You can use the Java getClass method:
   (VALUE:getClass)
or:
   (invoke VALUE 'getClass)
or the "property" short-hand:
   VALUE:class

The Kawa manual attempts to document all the Kawa functions.
In the past I concentrated on documenting only Kawa extensions/differences
from standard Scheme (so you needed to also have a copy of R5RS/R7RS), but
I'm gradually making the Kawa manual more complete and self-contained.
(There may still be some R7RS procedures missing, though.)

There are also some implemented SRFIs, not all of which are fully documented
in the Kawa manual.  See:
   https://www.gnu.org/software/kawa/Implemented-SRFIs.html

Of course all of the Java APIs are always available, by using Java
method calls:
   https://docs.oracle.com/javase/8/docs/api/overview-summary.html
That is where you will find getClass documented:
   https://docs.oracle.com/javase/8/docs/api/java/lang/Object.html#getClass--
(the final '--' in the URL seems to be needed.)
