar
