Kindles have a Java Virtual Machine located at /usr/java/bin/cvm, so i'm doing some investigations :

I'm able to run a java (non kindlet) textual app with the command:

/usr/java/bin/cvm -jar FileName.jar

or

/usr/java/bin/cvm -cp FileName.jar ClassName

but, if i try to run a (non kindlet) swing app i get this error:

if include in the classpath the /usr/java/lib/agui.jar (which contains the java/awt/Component), i get:

if i try to launch a kindlet:

(yes, i know that i can also use the command:

lipc-set-prop com.lab126.appmgrd start file:///mnt/us/documents/Test.azw2

but i'd like a more "direct" way: launching kindlets via lipc hides for example all System.out.println messages)


if i include the java/awt/Component:

there is any way to launch a swing app or a kindlet via cvm?
