hello,

I'm trying to install umlet.
I have tried quite a lot of different configurations, but none worked.
Whether trying from the .jar itself (java -jar umlet.jar), whether using it as an eclipse plugin, or even trying wine umlet.exe, it always fails to load.
I think it might be caused by java itself, though I'm not sure.
I have tried both openJDK and the legacy java, but none worked.
java -version returns openJDK 1.6.

From eclipse, the error returned is:
Could not open the editor: The editor class could not be instantiated. This usually indicates a missing no-arg constructor or that the editor's class name was mistyped in plugin.xml.

From java -jar umlet.jar, the error is:
23 | ERROR | com.baselet.control.Main - "Initialization or uncaught outer Exception"
at java.awt.HeadlessException
[at ... etc...]

From wine, the error is wine: Install Mono for Windows to run .NET 2.0 applications.

I am looking for any solution that would make that software work.

Please help.

Thanks.

Example "UMLet 11.5.1 stand-alone" > umlet_11.5.1.zip
http://www.umlet.com/umlet_11_5_1/umlet_11.5.1.zip

cd Umlet/ && sh umlet.sh : The UMLet GUI application opens OK.

.

Well for me it doesn't:
sh umlet.sh gives the same error as java -jar umlet.jar:
27 | ERROR | com.baselet.control.Main - "Initialization or uncaught outer Exception"

sudo apt-add-repository ppa:flexiondotorg/java
sudo apt-get update
sudo apt-get install sun-java6-jdk

UMLet 11.5.1 stand-alone :
cd Umlet/ && sh umlet.sh : Same OK result.
