Essentially.  We include a tool "java2ada" with our AppletMagic(tm)
Ada=>Java-byte-code compiler which will generate an Ada package
spec given a java byte-code ".class" file.  You then "register"
this package spec (using our "adareg" tool) and you can now call
any of the public methods, and reference andy of the
public fields, of the Java class, from Ada.  See "www.appletmagic.com"
or "www.inmet.com/javadir/download"

Yes, AppletMagic (and the Ada=>Java component of ObjectAda), via
the "java2ada" tool.

: 2) "Does some brand(s) of Ada95 linker know how to link Java things created
: by an Ada95 compiler to Java things created by a Java compiler?"

Yes, the above compilers generate Java byte codes, and so they
dynamically link to byte-codes compiled by a Java compiler.

: Thanks.

: p.s. I think that no Ada95 compilation system handles this but that it is
: theoretically possible.
