Oops I didn't notice the above
have you tried:
Class solverClass;
solverClass = loader.loadClass(solverName);
Solver theSolver = null;
try {
theSolver = (Solver)solverClass.newInstance();
}
catch (Exception e){ // more better exceptions available
log("couldn't cast, not a Solver!");
}
return theSolver;
