Is possible to get the CLASSPATH using Java commands?

Blablabla.getClasspath() or something like this...

Thanks in advance.

The system-Property "java.class.path" contains the classpath.
Inside a jar this wont work, because the class-path defined
in the manifest is not set.
Perhaps you can find some info from the current ClassLoader?

It will most definitely work - whether or not this meets the objective is
another matter.
Calling System.property("java.class.path") will always return the
java.class.path system property, regardless of any VM invocation properties.

this is true, but if you write a manifest
containing "Class-Path: lib/abc.jar config/" and start the jar using
"java -jar my.jar" the java.class.path property is empty, thogh the
lib/abs.jar is loaded and config-files in config/ are found.
Which means the Jar-File Class-Loader does not only
look in the java.class.path
