With the ACDK class acdk::java::JavaObject you can use any Java class
inside C++ using the standard DMI interfaces.

The Hello World example
The Hello World example
// create a new java object
::acdk::java::RJavaObject jo = new ::acdk::java::JavaObject("java/lang/StringBuffer",
(const char*)"Hello");
// call the method append of the the java object
jo->invoke("append", (const char*)" Java from ACDK");
// call the method toString of the Java object
RObject str = (RString)jo->invoke("toString");
// get the static public member of the java object
RObject jout = ::acdk::java::JavaObject::peek_static("java/lang/System", "out");
// call the invoke method of the ::acdk::langObject
// The DMI automatically dispatches the call to the
// corresponding Java Object
jout->invoke("println", str);
RObject aout = System::out;
// Same interface works also with ACDK objects.
aout->invoke("println", str);

DMI Interface
The standard DMI interface works with following exceptions:
- Object::peek_static and Object::poke_static
does not map directly to the corresponding Java member.
You can use JavaObject::peek_static or Object::invoke_static(classname, "peek_static", membername) instead.
