Help trying to run this java app (Calendar, notepad, weather...)

Looking for cool things on Google Code I came across these nice old project, called Koper: https://code.google.com/archive/p/ko...lingKoper.wiki

It's a Java app that has an ebook reader, a calendar, a notepad, a weather application and more.

Some screenshots:





Unfortunately, after following its installing instructions, it does not work at all in my Kobo. But it works perfectly on my computer when I open it with the Java runtime environment

Inside the Kobo, running the "java" binary does not produce any output. In Debian, typing "java" gives this:

Quote:
Usage: java [-options] class [args...]
(to execute a class)
or java [-options] -jar jarfile [args...]
(to execute a jar file)
where options include:
-d32 use a 32-bit data model if available
-d64 use a 64-bit data model if available
-client to select the "client" VM
-zero to select the "zero" VM
-dcevm to select the "dcevm" VM
-server is a synonym for the "client" VM [deprecated]
The default VM is client,
because you are running on a server-class machine.


-cp <class search path of directories and zip/jar files>
-classpath <class search path of directories and zip/jar files>
A : separated list of directories, JAR archives,
and ZIP archives to search for class files.
-D<name>=<value>
set a system property
-verbose:[class|gc|jni]
enable verbose output
-version print product version and exit
-version:<value>
Warning: this feature is deprecated and will be removed
in a future release.
require the specified version to run
-showversion print product version and continue
-jre-restrict-search | -no-jre-restrict-search
Warning: this feature is deprecated and will be removed
in a future release.
include/exclude user private JREs in the version search
-? -help print this help message
-X print help on non-standard options
-ea[:<packagename>...|:<classname>]
-enableassertions[:<packagename>...|:<classname>]
enable assertions with specified granularity
-da[:<packagename>...|:<classname>]
-disableassertions[:<packagename>...|:<classname>]
disable assertions with specified granularity
-esa | -enablesystemassertions
enable system assertions
-dsa | -disablesystemassertions
disable system assertions
-agentlib:<libname>[=<options>]
load native agent library <libname>, e.g. -agentlib:hprof
see also, -agentlib:jdwp=help and -agentlib:hprof=help
-agentpath:<pathname>[=<options>]
load native agent library by full pathname
-javaagent:<jarpath>[=<options>]
load Java programming language agent, see java.lang.instrument
-splash:<imagepath>
show splash screen with specified image
See http://www.oracle.com/technetwork/ja...ion/index.html for more details.
So I guess that the problem here is that java does not run successfully at the Kobo.

I was wondering if any of you Java wizards out there knew what I need to do in order to be able to run this
